VU0467485 (AZ13713945) is a potent, selective, and orally bioavailable muscarinic acetylcholine receptor 4 (M4) positive allosteric modulator (PAM). VU0467485 (AZ13713945) potentiates activity of ACh at M4 with EC50s of 26.6 nM and 78.8 nM at rat and human M4 receptors, respectively. VU0467485 (AZ13713945) shows selectivity for M4 over human and rat M1/2/3/5. VU0467485 (AZ13713945) displays moderate to high CNS penetration. VU0467485 (AZ13713945) has antipsychotic-like activity[1].
VU0467485 (1-10 mg/kg; p.o.) has antipsychotic-like activity in an amphetamine-induced hyperlocomotion (AHL) rat model[1].VU0467485 (3 mg/kg; p.o.) treatment displays that the Cmax, AUCo-inf and elimination t1/2 were 1.2 μM, 3.8 μM?h and 4.2 hours, respectively[1]. Animal Model: Sprague Dawley rats (amphetamine-induced hyperlocomotion rat model) [1]
