for drug physicochemical property modification based on making derivatives that are substrates for known enzymes. The approach requires knowledge of the enzyme-substrate specificities to select the appropriate derivative. As a class, the digestive enzymes represent possible reconversion sites. It is shown that by using only known specificities of these enzymes, the physicochemical properties of a drug
基于制备作为已知酶的底物的衍生物,开发了用于药物物理化学性质修饰的原理。该方法需要了解酶底物的特异性以选择合适的衍生物。一类消化酶代表可能的转化位点。已经表明,通过仅使用这些酶的已知特异性,可以通过适当的衍生物选择以几乎任何期望的方式修饰药物的物理化学性质,而酶促再生保持有效。该策略适用于制备在体内被激活的稳定的阿司匹林衍生物。在制得的衍生物中,阿司匹林苯丙氨酸乙酯显示出悬浮形式稳定超过4年。还显示在体外存在α-胰凝乳蛋白酶和羧肽酶的酶时,阿斯匹林从衍生物再生。这种对药物物理化学性质进行修饰的生化方法为改善药物功效提供了新的有力依据。
