DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS OF THE INVENTION
[0115] The current invention derives from the discovery that the benzoisochromane quinones (BIQs), such as the granaticins, inhibit protein kinase activity. The granaticins, in particular, were found to inhibit Cdc kinase activity based upon hits identified from high-thoroughput screening (HTS) of over 300,000 compounds for their ability to inhibit a heterodimer of a kinase (Cdc7) and an activator (Dbf4) that phosphorylates serine and threonine residues.
[0116] The present invention provides methods for the inhibition of protein kinase activity, such as Cdc kinase activity, and particularly, Cdc7 kinase activity. The inhibitory compounds useful in the methods include, but are not limited to, granaticin A, granaticin B, dihydrogranaticin A, dihydrogranaticin B, medermycin, actinorhodin, benzoisochromanequinones, as shown herein. The methods of the present invention are useful in the treatment of kinase-related diseases or disorders. Specifically, the methods are useful in the treatment of proliferative disorders, such as cancer, benign tumors, inflammatory disorders, and complications thereof. The present invention also provides pharmaceutical compositions and kits for the treatment of various diseases.

Protein Kinases, Cdc7, and Dbf4
[0197] Compounds useful in the present invention are protein kinase inhibitors. The protein kinases constitute a group of enzymes that catalyse the phosphorylation of hydroxy groups of specific protein residues such as tyrosine, serine or threonine residues. Said phosphorylations can extensively modify the function of proteins; thus, the protein kinases play an important role in the regulation of a great variety of cellular processes, notably including metabolism, cellular proliferation, cell differentiation or cell survival. Among the various cellular functions in which the activity of a protein kinase is involved, certain processes represent attractive targets for treating certain diseases. As an example, we may notably mention angiogenesis and control of the cell cycle, in which the protein kinases can play an essential role. These processes are essential for the growth of solid tumours as well as for the development of other diseases.
[0198] The protein kinases participate in signalling events that control the activation, growth and differentiation of cells in response either to extracellular mediators, or to changes in the environment. In general, these kinases belong to two groups: those which phosphorylate serine and/or threonine residues preferentially, and those which phosphorylate tyrosine residues preferentially (S. K. Hanks and T. Hunter, FASEB. J., 1995, 9, pages 576-596). The serine/threonine kinases, for example, are isoforms of protein kinases C (A. C. Newton, J. Biol. Chem., 1995, 270, pages 28495-28498) and a group of cyclin-dependent kinases, such as Cdc2 (Cdk1) (J. Pines, Trends in Biochemical Sciences, 1995, 18, pages 195-197). The tyrosine kinases include growth factor receptors, such as the epidermal growth factor (EGF) receptor (S. Iwashita and M. Kobayashi, Cellular Signalling, 1992, 4, pages 123-132), and cytosolic kinases such as p56tck, p59fYn, ZAP-70 and the csk kinases (C. Chan et al., Ann. Rev. Immunol., 1994, 12, pages 555-592).
[0199] Abnormally high levels of protein kinase activity have been associated with many diseases, resulting in abnormal cellular functions. This can occur either directly or indirectly, from a malfunction in the control mechanisms of kinase activity, connected for example with a mutation, overexpression or inappropriate activation of the enzyme, or with overproduction or underproduction of cytokines or of growth factors, which are also involved in signal transduction upstream or downstream of the kinases. In all these cases, selective inhibition of the action of the kinases offers hope of a beneficial effect. Among these protein kinases, we may mention quite particularly protein kinase Cdc7. Cdc7 is a serine/threonine kinase that has been characterized at the molecular level as a factor that is essential for initiating DNA replication.
[0200] The catalytic activity of Cdc7, which is conserved throughout the eukaryotes, is dependent on its Dbf4 regulatory subunit. Although the expression of Cdc7 (at the level of messenger and protein RNA) is constant throughout the cell cycle, the level of expression of Dbf4 is in contrast dependent on the cell cycle, which induces an increase in Cdc7 kinase activity during the G1-S transition. For this reason, Cdc7 is given the designation DDK (Dbf-4-dependent kinase).
[0201] The principal activity of the Cdc7/Dbf4 complex occurs on initiation of DNA replication during the S phase. It phosphorylates MCM2 which thus activates the MCM (MiniChromosome Maintenance) complex, which is an essential component of DNA-helicase activity.
[0202] Cdc7 also plays an important role in mutagenesis, mainly induced by action at the level of the DNA-damage pathways and checkpoints, in particular at the ATR-dependent checkpoint, which prevents the initiation of DNA replication in response to damage of the single-stranded type caused by chemical agents such as etoposide.
[0203] Cdc7 and Dbf4 are overexpressed in human tumour cell lines and in many tumour samples (lung, breast, thyroid, colon-rectum, oesophagus, uterus, testicle, liver) in comparison with the corresponding normal tissues (Hess, G. F., Drong, R. F., et al. 1998).
[0204] Experiments in suppressing Cdc7 expression using RNA interference (RNAi) technology show that inhibition of Cdc7 expression induces arrest of the cell cycle and prevents cellular proliferation of the human tumour cell lines HeLa and HCT116, but has a limited effect on normal cells (normal human skin fibroblasts). This is reflected in a prolonged stoppage in G1 that induces apoptosis in cells lacking p53 (>50% of tumours) but is reversible in normal cells [A. Montagnoli et al., CANCER RESEARCH 64, 7110-7116, Oct. 1, 2004].
[0205] The inhibitors of Cdc7 kinase activity can constitute a novel category of targeted cytotoxic therapy as well as of inhibitors of DNA replication. Such inhibitors would inhibit replication before the replication forks are established, thus blocking replication without damaging the DNA. The present application thus relates in particular to novel inhibitors of protein kinase Cdc7 that can be used notably for the treatment of abnormal cellular proliferation and more particularly in oncology.

[0275] Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
[0276] The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
[0277] In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.
[0278] Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the conjugates of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.
[0279] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may comprise buffering agents.
[0280] Solid compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally comprise opacifying agents and can be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. Solid compositions of a similar type can be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.
[0281] The active ingredients can be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art.

Kits
[0303] In still another aspect, the present invention also provides kits (e.g., pharmaceutical packs) for treating a proliferative disorder comprising a compound of the Formula (A) or (B) and instructions for administration to a subject for treating a proliferative disorder. Kits may comprise a provided composition and a container (e.g., a vial, ampoule, bottle, syringe, and/or dispenser package, or other suitable container). In some embodiments, provided kits may optionally further include a second container comprising a suitable aqueous carrier for dilution or suspension of the provided composition for preparation of administration to a subject. In some embodiments, contents of provided formulation container and solvent container combine to form at least one unit dosage form.
[0304] Optionally, a single container may comprise one or more compartments for containing a provided composition, and/or appropriate aqueous carrier for suspension or dilution. In some embodiments, a single container can be appropriate for modification such that the container may receive a physical modification so as to allow combination of compartments and/or components of individual compartments. For example, a foil or plastic bag may comprise two or more compartments separated by a perforated seal which can be broken so as to allow combination of contents of two individual compartments once the signal to break the seal is generated. A pharmaceutical pack or kit may thus comprise such multi-compartment containers including a provided composition and appropriate solvent and/or appropriate aqueous carrier for suspension.
[0305] Optionally, instructions for use are additionally provided in such kits of the invention. Such instructions may provide, generally, for example, instructions for dosage and administration. In other embodiments, instructions may further provide additional detail relating to specialized instructions for particular containers and/or systems for administration. Still further, instructions may provide specialized instructions for use in conjunction and/or in combination with additional therapy.
EXAMPLES
[0306] In order that the invention described herein may be more fully understood, the following examples are set forth. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting this invention in any manner.
Example 1. Inhibition of Primary Patient Samples
[0307] Table 1 highlights a series of primary patient leukemia samples-both acute and chronic and treatment naïve and refractory and the effect of granaticin A, granaticin B, derivative 1, and derivative 2 to inhibit cellular proliferation. The IC50 data reveals that granaticin B is approximately one log more active than granaticin A against all the samples tested and inhibits cellular proliferation in the low nanomolar range. The two starred samples represent serial samples taken from the same patients after they received 2-3 cycles of additional high dose salvage chemotherapy and indicate that although refractory to salvage chemotherapy, the Cdc7 pathway remains a potentially efficacious target as the sensitivity to these compounds remains unchanged. Importantly, each patient sample was resistant to the prior therapy received using this assay.
