Abstract

A new inactivated product of ribostamycin (SF-733), 3-N-carboxymethyl ribostamycin, was obtained from the broth of Streptomyces ribosidificus which was grown on a medium containing D-xylose. Detection and some biochemical mechanism of N-carboxymethylation were discussed, and structure of 3-N-carboxymethyl ribostamycin was proposed based on the chemical degradation and synthesis.

摘要

一种新的核糖霉素灭活产物(SF - 733),即3 - N - 羧甲基核糖霉素,是从在含有D - 木糖的培养基上生长的产核糖链霉菌肉汤中获得的。讨论了N - 羧甲基化的检测及一些生化机制,并基于化学降解和合成对3 - N - 羧甲基核糖霉素的结构进行了推测。
