1 -(5-TERT-BUTYL-2-ARYL-PYRAZOL-3-YL)-3-[2-FLUORO-4-[(3-OXO-4H-PYRIDO[2, 3-B]PYRAZIN-8-YL)OXY]PHENYL]UREA DERIVATIVES AS RAF INHIBITORS FOR THE TREATMENT OF CANCER

The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain 1-(5-tert-butyl-2-aryl-pyrazol-3-yl)- 3-[2-fluoro-4-[(3-oxo-4H-pyrido[2,3-b]pyrazin-8-yl)oxy]phenyl]urea compounds (referred herein as "TBAP compounds") that, inter alia, inhibit RAF (e.g., BRAF, CRAF, etc.). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit RAF (e.g., BRAF, CRAF, etc.); and to treat disorders including: proliferative disorders; cancer (including, e.g., malignant melanoma, colorectal carcinoma, pancreatic adenocarcinoma); inflammation; immunological disorders; viral infections; fibrotic disorders; disorders associated with a mutated form of RAF (e.g., BRAF, CRAF, etc.); disorders ameliorated by the inhibition of RAF (e.g., BRAF, CRAF, etc.); disorders ameliorated by the inhibition of mutant BRAF; disorders ameliorated by the inhibition of BRAF and CRAF; disorders associated with RAS mutations and/or MAPK pathway activation; disorders ameliorated by the inhibition of SRC, p38, FGFRA, VEGFR-2 (KDR), and/or LCK; etc.

Novel hinge binder improves activity and pharmacokinetic properties of BRAF inhibitors

Mutated BRAF serine/threonine kinase is implicated in several types of cancer, with particularly high frequency in melanoma and colorectal carcinoma. We recently reported on the development of BRAF inhibitors based on a tripartite A?B?C system featuring an imidazo[4,5]pyridin-2-one group hinge binder. Here we present the design, synthesis, and optimization of a new series of inhibitors with a different A?B?C system that has been modified by the introduction of a range of novel hinge binders (A ring). The optimization of the hinge binding moiety has enabled the development of compounds with low nanomolar potencies in both BRAF inhibition and cellular assays. These compounds display optimal pharmacokinetic properties that warrant further in vivo investigations.

PYRIDO[2,3-B]PYRAZINE-8-SUBSTITUTED COMPOUNDS AND THEIR USE

The present invention pertains generally to the field of therapeutic compounds for treating proliferative disorders, cancer, etc., and more specifically to certain pyrido[2,3-b]pyrazin-8-substituted compounds, as described herein, which, inter alia, inhibit RAF (e.g., B RAF) activity. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit RAF (e.g., BRAF) activity, to inhibit receptor tyrosine kinase (RTK) activity, to inhibit cell proliferation, and in the treatment of diseases and disorders that are ameliorated by the inhibition of RAF, RTK, etc., proliferative disorders such as cancer (e.g., colorectal cancer, melanoma), etc.

IMIDAZO[4,5-B]PYRIDIN-2-ONE AND OXAZOLO[4,5-B]PYRIDIN-2-ONE COMPOUNDS AND ANALOGS THEREOF AS THERAPEUTIC COMPOUNDS

The present invention pertains to certain imidazo[4,5-b]pyridin-2-one and oxazolo[4,5-b]pyridin-2-one compounds and analogs thereof, which, inter alia, inhibit RAF (e.g., B-RAF) activity, inhibit cell proliferation, treat cancer, etc., and more particularly to compounds of the formula (I): wherein: J is independently -O- or -NRN1-; RN1, if present, is independently -H or a substituent; RN2 is independently -H or a substituent; Y is independently -CH= or -N=; Q is independently -(CH2)j-M-(CH2)k- wherein: j is independently 0, 1 or 2; k is independently 0, 1, or 2; j+k is 0, 1, or 2; M is independently -O-, -S-, -NH-, -NMe-, or -CH2-; each of RP1, RP2, RP3, and RP4 is independently -H or a substituent; and additionally RP1 and RP2 taken together may be -CH=CH-CH=CH-; L is independently: a linker group formed by a chain of 2, 3, or 4 linker moieties; each linker moiety is independently -CH2-,-NRN-, -C(=X)-, or -S(=O)2-; exactly one linker moiety is -NRN-, or: exactly two linker moieties are -NRN-; exactly one linker moiety is -C(=X)-, and no linker moiety is -S(=O)2-; or: exactly one linker moiety is -S(=O)2-, and no linker moiety is -C(=X)-; no two adjacent linker moieties are -NRN-; X is independently =O or =S; each RN is independently -H or a substituent; A is independently: C6-14carboaryl, C5-14heteroaryl, C3-12carbocyclic, C3-12heterocyclic; and is independently unsubstituted or substituted; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, N-oxides, chemically protected forms, and prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit RAF (e.g., B-RAF) activity, to inhibit receptor tyrosine kinase (RTK) activity, to inhibit cell proliferation, and in the treatment of diseases and conditions that are ameliorated by the inhibition of RAF, RTK, etc., proliferative conditions such as cancer (e.g., colorectal cancer, melanoma), etc.
