Abstract:The bis-1,3,4-oxadiazole-thione and bis-4-amino-1,2,4-triazole-thiol derivatives from L-tartaric acid were synthesized. The synthetic intermediates, ester, hydrazide and oxadiazole derivatives have shown a significant tendency to form complexes with Fe(III), Ni(II) and Cu(II) ions. The formation of complexes with metals was detected by UV-Vis and IR spectroscopy. A novel complex nucleoside from bis-4-amino-1,2,4-triazole-thiol derivative with l-arabinose was also synthesized. The antimicrobial activity for final and synthetic intermediates in vitro against the microorganisms: Escherichia coli, Pseudomonas aeruginosa, Yersinia pseudotuberculosis, Enterococcus faecalis, Staphylococcus aureus and Candida albicans were examined and some products showed noticeable activity against the tested microorganisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
