Description

四氢异喹啉类衍生物、其制备方法及其医药用途
技术领域
本发明涉及药物化学领域,具体涉及一类四氢异喹啉衍生物、它们的制备方法、含有这些化合物的药用组合物以及它们的医药用途,特别是作为κ-阿片受体激动剂在镇痛上的用途。
背景技术
κ-受体与μ-、δ-、σ、和ORL-1受体同属于阿片受体家族。以吗啡为代表的μ-受体激动剂药物有着很强的镇痛效力,但是由于依赖性、成瘾性等副作用使其在临床上的应用受到很大的限制。中枢选择性κ-受体激动剂不仅可以用于镇痛且免除吗啡样副作用。它可用于镇痛、消炎镇痛、抗痛觉过敏、治疗分娩疼痛;用作利水剂、止痒剂;以及用于抗惊厥治疗、抗高血压、神经保护、治疗HIV感染和用于可卡因、吗啡成瘾的戒断等。因此,开发选择性κ-受体激动剂药物具有广阔的应用前景。
发明内容
本发明公开了一系列新的四氢异喹啉衍生物。经放射性配体结合实验和初步的动物体内镇痛试验显示,本发明化合物对κ-受体具有很高的亲和性和选择性,在小鼠热板镇痛试验研究当中,显示出了较强的镇痛活性。

放射性配体受体结合实验
实验分总结合管和非特异结合管,另设几组样品管加不同浓度竞争配体。总结合管加相当于20μg的表达的膜受体蛋白和[3H]diprenorphine(0.5nM)(1.44Pbq.mol-1广谱阿片拮抗剂,Amersham公司),相对应的非特异结合管另加1μM的纳络酮(广谱阿片拮抗剂,Sigma公司),样品管加不同浓度待筛选的化合物,用50mM Tris(Amresco公司)-HCl(pH 7.4)调节至终体积100μl。在30℃孵育30min,然后置冰水中终止反应。在Millipore样品收集器上经GF/(Whatman)玻璃纤维滤纸负压抽滤。用冰冷的50mM Tris-HCl(pH 7.4)冲洗三次,每次4ml,滤纸烘干后,置于0.5ml Eppendorff管,加0.5ml亲脂闪烁液(上海试剂一厂),Beckman LS 6500多功能液体闪烁计数仪测定放射性强度,计算抑制率,每一浓度为三复管,每一次独立实验3-4次。
计算方法:
IC50值用Prism 4.0软件计算。
Ki=IC50/(1+[L]/Kd),([L]为所加标记配体的浓度,Kd为放射性配体的平衡解离参数)。

小鼠热板镇痛筛选:
正常小鼠(昆明种小鼠,雌性,18~22g)挑选:实验室温度控制在22℃左右,测痛仪(型号GJ-8402,浙江宁海白石电子医药仪器厂)热板温度调节至55℃,记录小鼠自投入热板至出现舔后足时间作为该小鼠的痛域值,共测2次,每次间隔20分钟,以平均值不超过30秒为合格小鼠。
实验组小鼠:将合格小鼠随机分组,每组10只。皮下给予化合物I-6。各组均在给药后5,15,30,5,60分钟测定小鼠痛反应时间一次,超过1分钟认为该药有效。
