Production of phenylacetic acid derivatives and 4-epiradicinol in culture by Curvularia lunata

Phenylacetic acid derivatives 1, 3, 4 and epiradicinol (5) have been isolated from the culture mycelia of Curvularia lunata grown on YMG, a medium consisting of yeast, glucose and malt extract. Compounds 1, 3 and 4 lack antimicrobial and antioxidant properties but 5 is significantly antibacterial. The absolute configuration of the diol in 5 was determined by acetonide derivative methodology.
