Borrelidin A (1) is produced by several species of Streptomyces and within its bioactive scaffold, the vinylic nitrile moiety is essential for activity. We report herein newly discovered members of the borrelidin family, borrelidin F (2), borrelidin G (3), borrelidin H (4) and borrelidin I (5); all were isolated from Streptomyces rochei SCSIO ZJ89 originating from a mangrove-derived sediment sample. These structurally diverse metabolites enabled a number of new structure-activity relationships (SARs) to be identified, especially with respect to the different configurations at the C11-OH and C12-C15 double bonds for which the absolute configurations were determined using spectroscopic methods. Importantly, borrelidin H (4) was found to have a therapeutic window superior to that of borrelidin A (1) in vitro and could inhibit migration of cancer cells.
布雷菲德菌素 A(1)由几种链霉菌产生,在其生物活性支架内,乙烯基腈部分对于活性是必不可少的。我们在此报告布雷菲德菌素家族的新发现成员,布雷菲德菌素 F(2)、布雷菲德菌素 G(3)、布雷菲德菌素 H(4)和布雷菲德菌素 I(5);它们均从红树林来源的沉积物样本中分离得到的链霉菌罗氏 SCSIO ZJ89 中分离得到。这些结构多样的代谢产物使许多新的结构-活性关系(SAR)得以确定,特别是对于 C11-OH 和 C12-C15 双键的不同构型,其绝对构型是使用光谱方法确定的。重要的是,发现布雷菲德菌素 H(4)在体外具有优于布雷菲德菌素 A(1)的治疗窗,可以抑制癌细胞的迁移。
