VU-29 is a positive allosteric modulator of metabotropic glutamate 5 (mGlu5) receptor (EC50=9 nM and Ki=244 nM for rmGluR5). VU-29 is selective for mGluR5 relative to other mGluR subtypes (EC50: rmGluR1/rmGluR2=557 nM/1.5 μM; hmGluR4=154 nM)[1][2].

Target	rat mGluR5:9 nM (EC50) rat mGluR1:557 nM (EC50) rat mGluR2:1.5 μM (EC50) hmGluR4:154 nM (EC50) rat mGluR5:224 nM (Ki)
In Vivo	VU-29 (500 nM) potentiates DHPG induced increases in phosphoinositide (PI) hydrolysis in rat hippocampal slices. VU-29 potentiates threshold TBS-induced long term potentiation (LTP) in rat hippocampal CA1 region. VU-29 (1 µM) potentiates chemically induced mGluR-long term depression (LTD) in area CA1 of the rat hippocampus. VU-29 (1 µM) potentiates stimulus-induced NMDA receptor-independent LTD[1].
