scaffold has been proposed as a novel lead structure of MET inhibitors by our group. To broaden the application of this new scaffold, a series of 8-amino-substituted 2-phenyl-2,7-naphthyridin-1(2H)-one derivatives were designed and synthesized. Preliminary biological screening resulted in the discovery of a new lead of c-Kit and VEGFR-2 kinase inhibitors. Compound 9k exhibited excellent c-Kit inhibitory activity
我们小组已提出 2,7-萘啶酮支架作为 MET 抑制剂的新型先导结构。为了扩大这种新支架的应用,设计并合成了一系列 8-氨基取代的 2-苯基-2,7-萘啶-1(2H)-one 衍生物。初步生物筛选导致发现了 c-Kit 和 VEGFR-2 激酶抑制剂的新先导。化合物9k表现出优异的c-Kit抑制活性,IC50值为8.5nM,即比化合物3(IC50为329.6nM)强38.8倍。此外,化合物10l 和10r 表现出良好的VEGFR-2 抑制活性,IC50 值分别为56.5 和31.7 nM,即它们比化合物3(IC50 为279.9 nM)强5.0-8.8 倍。分子对接实验进一步深入了解新先导化合物与 c-Kit 和 VEGFR-2 激酶的结合相互作用。在这项研究中,8-氨基取代的 2-苯基-2,7-naphthyridin-1(2H)-one 支架被确定为 c-Kit 和 VEGFR-2 激酶抑制剂的新先导结构。
