设计合成了3类C(3)-1,2,4-三氮唑取代的1,5-苯并硫氮杂(艹卓)化合物,2,3-二氢/2,5-二氢/2,3,4,5-四氢-3-(1,2,4-三氮唑)-4-芳基-1,5-苯并硫氮杂(艹卓).研究了中间体及目标产物的合成条件,确定了其中2个副产物的结构.目标产物的抑菌活性测试表明,2,3-二氢/2,5-二氢-3-(1,2,4-三氮唑)-4-芳基-1,5-苯并硫氮杂(艹卓)对新生隐球菌和白色念珠菌表现出很高的抑制作用,在200 μg/disc的浓度下,有4个化合物对新生隐球菌的抑制作用高于对照药物氟康唑,有3个化合物对白色念珠菌的抑制活性高于对照药物氟康唑.初步抑真菌构效关系研究表明,1,2,4-三氮唑环和C=N双键是2,3-二氢-3-(1,2,4-三氮唑)-4-芳基-1,5-苯并硫氮杂(艹卓)抑真菌活性的关键药效团.

Three kinds of C(3)-1,2,4-triazolyl-1,5-benzothiazepines, 2,3-dihydro/2,5-dihydro/2,3,4,5-tetrahydro-3-(1,2,4-tria-zolyl)-4-aryl-1,5-benzothiazepines, were designed and synthesized. The synthesis conditions of intermediates and target products were studied, and the structures of two by-products were determined. The antimicrobial activity test of the target products showed that 2,3-dihydro/2,5-dihydro-3-(1,2,4-triazolyl)-4-aryl-1,5-benzothiazepines exhibited high inhibitory effects on C. neoformans and C. albicans. At concentration of 200 μg/disc, the inhibitory effects of four compounds on C. neoformans were stronger than that of fluconazol, and the inhibitory effects of three compounds on C. albicans were stronger than that of fluconazol. The preliminary study on the structure-activity relationship of antifungal revealed that 1,2,4-triazolyl and C=N double bond were the key function groups in the antifungal activity of 2,3-dihydro-3-(1,2,4-triazolyl)-4-aryl-1,5-benzothiazepines.

Key words: 1,5-benzothiazepine, 1,2,4-triazole, antimicrobical activity, structure-activity relationship
