be useful for the biotransformation of sesquiterpene lactones (SLs), leading to unusual structural changes that modify their biological activities, and other transformations mimic their biosynthetic pathways, generating evidences for the proposed biogenesis. Eight filamentous fungi were screened for their ability to transform different SLs (1 - 9), and microbial reactions yielded compounds 10 - 17, which
生物转化是一种经济上和生态上可行的技术,已被用于修饰许多类生物活性产品的结构。一些真菌可能对倍半萜内酯(SLs)的生物转化有用,导致异常结构改变,从而改变其生物活性,而其他转化则模仿其生物合成途径,从而为拟议的生物发生提供证据。筛选了八种丝状真菌转化不同SL的能力(1-9),微生物反应产生的化合物10-17反过来又被分离为天然产物,从而模拟了它们的生物合成。根据NMR和MS光谱分析鉴定了它们的结构。SL 1、4、6、7和9及其生物转化产物的细胞毒性(10、14,
