The design, synthesis and biological activity of new thrombin inhibitors with a pyridinone or pyrazinone core and different heterobicyclic P(1) arginine side-chain mimetics are described. The arginine side-chain mimetics used in this study are (+/-)-4,5,6,7-tetrahydro-2H-indazol-5-ylmethanamine and both enantiomers thereof, (+/-)-4,5,6,7-tetrahydro-1,3-benzothiazole-2,6-diamine and the corresponding
设计,合成和生物活性的新型凝血酶抑制剂具有吡啶酮或吡嗪酮核心和不同的杂环双(P)(1)精氨酸侧链模拟物。在这项研究中使用的精氨酸侧链模拟物是(+/-)-4,5,6,7-四氢-2H-吲唑-5-基甲胺及其两种对映体(+/-)-4,5,6 ,7-四氢-1,3-苯并噻唑-2,6-二胺和相应的R对映体。吡嗪酮系列抑制剂中最有效的化合物25在体外的K(i)为41 nM,对胰蛋白酶和Xa因子的选择性高。
