Antifungal macrocyclic polylactones from Penicillium verruculosum.

Abstract

Three macrocyclic polylactones have been isolated from Penicillium verruculosum. Two were found to be novel and the third to be identical with NG-012(1). Their structures were elucidated by spectroscopic and chemical methods. A full assignment of 1H- and 13C-resonances in acetone-d6 are given for all three compounds. The compounds show antifungal activity.
