Three New Antibacterial Mycophenolic Acid Derivatives from the Marine‐Derived Fungus Penicillium sp. HN‐66

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 (1H, 13C, HSQC and HMBC)...
