  Synthesis and Biological Evaluation in Human Monocyte-Derived Macrophages of N-(N-Acetyl-l-cysteinyl)-S-acetylcysteamine Analogues with Potent Antioxidant and Anti-HIV Activities

  摘要：

  We synthesized a series of N-(N-acetyl-L-eysteinyl)-S-acetylcysteamine (10) analogues bearing various acyl groups on thiol cysteine or cysteamine residues, to investigate the structure-activity relationship for pro-GSH and anti-HIV properties in human macrophages. The S-substituents were ranked in the following order of efficacy: H greater than or equal to acetyl > isobutyryl > pivaloyl > benzoyl. We found that none of these derivatives had pro-GSH or antiviral activities in vitro higher than that of 10, but several displayed similar levels of anti-HIV activity, making them possible candidates for use as adjuvant therapies in conjunction with HAART, for treating neurological aspects of HIV infection.

  The invention concerns compounds of general formula (I) (wherein R and R′ represent an alkyl radical or an aryl group and R″ is hydrogen or a CO—R1 group wherein R1 is an alkyl radical or an aryl group; and the dimers formed by the disulphide bond from one and/or the other of the two sulphur atoms of the compounds of general formula (I); and the corresponding thiazolidin forms), the methods for preparing them and uses thereof. More particularly, it concerns the use of said compounds as antioxidant agents, in particular for preparing medicines designed to increase the intracellular and/or extracellular level of glutathione (GSH).

  本发明涉及通式（I）化合物（其中R和R'代表烷基或芳基基团，R"是氢或CO-R1基团，其中R1是烷基或芳基基团；以及由通式（I）化合物的两个硫原子中的一个或另一个形成的二硫键所形成的二聚体；以及相应的噻唑烷形式），其制备方法和用途。更具体地，涉及使用所述化合物作为抗氧化剂，特别是用于制备旨在增加谷胱甘肽（GSH）细胞内和/或细胞外水平的药物。
