摘要: Two new carotane-type sesquiterpenes named trichocaranes E (1) and F (2), along with two known ones CAF-603 (3) and trichocarane C (4), were isolated from cultures of the insect pathogenic fungus Isaria fumosorosea. Their structures and relative configurations were elucidated by extensive spectroscopic analysis and X-ray crystallography. Compounds 1-3 showed potent cytotoxic activities against six tumor cell lines MDA, MCF-7, SKOV-3, Hela, A549, HepG2 with IC50 values in a concentration range of 0.1-6.0 mu g/ml. [GRAPHICS]
