Chemoselective conjugation is achieved through redox reactivity by reacting an N-transfer oxidant with a thioether substrate in a redox reaction in an aqueous environment to form a conjugation product. In embodiments, Redox-Activated Chemical Tagging (ReACT) strategies for methionine-based protein functionalization. Oxaziridine (Ox) compounds serve as oxidant-mediated reagents for direct functionalization by converting methionine to the corresponding sulfimide conjugation product.
化学选择性共轭是通过氧化还原反应实现的,在
水环境中,N-转移氧化剂与
硫醚底物发生氧化还原反应,形成共轭产物。在实施方案中,氧化还原激活
化学标记(ReACT)策略用于基于蛋
氨酸的蛋白质功能化。Oxaziridine (Ox) 化合物可作为氧化剂介导的试剂,通过将蛋
氨酸转化为相应的亚
硫酰亚胺共轭产物而直接进行功能化。
