Foliglurax monohydrochloride (PXT002331 monohydrochloride) is a highly selective and potent, brain-penetrant mGluR4 positive allosteric modulator (PAM), with an EC50 of 79±19 nM[1]. Antiparkinsonian effect[1].
Foliglurax, a highly selective and potent mGlu4 receptor PAM with a marked brain-penetrance feature, might revolutionize the field of mGlu4 receptor drug targeting in CNS disorders[2].
