BRAF is a serine/threonine kinase that is mutated in a range of cancers, including 50-70% of melanomas, and has been validated as a therapeutic target. We have designed and synthesized mutant BRAF inhibitors containing pyridoimidazolone as a new hinge-binding scaffold. Compounds have been obtained which have low nanomolar potency for mutant BRAF (12 nM for compound 5i) and low micromolar cellular potency against a mutant BRAF melanoma cell line, WM266.4. The series benefits from very low metabolism, and pharmacokinetics (PK) that can be modulated by methylation of the NH groups of the imidazolone, resulting in compounds with fewer H-donors and a better PK profile. These compounds have great potential in the treatment of mutant BRAF melanomas.

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.
