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].
