containing the 1-amino cyclohexa-2,5-diene moiety is an inhibitor of 7;8-diaminopelargonic acid aminotransferase, a pyridoxal phosphate (PLP) dependent enzyme involved in biotin biosynthesis. The postulated mechanism implies the aromatisation of the Schiff base formed between PLP and amiclenomycin. Aromatic adducts have been obtained by heating PLP with amiclenomycin and other related 1-amino cyclohexa-2
Amiclenomycin是一种含有1-氨基环己2,5-二烯部分的天然产物,是7; 8-二氨基壬酸氨基转移酶(一种参与生物素生物合成的吡s醛磷酸酯(PLP)依赖性酶)的抑制剂。推测的机理暗示了在PLP和氨氯霉素之间形成的席夫碱的芳构化。芳香族加合物是通过将PLP与氨霉素和其他相关的1-氨基环己2,5-二烯加热而获得的。它们通过紫外可见光谱和ESI质谱法进行了全面鉴定,并为鉴定酶衍生产物提供了标准。
