Discovery and Optimization of a Novel Series of Potent Mutant B-RafV600E Selective Kinase Inhibitors
摘要:
B-Raf represents an attractive target for anticancer therapy and the development of small molecule B-Raf inhibitors has delivered new therapies for metastatic melanoma patients. We have discovered a novel class of small molecules that inhibit mutant B-Raf(V600E) kinase activity both in vitro and in vivo. Investigations into the structure-activity relationships of the series are presented along with efforts to improve upon the cellular potency, solubility, and phannacokinetic profile. Compounds selectively inhibited B-Raf(V600E) in vitro and showed preferential antiproliferative activity in mutant B-Raf(V600E) cell lines and exhibited selectivity in a kinase panel against other kinases. Examples from this series inhibit growth of a B-Raf(V600E) A375 xenograft in vivo at a well-tolerated dose. In addition, aminoquinazolines described herein were shown to display pERK elevation in nonmutant B-Raf cell lines in vitro.

The invention relates to chemical compounds of the formula (I) or pharmaceutically acceptable salts thereof, which possess B-Raf inhibitory activity and are accordingly useful for their anti cancer activity and thus in methods of treatment of the human or animal body. The invention also relates to processes for the manufacture of said chemical compounds, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of an anti-cancer effect in a warm blooded animal such as man.
