New series of hydrazones 5–18 were synthesized, in good yields, by reacting 4-methyl-2-(4-(trifluoromethyl)phenyl)thiazole-5-carbohydrazide with differently substituted benzaldehyde. The resulting compounds were characterized via elemental analysis, physico-chemical and spectral data. An antimicrobial screening was done, using Gram (+), Gram (−) bacteria and one fungal strain. Tested molecules displayed moderate-to-good growth inhibition activity. 2,2-Diphenyl-1-picrylhydrazide assay was used to test the antioxidant properties of the compounds. Monohydroxy (14–16), para-fluorine (13) and 2,4-dichlorine (17) derivatives exhibited better free-radical scavenging ability than the other investigated molecules.
新系列的肼醇(5-18)通过将4-甲基-2-(4-(三氟甲基)苯)噻唑-5-羟肼与不同取代的苯甲醛反应合成,得到良好收率。所得到的化合物通过元素分析、物理化学和光谱数据进行了表征。进行了抗微生物筛选,使用了革兰氏阳性、革兰氏阴性细菌和一种真菌菌株。测试的分子显示出中等到良好的抑制生长活性。使用2,2-二苯-1-苦味肼测定法测试了化合物的抗氧化特性。单羟基(14-16)、对氟(13)和2,4-二氯(17)衍生物表现出比其他调查分子更好的自由基清除能力。
