    • Prodrugs having a hydrolyzable carbamate moiety, compositions including the prodrugs, methods of preparing the prodrugs and methods of treatment using the prodrugs are disclosed. The prodrug has the formula DC(X)XR, where D is a biologically active agent, X is O, S or NR , and R is a moiety that modifies various properties of the biologically active agent. The biologically active agent either includes a functional group such as an amide, thioamide, imide, thioimide, urea, thiourea, carbamate, thiocarbamate, sulfonamide, or sulfonimide group, or includes a hydroxy, amine, carboxylic acid or thiol group that is modified to include such a group. An NH group from the biologically active agent can be coupled to an activated form the C(X)XR moiety to form the prodrugs described herein. Relative to a conventional carbamate group, the presence of the additional carbonyl or sulfonyl group makes the carbamate group more susceptible to hydrolysis. The prodrugs are more stable in certain environments than the biologically active agent, and can permit the drugs to be administered orally, in those embodiments where the biologically active agent must otherwise be administered by injection or intraveneous administration.
    • 公开了具有可水解的氨基甲酸酯部分的前药,包括前药的组合物,制备前药的方法和使用前药的治疗方法。 前药具有式DC(X)XR,其中D是生物活性剂,X是O,S或NR,并且R是改变生物活性剂的各种性质的部分。 生物活性剂包括官能团如酰胺,硫代酰胺,酰亚胺,硫代酰亚胺,脲,硫脲,氨基甲酸酯,硫代氨基甲酸酯,磺酰胺或磺酰亚胺基团,或包括羟基,胺,羧酸或硫醇基, 包括这样一个组。 来自生物活性剂的NH基团可以与C(X)XR部分的活化形式偶联以形成本文所述的前药。 相对于常规的氨基甲酸酯基团而言,额外的羰基或磺酰基团的存在使得氨基甲酸酯基团更易于水解。 前药在某些环境下比生物活性剂更稳定,并且可以允许药物以口服方式施用,其中生物活性剂必须以其他方式通过注射或静脉内施用施用。
