1.Peripheral administration of group III mGlu receptor agonist ACPT-I exerts potential antipsychotic effects in rodents.

Several lines of evidence implicate dysfunction of glutamatergic neurotransmission in the pathophysiology of schizophrenia. Previous behavioral studies have indicated that metabotropic glutamate (mGlu) receptors may be useful targets for the treatment of psychosis. It has been shown that agonists and positive allosteric modulators of group II mGlu receptors produce potential antipsychotic effects in behavioral models of schizophrenia in rodents. Group III mGlu receptors seem to be also promising targets for a variety of neuropsychiatric and neurodegenerative disorders. However, despite encouraging data in animal models, most ligands of group III mGlu receptors still suffer from weak affinities, incapacity to cross the blood-brain barrier or absence of full pharmacological characterization. These limitations slow down the validation process of group III mGlu receptors as therapeutic targets. In this work, we choose to study an agonist of group III mGlu receptors (1S,3R,4S)-1-aminocyclo-pentane-1,3,4-tricarboxylic acid (ACPT-I) using intraperitoneal administration in three animal behavioral models predictive of psychosis or hallucinations. The results of the present study show that ACPT-I, given at doses of 10 or 30mg/kg, decreased MK-801-induced hyperlocomotion and at a dose of 100mg/kg decreased amphetamine-induced hyperlocomotion in rats.
2.The group III mGlu receptor agonist ACPT-I exerts anxiolytic-like but not antidepressant-like effects, mediated by the serotonergic and GABA-ergic systems.

Our earlier studies have demonstrated that (1S,3R,4S)-1-aminocyclo-pentane-1,3,4-tricarboxylic acid ACPT-I, a group III mGlu receptor agonist, produced anxiolytic-like and antidepressant-like actions after central administration. Here we describe the anxiolytic-like effects of ACPT-I after intraperitoneal administration in the stress-induced hyperthermia (SIH), elevated plus-maze (PMT) tests in mice and in the Vogel test in rats. However, the compound did not produce antidepressant-like effects in the tail suspension test (TST) or in the forced swim test (FST) in mice. The potential anxiolytic effect of ACPT-I (20 mg/kg) in the SIH test was inhibited by the benzodiazepine receptor antagonist flumazenil (given i.p., 10 mg/kg), and by a 5-HT(1A) receptor antagonist N-{2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl}-N-(2-pyridynyl) cyclohexane-carboxamide (WAY100635) (0.1 mg/kg s.c.). At the same time, ritanserin (0.5 mg/kg i.p.), the 5-HT2A/C receptor antagonist, did not change the anxiolytic-like effects of ACPT-I. The results of these studies indicate that the GABA-ergic and serotonergic systems are involved in the potential anxiolytic action of ACPT-I.
3.Functional interaction between adenosine A2A and group III metabotropic glutamate receptors to reduce parkinsonian symptoms in rats.
Lopez S;Turle-Lorenzo N;Johnston TH;Brotchie JM;Schann S;Neuville P;Amalric M Neuropharmacology. 2008 Sep;55(4):483-90. doi: 10.1016/j.neuropharm.2008.06.038. Epub 2008 Jun 27.
Non-dopaminergic drugs acting either on adenosine A2A or metabotropic glutamate (mGlu) receptors reduce motor impairment in animal models of Parkinson's disease (PD), suggesting a possible functional interaction between these receptors to regulate basal ganglia function. The present study therefore tested the behavioural effects of compounds acting selectively on A2A or on specific mGlu receptor subtypes, alone or in combination, in rodent models of PD. Acute administration of the adenosine A2A receptor antagonists CSC or MSX-3 at the highest doses tested (5 and 1.25mg/kg, respectively) significantly reduces haloperidol-induced catalepsy. Furthermore, the anticataleptic effect of MSX-3 was enhanced by a 3-week treatment. Acute administration of the selective group III mGlu agonist ACPT-I produces potent anticataleptic effects and prolongs time on rotarod of 6-OHDA-lesioned rats. In contrast, acute or chronic administration of MPEP (mGlu5 receptor antagonist) has no anticataleptic action. Furthermore, the acute co-administration of ACPT-I 1mg/kg, but not 5mg/kg, with CSC markedly reduces catalepsy. Opposite effects are observed after a 3-week co-administration. The co-administration of ACPT-I with MSX-3 has anticataleptic effects both after acute or chronic treatment.
