Herein, we embarked on a structural optimization campaign aiming at the discovery of second generation anti-angiogenesis agents with our previously reported BPS-7 as lead compound. A library of 27 compounds has been afforded based on the highly conserved ATP-binding pocket of VEGFR-2, TIE-2, and EphB4. Several title compounds exhibited simultaneous inhibitory effects against three angiogenic RTKs. These compounds with a 'triplet' inhibition profile have been identified as novel anti-angiogenic and Anticancer agents. The representative VDAU11 displayed prominent anti-angiogenic and Anticancer potency and could be considered as a candidate for further optimization. These results indicate that N-(pyridin-2-yl)acrylamide could serve as a novel hinge-binding group of triple inhibitors.
