Abstract

Chemical investigation on the deep-sea-derived fungus Chaetomium globosum led to the isolation of nine compounds. By extensive analyses of the 1D and 2D NMR as well as HR-ESI-MS spectra, their structures were elucidated as xylariol A (1), 1,3-dihydro-4,5,6-trihydroxy-7-methylisobenzofuran (2), epicoccone B (3), epicoccolide B (4), chaetoglobosin G (5), chaetoglobosin Fex (6), cochliodone A (7), cochliodone B (8), and chaetoviridin A (9), assorting as four phenolics (1-4), two cytochalosans (5-6), and three azaplilones (7-9). Compounds 1-3 were firstly reported from C. globosum. Under the concentrations of 20 μg/mL, 1, 2, and 3 exhibited potent in vitro anti-HIV activity with the inhibition rates of 70 %, 75 %, and 88 %, respectively.
