ABSTRACT
We herein disclose a novel chemical series of benzimidazole-ureas as inhibitors of VEGFR-2 and TIE-2 kinase receptors, both of which are implicated in angiogenesis. Structure-activity relationship (SAR) studies elucidated a critical role for the N1 nitrogen of both the benzimidazole (segment E) and urea (segment B) moieties. The SAR results were also supported by the X-ray crystallographic elucidation of the role of the N1 nitrogen and the urea moiety when the benzimidazole-urea compounds were bound to the VEGFR-2 enzyme. The left side phenyl ring (segment A) occupies the backpocket where a 3-hydrophobic substituent was favored for TIE-2 activity.
