Various bispilocarpic acid diesters (double prodrugs of pilocarpine) were synthesized, and their in vitro esterase catalyzed hydrolysis was evaluated in diluted human plasma, rabbit cornea homogenate, and specific butyrylcholinesterase solution. The structural changes greatly affected the rate of enzymatic hydrolysis of the prodrugs. Bispilocarpic acid with 2 cyclopropane substituents was the most
合成了多种双棕榈酸二酯(毛果芸香碱的双前体药物),并在稀释的人血浆,兔角膜匀浆和特定的丁酰胆碱酯酶溶液中评估了其体外酯酶催化的水解作用。结构变化极大地影响了前药的酶促水解速率。具有两个环丙烷取代基的双棕榈酸是最稳定的衍生物,而具有两个环丁烷取代基的双棕榈酸是最不稳定的衍生物。带电荷的双棕榈酸二酯的水解比未改变的形式更慢。由于涉及的酶系统多种多样,因此很难比较从不同血浆和角膜匀浆批次获得的结果。这种多样性也使得比较不同实验室之间的结果变得困难。
