  Analgesic and antimicrobial studies of some 2,4-dichloro-5-fluorophenyl containing arylidenetriazolothiadiazines

  摘要：

  2,4-Dichloro-5-fluorophenyl containing 7-arylidenetriazolothiadiazines were obtained by the reaction of 4-amino-3-(2,4-dichloro-5-fluorophenyl)-5-mercapto-1,2,4-triazole with 2,3-dibromo-1,3-diarylpropan-1-ones, and also by the reaction of 4-amino-3-(2,4-dichloro-5-fluorophenyl)-5-mercapto-1,2,4-triazole with alpha-bromopropenones in the presence of a base. The structure of the 7-arylidenetriazolothiadiazines was confirmed by an alternative synthesis. A plausible mechanism for the formation of 7-arylidenetriazolothiadiazines is proposed. All newly synthesized compounds were screened for their analgesic and antimicrobial activities. Compounds bearing 4-chlorophenyl or 3,4-methylenedioxyphenyl moieties at position 7 of the arylidenetriazolothiadiazines showed excellent analgesic activity. Arylidenetriazolothiadiazines carrying a phenyl, 4-chlorophenyl, 4-methylphenyl, 3,4-dimethoxyphenyl, and 2,4-dichlorophenyl moieties at position 7 showed excellent antibacterial and antifungal activities.

  obtained by the bromination of chalcones at room temperature. Treatment of chalcone dibromides (4) with aryloxy acid hydrazides (5) in the presence of triethylamine gave chloro-fluorine containing hydroxy pyrazolines (7) rather than the expected 1-aryloxy-3-aryl-5-aryl pyrazoles (6). The structures of the newly synthesized compounds were confirmed by IR, NMR, mass and elemental analysis. All the compounds

  通过Claisen-Schmidt缩合反应制备了一系列含氯氟查尔酮（3）。查尔酮二溴化物（4）是通过在室温下溴化查尔酮而得到的。在三乙胺存在下，用芳氧基酰肼（5）处理查尔酮二溴化物（4），得到含氯氟代的羟基吡唑啉（7），而不是预期的1-芳氧基-3-芳基-5-芳基吡唑（6）。通过IR，NMR，质量和元素分析证实了新合成的化合物的结构。测试所有化合物的抗菌和抗真菌活性。一些化合物显示出非常好的抗菌活性和抗真菌活性。
