Abstract The synthesis and characterization of 18 novel thiosemicarbazones have been investigated as part of a research program on development of compounds with antibacterial and antioxidant activities. Among the tested compounds, 2-(4-hydroxybenzylidene)-N-[4-(trifluoromethoxy)phenyl]hydrazine carbothioamide (3g) and 2-(thiophen-2-ylmethylidene)-N-[4-(morpholin-4-yl)phenyl]hydrazine carbothioamide
摘要 作为开发具有抗菌和抗氧化活性的化合物的研究计划的一部分,对 18 种新型缩氨基硫脲的合成和表征进行了研究。在测试的化合物中,2-(4-羟基苯亚甲基)-N-[4-(三氟甲氧基)苯基]肼硫代酰胺(3g)和2-(噻吩-2-基亚甲基)-N-[4-(吗啉-4-基) )苯基]肼硫代酰胺 (4b) 在低浓度 (0.5 μg/mL) 下对革兰氏阳性病原体(粪肠球菌和金黄色葡萄球菌)显示出优异的抑制效力。还发现所有测试的化合物对 2,2-二苯基-1-苦基肼 (DPPH) 自由基和 2,2'-偶氮基双(3-乙基苯并噻唑啉-6-磺酸) (ABTS) 自由基阳离子具有抗氧化活性。[本文提供补充材料。去出版商'
