CDPPB is a drug used in scientific research which acts as a positive allosteric modulator selective for the metabotropic glutamate receptor subtype mGluR5.[1][2][3] It has antipsychotic effects in animal models,[4] and mGluR5 modulators are under investigation as potential drugs for the treatment of schizophrenia,[5] as well as other applications.[6][7]
