  Biotransformation of dydrogesterone (1) by using cell suspension cultures of Azadirachta indica yielded a metabolite 20R-hydroxy-9β,10α-pregna-4,6-diene-3-one (2). The structure of this compound was deduced on the basis of various spectroscopic techniques.

  Nine secondary metabolites-artemetin (1), casticin (2), 3-hydroxy-5,6,7,4'-tetramethoxy flavone U(3), penduletin (4), p-hydroxybenzoic acid (5), methyl 3,4-dihydroxybenzoate (6), methyl isovanillate (7), vanillic acid (8), and 3,4-dihydroxybenzoic acid (9)-were isolated from a folkloric medicinal plant, Vitex agnus-castus. The structures of compounds 1-9 were identified using spectroscopic techniques. Compound 7 was isolated for the first time from this plant. These compounds were screened for their antioxidant activity. Compounds 6 and 9 exhibited significant activity against the DPPH free radical.

  Biotransformation of danazol (17β-hydroxy-17 α-pregna-2,4-dien-20-yno-[2,3-d] isoxazole) (1) on fermentation with Fusarium solani yielded 17β-hydroxy-2-(hydroxymethyl)-17α -pregn-4-en-20-yn-3-one (2) and 17β-hydroxy-2-(hydroxymethyl)-17α-pregna-1,4-dien-20-yn-3-one (3), while the fermentation of 1 with Gibberella fujikuorii yielded compound 2 only. The structures of these compounds were deduced on the basis of modern spectroscopic techniques. Prolyl endopeptidase inhibition activities of danazol (1) and its transformed products 2 and 3 are also studied.
