options has become a priority. In the present study, the synthesis and leishmanicidal activity of a series of 5-(nitroheteroaryl-2-yl)-1,3,4-thiadiazole derivatives are described. All compounds appeared to be potent anti-leishmanial agents against both promastigote and amastigote forms of Leishmania major (L. major). Amongst the synthesized compounds, 2-([1,4'-bipiperidin]-1'-yl)-5-(5-nitrofuran-2-yl)-1,3
能够被可用的治疗选择所替代的新型抗人类杀菌剂的开发已成为当务之急。在本研究中,描述了一系列5-(硝基杂芳基-2-基)-1,3,4-噻二唑衍生物的合成和杀菌活性。所有化合物似乎都是针对利什曼原虫(L.major)的前鞭毛体和鞭毛体形式的有效抗利什曼肽剂。在合成的化合物中,2-([[1,4'-bipiperidin] -1'-yl)-5-(5-nitrofuran-2-yl)-1,3,4-thiadiazole(IIa)和1-(5 -(1-甲基-5-硝基-1H-咪唑-2-基)-1,3,4-噻二唑-2-基)-4-(哌啶-1-基)哌啶(IIc)最有效。在所有化合物存在下,感染指数均在统计学上下降。氧化还原相关因素的分析表明,L。的暴露。IIa和IIc的主要细胞导致活性氧(ROS)的增加。此外,两种化合物能够以剂量无关的方式增加被感染的巨噬细胞中的ROS和NO水平。此外,我们证明了这些化合物在前鞭毛
