Disclosed herein are novel substituted-1H-quinazoline-2,4-dione derivatives, a preparation method thereof, and a pharmaceutical composition containing the same. The novel substituted-1H-quinazoline-2,4-dione derivatives are excellent in binding affinity and selectivity for 5-HT6 receptors over other receptors, inhibit serotonin(5-HT)-stimulated cAMP accumulation, and disrupt apomorphine(2 mg/kg, i.p.)-induced hyperactivity in rats. Thanks to these effects, the derivatives are useful in the treatment of 5-HT6 receptor-related central nervous system diseases.
