3-position led to a substantial increase in in vitro potency. In particular, 3-fluoro-5-(5-pyridin-2-yl-2H-tetrazol-2-yl)benzonitrile (7) is a highly potent and selective mGlu5 receptor antagonist with good rat pharmacokinetics, brain penetration, and in vivo receptor occupancy.
对3-(5-吡啶-2--2-基-2H-四唑-2-基)苄腈2的苯环的构效关系研究导致发现在3-位的小的非氢键供体取代基大大提高了体外效能。特别是3-氟-5-(5-吡啶-2-基-2H-四唑-2-基)苄腈(7)是一种高效且选择性的mGlu5受体拮抗剂,具有良好的大鼠药代动力学,脑渗透性和体内活性受体占用。
