ligand-based drug design

https://doi.org/10.1351/goldbook.12679
Method of drug discovery and/or optimization in which the pursuit of new structures and/or structural modifications is based upon one or more ligands known to interact with the molecular target of interest.
Note: This approach is applicable even when no structural detail of the target is known. In such cases a series of analogues is usually prepared and tested to produce structure-activity relationship data that can be extrapolated to indirectly derive a topographical map of the biological surface.
