| Bioactivity | W-84 (dibromide) is a potent allosteric modulator of M2-cholinoceptors, which retards [3H]N-methylscopolamine dissociation. W-84 dibromide can stabilize cholinergic antagonist-receptor complexes. W-84 (dibromide) is a non-competitive muscarinic acetylcholine receptors antagonist with allosteric effects. W-84 (dibromide) protects over additively against an organophosphate-intoxication when applied in combination with atropine[1][2][3]. |
| Target | muscarinic acetylcholine receptors |
| Invitro | The stabilizing effect of W-84 (dibromide) on antagonist-receptor complexes may explain the overadditive protective action exerted by the combination of atropine and W-84 (dibromide) against organophosphate intoxication[1]. W-84 (dibromide) not only inhibits radioligand association but also strongly stabilizes antagonist-receptor complexes[2]. |
