通过分离或纯化同样使药物学上不适合的盐有了用途。仅在药物学上可使用的、无毒性的盐成功地被用于治疗,因此它们是优选的。
式Ⅰ的化合物具有很有价值的药物学性能。它对兴奋性氨基酸受体例如对AMPA受体、NMDA(Kainate)受体和/或NMDA受体的甘氨酸结合位置具有高的结合亲和性。对上述受体的亲和性根据结构是非选择性的或选择性的。所选择的式Ⅰ的化合物特别地对AMPA-和/或NMDA(Kainate)-结合位置具有强的亲和性和对NMDA受体的甘氨酸结合位置具有次强的亲和性。
本发明提供的化合物和其盐的结合力可以通过在鼠(小鼠,大鼠)脑膜的体外X射线照相学借助于[3H]-AMPA、[3H]-Kainate、[3H]-DCKA(5,7-二氯犬尿喹啉酸)或[3H]-MDL 105,510的竞争性排斥来证明,其中确定50%竞争性排斥所需要的浓度(IC50)。
为了确定对AMPA受体的结合亲和性,可例如根据《神经化学杂志》(J.Neurochem.)38,173-178(1981)由Honore T.、Lauridsen J.和KrogsgaardLarsen提出的放射受体分析-试验方案,其中式Ⅰ化合物的IC50值是约0.05至约5μM对Kainate受体的结合亲和性例如可以借助于《神经化学杂志》(J.Neurochem.)26,141-147(1975)中Simon J.R.ContreraJ.F.和Kuhn M.J的放射受体分析-试验方案来测定,其中式Ⅰ化合物的IC50值是约0.5至约5μM。
例如,可在按照Baron M.B、Siegel B.W.等在《欧洲药理学杂志,分子药理学部分》(Eur.J.Pharmacol.,Molec.Pharmacol.Section)206,第149至154页(1991)和Canton T,Doble A.等在《药物药理学杂志》(J.Pharm.Pharmacol.)44,第812至816页(1992)的放射受体分析-试验方案中在大鼠皮质-和大鼠海马膜上确定式Ⅰ化合物在NMDA受体的甘氨酸结合位置上的结合能力。在该试验方案中式Ⅰ化合物的IC50值在约0.005至约5μM范围中。
基于这种特性,式工化合物具有突出的抗惊厥性能,这点可以体内例如在小鼠身上借助于其突出的抗通过电休克或米特腊唑引起的惊厥的保护作用来确定,其中例如可引用根据Schmutz等在《闹宁-斯米德伯格药理学文献》(Naunyn-Schmiedebergs Arch.Pharmacol.)342,61-66(1990)中确立的电休克-小鼠模型或米特腊唑导致的惊厥的小鼠模型。
因此,式Ⅰ化合物和其药物学上可使用的盐非常适合于预防和治疗对兴奋性氨基酸受体的阻断,特别是对一种或多种上述兴奋性氨基酸受体的亚型的阻断有反应的病理学状况,例如预防和治疗神经变性性疾病,如中风、低血糖、缺氧症或脑麻痹现象引起的神经变性性疾病;缺血性脑疾病,如大脑缺血症、在心脏外科手术或心搏停止时的大脑缺血症;围产期Aphyxie、癫痫发作、亨廷顿氏舞蹈病、阿耳茨海默氏和帕金森氏病、扬格氏综合症(amyotroper Lateralsklerose)、脊髓和脑创伤以及神经毒素引起的中毒性现象或者成瘾药滥用,以及眼的缺血性疾病,血管和肌肉痉挛如偏头痛或局部或全身痉挛状态,惊厥如癫痫,以及焦虑和疼痛状态如三叉神经痛。

本发明尤其涉及实施例中提及的式Ⅰ化合物和其盐、制备方法以及包含它们的药物学制剂和其作为药物活性物质的用途。
式Ⅰ化合物制备方法的特征在于:
从式Ⅱ化合物中裂解掉羟基保护基团RC和RD以及任选地存在的羟基保护基团RA和任选地存在的氨基保护基团RB,并且任选地在每种情况下将获得的化合物转化为另一式Ⅰ化合物,将根据该方法获得的异构体混合物拆分为各组分并且在每种情况下分离出优选的异构体和/或将根据该方法获得的游离化合物转化为盐或者将根据该方法获得的盐转化为相应的游离化合物,在式Ⅱ中,RA是氢或羟基保护基团,RB是基团R2或氨基保护基团以及基团RC和RD相同或不同地表示羟基保护基团,R1、X、R2、alk、R3、R4和R5具有上述含义,
羟基保护基团RA例如是用于膦酰基中间保护的常规羟基保护基团,特别地是低级烷基,例如甲基、乙基或异丙基,此外取代或未取代的苯基低级烷基,如苄基,以及三低级烷基甲硅烷基,如三甲基甲硅烷基。羟基保护基团RC和/或RD例如是用于内酰胺中间保护的常规羟基保护基团,特别是成醚的基团,如低级烷基,优选甲基。
合适的的氨基保护基团RB例如是用于氨基中间保护的常用保护基团,如从碳酸的半酯衍生出的酰基基团,如低级烷氧基羰基或未取代或取代的苯氧基或苯基低级烷氧基羰基。
上述保护基团RC、RD和如果需要RA和/或RB的裂除按照常规方式例如通过酸处理,如用盐酸如1N至4N盐酸、约20%至约40%的于乙酸中的氢溴酸处理,或者用三低级烷基卤代硅烷如三甲基溴硅烷,或者六低级烷基二硅氮烷如六甲基二硅氮烷处理,随后加入低级链烷醇,如乙醇(其与硅烷组分反应同时释放卤化氢)来进行。另外保护基团的裂除同样可以通过用路易斯酸如三低级烷基卤代硅烷处理来进行,然而其中所必需的反应条件是苛刻的,如温度在约50至约110℃的范围中。
式Ⅱ的原料例如是这样制备的,即在相应的式Ⅲ化合物中以常规方式例如在钯或阮内镍的存在下通过催化氢化反应将硝基还原为氨基,在酸性条件下,例如在盐酸的存在下,用草酸将所获得的亚苯基-1,2-二胺缩合为相应的式Ⅳ的喹喔啉二酮,通过与能引入卤素Hal的卤化剂例如磷酰氯反应将其转化为相应的式Ⅴ的2,3-二卤代喹喔啉其中以常规的方式例如通过与碱金属的低级链烷醇盐如甲醇钠反应用保护的羟基-ORC或-ORD,如低级烷氧基,特别是甲氧基代替基团Hal,在偶氮-异丁腈或者过氧化二苯甲酰的存在下,用可引入卤素Hal的卤化剂如N-溴琥珀酰亚胺将所获得的式Ⅵ的化合物在侧链上卤化而转化为相应的式Ⅶ化合物并且该化合物通过与叠氮化物如叠氮化钠反应,并随后还原例如通过用二苯基膦和水处理被转化为相应的式Ⅷ的氨基化合物,该化合物或者与结构式为H-X=0(Ⅸ)羰基化合物并接着在碱如三低级烷基胺的存在下与三低级烷基甲硅烷基醚如三甲基甲硅烷基醚、式Ⅹ的化合物缩合或者在氰基硼氢钠的存在下直接与式Ⅺ的化合物缩合。该方案特别适合于制备式Ⅰ的化合物,其中X表示二价脂族、环脂族脂族、芳脂族、杂芳基脂族基团。
在适合于制备其中Ⅹ是低级烷叉,特别是亚甲基的式Ⅰ化合物的方法中,可有利地改变该方案,使式Ⅹ的胺与甲醛或者提供甲醛的试剂反应生成相应的Ⅻ的三嗪并且该化合物例如在碱如三低级烷基胺的存在下与三低级烷基甲硅烷基醚,如三甲基甲硅烷基醚、式Ⅹ的化合物反应。
为了制备其中X在相对氨基的α位上携带氧代基的式Ⅱ化合物,宜在水结合试剂如碳化二亚胺如N-(二甲基氨基丙基)-N’-乙基-碳化二亚胺-盐酸盐的存在下使胺化合物Ⅷ与相应的式ⅩⅢ的羧酸化合物反应或者在碱性缩合剂的存在下与其反应性的衍生物如酰基卤或反应性的酯反应。
本发明的方法获得的化合物可以以常规的方式转化为其它的式Ⅰ化合物。
所以,可以常规方式,例如如果需要在常规碱性缩合剂的存在下,通过与低级烷基化剂如低级烷基卤或反应性的低级链烷酸衍生物如低级链烷酰氯反应在其中R2是氢的式Ⅰ化合物中引入脂族或芳脂族基团,如低级烷基、低级链烯基或低级链烷酰基。
此外,可以常规方式使含酯化或酰胺化羧基的式Ⅰ化合物水解为相应的羧酸,或者以常规方式将含游离羧基的式Ⅰ化合物酯化或酰胺化。
另外,可在所获得的式Ⅰ化合物中,以常规方式将氰基转化为氨基甲酰基。
可以以本身已知的方式将获得的盐转化为游离化合物,例如通过用碱如碱金属的氢氧化物、金属的碳酸盐或金属的碳酸氢盐或者其它开始提及的成盐的碱处理或者用酸,例如无机酸如氢氯酸或者其它上面提及的成盐的酸处理。
可以以本身已知的方式将获得的盐转化为其它盐,对于酸加成盐,例如通过用合适的金属盐如钠盐、钡盐或银盐,其它的酸在合适溶剂(形成的无机盐不溶于该溶剂)中处理,并因此从反应平衡中析出,对于碱式盐,可通过释放游离酸并重新成盐。
式Ⅰ化合物,包括其盐在内,同样可以以水合物的形式获得,或者包含用于结晶的溶剂。
由于以游离形式存在的新化合物和以其盐形式存在的新化合物之间存在紧密的关系,所以上面或随后使用的术语“游离化合物和其盐”按照其意义和目的如果需要同样可以理解为相应的盐或游离化合物。
由于所获得的非对映体混合物和外消旋物混合物在物理-化学上的差异,可以以已知的方式将这些组分分离为纯的非对映体和外消旋物,例如通过色谱分离法和/或分级结晶。
此外,可按照已知的方式将所获得的外消旋物拆分为光学对映体,例如通过从旋光溶剂中重结晶出,借助于微生物或者通过所获得的非对映体混合物或外消旋物与旋光助剂反应,例如根据包括在式Ⅰ化合物中的酸性、碱性或官能可改变的基团与旋光酸、碱或旋光醇反应,形成非对映体盐或官能化的衍生物如酯的混合物,从中分离出各非对映体,以常规的方式由该非对映体中可以释放出所希望的对映体。对此适合的碱、酸或醇例如是旋光生物碱,如马钱子碱、辛可宁或番木鳖碱或D-或L-(1-苯基)乙胺、2-甲基哌啶、麻黄碱、苯异丙胺和类似的合成碱,旋光羧酸或磺酸如喹尼酸或D-或L-酒石酸、D-或L-二-邻甲苯酰基酒石酸、D-或L-苹果酸、D-或L-扁桃酸或D-或L-樟脑磺酸,或者旋光醇如冰片或D-或L-(1-苯基)乙醇。
本发明同样涉及该方法的这样的实施方案,据此,以在该方法的某一步骤中作为中间产物获得的化合物为出发点,并且进行其余的步骤或者使用以盐形式存在的原材料或者特别地在反应条件下形成。
新的专门为制备本发明化合物而开发出的原材料,特别是产生开始作为优选说明的式Ⅰ化合物的原材料,其制备方法和作为中间产物的用途同样构成本发明的内容。
