In this chapter, a brief introduction to ligand-based methodologies employed for designing of drug has been described. Generally, ligand-based approach for drug designing (LB-CADD) technique is employed when biological target structure is not known and hence, this technique is considered as an ancillary approach for the drug designing. The theoretical basis of ligand-based approach involves quantitative structure–activity relationships (QSAR) and biomolecular docking studies. Like molecular descriptors, molecular fingerprint, similarity searches, similarity networks and off-target predictions. Finally, a brief description of the present work is given.
