Three new mycophenolic acid derivatives, penicacids L-N (1-3), together with four known analogues, were isolated from a fungus Penicillium sp. HN-66 derived from a South China Sea marine sediment. The structures of compounds 1-3 were determined on the basis of HR-ESI-MS, NMR (H, C, HSQC and HMBC) data analyses, and comparison of optical rotations. Antimicrobial activities of 1-7 were tested. The results showed that compounds 1-3 and 5-7 had weak inhibitory effects against E. coli ATCC 25922 with the MIC values of 50 μg/mL.
从一株源自中国南海海洋沉积物的青霉菌 Penicillium sp. HN-66 中分离得到了三种新的霉酚酸衍生物，即青霉酸 L-N（1-3），以及四种已知类似物。通过高分辨电喷雾电离质谱（HR-ESI-MS）、核磁共振（H、C、HSQC 和 HMBC）数据分析以及旋光度比较确定了化合物 1-3 的结构。测试了 1-7 的抗菌活性。结果表明，化合物 1-3 和 5-7 对大肠杆菌 ATCC 25922 具有较弱的抑制作用，最低抑菌浓度（MIC）值为 50 μg/mL。
