Abstract Incorporation experiments with [Me-2H3]methionine, [1-13C]- and [1,2-13C2]- acetate showed that the methyl groups of xanthofusin are derived from methionine, and the remaining carbon atoms are derived from three intact acetate units. Incorporation of 13C-labelled 1,3-dihydroxy-2,4-dimethylbenzene shows that this is a probable intermediate. Three possible pathways are discussed, namely a triketide
摘要 [Me-2H3]甲硫氨酸、[1-13C]-和[1,2-13C2]-乙酸酯掺入实验表明,黄褐素的甲基来源于甲硫氨酸,其余碳原子来源于三个完整的乙酸酯。单位。掺入 13C 标记的 1,3-二羟基-2,4-二甲基苯表明这是可能的中间体。讨论了三种可能的途径,即黄褐素的三酮基来源,通过四酮但失去起始单元的途径,最后,包括具有丙二酸起始单元的三酮基的途径。
