Disclosed are alicyclic[c]benzopyrone derivatives and use thereof. The alicyclic[c]benzopyrone derivatives are compounds represented by formula I or their salts. The present compounds not only significantly improve high activity induced by MK-801, but also effectively improve clambering symptom induced by Apomorphine and do not cause EPS within effective dose. These in vitro targets and in vivo pharmacological models are closely related to diseases of the nervous system caused by dopamine dysfunction, especially schizophrenia. Therefore the present compounds can be used for the treatment of central nervous system diseases, especially schizophrenia. ED

本发明涉及螺环[c]苯并吡喃衍生物及其用途。螺环[c]苯并吡喃衍生物是由式I所表示的化合物或其盐。本化合物不仅显著改善了MK-801引起的高活性,而且有效地改善了阿泼吗啉引起的攀爬症状,并且在有效剂量范围内不会引起EPS。这些体外靶点和体内药理模型与因多巴胺功能障碍引起的神经系统疾病密切相关,特别是精神分裂症。因此,本化合物可用于治疗中枢神经系统疾病,特别是精神分裂症。在两种动物模型即MK-801引起的高活性和阿泼吗啉引起的攀爬症状中,ED50更低,效果更强,而在病理模型的动物模型中,ED50更高,治疗指数更大。
