Abstract

Cladosporine A (1), a new indole diterpenoid alkaloid, was isolated from the extract of a fungal strain Cladosporium sp. JNU17DTH12-9-01. Its structure was elucidated by extensive spectroscopic analysis, and the absolute configurations were determined by electronic circular dichroism (ECD) experiments. This is the first report of the presence of indole diterpenoid alkaloid in the genus Cladosporium. The antimicrobial activities against Staphylococcus aureus 209P, Escherichia coli ATCC0111, Aspergillus niger R330, and Candida albicans FIM709 were evaluated. Compound 1 showed MICs of 4 μg/mL and 16 μg/mL against S. aureus 209P and C. albicans FIM709, respectively.
