摘要 使用 α-胰凝乳蛋白酶解析 (RS)-2-苄基琥珀酸二乙酯。然后对这两种对映体进行精制,得到 (S)-(+) 和 (R)-(−)-3-苄基-N-[(甲磺酰基)氧基]琥珀酰亚胺,随后测定了这两种对映体对人白细胞弹性蛋白酶的抑制活性。 R 和 S 异构体的 k 2 K I 值分别为 330 和 1500 m− 1 s− 1。
Abstract (RS)-Diethyl-2-benzylsuccinate was resolved using α-chymotrypsin. The two enantiomers were then elaborated to yield (S)-(+) and (R)-(−)-3-benzyl-N-[(methylsulfonyl) oxy] succinimide and the inhibitory activity of the two enantiomers toward human leukocyte elastase was subsequently determined. The k 2 K I values for the R and S isomers were found to be 330 and 1500 m− 1 s− 1, respectively.
