Biosynthesis of anthraquinone derivatives in a Sesamum indicum hairy root culture

In order to investigate the intermediacy of 2-(4-methylpent-3-en-1-yl)anthraquinone (MPAQ), a possible intermediate for the biosynthesis of anthraquinone derivatives in sesame (Sesamum indicum), 2H-labeled MPAQ was administered to a hairy root culture of S. indicum. Efficient conversion of fed MPAQ to 2-[(Z)-4-methylpenta-1,3-dien-1-yl]an-thraquinone ((Z)-MPDEAQ) was observed. Furthermore, administration experiment with 2H-labeled 2-geranyl-1,4-naphthohydroquinone, another possible intermediate, showed that it was converted to MPAQ and (Z)-MPDEAQ. The results clearly demonstrated that these substrates are the actual precursors for the production of (Z)-MPDEAQ. In contrast, neither MPAQ nor 2-geranyl-1,4-naphtho-hydroquinone was converted to anthrasesamone B and 2,3-epoxyanthrasesamone B, other anthraquinone derivatives in the hairy roots, suggesting that these substrates may not be the common precursors in the biosynthesis of anthraquinone derivatives.

A comparison of the oxidation of naphthalene and its d8-derivative by peracetic acid catalysed by Mn3+ tetranitrotetra-tert-butyltetraazaporphine allowed us to refine both the mechanisms of 1,4-naphthoquinone and 1-naphthol formation and the structures of the final products of 1-naphthol oxidation.
