WebA drug’s action is affected by the quantity of drug that reaches the receptor and the degree of attraction (affinity) between it and its receptor on the cell’s surface. Once bound to their receptor, drugs vary in their ability to produce an effect (intrinsic activity).

More specifically the Ki is reflective of the binding affinity and the IC50 is more reflective of the functional strength of the inhibitor ... WebBinding affinity is the strength of the binding interaction between a single biomolecule (e.g. protein or DNA) to its ligand/binding partner (e.g. drug or inhibitor). Binding affinity is typically measured and reported by the equilibrium dissociation constant (K D ), which is used to evaluate and rank order strengths of bimolecular interactions. does ty lee have sisters WebJun 23, 2024 · One commonly used measure of the affinity (strength) with which a drug binds to a particular type (or subtype) of receptor is its Ki or inhibitory constant (also … WebDec 1, 2004 · Agonists and ED 50.
