or peripheral arterial diseases. Previously, we found a series of octahydroindene analogues to have high potency on PAR1 and no significant cytotoxicity but poor metabolic stability in human and rat liver microsomes. We have designed and synthesized fused 6/5 heterobicycle analogues with octahydrocyclopenta[c]pyridine or octahydrocyclopenta[c]pyran core scaffold by the insertion of heteroatom at C5
摘要
蛋白酶激活受体 1 (PAR1) 被认为是一种有前景的抗血小板靶点,可预防既往心肌梗死或外周动脉疾病患者的血栓性心血管事件。此前,我们发现一系列八氢
茚类似物对 PAR1 具有高效能,在人和大鼠肝微粒体中没有显着的细胞毒性,但代谢稳定性较差。我们通过在八氢
茚环的 C5 处插入杂原子,设计并合成了具有八氢
环戊二烯 [c]
吡啶或八氢
环戊二烯 [c]
吡喃核心支架的稠合 6/5 杂双环类似物,旨在提高代谢稳定性。与八氢
茚相比,两种杂双环类似物的代谢稳定性都得到了显着改善,而没有显着降低活性。
