3-Substituted-5-hydroxy(mercapto)alkylidene-rhodanine derivatives in which the 3-substituent is lower alkyl, cycloalkyl, alkenyl, phenyl, phenylalkyl, substituted phenyl or pyridylmethyl and having anti-arthritic activity are generally prepared from the appropriate 5-unsubstituted rhodanine by reaction with an orthoester followed by alkaline hydrolysis of the intermediate 5-alkoxyalkylidene rhodanine to give the 5-hydroxyalkylidene products or treatment of the intermediate rhodanine derivative with sodium sulfide to give the 5-mercaptoalkylidene products.
通常,具有抗关节炎活性的3-取代-5-羟基(巯基)烷基亚硫代嘧啶衍生物,其中3-取代基为较低的烷基、环烷基、烯基、苯基、苯基烷基、取代苯基或吡啶甲基,是通过将适当的5-未取代的嘧啶与正交酯反应,然后对中间体5-烷氧基烷基亚硫代嘧啶进行碱性水解以得到5-羟基烷基亚硫代嘧啶产物或者将中间体嘧啶衍生物与硫化钠处理以得到5-巯基烷基亚硫代嘧啶产物制备而成。
