    • The present invention relates to novel prodrugs of pharmaceutical compounds containing one or more NnullH bonds. More specifically, the present embodiment of the invention relates to prodrugs wherein sulfur-containing promoieties are attached to pharmaceutical compounds which contain one or more NnullH bonds to produce prodrugs containing at least one NnullS bond. These NnullS bond-containing prodrugs could have optimized stability, solubility, cell membrane permeability, pharmacokinetic properties and other pharmaceutical properties over the pharmaceutical compounds from which they are formed, depending upon the nature of the promoiety. Reversion of the prodrug to the parent pharmaceutical compound occurs by the reaction of the prodrugs with thiol molecules such as cysteine, glutathione or any other thiol containing molecule. Further, the present invention relates to methods of making NnullS bond-containing prodrugs of pharmaceutical compounds containing one or more NnullH bonds whereby sulfur-containing promoieties are attached to the parent compounds to create at least one NnullS bond.
    • 本发明涉及含有一个或多个N-H键的药物化合物的新型前体药物。 更具体地说,本发明的本实施方案涉及前药,其中含硫衍生物与含有一个或多个N-H键的药物化合物连接以产生含有至少一个N-S键的前药。 这些含有N-S键的前药可以相对于形成它们的药物化合物具有优化的稳定性,溶解性,细胞膜通透性,药代动力学性质和其它药物性质,这取决于促进因素的性质。 通过前体药物与巯基分子如半胱氨酸,谷胱甘肽或任何其它含硫醇分子的反应,将前药转化为母体药物化合物。 此外,本发明涉及制备含有一个或多个N-H键的药物化合物的含N-S键的前体药物的方法,其中含硫衍生物与母体化合物连接以产生至少一个N-S键。
