reducing agents. The performed TGA, and c-DTA measurements showed different thermal stable of thiosemicarbazone derivatives. The T2 derivative was the most thermally resistant. On the other hand, the T11 derivative was the least resistant. The performed thermal analysis showed that most of the derivatives underwent two-stage thermal decomposition (13 samples).
本研究的目的是评估缩氨基硫脲衍生物的抗菌、抗结核和抗氧化活性。测定了 19 种化合物的热稳定性和热降解性。体外试验获得的结果表明所选化合物具有抗金黄色葡萄球菌、表皮葡萄球菌和结核分枝杆菌的潜力。一些化合物被证明是活性自由基清除剂,同时 Fe 3+还原剂。进行的 TGA 和 c-DTA 测量显示缩氨基硫脲衍生物的不同热稳定性。T2 衍生物是最耐热的。另一方面,T11 衍生物的抵抗力最低。进行的热分析表明,大多数衍生物经历了两阶段热分解(13 个样品)。
