4-methylenedioxyphenyl, and 2,3,5-trichlorophenyl moiety showed excellent antiinflammatory activity. The antimicrobial screening studies revealed that compounds with 4-anisyl, 4-methylthiophenyl, 3,4-methylenedioxyphenyl, and 2,3,5-trichlorophenyl at position 5 of the arylidenetriazolothiazolidinone moiety showed excellent activity against all tested strains at 6.25 μg cm−3 concentrations.
通过3-(2,4-二氯-5-氟苯基)-4 H -1,2,4-三唑-5-硫醇的一锅反应获得了一系列的2,4-二氯-5-氟苯基取代的芳基三唑并恶唑烷酮。 在乙酸酐,乙酸和乙酸钠存在下用取代的苯甲醛和一氯乙酸制得 新合成的化合物的结构经IR,1表征和确认1 H NMR,质谱和元素分析。带有4-甲基硫代苯基,3,4-亚甲基二氧苯基和2,3,5-三氯苯基部分的化合物显示出优异的抗炎活性。抗菌筛选研究表明,在芳基内氮杂唑并噻唑烷酮部分的5位上带有4-茴香基,4-甲硫基苯基,3,4-亚甲基二氧苯基和2,3,5-三氯苯基的化合物在6.25μgcm -3的条件下显示出对所有测试菌株的优异活性浓度。
