Abstract
式(I)的化合物涉及用于治疗炎症和自身免疫性疾病。
Description
本发明提供作为IRAK抑制剂的式(I)的吲唑基三唑衍生物、以及它们在治疗癌症和与IRAK过度表达有关的其他疾病(例如类风湿关节炎、系统性红斑狼疮或狼疮性肾炎)中的应用。
背景
激酶催化蛋白质、脂类、糖类、核苷类和其他细胞代谢产物的磷酸化,并且在真核细胞生理学的所有方面发挥关键作用。特别是,蛋白激酶和脂类激酶参与响应于细胞外介质或刺激(例如生长因子、细胞因子或趋化因子)来控制细胞的活化、生长、分化和生存的信号转导事件。一般而言,蛋白激酶被分类成两组,优先地磷酸化酪氨酸残基的组以及优先地磷酸化丝氨酸和/或苏氨酸残基的组。
激酶是抗炎药开发的重要治疗靶点(Cohen,2009年.CurrentOpinion in Cell Biology21,1-8),例如涉及适应性免疫应答和天然免疫应答的和谐结合的的激酶。令人特别感兴趣的激酶靶点是IRAK家族的成员。
白细胞介素-1受体相关激酶(IRAK)关键地涉及对控制炎症的细胞内信号转导网络的调节(Ringwood和Li,2008年.Cytokine42,1-7)。IRAK在许多细胞类型中得到表达并且可以介导来自各种细胞受体(包括toll样受体(TLR))的信号。IRAK4被认为是在白细胞介素-1(IL-1)受体和除TLR3外的所有toll样受体(TLR)的下游被活化的最初蛋白激酶,并且通过IRAK1的快速活化和IRAK2的较慢活化而在先天免疫系统中启动信号转导。IRAK1是首先通过对与IL-1I型受体共同免疫沉淀的IL-1依赖性激酶活性的生物化学纯化而确认(Cao等人,1996年.Science271(5252):1128-31)。IRAK2是通过在人表达序列标签(EST)数据库搜索与IRAKI同源的序列而得到确认(Muzio等人,1997年.Science278(5343):1612-5)。IRAK3(也称为IRAKM)是使用对具有通过筛选人植物凝集素活化外周血白细胞(PBL)CDNA库而发现与IRAK1显著同源性的多肽进行编码的小鼠EST序列而得到确认(Wesche等人,1999.J.Biol.Chem.274(27):19403-10)。IRAK4是利用IRAK样序列的数据库搜索和通用cDNA库的PCR而确认(Li等人,2002年.Proc.Natl.Acad.Sci.USA99(8):5567-5572)。
表达IRAK4的催化无活性突变体而不是野生型激酶的小鼠对由若干TLR激动剂所引发腐败性休克完全耐受,并且它们在对IL-1的响应中受损害。由于遗传缺陷而缺乏IRAK4活性的儿童易发生由脓生成菌所引起的复发感染。IRAK-依赖性TLR和IL-1R似乎对于针对一些脓生成菌的儿童免疫力是至关重要的,但在针对成年人大部分感染的保护性免疫中却发挥多余的作用。因此,IRAK4抑制剂可用于治疗成年人的慢性炎症性疾病,并且不使他们对细菌和病毒感染太敏感(Cohen,2009年.CurrentOpinion in Cell Biology21,1-8)。先已开发强效IRAK4抑制剂(Buckley等人,2008年.Bioorg Med ChemLett.18(12):3656-60)。IRAK1对于IRF7的TLR7介导和TLR9介导活化和干扰素-α(IFN-α)的生成是必不可少的,这表明IRAK1抑制剂可用于系统性红斑狼疮(SLE)的治疗。IRAK2在IRAK4的下游被活化并且在促炎性细胞因子生成中发挥作用。因此,IRAK2抑制剂可用于炎症性疾病。

一般而言,根据本发明的式(I)及相关式的化合物可以从容易获得的起始物质制备。如果这种起始物质无法从市场上买到,则可利用标准合成技术制备。一般而言,用于式(I)及相关式的任何单个化合物的合成路径将取决于各分子的具体取代基,此类因子正如本领域普通技术人员所理解的。可采用下文实施例中所描述的以下一般方法和步骤来制备式(I)及相关式的化合物。下面合成路线中所描述的反应条件(例如温度、溶剂、或共试剂)只是作为例子给出而并不是限制性的。应当理解的是,在给出典型的或优选的实验条件(即反应温度、时间、试剂的摩尔数、溶剂等)的情况下,除非另有说明也可以采用其他实验条件。最佳反应条件可视所使用的具体反应剂或溶剂而变化,但这种条件可以由本领域技术人员利用常规的优化步骤来确定。对于所有的保护和脱保护方法,参见Philip J.Kocienski的“保护基(Protecting Groups)”,Georg Thieme Verlag Stuttgart,纽约(1994年)、以及Theodora W.Greene和Peter G.M.Wuts in“有机合成中的保护基(Protective Groups in Organic Synthesis)”,Wiley Interscience,第三版(1999年)。

此外,可以通过用溶剂分解剂或氢解剂进行处理以便从其功能衍生物之一中释放出式(I)的化合物,而获得式(I)及相关式的化合物。
用于溶剂分解或氢解的优选起始物是符合式(I)及相关式但含有相应的经保护的氨基和/或羟基而不是一个或多个游离氨基和/或羟基的化合物,优选具有氨基保护基而不是键合到N原子的H原子的化合物,特别是具有R*-N基(其中R*表示氨基保护基而不是HN基)的化合物,和/或具有羟基保护基而不是羟基的H原子的化合物,例如符合式I但具有-COOR**基(其中R**表示羟基保护基而不是-COOH基)的化合物。
多个相同或不同的经保护氨基和/或羟基也可以存在于起始物的分子中。如果所存在的保护基彼此不同,那么可以选择性地将它们裂解去除。
术语“氨基保护基”表示一般的含义,并且包括适合于保护(阻止)氨基发生化学反应但在该分子的其他部位已发生期望的化学反应后易于去除的基团。典型的这种基团特别是:未取代或取代的酰基、芳基、芳烷氧基甲基或芳烷基。因为在期望的反应(或者反应序列)后去除氨基保护基,所以它们的类型和大小并不重要;然而,优选的是具有1-20个特别是1-8个碳原子的保护基。术语“酰基”应被理解成与本方法有关的最广义的含义。其包含从脂肪族、芳香脂肪族、芳香族或杂环羧酸或者磺酸类衍生的酰基,特别是烷氧基羰基、芳基氧基羰基,特别是芳烷氧基羰基。这种酰基的例子是:烷基酰基(例如乙酰基、丙酰基和丁酰基);芳烷基酰基(例如苯基乙酰基);芳酰基(例如苯甲酰基和甲苯酰基);芳氧基烷酰基,例如POA;烷氧基羰基,例如甲氧基羰基、乙氧基羰基、2,2,2-三氯乙氧基羰基、BOC(叔丁氧基羰基)和2-碘乙氧基羰基;芳烷氧基羰基,例如CBZ(“苄氧羰基”)、4-甲氧基苄氧基羰基和FMOC;芳基磺酰基,例如Mtr。优选的氨基保护基是BOC和Mtr以及CBZ、Fmoc、苄基和乙酰基。

基于所使用的保护基,使用例如强无机酸(例如盐酸、高氯酸或硫酸)、强有机羧酸(例如三氯乙酸、TFA)、或者磺酸(例如苯磺酸或对甲苯磺酸),而从其功能衍生物中释放出式(I)及相关式的化合物。可以存在附加的惰性溶剂,但并非总是必需的。合适的惰性溶剂优选地是:有机溶剂,例如羧酸类(例如乙酸)、醚类(例如四氢呋喃或二氧六环)、酰胺类(例如DMF)、卤代烃(例如二氯甲烷)、以及醇类(例如甲醇、乙醇或异丙醇);以及水。上述溶剂的混合物也是合适的。优选的是不添加另一种溶剂的情况下使用过量的TFA,优选的是以9:1比率的乙酸和70%高氯酸混合物的形式使用高氯酸。裂解的反应温度有利地是在大约0℃和大约50℃之间,优选在15℃和30℃之间(室温)。
例如,可以优选地使用在二氯甲烷中TFA或者使用在二氧六环中的大约3至5N的HCl在15-30℃下而裂解去除BOC、OtBut和Mtr基,并且可以使用二甲胺、二乙胺或哌啶溶解于DMF的大约5至50%溶液在15-30℃下裂解去除FMOC基。
可以用氢解方法去除的保护基(例如CBZ、苄基,或者从其噁二唑衍生物中释放出脒基),例如可以通过在催化剂存在下(例如贵金属催化剂(例如钯)有利地在载体(例如碳)上)用氢气进行处理而裂解去除。这里的合适溶剂是上述溶剂,特别是例如醇类(例如甲醇或乙醇)或者酰胺(例如DMF)。氢解通常是在大约0和100℃之间的温度和大约1和200巴之间的压力下,优选在20-30℃和1-10巴下进行。CBZ基的氢解例如在5至10%甲醇中的Pd/C或者使用在甲醇/DMF中的Pd/C上的甲酸铵(代替氢气)、在20-30℃下成功地进行。
合适惰性溶剂的例子是:烃类,例如己烷、石油醚、苯、甲苯或二甲苯;氯化烃类,例如三氯乙烯、1,2-二氯乙烷、四氯甲烷、三氟甲基苯、三氯甲烷或二氯甲烷;醇类,例如甲醇、乙醇、异丙醇、正丙醇、正丁醇或叔丁醇;醚类,例如二乙醚、二异丙基醚、四氢呋喃(THF)或二氧六环;二醇醚,例如乙二醇单甲基醚或单乙基醚或者乙二醇二甲醚(二甘醇二甲醚);酮类,例如丙酮或丁酮;酰胺类,例如乙酰胺、二甲基乙酰胺、N-甲基吡咯烷酮(NMP)或二甲基甲酰胺(DMF);腈类,例如乙腈;亚砜类,例如二甲基亚砜(DMSO);二硫化碳;羧酸类,例如甲酸或乙酸;硝基化合物,例如硝基甲烷或硝基苯;酯类,例如乙酸乙酯,或者所述溶剂的混合物。
例如,可以使用HCl、H2SO4或使用溶解于水、水/THF、水/THF/乙醇、或者水/二氧六环的LiOH,NaOH或KOH在0和100℃之间的温度下,将酯类水解。
此外,可以有利地在惰性溶剂(例如二氯甲烷或THF)和/或在碱(例如三乙胺或吡啶)存在下,在-60℃和+30℃之间的温度下,以常规方式使用酰基氯或酸酐将游离氨基酰化,或者使用未取代或取代的卤代烷基将游离氨基烷基化。
式(I)及相关式还包括这些化合物的光学活性形式(立体异构体)、对映异构体、外消旋体、非对映异构体以及水合物和溶剂化物。术语“化合物的溶剂化物”表示由于它们的相互吸引力而形成的惰性溶剂分子到化合物上的加合。溶剂化物例如是一或二水合物或者醇化物。
术语“药学上有用的衍生物”表示例如式I化合物的盐以及所谓的前体药物化合物。
术语“前体药物衍生物”表示用例如烷基或酰基、糖类或寡肽修饰的并且在体内被快速裂解而形成活性化合物的式I化合物。根据式I的化合物,优选地“前体药物”是指在体内被快速转化(例如通过在血液中的水解)而形成式(I)的母体化合物的衍生物化合物。T.Higuchi和V.Stella在“Pro-drugs as NovelDelivery Systems”,A.C.S.SymposiumSeries,第14卷,美国化学社(1975)中提供了对前体药物概念的详细描述。可用作含羧基化合物的前体药物的酯类的例子可以发现于“药物设计中的可生物转化载体:原理和应用Bioreversible Carriers in DrugDesign:Theory and Application”第14-21O页,由E.B.Roche编辑,Pergamon Press:纽约(1987)。这些参考文献以及本说明书中的任何其它引述文献意图以参考的方式并入本文中。
这些前体药物衍生物还包括根据本发明的化合物的可生物降解的聚合物衍生物,例如Int.J.Pharm.115,61-67(1995)中所描述。
式(I)及相关式还包括式I化合物的混合物,例如例如采用1:1、1:2、1:3、1:4、1:5、1:10、1:100或1:1000的比率的两种非对映异构体的混合物。
这些混合物特别优选的是立体异构化合物的混合物。
药物制剂可以以单位剂量的形式给药,包括每单位剂量的预定量的活性成分。基于被治疗的疾病状况、给药方法及患者的年龄、体重和条件,这种单位剂量可以包含例如0.5mg至1g、优选1mg至700mg、特别优选5mg至100mg的本发明化合物;或者药物制剂可以以剂量单位的形式给药,所述剂量单位包含每单位剂量预定量的活性成分。优选的剂量单位剂型是包含每日剂量或者部分剂量(如上所述),或者其相应分数的活性成分的剂型。此外,此类型的药物制剂可以利用药学领域所一般所知的方法制备。
药物制剂可以适合于经由任何期望的合适方法来给药,例如通过口腔(包括颊部或舌下)、直肠、鼻腔、局部(包括颊部、舌下或经皮)、阴道或胃肠外(包括皮下、肌内注射、静脉内注射或皮内注射)方法。可以利用药学领域已知的所有方法来备这种制剂,例如将活性成分与赋形剂或辅助剂混合。
适于口服给药的药物制剂可以用单独的剂量单位的形式而给药,例如胶囊或片剂;散剂或颗粒剂;在水性或非水性液体中的溶液剂或混悬剂;可食用泡沫或泡沫食品;或者水包油液体乳剂或油包水液体乳剂。
因此,例如在采用片剂或胶囊的形式而口服给药的情况下,可以将活性成分与口服无毒且药学上可接受的惰性赋形剂(例如乙醇、甘油、水等)混合。通过将该化合物粉碎成合适的细小尺寸并将其与以类似方式粉碎的药用赋形剂(例如可食用碳水化合物,例如淀粉或甘露醇)混合而制备散剂。同样也可存在矫味剂、防腐剂、分散剂和着色剂。
通过以如上所述方式制备粉末混合物再该将粉末混合物填充入成形明胶壳中而制造胶囊。可以在填充操作前,将助流剂和润滑剂(例如高分散硅酸、滑石、硬脂酸镁、硬脂酸钙或固形式的聚乙二醇)添加到粉末混合物中。同样,可以添加崩解剂或增溶剂(例如琼脂、碳酸钙或碳酸钠)以提高服用胶囊后药物的利用度。
另外,如果期望或者需要,可以类似地将合适的粘合剂、润滑剂和崩解剂及着色剂添加到混合物中。合适的粘合剂包括:淀粉、明胶、天然糖类(例如葡萄糖或β-乳糖)、由玉米制成的甜味剂、天然和合成橡胶(例如阿拉伯胶)、西黄蓍胶或海藻酸钠、羧甲基纤维素、聚乙二醇、蜡类等。这些剂型中使用的润滑剂包括:油酸钠、硬脂酸钠、硬脂酸镁、苯甲酸钠、乙酸钠、氯化钠等。崩解剂包括但不限于:淀粉、甲基纤维素、琼脂、膨润土、黄原胶等。例如,通过制备粉末混合物、制粒或将混合物干法压粉,添加润滑剂和崩解剂再将整个混合物压片以得到片剂,而制备片剂。通过将以合适方式粉碎的化合物与稀释剂或基质混合(如上所述),以及任选地与粘合剂(例如羧甲基纤维素、海藻酸盐、明胶或聚乙烯吡咯烷酮)、溶解阻滞剂(例如石蜡)、吸收促进剂(例如季铵盐)、和/或吸收剂(例如膨润土、高岭土或磷酸二钙)混合而制备粉末混合物。可以通过用粘合剂(例如糖浆、淀粉糊、阿拉伯胶或纤维素或聚合物材料的溶液)润湿该粉末混合物、将其挤压经过筛子而在对该粉末混合物进行制粒。作为制粒的替代,可以使粉末混合物通过压片机,形成不均匀形状的团块,然后将其粉碎而形成颗粒。可以通过添加硬脂酸、硬脂酸盐、滑石或矿物油来轮滑颗粒,而防止这些颗粒粘附到片剂铸模上。然后,将经润滑的混合物压片,而获得片剂。也可以将活性成分与自由流动的惰性赋形剂混合,然后在不执行制粒或干法压制步骤的情况下直接压片而获得片剂。可以存在由虫胶密封层、糖或聚合物材料层及光泽蜡层所组成的透明或不透明保护层。可以将着色剂添加到这些包衣中从而能够在不同的剂量单位之间加以区别。
可以以剂量单位的形式制造口服液(例如溶液、糖浆和酏剂),使得给定量的药剂中包含预定量的化合物。可以通过将这些化合物溶解于含有合适矫味剂的水溶液中而制备糖浆,而使用无毒的醇载体而制备酏剂。可以通过将化合物分散于无毒载体中而制作混悬剂。同样,可以添加增溶剂和乳化剂(例如乙氧基化异硬脂醇和聚氧乙烯山梨醇醚)、防腐剂、矫味剂(例如薄荷油或者天然甜味剂或糖精)、或者其他人造甜味剂等。
如果希望,可以将口服给药的剂量单位制剂包封在微胶囊中。也可以如此制备该制剂,使得例如通过将颗粒材料包覆或埋在聚合物、蜡等中,而使得释放延长或延迟。
式(I)及相关式的化合物、以及它们的盐、溶剂化物和生理功能衍生物和其他活性成分,也可以以脂质体传递系统(例如,单层小囊、大单层小囊和多层小囊)的形式给药。可以用各种磷脂(例如胆固醇、硬脂酰胺或磷脂酰胆碱)形成脂质体。
也可以通过使用作为化合物分子所偶联的单独运载体的单克隆抗体来传输式(I)及相关式的化合物及它们的盐、溶剂化物和生理功能衍生物以及其他活性成分。也可以将这些化合物偶联到作为靶向药物载体的可溶性聚合物。这种聚合物可包括:聚乙烯吡咯烷酮、吡喃共聚物、聚羟基丙基-甲基丙烯酰氨基酚、聚羟乙基天冬酰胺酚或聚氧乙烯聚赖氨酸,被棕榈酰基自由基取代。此外,可将这些化合物偶联到一类适合于实现药物受控释放的可生物降解的聚合物(例如聚乳酸、聚ε-己内酯、聚羟基丁酸、聚原酸酯、聚缩醛、聚二羟基吡喃、聚氰基丙烯酸酯、以及水凝胶的交联或两亲性嵌段共聚物。
适合于经皮给药的药物制剂可以以用于缓释的、与接受者皮肤紧密接触的独立膏药形式给药。因此,例如可以利用电离子透入法从膏药中传递活性成分,如Pharmaceutical Research,3(6),318(1986)中以一般术语所描述。
适于局部给药的药物化合物可以配制成软膏、乳膏、混悬剂、洗剂、散剂、溶液、糊剂、凝胶剂、喷雾剂、气雾剂或油剂。
对于眼睛或其他外部组织(例如口腔和皮肤)的治疗,这些制剂优选地作为局部用软膏或乳膏来施用。在软膏的制剂的情况下,可以将活性成分与石蜡或水可混溶的乳膏基质一起使用。可替换地,可以用水包油乳膏基质或油包水基质调配活性成分而获得乳膏。
适合于局部施用于眼睛的药物制剂包括滴眼剂,其中活性成分溶解或悬浮于合适的载体,特别是水性溶剂。
适合于在口腔中局部施用的药物制剂包括:锭剂、软锭剂和漱口水。
适于直肠给药的药物制剂可以以栓剂或灌肠剂的形式给药。
适合于鼻内给药的药物制剂,其中载体物质是固体,包含粒径例如在20-500微米范围内的粗粉,以吸入的方式,即通过从靠近鼻子的含粉末的容器经由鼻道快速吸入来给药。以使用液体作为载体物质的鼻喷雾剂或滴鼻剂形式给药的合适剂型包括:溶解于水或油的活性成分溶液。
适合于吸入给药的药物制剂包含由各种类型具有气溶胶的加压分配器、雾化器或吹药器所产生的细颗粒粉或薄雾。
适合于阴道给药的药物制剂可以作为阴道栓剂、棉塞、乳膏、凝胶剂、糊剂、泡沫、或喷雾剂给药。
适合于胃肠外给药的药物制剂包括水性和非水性灭菌注射溶液,其中包含抗氧化剂、缓冲液、抑菌剂和溶质,利用该溶质使制剂与接受者的血液等渗;以及水性和非水性灭菌悬浮剂,该悬浮剂可包含悬浮介质和增稠剂。这些制剂可以在单剂量或多剂量容器中给药,例如密封安瓿瓶和玻璃小瓶,并且以冷冻干燥(冻干)状态保存,以便仅需要在即将使用前添加无菌液体载体(例如注射用水)。
根据处方制备的注射溶液和悬浮剂,可以由灭菌粉末、颗粒剂和片剂制成。
当然,除了上述具体描述的成分外,这些制剂也可包含关于具体类型制剂在本领域中常用的其它试剂;因此,例如适于口服给药的制剂可包含矫味剂。
治疗有效量的式(I)及相关式的化合物以及其他活性成分取决于一些因素,包括例如动物的年龄和体重,需要治疗的准确疾病状态、及其严重程度、制剂的性质和给药的方法,并且最终由治疗医生或兽医决定。然而,化合物的有效量通常在0.1至100mg/kg接受者(哺乳动物)体重/天的范围内,特别是通常在1至10mg/kg体重/天的范围内。因此,体重70kg的成年哺乳动物每天的实际剂量通常在70和700mg之间,其中此量可以采用单独剂量/天、或者通常以一系列部分剂量(例如,2、3、4、5或6次)/天的形式给药,因此总的日剂量是相同的。可以作为化合物本身有效量的分数,来确定其生理功能衍生物的盐或溶剂化物的有效量。

由总部位于Bagnols/Cèze法国的CysBio International公司所提供的人IL8试剂盒,能够对细胞培养上清液中的IL-8进行定量测定。
分别用铕穴状化合物和XL665标记抗细胞因子-IL8抗体。当结合到IL-8分子时,这两种抗体非常接近,从而发生FRET(荧光共振能量转移)。此FRET与IL-8浓度成比例地增加,并且可转变成IL8pg的量。
在第1天将THP-1细胞以30000细胞/孔的密度接种在使用RPMI1640的384孔培养板中。将化合物4x/2%DMSO(浓度范围为20μM至1nM)和IL1β4×以100ng/ml的浓度添加到细胞中,于7℃下在5%CO2中保温培养一夜。在第2天通过按照供应商指导将10μl上清液与10μl铕穴状化合物和XL665的复合溶液(v:v)加以混合,而进行IL-8分泌的测量。
在30℃下保温培养3小时后,用BMG Pherasta读数器或等效物测量HTRF(均相时间分辨荧光)信号。
将结果总结于下面的表2中:
*:1μM<IC50<5μM
**:0.1μM<IC50<1μM
