Abstract
本发明公开了一种式I所示化合物及其组合物和应用,其中A,X,Y,L,M和W如本文所定义。本发明公开的化合物可以用于治疗与JAK3激酶过度激活或者过度表达相关的疾病如自身免疫性疾病、肺损伤、器官移植排斥疾病。体外实验表明,该系列化合物具有良好的JAK3激酶抑制活性作用,在医药领域具有良好的应用前景。
Description
技术领域
本发明属于医药技术领域,涉及具有一种或多种Janus激酶(JAK)抑制活性的芳杂环化合物,本发明还涉及所述化合物作为活性成分的药物组合物以及其应用。
背景技术
Janus激酶(JAK)是负责转导许多炎症相关细胞因子信号从细胞因子膜受体到STAT转录因子的细胞质酪氨酸蛋白激酶。JAK/STAT信号转导异常与许多疾病有关,参与免疫炎症相关的疾病如器官移植排斥反应、多发性硬化、类风湿性关节炎、I型糖尿病、狼疮、银屑病、哮喘、食物过敏、特应性皮炎和鼻炎、皮疹等;也有报道和实体和血液恶性肿瘤以及骨髓增生障碍(包括肺癌、乳腺癌、慢性自发性骨髓纤维变性、红细胞增多症、特发性血小板增多症等)的发生发展密切相关。
第一代JAK抑制剂对JAK激酶家族亚型展现出广泛的抑制活性,在炎症性疾病、肿瘤、血液疾病中具有良好疗效。然而由于JAK激酶家族广泛介导多种细胞因子的信号传导,其中很多功能与机体正常生理功能密切相关,Pan-JAK抑制剂在临床应用中显现出的副作用包括贫血、中性粒细胞减少症、感染、淋巴细胞减少症、高脂血症等,其中Tofacitinib存在感染和血栓风险,被FDA发出黑框警告,Ruxolitinib也有血小板异常黑框警告。
第二代选择性JAK抑制剂通常主要作用于JAK家族特定亚型,在控制疾病发展的同时,能够降低不良反应事件的发生。目前已经上市的JAK选择性抑制剂包括新基的JAK2抑制剂Fedratinib,艾伯维的JAK1选择性抑制剂upadacitinib和Gilead的JAK1抑制剂Filgotinib。JAK1抑制剂治疗免疫疾病的疗效突出,但仍属于广谱免疫抑制剂,选择性有限,安全性风险较高,已上市的JAK1抑制剂Upadacitinib和Baricitinib均有黑框警告,已上市的JAK2抑制剂Fedratinib也有韦尼克脑病、眼眶炎症反应等严重不良反应。
JAK3主要表达于各造血组织细胞中,包括骨髓细胞、胸腺细胞、NK细胞及活化的B淋巴细胞、T淋巴细胞等,其生理效应仅源于常见的γ细胞因子受体家族的信号转导过程,因此高选择性作用于JAK3激酶可以避免不必要的副作用。因此提高JAK3激酶抑制剂的活性和选择性,能够进一步提高JAK3激酶抑制剂的临床使用效果,相较于目前临床应用的Pan-JAK抑制剂和选择性JAK1、JAK2抑制剂具有显著的临床优势。目前高选择性JAK3抑制剂除了PF-06651600已经进入临床后期开发阶段并获得FDA突破性疗法的认定用于治疗斑秃,其他的JAK3激酶抑制剂仍处于学术研究和临床早期开发阶段。PF-06651600还不可逆地抑制TEC激酶家族(BTK,BMX,ITK,RLK,TEC),PF-06651600对于自身免疫性疾病的治疗效果很大程度上还来源于其对TEC激酶家族的抑制。临床2a期数据表明PF-06651600的治疗期间出现的不良事件是感染、皮肤及皮下组织疾病。同时不少病人出现了血小板减少的症状,这可能与PF-06651600对于TEC激酶家族的抑制作用相关。(Robinson M.F.,Damjanov N.,Stamenkovic B.et al.Efficacy and Safety of PF-06651600(Ritlecitinib),a NovelJAK3/TEC Inhibitor,in Patients With Moderate-to-Severe Rheumatoid Arthritisand an Inadequate Response to Methotrexate.Arthritis Rheumatol.2020,72(10),1621-1631.)
综上所述,提高JAK抑制剂对于JAK3激酶的活性和选择性,减少脱靶标效应,对于解决目前JAK抑制剂使用过程中出现的疗效不佳和安全性问题具有非常重要的意义。

实施例136本发明公开的化合物的JAK3激酶抑制活性(实验委托桑迪亚医药技术(上海)有限责任公司开展)
实验目的:
采用Mobility shift assay方法,检测受试化合物(列表见下)对JAK3激酶酶活的体外抑制活性。以Cerdulatinib(供应商:selleckchem;货号:S7634)作为阳性对照化合物。
实验方法:
1.化合物配制
化合物溶解在100%DMSO中,配制成10mM储存液,-20℃冰箱避光保存。
2.激酶反应过程
(1)配制1×Kinase buffer。
(2)化合物浓度梯度的配制:受试化合物(包括实施例化合物及PF-06651600)测试浓度为10000n M,10倍稀释,10个浓度,单孔检测。在384孔板中梯度稀释成100倍终浓度的溶液。然后用Echo550转移250nL到384反应板中备用。阴性对照孔和阳性对照孔中分别加250nL的100%DMSO。
(3)用1×Kinase buffer配制2.5倍终浓度的激酶溶液。
(4)在化合物孔和阳性对照孔分别加10μL的2.5倍终浓度的激酶溶液;在阴性对照孔中加10μL的1×Kinase buffer。
(5)1000rpm离心30秒,振荡混匀后室温孵育10分钟。
(6)用1×Kinase buffer配制25/15倍终浓度的ATP和Kinase substrate 22的混合溶液。
(7)向384反应板化合物孔、阳性对照孔和阴性对照孔分别加入15μL的25/15倍终浓度的ATP和底物的混合溶液,起始反应。
(8)将384孔板1000rpm离心30秒,振荡混匀后室温孵育30分钟。
(9)加入30μL终止检测液停止激酶反应,1000rpm离心30秒,振荡混匀。
(10)用Caliper EZ Reader读取转化率。
3.数据分析
(1)计算公式
%Inhibition=(Conversion%_max-Conversion%_sample)/(Conversion%_max-Conversion%_min)×100
其中:Conversion%_sample是样品的转化率读数;Conversion%_min:阴性对照孔均值,代表没有酶活孔的转化率读数;Conversion%_max:阳性对照孔均值,代表没有化合物抑制孔的转化率读数;%Inhibition表示百分比抑制率。
(2)拟合量效曲线
以浓度的log值作为X轴,百分比抑制率为Y轴,采用分析软件GraphPad Prism 5的log(inhibitor)vs.response-Variable slope拟合量效曲线,从而得出各个化合物对酶活性的IC50值。计算公式是Y=Bottom+(Top-Bottom)/(1+10^((LogIC50-X)*HillSlope))。
实验结果:
与阳性对照PF-06651600相比,本发明申请的化合物母核结构不同,结构上的区别特征十分显著。上表数据表明,本发明申请的大部分化合物相对于PF-06651600具有更优的JAK3体外激酶抑制活性,部分化合物对于JAK3激酶的抑制活性是PF-06651600的10倍以上,在激酶抑制活性上具有显著的技术效果。通过对比实施例YZ001003与YZ001001对比发现,两者具有相同的分子骨架,只是YZ001001的NH基团上连接共价靶头,而YZ001003的NH基团上连接非共价靶头,前者具有良好的JAK3激酶抑制活性,后者基本没有抑制活性;通过对比实施例YZ001011、YZ001012与YZ001017对比发现,两者具有相同的分子骨架,只是YZ001017的NH基团上连接共价靶头,而YZ001011、YZ001012的NH基团上连接非共价靶头,YZ001017的JAK3抑制活性显著优于YZ001011、YZ001012。上述对比说明,本发明申请的化合物的共价靶头对于JAK3激酶的抑制活性十分关键,申请人推测共价靶头能与JAK3激酶Cys909氨基酸形成共价作用力。

实验目的:
测试YZ001052、YZ001054、YZ001065、YZ001085在SRBC小鼠模型的免疫抑制活性。以PF-06651600作为阳性对照化合物。
实验方法:
药物配制:称取化合物,加入0.5%的CMC-Na溶液制成药物混悬液(给药剂量为10mg/mL)。
迟发性变态反应(DTH)的诱导及给药:Balb/c小鼠雄性30只,称重,按体重随机分为6组,每组5只。实验周期共计7天。第0天皮下注射绵羊红细胞(SRBC)致敏。从第0天开始灌胃给药100mg/kg(一天一次)至第6天。第6天在小鼠右后脚垫注射SRBC进行激发。实验第7天测量拍照,结束实验。
疾病模型药效学检测指标:检测及观察指标为SRBC诱导小鼠造模爪部脚垫的红肿程度及厚度检测。在第6天SRBC注射激发前测量右爪的厚度作为基线。在实验结束时0再次测量右爪的厚度,计算二次注射前后爪厚度差。
统计学处理:实验数据采用均数±标准差(Mean±SD)表示,所有数据均采用T-test进行统计,以P<0.05为具有统计学差异,结果见图1。
实验结果:
由图1可知,SRBC诱导后(造模组)小鼠右爪厚度显著增加,药物处理后(包括化合物YZ001052、YZ001054、YZ001065、YZ001085)小鼠右爪厚度均出现不同程度的改善,表明化合物YZ001052、YZ001054、YZ001065、YZ001085对SRBC诱导的小鼠迟发性变态反应具有显著的免疫抑制作用,其作用效果非劣于PF-06651600。
实施例142:化合物对胶原诱导型小鼠关节炎模型的免疫抑制作用
1、胶原诱导型小鼠关节炎模型(mCIA)的构建
实验目的:测试YZ001052在mCIA模型的免疫抑制活性。以PF-06651600作为阳性对照化合物。
实验方法:将32只雌性DBA/1J小鼠随机分为4组,设置为空白对照组、模型组、模型+YZ001052给药组、模型+PF-06651600给药组。关节炎造模成功后,给予YZ001052或PF-06651600药物干预,50mg/kg,一天一次。分别将完全和不完全弗氏佐剂与鸡II型胶原液等比例混合形成乳化剂。除空白对照组外,Day 0时将完全弗氏佐剂和鸡II型胶原液的混合物皮下注射到小鼠尾根部和大腿根部,每只小鼠尾根部皮下注射100μL;两大腿根部皮下各注射50μL(初次免疫)。第21天时小鼠皮下注射200μL不完全弗氏佐剂和鸡II型胶原液的混合物作为加强注射(第二次免疫)。以至少有1只肢体临床积分≥2分以上,判断为关节炎发生。足爪厚度测量:采用游标卡尺测量小鼠左右后足的厚度即为足爪肿胀度并记录,检测频率为每3天一次。
实验结果:从图2可以看出,二次免疫后,模型组小鼠足爪部位炎症不断加重,肿胀逐渐蔓延至整个足爪,关节炎分数于第16天显著升高。而经YZ001052或PF-06651600治疗后,CIA小鼠的足爪肿胀程度得到了不同程度的改善,关节炎分数出现显著下降(与模型组相比)。
与关节炎评分一致,模型组小鼠足爪出现明显肿胀,而经YZ001052或PF-06651600治疗后,小鼠的足爪肿胀程度得到了不同程度的改善。以上结果说明,YZ001052或PF-06651600能够改善类风湿关节炎的症状。
实施例143:化合物对葡聚糖硫酸钠(DSS)诱导的小鼠炎症性肠病模型的免疫抑制作用
实验目的:测试YZ001052在DSS诱导的小鼠炎症性肠病模型的免疫抑制活性。以PF-06651600作为阳性对照化合物。
实验方法:32只雌性C57BL/6小鼠,随机分为4组,分别为空白对照组、模型组、模型+YZ001052给药组、模型+PF-06651600给药组。在造模开始时同时给药,YZ001052和PF-06651600的给药剂量为50mg/kg,一天一次。称量50g DSS,加入1000mL无菌水,配制成5%DSS溶液,用0.22μm滤膜过滤。于第0天起,空白组给予不含DSS的饮用水,其余实验组给予含5%DSS的饮用水。在第8天处死所有小鼠。在实验结束后,收集结直肠,进行拍照并测量其长度,进行统计学分析。
实验结果:如图3所示,与正常对照组相比,模型组小鼠的结直肠长度显著缩短,提示炎症性肠病小鼠的结直肠受到严重损伤。与模型组小鼠相比,YZ001052治疗组小鼠的结直肠长度明显增加,表明YZ001052治疗可以缓解炎症性肠病小鼠的结直肠损伤,结果优于PF-06651600。
实施例144化合物对放射性肺损伤小鼠模型的免疫抑制作用
1、急性放射性肺损伤小鼠模型的构建
(1)动物的分组及给药
18只雌性C57BL/6小鼠,随机分成3组,分别为空白对照组、单纯辐照组、辐照+药物YZ001052(30mg/kg q.d)干预组,每组6只。
(2)造模方法
用1%戊巴比妥钠以腹腔注射的方式麻醉小鼠,利用小动物精准放疗研究平台(SARRP),采用220KV X射线,单次全肺照射22.5Gy。照射完毕后小鼠常规饲养。
2、指标检测
造模3周后,麻醉小鼠,解剖并暴露肺组织,结扎左肺,进行开放性气管切开术,冷PBS灌洗肺部,收集肺泡灌洗液(BALF),4℃冷冻离心。
收集上清后,ELISA检测炎症因子TNF-α的含量。如图4所示,辐照诱导以后,模型组小鼠肺泡灌洗液中TNF-α水平明显升高。药物YZ001052对TNF-α的水平有较好的抑制作用。
用200μL PBS重悬肺泡灌洗液细胞沉淀,用于白细胞(WBC)计数。如图5所示,辐照诱导以后,模型组小鼠肺泡灌洗液中白细胞数目明显增多。药物YZ001052可显著降低辐照引起的小鼠肺部炎症细胞浸润数目。
