N-(3,5-二甲基金刚烷-1-基)-N’-取代苯基脲类化合物及其 制备方法和用途
技术领域
本发明属于药物化学技术领域,具体涉及N-(3,5-二甲基金刚烷-1-基)-N'-取代苯基脲类化合物,以及为活性成分的药物组合物,它们的制备方法及其在治疗阿尔茨海默病中的应用。
背景技术
阿尔茨海默病(Alzheimer’s disease,AD)是一种进行性发展的致死性神经退行性疾病,临床表现为认知和记忆功能不断恶化,日常生活能力进行性减退,并有各种神经精神症状和行为障碍,导致患者不能独立生活。据不完全统计,到2025年,世界范围内人老年性痴呆的患病人口将达到220万。在我国,老年痴呆症多发生于65岁以上老人,约占4%~5%,75岁以上的约占10%,85岁以上约占20%。因此,抗阿尔茨海默病药物的研究与开发已成为人们关注的热点。
然而,由于阿尔茨海默病的发病机制复杂,到目前为止,阿尔茨海默病的发病病因和机制尚未完全阐明。对阿尔茨海默病已有的治疗药物主要为乙酰胆碱酯酶抑制剂如他克林,加兰他敏,多奈哌齐,石杉碱甲等,这些药物在一定程度上缓解了阿尔茨海默病的发病进程,并不能根治该病,同时这些药物也伴随着严重的肝毒性和胃肠反应等副作用。因此,寻找针对AD病因的新的有效治疗药物和方法,成为当今研究的热点。
本发明的N-(3,5-二甲基金刚烷-1-基)-N'-取代苯基脲类化合物,通过药理活性测试,期望得到更好抗阿尔茨海默病的药物。迄今为止,还没有关于N-(3,5-二甲基金刚烷-1-基)-N'-取代苯基脲类化合物治疗阿尔茨海默病的报道。本发明首次公开其治疗阿尔茨海默病以及它的制备方法和用途。

实施例42:N-(3,5-二甲基金刚烷-1-基)-N'-取代苯基脲化合物抗阿尔茨海默病活性测试
1)实验材料
实验动物:SPF级的SD雄性大鼠
试剂:喹啉酸,注射用青霉素钠,水合氯醛,碘伏,火棉胶,氯化钠注射液,羧甲基纤维素钠
仪器:动物脑立体定位仪,微量进样器,万分之一天平,Morris 水迷宫视频分析系统:Y迷宫、新物体辨别装置,-80℃低温冰箱。
2)实验原理
大鼠Y迷宫实验
用自发交替反应率来反映大鼠的空间工作记忆功能。
自发交替反应率(%)=正确交替反应次数/(进臂总次数-2)×100
大鼠新物体辨别实验
用新物体的1h优先指数和1h辨别系数反映大鼠的辨别记忆功能。
1h优先指数计算公式如下:
1h优先指数=tB/(tA1+tB) 公式(1)
1h辨别系数计算公式如下:
1h辨别系数=(tB-tA1)/(tA1+tB) 公式(2)
水迷宫实验
(1)定向航行实验:指标为逃避潜伏期。
(2)空间探索实验:第四象限游泳的时间、路程及穿台次数等指标。
3)实验结果
在Y迷宫实验中,各组大鼠进臂总次数未见显著性差异(见图 2~图3),提示Meynert基底核注射喹啉酸和药物处理未对大鼠大脑皮层兴奋性产生影响。自发交替反应率结果表明,与假手术组相比,模型组大鼠自发交替反应率显著降低,提示模型组大鼠工作记忆能力下降。与模型组相比,JCC-12以及JCC-13组自发交替反应率显著增高见附图4、图5。
在新物体辨别实验中,ZCY-02显示出改善形象辨别记忆障碍的趋势,ZCY-15能显著改善痴呆模型大鼠的形象辨别记忆障碍(见图7、 8和9)。与假手术组相比,模型组大鼠1h优先指数和辨别系数显著降低;与模型组相比,JCC-02组、JCC-06组、JCC-11组以及JCC-15组大鼠1h优先指数显著增加(见图10和11);与模型组相比,JCC-06 组、JCC-11组以及JCC-15组大鼠1h辨别系数显著增加(见图12和 13)。
水迷宫实验结果表明,各组之间游泳速度没有显著差异,可以排除游泳速度不一致对逃避潜伏期的影响(见图2-18~2-19);与假手术组相比,模型组大鼠定向航行训练第三天、第四天、第五天的逃避潜伏期及游泳总路程均显著增加(见图2-22~2-23),提示模型组大鼠出现空间学习记忆障碍。与模型组相比,JCC-12组大鼠第三天逃避潜伏期显著降低,JCC-05、JCC-06、JCC-11、JCC-12、JCC-15 以及JCC-16组大鼠第三天游泳总路程均显著降低;JCC-04、JCC-06、 JCC-07、JCC-09以及JCC-12组大鼠第四天逃避潜伏期显著降低, JCC-04、JCC-05、JCC-06、JCC-07、JCC-09、JCC-10、JCC-11以及 JCC-12组大鼠第四天游泳总路程均显著降低;JCC-02、JCC-04、 JCC-05、JCC-06、JCC-07、JCC-09、JCC-11以及JCC-12组大鼠第五天逃避潜伏期显著降低,JCC-02、JCC-04、JCC-05、JCC-07、JCC-09、 JCC-11、JCC-12、JCC-15以及JCC-17组大鼠第五天游泳总路程均显著降低(见图16、17和18)。
