一般說明
酯酶,又称羧基酯水解酶,是水解酶超家族中的一员。
應用
从猪肝中提取的酯酶已用于揭示紫外可见光谱中的荧光。
该酶(来自 Sigma)已被用于开发一种基于凝胶的替代实验方案,用于水性介质中的珠结合催化活性的筛选。该产品还用于研究化合物 L-缬氨酸-3- {8- [(E)-2- [3-甲氧基苯基]乙烯基] -7-甲基-1-炔丙基黄嘌呤-3-基}丙基酯盐酸盐的性质(MSX-4,一种腺苷 A2A 受体拮抗剂 MSX-2 的氨基酸酯前药)。
猪肝酯酶被用于制药和工业应用中以催化五乙酰儿茶素和表儿茶素的水解。
猪肝酯酶常用于有机化学中的动力学拆分和不对称合成。

The compound L-valine-3-{8-[(E)-2-[3-methoxyphenyl)ethenyl]-7-methyl-1-propargylxanthine-3-yl}propyl ester hydrochloride (MSX-4) was synthesized as an amino acid ester prodrug of the adenosine A2A receptor antagonist MSX-2. It was found to be stable in artificial gastric acid, but readily cleaved by pig liver esterase.
