Abstract

本发明涉及式I所示的吡啶-2,4-和-2,5-二 羟酸二(硝酰基烷基)酰胺。
式中R具有已指定的意义。本发明的化合物可 抑制酵素脯氨酸羟基酶和赖氨酸羟基酶并可相应地 用作纤维抑制剂药和免疫抑制药。

Description

能抑制酵素脯氨酸羟基酶和赖氨酸羟基酶的化合物能通过影响胶原特有的羟化反应对胶原的生物合成产生非常有选择性的抑制。在此过程中,与蛋白质结合的脯氨酸或赖氨酸被酵素脯氨酸羟基酶或者赖氨酸羟基酶羟化。如果对此反应通过抑制剂进行抑制,则生成无功能的次羟基化胶原分子,这种分子只有少量能被细胞排到细胞外间隙中。此外,这种次羟基化了的胶原不能被结合在胶原母体中,而很容易解肮分解。这个效应的结果是,使在细胞外贮存的胶原总量减少了。
众所周知,通过已知的抑制剂如α,α′-联二吡啶对脯氨酸羟基酶的抑制会导致巨噬细胞的Clq-生物合成的抑制〔W.Muller等,欧洲生物化学学会联合会通讯(FHBS Lett.)90(1978),218;免疫生物学155(1978),47〕。通过这种方式导致补体活化(Komplementaktivierung)不能按常规的途径进行。因此脯氨酸羟基酶抑制剂也起免疫抑制药的作用,例如是免疫综合症时。
众所周知,吡啶-2,4-和-2,5-二羧酸可有效抑制酵素脯氨酸羟基酶(K.Majamaa等;欧洲生物化学杂志(Eur.J.Biochem.)138(1984)239-245〕。在细胞培养中,这些化合物的浓度当然只在很高时才起抑制剂作用〔Tschank,G.等;生物化学杂志(Biochem.J.)238(1987)625-633〕。
DE-A3432094说明了在酯烷基部分有1-6个C-原子的吡啶-2,4-和-2,5-二羧酸二酯可作为抑制脯氨酸羟基酶和赖氨酸羟基酶的药剂。
可是此低烷基化的二酯有缺点,即它们在有机体中会过快地分解成酸,并且在细胞中在其作用位置,达不到足够高的浓度。所以,较少作为药剂使用。
DE-A3703959和DE-A3703962一般地说明了能有效抑制动物型胶原生物合成的吡啶-2,4-和-2,5-二羧酸的混合酯/酰胺、较高烷基化的二酯和二酰胺。
其中DE-A3703959还说明了N,N′-双(2-甲氧基乙基)-吡啶-2,4-二羧酸二酰胺和N,N′-双(3-异丙氧基丙基)-吡啶-2,4-二羧酸二酰胺的合成。
在德国专利申请P3826471.4和P3828140.6中提出了制备N,N′-双(2-甲氧基乙基)-吡啶-2,4-二羧酸二酰胺的改进方法。德国专利登记P3924093.2提出了一种新的N,N′-双(烷氧基烷基)-吡啶-2,4-二羧酸二酰胺。
众所周知,不但吡啶-2,4-和-2,5-二羧酸二酰胺〔Hirakata等;J.Pharm.soc.Japan(日本医药协会杂志)77(1957)219和Haring等Helv.37(1954)147,153〕,而且吡啶-2,4和-2,5-二羧酸二酰胺(Itai等;Bl。nation.hyg.Labor.Tokyo(东京国家卫生实验室通报)74(1956)115,117和Shinohara等;Chem.High  Polymers  Japan(日本高聚物化学),15(1958)839〕均可作为结核病用药。
在日本专利JP53/28175(78/28175)中,说明了N,N′-双(2-硝酰基乙基)吡啶-2,4-和-2,5-二羧酸二酰胺是有扩张血管作用的物质。
意外地发现了,化学式Ⅰ所示的吡啶-2,4-和-2,5-二羧酸二(硝酰基烷基)酰胺和生理上可接受的一些盐,有效地抑制动物型脯氨酸羟基酶和赖氨酸羟基酶。

Figure 911002227_IMG9
式中R的意义如上所述。
下面进一步说明式Ⅰ所示化合物的制备以及此化合物所需原料的制备(如果买不到原料的话)。
制备本发明化合物,最简单的方法是:将式(Ⅱ)所示的吡啶衍生物和式(Ⅲ)所示的胺这二个组分以等摩尔数,或以化合物Ⅲ最多约过量5倍进行混合,并在温度为-30到150℃之间,最好在20至100℃之间使反应进行直到结束为止。反应终点例如可通过薄层色谱法测定。此方法的一种方案是使反应在一种合适的溶剂中进行,如在乙醚或二甲氧基乙烷或四氢呋喃,氯化碳氢化合物如二氯甲烷、氯仿、三氯乙烯或四氯化乙烯,苯、甲苯或极性溶剂如二甲基酰胺,丙酮、醇类例如甲醇或乙醇或二甲基亚砜中进行。在这里使用式(Ⅲ)所示的胺可以最多约过量5倍。反应温度在室温和溶剂的沸点之间,温度范围最好在室温和130℃之间。
此反应同样可以经过一种混合酸酐如氯甲酸乙酯或经过一个活性酯如硝基酚酯(Y=ClCH2-COO或NO2-C6H4-O)来实现。有关方法在文献中有说明。
必要时可使反应在碱存在下进行。可考虑加入的碱例如有:碳酸盐或碳酸氢盐如碳酸钠或碳酸钾或碳酸氢钠或碳酸氢钾;或者叔胺如三乙基胺、三丁基胺、乙基二异丙基胺;或杂环胺如N-烷基吗啉、吡啶、喹啉;或二烷基苯胺。
制备式Ⅰ所示的化合物的另一种方法是:将相应的吡啶-2,4-和-2,5-二羧酸(Ⅳ)的羟烷基二酰胺进行硝化。硝化时使相应的羟烷基二酰胺在-20℃至+10℃最好在-10℃至-5℃与浓硝酸混合。反应时间为10-240分钟,最好为20-90分钟。必要时接着将反应产物中和。
在这种情况下产品的分离可通过萃取或色层分离法例如通过硅胶色层分离法来实现。可将分离出的产品进行重结晶,如果需要可使其和合适的酸反应生成生理上可接受的盐,合适的酸例如:无机酸,如氢氯酸和氢溴酸以及硫酸、磷酸、硝酸和高氯酸,或者有机酸如蚁酸、醋酸、丙酸、丁二酸、羟基醋酸、乳酸、苹果酸、酒石酸、柠檬酸、马来酸、富马酸、苯乙酸、苯甲酸、甲磺酸、甲苯磺酸、草酸、4-氨基苯甲酸、萘-1,5-二磺酸或抗坏血酸。
式(Ⅲ)所示的原料化合物如果买不到,则可按文献中已知的方法合成。
为了得到式(Ⅱ)所示的原料化合物,例如可以通过使吡啶-2,4-或-2,5-二羧酸转化或相应的吡啶-2,4-或2,5-二羧酸卤化物最好为氯化物(根据文献中已知的方法),转化最好在催化剂如二甲基甲酰胺的存在下进行。然后使此酰(基)卤或者与一种合适的醇例如对硝基苯甲醇反应成相应的活性酯,或者与低级醇如甲醇或乙醇反应成相应的酯。同样也可首先使吡啶-2,4-或2,5-二羧酸与一种合适的羧酸或羧酸酯如氯蚁酸乙酯反应转化成混合酸酐,然后使此酸酐与胺(Ⅲ)反应成本发明的产品。相应的方法同样在文献中有说明。
式Ⅳ所示的原料化合物,例如可按文献中已知的方法,通过相应的N,N′-双(烷氧基烷基)吡啶-2,4-或者-2,5-二羧酸二酰胺最好点双(甲氧基烷基)二酰胺反应,例如与三溴化硼反应而得到。双-(烷氧基烷基)二酰胺的制备方法是已知的,
例如在DE-A3703959中就有说明。在此处是使一个有反应能力的吡啶二羧酸酰卤如吡啶-二羧酸酰氯和一种烷氧基烷基胺进行反应。
式Ⅰ所示的本发明化合物具有很有价值的药理性能,并且显示出了作为脯氨酸羟基酶和赖氨酸羟基酶的阻化剂和作为纤维抑制剂及免疫抑制剂的特别有效性。
根据这种药理性能,本发明化合物适用于治疗胶原和似胶原物质的新陈代谢障碍以及治疗Clq的生物合成障碍。
因此本发明还涉及式Ⅰ所示的本发明化合物及其在生理上可接受的盐在治疗上述新陈代谢障碍方面的应用。
这些化合物可以单独或者与生理上可接受的助剂或载体物质混合作为药物使用。在这方面,这些药物的使用量为:口服剂量是0.01-25.0毫克/公斤/天,最好是0.01-5.0毫克/公斤/天;或者不经肠胃的剂量是0.001-5毫克/公斤/天,较好是0.001-2.5毫克/公斤/天,最好是0.005-1.0毫克/公斤/天。对重病人可提高剂量。然而在许多情况下小剂量便可。上述数据适用于体重约为75公斤的成年人。
本发明还包括将本发明化合物用于制备治疗或预防上述新陈代谢障碍的药物。
本发明的另一个对象是含有式Ⅰ所示的一种或几种本发明的化合物和/或其在生理上可接受的盐的药剂。
专业人员用自己熟悉的方法制备这种药剂。可将本发明的药理学上有效的化合物(=有效物质)或者本身,或者最好与合适的制药助剂或载体物质混合加工成药片、糖衣药丸、胶囊、栓剂、乳液、悬浮液或者溶液作为药剂使用,药剂中有效物质含量约达95%,合适的含量在10%和75%之间。
适合于所要求的药物配方的助剂和载体物质例如除了溶剂、凝胶生成剂、栓剂基础、药片助剂和其它有效物质载体以外还有抗氧剂、分散剂、乳化剂、去泡剂、矫味剂、防腐剂、有机溶剂和着色剂。
这些有效物质可以口服,可在肠胃以外使用或在直肠中使用。
使这些有效物质与合适的添加剂如载体物质、稳定剂、或惰性稀释剂相混合,并采用一般方法制成合适的提供形式,如药片、糖衣药丸、棒状胶囊、水的悬浮液、醇的悬浮液和油的悬浮液,或水的溶液或油的溶液。
可用作惰性载体物质的例如有:阿拉伯树胶、氧化镁、碳酸镁、磷酸钾、乳糖、葡萄糖、或淀粉,特别是玉米淀粉。在此既可配成干颗粒也可配成湿颗粒。作为油状载体物质或溶剂。例如可考虑采用植物油或动物油,如葵花子油或鱼肝油。
为了皮下或静脉内使用,可按希望用合适的物质如有机溶剂、乳化剂或别的助剂将这些有效物质制成溶液、悬浮液或乳液。可以作为溶剂的例如有:生理食盐水或醇,例如乙醇、丙醇、甘油,此外还有糖溶液如葡萄糖溶液或甘露醇溶液、或者还有由上面提到的不同溶剂制成的混合物。
