Abstract
本发明涉及具有GSK-3抑制剂活性的嘧啶酮衍生物。本发明还涉及包含该衍生物的药物组合物,及其在治疗某些病症中的应用。
Description
本申请要求于2006年8月23日提交的美国临时申请第60/823,267号的优先权。
技术领域
本发明涉及具有GSK-3抑制剂活性的嘧啶酮衍生物。本发明还涉及包含该衍生物的药物组合物,及其在治疗某些病症中的应用。
背景技术
蛋白激酶调节胞外事件在细胞质和细胞核内的信号,其实际上参与了多种与细胞的存活和死亡有关的事件,包括有丝分裂、分化和细胞凋亡。当激酶并未被错误调节(misregulated),但仍然对疾病持续必不可少时,某些激酶的抑制剂可以在疾病治疗中发挥效用。在这种情况下,激酶活性的抑制将对这些疾病起到治疗或减缓的作用,因而蛋白激酶抑制剂长期以来都是令人感兴趣的药物目标。
糖原合成酶激酶-3(GSK-3)是一种脯氨酸指导的丝氨酸/苏氨酸激酶,已经识别出该酶的两种亚型GSK-3a和GSK-3b,该酶使糖原合成的限速酶——糖原合成酶(GS)——磷酸化。参见,例如Embi等,Eur.J.Biochem.,107,519-527(1980)。GSK-3a和GSK-3b是高度表达的。参见,例如,Woodgett等,EMBO,9,2431-2438(1990)和Loy等,J.PeptideRes.,54,85-91(1999)。除GS之外,已经识别了许多其它GSK-3底物,包括新陈代谢蛋白、信号蛋白和结构蛋白。在通过GSK-3调节的信号蛋白中,值得注意的是许多转录因子,包括激活蛋白环腺苷酸-1;环AMP反应元件结合蛋白(CREB);活化T细胞的核转录因子(NF);热激因子-1;β-连环蛋白;c-Jun;c-Myc;c-Myb和NF-.sub.KB。参见,例如,C.A.Grimes等,Prog.Neurobiol.,65,391-426(2001);H.Eldar-Finkelman,Trends in Molecular Medicine,8,126-132(2002);以及P.Cohen等,Nature,2,1-8,(2001)。
以GSK-3活性为目标在包括下述在内的病症的治疗中具有显著的治疗潜力:所述病症包括阿尔茨海默氏病(A.Castro等,Exp.Opin.Ther.Pat.,10,1519-1527(2000));哮喘(P.J.Barnes,Ann.Rev.Pharmacol.Toxicol.,42,81-98(2002));癌症(Beals等,Science,275,1930-1933(1997),L.Kim等,Curr.Opin.Genet.Dev.,10,508-514(2000),以及Q.Eastman等,Curr.Opin.Cell Biol.,11,233(1999));糖尿病及其相关后遗症,例如,X综合征和肥胖症(S.E.Nikoulina等,Diabetes,51,2190-2198(2002),Orena等,JBC,15765-15772(2000),以及Summers等,J.Biol.Chem.,27417934-17940(1999));脱发(S.E.Millar等,Dev.Biol.,207,133-149(1999)和E.Fuchs等,Dev.Cell,1,13-25(2001));炎症(P.Cohen,Eur.J.Biochem.,268,5001-5010(2001));情绪障碍,例如抑郁症(A.Adnan等,Chem.Rev.,101,2527-2540(2001)和R.S.B.Williams等,Trends Phamacol.Sci.,21,61-64(2000));神经细胞死亡和中风(D.A.E.Cross等,J.Neurochem.,77,94-102(2001)和C.Sasaki等,Neurol.Res.,23,588-592(2001));双极性病症(bipolar disorder)(Klein等,PNAS,93,8455-8459(1996));以及心肌保护(C.Badorff等,J.Clin.Invest.,109,373-381(2002),S.Haq等,J.Cell Biol.,151,117-129(2000),以及H.Tong等,Circulation Res.,90,377-379(2002))。
GSK-3在多种细胞途径中用作负性介导物,包括胰岛素、IGF-I以及控制肌细胞增殖和分化的Wnt信号级联(Glass,Int.J.Biochem.andCell Biol.,37,1974(2005);McManus等,EMBO J.,24,1571(2005);以及Rochat等,Mol.Biol.Cell.,15,4544(2004))。GSK-3的蛋白水平和活性在肌肉萎缩情况下增加,例如在大鼠和人的衰老及固定(immobilization)中(Cosgrove等,Frontiers in Myogenesis,p.71(2006);以及Funai等,Am.J.Physiol.Regul.Integr.Comp.Physiol.,290,R1080(2006);在去神经术诱发的哮喘中和在II型糖尿病和肥胖的受试者中(Frame等,Expert Opin.Ther.Targets,10,429(2006))。通过RNA干扰或通过小分子的GSK-3抑制刺激肌小管形成,并且减少肌细胞培养中和动物模型中的蛋白水解作用(Van der Velden等,Am.J.Physiol.Cell.Physiol.,290,C453-(2006);Li等,Int.J.Biochem.and Cell Biol.,37,2207(2005);Fang等,Endocrinology,146,3141(2005);Evenson等,Int.J.Biochem.Cell.Biol.,37,2226(2005))。因此,GSK-3活性抑制在对源自肌肉质量和功能的降低或与肌肉质量和功能的降低有关的疾病状态或机能障碍的治疗中具有治疗潜力。这种疾病状态或机能障碍包括,例如,青年的遗传性或外伤性神经病学肌肉疾病状态(例如,肌营养不良);源自痼疾的疾病状态(例如,充血性心力衰竭、慢性肾衰竭、癌、中风等);因长期卧床休息导致的急性病;与老年患者的体力活动降低有关的疾病状态;和/或经历了因长期固定和/或卧床休息(例如,髋关节置换术、大型外科手术等)而导致的急性损伤/疾病的疾病状态。

式I或II的化合物可具有光学中心,因此可以以不同的对映异构和非对映异构构型存在。本发明包括这些式I或II的化合物的所有对映异构体、非对映异构体及其它立体异构体,以及外消旋化合物、混合物及其立体异构体的其它混合物。
式I或II的化合物的可药用盐包括其酸加成盐和碱盐。
合适酸加成盐由形成无毒盐的酸来形成。例子包括但不限于乙酸盐、己二酸盐、天冬氨酸盐、苯甲酸盐、苯磺酸盐、碳酸氢盐/碳酸盐、硫酸氢盐/硫酸盐、硼酸盐、右旋樟脑磺酸、柠檬酸盐、环己基氨基磺酸盐、乙二磺酸盐、乙磺酸盐、甲酸盐、富马酸盐、葡庚糖酸盐、葡糖酸盐、葡糖醛酸盐、六氟磷酸盐、海苯酸盐、盐酸盐/氯化物、氢溴酸盐/溴化物、氢碘酸盐/碘化物、羟乙基磺酸盐、乳酸盐、苹果酸盐、马来酸盐、丙二酸盐、扁桃酸盐、甲磺酸盐、甲基硫酸盐、萘酸盐(naphthylate)、2-萘磺酸盐、烟酸盐、硝酸盐、乳清酸盐、草酸盐、棕榈酸盐、双羟萘酸盐、磷酸盐/磷酸氢盐/磷酸二氢盐、焦谷氨酸盐、水杨酸盐、糖酸盐、硬脂酸盐、琥珀酸盐、磺酸盐、锡酸盐、酒石酸盐、甲苯磺酸盐、三氟乙酸盐和昔美酸盐(xinofoate)。
合适的碱盐由形成无毒盐的碱来形成。例子包括但不限于铝盐、精氨酸盐、苄星青霉素G盐、钙盐、胆碱盐、二乙胺盐、二乙醇胺盐、甘氨酸盐、赖氨酸盐、镁盐、葡甲胺盐、乙醇胺盐、钾盐、钠盐、缓血酸胺(tromethamine)盐和锌盐。
也可形成酸和碱的半盐,例如半硫酸盐和半钙盐。
对于这些和其它合适盐的综述,参见Stahl和Wermuth的“Handbookof Pharmaceutical Salts:Properties,Selection,and Use”(Wiley-VCH,2002)。
式I或II的化合物的可药用盐可通过下述方法制备:
(i)将式I或II的化合物与所需的酸或碱反应;
(ii)使用所需的酸或碱来从式I或II的化合物的合适前体上脱去对酸或碱不稳定的保护基,或通过使用所需酸和碱来使合适的环状前体(例如,内酯或内酰胺)开环;
(iii)通过与合适的酸或碱的反应或通过合适的离子交换柱来将式I或II的化合物的一种盐转化为另一种。
成盐反应通常在溶液中进行。得到的盐可以沉淀或通过将溶剂蒸发来回收。所得盐的电离度可在完全电离到几乎不电离之间变化。
本发明的化合物可以以完全无定形到完全结晶的连续固体形态范围的固态存在。术语“无定形”是指其中材料在分子水平上大范围内无序,并且可根据温度而表现出固体或液体的物理性质的状态。通常,这种材料不能给出特有的X射线衍射图案,且其尽管表现出固体性质,但更规范地被描述为液体。当加热时,发生由固体到液体性质的变化,其特征为通常是二级的状态变化(“玻璃化转变”)。术语“结晶”是指其中物质在分子水平上具有规则有序的内部结构并且给出具有确定峰的特有X射线衍射图案的固体状态。这种物质在充分加热时也将显示液体性质,但从固体到液体的变化的特征在于通常为一级的相变(“熔点”)。
本发明的化合物也可以以非溶剂化和溶剂化的形式存在。术语“溶剂合物”在本文中用于描述包含本发明的化合物和一种或多种可药用溶剂分子(例如,乙醇)的分子配合物。当所述溶剂是水时,使用术语“水合物”。
对于有机水合物,一种目前接受的分类系统是定义了隔离位置(isolated site)水合物、通道水合物或金属离子配位水合物的分类系统。参见,例如,Polymorphism in Pharmaceutical Solids;K.R.Morris(H.G.Brittain编,Marcel Dekker,1995)。隔离位置水合物是其中水分子被介于其间的有机分子隔开而不能互相直接接触的水合物。在通道水合物中,水分子位于晶格通道中,在这里它们紧挨着其它水分子。在金属离子配位水合物中,水分子与金属离子键合。
当处于合适条件下时,本发明的化合物也以介晶态(介晶或液晶)存在。介晶态是处于真晶态和真液态(熔体或者溶液)之间的中间状态。因温度变化而导致的介晶现象被称作“热致型”,而因加入第二组分(如水或另一种溶剂)而导致的介晶现象被称作“溶致型”。具有形成溶致介晶相潜在性的化合物被称为“两亲性的”,并且由具有离子极性端基(例如,-COO-Na+、-COO-K+或-SO3 -Na+)或者非离子极性端基(例如,-N-N+(CH3)3)的分子组成。对于更多信息,参见Crystals and the PolarizingMicroscope;N.H.Hartshorne and A.Stuart,第四版(Edward Arnold,1970)。
本发明的化合物包括如上所定义的式I或II的化合物(包括其所有多晶型物和晶相)、如下所定义的其前体药物和异构体(包括光学异构体、几何异构体和互变异构体)、以及同位素标记的式I或II的化合物。
如本文所示,所谓的式I或II的化合物的“前体药物”也在本发明的范围内,并且可通过用本领域技术人员已知用作“前体部分”的某些部分替换式I或II的化合物中存在的合适官能团来制备。参见,例如,H.Bundgaard的Design of Prodrugs(Elsevier,1985)。
根据本发明的前体药物的一些例子包括:
(i)含有羧酸官能团(COOH)的式I或II的化合物,其相应的酯,例如其中式(I)化合物的羧酸官能团的氢被(C1-C8)烷基代替的化合物;
(ii)含有醇官能团(-OH)的式I或II的化合物,其相应的醚,例如其中式I或II的化合物的醇官能团的氢被(C1-C6)烷酰氧基甲基代替的化合物;和
(iii)含有伯氨基或仲氨基官能团(-NH2或-NHR,其中R≠H)的化合物,其相应的酰胺,例如视情况而定其中式I或II的化合物的氨基官能团的一个或两个氢被(C1-C10)烷酰基替代的化合物。
根据前述例子和其它前体药物类型的例子的替换基团的更多例子可在上述参考文献中找到。
含有一个或多个不对称碳原子的式I或II的化合物可以两种或两种以上的立体异构体存在。当式I或II的化合物含有烯基或亚烯基时,几何顺/反(或Z/E)异构体是可能的。当结构异构体可经由低能垒而互相转换时,可发生互变异构化(“互变异构现象”)。在含有例如亚氨基、酮基或肟基的式I或II的化合物中,这可以采取质子互变异构的形式,或者在含有芳香部分的化合物中可采取被称为价键互变异构的形式。由此,单一化合物可显示一种以上的异构现象。
本发明的范围内包括式I或II的化合物的所有立体异构、几何异构和互变异构形式,包括显示一种以上类型的异构现象的化合物及其中一种或多种的混合物。还包括其中抗衡离子具光学活性(例如,d-乳酸盐或l-赖氨酸)或是外消旋体(例如,dl-酒石酸盐或dl-精氨酸)的酸加成盐或碱盐。
顺/反异构体可通过本领域技术人员公知的传统方法来分离,例如,色谱法和分级结晶。
用于制备/分离独立对映异构体的传统方法包括由合适的光学纯前体进行手性合成或者使用例如手性高压液相色谱(HPLC)来拆分外消旋物(或者盐或衍生物的外消旋物)。
或者,外消旋物(或者外消旋前体)可与合适的光学活性化合物反应,例如醇,或者在式I或II的化合物含有酸性或碱性部分的情况下采用碱或酸,例如1-苯乙胺或酒石酸。得到的非对映混合物可通过色谱法和/或分级结晶来分离,且非对映异构物中的一个或两个通过本领域技术人员公知的方式而被转化为相应的纯对映异构体。
本发明的手性化合物(及其手性前体)可使用色谱法(通常为HPLC)在不对称树脂上用由含有0-50%(体积)的异丙醇(通常为2-20%)和2-5%(体积)的烷基胺(通常为0.1%的二乙胺)的烃(通常为庚烷或己烷)构成的流动相而以富集对映异构体的形式获得。将洗脱物浓缩得到富集的混合物。
当任何外消旋物结晶时,可能有两种不同类型的晶体。第一种类型是以上所指的外消旋化合物(真外消旋物),其中产生了一种包含等摩尔量的两种对映异构体的均相晶体形式。第二种类型是外消旋混合物或聚集体,其中产生了等摩尔量的各自包含一种对映异构体的两种晶体形式。
尽管存在于外消旋混合物中的两种晶体形式具有相同的物理特性,它们可具有与真外消旋物不同的物理性质。外消旋混合物可通过本领域技术人员已知的传统方法来分离。参见,例如,Stereochemistryof Organic Compounds;E.L.Eliel and S.H.Wilen(Wiley,1994)。
本发明包括所有可药用的同位素标记的式I或II的化合物,在所述同位素标记的化合物中,一个或多个原子被具有相同原子序数但原子质量或质量数与自然界中占优势地位的原子质量或质量数不同的原子所替代。
适合包含在本发明化合物中的同位素的例子包括但不限于下述元素的同位素:氢,例如2H和3H;碳,例如11C、13C和14C;氯,例如36Cl;氟,例如18F;碘,例如123I和125I;氮,例如13N和15N;氧,例如15O、17O和18O;磷,例如32p;以及硫,例如35S。
某些同位素标记的式I或II的化合物,例如掺入放射性同位素的那些化合物,可用于药物和/或底物组织分配研究。放射性同位素氚(即3H)和碳-14(即14C)因其掺入容易和已有的检测手段而特别适用于此目的。
同位素标记的式I或II的化合物通常可通过本领域技术人员已知的传统方法或通过与所附实施例中描述的那些方法类似的方法而使用合适的同位素标记的试剂替代以前使用的非标记试剂来制备。
根据本发明的可药用溶剂合物包括其中结晶溶剂可被同位素取代,例如D2O、d6-丙酮、d6-DMSO的那些可药用溶剂合物。
本发明的具体实施方式包括在以下实施例中举例说明的化合物及其可药用盐、配合物、溶剂合物、多晶型物、立体异构体、代谢物、前体药物及它们的其它衍生物。
本发明还涉及一种包含有效治疗所述病症或疾病状态的量的式I或II的化合物的药物组合物。
本发明还涉及一种治疗选自下组的病症的方法:阿尔茨海默氏病、癌、糖尿病、X综合征、肥胖症、脱发、炎症、情绪障碍、神经细胞死亡、中风、双极性病症、因肌肉质量和功能丧失而导致的疾病状态、精子活力降低和心脏保护,该方法包括施用有效治疗所述病症的量的式I或II的化合物。
本发明还提供了一种治疗哺乳动物(包括人)的情绪障碍或情绪发作的方法,该方法包括对所述哺乳动物给予有效治疗所述障碍或发作的量的式I或II的化合物。
本发明还提供了一种治疗哺乳动物(包括人)的情绪障碍或情绪发作的方法,该方法包括对所述哺乳动物给予有效抑制PDE10的量的式I或II的化合物。
