Abstract

A fungal strain named MFF-1 was isolated from the flower of Pyrethrum cinerariifolium. Based on the sequence at the internal transcribed spacer (ITS) region, this strain was identified as a Trichoderma sp. Two new compounds, including a mitorubrin derivative and its potential biogenetic precursor, together with a known compound, were isolated from the cultures of the endophytic fungus. Their structures were established by spectroscopic methods and determined to be (3S*,6R*,7R*)-3,4,5,6,7,8-hexahydro-7-hydroxy-7-methyl-8-oxo-3-[(E)-prop-1-enyl]-1H-isochromen-6-yl 2,4-dihydroxy-6-methylbenzoate (1), named deacetylisowortmin, (E)-2-(hydroxymethyl)-3-(2-hydroxypent-3-enyl)phenol (2), and wortmannin (3). All compounds were assayed for antimicrobial activity. Compound 3 showed activity against Candida albicans and Bacillus cereus.
