AC260584 is an M1 muscarinic receptor allosteric agonist with a pEC50 of 7.6.
AC260584 is found to be a potent (pEC50=7.6-7.7) and efficacious (90-98% of carbachol) muscarinic M1 receptor agonist. AC260584 shows functional selectivity for the M1 receptor over the M2, M3, M4 and M5 muscarinic receptor subtypes. Its selectivity is found to be similar in native tissues expressing mAChRs to its profile in recombinant systems[1].
In rodents, AC260584 activates extracellular signal regulated kinase 1 and 2 (ERK1/2) phosphorylation in the hippocampus, prefrontal cortex and perirhinal cortex. The ERK1/2 activation is dependent upon muscarinic M1 receptor activation since it is not observed in M1 knockout mice. AC260584 also improves the cognitive performance of mice in the novel object recognition assay and its action is blocked by the muscarinic receptor antagonist pirenzepine. In addition, AC260584 is found to be orally bioavailable in rodents[1]. AC260584 at 3 and 10 mg/kg significantly increases dopamine release in the medial prefrontal cortex and hippocampus. However, only the high dose of AC260584, 10 mg/kg (s.c.), significantly increases acetylcholine release in these regions[2].
