A new antibacterial 3-monoacyl-sn-glycerol, nostochopcerol (1), was isolated from a cultured algal mass of the edible cyanobacterium Nostochopsis lobatus MAC0804NAN. The structure of compound 1 was established by the analysis of NMR and MS data while its chirality was established by comparison of optical rotation values with synthetically prepared authentics. Compound 1 inhibited the growth of Bacillus subtilis and Staphylococcus aureus at MIC of 50 μg/mL and 100 μg/mL, respectively.
从可食用蓝藻 Nostochopsis lobatus MAC0804NAN 的培养藻块中分离出了一种新的抗菌 3-monoacyl-sn-glycerol, nostochopcerol (1)。化合物 1 的结构是通过核磁共振和质谱数据分析确定的,其手性则是通过与合成的真品进行旋光度比较确定的。化合物 1 抑制枯草杆菌和金黄色葡萄球菌生长的 MIC 值分别为 50 μg/mL 和 100 μg/mL。
