Abstract

公开了式(Ⅰ)表示的联苯基衍生物或其药理上可接受盐,其中取代基见说明书,它具有多巴胺2受体拮抗作用和/或5-羟色胺2受体拮抗作用,在临床上用于治疗和改善精神疾病。还公开了中间体化合物,即式(XXVⅡ)的苯基哌嗪衍生物或其盐,其中取代基定义见说明书。

Description

苯基哌嗪衍生物
本发明涉及一种苯基哌嗪衍生物。
本发明涉及联苯基衍生物。更详细地说,本发明涉及具有多巴胺2受体拮抗作用和/或5-羟色胺2受体拮抗作用并且临床上用作治疗和改善精神错乱药物的联苯基衍生物,这些精神疾病包括脑血管疾病,由于老年性痴呆引起的过分行为,精神兴奋,漂游癖,妄想,幻觉,运动过度,精神分裂症,情绪紊乱,抑郁症,神经官能症,精神生理疾病和焦虑性神经机能症。
老年人中经常出现精神错乱如脑血管紊乱和痴呆,随着老龄社会的逼近,这成了严重的问题。在很多情况下,这些疾病伴随具体表现为妄想,幻觉,运动过度,漂游癖,精神兴奋或其它症状的精神和/或行为疾病。这些症状不但对病人本身有不利作用,而且必需每天护理,给病人周围的人也带来治重的负担。在这种情况下,不仅病人及其家属,而且社会都希望在医学上开发出能治疗上述精神疾病的高临床应用价值的药物。
目前仅胺甲磺茴胺被授权作为上述疾病的治疗药和改善药,但也使用抗精神分裂症药卤吡醇,尽管这些疾病不包含在该药有效的适应症中。
作为具有抗精神病活性的新化合物,苯并异噻唑衍生物和苯并异恶唑衍生物公开于欧洲专利申请号196132中,吡啶衍生物公开于美国专利号5021421中。
胺甲磺茴胺和卤吡醇是具有多巴胺2(D2)受体拮抗作用的药物。这类药物有引起锥体束外综合症包括肌张力障碍(肌张力过度或肌张力减退),少动症(失运动能),运动过度(不正常运动)以及不利反应等问题,尽管该药临床上是有效的。
在美国,英国和加拿大已授权在上述欧洲专利申请号196132中公开的苯并异恶唑的代表例子Risperidone作抗精神分裂症药。然而,这种药也存在问题,因为该药高α1阻断活性引起副反应-血压降低,心电图中QTc间隔拖长导致心律不齐,尤其当对老龄病人给药时更不理想。
上述美国专利号5021421中公开的吡啶衍生物如胺甲磺茴胺或卤吡醇对多巴胺2受体也表现出强拮抗作用,因此担心它们引起锥体束外综合症,而且,该吡啶衍生物至今还未临床应用,所以它们在延迟应用上的安全性并不明显。
如上所述,还未发现任何治疗或改善精神错乱如脑血管疾病,由于老年性痴呆引起的过分行为,精神兴奋,漂游癖,妄想,幻觉,运动过度,精神分裂症,情绪紊乱,抑郁症,神经官能症,精神生理疾病和焦虑性神经机能症的药物,它具有高度临床实用性及极好的安全性。
本发明的一个目的是提供新的联苯基衍生物和其药理上可接受盐,它们对多巴胺2受体拮抗和/或对5-羟色胺2受体拮抗,临床上用作治疗和改善精神疾病的药物,与先有技术中多巴胺2受体拮抗剂如胺甲磺茴胺和卤吡醇相比在不利的锥体束外综合症方面有所改善,并且排除了由上述苯并异恶唑衍生物(如Risperidone)引起的副反应如血压降低和诱发心律不齐。
本发明的另一目的是提供制备上述联苯基衍生物。
本发明的另一目的是提供苯基哌嗪衍生物和其盐,它们用于生产上述联苯基衍生物和其药理上可接受盐的中间体。
本发明人广泛研究,发现了对精神疾病极其安全和有用的治疗和改善药,它们对多巴胺2受体拮抗,不引起锥体束外综合症,血压降低,诱发心律不齐或其它副反应,同时他们的着眼点放在既对多巴胺2受体拮抗又对5-羟色胺2受体拮抗作用的化合物。结果,他们发现了特定的联苯基衍生物及其药理上可接受盐,它们是对精神疾病具有极好治疗作用和改善作用的新化合物,它们安全性极好,并且解决了上述问题。基于此发现完成本发明。
因此,本发明提供了由下面式(Ⅰ)表示的联苯基衍生物或其药理上可接受的盐:
