Metyrapone, a potent cytochrome P-450 inhibitor, added at 9 mM to a submerged culture of Streptomyces cinnamonensis caused partial inhibition of total monensin biosynthesis and coproduction of new metabolites, 26-deoxymonensins A and B. The latter was isolated as its 25-O-methyl derivative. Metyrapone was simultaneously reduced to metyrapol. All of these compounds were identified by nuclear magnetic resonance spectroscopy and mass spectrometry.
甲吡酮是一种有效的细胞色素P-450抑制剂,在9 mM的浓度下添加到肉桂链霉菌的深层培养物中,会部分抑制莫能菌素的总生物合成,并共同产生新的代谢产物26-脱氧莫能菌素A和B。后者以其25-O-甲基衍生物的形式被分离出来。甲吡酮同时被还原为甲吡醇。所有这些化合物均通过核磁共振光谱和质谱鉴定。
