class of prodrug-type agents. In vitro experiments using three kinds of purified carboxylesterase isozymes from the liver microsomes of rat, pig, and human demonstrated that these derivatives were efficiently metabolized by enzymes compared with CPT-11.
制备了五种带有长链脂肪酸酯的(20S)-10-羟基喜树碱衍生物,用于开发新型的前药型药物。使用来自大鼠,猪和人的肝微粒体的三种纯化的羧酸酯酶同工酶进行的体外实验表明,与CPT-11相比,这些衍生物可通过酶有效地代谢。
