Cultures of endophytic fungi collected in the Guanacaste Conservation Area
of Costa Rica were screened for antifungal activity. CR377, a new pentaketi
de antifungal agent, was isolated from the culture broth of a fungus, CR377
(Fusarium sp.), that showed potent activity against Candida albicans in th
is assay. The structure of CR377 was established using 1- and 2-D NMR and H
RFABMS.
