  2,7-naphthyridinone-based MET kinase inhibitors: A promising novel scaffold for antitumor drug development

  摘要：

  As part of our effort to develop new molecular targeted antitumor drug, a novel 2,7-naphthyridone-based MET kinase inhibitor, 8-((4-((2-amino-3-chloropyridin-4-yl)oxy)- 3-fluorophenyl)amino)-2-(4-fluorophenyl)-2,7-naphthyridin-1(2H)-one (13f), was identified. Knowledge of the binding mode of BMS-777607 in MET led to the design of new inhibitors that utilize novel 2,7-naphthyridone scaffold to conformationally restrain the key pharmacophoric groups (block C). Detailed SAR studies resulted in the discovery of a new MET inhibitor 13f, displaying favorable in vitro potency and oral bioavailability. More importantly, 13f exhibited excellent in vivo efficacy (tumor growth inhibition/TGI of 114% and 95% in 50 mg/kg, respectively) both in the U-87 MG and HT-29 xenograft models. The favorable drug-likeness of 13f indicated that 2,7-naphthyridinone may be used a promising novel scaffold for antitumor drug development. The preclinical studies of 13f are under way.

  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。
