AC260584 is an M1 muscarinic receptor allosteric agonist with a pEC50 of 7.6.

IC50 & Target

pEC50: 7.6 (M1)[1]

In Vitro

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].

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

In Vivo

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].

Purity & Documentation
Animal Administration

Rats: AC260584 is formulated in 100% 50 mM sodium acetate buffer pH 4.5 at a concentration of 1 mg/mL. Dosing solution is at room temperature prior to dosing. Three rats are administered AC260584 (2 mg/kg) intravenously and three rats are administered the drug orally (10 mg/kg). Rats dosed intravenously are catheterized at the jugular and femoral vein, while those dosed orally are catheterized only at the femoral vein. Rats are housed individually, fasted overnight and dosed by individual body weight. Plasma samples are collected at several time points and analyzed by LC/MS/MS[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
