Description
技术领域
本发明涉及作为治疗活性化合物的通式I的磺酰基噁唑胺或其生理学上可接受的盐或溶剂化物。
本发明进一步涉及通式I磺酰基噁唑胺作为治疗活性化合物的用途。
本发明也涉及通式I磺酰基噁唑胺在生产控制中枢神经系统疾病的药物制剂中的用途。
背景技术
一些通式I化合物见于各种较早的出版物。因此,式I化合物的制备描述于V.A.Chervonyi等,Ukr.Khim.Zh.(Russ.Ed.)1991,57(4),415-418或对应于V.A.Chervonyi等,J.Org.Chem.USSR(英译本)1988,24,401的V.A.Chervonyi等,Zh.Org.Khim.1988,24(2),453-4中。
本发明的目的是寻找磺酰基噁唑胺的新的有用的性质,详细地说是确认作为治疗活性化合物和/或可以导致使用磺酰基噁唑胺作为治疗活性化合物和/或生产药物制剂的化合物。
我们发现,式I化合物及其药学上的活性盐对5-HT6受体意外地具有选择性亲和力以及良好的耐受性。它们呈现出5-HT6-拮抗作用或5-HT6激动作用。
5-HT6受体构成5-HT受体的一个亚家族。神经递质5-羟基色胺(5-HT),也称为血清素,它是大脑中的一个重要的调节神经递质,其作用得到受体族的协助,在目前的知识水平,该受体族含有13G蛋白质偶连受体和一个离子通道。
已发现在脑中5-羟色胺5-HT6受体的最大密度存在于嗅觉结节、听神经核(nucleus accumbens)、纹状体、齿状回及海马的CA1-3区。这些部位在很大程度上与精神病疾病有关,所述疾病如精神分裂症或抑郁症。此外,从动物实验我们知道给予5-HT6反义寡核苷酸引起一种行为综合征,该综合征相当于多巴胺激动剂引起的症状。另外,病理生理学证实在精神分裂症中多巴胺能的神经递质体系的机能亢进(精神分裂症的多巴胺假说)。可是,已经证实在各型抑郁症中多巴胺体系的机能障碍。在临床实践中采用一些已确定的或替代的新疗法治疗这些精神病,所述疗法中大量结合5-HT6受体。在此可详细地提到非典型的抗精神失常药(如氯氮平)和三环抗抑郁药(如阿米替林)。
另外,在动物实验研究中发现,脑中5-HT6受体控制胆碱能的神经递质。胆碱能药用于记忆障碍的疾病如早老性痴呆。
因为这些原因,可以推定5-HT6受体与精神病学和神经病学的疾病,如特别是精神分裂症、抑郁症及早老性痴呆有关。
因此式I化合物及其生理上可接受的盐适宜作为中枢神经系统疾病的治疗活性化合物。式I化合物及其生理上可接受的盐或溶剂化物特别适合用于治疗精神病、精神分裂症、燥狂抑郁症(B.L.Roth等,J.Pharmacol.Exp.Ther.1994,268,1403-1410)、抑郁症(D.R.Sibley等,Mol.Pharmacol.1993,43,320-327)、神经疾病(A.Bourson等,J.Pharmacol.Exp.Ther.1995,274,173-180)、记忆障碍、帕金森氏综合症.肌萎缩性侧索硬化、早老性痴呆、亨廷顿舞蹈病(A.J.Sleight等,Neurotransmissions 1995,11,1-5)、食欲过盛、神经性食欲缺乏或其它饮食障碍、强迫行为或月经前综合症。
发明内容
本发明涉及作为治疗活性化合物的式I化合物或其生理上可接受的盐或溶剂化物。

式I化合物通常可通过商业渠道获得或按照以下合成方案合成(为此参考V.A.Chervonyi等,Ukr.Khim.Zh.(Russ.Ed.)1991,57(4),415-418或对应于V.A.Chervonyi等,J.Org.Chem.Ussr(英译本)1988,24,401的V.A.Chervonyi等,Zh.Org.Khim.1988,24(2),453-4)。
合成方案:
在上面所示的合成方案中,式II的原料与三氯乙酸盐反应得到化合物III。式III再与亚硫酰氯反应并随后与式V的亚磺酸钠反应产生式VI的芳基乙烯基砜,该砜通过与式VII的胺反应环化得到式I的磺酰基噁唑胺。关于此点,式II到VII的取代基Ar、Z、R1和R2具有此前指明的优选或特别优选的含义。
合成方案中所述反应的适宜反应条件见参考资料V.A.Chervonyi等,Ukr.Khim.Zh.(Russ.Ed.)1991,57(4),415-418或对应于V.A.Chervonyi等,J.Org.Chem.USSR(英译本)1988,24,401的V.A.Chervonyi等,Zh.Org.Khim.1988,24(2),453-4或见标准参考书如Houben-Weyl,Methoden der Organischen Chemie[有机化学方法],Georg-Thieme-Verlag,Stuttgart。在此情况下,也可以变化使用,所述变化是本领域熟悉的,但是在此不进一步详细描述。
可以用一种酸将式I的碱转化成为相关的酸加成盐,例如使等当量的碱与酸在惰性溶剂如乙醇中反应并随后蒸发。对于这类反应,适宜的酸特别是那些产生生理上可接受的盐的酸。因此,可以使用无机酸,如硫酸、硝酸、氢卤酸如盐酸或氢溴酸、磷酸如正磷酸、氨基磺酸,还可使用有机酸,特别是脂肪族的、脂环族的、araliphatic、芳香的或杂环单或多元羧酸、磺酸或硫酸,例如甲酸、乙酸、丙酸、新戊酸、二乙基乙酸、丙二酸、丁二酸、庚二酸、富马酸、马来酸、乳酸、酒石酸、苹果酸、柠檬酸、葡糖酸、抗坏血酸、烟酸、异烟酸、甲磺酸或乙磺酸、对-甲苯磺酸、萘单或双磺酸或十二烷基硫酸。与生理上不可接受的酸所成的盐如苦味酸盐可用来分离和/或纯化式I化合物。
按照以下方法测定式I化合物与5-HT6受体的结合:
将受试物按1mM的浓度溶解于DMSO中并用实验缓冲液(20mMHEPES,0.1%抗坏血酸,用NaOH调节到pH7.4)稀释到需要的浓度(0.1nM到10μM)。
将20μl各物质的溶液在37℃与80μl 3H-LSD溶液(TRK-1041,Amersham Pharmacia,Freiburg,spec.Act.80-90 Ci/mMol,该批为1nM)和100μl膜悬浮液(5-HT6受体、RB-HS6,Biotrend,Cologne,25-30μg蛋白质)孵育1小时。通过用0.1%聚乙烯亚胺水溶液预处理1小时的GFB滤器(Whatman)过滤反应混合物。用3ml实验缓冲液洗涤滤器三次,将滤器[sic]转移到微型瓶(minivials)中并在加入Ultima Gold(Packard,Frankfurt)后,用一个液体闪烁计数器测量放射活性。用RS1(BBN软件公司)的内部(in-house)程序方法进行评估和IC50测定。
式I化合物对5-HT6受体具有选择性的亲合力,其抑制常数IC50值低于4μmol/l。
本发明进一步涉及通式I化合物在生产控制中枢神经系统疾病的药物制剂时的用途。
本发明进一步涉及通式I化合物在生产治疗以下疾病的药物制剂时的用途:精神病、精神分裂症、燥狂抑郁症、抑郁症、神经疾病、记忆障碍、帕金森氏综合症、肌萎缩性侧索硬化、早老性痴呆、亨廷顿氏舞蹈病、食欲过盛、神经性食欲缺乏或其它饮食障碍、强迫行为或月经前综合症。
