Background:

JNJ-46778212 (VU 0409551) is an mGlu5 positive allosteric modulator with an EC50 of 260 nM.

In oral brain/plasma studies, JNJ-46778212 displays excellent CNS penetration[1]. JNJ-46778212 enhances NMDAR function and rescues long-term potentiation in hippocampal slices obtained from SR?/? mice. The administration of JNJ-46778212 to SR?/? mice reverses their deficits in several neuroplasticity signaling pathways and improves their contextual fear memory[2].
