LSN2814617 is a positive allosteric modulator of metabotropic glutamate receptor 5 (mGluR5).¹It potentiates glutamate-induced calcium mobilization in MCB3901 cells expressing human mGluR5 (EC₅₀= 52 nM). LSN2814617 increases rat hippocampal mGluR5 receptor occupancy (ED₅₀= 13 mg/kg). It increases wakefulness and decreases non-rapid eye movement (NREM) and REM sleep in rats when administered at doses of 0.3, 1, and 3 mg/kg.
