of agents that may selectively inhibit the effects of thrombin on cells, without affecting fibrin formation. In this regard, we have synthesized a number of 1,4-disubstituted piperazines which are designed to be analogues of thrombin receptor activating peptides (TRAP) and carry the pharmacophoric features of Phe and Arg residues present in the active pentapeptide SFLLR. These compounds were tested
当发生血管损伤时,局部血栓形成和血管收缩可保护血管,但当动脉粥样硬化斑块破裂时可能有害。最近,血小板凝血酶受体的鉴定为试剂的开发打开了一个新领域,该试剂可以选择性地抑制凝血酶对细胞的作用,而不影响血纤蛋白的形成。在这方面,我们已经合成了许多1,4-二取代的哌嗪,它们被设计为凝血酶受体激活肽(TRAP)的类似物,并具有活性五肽SFLLR中存在的Phe和Arg残基的药效学特征。这些化合物在大鼠主动脉松弛试验和血小板聚集研究中进行了测试,其生物学活性与对凝血酶受体的直接作用一致。此外,
