Description
技术领域
本发明涉及生物医药领域,具体地,涉及EP4受体拮抗剂和PD-1抑制剂联合用于癌症的治疗。
背景技术
癌症已成为威胁人类生命健康最可怕的杀手之一,国际癌症研究机构(IARC)发布的2018年《全球癌症报告》数据显示,2018年全球新增1810万癌症病例,约960万人将死于癌症,且发病率和死亡率还在逐年攀升。报告称,我国的癌症发病率和死亡率全球第一,其中,我国新增病例数占380.4万例,死亡病例数占229.6万例。
继手术治疗、放射治疗和化疗药物治疗之后,以免疫检查点抑制剂为代表的肿瘤免疫治疗的发展,推动了癌症治疗革命性的变化。
然而目前的免疫检查点抑制剂在治疗癌症,尤其是恶性肿瘤方面有很多的缺点,比如对晚期实体瘤的客观响应率低(一般,客观缓解率<30%);诱发多种致死性的副作用,包括结肠炎、神经毒性、肺炎、肝炎、下垂体炎、肾炎、肾上腺炎和心脏疾病,这些因素导致的死亡人数最多,为最主要的致死性副作用。
因此,本领域迫切需要开发可有效治疗癌症,尤其是恶性肿瘤的药物。
发明内容
本发明的目的在于开发可有效治疗癌症,尤其是恶性肿瘤的药物。
本发明第一方面提供了一种产品组合,包括:
(i)第一药物组合物,所述第一药物组合物含有(a)第一活性成分,所述第一活性成分为EP4受体拮抗剂,以及药学上可接受的载体;和
(ii)第二药物组合物,所述第二药物组合物含有(b)第二活性成分,所述第二活性成分为PD-1抑制剂,以及药学上可接受的载体;
其中,所述的第一药物组合物和第二药物组合物为不同的药物组合物,或同一药物组合物。
在另一优选例中,所述EP4受体拮抗剂是式I所示的化合物或其药学上可接受的盐或水合物:
为取代或未取代的选自下组的环:C4-C7碳环、4-7元饱和杂环、苯环、4-7元不饱和杂环(包括杂芳环),其中,所述的杂环上具有一个或多个选自下组的杂原子:O、S或NR6;所述的环可以是单环、二环、螺环或桥环;
X为选自下组的基团:-O-、-S-、-N(R7)-;
Y为无,或者为选自下组的基团:-CH2-、-O-、-S-、-SO-、-SO2-、-N(R8)-;
B1和B2各自独立地为选自下组的基团:无、C1-C6的亚烷基、C2-C6的亚烯基、C2-C6的亚炔基;优选地,所述的B1和B2独立地选自下组:-(CH2)n-;其中n=0、1、2、3或4、-CH=CH-、-CH=CH-CH2-、-CH2-CH=CH-、-CH=CH-CH2-CH2-、-CH2-CH=CH-CH2-、-CH2-CH2-CH=CH-;-C≡C-、-C≡C-CH2-、-CH2-C≡C-、-C≡C-CH2-CH2-、-CH2-C≡C-CH2-、-CH2-CH2-C≡C-;且B1、B2和Y不同时为无;

PD-1/PD-L1信号通路
PD-1/PD-L1信号通路是负调控T细胞活化的关键信号通路,当肿瘤杀伤性T细胞浸润在肿瘤组织中时,激活的T细胞能分泌干扰素-γ(TNF-γ)等细胞因子,这些细胞因子通过一系列信号转导过程会诱导巨噬细胞、T、B细胞和肿瘤细胞上表达PD-L1,进而与T细胞上的PD-1受体发生相互作用,引起T细胞的失活和凋亡,促进肿瘤细胞的发生发展。PD-1/PD-L1通路抑制剂可以阻断PD-1和PD-L1结合,阻断负向调控信号,从而使肿瘤杀伤性T细胞恢复杀伤能力,从而增强对肿瘤细胞的免疫应答。

前列腺素E2(Prostaglandin E2,PGE2)是在人体中的含量和分布最丰富广泛的前列腺素亚型。它参与调控了包括炎症、疼痛、肾功能、心血管系统、肺功能以及癌症在内的诸多生理和病理过程。PGE2通过自分泌或旁分泌的方式结合到细胞表面的G蛋白偶联受体EP1,EP2,EP3,EP4(也称为PTGER1,PTGER2,PTGER2和PTGER4)四个不同亚型上,而这些G蛋白偶联受体亚型通过偶联不同的G蛋白激活不同的下游信号通路发挥其生物学效应。尽管EP2和EP4受体亚型均通过偶联Gs蛋白介导下游信号,但由于它们氨基酸序列仅有31%的同源性,存在一定的结构差异,因此它们发挥的主要生理功能虽具有相似之处,但也存在着诸多不同。

实施例2本发明化合物YJ114与PD-1抗体联用对小鼠CT26结肠癌肿瘤模型的抑制作用
1.小鼠CT26细胞结肠癌皮下移植模型及给药方案
体外培养扩增小鼠结肠癌细胞CT26,并以1×106细胞/100μL在6-8周雌性Balb/c小鼠背部右侧皮下注射荷瘤。之后采用游标卡尺测量小鼠背部皮下肿瘤的长和宽,并计算肿瘤体积(mm3)=长(mm)×宽(mm)×宽(mm)×0.5。待小鼠背部肿瘤体积大小达到100mm3-200mm3后,将小鼠随机分为四组:对照组,YJ114单药组,PD-1抗体单组和联药组。YJ114的给药剂量为75mg/kg/d,给药方式为口服;PD-1抗体的给药剂量为50μg/只,一周两次,给药方式为腹腔。给药周期为20天。每两天测量记录小鼠的肿瘤大小和体重变化。
2.实验结果分析:
结果如图1A-C所示,与阴性对照组相比,YJ114及PD-1抗体单药组均能在一定程度抑制肿瘤的生长,且PD-1抗体组的治疗效果要优于75mg/kg/d的YJ114单药组,肿瘤生长得到了很大程度的缓解。与此同时,联药组的抗肿瘤生长效果比PD-1抗体单独使用的抑制效果更好,12只小鼠中8只小鼠的肿瘤体积减小消失,得到完全缓解(对照组:0/12;YJ114单药组:2/12;PD-1抗体单药组:4/12;YJ114+PD-1抗体联药组:8/12),而对小鼠的体重没有任何不良影响,说明YJ114与PD-1抗体联合使用对小鼠没有明显的毒副作用。
为了进一步探究YJ114与PD-1抗体联合用药的长期治疗效果,将CT26荷瘤小鼠按上述分组及给药方式给药2周后,继续测量记录小鼠的肿瘤大小,规定小鼠肿瘤体积超过2000mm3为死亡,统计并从给药开始为期四个月的各组小鼠存活曲线。结果如图1D所示,YJ114及PD-1抗体单药组都在一定程度上延长了小鼠的生存周期,而联药组的小鼠存活期更久,与其他各组存在显著性差异。到统计时间终点120天时,联药组仍有7只小鼠存活(对照组:0/12;YJ114单药组:1/10;PD-1抗体单药组:2/10;联药组:7/10)。
实施例3本发明化合物YJ114与PD-1抗体联用对小鼠MC38结肠癌肿瘤模型的抑制作用
1.小鼠MC38细胞结肠癌皮下移植模型及给药方案
体外培养扩增小鼠结肠癌细胞MC38,并以1×106细胞/100μL在6-8周雌性C57BL/6小鼠背部右侧皮下注射荷瘤。之后采用游标卡尺测量小鼠背部皮下肿瘤的长和宽,并计算肿瘤体积(mm3)=长(mm)×宽(mm)×宽(mm)×0.5。待小鼠背部肿瘤体积大小达到100mm3-200mm3后,将小鼠随机分为四组:对照组,YJ114单药组,PD-1抗体单药组和联药组。YJ114的给药剂量为75mg/kg/d,给药方式为口服;PD-1抗体的给药剂量为50μg/只,一周两次,给药方式为腹腔。给药周期为18天。每两天测量记录小鼠的肿瘤大小和体重变化。
2.实验结果分析:
结果如图2A-C所示,与阴性对照组相比,YJ114及PD-1抗体单药组均能在一定程度抑制肿瘤的生长,且PD-1抗体单药组的治疗效果与YJ114给药组的药效相当。与此同时,YJ114与PD-1抗体联合使用的抗肿瘤生长效果比两组单药的抑制效果更好,8只小鼠中3只小鼠的肿瘤体积减小消失,得到完全缓解而对小鼠的体重没有任何不良影响,而其他组并无肿瘤完全消失的现象。实验结束后称取各组小鼠肿瘤组织重量,统计结果与肿瘤体积类似,联合用药组的肿瘤生长抑制效果最为明显,且对小鼠没有明显的毒副作用。
实施例4本发明化合物YJ114与PD-1抗体联用对AOM/DSS模型诱导的小鼠原位结肠癌肿瘤模型的抑制作用
慢性炎症一直被认为是结直肠癌发生大的诱因之一并伴随着结直肠癌的发生发展。IL-6、TNF、IL-1β、IL-17等这些炎性细胞因子和多种免疫细胞在形成慢性炎症的环境中充当了肥沃的土壤,不断积累而促进结直肠癌的发展。而AOM/DSS模型是通过化学刺激造成小鼠肠道细胞损伤进而形成局部溃疡性结肠炎,在长期诱导剂的作用下进一步发展成结肠癌的模型。因此通过构建AOM/DSS模型将进一步验证通过YJ114阻断PGE2/EP4信号通路可以协同免疫检查点阻断剂抑制PD-1/PD-L1信号通路对原位肿瘤形成和生长产生更加有效而持久的抑制作用。
1.小鼠原位结肠癌模型及给药方案
如图3A所示,选取8-10周C57BL/6雌性小鼠,进行10mg/kg AOM一次性腹腔注射,第六天起连续2.5%的DSS给水5天后更换成正常饮用水两周,通过三轮含2.5%的DSS给水周期构建自发性小鼠的结肠癌模型。在第三轮含2.5%DSS给水结束后,我们按此时的小鼠体重随机分为四组:对照组,YJ114单药组,PD-1抗体单药组和联药组。YJ114的给药剂量为75mg/kg/d,给药方式为口服;PD-1抗体的给药剂量为50μg/只,一周两次,给药方式为腹腔。给药周期为35天。在给药周期结束后,我们取各组小鼠结肠部位并展开观察小鼠结肠内部肿瘤形成和生长情况。
2.实验结果分析:
结果如图3B-D所示,YJ114及PD-1抗体单药处理均能够在一定程度上缓解小鼠结肠部位肿瘤的形成,降低小鼠结肠部位肿瘤总数。与对照组相比,单独使用PD-1抗体对于直径大于4mm的肿瘤几乎没有抑制效果,而YJ114单药处理能显著抑制直径大于4mm的肿瘤的形成。相比之下,联药组小鼠的结肠部位的肿瘤数量的体积均有明显的减小,再次显示了YJ114与PD-1抗体能够产生很好地抗肿瘤协同效果。与此同时,我们测量统计了小鼠的结肠长度,发现各组之间并不存在显著性差异。
实施例5本发明化合物YJ114与PD-抗体联用对小鼠RM-1前列腺癌模型的抑制作用
1.小鼠RM-1细胞前列腺癌皮下移植模型及给药方案
将1×106个前列腺癌细胞RM-1,皮下注射到6~8周龄雄性C57BL/6小鼠右侧背部。按照公式:体积=长×宽2×0.52计算肿瘤体积。待肿瘤长到100mm3左右时,随机分为四组:对照组,YJ114单药组,PD-1抗体单药组和联药组,YJ114的给药剂量为150mg/kg/d,每天一次,给药方式为口服;PD-1抗体的给药剂量为100μg/只,一周两次,给药方式为腹腔,给药周期为17天。每周2次测量并记录肿瘤长与宽的变化,同时记录小鼠体重。待实验结束后,麻醉处死小鼠,剥离皮下肿瘤,称重并拍照记录肿瘤大小。
2.实验结果分析:
如图4A所示,在RM-1皮下荷瘤动物模型中,分别采取单用和联用的方式,测试YJ114与PD1抗体的治疗效果,PD1抗体和YJ114单药的肿瘤生长抑制率较为接近,仅为40%左右。但当YJ114和PD1抗体联用时,对肿瘤的抑制效果明显增加,达到了几乎完全抑制的效果,联合效果极为显著(图4A)。剥离肿瘤图片(图4B)及剥离肿瘤质量测量结果(图4C)也同样证明联合效果极为显著。此外,各组小鼠在治疗期间生理指标均正常,体重增长平稳(图4D)。此实验结果证明YJ114和PD-1单抗联合治疗显著抑制前列腺肿瘤生长。
用实施例2-5的方法,对本发明的其他化合物进行实验,结果表明,本发明的其他化合物具有与YJ114类似的活性和效果。
实施例6本发明化合物YJ114与PD-1抗体联用对小鼠MFC胃癌模型的抑制作用
1.小鼠胃癌MFC细胞皮下移植模型及给药方案
将2×106个小鼠胃癌MFC细胞,皮下注射到6~8周龄615小鼠右侧背部。按照公式:体积=长×宽2×0.52计算肿瘤体积。待肿瘤长到100mm3左右时,随机分为四组:对照组,YJ114单药组,PD1抗体单药组和联药组,YJ114的给药剂量为150mg/kg/d,每天一次,给药方式为口服;PD1抗体的给药剂量为10μg/只,一周两次,给药方式为腹腔,给药周期为27天。每周2次测量并记录肿瘤长与宽的变化,同时记录小鼠体重。待实验结束后,麻醉处死小鼠,剥离皮下肿瘤,称重并拍照记录肿瘤大小。
2.实验结果分析:
如图5A所示,在MFC胃癌皮下荷瘤动物模型中,分别采取单用和联用的方式,测试YJ114与PD1抗体的治疗效果,PD1抗体和YJ114单药的肿瘤生长抑制率较为接近,达到80%左右。且当YJ114和PD1抗体联用时,对肿瘤的抑制效果更加显著,几乎完全抑制肿瘤的生长(图5A)。在实验结束当日,对各组肿瘤消除率进行了统计。如图5B的结果所示,YJ114单药组的肿瘤消除率约50%,PD1单药组的肿瘤消除率约为70%,当两者联合时,肿瘤100%消除。以肿瘤体积超过2000mm3为小鼠死亡判定标准得到图5C所示的小鼠存活曲线,可见联合治疗显著延长实验小鼠生存期,实验结束时小鼠存活率为100%。整个实验过程中各组小鼠体重变化无明显差异(图5D)。
