摘要

雷帕霉素是一种大环内酯类抗生素，具有抗真菌、免疫抑制、抗肿瘤和延长寿命等活性。为了增加其结构多样性，对雷帕霉素进行了微生物转化。枯草芽孢杆菌CGMCC7764在雷帕霉素的微生物转化培养基中显示了3种以上的转化化合物。通过核磁共振和质谱分析，确定主要化合物为43-O-（β-D-葡萄糖苷）-雷帕霉素。这种化合物对肿瘤生长有抑制作用，其活性与雷帕霉素相似。

43-O-(β-D-glucoside)-rapamycin, a microbial conversion product by Bacillus subtilis CGMCC7764

Abstract Rapamycin is a macrolide antibiotic with antifungal, immunosuppressive, antitumor, and lifespan-extension activities etc. In order to increase its structural diversity, microbial transformation of rapamycin was conducted. More than 3 converted compounds were shown in the microbial conversion culture of rapamycin by Bacillus subtilis CGMCC7764. By extensive NMR and MS spectroscopic analyses, the major compound was identified as 43-O-(β-D-glucoside)-rapamycin. This compound has an inhibitory effect on tumour growth, and its activity is similar to rapamycin.
