Microsomal esterases were used in the study of the in vitro enzymic hydrolysis of the ester bond in alkyl(2-benzoyloxyethyl)dimethylammonium bromides. These compounds are potential "soft" disinfectants, easily biodegradable to nontoxic biologically inactive hydrolytic products, namely substituted choline and benzoic acid. Formation of the latter product was used to monitor the kinetics of the reaction. It has been found that the rate of enzymic hydrolysis is substantially influenced by different length of the alkyl chain on the ammonium nitrogen. At the same time, interspecies (rat-mouse) and interorgan (liver-kidney) variability has been observed.
在研究中使用了微粒体酯酶来研究烷基(2-苯甲酰氧乙基)二甲基铵溴化物酯键的体外酶解。这些化合物是潜在的“软”消毒剂,容易生物降解为无毒的生物不活性水解产物,即取代胆碱和苯甲酸。后者产物的形成用于监测反应的动力学。发现酶解速率受铵氮上烷基链长度不同的显著影响。同时,观察到了种间(大鼠-小鼠)和器官间(肝脏-肾脏)的变异性。
