[0258] In some embodiments, the compound, or pharmaceutically acceptable salt thereof, has the structure of any one of compounds 1-330 in Table 1.

[0259] Other embodiments, as well as exemplary methods for the synthesis of production of these compounds, are described herein.

Pharmaceutical Uses

[0260] The compounds described herein are useful in the methods of the invention and, while not bound by theory, are believed to exert their ability to modulate the level, status, and/or activity of a BAF complex, i.e., by inhibiting the activity of the BRG1 and/or BRM proteins within the BAF complex in a mammal. BAF complex-related disorders include, but are not limited to, BRG1 loss of function mutation-related disorders.

[0261] An aspect of the present invention relates to methods of treating disorders related to BRG1 loss of function mutations such as cancer (e.g., non-small cell lung cancer, colorectal cancer, bladder cancer, cancer of unknown primary, glioma, breast cancer, melanoma, non-melanoma skin cancer, endometrial cancer, or penile cancer) in a subject in need thereof. In some embodiments, the compound is administered in an amount and for a time effective to result in one or more (e.g., two or more, three or more, four or more) of: (a) reduced tumor size, (b) reduced rate of tumor growth, (c) increased tumor cell death (d) reduced tumor progression, (e) reduced number of metastases, (f) reduced rate of metastasis, (g) decreased tumor recurrence (h) increased survival of subject, (i) increased progression free survival of subject.

[0262] Treating cancer can result in a reduction in size or volume of a tumor. For example, after treatment, tumor size is reduced by 5% or greater (e.g., 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or greater) relative to its size prior to treatment. Size of a tumor may be measured by any reproducible means of measurement. For example, the size of a tumor may be measured as a diameter of the tumor.

[0263] Treating cancer may further result in a decrease in number of tumors. For example, after treatment, tumor number is reduced by 5% or greater (e.g., 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or greater) relative to number prior to treatment. Number of tumors may be measured by any reproducible means of measurement, e.g., the number of tumors may be measured by counting tumors visible to the naked eye or at a specified magnification (e.g., 2×, 3×, 4×, 5×, 10×, or 50×).

[0264] Treating cancer can result in a decrease in number of metastatic nodules in other tissues or organs distant from the primary tumor site. For example, after treatment, the number of metastatic nodules is reduced by 5% or greater (e.g., 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% or greater) relative to number prior to treatment. The number of metastatic nodules may be measured by any reproducible means of measurement. For example, the number of metastatic nodules may be measured by counting metastatic nodules visible to the naked eye or at a specified magnification (e.g., 2×, 10×, or 50×).

[0265] Treating cancer can result in an increase in average survival time of a population of subjects treated according to the present invention in comparison to a population of untreated subjects. For example, the average survival time is increased by more than 30 days (more than 60 days, 90 days, or 120 days). An increase in average survival time of a population may be measured by any reproducible means. An increase in average survival time of a population may be measured, for example, by calculating for a population the average length of survival following initiation of treatment with the compound of the invention. An increase in average survival time of a population may also be measured, for example, by calculating for a population the average length of survival following completion of a first round of treatment with a pharmaceutically acceptable salt of the invention.

[0266] Treating cancer can also result in a decrease in the mortality rate of a population of treated subjects in comparison to an untreated population. For example, the mortality rate is decreased by more than 2% (e.g., more than 5%, 10%, or 25%). A decrease in the mortality rate of a population of treated subjects may be measured by any reproducible means, for example, by calculating for a population the average number of disease-related deaths per unit time following initiation of treatment with a pharmaceutically acceptable salt of the invention. A decrease in the mortality rate of a population may also be measured, for example, by calculating for a population the average number of disease-related deaths per unit time following completion of a first round of treatment with a pharmaceutically acceptable salt of the invention.

[0267] Exemplary cancers that may be treated by the invention include, but are not limited to, non-small cell lung cancer, small-cell lung cancer, colorectal cancer, bladder cancer, glioma, breast cancer, melanoma, non-melanoma skin cancer, endometrial cancer, esophagogastric cancer, pancreatic cancer, hepatobiliary cancer, soft tissue sarcoma, ovarian cancer, head and neck cancer, renal cell carcinoma, bone cancer, non-Hodgkin lymphoma, prostate cancer, embryonal tumor, germ cell tumor, cervical cancer, thyroid cancer, salivary gland cancer, gastrointestinal neuroendocrine tumor, uterine sarcoma, gastrointestinal stromal tumor, CNS cancer, thymic tumor, Adrenocortical carcinoma, appendiceal cancer, small bowel cancer and penile cancer.

Combination Formulations and Uses Thereof

[0268] The compounds of the invention can be combined with one or more therapeutic agents. In particular, the therapeutic agent can be one that treats or prophylactically treats any cancer described herein.

Combination Therapies

[0269] A compound of the invention can be used alone or in combination with an additional therapeutic agent, e.g., other agents that treat cancer or symptoms associated therewith, or in combination with other types of treatment to treat cancer.

Pharmaceutical Compositions

[0275] The compounds of the invention are preferably formulated into pharmaceutical compositions for administration to a mammal, preferably, a human, in a biologically compatible form suitable for administration in vivo. Accordingly, in an aspect, the present invention provides a pharmaceutical composition comprising a compound of the invention in admixture with a suitable diluent, carrier, or excipient.

[0276] The compounds of the invention may be used in the form of the free base, in the form of salts, solvates, and as prodrugs. All forms are within the scope of the invention. In accordance with the methods of the invention, the described compounds or salts, solvates, or prodrugs thereof may be administered to a patient in a variety of forms depending on the selected route of administration, as will be understood by those skilled in the art. The compounds of the invention may be administered, for example, by oral, parenteral, buccal, sublingual, nasal, rectal, patch, pump, or transdermal administration and the pharmaceutical compositions formulated accordingly. Parenteral administration includes intravenous, intraperitoneal, subcutaneous, intramuscular, transepithelial, nasal, intrapulmonary, intrathecal, rectal, and topical modes of administration. Parenteral administration may be by continuous infusion over a selected period of time.

[0277] A compound of the invention may be orally administered, for example, with an inert diluent or with an assimilable edible carrier, or it may be enclosed in hard- or soft-shell gelatin capsules, or it may be compressed into tablets, or it may be incorporated directly with the food of the diet. For oral therapeutic administration, a compound of the invention may be incorporated with an excipient and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, and wafers. A compound of the invention may also be administered parenterally. Solutions of a compound of the invention can be prepared in water suitably mixed with a surfactant. Under ordinary conditions of storage and use, these preparations may contain a preservative to prevent the growth of microorganisms. Conventional procedures and ingredients for the selection and preparation of suitable formulations are described, for example, in Remington's Pharmaceutical Sciences (2003, 20th ed.) and in The United States Pharmacopeia: The National Formulary (USP 24 NF19), published in 1999. The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases the form must be sterile and must be fluid to the extent that may be easily administered via syringe. Compositions for nasal administration may conveniently be formulated as aerosols, drops, gels, and powders. Aerosol formulations typically include a solution or fine suspension of the active substance in a physiologically acceptable aqueous or non-aqueous solvent and are usually presented in single or multidose quantities in sterile form in a sealed container, which can take the form of a cartridge or refill for use with an atomizing device. Alternatively, the sealed container may be a unitary dispensing device, such as a single dose nasal inhaler or an aerosol dispenser fitted with a metering valve which is intended for disposal after use. Where the dosage form comprises an aerosol dispenser, it will contain a propellant, which can be a compressed gas, such as compressed air or an organic propellant. The aerosol dosage forms can also take the form of a pump-atomizer. Compositions suitable for buccal or sublingual administration include tablets, lozenges, and pastilles, where the active ingredient is formulated with a carrier. Compositions for rectal administration are conveniently in the form of suppositories containing a conventional suppository base. A compound described herein may be administered intratumorally, for example, as an intratumoral injection. Intratumoral injection is injection directly into the tumor vasculature and is specifically contemplated for discrete, solid, accessible tumors. Local, regional, or systemic administration also may be appropriate. A compound described herein may advantageously be contacted by administering an injection or multiple injections to the tumor, spaced for example, at approximately, 1 cm intervals. In the case of surgical intervention, the present invention may be used preoperatively, such as to render an inoperable tumor subject to resection. Continuous administration also may be applied where appropriate, for example, by implanting a catheter into a tumor or into tumor vasculature.

[0278] The compounds of the invention may be administered to an animal, e.g., a human, alone or in combination with pharmaceutically acceptable carriers, as noted herein, the proportion of which is determined by the solubility and chemical nature of the compound, chosen route of administration, and standard pharmaceutical practice.

Dosages

[0279] The dosage of the compounds of the invention, and/or compositions comprising a compound of the invention, can vary depending on many factors, such as the pharmacodynamic properties of the compound; the mode of administration; the age, health, and weight of the recipient; the nature and extent of the symptoms; the frequency of the treatment, and the type of concurrent treatment, if any; and the clearance rate of the compound in the animal to be treated. One of skill in the art can determine the appropriate dosage based on the above factors. The compounds of the invention may be administered initially in a suitable dosage that may be adjusted as required, depending on the clinical response. In general, satisfactory results may be obtained when the compounds of the invention are administered to a human at a daily dosage of, for example, between 0.05 mg and 3000 mg. Dose ranges include, for example, between 10-1000 mg.

[0280] Alternatively, the dosage amount can be calculated using the body weight of the patient. For example, the dose of a compound, or pharmaceutical composition thereof, administered to a patient may range from 0.1-100 mg/kg.

Example 2. Assay for ATPase Catalytic Activity of BRM and BRG-1

[0719] The ATPase catalytic activity of BRM or BRG-1 was measured by an in vitro biochemical assay using ADP-Glo™ (Promega, V9102). The ADP-Glo™ kinase assay is performed in two steps once the reaction is complete. The first step is to deplete any unconsumed ATP in the reaction. The second step is to convert the reaction product ADP to ATP, which will be utilized by the luciferase to generate luminesce and be detected by a luminescence reader, such as Envision.

[0720] The assay reaction mixture (10 μL) contains 30 nM of BRM or BRG-1, 20 nM salmon sperm DNA (from Invitrogen, UltraPure™ Salmon Sperm DNA Solution, cat #15632011), and 400 μM of ATP in the ATPase assay buffer, which comprises of 20 mM Tris, pH 8, 20 mM MgCl.sub.2, 50 mM NaCl, 0.1% Tween-20, and 1 mM fresh DTT (Pierce™ DTT (Dithiothreitol), cat #20290). The reaction is initiated by the addition of the 2.5 μL ATPase solution to 2.5 μL ATP/DNA solution on low volume white Proxiplate-384 plus plate (PerkinElmer, cat #6008280) and incubates at room temperature for 1 hour. Then, following addition of 5 μL of ADP-Glo™ Reagent provided in the kit, the reaction incubates at room temperature for 40 minutes. Then, 10 μL of Kinase Detection Reagent provided in the kit is added to convert ADP to ATP, and the reaction incubates at room temperature for 60 minutes. Finally, luminescence measurement is collected with a plate-reading luminometer, such as Envision.

[0721] BRM and BRG-1 were synthesized from high five insect cell lines with a purity of greater than 90%. IC.sub.50 data from the ATPase catalytic activity assay described herein are shown in Table 10 below.

Example 3. Assay for Inhibitory Effects on BRG1 and BRM-Dependent Transcription

[0722] The potential inhibitory effects of compounds on BRG1 and BRM dependent transcription was study by testing the activity of against the BRG1 mutant lung cancer cell line A549 and a MDA cell line with BRM removed by CRISPR. Both cell lines were genetically engineered with a BRG1 or BRM-dependent mouse mammary tumor virus luciferase reporter.

Example 4. Synthesis of Compound A

[0724] BRG1/BRM Inhibitor compound A has the structure:

##STR00742##

[0725] Compound A was synthesized as shown in Scheme 1 below.

##STR00743##

[0726] The ATPase catalytic activity of BRM or BRG-1 in the presence of Compound A was measured by the in vitro biochemical assay using ADP-Glo™ (Promega, V9102) described above. Compound A was found to have an IC.sub.50 of 10.4 nM against BRM and 19.3 nM against BRG1 in the assay.

Example 5. Effects of BRG1/BRM ATPase Inhibition on the Growth of Uveal Melanoma and Hematological Cancer Cell Lines

[0727] Procedure: Uveal melanoma cell lines (92-1, MP41, MP38, MP46), prostate cancer cell lines (LNCAP), lung cancer cell lines (NCI-H1299), and immortalized embryonic kidney lines (HEK293T) were plated into 96 well plates with growth media (see Table 9). BRG1/BRM ATPase inhibitor, Compound A, was dissolved in DMSO and added to the cells in a concentration gradient from 0 to 10 micromolar at the time of plating. Cells were incubated at 37 degrees Celsius for 3 days. After three days of treatment, the media was removed from the cells and 30 microliters of TrypLE (Gibco) was added to cells for 10 minutes. Cells were detached from the plates and resuspended with the addition of 170 microliters of growth media. Cells from two DMSO-treated control wells were counted, and the initial number of cells plated at the start of the experiment, were re-plated into fresh-compound containing plates for an additional four days at 37 degrees Celsius. At day 7, cells were harvested as described above. On day 3 and day 7, relative cell growth was measured by the addition of Cell-titer glo (Promega) and luminescence was measured on an Envision plate reader (Perkin Elmer). The concentration of compound at which each cell line's growth was inhibited by 50% (GI.sub.50), was calculated using Graphpad Prism, and is plotted below. For multiple myeloma cell lines (OPM2, MM1S, LP1), ALL cell lines (TALL1, JURKAT, RS411), DLBCL cell lines (SUDHL6, SUDHL4, DB, WSUDLCL2, PFEIFFER), AML cell lines (OCIAML5), MDS cell lines (SKM1), ovarian cancer cell lines (OV7, TYKNU), esophageal cancer cell lines (KYSE150), rhabdoid tumor lines (RD, G402, G401, HS729, A204), liver cancer cell lines (HLF, HLE, PLCRPF5), and lung cancer cell lines (SW1573, NCIH2444), the above methods were performed with the following modifications: Cells were plated in 96 well plates, and the next day, BRG1/BRM ATPase inhibitor, Compound A, was dissolved in DMSO and added to the cells in a concentration gradient from 0 to 10 micromolar. At the time of cell splitting on days 3 and 7, cells were split into new 96 well plates, and fresh compound was added four hours after re-plating.

[0729] Results: As shown in FIG. 1, the uveal melanoma and hematologic cancer cell lines were more sensitive to BRG1/BRM inhibition than the other tested cell lines. Inhibition of the uveal melanoma and hematologic cancer cell lines was maintained through day 7.

Example 6. Comparison of BRG1/BRM Inhibitors to Clinical PKC and MEK Inhibitors in Uveal Melanoma Cell Lines

[0730] Procedure: Uveal melanoma cell lines, 92-1 or MP41, were plated in 96 well plates in the presence of growth media (see Table 12). BAF ATPase inhibitors (Compound A), PKC inhibitor (LXS196; MedChemExpress), or MEK inhibitor (Selumetinib; Selleck Chemicals) were dissolved in DMSO and added to the cells in a concentration gradient from 0 to 10 micromolar at the time of plating. Cells were incubated at 37 degrees Celsius for 3 days. After three days of treatment, cell growth was measured with Cell-titer glow (Promega), and luminescence was read on an Envision plate reader (Perkin Elmer).

[0731] Results: As shown in FIG. 2A and FIG. 2B, Compound A showed comparable growth inhibition of uveal melanoma cells as the clinical PKC and MEK inhibitors. Further, compound A was found to result in a faster onset of inhibition than the clinical PKC and MEK inhibitors.

[0738] Results: As shown in FIG. 3, the uveal melanoma, hematologic cancer, prostate cancer, breast cancer, and Ewing's sarcoma cell lines were more sensitive to BRG1/BRM inhibition than the other tested cell lines. Inhibition of the uveal melanoma, hematologic cancer, prostate cancer, breast cancer, and Ewing's sarcoma cell lines was maintained through day 7.

Example 9. Effects of BRG1/BRM ATPase Inhibition on the Growth of Cancer Cell Lines

[0739] Procedure: A pooled cell viability assay was performed using PRISM (Profiling Relative Inhibition Simultaneously in Mixtures) as previously described (“High-throughput identification of genotype-specific cancer vulnerabilities in mixtures of barcoded tumor cell lines”, Yu et al, Nature Biotechnology 34, 419-423, 2016), with the following modifications. Cell lines were obtained from the Cancer Cell Line Encyclopedia (CCLE) collection and adapted to RPMI-1640 medium without phenol red, supplemented with 10% heat-inactivated fetal bovine serum (FBS), in order to apply a unique infection and pooling protocol to such a big compendium of cell lines. A lentiviral spin-infection protocol was executed to introduce a 24 nucleotide-barcode in each cell line, with an estimated multiplicity of infection (MOI) of 1 for all cell lines, using blasticidin as selection marker. Over 750 PRISM cancer cell lines stably barcoded were then pooled together according to doubling time in pools of 25. For the screen execution, instead of plating a pool of 25 cell lines in each well as previously described (Yu et al.), all the adherent or all the suspension cell line pools were plated together using T25 flasks (100,000 cells/flask) or 6-well plates (50,000 cells/well), respectively. Cells were treated with either DMSO or compound in a 8-point 3-fold dose response in triplicate, starting from a top concentration of 10 μM. As control for assay robustness, cells were treated in parallel with two previously validated compounds, the pan-Raf inhibitor AZ-628, and the proteasome inhibitor bortezomib, using a top concentration of 2.5 μM and 0.039 μM, respectively.

[0740] Following 3 days of treatment with compounds, cells were lysed, genomic DNA was extracted, barcodes were amplified by PCR and detected with Next-Generation Sequencing. Cell viability was determined by comparing the counts of cell-line specific barcodes in treated samples to those in the DMSO-control and Day 0 control. Dose-response curves were fit for each cell line and corresponding area under the curves (AUCs) were calculated and compared to the median AUC of all cell lines (FIG. 4). Cell lines with AUCs less than the median were considered most sensitive.

Example 10. Effects of BRG1/BRM ATPase Inhibitors on the Growth of Uveal Melanoma Cell Lines

BRG1/BRM ATPase inhibitor, compound 67, was dissolved in DMSO and added to the cells in a concentration gradient from 0 to 10 micromolar at the time of plating. Cells were incubated at 37° C. for 3 days. After three days of treatment, cell growth was measured with Cell-titer glow (Promega), and luminescence was read on an Envision plate reader (Perkin Elmer).

[0742] Results: As shown in FIG. 5, Compound B resulted in potent growth inhibition in the uveal melanoma cell lines.

Example 11. Comparison of BRG1/BRM Inhibitors to Clinical PKC and MEK Inhibitors in Uveal Melanoma Cell Lines

[0743] Procedure: Uveal melanoma cell lines, 92-1 or MP41, were plated in 96 well plates in the presence of growth media (see Table 9). BAF ATPase inhibitor (Compound B), PKC inhibitor (LXS196; MedChemExpress), and MEK inhibitor (Selumetinib; Selleck Chemicals) were dissolved in DMSO and added to the cells in a concentration gradient from 0 to 10 micromolar at the time of plating. Cells were incubated at 37° C. for 3 days. After three days of treatment, cell growth was measured with Cell-titer glow (Promega), and luminescence was read on an Envision plate reader (Perkin Elmer).

[0744] Results: As shown in FIG. 6A and FIG. 6B, Compound B showed more potent effects on growth inhibition of uveal melanoma cells as compared to the clinical PKC and MEK inhibitors. Further, Compound B was found to result in a faster onset of growth inhibition than the clinical PKC and MEK inhibitors.

Example 12. BRG1/BRM ATPase Inhibitors are Effective at Inhibiting the Growth of PKC Inhibitor-Resistant Cells

[0745] Procedure: MP41 uveal melanoma cells were made resistant to the PKC inhibitor (LXS196; MedChemExpress), by long-term culture in growth media (see Table 9) containing increasing concentrations of the compound, up to 1 micromolar. After 3 months, sensitivity of the parental MP41 cells and the PKC inhibitor (PKCi)-resistant cells to the PKC inhibitor (LXS196) or the BRG1/BRM ATPase inhibitor (Compound B) was tested in a 7-day growth inhibition assay as described above in Example 6.

[0746] Results: While the PKCi-resistant cells could tolerate growth at higher concentrations of LXS196 than could the parental MP41 cell line (FIG. 7A), the BRG1/BRM ATPase inhibitor (Compound B) still resulted in strong growth inhibition of both the PKCi-resistant and parental cell lines (FIG. 7B). The PKCi-resistant cells were more sensitive to Compound B than were the parental MP41 cells (FIG. 7B).

Example 14. BRG1/BRM ATPase Inhibitors Cause Uveal Melanoma Tumor Growth Inhibition In Vivo

[0764] Procedure: Nude mice (Envigo) were engrafted subcutaneously in the axillary region with 5×10.sup.6 92-1 uveal melanoma cells in 50% Matrigel. Tumors were grown to a mean of ˜200 mm.sup.3, at which point mice were grouped and dosing was initiated. Mice were dosed once daily by oral gavage with vehicle (20% 2-Hydroxypropyl-β-Cyclodextrin) or increasing doses of Compound C. Tumor volumes and body weights were measured over the course of 3 weeks, and doses were adjusted by body weight to achieve the proper dose in terms of mg/kg. At this time, animals were sacrificed, and tumors were dissected and imaged.

[0765] Results: Treatment with Compound C led to tumor growth inhibition in a dose-dependent manner with tumor regression observed at the highest (50 mg/kg) dose. (FIG. 8A and FIG. 8B). All treatments were well tolerated with no body weight loss observed (FIG. 8C).
