Covalent, irreversible small-molecule inhibitors that modify the sulfenyl form (i.e., sulfenic acid, RSOH and sulfenamide, RSNR'2) of therapeutically important proteins (particularly kinases and phosphatases) are disclosed, where the compositions include a compound having a substituted aryl or heterocyclic core structure that promotes binding interactions with a specific protein, and a nucleophilic reaction center (carbon, nitrogen, sulfur, or phosphorous) that is capable of forming a covalent bond with a sulfenic acid- or sulfenamide-modified cysteine residue in the protein. Methods for synthesizing these compounds are also disclosed, as well as methods of using them for determining the bioactivity of a chemical composition comprising an active compound toward a specific protein and for determining the potency of an inhibitor against a specific protein.
揭示了用于修饰治疗重要蛋白质(特别是激酶和磷酸酶)的亚硫酰形式(即亚硫酸,RSOH和亚硫酰胺,RSNR'2)的共价、不可逆的小分子抑制剂,其中组合物包括具有取代芳基或杂环核结构的化合物,促进与特定蛋白质的结合相互作用,以及能够与蛋白质中的亚硫酸或亚硫酰胺修饰的半胱氨酸残基形成共价键的亲核反应中心(碳、氮、硫或磷)。还揭示了合成这些化合物的方法,以及使用它们确定包含活性化合物的化学组合物对特定蛋白质的生物活性以及确定抑制剂对特定蛋白质的效力的方法。
