The epipolythiodiketopiperazine (ETP) alkaloids are a highly complex class of natural products with potent anticancer activity. Herein, we report the application of a flexible and scalable synthesis, allowing the construction of dozens of ETP derivatives. The evaluation of these compounds against cancer cell lines in culture allows for the first expansive structure-activity relationship (SAR) to be defined for monomeric and dimeric ETP-containing natural products and their synthetic cognates. Many ETP derivatives demonstrate potent anticancer activity across a broad range of cancer cell lines, and kill cancer cellsviainduction of apoptosis. Several traits thatbode well for the translational potential of the ETP class of natural products includeconcise and efficient synthetic access, potent induction of apoptotic cell death, activity against a wide range of cancer types, and a broad tolerance for modifications at multiple sitesthat should facilitate small-molecule drug development, mechanistic studies, and evaluation .
表硫代二酮哌嗪(ETP)生物碱是一类具有强大抗癌活性的高度复杂的天然产物。在此,我们报道了一种灵活且可扩展的合成方法的应用,该方法能够构建数十种ETP衍生物。对这些化合物在培养的癌细胞系中的评估,使得首次能够为含单体和二聚体ETP的天然产物及其合成类似物定义广泛的构效关系(SAR)。许多ETP衍生物在广泛的癌细胞系中均表现出强大的抗癌活性,并通过诱导凋亡来杀死癌细胞。对ETP类天然产物的转化潜力来说预示良好的几个特性包括简洁高效的合成途径、对凋亡性细胞死亡的有效诱导、对多种癌症类型的活性以及对多个位点修饰的广泛耐受性,这应有助于小分子药物开发、机理研究和评估。
