We describe here the discovery and the structure-activity relationship (SAR) of a series of 4-(1-Aryltriazol-4-yl)-tetrahydropyridines as novel mGluR1 antagonists. Our extensive chemical modification of lead compound 2 successfully led to fluoropyridine analogs 7j and 1 with improved in vivo antagonistic activities. Among the evaluated compounds, chemically stable urea analog 1 showed oral antagonistic activity at dose ranges of 10-30mg/kg in an animal model.
