Abstract
Forazoline A is a structurally complex PKS-NRPS hybrid produced by marine-derived sp. During the course of studies highlighting the application of IFS analysis as a powerful tool for natural products analysis, we were alerted to an earlier misinterpretation with respect to forazoline A structure elucidation. In particular, IFS reveals that forazoline A contains a thioketone moiety rarely seen in secondary metabolites and, thus, constitutes an even more intriguing structure than originally thought.
摘要
Forazoline A 是一种结构复杂的 PKS-NRPS 杂合产物，由海洋来源的 sp. 产生。在强调 IFS 分析作为天然产物分析有力工具的应用研究过程中，我们注意到以前对 forazoline A 结构解析的一个误解。特别是，IFS 揭示了 forazoline A 含有一个硫酮部分，这在次级代谢产物中很少见，因此，它的结构比最初认为的更加有趣。
