Abstract
Description
本申请是分案申请,原案申请日为2015年10月30日,申请号为201580071983.0(国际申请号为PCT/US2015/058193;针对的分案申请号:201711211144.1),发明名称为“作为Rorγt调节剂的三氟甲基醇”。
技术领域
本发明涉及取代的噻唑化合物、其药物组合物和使用方法,所述取代的噻唑化合物为核受体RORγt的调节剂。更具体地,RORγt调节剂可用于预防、治疗或改善RORγt介导的炎性综合征、障碍或疾病。
背景技术
与视黄酸相关的核受体γt(RORγt)是仅在免疫系统的细胞中表达的核受体,并且是驱动Thl7细胞分化的关键转录因子。Th17细胞是CD4+T细胞的亚群,Th17细胞在它们的表面上表达CCR6,以介导它们迁移至炎症部位,并且依赖于IL-23刺激,通过IL-23受体来进行它们的保持和扩增。Th17细胞会产生多种促炎细胞因子,包括IL-17A、IL-17F、IL-21和IL-22(Korn,T.,E.Bettelli等人(2009),“IL-17 and Th17 Cells.”Annu Rev Immunol27:485-517),这些细胞因子刺激组织细胞产生一系列炎性趋化因子、细胞因子和金属蛋白酶,并且促进粒细胞的募集(Kolls,J.K.和A.Linden(2004)“Interleukin-17 familymembers and inflammation.”Immunity 21(4):467-76;Stamp,L.K.,M.J.James等人,(2004),“Interleukin-17:the missing link between T-cell accumulation andeffector cell actions in rheumatoid arthritis”Immunol Cell Biol 82(1):1-9)。Th17细胞已被证明是包括胶原诱导性关节炎(CIA)和实验性自身免疫性脑脊髓炎(EAE)在内的多种自身免疫性炎症模型中的主要致病性群体(Dong,C.(2006).“Diversificationof T-helper-cell lineages:finding the family root of IL-17-producing cells.”Nat Rev Immunol 6(4):329-33;McKenzie,B.S.,R.A.Kastelein等人,(2006),“Understanding the IL-23-IL-17 immune pathway.”Trends Immunol 27(1):17-23)。RORγt缺陷的小鼠表观健康且繁殖正常,但显示出Th17细胞体外分化受损,体内Th17细胞群数量显著降低,并且对EAE敏感性的降低(Ivanov,II,B.S.McKenzie等人,(2006),“Theorphan nuclear receptor RORgammat directs the differentiation program ofproinflammatory IL-17+T helper cells.”Cell 126(6):1121-33)。缺乏IL-23(Th17细胞存活所必需的细胞因子)的小鼠不能产生Th17细胞,并且对于EAE、CIA和炎性肠病(IBD)具有抗性(Cua,D.J.,J.Sherlock等人(2003)“Interleukin-23 rather than interleukin-12 is the critical cytokine for autoimmune inflammation of the brain.”Nature421(6924):744-8;Langrish,C.L.,Y.Chen等人(2005)“IL-23 drives a pathogenic Tcell population that induces autoimmune inflammation.”J Exp Med 201(2):233-40;Yen,D.,J.Cheung等人(2006).“IL-23 is essential for T cell-mediated colitisand promotes inflammation via IL-17 and IL-6.”J Clin Invest 116(5):1310-6)。与上述发现相符,抗IL23特异性单克隆抗体会阻断小鼠疾病模型中银屑病样炎症的发展(Tonel,G.,C.Conrad等人,“Cutting edge:A critical functional role for IL-23 inpsoriasis.”J Immunol 185(10):5688-91)。
在人体中的许多观察结果都支持IL-23/Th17途径在炎性疾病发病机制中的作用。由Th17细胞产生的关键细胞因子IL-17在多种过敏性疾病和自身免疫性疾病中的表达水平升高(Barczyk,A.,W.Pierzchala等人(2003)“Interleukin-17 in sputum correlateswith airway hyperresponsiveness to methacholine.”Respir Med 97(6):726-33;Fujino,S.,A.Andoh等人(2003)“Increased expression of interleukin 17ininflammatory bowel disease.”Gut 52(1):65-70;Lock,C.,G.Hermans等人(2002)“Gene-microarray analysis of multiple sclerosis lesions yields new targetsvalidated in autoimmune encephalomyelitis.”Nat Med 8(5):500-8;Krueger,J.G.,S.Fretzin等人,“IL-17A is essential for cell activation and inflammatory genecircuits in subjects with psoriasis.”J Allergy Clin Immunol 130(1):145-154e9)。此外,人类基因研究显示,Th17细胞表面受体IL-23R和CCR6的基因多态性与对IBD、多发性硬化症(MS)、类风湿性关节炎(RA)和银屑病的易感性具有关联(Gazouli,M.,I.Pachoula等人“NOD2/CARD15,ATG16L1and IL23R gene polymorphisms and childhood-onset of Crohn's disease.”World J Gastroenterol 16(14):1753-8;Nunez,C.,B.Dema等人,(2008)“IL23R:a susceptibility locus for celiac disease and multiplesclerosis?”Genes Immun 9(4):289-93;Bowes,J.和A.Barton,“The genetics ofpsoriatic arthritis:lessons from genome-wide association studies.”Discov Med10(52):177-83;Kochi,Y.,Y.Okada等人,“A regulatory variant in CCR6 isassociated with rheumatoid arthritis susceptibility.”Nat Genet 42(6):515-9)。
Ustekinumab是一种阻断IL-12和IL-23两者的抗p40单克隆抗体,它被批准用于治疗患有中度至重度斑块型银屑病、需接受光疗或全身治疗的成年患者(18岁或以上)。目前对于银屑病,也正在临床开发仅特异性地靶向IL-23的单克隆抗体,以便更加具有选择性地抑制Th17亚群(Garber K.(2011).“Psoriasis:from bed to bench and back”Nat Biotech 29,563–566),进一步揭示了IL-23和RORγt驱动的Th17途径在该疾病中的重要作用。最近的II期临床研究结果为这一假设提供了有力支持,因为抗IL-17受体和抗IL-17治疗性抗体两者都在慢性银屑病患者中表现出高水平的疗效(Papp,K.A.,“Brodalumab,an anti-interleukin-17-receptor antibody for psoriasis.”N Engl J Med 2012 366(13):1181-9;Leonardi,C.,R.Matheson等人,“Anti-interleukin-17 monoclonalantibody ixekizumab in chronic plaque psoriasis.”N Engl J Med 366(13):1190-9)。在RA和葡萄膜炎的早期试验中,抗IL-17抗体也已表现出相关临床反应(Hueber,W.,Patel,D.D.,Dryja,T.,Wright,A.M.,Koroleva,I.,Bruin,G.,Antoni,C.,Draelos,Z.,Gold,M.H.,Durez,P.,Tak,P.P.,Gomez-Reino,J.J.,Foster,C.S.,Kim,R.Y.,Samson,C.M.,Falk,N.S.,Chu,D.S.,Callanan,D.,Nguyen,Q.D.,Rose,K.,Haider,A.,Di Padova,F.(2010)“Effects of AIN457,a fully human antibody to interleukin-17A,onpsoriasis,rheumatoid arthritis,and uveitis.”Sci Transl Med 2,5272)。
以上所有证据均支持将通过调节RORγt活性来抑制Th17途径作为治疗免疫介导的炎性疾病的有效策略。

由于RORγt是RORγ的N-末端同种型,因此已经认识到本发明的化合物即RORγt的调节剂也有可能是RORγ的调节剂。因此,机理描述“RORγt调节剂”也旨在涵盖RORγ调节剂。
当用作RORγt调节剂时,本发明的化合物可以在约0.5mg至约10g的剂量范围内,优选在约0.5mg至约5g之间的剂量范围内的有效量,以单次施用或分开的日剂量施用。所施用的剂量将受诸如给药途径,接受者的健康状况、体重和年龄,治疗频率以及同期治疗和不相关的治疗的存在等因素影响。
对于本领域的技术人员还将显而易见的是,本发明的化合物或其药物组合物的治疗有效剂量将根据期望的效果而变化。因此,本领域技术人员可容易地确定待施用的最佳剂量,并且最佳剂量将随所使用的具体化合物、给药方式、制剂强度和疾病状况的进展而变化。另外,与接受治疗的具体受治疗者相关的因素,包括受治疗者年龄、体重、饮食和给药时间,将导致需要将剂量调整至适当的治疗水平。因此,上述剂量为一般情况的示例。当然,可能会存在其中应使用较高或较低剂量范围的个别情况,并且这类情况也在本发明的范围内。
可以将式I的化合物配制成包含任何已知的药学上可接受的载体的药物组合物。示例性载体包括但不限于任何合适的溶剂、分散介质、包衣、抗菌剂和抗真菌剂以及等渗剂。同样可作为制剂组分的示例性赋形剂包括填充剂、粘合剂、崩解剂和润滑剂。

在任何用于制备本发明的化合物的方法中,可能必需和/或期望保护任何有关分子上的敏感基团或反应性基团。这可通过常规保护基团来实现,如Protective Groups in Organic Chemistry,J.F.W.McOmie,Plenum Press,1973;和T.W.Greene&P.G.M.Wuts,Protective Groups in Organic Synthesis,John Wiley&Sons,1991中所述那些。可使用本领域已知的方法在方便的后续阶段除去保护基团。

一般方案:
本发明中的式I的化合物可根据本领域技术人员已知的一般合成方法合成。下面的反应方案仅意在代表本发明的示例,而绝无意于限制本发明。
本发明的化合物可根据方案1至5制得。式I的化合物的芳基与噻唑环的偶联可通过在钯催化剂的存在下,使用适当的配体、溶剂、添加剂和温度,使溴代-芳基/杂芳基结构单元E-I/II或F-I偶联至噻唑衍生物A-I-V,形成5-芳基/杂芳基取代的噻唑B-I至B-VII来实现(方案1)。噻唑反应物可被酯基团(A-I、A-II、A-IV)、酰胺基团(A-I-III、A-V)或烷基基团(A-IV-V)进行2-和4-取代。
方案1
噻唑衍生物A-I-V的制备示于方案2中。A-I和A-III可通过酰胺键形成和酯水解标准方法,自2-(烷氧基羰基)噻唑-4-甲酸起始制得。另选地,中间体A-I可在适当溶剂和温度下,经历与胺的直接氨解获得A-III。可通过首先将2-羧基-溴-噻唑C-II酰胺偶联,然后羰基化以提供噻唑甲酯A-IIa,或通过由C-I形成叔丁酯C-IV,接着在噻唑环2-位选择性酯水解,并且最终进行酰胺偶联反应提供A-IIb,制得噻唑酯A-II。噻唑衍生物A-IV可在环状缩合步骤中,由1-溴-3-羟基丙-2-酮和2-氨基-2-硫代乙酸烷基酯C-V制备。A-IV酯水解,然后酰胺偶联,提供中间体A-V(方案2)。
方案2
溴代-芳基/杂芳基衍生物E-I/E-II/F-I的制备示于方案3中。1,4-二溴或1-溴-4-碘-芳族化合物可用作金属化反应的反应物,例如用正丁基锂锂化,或使用异丙基氯化镁进行格氏形成。1,4-二溴芳族化合物应具有相同的取代基R1和R2。金属化物质可与三氟乙酸的Weinreb酰胺反应,以形成1-溴-4-三氟乙酰基衍生物D-II。另选地,金属化物质可与六氟丙酮反应,以直接形成三氟丙酮醇E-I,其中R3为CF3基团。三氟甲基醇E-I可通过使D-II与TMSCF3在氟化物源存在下反应或通过与烷基格氏试剂反应来形成。中间体D-II也可通过使1-溴-4-烷氧羰基芳族化合物(其可使用试剂如亚硫酰氯和甲醇,由对应的4-溴苯甲酸(D-III)经由酯化来制备)与TMSCF3在氟化物源存在下反应来形成。另选地,中间体D-II可通过由1-溴-4-甲酰基芳族化合物与TMSCF3在氟化物源存在下反应,然后进行氧化而形成(方案3)。5-溴-2-碘吡啶(D-VI)可用作金属化反应(例如用正丁基-锂锂化)的反应物,并且金属化物质可与三氟乙酸乙酯反应以形成5-溴-2-三氟乙酰基吡啶衍生物D-VII。三氟甲基醇E-II可通过使D-II与TMSCF3在氟化物源存在下反应来形成。1,3-二溴芳基衍生物F-II可经金属化(例如用正丁基锂锂化),随后与三氟乙酸的Weinreb酰胺反应将形成1-溴-3-三氟乙酰基衍生物F-III。三氟甲基醇F-I可通过使F-III与TMSCF3在氟化物源存在下反应或通过与烷基格氏试剂反应来形成。
方案3
获得本发明式B-III化合物的替代合成途径示于方案4中。由钯催化偶联反应产物B-IV、B-I或B-II(如方案1中所示)开始,羟甲基中间体B-IV可氧化成对应的羧酸,其可用于酰胺偶联反应中以获得中间体B-I。B-I和B-II均可通过首先进行酯水解,然后进行酰胺偶联反应,而转变成本发明的化合物B-III。另选地,中间体B-I可在适当溶剂中及温度下与胺直接氨解,以在一个步骤中获得本发明的化合物B-III。在另一个替代途径中,式B-III的化合物可由中间体B-VI经由氧化,接着酰胺偶联而获得(方案4)。

体外生物学数据
是以荧光为基础的测定法,通过测量配体对蛋白质热稳定性的影响来估计配体结合亲和力(Pantoliano,M.W.,Petrella,E.C.,Kwasnoski,J.D.,Lobanov,V.S.,Myslik,J.,Graf,E.,Carver,T.,Asel,E.,Springer,B.A.,Lane,P.和Salemme,F.R.(2001)“High-density miniaturized thermal shift assays as a general strategyfor drug discovery.”J Biomol Screen 6,429-40;以及Matulis,D.,Kranz,J.K.,Salemme,F.R.和Todd,M.J.(2005)“Thermodynamic stability of carbonic anhydrase:measurements of binding affinity and stoichiometry using ThermoFluor.”Biochemistry 44,5258-66)。此方法适用于多种系统,在通过量化平衡结合常数(KD)阐释理论方面非常严格。
实验用于监测蛋白质稳定性随温度稳定升高而发生的改变,其中,配体结合平衡使解折叠转化的中点(Tm)在较高温度处出现。解链温度的偏移(被描述为ΔTm)与配体的浓度和亲和力成比例。可将化合物效力按照单一化合物浓度处的ΔTm值的等级次序比较,或按照由浓度响应曲线估计的KD值的等级次序比较。
就用于测定法的RORγt构建体来说,核苷酸序列的编号基于人RORγt的参考序列,即转录变体2,NCBI登录号:NM_001001523.1(SEQ ID NO:1)。将编码野生型人RORγt配体结合域(RORγt LBD)的第850-1635位核苷酸(SEQ ID NO:2)克隆进pHIS1载体中,即经修饰的pET大肠杆菌(E.coli)表达载体(Accelagen,San Diego),该载体在克隆的插入序列上游含有框内N-末端组氨酸标签和TurboTEV蛋白酶切割位点(ENLYFQG,SEQ ID NO:3)。测定法中使用的RORγt构建体的氨基酸序列以SEQ ID NO:4示出。
实验是使用由Janssen Research and Discovery,L.L.C.收购3-Dimensional Pharmaceuticals,Inc.而拥有的仪器实施的。将1,8-ANS(Invitrogen)用作荧光染料。将蛋白质和化合物溶液分配进黑色的384孔聚丙烯PCR微孔板(Abgene)中,上覆一层硅油(1μL,Fluka,型号DC 200)以防止蒸发。
就所有实验来说,用自动机将印有条形码的测定板装到恒温控制的PCR型热模块上,然后以1℃/min的典型升温速率加热。用光纤提供并经由带通滤光片(380-400nm,截止值>6OD)过滤的紫外光(Hamamatsu LC6)连续照明,测定荧光。使用滤光后检测500±25nm的CCD相机(Sensys,Roper Scientific)测量光强度,同时分别产生全部384个孔的读数,由此检测整块384孔板的荧光发射。收集各温度下的图像,比照温度记录测定板给定区域中像素强度的总和。对照孔盛有RORγt,但无化合物,测定条件如下:
0.065mg/mL RORγt
60μM 1,8-ANS
100mM Hepes,pH 7.0
10mM NaCl
2.5mM GSH
0.002%Tween-20
将标题化合物以预定剂量布置在母板(Greiner Bio-one)中,其中化合物用100%DMSO,以1:2比率,从高浓度10mM逐级稀释到连续的12个列中(第12列是含DMSO但不含化合物的对照孔)。使用Hummingbird毛细管移液器(Digilab)将化合物自动地直接分配到测定板中(1x=46nL)。分配好化合物后,添加缓冲液中的蛋白质和染料,获得3μL的最终测定体积,再加入1μL硅油。
使用下列蛋白质解折叠的热力学参数,按前文所述方法估计结合亲和力(Matulis,D.,Kranz,J.K.,Salemme,F.R.,和Todd,M.J.(2005)“Thermodynamic stabilityof carbonic anhydrase:measurements of binding affinity and stoichiometryusing ”Biochemistry 44,5258-66),参数如下:
参考RORγt Tm:47.8℃
ΔH(Tm)=115kcal/mol
ΔCp(Tm)=3kcal/mol
