Alpha-haloketones are useful alkylating agents for coupling to sulfhydryl-containing biomolecules. However, they react spontaneously with water, alkali and organic bases and therefore cannot be stored for extended periods of time in aqueous solutions, particularly in the presence of proteins at physiological pH. The present invention provides novel solutions to these problems, however, as novel compounds and compositions comprising protected haloketones are disclosed herein. Methods of preparing and using protected haloketones which are useful in a variety of applications—e.g., in assays and conjugation reactions—are also disclosed herein.
α-卤化酮是一种有用的烷基化剂,可与含巯基的生物大分子偶联。然而,它们会自发地与水、碱和有机碱发生反应,因此不能在水溶液中长期保存,尤其是在生理 pH 值下有蛋白质存在的情况下。然而,本发明为这些问题提供了新的解决方案,因为本发明公开了包含受保护卤化酮的新型化合物和组合物。本发明还公开了制备和使用受保护卤化酮的方法,这些卤化酮可用于多种应用领域,如检测和共轭反应。
