- Biocatalysis of capsaicin (1) was performed by Penicillium janthinellum AS 3.510. Nine metabolites including four new compounds were afforded, and their structures were elucidated as (8S)-trans-8-hydroxy-8-hydroxymethyl-N-vanillyl-6-nonenamide (2), 6-hydroxy-8-methyl-N-vanillyl-7-nonenamide (3), trans-8-methoxy-8-methyl-N-vanillyl-6-nonenamide (4), 6-methoxy-8-methyl-N-vanillyl-7-nonenamide (5), dihydrocapsaicin (6), ω-1-hydroxydihydrocapsaicin (7), ω-1-hydroxycapsaicin (8), ω-hydroxycapsaicin (9), N-(4-hydroxy-3-methoxybenzyl)-5-[3-(propan-2-yl)oxiran-2-yl]pentanamide (10) by 1D and 2D NMR and HRESIMS spectra. The biotransformation processes include hydroxylation, methylation, reduction, and epoxylation.
