Evidence for involvement of ketoglutarate in the biosynthesis of Canthin-6-one from cell cultures of Ailanthus altissima.
(13)C enrichments at C-3, C-4, C-5 and C-6 of canthin-6-one from cell cultures of Ailanthus altissima supplemented with [1-(13)C], [2-(13)C] and [1,2-(13)C] acetate, give evidence of the involvement of ketoglutarate as an intact precursor in the biosynthetic pathway.
