DETAILED DESCRIPTION OF THE INVENTION

Definitions

[0063] Unless otherwise stated, the following terms used in the specification and claims have the following meanings set out below.

[0064] It is to be appreciated that references to “treating” or “treatment” include prophylaxis as well as the alleviation of established symptoms of a condition. “Treating” or “treatment” of a state, disorder or condition therefore includes: (1) preventing or delaying the appearance of clinical symptoms of the state, disorder or condition developing in a human that may be afflicted with or predisposed to the state, disorder or condition but does not yet experience or display clinical or subclinical symptoms of the state, disorder or condition, (2) inhibiting the state, disorder or condition, i.e., arresting, reducing or delaying the development of the disease or a relapse thereof (in case of maintenance treatment) or at least one clinical or subclinical symptom thereof, or (3) relieving or attenuating the disease, i.e., causing regression of the state, disorder or condition or at least one of its clinical or subclinical symptoms.

[0065] A “therapeutically effective amount” means the amount of a compound that, when administered to a mammal for treating a disease, is sufficient to effect such treatment for the disease. The “therapeutically effective amount” will vary depending on the compound, the disease and its severity and the age, weight, etc., of the mammal to be treated.

[0066] The term “cancer” used herein will be understood to mean any neoplastic growth in a subject, including an initial tumour and any metastases. The cancer can be of the liquid or solid tumour type. Liquid tumours include, for example, tumours of haematological origin (haematological cancer), including, e.g., myelomas (e.g., multiple myeloma), leukaemias (e.g., Waldenstrom's syndrome, chronic lymphocytic leukemia, other leukaemias), and lymphomas (e.g., B-cell lymphomas). Solid tumours can originate in organs, and include cancers such as lung, breast, prostate, ovary, colon, kidney, and liver.

[0067] The term “cancerous cell” or “cancer cell” used herein will be understood to mean a cell that shows aberrant cell growth, such as increased cell growth. A cancerous cell may be a hyperplastic cell, a cell that shows a lack of contact inhibition of growth in vitro, a tumour cell that is incapable of metastasis in vivo, or a metastatic cell that is capable of metastasis in vivo. Cancer cells include, but are not limited to, carcinomas, such as myelomas, leukaemias (e.g., chronic lymphocytic leukaemia, myeloid leukaemia and B-acute lymphocytic leukaemia), lymphomas (e.g., follicular lymphoma, mantle cell lymphoma, diffuse large B-cell lymphoma or Hodgkins disease) and blastomas (e.g. retinoblastoma or glioblastoma).

[0068] The term “MYC” used herein will be understood to mean the whole family of regulator genes (transcriptional factors) that fall within the MYC gene family. Members of the MYC transcription factor family include c-MYC, MYCN and MYCL, and thus reference to “MYC” herein will be understood to covers all of such family members. The non-italicised terms “MYC”, “c-MYC”, “MYCN” or “MYCL” will, unless stated otherwise, be understood to mean the proteins derived from the corresponding MYC gene. For example, a reference to “MYCN” will be understood to mean the protein derived from the “MYCN” gene. Such nomenclature is consistent with the nomenclature used in the art. In certain instances, the terms “MYC”, “c-MYC”, “MYCN” and “MYd” may be used synonymously with the respective uncapitalised terms “Myc”, “c-Myc”, “N-Myc” and “L-Myc”.

[0069] The terms “overexpressed”, “overexpression” and “overexpressing” used herein may be taken to mean the expression (i.e. level/amount) of mRNA and/or protein found in a particular cell (i.e. cancer cell) is elevated compared to the expression (i.e. level/amount) of mRNA and/or protein found in a normal, healthy cell (i.e. a cancer-free cell). Thus, for example, a “MYC overexpressing cancer” will be understood to be a cancer which expresses elevated RNA transcript and/or protein levels of MYC compared to the RNA transcript and/or protein levels of MYC found in normal, healthy cells. Suitably, the MYC overexpressing cancer is a cancer wherein the levels of RNA transcript and/or protein of MYC are at least 25% greater than the RNA transcript and/or protein levels of MYC in a normal, healthy cell. More suitably, the MYC overexpressing cancer is a cancer wherein the levels of RNA transcript and/or protein of MYC are at least 50% greater than the RNA transcript and/or protein levels of MYC in a normal, healthy cell. Even more suitably, the MYC overexpressing cancer is a cancer wherein the levels of RNA transcript and/or protein of MYC are at least 100% greater than the RNA transcript and/or protein levels of MYC in a normal, healthy cell. Yet more suitably, the MYC overexpressing cancer is a cancer wherein the levels of RNA transcript and/or protein of MYC are at least 200% greater than the RNA transcript and/or protein levels of MYC in a normal, healthy cell. Most suitably, the MYC overexpressing cancer is a cancer wherein the levels of RNA transcript and/or protein of MYC are at least 400% greater than the RNA transcript and/or protein levels of MYC in a normal, healthy cell. The level of expression may be determined by any suitable means known in the art. For example, the level of expression of MYC may be determined by measuring MYC protein levels. The MYC protein levels may be measured using any suitable technique known in the art, such as, for example, SDS-PAGE followed by Western blot using suitable antibodies raised against the target protein. In addition, or alternatively, the level of expression of MYC may be determined by measuring the level of mRNA. The level of mRNA may be measured using any suitable technique known in the art, such as, for example, northern blot, quantitative RT-PCR (qRT-PCR) or immunohistochemical (IHC), see for example Kluk et al., PLos One, 2012, 7(4), 1-9.

[0070] The terms “transcriptional addiction” and “transcriptionally addicted” used herein are terms of the art and may be understood to refer to cancers, and more specifically cancer cells, that exhibit a dependence on the transcription of a particular oncogene for continued growth and proliferation. In such “transcriptionally addicted” cancers, reducing the transcription of the oncogene, or inhibiting the oncogene which the cancer cells are transcriptionally addicted to, results in significant apoptosis and/or differentiation of said cancer cells. Thus, it will be understood that the terms “MYC addiction” and “MYC addicted” refer to cancers, and more specifically cancer cells, that exhibit a dependence on the MYC oncogene for continued growth and proliferation.

[0071] The term “MYC dysregulated cancer” used herein will be understood to mean a cancer in which one or more of the regulation mechanisms of the MYC oncogene are altered (e.g. mutated) or stabilised. The term “regulation mechanisms” will further be understood to mean any normal process of the MYC gene such as, for example, transcription or translation. Thus, it will be understood that the term “MYC dysregulated cancer” suitably covers both: i) mutations to the MYC oncogene which result in, for example, overexpression of the protein/mRNA of MYC; and ii) mutations to the MYC oncogene which result in, for example, a stabilisation of the protein/mRNA of MYC.

[0072] The term “locus” used herein will be understood to mean the location of a gene on a chromosome. Thus, the term “MYC locus” will be understood to mean the position on a chromosome corresponding to the MYC gene. Hence, the term “one or more structural alterations of the MYC locus” will be readily understood to mean that one or more alterations (e.g. mutations, amplifications and/or chromosomal rearrangements) are present at a location of the chromosome which corresponds to the MYC gene.

[0073] The term “hydrocarbyl” used herein will be understood to mean any compound straight or branched chain saturated, unsaturated or partially unsaturated hydrocarbon groups.

[0078] As used herein, the term “carbocyclyl” (or “carbocycle”) is intended to mean any 3- to 13-membered carbon ring system, which may be saturated, partially unsaturated, or aromatic. The carbon ring system may be monocyclic or contain more than one ring (e.g. the ring system may be bicyclic). Examples of monocyclic saturated carbocycles include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl. Examples of bicyclic saturated carbocycles include bicyclooctane, bicyclononane, bicyclodecane (decalin) and bicyclooctane. A further example of a saturated carbocycle is adamantane.

A heterocyclyl (or heterocycle) group may, for example, be monocyclic or bicyclic. In a bicyclic heterocyclyl (or heterocycle) group there may be one or more heteroatoms in each ring, or only in one of the rings. A heteroatom may be S, O or N, and is preferably O or N.

[0088] The phrase “NMT inhibitor of the invention” means those compounds which display activity as inhibitors of the human N-myristoyl transferases (NMT) which are disclosed herein, both generically and specifically.

Therapeutic Uses and Applications

[0089] To their surprise, the inventors of the present invention have found that upon administering a NMT inhibitor to a cancer with overexpressed levels of the MYC oncogene, and/or to a cancer with one or more structural alterations in the MYC locus (e.g. one or more chromosomal rearrangements or mutations), a significant improvement in both the kill rate and time to kill of the cancer, together with a lowering of the concentration of NMT inhibitor needed to adversely effect the cell is achieved compared to administration of a NMT inhibitor to a cancer without overexpressed levels of the MYC oncogene.

[0090] Following much investigation, the inventors discovered there to be a significant correlation between the mRNA expression levels of, for instance, c-MYC and the responsiveness to an NMT inhibitor in three pharmacogenomics screens (see, for example, FIGS. 20 to 22). This correlation was observed using two different types of analysis (Spearman correlation between c-Myc expression and EC50, and dividing cells by high and low expression of c-Myc and comparing both groups) and was found to be observed for a selection of structurally diverse NMT inhibitors in different types of cancer cell lines (e.g. 676 to 913 cancer cell lines).

[0091] Furthermore, the inventors also observed that one or more structural alterations in the MYC locus (e.g. MYCN and MYCL) correlated significantly with an increased sensitivity to an NMT inhibitor. These observations were again consistent across three pharmacogenomics screens, and upon using a selection of structurally diverse NMT inhibitors and different cancer cell lines (676 cancer cell lines). See, for example, FIG. 26.

[0092] In addition to these strong correlations, the inventors also discovered that when the expression of c-MYC or MYCN was enforced in three different genetically modified cell lines, an increase in the responsiveness to an NMT inhibitor was observed, as evidenced by the lower effective concentrations of NMT inhibitor needed to impart cell death in cell lines with high MYC expression compared to those with low MYC expression, and also the shorter timeframes for cell death—see, for instance, FIGS. 4, 5, 14 and 15.

[0093] The oncogenes c-MYC and MYCN are common diagnostic markers for particularly aggressive types of malignancies and there are recent findings demonstrating that c-MYC and MYCN overexpression and/or mutation correlate strongly with some of the worst clinical outcomes (Jung et al., Tumor and Stem Cell Biology, 2016, 65(16), 7065-7070, Habermann et al., Blood, 2016, 128(22), 155, Xu et al., Genes Cancer, 2010, 1(6), 629-640). There therefore remains a need for improved treatments that are able to target cancers where one or more structural alterations of the MYC oncogene exist.

[0094] In line with the advantageous properties described hereinabove, the inventors have therefore discovered that the class of NMT inhibitor compounds, particularly the NMT inhibitor compounds defined herein, are especially well-suited for application in the treatment of cancers which: i) are addicted to the MYC oncogene; and/or ii) have one or more structural alterations in the MYC oncogene locus.

[0095] Thus, as mentioned above, the present invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a MYC addicted cancer. Suitably, the MYC addicted cancer is a cancer which is addicted to c-MYC and/or MYCN. In certain embodiments, the MYC addicted cancer is a cancer which is addicted to c-MYC, and, suitably, the MYC addicted cancer is a cancer which is transcriptionally addicted to c-MYC. In other embodiments, the MYC addicted cancer is a cancer which is addicted to MYCN, and, suitably, the MYC addicted cancer is a cancer which is transcriptionally addicted to MYCN.

[0096] In a particular embodiment, the present invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a c-MYC or MYCN addicted cancer, wherein the c-MYC or MYCN oncogene is overexpressed. Suitably, the present invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a c-MYC or MYCN addicted cancer, wherein the c-MYC or MYCN oncogene is overexpressed such that the levels of RNA transcript and/or protein of c-MYC or MYCN are at least 25% greater than the RNA transcript and/or protein levels of c-MYC or MYCN found in a normal, healthy cell. More suitably, the present invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a c-MYC or MYCN addicted cancer, wherein the c-MYC or MYCN is overexpressed such that the levels of RNA transcript and/or protein of c-MYC or N-MYC are at least 50% greater than the RNA transcript and/or protein levels of c-MYC or N-MYC found in a normal, healthy cell.

Genet., 2016, 48-176-182); and iii) activating mutations in the signal transduction pathways that augment MYC expression (Herranz et al., Nat. Med., 2014, 20, 1130-1137, Muncan et al., Mol. Cell Biol., 2006, 26, 8418-8426 and Weng et al., Genes Dev., 2006, 20, 2096-2109).

More suitably, the MYC oncogene dysregulated cancer is a c-MYC or MYCN oncogene overexpressing cancer, wherein the c-MYC or MYCN is overexpressed such that the levels of RNA transcript and/or protein of c-MYC or MYCN are at least 25% greater than the RNA transcript and/or protein levels of c-MYC or MYCN found in a normal, healthy cell. Most suitably, the MYC dysregulated cancer is a c-MYC or MYCN oncogene overexpressing cancer, wherein the c-MYC or MYCN is overexpressed such that the levels of RNA transcript and/or protein of c-MYC or MYCN are at least 50% greater than the RNA transcript and/or protein levels of c-MYC or MYCN found in a normal, healthy cell.

Even more suitably, the MYC addicted cancer, the MYC dysregulated cancer or the cancer comprising one or more structural alterations of the MYC locus, is neuroblastoma or triple negative breast cancer (e.g. basal-like breast cancer).

[0120] In a particular embodiment, the invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a blastoma, wherein said blastoma comprises one or more mutations of MYCN. Suitably, the blastoma is selected from a neuroblastoma, a retinoblastoma and a glioblastoma. Most suitably, the invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a neuroblastoma, wherein said neuroblastoma comprises one or more mutations of MYCN.

[0121] In another particular embodiment, the invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a c-MYC addicted cancer, wherein the c-MYC addicted cancer is a breast cancer. Suitably, the invention provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in the treatment of a c-MYC addicted cancer, wherein the c-MYC addicted cancer is a triple negative breast cancer (e.g. a basal-like breast cancer) or a breast invasive carcinoma.

[0122] The present invention also provides a method for the treatment of a MYC addicted cancer in a subject in need of such treatment, said method comprising administering a therapeutically effective amount of a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof. Suitably, the MYC addicted cancer is any one of the MYC addicted cancers described hereinabove.

[0123] Further provided is a method for the treatment of a MYC dysregulated cancer in a subject in need of such treatment, said method comprising administering a therapeutically effective amount of a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof. Suitably, the MYC dysregulated cancer is any one of the MYC dysregulated cancers described hereinabove.

[0124] Further provided is a method for the treatment of a cancer comprising one or more structural alterations of the MYC locus in a subject in need of such treatment, said method comprising administering a therapeutically effective amount of a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof. Suitably, the cancer comprising one or more structural alterations of the MYC locus is any one of the cancers described hereinabove.

[0125] According to a further aspect of the present invention, there is provided a method for determining whether a subject with a cancer will benefit from treatment with an NMT inhibitor, said method comprising the steps of: [0126] i) taking a sample of cancer cells taken from said subject; [0127] ii) analysing the cancer cells of step i) to check for the presence of one or more structural alterations (e.g. chromosomal rearrangements, copy number gains and/or mutations) in the MYC locus; [0128] iii) determining whether one or more structural alterations (e.g. chromosomal rearrangements, copy number gains and/or mutations) are present in the MYC locus of the sample of cancer cells when compared to a control; and [0129] iv) determining whether the subject will benefit from being administered a NMT inhibitor in order to treat said cancer, wherein if the sample of cancer cells contains one or more structural alterations (e.g. chromosomal rearrangements, copy number gains and/or mutations) in the MYC locus, then the subject will benefit from being administered a NMT inhibitor, and if the sample of cancer cells does not contain one or more structural alterations (e.g. chromosomal rearrangements, copy number gains and/or mutations) in the MYC locus, then the subject will not benefit from being administered a NMT inhibitor.

[0130] In an embodiment, the one or more structural alterations are chromosomal rearrangements. Thus, suitably, step ii) of the above method involves analysing the cancer cells of step i) to check for the presence of one or more chromosomal rearrangements in the MYC locus. The person skilled in the art will be able to readily determine suitable techniques for checking for the presence of one or more chromosomal rearrangements in the MYC locus. One, non-limiting, example of a suitable technique for checking for the presence of one or more chromosomal rearrangements in the MYC locus is fluorescence in-situ hybridisation (FISH).

[0131] In another embodiment, the one or more structural alterations are mutations. Thus, suitably, step ii) of the above method involves analysing the cancer cells of step i) to check for the presence of one or more mutations in the MYC locus. The person skilled in the art will be able to readily determine suitable techniques for checking for the presence of one or more mutations in the MYC locus. One, non-limiting, example of a suitable technique for checking for the presence of one or more mutations in the MYC locus is gene sequencing.

[0132] Suitably, the control of step iii) is the structural arrangement of the MYC locus found in a normal, healthy cell, specifically, the control of step iii) is the chromosomal arrangement and/or genetic sequence found in the MYC locus of a normal, healthy cell.

[0133] It will be understood that the sample of cancer cells taken from said subject may be obtained by any suitable method known in the art. For instance, the sample of cancer cells taken from said subject may be those taken from a biopsy or may be a sample of circulating tumour cells (CTCs) taken from the subject.

[0134] According to a further aspect of the present invention, there is provided a method for determining whether a subject with a cancer will benefit from treatment with an NMT inhibitor, said method comprising the steps of: [0135] i) measuring the level of MYC expression in a sample of cancer cells taken from said subject; [0136] ii) comparing the level of MYC expression from step i) with a control; [0137] iii) determining whether the MYC expression in the sample of cancer cells is increased compared to the control; and [0138] iv) determining whether the subject will benefit from being administered a NMT inhibitor in order to treat said cancer, wherein if the MYC expression in the sample of cancer cells is higher than in the control, then the subject will benefit from being administered a NMT inhibitor, and if the MYC expression in the sample of cancer cells is not higher than in the control, then the subject will not benefit from being administered a NMT inhibitor.

[0139] It will be appreciated that the level of MYC expression in the sample of cancer cells may be determined by any suitable means known in the art. For example, the level of expression of MYC may be determined by measuring MYC protein levels. The MYC protein levels may be measured using any suitable technique known in the art, such as, for example, SDS-PAGE followed by Western blot using suitable antibodies raised against the target protein. In addition, or alternatively, the level of expression of MYC may be determined by measuring the level of mRNA. The level of mRNA may be measured using any suitable technique known in the art, such as, for example, northern blot or quantitative RT-PCR (qRT-PCR).

[0140] Suitably, the control of step ii) above is the MYC expression level found in a normal, healthy cell, for example, a normal, healthy cell of the same type as the cell being investigated. It will be understood that the MYC expression level found in a normal, healthy cell may also be determined using any of the techniques described in paragraph [0091] above.

[0141] According to a further aspect of the present invention, there is provided a method for the treatment of cancer in a subject who has been identified as benefiting from being administered a NMT inhibitor as determined by a method as described in any one of paragraphs [0085] to [0090] above, wherein said method comprises administering a therapeutically effective amount of a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof to the subject. Suitably, the NMT inhibitor may be any of the NMT inhibitors described hereinbelow.

Routes of Administration

[0142] The NMT inhibitors for use in the present invention may be administered to a subject by any convenient route of administration, whether systemically/peripherally or topically (i.e., at the site of desired action).

[0143] Routes of administration include, but are not limited to, oral (e.g, by ingestion); buccal; sublingual; transdermal (including, e.g., by a patch, plaster, etc.); transmucosal (including, e.g., by a patch, plaster, etc.); intranasal (e.g., by nasal spray); ocular (e.g., by eye drops); pulmonary (e.g., by inhalation or insufflation therapy using, e.g., via an aerosol, e.g., through the mouth or nose); rectal (e.g., by suppository or enema); vaginal (e.g., by pessary); parenteral, for example, by injection, including subcutaneous, intradermal, intramuscular, intravenous, intra-arterial, intracardiac, intrathecal, intraspinal, intracapsular, subcapsular, intraorbital, intraperitoneal, intratracheal, subcuticular, intraarticular, subarachnoid, and intrasternal; by implant of a depot or reservoir, for example, subcutaneously or intramuscularly. In certain embodiments, the NMT inhibitors for use in the present invention are administered to a subject by oral administration (e.g, by ingestion).

[0144] The amount of NMT inhibitor which is required to achieve a therapeutic effect will, of course, vary with the particular compound, the route of administration, the subject under treatment, including the type, species, age, weight, sex, and medical condition of the subject and the renal and hepatic function of the subject, and the particular disorder or disease being treated, as well as its severity. An ordinarily skilled physician, veterinarian or clinician can readily determine and prescribe the effective amount of the drug required to prevent, counter or arrest the progress of the condition.

[0145] An effective amount of the NMT inhibitor for use in the treatment of cancer as described herein is an amount sufficient to treat or prevent a cancer mentioned herein, slow its progression and/or reduce the symptoms associated with the cancer.

[0146] When orally administered to humans, the NMT inhibitor for use in the present invention will generally be administered at an amount of between about 0.01 mg per kg of body weight per day (mg/kg/day) to about 100 mg/kg/day, preferably 0.01 mg per kg of body weight per day (mg/kg/day) to 10 mg/kg/day, and most preferably 0.1 to 5.0 mg/kg/day, for adult humans.

[0147] The size of the dose for therapeutic or prophylactic purposes of a compound of the formula I will naturally vary according to the nature and severity of the conditions, the age and sex of the animal or patient and the route of administration, according to well-known principles of medicine.

[0148] In using a NMT inhibitor for the treatment of cancer it will generally be administered so that a daily dose in the range, for example, 0.1 mg/kg to 75 mg/kg body weight is received, given if required in divided doses. In general, lower doses will be administered when a parenteral route is employed. Thus, for example, for intravenous or intraperitoneal administration, a dose in the range, for example, 0.1 mg/kg to 30 mg/kg body weight will generally be used. Similarly, for administration by inhalation, a dose in the range, for example, 0.05 mg/kg to 25 mg/kg body weight will be used. Oral administration may also be suitable, particularly in tablet form. Typically, unit dosage forms will contain about 0.5 mg to 0.5 g of a NMT inhibitor for use in this invention.

Combination Therapies

[0149] The NMT inhibitor defined hereinbefore may be applied as a sole therapy or be administered in combination with one or more other therapeutic agents, or may be administered in combination with conventional surgery or radiotherapy.

[0150] Such conjoint treatment may be achieved by way of the simultaneous, sequential or separate dosing of the NMT inhibitor and the one or more other therapeutic agents of the treatment. Such combination products may employ the NMT inhibitors of this invention within any suitable dosage range, such as, for example, the dosage range described hereinabove, and the other pharmaceutically-active agent may be within its approved dosage range.

[0151] Thus, the present invention further provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in combination with one or more other therapeutic agents in the treatment of a MYC addicted cancer. Suitably, the MYC addicted cancer is any one of the MYC addicted cancers described hereinabove.

[0152] The present invention also provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in combination with one or more other therapeutic agents in the treatment of a MYC dysregulated cancer. Suitably, the MYC dysregulated cancer is any one of the MYC dysregulated cancers described hereinabove.

[0153] The present invention also provides a NMT inhibitor, or a pharmaceutically acceptable salt, solvate or hydrate thereof, for use in combination with one or more other therapeutic agents in the treatment of a cancer comprising one or more structural alterations of the MYC locus. Suitably, the cancer comprising one or more structural alterations of the MYC locus is any one of the cancers comprising one or more structural alterations of the MYC locus described hereinabove.

[0154] Suitable, but non-limiting, examples of other therapeutic agents which may be administered in combination with the NMT inhibitor include one or more other chemotherapeutic agents.

[0155] For example, the NMT inhibitor may be administered in addition to any currently recommended treatment (also known as the “standard of care”) for cancer.

N-Myristoyl Transferase (NMT) Inhibitors

[0156] N-myristoyl transferase (NMT) is a monomeric enzyme, which is ubiquitous in eukaryotes. NMT catalyses an irreversible co-translational transfer of myristic acid (a saturated 14-carbon fatty acid) from myristoyl-Coenzyme A (myr-CoA) to a protein substrate containing an N-terminal glycine with formation of an amide bond (Farazi, T. A., G. Waksman, and J. I. Gordon, J. Biol. Chem., 2001. 276(43): p. 39501-39504).

[0157] There are two types of human NMT, human NMT1 (HsNMT1) and human NMT2 (HsNMT2). Inhibition of human NMT has been suggested as a target for treating or preventing various diseases or disorders, for example hyperproliferative disorders (cancers, e.g. human colorectal cancer, gallbladder carcinoma, brain tumours, and lymphomas such as B-cell lymphoma) (Resh M D. 1993. Biochem. Biophys. Acta 1115, 307-22; Berthiaume L G, Beauchamp E, WO2017/011907). As NMT plays a key role in protein trafficking, mediation of protein-protein interactions, stabilization of protein structures and signal transduction in living systems, inhibition of the NMT enzyme has the potential to disrupt multi-protein pathways. This is an attractive characteristic to reduce the risk of the development of resistance in, for example, treatment or prevention of hyperproliferative disorders.

[0158] Compounds active as inhibitors of NMT have previously been disclosed, see for example WO00/37464 (Roche), WO2010/026365 (University of Dundee), WO2013/083991 (Imperial Innovations Limited) and WO2017/001812 (Imperial Innovations Limited), and their use in the treatment of cancer has been described.

[0159] Thus, the NMT inhibitors for use in the present invention are species (e.g. compounds) which display activity as inhibitors of N-myristoyl transferase (NMT). Furthermore, the term “NMT inhibitor” as used herein will be understood to cover any species which binds to NMT and inhibits its activity. The inhibitors may act as competitive inhibitors, or partial competitive inhibitors. The inhibitor may bind to NMT at the myr-CoA binding pocket or at the peptide binding pocket (or inhibit NMT through another mechanism). The NMT inhibitor of the present invention preferably bind and inhibit NMT through the peptide binding pocket.

[0160] Suitably, the NMT inhibitors for use in the present invention are compounds which display activity as inhibitors of N-myristoyl transferase (NMT). Suitable compounds which display activity as inhibitors of NMT are known in the art. Non-limiting examples of suitable NMT inhibitors are described in, for example, WO00/37464 (Roche), WO2010/026365 (University of Dundee), WO2013/083991 (Imperial Innovations Limited) and WO2017/001812 (Imperial Innovations Limited), the entire contents of which are incorporated herein by reference.

[0161] In a particular embodiment, the NMT inhibitor for use in the present invention is a compound of Formula I, Formula II or Formula III, as defined herein, or a pharmaceutically acceptable salt, solvate or hydrate thereof. For the avoidance of doubt, this embodiment of the present invention also encompasses all sub-formulae of Formula I, Formula II and Formula III described herein, such as for example, compounds of Formula (IA{circumflex over ( )}{circumflex over ( )}) and/or Formula IIa.

Other Possible NMT Inhibitors

[0378] Other suitable NMT inhibitors may include, for example, any one of the compounds displaying activity as an inhibitor of N-myristoyl transferase (NMT) described in WO00/37464 (Roche) or WO2013/083991 (Imperial Innovations Limited).

[0379] In certain embodiments, the NMT inhibitor is any one of the compounds displaying activity as an inhibitor of N-myristoyl transferase (NMT) described in WO2013/083991. It will be appreciated that this embodiment encompasses both generic and specific compounds described in WO2013/083991.

[0380] In a particular embodiment, the NMT inhibitor of the present invention is any one of compounds 1-140 disclosed in WO2013/083991.

[0381] Salts of the NMT inhibitors for use in the invention are those wherein a counter-ion is pharmaceutically acceptable. Suitable pharmaceutically acceptable salts according to the invention include those formed with organic or inorganic acids or bases. In particular, suitable salts formed with acids according to the invention include those formed with mineral acids, strong organic carboxylic acids, such as alkanecarboxylic acids of 1 to 4 carbon atoms which are unsubstituted or substituted, for example, by halogen, such as saturated or unsaturated dicarboxylic acids, such as hydroxycarboxylic acids, such as amino acids, or with organic sulfonic acids, such as (C.sub.1-C.sub.4)-alkyl- or aryl-sulfonic acids which are unsubstituted or substituted, for example by halogen. Pharmaceutically acceptable acid addition salts include those formed from hydrochloric, hydrobromic, sulphuric, nitric, citric, tartaric, acetic, phosphoric, lactic, pyruvic, acetic, trifluoroacetic, succinic, perchloric, fumaric, maleic, glycolic, lactic, salicylic, oxaloacetic, methanesulfonic, ethanesulfonic, p-toluenesulfonic, formic, benzoic, malonic, naphthalene-2-sulfonic, benzenesulfonic, isethionic, ascorbic, malic, phthalic, aspartic, and glutamic acids, lysine and arginine. For example, it may be the hydrochloric (HCl) salt.

[0382] Compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”. Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.

[0383] The NMT inhibitor may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)-stereoisomers or as mixtures thereof. It is to be understood that the NMT inhibitors for use in the present invention encompasses all optical, diastereoisomers and geometric isomers and mixtures thereof that possess NMT inhibition activity.

[0384] The present invention also encompasses NMT inhibitors as defined herein which comprise one or more isotopic substitutions. For example, H may be in any isotopic form, including 1H, 2H(D), and 3H (T); C may be in any isotopic form, including 12C, 13C, and 14C; and O may be in any isotopic form, including 160 and 180; and the like.

[0385] Those skilled in the art of organic chemistry will appreciate that many organic compounds can form complexes with solvents in which they are reacted or from which they are precipitated or crystallized. These complexes are known as “solvates”. For example, a complex with water is known as a “hydrate”. Solvates, such as hydrates, exist when the drug substance incorporates solvent, such as water, in the crystal lattice in either stoichiometric or non-stoichiometric amounts. Drug substances are routinely screened for the existence of hydrates since these may be encountered at any stage of the drug manufacturing process or upon storage of the drug substance or dosage form. Solvates are described in S. Byrn et al., Pharmaceutical Research, 1995. 12(7): p. 954-954, and Water-Insoluble Drug Formulation, 2.sup.nd ed. R. Liu, CRC Press, page 553, which are incorporated herein by reference. Accordingly, it will be understood by the skilled person that the NMT inhibitors for use in the present invention may be present in the form of solvates, wherein the associated solvent is a pharmaceutically acceptable solvent. For example, a hydrate is an example of a pharmaceutically acceptable solvate.

[0386] It is also to be understood that the NMT inhibitors may exhibit polymorphism, and that the invention encompasses all such forms that possess the herein described activity.

[0387] The NMT inhibitors for use in the present invention may also exist in a number of different tautomeric forms and references to NMT inhibitors for use in the present invention include all such forms. For the avoidance of doubt, where a compound can exist in one of several tautomeric forms, and only one is specifically described or shown, all others are nevertheless embraced. Examples of tautomeric forms include keto-, enol-, and enolate-forms, as in, for example, the following tautomeric pairs: keto/enol (illustrated below), imine/enamine, amide/imino alcohol, amidine/amidine, nitroso/oxime, thioketone/enethiol, and nitro/aci-nitro.

##STR00077##

[0388] The NMT inhibitor for use in the present invention may be administered in the form of a pro-drug which is broken down in the human or animal body to release the NMT inhibitor for use in the present invention. A pro-drug may be used to alter the physical properties and/or the pharmacokinetic properties of the NMT inhibitor. A pro-drug can be formed when the NMT inhibitor contains a suitable group or substituent to which a property-modifying group can be attached. Examples of pro-drugs include in vivo cleavable ester derivatives that may be formed at a carboxy group or a hydroxy group in an NMT inhibitor for use in the present invention, and in-vivo cleavable amide derivatives that may be formed at a carboxy group or an amino group in an NMT inhibitor for use in the present invention.

[0389] For example, the NMT inhibitors for use in the present invention may have an appropriate group which may be converted to an amide or a carbamate. Typical amide and carbamate groups formed from a basic nitrogen in the NMT inhibitors of the present invention, for example, the compounds of Formula (I), include >NR.sup.GC(O)R.sup.G, >NR.sup.GCO.sub.2R.sup.G, and >NR.sup.GSO.sub.2R.sup.G, where R.sup.G is selected from the group consisting of C.sub.1-6alkyl, C.sub.2-8alkenyl, C.sub.2-8alkynyl, C.sub.3-8cycloalkyl and C.sub.3-8cycloalkylC.sub.1-8alkyl, haloC.sub.1-8alkyl, dihaloC.sub.1-8alkyl, trihaloC.sub.1-8alkyl, phenyl and phenylC.sub.1-4alkyl; more preferably R.sup.G is selected from the group consisting of C.sub.1-6alkyl, C.sub.2-6alkenyl, C.sub.2-6alkynyl, C.sub.3-8cycloalkyl and C.sub.3-8cycloalkylC.sub.1-8alkyl

Biological Data

Materials

Cell Lines

P-493-6

[0625] The P-493-6 cell line is a non-transformed B cell line that can be genetically engineered to have either “low” levels of c-Myc, “medium” levels of c-Myc or “high” levels of c-Myc. The terms “low”, “medium” and “high” are descriptors commonly used in the art and will be readily understood to mean: [0626] i) “low” levels of c-Myc—a level of MYC expression which represents non-proliferating normal cells (i.e. a level of MYC expression not sufficient to cause the cycling of the cells); [0627] ii) “medium” levels of c-Myc—a level of MYC expression which represents normal proliferating cells; and [0628] iii) ““high” levels of c-Myc—a level of MYC expression which represents enforced/deregulated expression of c-Myc, typically observed in cancerous cells.

[0629] The P-493-6 cell lines were sourced from Chi Van Dang, Ludwig Cancer Research. The modified P-493-6 cell lines may be established using methodology well known in the art, see for example Int. J. Cancer, 2000, 87(6), 787-793.

SKNAS and Shep

[0630] The SKNAS and Shep cell lines are both human neuroblastoma cell lines. The SKNAS cell line used herein was sourced from Linda Valentijn, Academic Medical Center, Amsterdam. The Shep cell line used herein was sourced from Michael D. Hogarty, The Children's Hospital of Philadelphia. The SKNAS and Shep cell lines used herein may be prepared using methods known in the art, see, for example, Cancer Res., 2005, 65(8), 3136-3145 and Oncogene, 2008, 27(24), 3424-3434 respectively.

[0631] In the experimental protocols described herein the SKNAS and Shep cell lines were genetically engineered to model differences between high grade neuroblastoma (which are usually marked by MYCN amplifications and with particular poor clinical prognosis) and low grade neuroblastoma. Accordingly, the SKNAS and/or Shep cell lines “with N-MYC induction” described herein will be understood to be cell lines treated with tamoxifen and represent aggressive, high grade type cancer cells. Conversely, the SKNAS and/or Shep cell lines “without N-MYC induction” described herein will be understood to be cell lines not treated with tamoxifen and represent less aggressive forms of cancer cells (Huang et al., Cold Spring Harb. Perspect. Med., 2013, 3(10), 1-22).

The analysis was performed on biological replicates for each condition on biological replicates generating approximately 30 million 100 bp paired-end reads. The RSEM package (v1.3.0) (Li and Dewy, BMC Bioinformatics, 2011) and STAR (v2.5.2a) (Dobin et. al., Bioinformatics, 2013) were used to align reads to the human hg38 transcriptome, taken from Ensembl (v. GRChg38) available at UCSC (http://hqdownload.soe.ucsc.edu/downloads.html). For RSEM, all parameters were run as default using the “-forward-prob 0” option for strand specific protocol. Differential expression analysis was carried out with DESeq2 (v1.12.4) (Love, et. al., Genome Biol, 2014) within R (v3.3.1).

[0644] The experiment was performed in T-25 flasks in biological quadruplicate. On day 0, 500,000 cells/mL were seeded in 10 mL of media. On day 1,100 nM of Compound 2 or DMSO as control were added. On day 2 (24 hours of incubation), the RNA was purified with the miRNeasy kit, according to manufacturer's instructions.

HeLa

[0645] The experiment was performed in 10 cm.sup.2 dishes, in biological quadruplicate. On day 0, 1,000,000 cells/dish were plated in 10 mL of media. On day 1, 100 nM of Compound 2 or DMSO as control were added. On day 2 (24 hours of incubation), the RNA was purified with the miRNeasy kit, according to manufacturer's instructions.

Gene Set Enrichment Analysis

[0646] Gene set enrichment analysis (GSEA) was performed using GSEA (v3.0) (Subramanian et. al., PNAS, 2005, 102(43), 15545-15550). Gene sets were obtained from the Broad Institute Signatures data base (http://software.broadinstitute.org/gsea/msigdb/index.jsp). For the in-house RNAseq data, GSEA was carried out with ranked gene lists, using Wald statistics. All parameters were kept as default, except for the enrichment statistic (classic) and the max size that was changed to 500.000 respectively. For the microarray data, the pre-processed data was obtained from the Sanger Institute (Lorio et al., Cell, 2016, 166(3), 740-754; https://www.cancerrxgene.org/downloads). All parameters were kept as default, except the max size that was changed to 500,000 respectively. For the RNAseq data and CRISPR data sets from the Broad Institute, the pre-processed data was obtained from the DepMap project (CCLE and GDSC Consortium, Nature, 2015, 528, 84-87 and Robin et. al., Nature Genetics, 2017, 49(12), 1779-1784; https://depmap.org/portal/download/; Public 18Q4 Versions). All parameters in the GSEA were kept to default, except the max size that was changed to 500.000 respectively.

Pharmacogenomics Screens

[0647] The sensitivity data, measured as EC50, for cancer cell lines treated with Compound 4, Compound 3, and Compound 6 were provided by the Sanger Institute, using their methods described in Lorio et. al., Cell, 2016,166(3), 740-754. The sensitivity data, measured as EC50, on Compound 3 and Compound 4 is not yet published; the sensitivity data for Compound 6 is available on: https://www.cancerrxgene.org/translation/Drug/1266. For the microarray data, copy number data, recurrently altered chromosomal segments data, and genomic variants, used to compare the expression of different genes or the presence/absence of structural alterations in the Myc paralogs loci with sensitivity, the pre-processed data was obtained from the Sanger Institute (https://www.cancerrxgene.org/downloads).

Results

NMT Inhibition

[0648] The NMT inhibition activity data for Compounds 1, 2, 3 and 4 is described in WO2017/001812. In particular, the NMT inhibition data is provided in Table 1 of WO2017/001812.

[0649] The inhibition activity data for Compound 6 is described in WO2010/026365, more specifically in the Table on page 118 of WO2010/026365.

Compounds 5 and 7

Example (a); HsNMT1 IC.SUB.50

[0650] The IC.sub.50 values for human NMT1 (HsNMT1) of Compounds 5 and 7 were measured using a sensitive fluorescence-based assay based on detection of CoA by 7-diethylamino-3-(4-maleimido-phenyl)-4-methylcoumarin, as described in Goncalves, V., et al., Analytical Biochemistry, 2012, 421, 342-344 and Goncalves, V., et al., J. Med. Chem, 2012, 55, 3578.

[0651] The HsNMT1 IC.sub.50 value for Compound 5 was observed to be 1.5 nM.

[0652] The HsNMT1 IC.sub.50 value for Compound 7 was observed to be 0.4 nM.

Example (b) Metabolic Activity Assay (MTS Assay)

[0653] Compounds 5 and 7 were also tested for activity in an in vitro metabolic activity assay using the human cell line MRC5. Compounds having activity in inhibiting metabolic activity in the assay are expected to be useful as agents for preventing and/or treating cancer, by virtue of being inhibitors of human NMT1 and/or NMT2. The compounds with the highest activity in the assay are expected to be the most potent inhibitors of human NMT1 and/or NMT2.

Cell Preparation

[0654] MRC5 cells (cell type: fibroblast cells) were grown in DMEM media (supplemented with 10% FBS) and were seeded in a 96-well plate, 24 h prior to treatment. Cell suspensions were prepared by adjusting the cell density to the appropriate concentration (as stated in the Table 1 below) and 50 μL of the cell suspension was transferred to wells B-G in columns 2-11 of a 96-well plate.

TABLE-US-00001 TABLE 1 Number of cells plated MRC5 Cell suspension 38,000 concentration (cells/mL) cells per well 1,900

Assay Procedure

[0655] 100 μL of growth media (DMEM media) containing 0.2% DMSO was added to wells B-G in columns 2 and 11 as positive controls, and 100 μL of growth media containing Puromycin (3 μg/mL; final concentration in the plate 2 μg/mL) was added to wells B-G in column 3 as a negative control. Seven concentrations of NMT inhibitor stock solution were prepared for Compound 5 (same final percentage of DMSO, dilution factor=3 starting from 15 μM or 150 μM). 100 μL of inhibitor stock solution was added to wells B-G in columns 4-10 of a 96-well plate (final concentration of Compound 5 in the plate starting from 10 μM or 100 μM; total volume in each well was 150 μL). The plate was incubated at 37° C. with 5% CO.sub.2 level.

[0656] After 72 h, 20 μL MTS reagent (Promega, prepared according to the supplier protocol) was added to each well of the 96-well plate. The plate was incubated at 37° C. for 2 h and the absorbance per well was measured at 490 nm with an EnVision plate reader. The average absorbance value of the negative control (Puromycin-treated cells) was subtracted from each value and the metabolic activity was calculated as a percentage relative to the positive control (DMSO-treated cells). EC50 values were calculated using GraphPad.

[0657] The EC.sub.50 value for Compound 5 was observed to be 13 nM.

[0658] The EC.sub.50 value for Compound 7 was observed to be 37 nM.

Correlations Between Alterations in MYC and the Effectiveness of a NMT Inhibitor

P-493-6 Cell Lines

Validation of the P-493-6 Cell Lines

[0659] FIGS. 1, 2 and 3 show the flow cytometry analysis for the expression of c-MYC in the P-493-6 cell line. This data shows that the genetically engineered P-493-6 cell lines (immortalised B cell lines with an inducible system) allow for three different MYC levels: high, medium and low (as defined above). This makes the P-493-6 cell line a particularly good cell line to use for determining the correlation between the effectiveness of an NMT inhibitor and MYC expression.

[0660] High levels of MYC expression was found to cause increased cell size, which was measured and determined by increased forward scatter.

[0661] FIG. 1 shows: a) representative flow cytometry analysis for the expression of the c-Myc in the P-493-6 cell line from an unstained control (first row), low levels of c-Myc (second row), medium levels of c-Myc (third row), and high levels of c-Myc (fourth row); b) quantification of the median fluorescence intensities (MFI), normalised against the unstained control of the expression levels of c-Myc (N=3); c) representative flow cytometry analysis for the forward scatter area (FSC-A) as a surrogate for cell size in the P-493-6 cell line from low levels of c-Myc (first row), medium levels of c-Myc (second row), and high levels of c-Myc (third row); and d) quantification of the FSC-A geometric mean (N=3).

[0662] FIG. 2 shows: a) representative flow cytometry analysis of EdU incorporation, clicked to an AlexaFluor488fluorochrom, in the c-Myc high P-493-6 cell line; b) representative flow cytometry analysis of EdU incorporation, clicked to an AlexaFluor 488 fluorochrom, in the c-Myc medium P-493-6 cell line; and c) representative flow cytometry analysis of EdU incorporation, clicked to an AlexaFluor 488 fluorochrom, in the c-Myc low P-493-6 cell line.

[0663] FIG. 3 shows: a) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis (N=3); b) quantification of the cell number in 100 uL of cell suspension, analysed via flow cytometry after 72 hours of induction (N=3).

[0664] While there is little difference between DNA synthesis between the P-493-6 cell lines with high, medium or low MYC levels (as measured by EdU incorporation), overall, the cell numbers were found to be higher in the MYC high state P-496-6 cell lines, indicating a potentially faster cycling.

MYC Synthetic Lethality Data

[0665] FIG. 4 shows: a) metabolic viability of the P-493-6 cell line treated with Compound 2 at the shown concentrations for 48 hours, with different expression levels of c-Myc induced; b) metabolic viability of the P-493-6 cell line treated with Compound 2 at the shown concentrations for 72 hours, with different expression levels of c-Myc induced.

[0666] From FIG. 4 it can be seen that at both 48 hours and 72 hours there is a clear MYC-dependent increase in cell death in the P-493-6 cell lines. This data suggests that high levels of c-MYC are lethal in combination with an NMT inhibitor, such as Compound 2, and even administering the NMT inhibitor at a concentration as low as 10 nM resulted in measurable effects on cell viability at 72 hours in the Myc high cell lines.

[0667] FIG. 5 shows: a) metabolic viability of the P-493-6 cell line treated with Compound 6 at the shown concentrations for 72 hours, with different expression levels of c-Myc induced; b) metabolic viability of the P-493-6 cell line treated with Compound 5 at the shown concentrations for 72 hours, with different expression levels of c-Myc induced; and c) metabolic viability of the P-493-6 cell line treated with Compound 1 at the shown concentrations for 72 hours, with different expression levels of c-Myc induced.

[0668] FIG. 5 shows that the MYC-dependent increase in cell death in the P-493-6 cell lines is observed for a range of structurally diverse NMT inhibitor compounds. With the highest levels of cell death being recorded in each case for P-493-6 cell lines with high MYC expression.

Quantification of Cell Numbers

[0669] FIG. 6 shows: a) quantification of the cell numbers (excluding dead cells) of the P-493-6 cell line with c-MYC high, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); b) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the P-493-6 cell line with c-MYC high, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); c) quantification of the relative proportion of cells that are Zombie NIR negative, hence have intact cell membranes, of the P-493-6 cell line with c-MYC high, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); and d) quantification of the relative proportion of cells that are either dead (Zombie NIR positive), undergoing apoptosis (Caspase3 positive) or viable (Zombie NIR negative and Caspase 3 negative) of the P-493-6 cell line with c-Myc high (N=2).

[0670] FIG. 7 shows: a) quantification of the cell numbers (excluding dead cells) of the P-493-6 cell line with c-MYC medium, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); b) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the P-493-6 cell line with c-MYC medium, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); c) quantification of the relative proportion of cells that are Zombie NIR negative, hence have intact cell membranes, of the P-493-6 cell line with c-MYC medium, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); and d) quantification of the relative proportion of cells that are either dead (Zombie NIR positive), undergoing apoptosis (Caspase3 positive) or viable (Zombie NIR negative and Caspase 3 negative) of the P-493-6 cell line with c-Myc medium.

[0671] FIG. 8 shows: a) quantification of the cell numbers (excluding dead cells) of the P-493-6 cell line with c-MYC low, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); b) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the P-493-6 cell line with c-MYC low, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); and c) quantification of the relative proportion of cells that are Zombie NIR negative, hence have intact cell membranes, of the P-493-6 cell line with c-MYC low, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); and d) quantification of the relative proportion of cells that are either dead (Zombie NIR positive), undergoing apoptosis (Caspase3 positive) or viable (Zombie NIR negative and Caspase 3 negative) of the P-493-6 cell line with c-Myc low.

[0672] FIGS. 6, 7 and 8 show that high levels of c-MYC, in combination with an NMT inhibitor, cause rapid depletion of the cells. It can be seen from FIGS. 6, 7 and 8 that the MYC high cells are being depleted faster than the MYC medium and MYC low cells, with a rapid drop in overall cell viability. Interestingly, DNA synthesis in relative terms is less affected than in the MYC medium case. The MYC low cells are relatively unaffected by the administration of the NMT inhibitor compound.

Shea ER-N-MYC and SKNAS ER-N-MYC Cell Lines

Validation of the Shep ER-N-MYC and SKNAS ER-N-MYC Cell Lines

[0673] SKNAS and Shep are neuroblastoma cell lines, which usually have little to no MYCN expression. Upon treatment with tamoxifen, the cell line induces MYCN which increases cycling (seen in the top trace of FIGS. 11 and 12 measured by increase in S phase) and protein synthesis (seen in FIG. 13 and measured by OPP incorporation).

[0674] FIG. 10 shows representative western blot showing MYCN protein expression following time course treatment with 100 nM of Tamoxifen. GAPDH was used as loading control.

[0675] FIG. 11 shows: a) representative flow cytometric analysis of the cell cycle profile for the Shep ER-N-MYC cell line, without induction of MYCN. Cells in G1/0 phase have low amounts of FxCycle Violet stainings and are EdU negative. Cells in S phase are EdU positive. Cells in G2/M phase have high amounts of FxCycle Violet staining and are EdU negative; b) representative flow cytometric analysis of the cell cycle profile for the Shep ER-N-MYC cell line, with induction of MYCN. Cells in G1/0 phase have low amounts of FxCycle Violet stainings and are EdU negative. Cells in S pase are EdU positive. Cells in G2/M phase have high amounts of FxCycle Violet staining and are EdU negative; and c) quantification of the cell cycle profile of the Shep cell, with and without the induction of MYCN (N=3).

[0676] FIG. 12 shows: a) representative flow cytometric analysis of the cell cycle profile for the SKNAS ER-N-MYC cell line, without induction of MYCN. Cells in G1/0 phase have low amounts of FxCycle Violet stainings and are EdU negative. Cells in S pase are EdU positive. Cells in G2/M phase have high amounts of FxCycle Violet staining and are EdU negative; b) representative flow cytometric analysis of the cell cycle profile for the SKNAS ER-N-MYC cell line, with induction of MYCN. Cells in G1/0 phase have low amounts of FxCycle Violet stainings and are EdU negative. Cells in S pase are EdU positive. Cells in G2/M phase have high amounts of FxCycle Violet staining and are EdU negative; and c) quantification of the cell cycle profile of the SKNAS ER-N-MYC cell, with and without the induction of MYCN (N=3).

[0677] FIG. 13 shows: a) representative flow cytometric analysis of the protein synthesis, via incorporation of OPP, of the Shep ER-N-MYC cell line with or without induction of MYCN; first row: with induction of MYCN; second row: without induction of MYCN; last row: no OPP added; b) quantification of the median fluorescence of OPP, clicked to the AF488 fluorochrome, of the Shep ER-N-MYC cell line with and without induction of N-Myc; c) representative flow cytometric analysis of the protein synthesis, via incorporation of OPP, of the SKNAS ER-N-MYC cell line with or without induction of MYCN, first row: with induction of MYCN; second row: without induction of MYCN, last row: no OPP added; d.) quantification of the median fluorescence of OPP, clicked to the AF488 fluorochrome, of the SKNAS ER-N-MYC cell line with and without induction of MYCN.

MYC Synthetic Lethality Data

[0678] Similar to the case of c-MYC in the P-493-6 cell lines, it can be seen from FIGS. 14 and 15 that high levels of MYCN induce increased cell death more rapidly at lower concentrations upon treatment with Compound 2 than for low levels of MYCN. Similar results are observed when the Compounds 1 and 6 are administered to the Shep-ER-N-MYC and SKNAS-ER-N-MYC cell lines (see FIGS. 14 and 15).

[0679] FIG. 14 shows: a) metabolic viability of the Shep-ER-N-MYC cell line treated with Compound 6 at the shown concentrations for 72 hours, with (grey) or without (black) induction of MYCN; b) metabolic viability of the Shep-ER-N-MYC cell line treated with Compound 2 at the shown concentrations for 72 hours, with (grey) or without (black) induction of MYCN, c) metabolic viability of the SKNAS-ER-N-MYC cell line treated with Compound 1 at the shown concentrations for 72 hours, with (orange) or without (grey) induction of MYCN.

[0680] FIG. 15 shows the metabolic viability of the SKNAS-ER-N-MYC cell line treated with: a) Compound 6; b) Compound 2; and c) Compound 1 at the shown concentrations for 96 hours, with (grey) or without (black) induction of MYCN.

Quantification of Cell Numbers

[0681] As can be seen from FIGS. 16 and 18, administration of a NMT inhibitor to a neuroblastoma cell with high levels of MYCN results in rapid depletion of the cells. For the Shep cell line in the high MYCN state, apoptosis induction occurs rapidly after 24 hours (up to 60%). In the case of no (or low) MYCN, this only occurs after 48 hours and to a much lesser degree. As similarly observed for c-MYC expression in the P-493-6 cell line, the Shep cells are still trying to cycle at 48 hours with high MYCN. (See FIG. 17) Similar results are observed for the SKNAS ER-N-MYC cell line (FIGS. 18 and 19).

[0682] FIG. 16 shows: a) quantification of the cell numbers (excluding dead cells) of the Shep-ER-N-MYC cell line without MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); b) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the Shep-ER-N-MYC cell line without MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); c) quantification of the relative proportion of cells that caspase3 positive, hence are undergoing apoptosis, of the Shep-ER-N-MYC cell line without MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2). d) quantification of the cell numbers (excluding dead cells) of the Shep-ER-N-MYC cell line with MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); e) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the Shep-ER-N-MYC cell line with MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); and f) quantification of the relative proportion of cells that caspase3 positive, hence are undergoing apoptosis, of the Shep-ER-N-MYC cell line with MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2).

[0683] FIG. 17 shows: a.) quantification of the cell cycle profile of the Shep-ER-N-Myc cell line without induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 48 hours (N=2); b.) quantification of the cell cycle profile of the Shep-ER-N-Myc cell line without induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 72 hours (N=2); c.) quantification of the cell cycle profile of the Shep-ER-N-Myc cell line with induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 48 hours (N=2); and d.) quantification of the cell cycle profile of the Shep-ER-N-Myc cell line with induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 72 hours (N=2).

[0684] FIG. 18 shows: a) quantification of the cell numbers (excluding dead cells) of the SKNAS-ER-N-MYC cell line without MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); b) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the SKNAS-ER-N-MYC cell line without MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, nM and control) of Compound 2 (N=2); c) quantification of the relative proportion of cells that caspase3 positive, hence are undergoing apoptosis, of the SKNAS-ER-N-MYC cell line without MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2). d) quantification of the cell numbers (excluding dead cells) of the SKNAS-ER-N-MYC cell line with MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); e) quantification of the relative proportion of cells that are EdU positive, hence engaging in DNA synthesis, of the SKNAS-ER-N-MYC cell line with MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2); and f) quantification of the relative proportion of cells that caspase3 positive, hence are undergoing apoptosis, of the Shep-ER-N-MYC cell line with MYCN induction, at the given time points (6, 24, 48 and 72 hours) with the shown concentrations (1 uM, 100 nM, 10 nM and control) of Compound 2 (N=2). FIG. 19 shows: a) quantification of the cell cycle profile of the Shep-ER-N-Myc cell line with induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 48 hours (left) and 72 hours (right) (N=2); and b) relative change of the different cell cycle phases, shown as log 2-fold changes over the control for 100 nM Compound 2 at 48 hours and 72 hours for the Shep-ER-N-Myc cell line with induction of MYCN.

[0685] FIG. 19 shows: a.) quantification of the cell cycle profile of the SKNAS-ER-N-Myc cell line without induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 48 hours (N=2); b.) quantification of the cell cycle profile of the SKNAS-ER-N-Myc cell line without induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 72 hours (N=2); c.) quantification of the cell cycle profile of the SKNAS-ER-N-Myc cell line with induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 48 hours (N=2); and d.) quantification of the cell cycle profile of the SKNAS-ER-N-Myc cell line with induction of MYCN, treated with the shown concentration of Compound 2 (1 uM, 100 nM, 10 nM and control) for 72 hours (N=2).

[0686] As can be seen from FIGS. 17 and 19, and as was similarly observed for c-MYC, MYCN forces the cells through the G1-S checkpoint increasing the lethality of the NMT inhibitor.

[0687] Furthermore, it was observed that the MYCN activated cells do not reduce their cycling even when presented with Compound 2 (see FIGS. 17 and 19), although there is a slight increase in G2/M accumulation. On the other hand, the cell line without activated MYCN was observed to stops cycling at 48 hours.

Global Correlations

[0688] The GDSC data shown in FIGS. 20-22 indicates a correlation between c-MYC expression and sensitivity to an NMT inhibitor. A trend was observed indicating that increased c-MYC correlates well with higher sensitivity to the three different NMT inhibitors tested in the Sanger cancer line drug screen. Contrary to previous disclosures in the art (see, for example, WO2017/011907A1), FIG. 23 shows that there is no correlation between the expression of hsNMT1 or hsNMT2 with the sensitivity to an NMT inhibitor.

mRNAseq Data

[0693] Looking at the mRNAseq data sets for BL41 and HeLa (FIGS. 24 and 25), in particular the case of BL41, it is observed that the c-MYC gene sets collapse to a much greater extent than in HeLa. This potentially indicates that the c-MYC driven program is particularly disturbed in BL41, a Burkitt's cell line with c-MYC translocations. Thus, the mRNAseq in BL41 indicates an increased breakdown of the MYC transcriptional program upon administration of a NMT inhibitor compound in a c-MYC addicted cancer.

Structural Alterations of the MYC/MYCN/MYCL Loci

[0696] As can be seen in FIG. 26, structural alteration of MYC/MYCN/MYCL loci render cells more sensitive to the NMT inhibitor compound. As can be seen in FIG. 27, those structural alterations correlate with increased activation of different MYC gene sets.

[0697] Across the three tested cancer cell line screens, it was observed that cell lines that have structural alterations (that is: copy number gains and/or chromosomal rearrangements and/or mutations in c-MYC/MYCN/MYCL) are more sensitive to an NMT inhibitor than cell lines without such structural alterations. In two of these screens the correlation is statistically significant and in the other screen a strong trend is observed.

[0698] FIG. 26 shows: a.) the effect of the presence of structural alterations (that is: copy number gains and/or chromosomal rearrangements and/or mutations in c-MYC/MYCN/MYCL) on the sensitivity to the NMT inhibitor Compound 4 (a nonparametric Mann Whitney test was used); b.) the effect of the presence of structural alterations (that is: copy number gains and/or chromosomal rearrangements and/or mutations in c-MYC/MYCN/MYCL) on the sensitivity to the NMT inhibitor Compound 3 (a nonparametric Mann Whitney test was used); and c.) the effect of the presence of structural alterations (that is: copy number gains and/or chromosomal rearrangements and/or mutations in c-MYC/MYCN/MYCL) on the sensitivity to the NMT inhibitor Compound 6 (a nonparametric Mann Whitney test was used).

‘Sensitive to NMTi’ Gene Set and its Appliance to MYC Driven Cancers

[0700] As can be seen in FIG. 28, the sensitivity to the NMT inhibitor Compound 4 can be pinpointed to certain key biological functions via GSEA: translation, transcription, protein degradation and nuclear trafficking, which are nuclear pore genes.

[0701] As can be seen in FIG. 29, a leading edge analysis of the top gene sets being enriched in the sensitive cancer cell lines to the NMT inhibitor Compound 4 yields in a “Sensitive to NMTi’ gene set, that contains 137 genes. This gene set is strongly enriched in the sensitive cancer cell lines to the NMT inhibitors Compound 3, Compound 4 and Compound 6, showing its predictive value. Additionally, as can be seen in FIG. 30, the ‘Sensitive to NMTi’ gene set is also enriched in cancer cell lines that are more dependent on NMT1 in a gene knock out essentiality screen. Importantly, the gene set ‘Sensitive to NMTi’ is also enriched in cells with high c-Myc expression and cancer cell lines with structural alterations in the MYC loci.

[0702] FIG. 28 shows: a.) the workflow to identify biological functions that correlate with resistance or sensitivity to the NMT inhibitor Compound 4.1. The cancer cell line screen was divided in the quartiles of the most resistant and the most responsive cell lines; II. The cell lines were matched to the expression data, obtained from Lorio et. al., Cell, 2016, 166(3), 740-754; III. GSEA was performed with the curated gene sets (C2; obtained from the Broad Institute: http://software.broadinstitute.org/gsea/index.jsp): and b.) the Top 5 gene sets by normalised enrichment score (NES), correlating with sensitivity to the NMT inhibitor Compound 4, were identified as being enriched with genes that are involved in translation, viral infection gene sets (containing genes involved in translation, transcription and protein degradation) and mRNA processing.

[0703] FIG. 29 shows: a.) the workflow to define a new gene set ‘Sensitive to NMTi’, based on the data with the NMT inhibitor Compound 4. I. The top 10 gene sets, correlating with sensitivity to the NMT inhibitor Compound 4 were used for a leading edge analysis; II. The leading edge analysis allows for the identification of driver genes in each gene set (that is: genes that cause strong enrichment of the respective gene set); III. The leading edge analysis yielded in 137 genes that were used to define a new gene set ‘Sensitive to NMTi’; IV. The newly defined gene set was applied to the screens with the NMT inhibitors Compound 1 and Compound 3 to validate the gene set; b.) The gene set ‘Sensitive to NMTi’ was applied to the cancer cell screen with the NMT inhibitor Compound 4 and shows as expected strong enrichment in the sensitive cell lines; and c.) The gene set ‘Sensitive to NMTi’ was applied to the cancer cell line screens with the NMT inhibitors Compound 3 (left) and Compound 6 (right), and shows for both NMT inhibitors strong enrichment in the sensitive cell lines respectively.

[0704] FIG. 30 shows: a.) the application of the ‘Sensitive to NMTi’ gene set to the CRISPR essentiality screening, conducted by the Broad Institute. I. The DepMap CRISPR essentiality scores were obtained from the Broad Institute (Robin, Nat Genetics, 2017, 49(12), 1779-1784; the Q4 2018 data sets are available here: https://depmap.org/portal/download/), and the cancer cell lines were divided into cell lines with high essentiality of NMT1 and low essentiality of NMT1, according to their CERES scores; II. The cell lines were matched to the RNAseq data from the Broad Institute (CCLE and GDSC Consortium, Nature, 2015, 528, 84-87; the Q4 2018 data sets are available here: https://depmap.org/portal/download/); III. The gene set ‘Sensitive to NMTi’ was applied to the data, showing enrichment in the cells with high essentiality of NMT1; b.) the ‘Sensitive to NMTi’ gene set was applied to compare cancer cell lines with high and low expression of c-MYC showing strong enrichment in the cells with high c-MYC expression; and c.) the ‘Sensitive to NMTi’ gene set was applied to compare cancer cell lines with and without structural alterations in the MYC loci, showing strong enrichment in the cancer cell lines with structural alterations in the MYC loci.
