Description

INDAZOLE—S-CARBOXAMIDES AND THEIR USE AS WNT/B-CATENIN SIGNALING PATHWAY INHIBITORS RELATED APPLICATIONS Cross—Reference to Related Applications This application claims the benefit of U.S. Provisional Application No. 61/534,601, filed September 14, 2011, and U.S. Provisional Application No. 61/624,646, filed April 16, 2012, which are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION Field of the Invention This invention relates to the field of therapeutic oncology. More particularly, it concerns the use of an indazole-3—carboxamide compound or salts or s thereof, in the treatment of cancer, particularly colon, ovarian, atic, breast, liver, te and hematologic s.
Description of the Related Art Pattern formation is the activity by which embryonic cells form ordered spatial arrangements of entiated tissues. Speculation on the mechanisms underlying these patterning s usually centers on the secretion of a signaling molecule that elicits an appropriate response from the tissues being patterned. More recent work aimed at the identification of such signaling molecules implicates secreted proteins encoded by individual members of a small number of gene families.
A anding idea in cancer biology is that cancers arise and grow due to the formation of cancer stem cells, which may constitute only a minority of the cells within a tumor but are nevertheless critical for its propagation. Stem cells are appealing as the cell of origin for cancer because of their pre—existing capacity for self— renewal and for unlimited" ation. In addition, stem cells are relatively long-lived in comparison to other cells within s, providing a greater opportunity to accumulate the multiple additional ons that may be required to increase the rate of cell eration and produce clinically significant cancers. Of particular recent interest in the origin of cancer is the observation that the Wnt signaling pathway, which has been ated in stem cell self-renewal in normal s, upon continuous activation has also been associated with the initiation and growth of many types of cancer. This pathway thus provides a potential link n the normal self—renewal of stem cells and the aberrantly regulated proliferation of cancer stem cells.
The Wnt growth factor family includes more than 10 genes fied in the mouse and at least 19 genes identified in the human. Members of the Wnt family of signaling molecules mediate many important short-and long-range patterning processes during invertebrate and vertebrate development. The Wnt signaling pathway is known for its important role in the ive interactions that regulate growth and differentiation, and plays important roles in the homeostatic maintenance of post—embryonic tissue integrity. Wnt stabilizes cytoplasmic B-catenin, which stimulates the sion of genes including c-myc, c jun, fra—l, and cyclin D1. In addition, misregulation of Wnt signaling can cause developmental'defects and is implicated in the genesis of several human s. More recently, the Wnt pathway has been implicated in the maintenance of stem or progenitor cells in a growing list of adult tissues that now includes skin, blood, gut, prostate, muscle and the nervous system.
Pathological activation of the Wnt pathway is also believed to be the initial event leading to colorectal cancer in over 85% of all sporadic cases in the Western world. Activation of the Wnt pathway has also been extensively reported for hepatocellular oma, breast cancer, ovarian cancer, pancreatic cancer, mas, mesotheliomas, lymphomas and leukemias. In addition to cancer, inhibitors of the Wnt pathway can be used for stem cell ch or for the treatment of any diseases characterized by aberrant Wnt activation such as diabetic retinopathy, pulmonary fibrosis, rheumatoid arthritis, scleroderma as well as mycotic and viral infections and bone and cartilage diseases. As such, it is a eutic target that is of great interest to the field.
In addition to cancer, there are many cases of genetic diseases due to mutations in Wnt signaling components. Examples of some of the many diseases are Alzheimer's disease [Proc Natl. Acad. Sci. U S A (2007), 104(22), 9434-9], osteoarthritis, polyposis coli ce (1991), 253(5020), 665—669], bone density and vascular defects in the eye porosis-pseudoglioma syndrome, OPPG) [N. Engl. J Med.

Wnt pathway modulates in neural tissue, among other things, axon pathfinding, dendritic development, and synaptic assembly. Through different receptors, Wnt pathway activates and/or regulates diverse signaling pathways and other processes that lead to local changes on the cytoskeleton or global cellular changes involving nuclear function. Recently, a link n neuronal activity, essential for the formation and refinement of neuronal connections, and Wnt signaling has been red. Indeed, neuronal activity regulates the e of various Wnt proteins and the zation of their receptors. Wnt pathway mediates synaptic structural s induced WO 40215 2012/055172 by neuronal activity or experience. Evidence suggests that dysfunction in Wnt signaling contributes to neurological disorders [Brain Research Reviews (2000), 33(1), 1—12; Oncogene (2006) 25(57), 7545-7553; Molecular Neurodegeneration (2008), 3, 9; Neurobiology of Disease (2010), 38(2), 148—153; Journal of Neuroa’evelopmental Disorders , 3(2), 162—174 and Cold Spring Harbor Perspectives in Biology February (2012), 4(2)].

"Therapeutically effective amount" is also intended to include one or more of the nds of formula (I) in combination with one or more other agents that are effective to inhibit Wnt related diseases and/or conditions. The combination of compounds is preferably a synergistic combination. Synergy, as described, for example, by Chou and y, Advances in Enzyme Regulation (1984), 22, 27-55, occurs when the effect of the nds when administered in combination is greater than the additive effect of the compounds when stered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. It will be appreciated that different concentrations may be employed for prophylaxis than for ent of an active disease. This amount can further depend upon the t’s , weight, sex, age and medical history.
A therapeutic effect relieves, to some extent, one or more of the symptoms of the disease, and includes curing a disease. g" means that the symptoms of active disease are eliminated. However, certain long—term or permanent effects of the disease may exist even after a cure is obtained (such as extensive tissue damage).
"Treat," "treatment," or "treating," as used herein refers to administering a pharmaceutical composition for therapeutic purposes. The term "therapeutic treatment" refers to administering treatment to a patient y suffering from a disease thus causing a therapeutically beneficial effect, such as ameliorating existing symptoms, preventing additional symptoms, ameliorating or preventing the underlying metabolic causes of ms, postponing or preventing the further development of a disorder and/or reducing the severity of symptoms that will or are expected to develop.
Compounds The compounds and compositions described herein can be used as anti—proliferative agents, e.g., anti-cancer and anti-angiogenesis agents, and as inhibitors of the Wnt signaling pathway, e.g., for ng diseases or disorders ated with aberrant Wnt signaling. In addition, the compounds can be used as inhibitors of one or more kinases, kinase receptors, or kinase complexes. Such compounds and itions are also useful for controlling cellular proliferation, differentiation, and/or apoptosis.

It is to be noted that concentrations and dosage values may also vary with the severity of the ion to be alleviated. It is to be further understood that for any particular patient, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supelvising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or ce of the claimed compositions.
Solid compositions can be provided in various different types of dosage forms, depending on the physicochemical properties of the drug, the desired dissolution rate, cost considerations, and other criteria. In one of the embodiments, the solid composition is a single unit. This implies that one unit dose of the drug is comprised in a , physically shaped solid form or article. In other words, the solid composition is coherent, which is in contrast to a le unit dosage form, in which the units are rent.
Examples of single units which may be used as dosage forms for the solid composition include tablets, such as compressed s, film—like units, foil—like units, wafers, lyophilized matrix units, and the like. In a preferred embodiment, the solid WO 40215 composition is a highly porous lyophilized form. Such lyophilizates, sometimes also called wafers or lyophilized tablets, are particularly useful for their rapid disintegration, which also enables the rapid dissolution of the active compound.
On the other hand, for some applications the solid composition may also be formed as a le unit dosage fonn as defined above. es of multiple units are powders, granules, microparticles, pellets, mini-tablets, beads, lyophilized powders, and the like. In one embodiment, the solid composition is a lyophilized powder.
Such a dispersed lyophilized system comprises a multitude of powder particles, and due to the lyophilization process used in the ion of the , each particle has an irregular, porous microstructure through which the powder is capable of absorbing water very rapidly, resulting in quick dissolution. Effervescent compositions are also contemplated to aid the quick sion and absorption of the compound.
] Another type of articulate system which is also capable of achieving rapid drug dissolution is that of powders, granules, or pellets from water- soluble excipients which are coated with the drug, so that the drug is located at the outer surface of the individual particles. In this type of system, the water-soluble low molecular weight excipient is useful for preparing the cores of such coated particles, which can be subsequently coated with a coating composition comprising the drug and, preferably, one or more additional excipients, such as a binder, a pore former, a saccharide, a sugar alcohol, a film-forming polymer, a cizer, or other excipients used in pharmaceutical coating compositions.

Evaluation of Biological Activity The biological activity of the compounds described herein can be tested using any suitable assay known to those of skill in the art, e. g., or . For e, the activity of a compound may be tested using one or more of the test methods outlined below.
In one example, tumor cells may be screened for Wnt independent growth. In such a method, tumor cells of interest are contacted with a nd (i.e. inhibitor) of interest, and the proliferation of the cells, e.g. by uptake of tritiated thymidine, is monitored. In some embodiments, tumor cells may be isolated from a candidate patient who has been screened for the ce of a cancer that is associated with a on in the Wnt signaling pathway. Candidate cancers include, without limitation, those listed above.
In another example, one may utilize in vitro assays for Wnt ical activity, e.g. stabilization of nin and promoting growth of stem cells. Assays for ical activity of Wnt include stabilization of fi-catenin, which can be measured, for example, by serial dilutions of a candidate inhibitor composition. An exemplary assay for Wnt ical activity contacts a Wnt composition in the presence of a candidate inhibitor with cells, e.g. mouse L cells. The cells are cultured for a period of time sufficient to stabilize B-catenin, usually at least about 1 hour, and lysed. The cell lysate is resolved by SDS PAGE, then transferred to nitrocellulose and probed with dies specific for B-catenin.
In a r example, the activity of a candidate compound can be measured in a Xenopus secondary axis bioassay (Leyns, L. et al. Cell (1997), 88(6), 747- 756).
Example 7 Another screening assay for Wnt activity is described as follows.
Reporter cell lines can be generated by stably ucing cells of cancer cell lines (e.g., colon cancer) with a lentiviral construct that include a wnt-responsive promoter g expression of the firefly luciferase gene.
Lentiviral ucts can be made in which the SP5 promoter, a promoter having eight TCF/LEF binding sites derived from the SP5 er, is linked upstream of the firefly luciferase gene. The lentiviral constructs can also include a hygromycin resistance gene as a selectable . The SP5 promoter construct can be used to transduce SW480 cells, a colon cancer cell line having a mutated APC gene that generates a truncated APC protein, leading to de-regulated accumulation of nin. A control cell line can be generated using another lentiviral construct containing the luciferase gene under the control of the SV40 promoter which does not e B-catenin for activation.
Cultured SW480 cells bearing a er construct can be distributed at approximately 10,000 cells per well into 96 well or 384 well plates. Compounds from a small molecule compound library can then be added to the wells in half-log dilutions using a ten olar top concentration. A series of control wells for each cell type receive only buffer and compound solvent. Twenty-four to forty hours after the addition of compound, reporter activity for luciferase can be assayed, for example, by addition of the Glo luminescence reagent (Promega) and the Victor3 plate reader (Perkin Elmer). gs can be normalized to DMSO only treated cells, and ized activities can then be used in the IC50 calculations. Table 2 shows the activity of selected indazole-3 -carboxamide analogs.
