The endophytic fungus Fusarium equiseti was isolated from the brown alga Padina pavonica , collected from the Red Sea. The fungus was identified by its morphology and 18S rDNA. Cultivation of this fungal strain in biomalt-peptone medium led to isolation of 12 known metabolites of diketopeprazines and anthraquinones. The organic extract and isolated compounds were screened for their inhibition of hepatitis C virus NS3/4A protease (HCV PR). As a result, the fungal metabolites showed inhibition of HCV protease (IC 50 from 19 to 77 μM), and the fungus was subjected to culture on Czapek's (Cz) media, with a yield of nine metabolites with potent HCV protease inhibition ranging from IC 50 10 to 37 μM. The Cz culture extract exhibited high-level inhibition of HCV protease (IC 50 27.6 μg/mL) compared to the biomalt culture extract (IC 50 56 μg/mL), and the most potent HCV PR isolated compound (Griseoxanthone C, IC 50 19.8 μM) from the bio-malt culture extract showed less of an inhibitory effect compared to isolated ω-hydroxyemodin (IC 50 10.7 μM) from the optimized Cz culture extract. Both HCV PR active inhibitors ω-hydroxyemodin and griseoxanthone C were considered as the lowest selective safe constituents against Trypsin inhibitory effect with IC 50 48.5 and 51.3 μM, respectively.
