背景技术
维甲酸相关孤儿核受体(Retinoid-related orphan receptors,ROR)是核受体家族的成员之一，也是一类配体依赖的转录因子，它能够调控多种生理和生化过程，包括生殖发育、新陈代谢、免疫系统调节等(Mech Dev.1998Jan,70(1-2:147-53；EMBO J.1998Jul 15,17(14):3867-77)。ROR家族包括三种类型RORα、RORβ和RORγ(Curr Drug Targets Inflamm Allergy.2004Dec,3(4):395-412),其中RORγ可以在许多组织中表达，包括胸腺、肝脏、肾脏、脂肪和骨骼肌等(Immunity.1998Dec,9(6):797-806.)。
RORγ有两种亚型：RORγ1和RORγt(RORγ2)，其中RORγ1在许多组织中表达，如：胸腺、肌肉、肾脏和肝脏中表达，而RORγt则只在免疫细胞内表达(Eur J Immunol.1999Dec,29(12):4072-80)。已有文献报道，RORγt能够调节在免疫细胞分化的过程中T细胞的存活，并能激活和促进CD4+、CD8+的细胞分化成辅助T细胞17(Th17)和细胞毒性T细胞(Tc17)(J Immunol.2014Mar 15,192(6):2564-75)，其中TH17和Tc17细胞是一类效应细胞，通过分泌白介素17(IL-17)和其他炎症因子(如IL-21)促进炎症反应、增强获得性免疫反应和自身免疫应答。此外，现有研究证明，通过将Th17和Tc17细胞移植到荷瘤小鼠中，可以明显抑制移植瘤的生长(J Immunol.2010Apr 15,184(8):4215-27)。Th17还可以招募细胞毒性CD8+T细胞和自然杀伤细胞进入肿瘤微环境，从而杀死肿瘤细胞，达到抗肿瘤的目的(Blood.2009Aug 6,114(6):1141-9；Clin Cancer Res.2008Jun1,14(11):3254-61)。因此，激活RORγt，有可能成为新的抗肿瘤疗法。
目前，已有医药公司开发出RORγt的激动剂，比如Lycera Corp.公司开发的小分子药物LYC-55716。临床前研究表明，其类似物LYC-54143可通过两条不同的通路抑制肿瘤生长，表现出优越的抗癌活性。首先，LYC-54143激活RORγt后可通过传统途径调节Th17和Tc17细胞的分化，促进IL-17等其他细胞因子的表达，提高T细胞活性。另外，激活的RORγt可以调节免疫系统中的多种基因表达，抑制细胞检查受体PD-1的表达，从而降低免疫抑制，提高抗癌活性(Oncoimmunology.2016Nov 4,5(12):e1254854；ACS Chem Biol.2016Apr 15,11(4):1012-8)。虽然 LYC-55716目前已经进入临床II期，但是有关该靶点激动剂的药物仍然非常少，并且无上市药物出现，已公开的专利有如WO2015171558、WO2008152260、WO2007068580、WO2007068579、WO2005056516、WO2005056510、WO2005066116、WO00228810，仍需要继续开发更高效的新的RORγt激动剂，以期为患者提供新的有效的抗癌药物。
本发明人设计具有通式(I)所示结构的吲哚甲酰胺类化合物，表现出显著的激动ROR的作用。在研究ROR激动剂的过程中，发明人还发现在本发明所述的通式(I)所示的化合物中，环A邻位基团的变化会改变其调节效果，当环A邻位基团为位阻较小的基团(例如H)时通式(I)所示的化合物为反激动剂，当环A邻位基团为卤代烷基(例如三氟甲基)、烷基(例如乙基)和卤代烷氧基(例如三氟甲氧基)类位阻较大的基团时通式(I)所示的化合物为ROR激动剂。本发明还提供了药效试验，单独施用本发明化合物时表现出良好的抑瘤活性，另外，本发明化合物与PD-1抗体联合用药时表现出协同作用，为提高免疫治疗的疗效开辟了新途径。

药效学评价
测试例4、RORγ激动剂在同种型MC38结肠直肠肿瘤小鼠模型的药效
1.实验目的
用MC38小鼠模型来评估实施例4化合物对MC38肿瘤生长的抑制作用。
2.实验方法和实验材料
2.1.实验动物和饲养条件
实验用雌性C57BL/6小鼠，购自Charles River Lab(美国)，购入时20-25克，7-9周龄。10只/笼饲养，温度23±1℃恒温，湿度50～60％，自由进食进水。一切按照实验动物护理和使用委员会(IACUC批准指南)进行护理和使用。动物购进后，进行7天适应性饲养后开始实验。
2.2.实验药品
实施例4化合物；
抗鼠PD-1(CD279)抗体购自BioXcell(克隆RMP1-14；目录编号BP0146)；
IgG2a同型对照抗体购自BioXcell(克隆2A3；目录编号BE0089)。
2.3.实验设计和实验方法
2.3.1.动物分组：
小鼠适应性饲养后，分组如下：
分组 n 给药方式 给药方案
IgG2a同型对照抗体加载体对照组 8 腹腔注射/口服 Q3dx4/BIDx21
抗鼠PD-1抗体 8 腹腔注射 Q3dx4
实施例4化合物 8 口服 BIDx21
抗鼠PD-1抗体加实施例4化合物 8 腹腔注射/口服 Q3dx4/BIDx21
注：1.Q3dx4代表每隔三天给药，总共给四次，固定在第5，8，11，14天给药；
2.BIDx21代表每天给药2次，连续给药21天；
2.3.2.实验方法：
实验使用雌性C57BL/6小鼠(20-25克，7-9周龄)。通过检测同种型MC38结肠直肠肿瘤(Synta Pharmaceuticals)在自交系C57BL/6小鼠的生长情况评估单独施用实施例4化合物或实施例4化合物与抗鼠-PD-1抗体联合施用的体内抗肿瘤活性。将五十万(5×10  5)MC38细胞植入每只小鼠的右侧腹部皮下，待5天后当肿瘤生长至40-80mm 3后，将小鼠随机分组，每天施用实施例4化合物(30mg/kg) 2次，连续给药21天。在抗体单用或与实施例4化合物联合施用治疗实验中，固定在第5、8、11、14天分别对携带MC38肿瘤的小鼠腹腔(i.p.)注射抗鼠PD-1(CD279)抗体(BioXcell)(5mg/kg)。对照组是载体CMC-Na药剂配方与IgG2a同型对照抗体。
2.4.数据表达：
用卡尺在三个维度中测量肿瘤体积，然后根据下式计算：肿瘤体积(mm 3)＝l×w×h×0.5236，其中，1表示肿瘤长度，w表示肿瘤的宽度，h表示肿瘤的高度，单位为毫米。肿瘤生长抑制率TGI％＝100x(TV 对照-TV 肿瘤)/(TV 对照-TV 初始)，其中TV 对照＝对照组的肿瘤体积；TV 肿瘤＝治疗组的肿瘤体积；TV 初始＝5天时起始肿瘤体积。
3.结果和讨论：
如图1所示，单独施用30mg/kg实施例4化合物时，TGI为40％。单独注射抗鼠PD-1(CD279)抗体(5mg/kg)时，TGI为51％。当与抗鼠PD-1单克隆抗体(5mg/kg)联合施用时，实施例4化合物(30mg/kg)表现出协同效应(TGI为63％。这些数据表明了在同基因的MC38结肠直肠肿瘤模型中，单独施用实施例4化合物表现出抑瘤活性，同时实施例4化合物与PD-1抗体联合施用表现出协同作用，这也表明实施例4化合物具有与RORγ激活(而非抑制)一致的生物活性，为提高免疫治疗的疗效开辟了新途径。
