| Abstract: Objective To investigate the secondary metabolites of the Penicillium chrysogenum (14XS09-2) isolated from a simple plate sponge Plakortis simplex collected from the Yongxing sea area of Xisha Islands, China. Methods The secondary metabolites were purified by TLC and column chromatography over silica gel, Sephadex LH-20, ODS and HPLC, and their structures were determined by spectroscopic analysis including NMR and MS,and by comparison with the data of literature. Results Ten compounds were isolated from the secondary metabolites of Penicillium chrysogenum (14XS09-2), which were identified as isoroquefortine C(1), meleagrin(2), 2", 3"-dihydrosorbicillin (3), sohirnone A(4 ), sorbicillin (5), rezishanones D (6), N-(2-methoxyphenyl)(7), 2-benzoxazolinone (8), cyclo-(L-Try-L-Pro) (9), Nb-acetyltryptamine (10). Conclusion Compounds 3 and 4 exhibited moderate cytotoxicity against PTP1B with the proliferation inhibition rate of 10.58% and 8.47%, respectively, at the concentration level of 40 μmol·L?1. |
