Structurally novel thrombin receptor (protease activated receptor 1, PAR-1) antagonists based on the natural product himbacine are described. The prototypical PAR-1 antagonist 55 showed a Ki of 2.7 nM in the binding assay, making it the most potent PAR-1 antagonist reported. 55 was highly active in several functional assays, showed excellent oral bioavailability in rat and monkey models, and showed
描述了基于天然产物hibacine的结构新颖的凝血酶受体(蛋白酶激活受体1,PAR-1)拮抗剂。原型PAR-1拮抗剂55在结合试验中的Ki值为2.7 nM,使其成为最有效的PAR-1拮抗剂。55在几种功能测定中具有很高的活性,在大鼠和猴子模型中显示出极好的口服生物利用度,并在口服后在食蟹猴中显示出激动剂诱导的离体血小板聚集的完全抑制。
