Description
本发明涉及新型杂环氨甲基化合物、其制备方法及含有它们的药物组合物。
业已描述过许多含有苯并噁唑啉酮、苯并噻唑啉酮或苯并噁嗪酮结构的杂环烷基胺。
欧洲专利EP0110781描述6-(2-氨基乙基)苯并噁唑啉酮作为催眠药和治疗心机能不全的药物。欧洲专利申请EP 0281309描述含哌嗪乙基-或-丁基苯并噁唑啉酮和-苯并噻唑啉酮结构的化合物可用作精神抑制药。
法国专利FR 2035749描述了氨烷基苯并噁嗪酮可用于治疗中枢神经系统疾病。
出版物“II farmaco”89,44(1),77-88描述了芳基哌嗪丁基苯并噁唑啉酮以及它们的主要止痛性能。
专利申请EP 0223674描述了7-酰基苯并噁嗪酮及其衍生物具有抗动脉粥样硬化性能和正常脂血(normolipemic)性能。
专利申请EP 0478446描述了具有结合性能且对5-HT1A血清素能性受体具有很高亲和力的杂环乙基-和丁基胺类。
申请人现已发现新的杂环氨甲基化合物,更具体地说是氨甲基苯并噁唑啉酮、-苯并噻唑啉酮和-苯并噁嗪酮化合物,与现有技术的化合物相反且最令人吃惊的是,它们不再对5-HT1A和D2受体不具有弱亲和力。同时,这些新的化合物对D4受体具有优异的亲和力,与现有技术文献中所提到的化合物进行比较表明后一化合物实际上对这些D4受体不具亲和力。
D4受体集中在控制情绪和记忆力所涉及的皮质边缘(Corticolimbic)结构(额皮层、所神经核和海马)中(Bloom和Kupfer,精神药理学(Psychopharmacology),“第4代进展(The fourthgeneration of progress)”,Raven Press,New York 1995;Meador-Woodruff等,“在人纹状体和新大脑皮质中的多巴胺受体mRNA表达”,神经精神药理学(Neuropsychoplarmacology),1996;15:17-29)。在这些结构中,副增殖(Subpopulation)集中在GABA素能型神经元上,这些神经元也在情绪和识别功能的调节中起关键作用(Boom和Kupfer,1995(已引用);Mrzkjak等,“多巴胺D4受体在灵长目大脑的GABA素能神经元中的集中”,自然(Nature),1996;381:245-248)。某些研究表明,D4受体的密度在精神病患者中增加,与此同时氯氮平对D4受体显示高亲和力(Van Tol等,“对精神抑制药氯氮平具有高亲和力的人多巴胺D4受体的基因克隆”,Nature,1991;350:610-614)。此外,去甲肾上腺素-一种在精神病、焦虑和抑郁状态以及识别和注意力疾病中所涉及的神经递质(Bloom和Kupfer,1995(已引用))对D4受体具有高亲和力(Lanau等,“肾上腺素和去甲肾上腺素在人重组D4.4受体上用作有效激动剂”,美国神经科学会志(Am.Soc.Neurosci.,1995;21:252.2)。这些结果表明本发明产品在治疗神经分裂症、焦虑、抑郁、药物滥用、冲动状态(例如攻击性)和记忆识别疾病中有价值。此外,在脊髓的浅表层中高浓度的D4受体(Matsumoto等,“用于多巴胺D4受体的mRNA在人大脑皮层和纹状体中的低水平”,神经化学杂志(J.Neurochem.)1996;66:915-919)暗示在治疗疼痛状态(例如神经病或偏头痛)中有价值。

式III、IV、IVb和VI化合物是新的且本身以与式(I)化合物相同的方式形成本发明的一部分,它们构成式(I)化合物的合成中间体,但其中A表示氧原子且R1’表示甲基的式III化合物例外(Renard等,药物协会公报(Bull.Soc.Pharm.Lille),1979,2-3,125-138)。更具体地说,在这些化合物中,下列是优选的:·3-甲基-6-甲酰基苯并噻唑啉酮,·3-甲基-6-(羟甲基)苯并噁唑啉酮,·3-甲基-6-(羟甲基)苯并噻唑啉酮,·6-(羟甲基)苯并噁唑啉酮,·6-(羟甲基)苯并噻唑啉酮,·3-甲基-6-(卤代甲基)苯并噁唑啉酮,·3-甲基-6-(卤代甲基)苯并噻唑啉酮,·6-(卤代甲基)苯并噁唑啉酮,·6-(卤代甲基)苯并噻唑啉酮。

式(I)化合物具有有利的药理性能。
结合试验表明本发明化合物为非常有效的D4受体配位体。这种亲和力伴随着对其他受体,尤其是D2的极大选择性。这对于上述现有技术化合物对D4受体不具有亲和力,相反对D2受体具有高亲和力的事实来说都更令人惊讶。
本发明化合物毒性低,且由于其受体特性它们应在精神分裂症和各种精神病、情绪和识别功能的调节、焦虑、抑郁、药物滥用、冲动状态和记忆识别疾病以及偏头痛状态中具有良好的活性。
本发明的主题还有单独含有至少一种通式(I)化合物或其与可药用酸或合适时与可药用碱的加成盐作活性成分或与一种或多种惰性无毒赋形剂组合的药物组合物。

剂量随患者的年龄和重量、疾病的性质和严重程度以及给药途径而变。给药途径可以是口服、经鼻、直肠或胃肠外给药。
一般来说,单位剂量对精神行为疾病在0.05mg至30mg间变化,每24小时一至三个剂量。
下列实施例说明本发明但决不限制本发明。
1H核磁共振谱使用TMS(四甲基硅烷)作内标进行。化学位移以每百万的份数(ppm)表达。红外光谱以含约1%待分析产品的溴化钾片形式记录。
除非另有所指,制备并不构成本发明的一部分但可用于合成本发明化合物。

本发明化合物的药理研究
实施例A:对D4、D2和5-HT1A受体的体外亲和试验
对D4、D2和5-HT1A受体的体外亲和试验按经典的结合技术进行。
这些研究的结果表明本发明化合物对5-HT1A和D2受体的Ki为10-7M左右,等于申请EP 478446的化合物的亲和力的约1/100。
对D4.4受体的亲和力用[3H]螺环哌丁苯(NEN,lesUlis,France)通过竞争性试验测定。由用人D4.4受体转染的CHO细胞制备的膜购自Receptor Biology Inc.(MD,USA)。这些膜(30μg膜蛋白)分三份用0.5nM[3H]螺环哌丁苯和冷配位体以最终体积0.5ml在25℃下温育60分钟。温育缓冲液含有50nM TRIS-HCl(pH7.4)、120mM NaCl、5mM KCl、5mM MgCl2和1mMEDTA。非特异性结合用10μM氟哌丁苯测定。在温育结束时,通过用0.1%聚乙烯亚胺浸渍的WHATMAN GF/B过滤器过滤温育培养基并用2ml冷却的缓冲液洗涤3次。用液体闪烁计数法测定残留在过滤器上的放射性。使用“PRISM”软件(Graph PadSoftware Inc.,S.Diego,USA)通过非线性回归分析结合等温线,以确定IC50值。后者通过Cheng-Prusoff方程转化为离解常数(Ki):
Ki=IC50/{(L/Kd)-1}
其中L为[3H]螺环哌丁苯的浓度,Kd为人D4.4受体(70pM)的[3H]螺环哌丁苯离解常数。
对于D4.4受体,亲和力Ki为10-8-10-9左右,而EP478446的化合物仅具有10-6M左右的亲和力。实施例B:在人D4.4受体上效力的测定
通过测定G蛋白因刺激[35S]GTPγ S(NEN,LesUlis,France)的结合产生的活化度而测定该效力。由用人D4.4受体转染的CHO细胞制备的膜购自Receptor BiologyInc.(MD,USA)。这些膜(50μg膜蛋白)分三份用0.1nM[35S]GTPγS和冷配位体以最终体积0.5ml在25℃下温育20分钟。温育缓冲液含有20mM HEPES(pH7.4)、3μM GDP、3mM MgCl2和100mM NaCl。在温育结束时,通过用水浸渍的WHATMAN GF/B过滤器过滤温育培养基并用2ml冷却的缓冲液洗涤3次。通过液体闪烁计数技术测定残留在过滤器上的放射性。使用“PRISM”软件(Graph Pad Software Inc.,S.Diego,USA)通过非线性回归分析结合等温线,以确定EC50值和效力(Emax)值。效力表示为由多巴胺诱发的[35S]GTPγS的结合的刺激百分数。
对于拮抗试验,在加入[35S]GTPγS之前以固定浓度的多巴胺用拮抗剂预温育这些膜30分钟。通过下列等式将IC50值转化为拮抗剂效力常数(Kb):
Kb=IC50/{[拮抗剂]/EC50]+1}其中[拮抗剂]为拮抗剂浓度,EC50为不存在拮抗剂(仅有多巴胺)时测得的EC50。对实施例1,Kb为2.39±1.10nM。对实施例3,Kb为16.1±5.0nM。实施例C:急性毒性
在以650mg/kg的剂量口服给药于一组8只小鼠(26±2g)后评价急性毒性。在第一天至处理后两周内每天以规则间隔观察这些动物。
显然本发明大多数化合物完全无毒。大多数在以650mg/kg剂量给药后不引起死之,且在给予该剂量后通常注意不到任何紊乱。药物组合物
