| Aim There are a number of theories on which organisms provide the most interesting bioactive metabolites. In this study, we discuss the biochemical activities of the marine-derived endophyte , isolated from the Egyptian Red Sea algae. Methods The fungus was isolated as an endophyte from the Egyptian Red Sea brown alga . The fungus was identified by a morphological method and 18S rDNA sequence comparison. Chemical constituents were isolated using chromatographic techniques. Results and conclusion Cultivation of this fungus in Czapek’s peptone media led to the isolation of five known metabolites: sterigmatocystin (), emericellin (), cordycepin (), ergosterol peroxide (), and myristic acid () from the ethyl acetate extract of the culture broth. The structures were elucidated on the basis of NMR spectroscopic analysis and mass spectrometry. The ethyl acetate extract and the isolated compounds were tested for antimicrobial properties, activity against cancer cell lines, and inhibition of the hepatitis C virus protease. | ||||
