摘要： Five new meroterpenoids, chrodrimanins O-S (1-5), as well as a known one (6), were isolated from the fermentation broth of Penicillium sp. SCS-ICED09 isolated from a marine worm, Sipunculusnudus, from Haikou Bay, China. The structures including the absolute configurations of the new compounds were unambiguously elucidated by spectroscopic data and ECD spectra analysis along with quantum ECD calculations. Among them, compound 1 represents the first example of an unusual trichlorinated meroterpenoid with an unique dichlorine functionality. Compounds 1 and 4-6 displayed inhibitory activity of protein tyrosine phosphatase 1B (PTP1B) with IC50 values of 71.6, 62.5, 63.1, and 39.6 mu M, respectively, and showed no apparent activity against three tumor cell lines (A549, HepG2, and Hela) and human umbilical vein endothelial cells (HUVEC) at 10 mu M.
