Iperoxo is a potent superagonist of muscarinic acetylcholine receptor (mAChR) that activates M1, M2 and M3 receptors with pEC50 of 9.87, 10.1 and 9.78. [3H]Iperoxo can be used for direct probing activation-related conformational transitions of muscarinic receptors[1][2]. Iperoxo is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups. | [Biochem/physiol Actions]
Iperoxo forms an important building block for the class of G protein-coupled receptors modulators. Iperoxo specifically binds to the orthosteric site of the muscarinic acetylcholine receptor. It has a higher efficacy than the endogenous agonist acetylcholine. | [in vivo]
Iperoxo (0.01 mg/kg, sc, single dose) exhibitis analgesic activity in rats with an ID50 of 1 μg/kg[4].
