VU6001966 is a brain-penetrant and selective mGlu2 receptor inhibitor. VU6001966 blocks mGlu2 receptor activity, counteracts LY379268 (HY-103558)-mediated blood-brain barrier protection and inflammatory cytokine dampening in microglia under inflammatory conditions. VU6001966 enhances antidepressant effects when combined with Scopolamine (HY-N0296). VU6001966 can be used for the research of major depressive disorder[1][2][3][4].
