Biosynthetic studies on napyradiomycins were carried out based on the incorporation of [2-13C]acetate and [1,2-13C]acetate. The alignment of acetate units suggested that the B and C rings of napyradiomycins are derived from a pentaketide, while ring A and the side chain may be synthesized from mevalonate.
基于[2-¹³C]乙酸盐和[1,2-¹³C]乙酸盐的掺入,开展了对萘纳霉素的生物合成研究。乙酸盐单元的排列表明,萘纳霉素的B环和C环源自一个五酮化合物,而A环和侧链可能由甲羟戊酸合成。
