Description

Methoctramine tetrahydrochloride is a potent and cardioselectivity antagonist of M2 muscarinic receptor. Methoctramine tetrahydrochloride can inhibit Muscarine-induced bradycardia in vivo^[1]^[2]^[3].

IC₅₀ & Target

M2 muscarinic receptor^[1]

In Vitro

Methoctramine tetrahydrochloride attenuates Acetylcholine (ACh)- and Arecaidine propargyl ester (APE)-induced increases in PG synthesis in a concentration-dependent manner^[1].
Methoctramine (0.01-1 μM) tetrahydrochloride causes facilitation of contractions induced by both pre- and postganglionic nerve stimulation in the guinea-pig isolated, innervated tracheal tube preparation^[2].
Methoctramine (≥10 μM) tetrahydrochloride reduces responses to both nerve stimulation and exogenous ACh^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Methoctramine (300 µg/kg; i.v.) tetrahydrochloride strongly inhibits the Methacholine- and Muscarine-induced bradycardia in the anaesthetized rat, respectively^[3].
