Abstract
本发明涉及式(I)化合物,其中R1至R6、m和n如本文所述,及其药学上可接受的盐、对映体或非对映体,以及包括所述化合物的组合物和使用所述化合物的方法。
Description
本发明涉及用于哺乳动物的治疗和/或预防的有机化合物,尤其涉及用于治疗系统性红斑狼疮或狼疮肾炎的TLR7和/或TLR8和/或TLR9的拮抗剂。
技术领域
自身免疫性结缔组织病(CTD)包括典型的自身免疫综合征,例如系统性红斑狼疮(SLE)、原发性干燥综合征(pSjS)、混合性结缔组织病(MCTD)、皮肌炎/多发性肌炎(DM/PM)、类风湿关节炎(RA)和系统性硬化症(SSc)。除RA以外,患者没有真正有效、安全的疗法。SLE代表典型的CTD,其发病率为20-150/100,000,并在不同器官引起广泛的炎症和组织损伤,从皮肤和关节的常见症状到肾、肺或心力衰竭。传统上,SLE已经用非特异性抗炎或免疫抑制药物治疗。但是,长期使用免疫抑制药物(例如皮质类固醇)仅部分有效,并伴有不良的毒性和副作用。贝利木单抗是过去50年中唯一获得FDA批准的治疗狼疮的药物,即使其仅对部分SLE患者具有适度且延迟的疗效(Navarra,S.V.等人.Lancet 2011,377,721.)。其他生物制剂,例如抗CD20单克隆抗体(抗特定细胞因子的单克隆抗体或抗特定细胞因子的可溶性受体的单克隆抗体),在大多数临床研究中均失败。因此,需要新型的疗法,其在更大比例的患者组中提供持续的改善,并且对于在许多自身免疫以及自身炎症性疾病中的长期使用而言更安全。
Toll样受体(TLR)是模式识别受体(PRR)的重要家族,其可以在多种免疫细胞中引发广泛的免疫应答。内体TLR7、8和9作为天然的宿主防御传感器,可识别源自病毒、细菌的核酸,具体地,TLR7/8和TLR9分别识别单链RNA(ssRNA)和单链CpG-DNA。然而,TRL7、8、9的异常核酸传感被认为是广泛的自身免疫和自身炎症性疾病的关键节点(Krieg,A.M.等人.Immunol.Rev.2007,220,251.Jiménez-Dalmaroni,M.J.等人.Autoimmun Rev.2016,15,1.Chen,J.Q.,等人.Clinical Reviews in Allergy&Immunology 2016,50,1.)。抗RNA和抗DNA抗体是SLE的公认诊断标志,这些抗体可以将自身RNA和自身DNA传递至内体。尽管自身RNA复合物可以被TLR7和TLR8识别,但是自身DNA复合物可以触发TLR9激活。实际上,在SLE(系统性红斑狼疮)患者中,自身RNA和自身DNA从血液和/或组织中的缺陷清除很明显。据报道,TLR7和TLR9在SLE组织中被上调,并分别与狼疮性肾炎的慢性和活性有关。在SLE患者的B细胞中,TLR7表达与抗RNP抗体的产生相关,而TLR9表达与IL-6和抗dsDNA抗体水平相关。一致地,在狼疮小鼠模型中,抗RNA抗体需要TLR7,抗核小体抗体需要TLR9。另一方面,小鼠中TLR7或人TLR8的过度表达会促进自身免疫和自身炎症。此外,TLR8的激活特别有助于mDC/巨噬细胞的炎症性细胞因子分泌,中性粒细胞释放胞外捕获网,Th17细胞的诱导和Treg细胞的抑制。除了描述的TLR9在促进B细胞自身抗体产生中的作用外,pDC中自身DNA激活TLR9还会导致诱导I型干扰素和其他炎症性细胞因子。考虑到pDC和B细胞中TLR9的这些作用,它们都是自身免疫性疾病发病机理的关键因素,而且在许多自身免疫性疾病患者中大量存在的可轻易激活TLR9的自身DNA复合物,除抑制TLR7和TLR8途径外,它可能在抑制TLR7和TLR8途径的基础上进一步阻断自身DNA介导的TLR9途径。总之,TLR7、8和9途径代表了治疗自身免疫性疾病和自身炎症性疾病的新治疗靶点,针对这些疾病,不存在有效的不含类固醇和无细胞毒性的口服药物,并且从上游就抑制了所有这些途径可能会带来令人满意的治疗效果。因此,我们发明了靶向和抑制TLR7、TLR8和TLR9的口服化合物,用于治疗自身免疫性疾病和自身炎症性疾病。

合成
本发明的化合物可以通过任何常规方法制备。在以下方案和实例中提供了合成这些化合物及其原料的合适方法。除非另有说明,否则所有取代基,特别是R1至R6如上所定义。此外,除非另有明确说明,否则所有反应、反应条件、缩写和符号均具有有机化学领域普通技术人员众所周知的含义。
制备具有式(I)化合物的一般合成路线在以下流程1中显示。
流程1
其中X为卤素或离去基团,例如,OTf或OMs;m为0、1、2或3;n为1、2、3或4;m+n≤4;R7和R8为保护基,例如,R7为Boc,以及R8为苄基;R9为烷基甲硅烷基,例如三甲基甲硅烷基。
可以使用偶联剂(诸如HATU和DIPEA),实现被保护的氨基酸(II)和甲硅烷基胺(III)的酰胺偶联,以得到中间体(IV)。在通过选择性脱保护除去R7之后,可以在还原条件下(诸如LAH的处理)还原所得中间体(V)中的酰胺键,以得到二胺(VI)。可以在典型的脱水条件下通过醛(VII)和二胺(VI)缩合形成的亚胺(VIII)在光-氧化还原条件下环化,该环化由蓝光和Ir型催化剂(诸如[Ir(dtbbpy)(ppy)2][PF6]),以得到三环内酰胺(IX)。当用还原剂(诸如LAH)处理时,内酰胺(IX)可被还原为具有式(X)的化合物,其中R3和R4均为氢原子。可选地,内酰胺(IX)也可以用二甲基钛茂处理,然后通过氢化还原以在R3或R4上安装烷基。具有式(X)的化合物可用作金属催化的偶联条件下(诸如Buchwald-Hartwig胺化、Suzuki偶联、Negishi偶联,Stille偶联或Pd催化的C=O插入)进一步官能化的常用中间体。例如,在Buchwald-Hartwig胺化条件下(参考文献:Acc.Chem.Res.1998,31,805-818;Chem.Rev.2016,116,12564-12649;Topics in Current Chemistry,2002,219,131-209;和其中引用的文献),用催化剂(诸如Ruphos Pd-G2)和碱(Cs2CO3),可以由具有式(X)的化合物生成式(XI)的化合物。在典型条件下(例如,通过在催化量碳载钯上加氢脱除苄基保护基)对R8基团进行选择性脱保护后,可以将所得的具有式(XII)的化合物置于亲核芳族取代条件(例如,在DMSO中在DIEPA存在下与卤化物(XIII)加热)或Buchwald-Hartwig胺化条件(例如在催化剂(诸如Ruphos Pd-G2)和碱(诸如Cs2CO3)存在下与卤化物(XIII)加热,以得到具有式(I)的化合物。在一些实施例中,具有式(XII)的化合物可以包含保护基,例如Boc,将其除去,得到最终的具有式(I)的化合物。
流程2
通过选择性脱保护从式(X)中除去R8后,所得具有式(XIV)的化合物可在碱(诸如DIEPA)存在下通过亲核芳族取代与卤化物(XIII)反应,得到具有式(XV)的化合物。具有式(I)的化合物可通过金属催化的偶联条件从具有式(XV)的化合物获得:在催化剂(诸如Ruphos Pd-G2)和碱(诸如Cs2CO3)存在下进行Buchwald-Hartwig胺化;在钯催化剂(诸如四(三苯基膦)钯(0)或[1,1'-双(二苯基膦基)二茂铁]二氯钯(II))钯存在下,与二氯甲烷和碱(诸如碳酸钾)在溶剂中复合,而与硼酸、硼酸酯或三氟硼酸钾进行Suzuki偶联;用二氯甲烷和碱,例如碳酸钾在溶剂中;在钯(0)催化剂(例如四(三苯基膦)钯(0))存在下,与有机锡试剂进行Stille偶联;或在钯(0)催化剂(例如四(三苯基膦)钯(0)或[1,1'-双(二苯基膦基)二茂铁]二氯钯(II))的存在下与有机锌试剂进行Negishi偶联。在一些实施例中,具有式(XII)的化合物可以包含保护基,例如Boc,将其除去,得到最终的具有式(I)的化合物。
本发明的化合物可以以非对映体或对映体的混合物形式获得,它们可以通过本领域熟知的方法分离,例如(手性)HPLC或SFC。
本发明还涉及制备具有式(I)、(Ia)或(Ib)的化合物的方法,该方法包括以下任何步骤:
a)在碱存在下,式(XII)化合物,
与卤化物(XIII)的取代反应;
b)在催化剂和碱存在下,式(XII)化合物,
与卤化物(XIII)的Buchwald-Hartwig胺化反应;

为了确定具有式(I)或(Ia)或(Ib)的化合物在HEK293-Blue-hTLR-7/8/9细胞测定中的活性,进行了以下测试。
HEK293-Blue-hTLR-7细胞测定:
稳定的HEK293-Blue-hTLR-7细胞系购自InvivoGen(目录号:hkb-htlr7,圣地亚哥,加利福尼亚,美国)。这些细胞最初设计用于通过监测NF-κB的激活来研究人类TLR7的刺激。将SEAP(分泌的胚胎碱性磷酸酶)报告基因置于与五个NF-κB和AP-1结合位点融合的IFN-β最小启动子的控制下。通过用TLR7配体刺激HEK-Blue hTLR7细胞激活NF-κB和AP-1来诱导SEAP。因此,在配体诸如R848(Resiquimod)的刺激下,孵育20小时后,TLR7拮抗剂使报告基因表达下降。使用QUANTI-BlueTM试剂盒(目录号:rep-qb1,Invivogen,圣地亚哥,加利福尼亚,美国)在640nm波长,在碱性磷酸酶存在下会变成紫色或蓝色的检测介质下,测定细胞培养上清液SEAP报告基因的活性。
HEK293-Blue-hTLR7细胞以250,000~450,000细胞/mL的密度以170μL的体积,在96孔板中在含有4.5g/L葡萄糖、50U/mL青霉素、50mg/mL链霉素、100mg/mL Normocin、2mM L-谷氨酰胺、10%(v/v)热灭活的胎牛血清的Dulbecco's Modified Eagle培养基(DMEM)中孵育,其中在1%的最终的DMSO存在下于连续稀释液中添加20μL测试化合物和10μL的20μMR848的以上DMEM溶液,在37℃的CO2培养箱中孵育20小时。然后将每个孔中的20μL上清液与180μL Quanti-blue底物溶液在37℃下孵育2小时,并使用分光光度计在620~655nm处读取吸光度。TLR7激活导致下游NF-κB激活的信号传导途径已被广泛接受,因此对类似的报告基因检测方法进行了修改以评估TLR7拮抗剂。

hERG通道抑制测定是一种高度灵敏的测量,可鉴定表现出与体内心脏毒性相关的hERG抑制作用的化合物。将hERG K+通道克隆到人体内,并在CHO(中国仓鼠卵巢)细胞系中稳定表达。CHOhERG细胞用于膜片钳(电压钳,全细胞)实验。电压模式刺激细胞以激活hERG通道并传导IKhERG电流(hERG通道的快速延迟向外整流钾电流)。细胞稳定几分钟后,以0.1Hz(6bpm)的刺激频率记录IKhERG的振幅和动力学。此后,将测试化合物以增加的浓度加入制剂中。对于每种浓度,都试图达到稳态效果,通常在3-10分钟内达到此效果,此时施加下一个最高浓度。记录每种药物浓度下IKhERG的振幅和动力学,并将其与对照值进行比较(以100%计)(参考:Redfern WS,Carlsson L,Davis AS,Lynch WG,MacKenzie I,Palethorpe S,Siegl PK,Strang I,Sullivan AT,Wallis R,Camm AJ,Hammond TG.2003;Relationshipsbetween preclinical cardiac electrophysiology,clinical QT intervalprolongation and torsade de pointes for a broad range of drugs:evidence for aprovisional safety margin in drug development.Cardiovasc.Res.58:32-45,Sanguinetti MC,Tristani-Firouzi M.2006;hERG potassium channels and cardiacarrhythmia.Nature 440:463-469,Webster R,Leishman D,Walker D.2002;Towards adrug concentration effect relationship for QT prolongation and torsades depointes.Curr.Opin.Drug Discov.Devel.5:116-26).hERG的结果在表3中给出。

3T3体外光毒性测定
光毒性被定义为在皮肤第一次暴露于某些化学物质并随后暴露于光之后引起的毒性反应,或者是类似的在全身性施用化学物质后通过皮肤照射引起的毒性反应。本研究中使用的测定旨在通过使用Balb/c 3T3小鼠成纤维细胞的简单体外细胞毒性测定来检测化学物质的光毒性潜力。该测试的原理是比较在暴露或不暴露于无毒剂量的UVA-光下进行测试时化学物质的细胞毒性。细胞毒性表示为细胞生长速率的剂量依赖性降低,该降低取决于处理后一天对活性染料中性红的吸收。
方法
制备储备溶液和测试物品的剂量
即将开始暴露于细胞之前,称重少量物质并在DMSO中新鲜配制。将该原液或适当的DMSO稀释液加入细胞悬液中,以获得所需的最终浓度。所有溶液通常在Eppendorf瓶盖中制备,使用后丢弃。
参考物质
氯丙嗪(HCL)(Sigma,批次/批号:120M1328V),测试浓度:300μg/mL,溶剂:PBS/3%DMSO
紫外吸收光谱的测量
用Lambda-2光谱光度计(Perkin Elmer)在240nm和400nm之间记录吸收光谱本身或用UV-A或UV-B预照射的吸收光谱。
UV辐射源:对于UV-A:带有滤波器H1的Sol 500
主要光谱: 315-690nm
辐照度: 大约1.67mW/cm2
辐射剂量 大约5J/cm2
对于UV-B:Philips TL 20W/12
主要光谱: 290-320nm
辐照度: 大约0.083mW/cm2
辐射剂量: 大约0.05J/cm2
光毒性的测定
对于该研究,Borenfreund和Puerner的中性红吸收(NRU)分析(Borenfreund,E,Puerner JA.Toxicity determined in vitro by morphological alterations andNeutral Red absorption.Toxicology Lett.1985;24:119-124.)modified according toINVITTOX protocol No 78(ERGATT/FRAME data bank of in vitro techniques intoxicology.INVITTOX PROTOCOL No 78.3T3 NRU Phototoxicity Assay.March 1994)已被调整为检查测试物品可能的光毒性潜力。该测定基于中性红染料向培养的鼠成纤维细胞的溶酶体中的主动吸收。因为已知溶酶体膜是许多光毒性化合物的作用部位,所以该测定法可以提供潜在的光毒性损伤的量度。
制备细胞培养物
在37℃下在6%CO2的潮湿气氛中将鼠成纤维细胞克隆A 31(ATCC编号CCL 163-第108代)在含有sDMEM(Dulbecco’s最少必备培养基,其中添加了10%的小牛血清、2mM L-谷氨酰胺,100单位/ml的青霉素和100μg/ml的链霉素)的175cm2组织培养级烧瓶中培养。在细胞接近汇合之前,通过胰蛋白酶消化将它们从烧瓶中移出。在用于测定之前,在100μl体积的sDMEM中将细胞以1x104个细胞/孔的浓度转移到96孔微量滴定板中,并使其附着24小时。
暴露于测试物品
为了与鼠成纤维细胞一起孵育,将测试物品稀释在PBS/3%DMSO中(详细浓度见结果)。
培养基(Dulbecco's Modified Eagle培养基(DMEM),GlutaMAX(Gibco Ref21885-025),10%胎牛血清(FBS)(Gibco Ref 10270-106),100IU/ml青霉素和100μg/ml链霉素(Gibco Ref 15140-122)从孔中移出,用PBS洗涤鼠成纤维细胞。然后加入100μL含测试物品的PBS/3%DMSO,并将靶细胞在37℃下用6%CO2孵育1小时。
UV暴露
对于每个测试物品,按照表4制备微量滴定板。将“UVA板”暴露于约5J/cm2的UVA光下,将“深色板”置于黑暗中,作为细胞毒性对照。含有盐酸氯丙嗪的板作为阳性对照。UV通量使用UV计量器(Dr.RM21)测量。
UV照射后,将测试物品从孔中取出(用PBS的一个洗涤步骤),并替换为sDMEM。然后将靶细胞在37℃下在6%CO2中孵育过夜。
表4.96孔微量滴定板设置
96孔微量滴定板的制备如下:
每块板含有带有细胞和溶剂但没有测试物品的孔,这些测试物品未与中性红溶液(0%标准品-S1)一起孵育,或用中性红(100%标准品-S2)染色以计算标准细胞活力曲线。标有U01-U08的孔包含不同的测试物品浓度。
中性红吸收
将要使中性红(NR)染色溶液的新鲜制备如下:
·将0.4%的储备水溶液避光并在使用前过滤以除去NR晶体。
·然后在sDMEM中制备1:40稀释的储备溶液,并添加到细胞中。
孵育后,待测孔中装有100μL含有中性红的sDMEM。将靶细胞与NR在37℃下在6%CO2中于孵育3小时。
中性红吸收测量
从靶细胞中去除未掺入的中性红,并用至少100μL PBS洗涤孔。然后加入150μL中性红脱附溶液(1%冰醋酸,50%乙醇水溶液)以定量萃取所掺入的染料。在微量滴定板振荡器上剧烈振荡至少10分钟后,直到从细胞中提取出中性红并形成均匀溶液为止,使用SPECTRAmax PLUS微量滴定板读数器(Molecular Devices)测量所得有色溶液在540nm的吸收。
计算细胞活力
用SOFTmax Pro软件包(Molecular Devices)计算细胞活力。首先根据以下公式使用程序的线性曲线拟合选项,计算两点标准曲线(0%和100%活力):
Y=A+(B×X)
(A=线的y截距;B=线的斜率;
0%细胞活力=含溶剂但无测试物品和中性红的细胞;
100%细胞活力=含溶剂和中性红但无测试物品的细胞;
通过这种方式,计算与浓度增加的测试化学品一起孵育的细胞的活力。氯丙嗪(HCl)作为实验的阳性对照。
IC50值的计算
所有计算均使用SOFTmax Pro分析软件包进行(分子器件-有关详细信息,请参见:
http://www.mbl.edu/jbpc/files/2014/05/SoftMax_Pro_User_Guide.pdf)
计算光毒性的鉴别因子
为了评估光毒性潜力,比较在有和没有UV暴露下确定的IC50值。
因子=IC50(-UV)/IC50(+UV)
为了区分光毒性和非光毒性测试化学品,使用大于5的截断因子(Liebsch M,Spielmann H,Balls M,Brand M,B,Dupuis J,Holzhüter HG,Klecak G,L.Eplattenier H,Lovell W,Maurer T,Moldenhauer F,Moore L,Pape W,PfannenbeckerU,Potthast JM,De Silva O,Steiling W,Willshaw A.First results of the EC/COLIPAValidation Project.In Vitro Phototoxicity Testing.In:In Vitro SkinToxicology:Irritation,Phototoxicity,Sensitization;Vol.10.Alternative Methodsin Toxicology,-Eds.Rougier A,Maibach HI,Goldberg AM;Mary Ann Liebert Publ.:New York,USA 1994,页.243-251).
即使在最高测试浓度下对鼠成纤维细胞也没有细胞毒性的测试物品,但在UV暴露后显示出细胞活力的强烈剂量依赖性下降,也被认为具有光毒性(Spielmann H,Balls M,Dupuis J,Pape WJW,Pechovitch G,Silva DeO,Holzhütter,HG,Clothier R,Desolle P,Gerberick F,Liebsch M,Lowell WW,Maurer T,Pfannenbecker U,Potthast JM,Csato M,Sladowski D,Steiling W,Brantom P.The international EU/COLIPA in vitrophototoxicity validation study:Results of phase II(blind trial).Part 1:The3T3 NRU phototoxicity test.Toxicology in Vitro 1998,12:305-327).
