An expedient synthesis of novel triazoles, tetrazine and thiadiazoles, using conveniently accessible and commercially available starting materials has been achieved. The synthesized compounds were characterized by spectroscopic and elemental analyses, and screened for their antibacterial activities against four different strains, namely E. coli, P. aeruginosa, S. aureus and B. megaterium. In particular, the compounds 5, 24 and 26h exhibited excellent antibacterial activities compared to the reference antibiotic. To get further insight about their behavior, these compounds were tested for their antioxidant activities via SOD-like activity, DPPH free radical scavenging activity, ABST and NO, which showed promising results. Furthermore, these compounds effectively promoted the cleavage of genomic DNA as well, in the absence of any external additives.
利用方便易得的市售起始材料,实现了新型三唑、四氮杂嗪和噻二唑的快速合成。通过光谱和元素分析对合成的化合物进行了表征,并筛选了它们对四种不同菌株(即大肠杆菌、铜绿假单胞菌、金黄色葡萄球菌和巨大芽孢杆菌)的抗菌活性。与参考抗生素相比,化合物 5、24 和 26h 尤其表现出卓越的抗菌活性。为了进一步了解这些化合物的行为,研究人员通过 SOD 样活性、DPPH 自由基清除活性、ABST 和 NO 测试了它们的抗氧化活性。此外,在没有任何外部添加剂的情况下,这些化合物还能有效促进基因组 DNA 的裂解。
