Seven new formamido-diterpenes, cavernenes A-D (1-4), kalihinenes E and F (5-6), and kalihipyran C (7), together with five known compounds (8-12), were isolated from the South China Sea sponge Acanthella cavernosa. Structures were established using IR, HRESIMS, 1D and 2D NMR, and single X-ray diffraction techniques. The isolated compounds were assessed for their cytotoxicity against a small panel of human cancer cell lines (HCT-116, A549, HeLa, QGY-7701, and MDA-MB-231) with IC(50) values in the range of 6-18 μM. In addition, compound 9 showed weak antifungal activity against Trichophyton rubrum and Microsporum gypseum with MIC values of 8 and 32 μg/mL, respectively, compound 10 displayed weak antifungal activity against fungi Candida albicans, Cryptococcus neoformans, T. rubrum, and M. gypseum with MIC values of 8, 8, 4, and 8 μg/mL, respectively.
从南海海绵 Acanthella cavernosa 中分离得到了 7 种新的甲酰胺二萜类化合物 cavernenes A-D（1-4）、kalihinenes E 和 F（5-6）以及 kalihipyran C（7），以及 5 种已知化合物（8-12）。结构通过 IR、HRESIMS、1D 和 2D NMR 以及单晶 X 射线衍射技术确定。对分离得到的化合物进行了人癌细胞系（HCT-116、A549、HeLa、QGY-7701 和 MDA-MB-231）的细胞毒性评估，IC50 值在 6-18 μM 范围内。此外，化合物 9 对红色毛癣菌和石膏样小孢子菌具有较弱的抗真菌活性，MIC 值分别为 8 和 32 μg/mL，化合物 10 对白色念珠菌、新型隐球菌、红色毛癣菌和石膏样小孢子菌具有较弱的抗真菌活性，MIC 值分别为 8、8、4 和 8 μg/mL。
