Abstract: Enduring pandemic nature of tuberculosis urges to explore novel antimycobacterial agents with different mechanism of actions. Plant containing 1,4-naphthoquinone derivatives showed promising antitubercular activity with novel mode of action and their synthetic/semi-synthetic derivatives devoid of toxicity. Structural requirements of naphthalene-1,4-dione derivatives towards antitubercular activity and cytotoxicity were explored using a mathematical model in order to understand their physicochemical parameters. A quantitative structure activity relationship study furnished some important structural insights for antitubercular activity, i.e. average connectivity index, information content index of neighborhood symmetry, aromatic ratio, and path/walk 3 Randic shape index. Similarly it also provides drivers for the cytotoxicity of compounds. These drivers will be helpful in further development of safer and potent 1,4-naphthoquinone derivatives.

Keywords: naphthalene-1,4-diones - QSAR - antitubercular activity - cytotoxicity
