structural effects on the release kinetics of a coumarin-based esterase-sensitive prodrug system, two series of compounds with varying structural features of the ester 'trigger' part and the amine 'drug' part were synthesized. The half-lives of the nine model prodrugs in the presence of porcine liver esterase ranged from about 2 min to 190 min. The steric bulkiness of the acyl group seems to have only a
为了研究对香豆素基酯酶敏感的前药系统的释放动力学的结构影响,合成了酯“触发”部分和胺“药物”部分具有不同结构特征的两个系列化合物。在猪肝酯酶存在下,这九种模型前药的半衰期为约2分钟至190分钟。酰基的空间体积似乎对酯酶触发的胺从模型前药中释放的半衰期影响很小。内酯化的速率取决于胺部分的空间和电子性质。
