presented. The data show that human and rat liver fractions were more active than human duodenal mucosa and human blood leukocytes at hydrolysing the compounds. The rank order of the compounds was, however, very similar in the different biological systems. Commercially available pig liver carboxyl esterase and cholesterol esterase both reasonably well predict the rank order in the tissue fractions.
最小化药物系统性副作用的一种方法是设计分子,软性药物,以使其在作用于其药理学目标后迅速代谢失活。水解酶(酯酶,肽酶,脂肪酶,糖苷酶等)是非常适合用于药物灭活的酶,因为它们分布广泛。易酶裂解的酯键的插入可能是使药物的作用更局限在应用部位的一种方法。本研究描述了十四种模型化合物的化学合成,该模型化合物包含通过含酯桥连接至另一个芳环的双环芳族单元。介绍了定义a)水解代谢的组织选择性和b)影响酶促酯裂解速率的分子结构因素的初步尝试。数据显示,人和大鼠的肝脏组分在水解化合物方面比人十二指肠粘膜和人血白细胞更具活性。但是,在不同的生物系统中,化合物的等级顺序非常相似。市售的猪肝羧基酯酶和胆固醇酯酶均能很好地预测组织级分中的等级顺序。
