Description
发明所属技术领域
本发明涉及作为精神病药有用的多巴胺D4受体拮抗化合物。
背景技术
抗精神病药可用于治疗精神分裂症以及脑血管障碍·老年痴呆中的行动问题(攻击性行为、精神兴奋、徘徊、谵妄等)。但是,以前的抗精神病药多巴胺D2受体拮抗剂的副作用即锥体外系障碍很强,这成为很大的问题。
一方面,近年来发现的多巴胺D4受体的构造以及性质与多巴胺D2受体很相近,最大的不同是其脑内分布。多巴胺D4受体的脑内分布使得其在与精神分裂发病相关的大脑皮层前叶以高浓度存在,但在与锥体外系障碍相关的线条体中很少。因此,多巴胺D4受体拮抗剂与多巴胺D2受体有不同的副作用,因此有极大的可能性成为不伴有锥体外系障碍的新的精神分裂症治疗药。(自然Nature,350,610~614(1991);Nature,358,109(1992);Nature,365,393(1993);Nature,365,441~445(1993))。
作为这种化合物有氯氮平。有报告显示氯氮平对多巴胺D4受体的亲和性比对多巴胺D2受体的亲和性高(Nature,350,610~614(1991))。另外,有报告显示氯氮平在临床试验中,由于与多巴胺D2受体拮抗剂不同,因此对有药物抗性的精神分裂症以及隐性症状有效,且锥体外系障碍少。(普通心理学文献Arch.Gen.Psych.,45,789~796(1988))。但是,氯氮平会引发称作无粒细胞症的血液毒症,并有死亡例的报告。(临床数据总结Summary and Clinical Data.Sandoz,Canada Inc.(1990)),这一点成为其最大的缺点。
因此,不具有这样的副作用的多巴胺D4受体拮抗剂,产生锥体外系障碍的可能性极低,作为精神分裂症等的治疗药有用性很高。
本发明的目的是提供不产生锥体外系障碍的,具有抗精神病作用的多巴胺D4受体拮抗化合物。

试验例[受体结合试验]1、多巴胺D4受体结合试验
使用发现了人D4.2受体的中国仓鼠卵巢(CHO)细胞膜作为受体标本。
用[3H]螺环哌啶酮作为[3H]标记的配体。
用[3H]标记的配体的结合反应按照欧洲药理学杂志Eur.J.Pharmacol.,233,173(1993年)中记载的以下方法进行。
人D4.2受体结合试验:将人发现了D4.2受体的CHO细胞膜、[3H]螺环哌啶酮(0.5nM)和被检药物在含有5mM EDTA、1.5mM CaCl2、5mMKCl、120mM NaCl的50mM Tris盐酸缓冲液(pH7.4)中,在27℃反应2小时。
反应完成后,用玻璃漏斗(GF/B)抽滤,用液体闪烁光谱仪测定滤纸的放射性。
将在10μl卤吡醇存在下反应时的结合作为[3H]螺环哌啶酮的非特异性结合,总结合与非特异性结合之差作为特异性结合。将一定浓度的[3H]螺环哌啶酮和变化浓度的被检药物在上述条件下进行反应,得到抑制曲线,从该曲线求出50%抑制[3H]螺环哌啶酮结合时被检药物的浓度(IC50),结果如表3所示。
2、多巴胺D2受体结合试验
使用大鼠线条体膜作为受体标本。
使用[3H]ラク口プリド作为[3H]标记的配体。
用[3H]标识的配体的结合反应按照Mol.Pharmacol.,43,749(19933年)中记载的以下方法进行。
受体标本的调制:将大鼠线条体在50mM Tris盐酸缓冲液(pH7.4)中匀化,在48,000×g离心分离,将残渣用Tris盐酸缓冲液1次洗净。将残渣悬浮于含有120mM NaCl、5mM KCl、2mM CaCl2、1mM MgCl2的50mM Tris盐酸缓冲液(pH7.4)中,作为膜标本。
多巴胺D2受体结合试验:将膜标本(0.5mg蛋白质/ml)、[3H]ラク口プリド(1nM)和被检药物在25℃反应1小时。
反应完成后,用玻璃漏斗(GF/B)抽滤,用液体闪烁光谱仪测定滤纸的放射性。
将在10μl卤吡醇存在下反应时的结合作为[3H]ラク口プリド的非特异性结合,总结合与非特异性结合之差作为特异性结合。将一定浓度的[3H]ラク口プリド和变化浓度的被检药物在上述条件下进行反应,得到抑制曲线,从该曲线求出50%抑制[3H]ラク口プリド结合时被检药物的浓度(IC50),结果如表3所示。
产业上的可利用性
