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.
本文披露了一种新型的取代-1H-喹唑啉-2,4-二酮衍生物,其制备方法以及含有该衍生物的药物组合物。这种新型的取代-1H-喹唑啉-2,4-二酮衍生物在与其他受体相比对5-HT6受体的结合亲和力和选择性方面表现出色,抑制5-羟色胺(5-HT)刺激的cAMP积累,并破坏大鼠中阿波莫啡(2 mg/kg,i.p.)诱导的过度活动。由于这些效果,这些衍生物在治疗与5-HT6受体相关的中枢神经系统疾病中非常有用。
