Abstract
Dehydroepiandrosterone (1) was investigated for biotransformation studies using the plant cell suspension culture of Azadirachta indica A. Juss. for the first time, yielding metabolites 2–6: 5α,3,17-androstanedione (2), 5-androstene-3β,17β-diol (3), 3β-hydroxyandrostan-17-one (4), 3β,11α-dihydroxy-5-androsten-17-one (5), and 3β,7α-dihydroxy-5-androsten-17-one (6), whose structures were solved through modern spectroscopic methods. All five compounds 2–6 have not been reported obtained by this way before. This is a new method to biosynthesize compounds 2–6 employing cultured cells of A. indica. Metabolites 2, 3, and 6 are important biologically active compounds, whereas 4 is a precursor for the production of the 7-hydroxylated compound having antiglucocorticoid and neuroprotective effects.
