A series of chemically stable TXA2/PGH2 analogues modeled after the structure of the natural products was prepared in search of useful inhibitors of TXA2/PGH2-mediated pathophysiology. Each of the 16 isomers implied in structure 1 was prepared in chiral form and evaluated for activity in vitro in platelets and smooth muscle. Depending on relative side chain and carbinol stereochemistry, TXA2/PGH2 agonist
为了寻找有用的TXA2 / PGH2介导的病理生理抑制剂,制备了一系列以天然产物的结构为模型的化学稳定的TXA2 / PGH2类似物。以手性形式制备结构1所示的16种异构体,并评估其在血小板和平滑肌中的体外活性。根据相对的侧链和甲醇的立体化学,观察到TXA2 / PGH2激动剂和拮抗剂,以及令人惊讶的是PGD2 / PGI2激动剂活性。具有1所示的α杂环的对映体通常比其镜像异构体更有效。
