While a range of strategies exist to accomplish peptide macrocyclization, they are frequently limited by the need for orthogonal protection or provide little opportunity for structural diversification. We have evaluated an efficient macrocyclization method that employs nucleophilicaromaticsubstitution (SNAr) to create thioether macrocycles. This versatile macrocyclization, orthogonal to conventional
虽然存在一系列实现肽大环化的策略,但它们经常受到正交保护需求的限制,或者几乎没有提供结构多样化的机会。我们评估了一种有效的大环化方法,该方法采用亲核芳香取代 (S NAr) 生成硫醚大环化合物。这种与传统肽合成正交的多功能大环化可以在未受保护的拟肽或具有侧链保护的树脂结合肽的溶液中进行。我们表明,产品中存在的吸电子基团可以进一步用于后续的正交反应,以改变肽的特性或添加辅基。大环化策略应用于黑皮质素配体的设计,生成了一个展示不同亚型选择性的强效黑皮质素激动剂库。
