Protease-activated receptor-1 (PAR-1) is a G-coupled receptor activated by alpha-thrombin and other proteases. In this paper we describe the synthesis and the pharmacological evaluation of novel peptide-mimetic antagonists (compounds 1-16) characterized by the presence of new heterocyclic nuclei such as 2-methyl-indole (5- and 6-substituted) and 1,4-benzodiazepine moiety. The new derivatives, tested in order to evaluate
蛋白酶激活受体1(PAR-1)是由α-凝血酶和其他蛋白酶激活的G偶联受体。在本文中,我们描述了新型肽模拟拮抗剂(化合物1-16)的合成和药理学评价,其特征在于存在新的杂环核,例如2-甲基吲哚(5-和6-取代的)和1,4 -苯并二氮杂moiety部分。测试新衍生物以通过使用PAR-1AP诱导的人血小板聚集来评估其拮抗剂效价,在某些情况下(化合物1和4)比参照物更有效。在主动脉环上测试的化合物证实了在聚集测定中获得的结果。
