次生代谢物的微生物构建通常基于生物合成基因簇(BGC),并且不同 BGC 来源的中间体的锻造往往被忽视。在这里,我们展示了 Daldinia eschscholziican 中的 dalescone 生物组装线隔离了客体中间体(即在 dalesconol 生物合成基因簇之外产生的结构单元),以形成骨骼上未描述的分子阵列,例如 (+)-dalescone A,它是一种针对 NLRP3 炎症小体激活的有效抑制剂。
Microbial constructions of secondary metabolites are generally biosynthetic gene cluster (BGC)-based, and the forging of different BGC-sourced intermediates tends to be overlooked. Here, we show that the dalesconol bioassembly lines inDaldinia eschscholziican sequester guest intermediates (i.e., building blocks produced outside the dalesconol biosynthetic gene cluster) to form arrays of skeletally undescribed molecules such as (+)-dalescone A, a potent inhibitor against the NLRP3 inflammasome activation.
