Methoctramine (hydrate)

Methoctramine is a potent and selective M2 muscarinic acetylcholine receptor antagonist, exhibiting high affinity for M2 (IC50 = 6.1 nM) over other muscarinic receptor subtypes. It is a valuable research tool for investigating cholinergic signaling in cardiovascular, neurological, and pulmonary systems, applicable in both in vitro binding assays and in vivo functional studies.
