Two new indole-diterpenoids, penpaxilloids F and G (1 and 2), along with 11 known analogues (3-13), were isolated from the marine fungus Penicillium sp. ZYX-Z-718. The structures of the new compounds were identified by extensive spectroscopic analyses including HR-ESI-MS, UV, and NMR, as well as theoretical NMR chemical shifts and ECD calculations. Compounds 6 and 10 showed antibacterial activity against Gram-positive bacteria including Staphylococcus aureus, Bacillus subtilis, and MRSA with MIC values ranging from 16.0-32.0 μg/mL.
从海洋真菌青霉菌ZYX-Z-718中分离出两种新的吲哚-二萜类化合物，青霉帕西洛类化合物F和G（1和2），以及11种已知类似物（3-13）。通过包括高分辨电喷雾电离质谱（HR-ESI-MS）、紫外光谱（UV）和核磁共振（NMR）在内的广泛光谱分析，以及理论核磁共振化学位移和电子圆二色光谱（ECD）计算，确定了新化合物的结构。化合物6和10对包括金黄色葡萄球菌、枯草芽孢杆菌和耐甲氧西林金黄色葡萄球菌（MRSA）在内的革兰氏阳性菌显示出抗菌活性，其最低抑菌浓度（MIC）值范围为16.0 - 32.0μg/mL。
