Abstract

The study deals with the synthesis and evaluation of some novel triazoles. Amine linked triazoles were prepared through multistep syntheses. 4-Iodobenzoic acid was taken as initial reactant material, which was converted into methyl ester, then to hydrazide and finally into triazole via dithiocarbazate salt. The triazole was treated with chloroacetyl chloride and further with secondary amines to get the title compounds. Structures of the synthesized compounds were elucidated by Fourier transform infrared spectroscopy (FTIR), 13C and 1H nuclear magnetic resonance (NMR), mass spectrometry and elemental analysis. The synthesized compounds were screened for their antimicrobial activity. The study was carried out against four bacteria and three fungi by disc diffusion method using ciprofloxacin and fluconazole as reference drug for antibacterial and antifungal activities respectively. All the synthesized compounds exhibited zones of inhibition against Candida albicans, Aspergillus niger and Fusarium oxysporum, but the inhibition was more prominent as shown by compound T83. Similarly antibacterial activity was studied against Staphylococcus aureus, Basillus subtilis, Psedomonas aeruginosa and Escherichia coli. Data revealed that compounds T81 and T83 were effective against the bacterial strains. Minimum inhibitory concentration test (MIC) was also carried out to ascertain the bacteriostatic property of the test compounds.
