7-Mercapto(or alkyl- or aralkylthio)-1,2,4-benzothiadiazine-1,1-dioxide compounds are described. Products are prepared by reducing a 7-chlorosulfonyl substituent to the 7-mercapto and then, if desired, alkylating or aralkylating to provide 7-thio substituent. Alternatively, a 4-RS-orthanilamide can be cyclized by known procedures to provide a 3-unsubstituted or 3-substituted analog. Products are xanthine oxidase inhibitors.
本文描述了7-巯基(或烷基或芳基硫)-1,2,4-苯并噻二嗪-1,1-二氧化物化合物。通过将7-氯磺酰取代基还原为7-巯基,然后,如果需要,烷基化或芳基化以提供7-硫取代基来制备产品。另外,可以通过已知的程序将4-RS-邻氨基苯酰胺环化以提供3-未取代或3-取代的类似物。产品是黄嘌呤氧化酶抑制剂。
