Synthesis of some new 5-(1-phenyl-1H-1,2,3-triazol-4-yl)-1H-tetrazoles and evaluation of their antimicrobial activity
摘要:
a series of new tetrazole derivatives were synthesized by a reaction of triazole oxime with sodium azide catalyzed by copper acetate and isolated with high yield under mild conditions. All synthesized compounds were characterized by IR, NMR, and MS data. Evaluation of antimicrobial activity of the products against Gram-positive and Gram-negative bacterial and antifungal strains has been carried out. Among the compounds 3a, 3c, 3e, and 3f exhibited high antibacterial activity and compounds 3a, 3c, 3e demonstrated high antifungal activity.
A series of novel bis‐heterocycles encompassing isoxazolines and triazoles were synthesized through a novel one‐pot procedure that involves in situ generation of nitrile oxide and its 1,3‐dipolar cycloaddition to variedly substituted acrylates. The synthesized bis‐heterocycles (8a–l) were subjected to in vitro lymphocyte proliferation assays followed by in vivo studies of the more active compounds
通过一种新型的单锅法合成了一系列包含异恶唑啉和三唑的新型双杂环,该法涉及原位生成氧化腈及其对不同取代的丙烯酸酯的 1,3-偶极环加成反应。合成的双杂环化合物(8a-l)进行体外淋巴细胞增殖试验,然后对活性更高的化合物(8g 和 8h)进行体内研究,以评估它们对免疫系统各个方面的影响,如离体脾细胞增殖。 T 细胞和 B 细胞增殖)、抗体产生(HA 滴度)、迟发型超敏反应、T 细胞亚型(CD4 和 CD8)、细胞因子产生(IL-2、IFN-γ 和 IL-4)、NO (巨噬细胞)产生和毒性作用。
