Metabolites from the endophytic fungus Phomopsis sp PSU-D15

From the endophytic fungus Phomopsis sp. PSU-D15, three metabolites named as phomoenamide (1), phomonitroester (2) and deacetylphomoxanthone B (3), were isolated together with three known compounds, dicerandrol A (4), (1S,2S,4S)-p-menthane-1,2,4-triol (5) and uridine. Their structures Were elucidated by spectroscopic methods. Phomoenamide (1) exhibited moderate in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Ra. (c) 2007 Elsevier Ltd.
