Discovery of aminopyridines substituted with benzoxazole as orally active c-Met kinase inhibitors
摘要:
We report the synthesis and biological evaluation of aminopyridines substituted with benzoxazole. The SAR of the aminopyridines was explored to improve the inhibitory activity against c-Met and to decrease hERG affinity. These studies led to the discovery of amide 24 which showed good c-Met inhibitory potency, low affinity to hERG and favorable pharmacokinetic properties in rats. (C) 2010 Elsevier Ltd.
