WebAllosteric Modulator: A drug that binds to a receptor at a site distinct from the active site. Induces a conformational change in the receptor, which alters the affinity of the receptor for the endogenous ligand. Positive allosteric modulators increase the affinity, whilst negative allosteric modulators decrease the affinity. Antagonist WebAllosteric modulators can produce some interesting and useful effects. For example, Figure 11.23 shows the effect of the modulator ifenprodil on responses to NMDA [9]. It can be seen that this potency of ifenprodil actually increases with increasing concentrations of NMDA, that is, the agonist increases the affinity of the antagonist. This can ...
