diverse mode‐of‐action at the molecular level. By a combination of structure elucidation experiments, the first total synthesis of zelkovamycin and bioassays, the zelkovamycin configuration was determined and its previously proposed molecular structure was revised. The full structure assignment proves zelkovamycin as an additional member of the argyrins with however unique OXPHOS inhibitory properties
天然产物(NPs)是开发药物和化学探针的重要灵感来源。1999年,Ōmura小组报告了对zelkovamycin的宪法解释。尽管目前为止尚未被广泛认识,但该NP与精蛋白NP家族具有结构相似性和差异,后者是一类肽NP,在分子水平上具有抗癌活性和不同的作用方式。通过结合结构阐明实验,首次合成合成的zelkovamycin和生物测定法,确定了zelkovamycin的构型并修改了其先前提出的分子结构。完整的结构证明佐科霉素是精氨酸的另一成员,具有独特的OXPHOS抑制特性。
