Naphmethonium dibromide is a very potent allosteric modulator of muscarinic receptors, selective for M2-receptors. Retards the dissociation of the antagonist N-methylscopolamine and exhibits positive cooperativity, i.e. shows higher affinity for occupied receptors compared to free receptors. Naphmethonium dibromide′s affinity for the free receptor is about 100-fold higher than with W84. pKA =8.29, p(αKA)=8.66, pEC50,diss=8.36.
