In a continuation of our previous investigation on the bioactive entities from this fungus, solid state fermentation was performed in an attempt to diversify the bioactive secondary metabolites. In the present study, five previously unreported polyketides, theissenophenol ( 1 ), theissenepoxide ( 2 ), theissenolactone D ( 3 ), theissenone ( 4 ), and theissenisochromanone ( 5 ), together with the known theissenolactone B ( 6 ), theissenolactone C ( 7 ), and arthrinone ( 8 ), were isolated and characterized through spectroscopic analysis and comparison with the literature data. The configurations of theissenepoxide ( 2 ) and theissenisochromanone ( 5 ) were further corroborated by single-crystal X-ray diffraction data analysis. Theissenone ( 4 ), theissenolactone B ( 6 ), theissenolactone C ( 7 ), and arthrinone ( 8 ) exhibited potent nitric oxide production inhibitory activities in murine brain microglial BV-2 cells with IC50values of 5.0 ± 1.0, 4.5 ± 0.6, 1.1 ± 0.1, and 3.2 ± 0.3 μM, respectively, without any significant cytotoxic effects. © 2021 American Chemical Society and American Society of Pharmacognosy |
