Description
技术领域
本发明涉及用作预防和/或治疗由异常GSK3β活性引起的神经变性疾病的药物活性成分的化合物。
背景技术
GSK3β(糖原合酶激酶3β)为脯氨酸取向的丝氨酸,苏氨酸激酶在控制代谢、分化和生存方面起着重要的作用。其起初被认为是能够磷酸化并因此抑制糖原合酶的化学酶。人们后来认识到GSK3β与T型蛋白激酶1(TPK1)相同,即能够使抗原决定基中的T型蛋白磷酸化的化学酶,其中抗原决定基也被发现在阿尔茨海默综合症和几种tauopathies中过磷酸化。
有趣的是,GSK3β的蛋白质激酶B(AKT)磷酸化导致其激酶活性损失,人们已经假设这种抑制可以调节神经营养性因子的一些作用。再者,β-catenin(涉及到细胞生存的蛋白质)的GSK3β磷酸化可以通过与泛激素化有关的蛋白酶体途径导致降解。
由此可见,抑制GSK3β活性可以引起神经营养活性。的确存在着证据,作为GSK3β的非竞争性抑制因子,在有些情况下,通过引发生存因子如Bc1-2和抑制proapoptotic因子如P53和Bax的表达,锂提升了神经元生成水平并增强了神经存活。
最近的研究已经表明,β-淀粉状蛋白增强了GSK3β活性和T型蛋白磷酸化。另外,这种过磷酸化以及β-淀粉状蛋白的神经毒性作用可被氯化锂封阻,以及被GSK3β反义mRNA封阻。这些观察结果强烈地建议GSK3β可能是阿尔茨海默综合症的两个主要病理学过程之间的连接物:异常APP(淀粉状蛋白前体蛋白)处理和T型蛋白过磷酸化。
尽管T型蛋白过磷酸化导致了神经细胞细胞骨架的动摇,但异常GSK3β活性的病理结果似乎不仅仅是由于T型蛋白的病理磷酸化,这是因为正如上文所述,该激酶的过分活性可能通过调节apoptotic和antiapoptotic因子的表达而影响存活情况。另外,结果已经表明,由β-淀粉状蛋白引起的GSK3β活性增加会导致磷酸化,从而抑制丙酮酸盐脱氢酶、产生能量的关键性酶和乙酰胆碱合成。
所有这些实验结果表明GSK3β可以在治疗神经变性疾病以及与阿尔茨海默综合症有关的认知或注意力缺陷及其它急性和慢性神经变性疾病中发现应用。非限定性地,这些包括帕金森综合症、tauopathies(如frontotemporoparietal痴呆症、corticobasal噁化、Pick疾病、进行性核上麻痹症)及其它痴呆症,包括脉管痴呆症、急性中风及其它外伤、脑血管意外(如与年龄有关的黄斑变性)、脑和脊髓创伤、周围神经病、视网膜病和青光眼。
另外,GSK3β可在治疗其它疾病中发现应用,如非胰岛素依赖糖尿病(如II型糖尿病)和肥胖;狂躁抑郁症;精神分裂症;脱发症;癌症,如乳腺癌、非小细胞肺癌、甲状腺癌、T或B-细胞白血病及几种病毒引起的肿瘤。

作为进-步的目的,本发明也涉及制备由上述式(I)表示的嘧啶-4-酮的方法。
例如,这些化合物可通过下述方法制备。
制备方法
由上述式(I)表示的2-[1,2-a]嘧啶-4-酮化合物可根据流程1制备。
流程1
(在上述流程中,R1、R2、X、Y和n的定义与式(I)化合物已经描述的定义相同)。
其中R1如式(I)化合物定义的由式(I)表示的[1,2-a]嘧啶-4-酮可在N,N-二甲基甲酰胺或氯仿中,在普通空气气氛下于0至130℃的适当温度范围下,与碱(如氢化钠、碳酸钠或碳酸钾)反应,然后与式(II)化合物反应,其中R2、Y和n如式(I)化合物定义,L表示离去基团,得到上述式(I)化合物。
优选地,当X表示氢原子时,L表示溴或甲磺酰基,与氢化钠的反应在N,N-二甲基甲酰胺中,于70至130℃的适当温度范围下进行。
优选地,当X表示氧原子时,L表示氯,与氢化钠的反应在氯仿中,于0至70℃的适当温度范围下进行。
式(II)化合物可以市购或根据本领域技术人员公知的方法制备。
式(III)化合物可以通过流程2定义的方法制备。
流程2
(在上述流程中,R1定义与已经描述的定义相同。)
根据该方法,式(IV)3-酮酯可与式(V)化合物2反应。反应可以在普通空气气氛下,于25-100℃的适当温度范围下,在存在碱(如氢化钠、碳酸钠或碳酸钾)条件下,在如乙醇、丙醇或异丙醇的醇溶剂下进行。
式(IV)化合物可以市购或根据本领域技术人员公知的方法合成。
例如,其中R1表示被C1-4烷基、C1-4烷氧基或氢原子任意取代的吡啶基的式(IV)化合物可以通过被C1-4烷基、C1-4烷氧基或氢原子任意取代的烟酸与丙二酸-酯反应制备。反应可以利用本领域技术人员公知的方法进行,例如在20至70℃温度范围下,在如四氢呋喃的溶剂中,在存在偶合剂如1,1′-羰基二-1H-咪唑的条件下进行。
式(V)化合物可以通过Smith和Christensen描述的方法(J.Org.Chem.1955,20,829)合成。
另外,当Y表示氧原子、X表示氢原子和R2表示芳基或杂芳基时,上述式(I)化合物可通过流程3制备。
流程3
(在上述流程中,R1定义与已经描述的定义相同。)
根据该方法,式(III)化合物可以在普通空气气氛下,于70-130℃的适当温度范围下,在如N,N-二甲基甲酰胺的溶剂下,与碱(如氢化钠或碳酸钾)反应,接着加入式(VI)化合物,其中Pg表示保护基团,优选四氢吡喃,L表示离去基团,优选溴化物。脱保护通过利用本领域技术人员公知的方法进行,例如,当保护基团为四氢吡喃时,脱保护反应可在20-70℃的适当温度范围下,在存在于溶剂如甲醇的氯化铵条件下进行,得到式(VII)化合物。如上文定义,式(I)化合物可利用本领域技术人员公知的方法,将式(VII)化合物与式(VIII)化合物反应制得,例如,反应条件为在室温下,在如四氢呋喃溶剂下,以三苯基膦和二乙基偶氮二碳酸酯作为偶联剂。
式(VI)和(VIII)化合物可以市购或根据本领域技术人员公知的方法合成。
在上述反应中,官能团的保护和脱保护有时是必要的。适当的保护基团Pg可根据官能团的类型进行选择,可以应用文献中描述的方法。保护基团以及保护和脱保护方法的实例参见如Protective groupsin Organic Synthesis Greene et al.,2nd Ed.(John Wiley & Sons,Inc.,New York)。

本发明进一步涉及治疗由异常GSK3β活性引起的神经变性疾病及上述疾病的方法,该方法包括对所需哺乳动物有机体给用有效量的式(I)化合物。
作为本发明药物的活性成分,可使用的物质选自由上述式(I)表示的化合物及其生理可接受盐、溶剂化物和水合物。物质本身可以以本发明药物形式给药,但是需要以药物组合物形式给药,该药物组合物包含作为活性成分的上述物质以及一种或多种药物添加剂。作为本发明药物的活性成分,可以组合使用上述两种或多种物质。上述药物组合物可以补充有用于治疗上述疾病的其它药物活性成分。药物组合物的类型没有特别的限定,组合物可以以任何口服或非肠道给药制剂给出。例如,药物组合物可以制成如适于口服给药的药物组合物形式,如颗粒剂、细颗粒剂、粉剂、硬胶囊剂、软胶囊剂、糖浆剂、乳剂、悬浮剂、溶液等,也可以制成适于非肠道给药的药物组合物形式,如适于静内、肌内或皮下给药的注射剂,点滴剂,经皮给药制剂,转化粘液质制剂,经鼻给药滴液,吸入剂,栓剂等。注射剂或点滴剂可以以粉剂形式制得,如冻干制剂,使用前将其溶解在适当的水合介质中,如生理盐水。如图由聚合物涂层的缓释制剂可以直接进行大脑内给药。
用于制备药物组合物的药物添加剂类型、相对与活性成分的药物添加剂的含量比例可以由本领域技术人员适当选择。无机或有机物质或者固体或液体物质均可用作药物添加剂。一般地,掺入的药物添加剂为活性成分重量的1%至90%。
用于固体药物组合物制剂的赋形剂实例包括,如乳糖、蔗糖、淀粉、滑石、纤维素、糊精、高岭土、碳酸钙等。对于适于口服的液体组合物制剂,可以使用常规的惰性稀释剂,如水或植物油。除了惰性稀释剂之外,液体组合物可以包含助剂,如增湿剂、悬浮助剂、甜味剂、芳香剂、着色剂和防腐剂。液体组合物也可装填在由吸收材料(如明胶)制得的胶囊中。用于非肠道给药的组合物制剂,如注射剂、栓剂的溶剂或悬浮介质的实例包括水、丙二醇、聚乙二醇、苯甲醇、油酸乙酯、卵磷脂等。用于栓剂的基础材料实例包括可可脂、乳化可可脂、月桂酸油脂、witepsol。
本发明药物的剂量和给药频率没有特别限定,主要取决于下述条件,如预防和/或治疗的目的、疾病类型、患者的体重或年龄、疾病的严重程度等。一般地,成年人的口服日剂量可以为0.01至1,000mg(活性成分重量),该剂量可以日服一次或者分成几份分几次给药,或者几天给药一次。当药剂用作注射时,成年人的日剂量为0.001至100mg(活性成分重量),优选连续或间歇给药。
