reaction of targeted covalent inhibitors with nucleophilic residues in protein active sites. Herein, we present thiol reactivity studies that support α-methylene-γ-lactams as tunable surrogates for the highly reactive α-methylene-γ-lactones. The reactivity of the α-methylene is modulated via the N substituent, and the reaction rates toward glutathione were determined via mass spectrometry. Density
激酶活性可以通过靶向共价抑制剂与蛋白质活性位点中的亲核残基的反应来可逆或不可逆地调节。在此,我们提出了硫醇反应性研究,支持 α-亚甲基-γ-内酰胺作为高反应性 α-亚甲基-γ-内酯的可调替代物。α-亚甲基的反应性通过 N 取代基进行调节,谷胱甘肽的反应速率通过质谱法确定。硫醇加成到 α-亚甲基-γ-内酰胺的过渡态的密度泛函理论计算表明,使用 M06-2X 泛函与 SMD 溶剂化模型和硫醇甲酯作为模型亲核试剂可靠地预测了 α-亚甲基的相对反应性-γ-内酰胺和准谐波近似提高了实验和计算之间的一致性。
