The molecule is a carboxylic ester obtained by the formal condensation of the secondary hydroxy group of 4-hydroxy-6-[hydroxy(phenyl)methyl]pyridin-2(1H)-one with 3-methylbutanoic acid. It is isolated from the culture broth of Penicillium sp. SPF-32629 and acts as an inhibitor of the enzyme chymase (EC 3.4.21.39). It has a role as an antimicrobial agent, an EC 3.4.21.39 (chymase) inhibitor and a Penicillium metabolite. It is a carboxylic ester, a pyridone and a monohydroxypyridine.
