    Product Description

    Quipazine is an agonist of the serotonin (5-HT) receptor subtypes 5-HT2A, 5-HT2B, and 5-HT2C.1 It induces calcium accumulation in CHO-K1 cells expressing 5-HT2A, 5-HT2B, or 5-HT2C (EC50s = 309.03, 177.83, and 338.84 nM, respectively, for the human receptors). Quipazine also binds to the 5-HT3 receptor (Ki = 2.1 nM).2 It decreases food intake in rats when administered at doses of 2.5, 5, or 10 mg/kg.3 Quipazine (0.3 mg/kg per day), in combination with 8-hydroxy DPAT (Item No. 22608), electrode stimulation of dorsal and lumbar spine regions, and locomotor training, restores spinal circuitry function, improves gait regularity, and increases interlimb coordination and limb weight-bearing in a rat model of hindlimb paralysis induced by spinal cord transection.4

    WARNING This product is not for human or veterinary use.
