Abstract
Objective: Antimicrobials and
antifungals are the most acquired drugs in the world. Today, it becomes
necessary to create new drugs with antimicrobial and antifungal effect. The purpose of our research is the synthesis of new series
of 5-(1Н-tetrazole-1-yl)-4H-1,2,4-triazole-3-amine, the establishment of
physical-chemical, antimicrobial and antifungal properties for all synthesized
compounds.
Materials and
Methods: 5-(1Н-tetrazole-1-yl-methyl)-4H-1,2,4-triazole-3-yl-1-(alkyl-,
aryl-)-methanimines were synthesized by reacting of 5-(1H-tetrazole-1-yl-methyl)-4H-1,2,4-triazole-3-amine
with aldehydes in acetic acid. Then, sodium borohydride was selected as a
reducing agent, which allowed for the restoration of the double bond. The
structures of synthesized compounds were confirmed by IR, 1H NMR and
mass spectra. The synthesized compounds were evaluated for antimicrobial and antifungal activity
by "serial dilutions" method.
Result and Discussion: During the synthetic studies the new
series of 22 compounds were obtained. The
5-(1Н-tetrazole-1-yl-methyl)-4H-1,2,4-triazole-3-yl-1-(5-nitrofuran-2-yl)methanimine
was observed to be most possessing good antimicrobial and antifungal and has
exceeded the reference standard for Staphylococcus aureus (12,5/25 mg/ml),
Escherichia coli (50/100 mg/ml), Pseudomonas Aeruginosa (100/200 mg/ml), Candida
albicans (50/50 mg/ml).
