Cell suspension cultures of Pinus radiata metabolize the antifungal Trichoderma secondary metabolite 6-n-pentyl-2H-pyran-2-one (6PAP) (1) via hydroxylation of the pentyl side chain. Examination of the culture medium following dosing studies with 1 revealed that 79-85% of this bioactive compound had been metabolised after 144 h. At that time, 34-40% of the metabolized dose was recovered as a series of monohydroxylated isomers of 1, the principal metabolite being 5-(2-pyron-6-yl)pentan-5-ol (7).
