Abstract

Inhibition of VEGFR-2 signaling pathway has already become one of the most promising approaches for the treatment of cancer. In this study, we describe the design, synthesis, and biological evaluation of a new series of naphthamides as potent inhibitors of VEGFR-2. Among these compounds, 14c exhibited high VEGFR-2 inhibitory potency in both enzymatic and HUVEC cellular proliferation assays, with IC50 values of 1.5 and 0.9 nM, respectively. Kinase selectivity profiling revealed that 14c was a multitargeted inhibitor, and it also exhibited good potency against VEGFR-1, PDGFR-β, and RET. Furthermore, 14c effectively blocked tube formation of HUVEC at nanomolar level. Overall, 14c might be a promising candidate for the treatment of cancer.
