Abstract
本发明涉及多巴胺D3受体配体在生产治疗肾功能紊乱的药物中的应用。受体配体优选为受体拮抗剂。本发明特别涉及用于治疗肾小球超滤(glomerular hyperfiltration)意义上的肾小球滤过率异常性肾功能紊乱的药物。
Description
本申请是申请日为2000年4月28日、发明名称为“多巴胺D3受体配体在生产肾功能紊乱治疗药物中的应用”的发明专利申请的分案申请,原申请的中国专利申请号为00809977.4。
技术领域
本发明涉及选择性多巴胺D3受体配体在生产肾功能紊乱治疗药物中的应用。
受体配体优选为受体拮抗剂。
本发明特别涉及用于治疗肾小球超滤(glomerular hyperfiltration)意义上的肾小球滤过率异常性肾功能紊乱的药物。
背景技术
有证据表明,多巴胺D3受体在肾脏、尤其是肾单位中表达(参见D.P.O’Connell等,Hypertension,1998,32,886)。
DE-A 4223921一般性介绍了多巴胺受体拮抗剂在治疗肾功能进行性恶化中的应用,但是没有指明多巴胺受体拮抗剂的具体亚型。
G.Luippold等在Naunyn-Schmiedeberg’s Arch.Pharmacol(1998)358:690-693中介绍了在没有病理生理学变化的纯人工功能状态下,研究特定的D2和D3受体拮抗剂对肾脏血液动力学和排泄功能的影响。
L.D.Asico等(J.Clin.Invest.,Vol.102(1998),493-498)介绍,阻断D3受体使肾素产生以及肾性钠潴留增加,因而导致肾素依赖性高血压。
某些疾病发生肾小球毛细管硬化,由此引起肾小球滤过率异常,所述疾病例如糖尿病、高血压、感染性或非感染性肾小球肾炎、上行性泌尿道感染、镰状细胞性贫血或在单侧肾切除手术后的代偿性肥大。
几乎所有肾小球肾炎患者以及1/3以上的糖尿病患者发生肾功能进行性恶化。
肾小球硬化引起的肾功能紊乱也称为糖尿病性肾病,其组织学特征为弥漫性肾小球毛细血管壁增厚和肾小球膜改变,其原因是基底膜样物质或球状纤维蛋白沉积。因此发生超滤意义上的肾小球过滤异常。
肾小球肾炎同样如此,肾小球基底膜变化导致肾小球滤过率异常。
发明内容

令人惊奇的是,使用这种多巴胺D3受体配体制备的控制肾功能失调的药物,特别能够改善过滤功能性病理生理学失调。
用糖尿病性肾病实验动物模型研究了多巴胺D3受体拮抗剂的作用。给予大鼠链脲菌素而产生糖尿病,在14天内出现显著肾小球超滤。假如用多巴胺D3受体拮抗剂亚慢性地治疗以该方法诱发产生糖尿病的大鼠,则不会发生糖尿病性超滤。
多巴胺D3受体配体还可以与其它活性化合物组合用于生产治疗上述综合征的药物。ACE抑制剂如群多普利和AT1拮抗剂如氯沙坦尤其适合这种组合。此外,也可以与钙拮抗剂或β-阻滞剂组合。
方法
将60mg/kg溶解于柠檬酸盐缓冲液(21mg柠檬酸/ml重蒸馏水)的链脲菌素腹膜内注射入180-200g体重的雄性Sprague-Dawley大鼠体内。如果24小时后晚上静脉血葡萄糖浓度至少为180mg/dl,则认为成功诱发了糖尿病。糖尿病大鼠的血糖值为350-450mg/dl。因此没有必要进行胰岛素替代治疗。实验大鼠体重每天增加约5g。将相同量的柠檬酸缓冲溶液经腹膜注射入非糖尿病的时间对照大鼠体(CON)内。它们的血糖值为90-1120mg/dl。
在确定成功诱发糖尿病后,使大鼠在标准笼内适应标准饲料(Altromin 1320),自来水任意饮用。经不同的药物治疗(通过饮水给药),形成下面四组实验:
CON(1)没有外加治疗措施的非糖尿病动物(时间对照)
DM-VHC(2)没有外加治疗措施的糖尿病动物(糖尿病对照)
DM-SUL(3)用舒必利治疗的糖尿病动物(25ml/kg/d)
DM-D3(4)用D3-A治疗的糖尿病动物(D3-A:根据实施例(7)的D3受体拮抗剂(5mg/kg/d);D3-A2:根据实施例(11)的D3受体拮抗剂)。
记录每天吸收的液体量。每三天检测一次实验动物的体重及血糖浓度。在十二天后,将实验动物置于代谢笼进行二十四小时尿液收集。根据Lowry介绍的标准方法测定尿液中的蛋白质浓度。为此,使样品与1M的NaOH温育后,用福林氏试剂(苯酚-Ciocalteu’s)引发颜色反应,用光度计测定颜色强度。用白蛋白特异性放射免疫测定(RIA)测定尿液白蛋白浓度。应用Biermann的试剂盒(KHAD 2:白蛋白放射免疫测定),它用抗人类血清白蛋白的多克隆抗体(山羊)和125I-标记的人类血清白蛋白作为示踪剂。14-16天后,用硫喷妥钠(80mg/kg)麻醉实验动物并用聚乙烯导尿管进行颈静脉、颈动脉以及膀胱插管。通过3H-菊粉肾脏廓清率测定肾小球滤过率(GFR)。此外在实验期间记录其平均动脉血压(MAP)和心率(HR)。在廓清率实验结束时,切除肾脏并进行组织病理学检查。
实验结果
对清醒动物收集的二十四小时尿液进行检测,如果与时间对照大鼠相比,没有治疗的糖尿病动物尿液存在显著蛋白尿(proteinuria)(133与46mg/d)和更显著的白蛋白尿(albuminuria)(118与23μg/d),说明其肾小球过滤屏障受损。用舒必利治疗的糖尿病动物中,这种病理性白蛋白尿只有轻微降低(101μg/d)而蛋白尿甚至进一步加重(178mg/d)。与此相反,用根据实施例7的D3-A治疗的糖尿病动物,不但蛋白尿减轻(113mg/d),而且完全抑制了白蛋白尿,只有18μg/d。
舒必利和D3-A1的选择性见WO 96/02520实施例42介绍。
在廓清率研究中,与时间对照动物相比,未治疗糖尿病麻醉动物(2)的肾小球滤过率显著增加(1.10与0.83ml/min),说明存在糖尿病性肾小球超滤。舒必利和D3-A治疗的糖尿病动物((3)和(4)的糖尿病性超滤均得到了抑制,几乎为正常的GFR(分别为0.71和0.83ml/min)。
与健康的时间对照动物(1)相比,没有治疗的糖尿病动物(2)除了整个肾脏肥大性增大外,组织病理学研究显示其肾小球显著增大(表示为每20个显微镜检测区的平均值)。在用舒必利治疗的糖尿病动物(3)中也观察到类似的肾小球肥大,但是用D3-A1治疗的糖尿病动物(4)却没有这样的肾小球肥大。
成年非糖尿病大鼠的肾脏正常湿重为0.9±0.1g/100g体重。糖尿病大鼠(DM-VHC)的肾脏湿重为1.1±0.04g/100g体重,说明为初期肾脏肥大。用D3-A2治疗后,肾脏湿重恢复正常,为0.96±0.03g/100g体重。
总之,这些在糖尿病活体模型发现的数据显示:用多巴胺D2受体药理学抑制剂(舒必利)和多巴胺D3受体药理学抑制剂进行亚慢性治疗,使糖尿病性肾病病程中的肾脏血液动力变化显著减轻。
用D3-A2(30mg/kg体重/天)进行亚慢性治疗明显减轻肾小球超滤以及糖尿病性肾脏超灌注。肾脏初期肥大也显著减轻。
此外,对各治疗组进行比较表明,多巴胺D3受体拮抗剂D3-A1和D3-A2消除糖尿病性肾病发生的结构性减少性(eliminated)肾内变化,而多巴胺D2受体拮抗剂舒必利没有此作用。在功能上,这种区别还表现为多巴胺D3受体拮抗剂D3-A显著减少病理性蛋白质和白蛋白排泄,而多巴胺D2受体拮抗剂没有此作用,病理性蛋白质和白蛋白排泄被认为是肾功能受损加重的重要标志。总而言之,研究结果清楚表明,给予多巴胺D3受体拮抗剂例如D3-A可有利地治疗糖尿病性肾病。
