相关技术描述
系统性红斑狼疮(SLE)和狼疮肾炎是以炎症和组织损伤为特征的自身免疫疾病。例如,SLE可以对皮肤、肝脏、肾脏、关节、肺和中枢神经系统造成损伤。SLE患者可经历全身症状,例如极度疲劳、关节疼痛和肿胀、不明原因发热、皮疹、肾功能障碍。因为在患者中涉及的器官不同,因此症状可多样化。SLE是主要发于年轻女性的疾病,发作高峰为15-40岁,并且在女性中的患病率比男性高约10倍。
目前对SLE的治疗通常涉及免疫调节药物,例如贝利单抗(belimumab)、羟氯喹、强的松(prednisone)和环磷酰胺。所有这些药物可具有剂量限制性副作用,并且许多患者仍然患有难以控制的疾病。

发明详述
I.TLR和狼疮
哺乳动物Toll样受体(TLR)除了起到能够检测外源性(“非自身”)病原体相关分子模式(PAMP-即通过TLR4检测细菌LPS)的先天免疫受体的作用以外,它们还能够识别宿主组织损伤或应激反应后释放的内源性刺激物(DAMP)。Kono,H.和K.L.Rock,How dying cellsalert the immune system to danger.Nat Rev Immunol,2008.8(4):p.279-89。在最近的十年中,已经出现了对内源性(“自身”)危险相关分子模式(DAMP)的TLR活化与自身免疫紊乱的病因学之间的关联的理解。具体地,TLR7可以通过来源于哺乳动物源和病毒源的单链RNA(ssRNA)来活化,而TLR9可以通过来源于哺乳动物源、病毒源和细菌源的DNA来活化。
狼疮的特征在于针对双链DNA(dsDNA)本身和相关的蛋白质(组蛋白)的自身抗体反应性,以及针对诸如Ro、La、Smith(Sm)和U1snRNP的RNA相关蛋白质的宽阵列的自身抗体反应性。Kirou,K.A.等人,Activation of the interferon-alpha pathway identifies asubgroup of systemic lupus erythematosus patients with distinct serologicfeatures and active disease.Arthritis Rheum,2005.52(5):p.1491-503。显示与疾病严重程度直接相关的狼疮的第二种常见标志为:在狼疮患者的PBMC(所谓的1型IFN基因标签)中1型干扰素(IFN)(特别是IFNα)的异常表达以及多组IFNα调节基因的相应提高。Kirou,K.A.等人,与前述相同。血液中IFN主要来源于称作浆细胞样树突状细胞(pDC)的特化的免疫细胞,其组成型表达TLR7和TLR9。
当许多研究小组共同证明了从狼疮患者中而不是从健康供体中分离的抗体复合物能够以TLR7/9依赖性和RNA/DNA依赖性的方式驱动pDC产生IFN时,推测了这两种疾病特性、自身抗体以及IFN水平之间的因果关系。Means,T.K.等人,Human lupus autoantibody-DNA complexes activate DCs throμgh cooperation of CD32 and TLR9.J ClinInvest,2005.115(2):407-17页;Vollmer,J.等人,Immune stimulation mediated byautoantigen binding sites within small nuclear RNAs involves Toll-likereceptors 7 and 8.J Exp Med,2005.202(11):1575-85页;Savarese,E.等人,U1 smallnuclear ribonucleoprotein immune complexes induce type I interferon inplasmacytoid dendritic cells throμgh TLR7.Blood,2006.107(8):3229-34页。此外,IFN刺激TLR7/9在B细胞上的表达增加,由此增强自身反应B细胞分化成产生抗体的浆细胞的TLR/BCR(B细胞受体)活化。Banchereau,J.和V.Pascual,Type I interferon insystemic lupus erythematosus and other autoimmune diseases.Immunity,2006.25(3):383-92页。以这种方式,包含核酸TLR7/9配体的自身抗体复合物的水平驱动促炎性循环和狼疮疾病发展。我们认为有可能TLR7/8的药理学拮抗将通过中断这种促炎性循环、降低IFN水平以及抑制由pDC和B细胞介导的自身免疫疾病过程,从而对狼疮患者提供治疗益处。
几种其它证据表明TLR7在人狼疮病因学中的作用,并且支持了TLR受体是疾病干预的有效目标的观点。已经鉴定了在TLR7的3’UTR中的特异性多态性,并且显示出与TLR7表达提高和IFN基因标签增强两者相关。Shen,N.等人,Sex-specific association of X-linked Toll-like receptor 7(TLR7)with male systemic lupus erythematosus.ProcNatl Acad Sci U S A,2010.107(36):15838-43页。Deng,Y.等人,MicroRNA-3148modulates allelic expression of toll-like receptor 7 variant associated withsystemic lupus erythematosus.PLOS Genetics,2013.e1003336。此外,狼疮护理标准(SOC)抗疟药物(例如氯喹)破坏内体TLR7/9信号传导并抑制由ssRNA-核糖核蛋白复合物或狼疮患者血清诱导的PBMC和/或pDC IFNalpha的产生。此外,骨髓DC和单核细胞在自身RNA/TLR8信号传导后产生IL-12p40、TNFα和IL-6,表明除了TLR7驱动pDC产生IFN的作用以外,TLR8依赖性促炎症因子对人狼疮病因学存在额外的作用。Vollmer,与前述相同;Gorden,K.B.等人,Synthetic TLR agonists reveal functional differences between humanTLR7 and TLR8.J Immunol,2005.174(3):1259-68页。
小鼠模型证明在狼疮中也存在TLR的作用。公开的研究已经共同证明,单TLR7基因缺失或双TLR7/9基因缺失或双TLR7/9药理学抑制在四种不同的狼疮模型中降低了疾病的严重程度。Nickerson,K.M.等人,TLR9 regulates TLR7- and MyD88-dependentautoantibody production and disease in a murine model of lupus.J Immunol,2010.184(4):1840-8页;Fairhurst,A.M.等人,Yaa autoimmune phenotypes areconferred by overexpression of TLR7.Eur J Immunol,2008.38(7):1971-8页;Deane,J.A.等人,Control of toll-like receptor 7 expression is essential to restrictautoimmunity and dendritic cell proliferation.Immunity,2007.27(5):801-10页;Savarese,E.等人,Requirement of Toll-like receptor 7 for pristane-inducedproduction of autoantibodies and development of murine lupusnephritis.Arthritis Rheum,2008.58(4):1107-15页。TLR7的转基因过表达仅在正常的抗疾病C57BL/6品系中导致自发性抗-RNA自身反应性和肾炎,这突出了TLR7作为自身免疫的关键性决定因素的作用。Deane,与前述相同。
从安全性角度来看,并没有报道TLR7、TLR8或TLR9单基因缺失型小鼠或者TLR7/8和TLR7/9双基因缺失型小鼠被免疫受损至观测到机会致病菌感染的程度。同样地,认为SOC抗疟药物以预测至少部分抑制TLR7/9信号的剂量长期用于人类中,以控制狼疮疾病发作是非常安全和有效的。Lafyatis,R.,M.York和A.Marshak-Rothstein,Antimalarial agents:closing the gate on Toll-like receptors?Arthritis Rheum,2006.54(10):3068-70页;Costedoat-Chalumeau,N.等人,Low blood concentration of hydroxychloroquineis a marker for and predictor of disease exacerbations in patients withsystemic lupus erythematosus.Arthritis Rheum,2006.54(10):3284-90页。事实上,除了儿童期及较小范围的成人期对革兰氏阳性细菌感染的敏感性增加外,然而具有高度受损的TLR和IL-1R信号传导途径(MyD88缺失或IRAK-4缺失)的人类仍然是健康的并且维持了足够的宿主防御机制。Casanova,J.L.,L.Abel和L.Quintana-Murci,Human TLRs and IL-1Rsin Host Defense:Natural Insights from Evolutionary,Epidemiological,andClinical Genetics.Annu Rev Immunol,2010。
基于此信息和其它信息,我们认为,在小鼠临床前SLE模型的情况中尤其充分证实TLR7是靶标。基因性人体研究和功能性人体研究两者支持以下假设:TLR7和/或TLR8途径的拮抗将对狼疮患者提供治疗益处。此外,小鼠TLR基因缺失研究和人类中抗疟药物的长期使用表明可以在未显著损害宿主防御的情况下进行药理学的TLR7、TLR8和/或TLR9抑制。
因此可以期望,抑制TLR7、TLR8或者TLR7和TLR8两者的化合物用作对SLE或狼疮肾炎的治疗剂或预防剂。
我们已经发现抑制TLR 7和/或TLR 8的化合物,并且因此期望对SLE或狼疮肾炎具有预防或治疗性效果。本文描述了本公开内容的化合物和方法。

一般合成方法:

方案1
利用中间体3来制备至少一个实例,可以根据方案1中所描述的路线来制备中间体3。用盐酸羟胺处理商购的5-溴喹啉-8-甲醛1(Frédérieric de Montigny,GillesArgouarch,Claude Lapinte,“New Route to Unsymmetrical 9,10-DisubstitutedEthynylanthracene Derivatives,”Synthesis,2006,293-298.)以提供肟2。随后在催化量的乙酸铜存在下将2转化为相应的腈3以提供本发明的关键中间体中的一种。使用以下详述的适当条件,通过用适当的芳香族化合物、杂芳香族化合物和饱和的杂环化合物,例如哌啶、哌嗪和吗啉,来取代5-溴喹啉-8-甲醛的5-位,使中间体3用于产生本发明的化合物。
在方案2中示出了产生关键中间体3的替代方法,其中用乙酸钠代替合成中第一步的三乙胺。
方案2
在方案3中显示了用于本发明的另一组实例化合物的方法。由适当取代的、商购的吡啶48起始,对游离胺进行保护以提供49,此后使吡啶氮活化以形成50。使用硼氢化物或其它还原剂对吡啶盐还原,提供不饱和的哌啶51,然后在钯催化剂存在下使用氢通过另外的还原条件得到二取代哌啶,为外消旋混合物或52和53。可以通过使用一当量的手性酸(例如(2R,3R)-2,3-二((4-甲氧基苯甲酰基)氧基)琥珀酸)形成非对映体盐的混合物,其中所需的非对映体盐从溶液中结晶出来,从而对所需的对映体进行拆分。对所得的晶体进行收集、重结晶和脱盐,使得获得高度对映体过量的所需对映体53。然后使用适当的偶联剂使53与5-溴喹啉3偶合以提供Boc保护的54,其容易去保护成为实例55或ER-888840。可以通过使胺55经受亚硝酸钠而容易产生醇类似物56。
方案3
如方案4和方案5所示,可以使用54或55作为关键中间体制备其它实例化合物。可以通过用强碱使酰胺质子进行去质子化,然后添加适当活化的烷化剂而使54烷基化。可以通过还原胺化方法使55烷基化以提供由一般结构57所描述的实例。还可以在适当取代的烷基、芳基、包含适当的离去基团(LG)的基团存在下,通过使用适当的碱使55烷基化,以提供具有如方案4所描述的一般结构57和58的单取代实例和二取代实例的混合物。
方案4
使用活化的酸或使用各种酰胺或肽偶联剂使55酰化以提供如方案5所描述的一般结构59的酰胺。在碱性条件下使59烷基化以提供在一般结构60中所描述的实例。同样地,可以使用本领域的技术人员所熟悉的条件使用活化的烷基磺酰基试剂或芳基磺酰基试剂获得55的磺酰胺,以形成由一般结构61所描述的实例。

一般筛选测定和药理学策略
为了鉴定有效的和选择性的TLR7/8化合物,故对全部人TLR4、TLR7和TLR9报告物系的基于细胞的组进行初始筛选(更多细节参见“材料与方法”)。在原代人PBMC测定中,还测试了对TLR7有效和选择性的至少一种化合物对TLR8的活性(见以下表2)和对TLR7/8的效能(更多细节参见“材料与方法”)。将某些化合物推进入短期体内(STIV)测定以测定对小鼠TLR7的剂量依赖性活性和作用持续时间(更多细节参见“材料与方法”)。然后评估所选择的化合物对以下小鼠狼疮疾病模型BXSB-Yaa、NZBxNZW和Pristane:DBA/1中的一种或多种的影响。
当在细胞系或原代细胞上表达的这些受体受到合成的小分子(CL097,R848)或核酸(RNA)配体刺激时,本文中的实施方案报道的许多化合物显示了对人TLR7和小鼠TLR7及人TLR8的纳摩尔效能。相反地,本文的实施方案中所报道的大多数化合物对TLR9途径是无活性的。
目前,狼疮SOC药物包括诸如氯喹和羟氯喹(HCQ)的抗疟药物,其已经显示可在体内抑制TLR7/9活性。这可以至少部分地解释这些药物在控制狼疮突发中的有效性。然而,本公开内容的实施方案已经显示出提供更显著有效的抑制。这通过以下表1中显示的结果得以证实。
表1.化合物ER-888840相对于羟氯喹(Plaquenil)的效能和选择性。
表2.在HEK-293测定形式中所选化合物对人TLR8的效能(更多细节参见“材料与方法”)。
短期体内(STIV)测定:为了在体内评估化合物对于小鼠TLR7的效能,利用了短期体内(STIV)测定。简而言之,将化合物口服给药于小鼠,然后小鼠在各个时间点皮下注射激动剂R848以刺激TLR7。然后在R848刺激之后,通过ELISA检测了血浆IL-6水平以评估化合物效能和作用持续时间。重要的是,利用TLR7缺失的小鼠,在用R848进行体外或体内刺激之后,细胞因子的产生显示出完全为TLR7依赖性的。因此,可以确信化合物在STIV测定中的活性归因于对TLR7途径的调节。在以下表3中示出了一组化合物的STIV测定效能的汇总。
表3.所选化合物的短期体内(STIV)测定数据的汇总。
小鼠狼疮疾病模型。选择两种不同的狼疮疾病模型(NZB/W和姥鲛烷)用于化合物POC评估,因为(1)NZB/W品系发展为具有多基因病因学的自发性疾病,显示出人狼疮的许多标志,例如DNA相关的自身反应性、蛋白尿和免疫复合物介导的肾炎,以及(2)已经报道了对于两种疾病模型的阳性TLR7和/或TLR9靶标确认结果。
在SLE疾病模型中对于ER-888840的关键发现如下(参见图6和图7):
1)ER-888840在姥鲛烷模型中抑制多种自身抗体特异性。ER-888840还剂量依赖性地显著降低了干扰素调节的基因在姥鲛烷诱导的患病动物中的表达,正如在干扰素评分中所体现的。
结果汇总:这些数据显示了所述化合物对在人狼疮的重要方面中所涉及的过程的调节作用。包含核酸的免疫复合物可以通过树突状细胞驱使1型干扰素产生,并且反映干扰素的存在和干扰素调节基因的后续表达的“干扰素信号”与疾病的严重程度有关。在姥鲛烷模型中ER-888840抑制干扰素驱动的基因的上调。ER-888840限制若干自身抗体特异性的产生。结果表明这些化合物具有控制狼疮症状和在人类患者中进展的潜力。
