L-glutamat je jedan od glavnih ekscitatornih neurotransmitera centralnog nervnog sistema. On aktivira jonotropne i metabotropne glutamatne receptore. Glutamatergična neurotransmisija učestvuje u većini aspekata normalne moždane funkcije. Ona može da bude modifikovana mnogim neuropatološkim uslovima. Metabotropini glutamatni receptori su familija G protein spregnutih receptora, koji se dele u tri grupe na bazi homologije sekvenci, mehanizama prenosa signala, i farmakoloških svojstava. Grupa I obuhvata GRM1 i GRM5. Za njih je pokazano da aktiviraju fosfolipazu C. Grupa II obuhvata GRM2 i GRM3, dok su grupi III GRM4, GRM6, GRM7 i GRM8. Grupe II i III receptora su povezane sa inhibicijom kaskade cikličnog AMP-a, ali se razlikuju u selektivnost na agoniste.[2]

Ligandi уреди

Potpuno mGluR3 selektivni agensi nisu dostupni. Poznati su mešoviti mGluR2/3 (grupa II) ligandi sa selektivnošću u odnosu na druge mGluR podtipove. Neki od njih imaju nisku oralnu biodostupnost, ali postoji mogućnost njihove upotrebe u obliku proleka.[3]
