Liguzinediol (LZDO) ester prodrugs 3–5 were synthesized and evaluated in vitro and in vivo for their potential use in prolonging the half-life of the parent drug LZDO (1a) in vivo. Prodrugs 3–5 were found to display a potent positive inotropic effect on the myocardium, without the risk of arrhythmia. Prodrugs 3–5 rapidly underwent enzymatic hydrolysis to release the parent compound LZDO in 1–3 h in rat liver microsomes and rat plasma. The half-life of the parent compound was prolonged after intragastric administration of prodrug 3, which was found to be a superior prodrug candidate for increasing myocardial contractility.
我们合成了麦角二醇(LZDO)酯原药 3-5,并对其在体外和体内延长母药 LZDO(1a)半衰期的潜在用途进行了评估。研究发现,原药 3-5 对心肌具有强效的正性肌力作用,且无心律失常风险。原药 3-5 在大鼠肝脏微粒体和大鼠血浆中迅速发生酶水解,在 1-3 小时内释放出母体化合物 LZDO。胃内给药原药 3 后,母体化合物的半衰期延长,而原药 3 是增强心肌收缩力的最佳候选原药。
