WebA drug’s ability to affect a given receptor is related to the drug’s affinity (probability of the drug occupying a receptor at any given instant) and intrinsic efficacy (intrinsic activity—degree to which a ligand activates receptors and leads to cellular response). A drug’s affinity and activity are determined by its chemical structure. WebThe binding of both agonist and antagonist in α 2 adrenergic receptors involves more π-π or cation-π interactions and fewer hydrogen bonds (Figure 6a,b), comparing to βARs (Figure 3b). The expansion of π interaction network is mainly caused by F7.39, conserved in all α 1 ARs and α 2 ARs but is N7.39 in βARs.
