(2), were isolated from Streptomyces sp. OUCMDZ-4348. Their structures were elucidated by spectroscopic analysis, quantum chemical calculations, chemical derivatizations, and Mosher’s methods. The sequenced genome of OUCMDZ-4348 revealed the putative biosynthetic gene cluster of cyclamenols. It was proposed that the polycyclic natural products, cyclamenols H–R, might be formed from cyclamenols A and G
从链霉菌中分离出 12 种新的多烯大环内酰胺、仙客来醇 G–R( 1和3–13 )以及已知的类似物仙客来醇 A ( 2 )。 OUCMDZ-4348。它们的结构通过光谱分析、量子化学计算、化学衍生化和莫舍尔方法得以阐明。 OUCMDZ-4348 的基因组测序揭示了假定的仙客来醇生物合成基因簇。有人提出,多环天然产物仙客来酚 H-R 可能是由仙客来酚 A 和 G 通过非酶分子内环加成和氧化环化形成的。
