The lipase from Candida cylindracea (CCL) deacetyles rapidly and selectively all three regioisomer methyl acetoxybenzoates. In the enzymatic hydrolyses of analogous aryl acetoxybenzoates, the difference of reactivity between the acetoxy and benzoyloxy functionalities is reduced and a methoxy group in meta position of the aryl group reverses the reactivity order making the compounds aspirin or aspirin-like
来自Candida cylindracea(CCL)的脂肪酶可快速且选择性地使所有三种区域异构体乙酰氧基苯甲酸甲酯脱乙酰。在类似的芳基乙酰氧基苯甲酸酯的酶水解中,乙酰氧基和苯甲酰氧基官能团之间的反应性差异减小,并且芳基间位的甲氧基反转了反应性顺序,从而使化合物为阿司匹林或类似阿司匹林的前药。苯乙基苯甲酸酯的酶促水解的对映选择性的程度与立体异构中心的位置有关。
