Ieodoglucomides A (1) and B (2), unique glycolipopeptides consisting of an amino acid, a new fatty acid, a succinic acid, and a sugar, were isolated from a Marine-derived bacterium Bacillus licheniformis. The absolute stereochemistry of 1 and 2 was determined by deploying coupling constants, Marfey’s and Mosher’s methods, and literature reviews. Compounds 1 and 2 displayed moderate in vitro antimicrobial
从海洋来源的地衣芽孢杆菌中分离出了碘代葡萄糖苷A(1)和B(2),即由氨基酸,新脂肪酸,琥珀酸和糖组成的独特糖脂肽。1和2的绝对立体化学是通过使用偶联常数,Marfey和Mosher方法以及文献综述来确定的。化合物1和2显示出中等的体外抗菌活性。此外,ieodoglucomide B(2)表现出针对肺癌和胃癌细胞系的细胞毒性活性,其GI 50值分别为25.18和17.78μg/ mL。
