Their kinase modulatory effects on FGFR-1, VEGFR-2, PDGFR-β and c-KIT were evaluated by the caliper mobility shift assay. Introduction of cycloalkyl into the pyrimidine linker of pazopanib almost abolished the four kinases inhibitory potency of compounds 2 and 3, but surprisingly, resulted in good activation effects on FGFR-1. Compounds 3d and 3g showed double-digit, nanomolar, selective activation effects on FGFR-1, and could be classified as first-generation small molecular activators of FGFR-1 kinase.展开更多
