AZD-8529 is a potent, highly selective and orally bioavailable positive allosteric modulator of mGluR2, with an EC50 of 285 nM, and shows no positive allosteric modulator responses at 20-25 M on the mGluR1, 3, 4, 5, 6, 7, and 8 subtypes.

AZD8529 is a selective metabotropic glutamate receptor 2 (mGluR2) positive allosteric modulator (PAM) th at potentiates DCG-IV-induced GTPγS binding to membrane from human mGluR2but not mGluR1/3/4/5/6/7/8CaR/Gqi5 fusion-expressing HEK293 cells (EC50/Emax = 285 nM/59.9%) with no mGluR agonist/antagonist activity and little or no affinity toward a panel of 50 other receptors. AZD8529 is shown to reduce nicotine self-administration and cue-induced reinstatement of nicotine-seeking responses in squirrel monkeys (0.3-10 mg/kg i.m.) and rats (1.75-58.3 mg/kg) as well as cue-induced methamphetamine seeking in rats (20 and 40 mg/kg s.c.) in vivo.
