Abstract

Abstract: Marine derived fungus has gained increasing ground in the discovery of novel lead compounds with potent biological activities including anti‐inflammation. Here, we first report the characterization of one new sorbicillinoid (1 ) and fourteen known compounds (2 –15 ) from the ethyl acetate (AcOEt) extract of a cultured mangrove derived fungus Penicillium sp. DM815 by UV, IR, HR ESI‐Q‐TOF MS, and NMR spectra. We then evaluated the anti‐inflammatory effects of eleven sorbicillinoids (1 –11 ) using cultured macrophage RAW264.7 cells. The results show that compound 9, and to a lesser degree compound 5, significantly inhibited the Gram‐negative bacteria lipopolysaccharide (LPS)‐induced upregulation of the inducible nitric oxide synthase (iNOS). Consistently, compounds 5 and 9 significantly reduced the level of nitric oxide (NO), the product of iNOS, induced by LPS. We further show that these two compounds dose‐dependently inhibited LPS‐triggered iNOS expression and NO production, but had no effect on proliferation of RAW264.7 cells in the presence of LPS. In conclusion, our study identifies novel and known sorbicillinoids as potent anti‐inflammatory agents, holding the promise of developing novel anti‐inflammation treatment in the future. Abstract :
