Biological ligands
The interaction of ligands with their binding sites can be characterized in terms of a binding affinity. In general, high-affinity ligand binding results from greater attractive forces between the ligand and its receptor while low-affinity ligand binding involves less attractive force. In general, high-affinity binding results in a higher occupancy of the receptor by its ligand than is the case for low-affinity … WebFeb 1, 2024 · The most common approach for the prediction of biological activity based on ligands is the quantitative structure–activity relationship (QSAR) proposed by Hansch et al., which is based on the principle that ligand activity is correlated with molecular structure and the activity value can be predicted by establishing a mathematical model based on the …
