Abstract

Objective: To design, synthesize and in vitro antitubercular, antifungal and antioxidant evaluation of some novel mercapto 1, 2, 4–triazole derivatives.

Methods: New derivatives were designed by using various software like ACD Lab chemsketch, molinspiration and autodock. Designed molecules are obeying Lipinski’s rule of five and having highest binding score was selected for the synthesis. The synthesized compounds were subjected to TLC, melting point determination, FTIR, 1H NMR, 13C NMR and mass spectral analysis. The newly synthesized compounds were investigated for in vitro antitubercular evaluation by MABA method, antifungal evaluation by cup plate method and antioxidant evaluation by DPPH scavenging assay.

Results: A virtual screening was carried out through docking designed compounds into the InhA and CYP-51 binding site to predict if these compounds have an analogous binding mode of the enoyl ACP reductase (InhA) and CYP-51 inhibitors. Three derivatives (4a1, 4a2 and 4a3) were selected for the synthesis with the help of in silico modeling. The selected derivatives were synthesized by a conventional method. All the synthesized compounds showed a characteristic peak in FT IR, 1H and 13C NMR and mass spectroscopic studies. All the selected derivatives showed antitubercular, antifungal and antioxidant activity.

Conclusion: The derivatives were synthesized adopting simple and laboratory friendly reaction conditions to give the target compounds in quantitative yields. Newer derivatives possess good antitubercular, antifungal and antioxidant activity.
