The preparation of N,N-bis(methylsulfonylethoxycarbonyl)insulins is described. In an aequeous buffer at pH 5.8 selectivity of the reaction of insulin with 20 equivalents of N-(methysulfonylethoxycarbonyloxy)succinimide (Msc-ONSu) leads very specifically to N alpha A 1,-N alpha B 1-(Msc)2 - insulin. The product can be isolated in a yield of 60%. Using N alpha A 1-citraconylinsulin the N alpha B 1, NEB29-(Msc)2 -insulin can be prepared in a yield of 40% based on insulin.
本文描述了N,N-双(甲基磺酰基乙氧基羰基)胰岛素的制备方法。在pH值为5.8的水性缓冲液中,胰岛素与20当量的N-(甲基磺酰基乙氧基羰基氧基)琥珀酰亚胺(Msc-ONSu)反应具有选择性,可非常特异性地生成NαA1,-NαB1-(Msc)2-胰岛素。该产物的分离产率可达60%。以NαA1-柠康酰胰岛素为原料,基于胰岛素的产率为40%,可制备出NαB1,NεB29-(Msc)2-胰岛素。
