Even though many synthetic drugs are available in the market, to increase the therapeutic efficacy and reduce toxicity. Isoniazid is the primary drug used in the treatment of tuberculosis.</p><p id="idm46041443825696">Methods:The main objective of the study is to perform molecular docking studies and synthesize the derivatives of isonicotinamide along with the anti-tubercular activity. The isonicotinamide derivatives (a-j) are prepared using isoniazid, carbon disulphate, methyl cyanide, and benzaldehyde derivatives and characterized by TLC, IR, 1HNMR, and Mass spectroscopy. The enzyme decaprenylphosphoryl-D-ribose oxidase (DprE1) of M. tuberculosis had good binding capacity with all the ligands revealed in molecular docking studies. In-vitro studies indicated that all the ligands showed anti-tuberculosis with strain M. tuberculosis.</p><p id="idm46041443829664">Results:The analysis was based on the binding energy and minimum inhibitory concentration (MIC). The highest and lowest binding energy is -4.22 Kcal/mol (f) and -8.45 Kcal/mol (d), and the MIC for compound d was found to be 644.22 nM. Among all the ligands, compound 5d has the most cytotoxic effect and lower IC50 values and better bioavailability.</p><p id="idm46041443834720">Conclusion:This investigation helps in the development of better anti-tubercular therapy.</p></abstract><kwd-group xml:lang="en"><kwd>&amp;lt</kwd><kwd>i&amp;amp</kwd><kwd>gt</kwd><kwd>DprE1&amp;lt</kwd><kwd>/i&amp;amp</kwd><kwd>gt</kwd><kwd>Isonicotinamide</kwd><kwd>&amp;lt</kwd><kwd>i&amp;amp</kwd><kwd>gt</kwd><kwd>MIC&amp;amp</kwd><kwd>lt</kwd><kwd>/i&amp;amp</kwd><kwd>gt</kwd><kwd>Tuberculosis</kwd><kwd>TPSA</kwd><kwd>Cytotoxicity.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Crystal RG.
