摘要

Tuberculosis (TB) is an infectious disease and caused by various strains of mycobacteria. In the present study, pharmacophore model was developed using single ligand by ligand-based drug discovery approach. The key features responsible for DprE1 inhibitory activity were taken into consideration for developing pharmacophore. After the virtual screening, top 1000 hits were further subjected to docking study using GLIDE module, Schr?dinger. Docking studies have shown promising interaction with amino residues with better glide score. Ligand-based drug design approach yielded a series of 15, 2-(6-nitrobenzo[ d]thiazol-2-ylthio)-N-benzyl-N-(6-nitrobenzo[d]thiazol-2-yl)acetamide derivatives. All synthesized derivatives were characterized using NMR, mass, CHN analysis. The synthesized compounds were screened for In vitro antitubercular activity against Mycobacterium tuberculosis (H_(37)Rv). Four compounds, 5g (MIC-1.01 lM); 5i (MIC- 0.91 lM); 5k (MIC-0.82 lM); and 5o (MIC-1.04 lM) has shown promising activity compared to MIC of standard isoniazid (INH) and DprE1 enzyme inhibition was compared to BTZ043. Two halogen-substituted compounds have exhibited drastic enzyme inhibition.
