An improved procedure for the synthesis of 3-amino-9-arylsubstituted-thieno[3,2-b]benzothiazine S,S-dioxide 2-decarboxylated is reported. Thieno-[3,2-b]benzothiazine S,S-dioxide derivatives were investigated for their abilities to inhibit beta-hematin formation, hemoglobin hydrolysis and in vivo for their efficacy in rodent Plasmodium berghei. Compounds 5j-o were the most promising as inhibitors of
报道了一种改进的合成3-氨基-9-芳基取代的噻吩并[3,2-b]苯并噻嗪S,S-二氧化物2-脱羧的方法。研究了噻吩并[[3,2-b]苯并噻嗪S,S-二氧化物衍生物具有抑制β-血红素形成,血红蛋白水解的能力,并具有体内杀灭鼠伯氏疟原虫的功效。化合物5j-o是最有希望的血红蛋白水解抑制剂,但是,这些化合物不如氯喹有效。在该系列中进行了结构-活性关系(SAR)研究。我们的结果使我们能够确定产生生物学反应的最小结构要求。
