Lu AF21934

Research use only, not for human use.

Lu AF21934 is a brain-penetrant and selective mGlu4 receptor positive allosteric modulator (IC50: 500 nM, human).

Lu AF21934 is a positive allosteric modulator of mGlu4 receptors. Lu AF21934 reduces the harmaline-induced hyperactivity but not tremor in rats. The actions of Lu AF21934 are 5-HT1A receptor-dependent. Activation of the mGlu4 receptor may be a promising mechanism for the development of novel antipsychotic drugs, efficacious toward positive, negative, and cognitive symptoms.

Lu AF21934 treatment shows a dose-dependent anxiolytic-like effect in the stress-induced hyperthermia, four-plate, and marble-burying tests. The anti-hyperthermic effect of Lu AF21934 (5 mg/kg) in the SIH test is inhibited by the benzodiazepine receptor antagonist flumazenil (10 mg/kg) and is not serotonin dependent. Lu AF21934 does not produce antidepressant-like effects in the tail suspension test in mice; however, it decreases the basal locomotor activity of mice that are not habituated to activity cages. Lu AF21934 (0.5-5 mg/kg sc) does not influence tremor but at doses of 0.5 and 2.5 mg/kg reverses harmaline-induced hyperactivity. Lu AF21934 at a dose of 2.5 mg/kg potentiates the inhibitory influence of harmaline on the exploratory activity and AP1 during the first 30 min of the measurement and counteracts the harmaline-increased basic activity during the period of 30-90 min. Lu AF21934 (0.1-5 mg/kg) dose-dependently inhibits hyperactivity induced by MK-801 or amphetamine. It also antagonizes head twitches and increases frequency of spontaneous excitatory postsynaptic currents in brain slices, induced by DOI.
