initially assigned the structure of macrolactone-type compound 1, which was later prepared by two different routes. However, major spectroscopic differences between isolated barmumycin and 1 led to revision of the proposed structure as E-16. On the basis of the synthesis of this new compound, and subsequent spectroscopic comparison of it to an authentic sample of barmumycin, the structure of the natural compound
从海洋放线菌链霉菌(Streptomyces sp)的提取物中分离出巴莫霉素。BOSC-022A被发现对多种人类肿瘤细胞系具有细胞毒性。根据初步的一维和二维1 H和13 C NMR光谱,天然化合物首先被赋予大内酯型化合物1的结构,随后通过两种不同的方法制备。然而,分离的巴莫霉素与1之间的主要光谱差异导致将拟议结构改写为E - 16。在合成这种新化合物的基础上,随后将其与真实的巴莫霉素样品进行光谱比较,确实证实了该天然化合物的结构为E - 16。
