Isolation of 2-pyridone alkaloids from a New Zealand marine-derived penicillium species.
Fermentation of a Penicillium sp. isolated from a surface-sterilized thallus segment of the brown alga Xiphophora gladiata, collected from Macrocarpa Point, Otago, New Zealand, in half-strength potato dextrose broth led to the isolation and characterization of three alkaloids: the known N-hydroxy-2-pyridone, PF1140 (1), and two new 2-pyridones, 2 and 3.
