WebTherefore, if the agonist has a positive value and the inverse agonist has a negative value, the antagonist for the receptor takes both the agonist and inverse agonist back to a neutral state. One particular example is Ro15-4513 which is the inverse agonist of the benzodiazepine class of drugs (such as Xanax and Valium). Ro15-4513 and the ... WebInverse agonists stabilize the receptor in its inactive conformation and act similarly to competitive antagonists. Many hormones, neurotransmitters (eg, acetylcholine, histamine, norepinephrine ), and drugs (eg, morphine, phenylephrine, isoproterenol, benzodiazepines, barbiturates) act as agonists. Antagonists prevent receptor activation. free background for a headshotWebInverse agonists exert the opposite effect of agonists. They bind to the ligand binding site of constitutively activated receptors and stabilize them in an inactive state, effectively exhibiting negative intrinsic activity (Fig. 4 ).
