[摘要]:Two new drimane-type sesquiterpenoid ethers of isocitric acid, cryptoporic acids N (1) and O (6), were isolated from the fruiting bodies of Cryptoporus sinensis. Their structures were established by means of spectroscopic methods, including 1D- and 2D-NMR. The cytotoxic activity against a panel of cell lines (A549, MCF-7, PC-3, and PANC-1) was evaluated for all cryptoporic acid derivatives 112 isolated. |
