Discovery of a New Series of Naphthamides as Potent VEGFR-2 Kinase Inhibitors
摘要:
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-beta, 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.
The present invention is directed to a monomer useful in preparing therapeutic compounds. The monomer includes one or more pharmacophores which potentially binds to a target molecule with a dissociation constant of less than 300 μM and a linker element connected to the pharmacophore. The linker element has a molecular weight less than 500 daltons, is connected, directly or indirectly through a connector, to the pharmacophore.
