摘要: The new natural product 4-hydroxy-deacety1-18-deoxycytochalasin H (1), together with the known deacety1-18-deoxycytochalasin H (2) and 18-deoxycytochalasin H (3) were obtained from the endophytic fungus Trichoderma harzianzim isolated from leaves of Cola nitida. The structure of the new compound was unambiguously determined by ID and 2D NNW. spectroscopy, and by HRESIMS measurements, as well as by comparison with the literature. Compounds 1-3 showed potent cytotoxic activity against the murine lymphoma (L5178Y) cell line and against human ovarian cancer (A2780 sens and A2780 CisR) cell lines (IC50 0.19-6.97 mu M). The A2780 cell lines included cisplatin-sensitive (sens) and -resistant (R) cells.
