An improved version of the J-based NMR configurational analysis of flexible organic molecules, that relies on extensive use of HSQC-TOCSY spectra, was applied to the stereochemical study of sphinxolide, a potent anti-tumor marine macrolide acting on cell microfilaments that has lately proven to circumvent multi-drug-resistance (MDR) in cancer cells. NMR data allowed stereochemical assignment of all
依赖于广泛使用 HSQC-TOCSY 光谱的柔性有机分子的基于 J 的 NMR 构型分析的改进版本被应用于狮身人面像的立体化学研究,一种有效的抗肿瘤海洋大环内酯类作用于细胞微丝,最近已被证明可以规避癌细胞中的多药耐药性(MDR)。NMR 数据允许对除 C18-C19 单元之外的所有分子片段进行立体化学分配,其构型必须通过化学/降解方法解决。
