A new quinazolinone alkaloid named peniquinazolinone A ( 1 ), as well as eleven known compounds, 2-(2-hydroxy-3-phenylpropionamido)- N -methylbenzamide ( 2 ), viridicatin ( 3 ), viridicatol ( 4 ), (±)-cyclopeptin ( 5a / 5b ), dehydrocyclopeptin ( 6 ), cyclopenin ( 7 ), cyclopenol ( 8 ), methyl-indole-3-carboxylate ( 9 ), 2,5-dihydroxyphenyl acetate ( 10 ), methyl m -hydroxyphenylacetate ( 11 ), and conidiogenone B ( 12 ), were isolated from the endophytic Penicillium sp. HJT-A-6. The chemical structures of all the compounds were elucidated by comprehensive spectroscopic analysis, including 1D and 2D NMR and HRESIMS...
