Abstract
Rhizoleucinoside (1), a unique rhamnolipid-amino alcohol hybrid, was isolated from the rhizobial symbiont bacterium Bradyrhizobium sp. BTAi1. Compound 1 features a rare rhamnolipid core attached to an unprecedented leucinol moiety. Its structure and absolute configuration were determined by spectroscopic analysis, tandem mass spectrometry, chemical degradation, and application of the Marfey's method. Compound 1 possesses moderate cytotoxicity to BV-2 murine microglia and highly aggressive proliferating immortalized (HAPI) rat microglia cells.
摘要
根瘤菌亮氨酸苷（1）是一种独特的鼠李糖脂 - 氨基醇杂合物，从根瘤菌共生细菌慢生根瘤菌属BTAi1中分离得到。化合物1具有一个罕见的鼠李糖脂核心，连接着一个前所未有的亮氨醇部分。其结构和绝对构型通过光谱分析、串联质谱、化学降解以及马尔费方法确定。化合物1对BV - 2小鼠小胶质细胞和高度侵袭性增殖永生化（HAPI）大鼠小胶质细胞具有中等细胞毒性。
