Description
技术领域
生物医药技术领域,具体涉及CpG类药物和蒽环类药物的一种复合物、制备方法和用途。
背景技术
恶性肿瘤是严重危害人类生命健康的常见病,已成为全球一个主要死亡原因。由于癌症的发生是一个逐步积累的过程,发病率与死亡率随着年龄的增大呈现指数上升的趋势。而我国随着国民经济的发展、医疗卫生的进步和预期寿命的延长,人口分布已进入老龄化阶段,且主要人口年龄分布仍在逐年增大,老龄化日趋严重,同时环境污染依然严重使恶性肿瘤已成为我国疾病死亡的第一杀手。
目前临床上治疗癌症的手段主要是手术、放疗和化疗。手术治疗是治疗肿瘤最有效的方法,但是单纯依靠手术很难防止肿瘤复发和远处转移,难以达到根治的目的;放射治疗虽然对某些肿瘤具有根治的效果,但还有一定的局限性。放射治疗是通过射线杀灭肿瘤细胞,这能对局部病灶有治疗作用,不能预防肿瘤的远处转移,对于一些射线不敏感的肿瘤细胞不能全部杀死,导致肿瘤残留和复发;化学治疗对某些肿瘤的治愈率比较高,但化学药物对肿瘤细胞杀伤的选择性不强,毒性较大。由于传统的手术、放化疗的发展已进入平台期,人们把越来越多地目光投到肿瘤的生物治疗上。“癌症免疫治疗”通过增强抗肿瘤免疫应答和打破肿瘤的免疫抑制调动机体的免疫系统,增强抗肿瘤免疫力,从而杀伤肿瘤细胞、抑制肿瘤生长,在多种类型癌症中的具有良好治疗功效,并且免疫治疗与化疗、放疗等传统治疗方法相比,具有相对毒副作用小、疗效显著等优势,因此正受到越来越多的关注。
CpG类药物是包含CpG基序的寡脱氧核苷酸,其能够整体上刺激人体免疫系统,启动先天免疫应答以及细胞免疫和体液免疫机制,增强人体抗肿瘤免疫能力。 CpG类药物经胞吞作用进人细胞,与细胞质中的TLR9(toll-like receptor 9)相互作用,并通过MyD88和TRAF6(tumor necrosis factor receptor-associated factor 6) 的活化导致IkB降解,从而激活转录因子NFkB,通过NFkB诱导某些细胞因子基因的转录。CpG也能作用于其他信号通路,如激活MAPK(mitogen-activated protein kinase)和应激激酶途径如JNKK1,并最终激活细胞因子的转录,通过细胞因子激活机体免疫应答;并且,CpG类药物能诱导单核细胞、巨噬细胞、树突状细胞等固有免疫细胞分泌多种细胞因子及趋化因子如IFN-a、IL-12、TNF-a、IP10、 NO等,并上调协同刺激分子,诸如CD80、CD86。这些变化将增强先天免疫应答非特异地杀伤肿瘤细胞,使APC(antigen presenting cell)的抗原提呈能力提高、 Th0细胞向Th1细胞型分化,从而更有效地激活T细胞介导的肿瘤特异的细胞免疫应答;同时,CpG能刺激B细胞扩增,并阻止B细胞凋亡,同时能直接激活B细胞。活化的B细胞分泌IL-6、IL-10等细胞因子和免疫球蛋白Ig M,并使细胞表面的Fcγ受体和MHCⅡ、CD80、CD86等辅助刺激分子表达上调,从而增强人体抗肿瘤体液免疫应答。
但是肿瘤自身经过DNA突变或基因表达改变调整抗原表达使某些变异肿瘤细胞耐受或抑制抗肿瘤免疫应答,从而发挥免疫逃逸。有研究表明,低剂量的蒽环类药物能够破坏恶性肿瘤并激发免疫系统识别的机制引起肿瘤免疫原性死亡,进而将肿瘤细胞转化为肿瘤疫苗,使“冷肿瘤”变成“热肿瘤”,引起适应性免疫应答。而且CpG药物药物可以和蒽环类药物自组装形成复合物,该复合物在体液中性环境下稳定存在,到达肿瘤酸性环境后解离,解离后蒽环类药物进入肿瘤细胞核使肿瘤细胞发生免疫原性死亡,CpG作用于胞内的TLR9,刺激其分泌细胞因子并激活机体免疫应答。因此将CpG类药物与蒽环类药物联合不仅能够提高肿瘤细胞的免疫应答能力,具有酸响应性,能够智能高效的消灭肿瘤。
基于CpG类药物与蒽环类药物形成复合物的机制,专利CN 101269223B发明了一种蒽环类药物纳米剂型,其中使用核酸做为蒽环类药物与阳离子化合物复合的媒介,蒽环类药物含量较高。该专利主要是通过阳离子的引入提高蒽环类药物的利用度,进而提高蒽环类药物细胞毒效果。但是较高含量的蒽环类药物存在剂量依赖的心脏毒性,表现为各种心律失常,累计剂量大时还会发生心肌坏死甚至充血性心力衰竭。并且,蒽环类药物的细胞毒性是非特异性的,其不仅可以杀死肿瘤细胞还能杀死免疫细胞及正常细胞,因此高比例的蒽环类药物将会降低CpG 类药物发挥免疫激活作用,不利于免疫治疗。

6 | 1:1 | 58 |
注:抑瘤率计算方法:抑瘤率=1-(给药组小鼠的平均肿瘤体积/生理盐水组小鼠的平均肿瘤体积)
7、结论:结合上表以及图2可以看出,CpG类药物与蒽环类药物剂量比为30:1 时抑瘤率为45%,这主要是由于蒽环类药物含量过低,两种药物没有起到协同作用导致的。当CpG类药物与蒽环类药物剂量比为1:1时抑瘤率为58%,这主要是由于蒽环类药物发挥了细胞毒作用限制了免疫作用,并受给药方式和给药剂量的限制其抑瘤效果有限。而CpG类药物与蒽环类药物剂量比为3:1、10:1和20:1时,肿瘤抑瘤率分别达到71%、80%和68%,说明在此剂量比范围内具有较高的抗肿瘤活性。

注:抑瘤率计算方法:抑瘤率=1-(给药组小鼠的平均肿瘤体积/生理盐水组小鼠的平均肿瘤体积)
7、结论:CpG类药物与蒽环类药物复合物具有最佳的抑瘤效果;在停药后七天第二次接种肿瘤细胞后,生理盐水组在接种后第五天出瘤,并且五只小鼠全部出瘤,而CpG类药物与蒽环类药物复合物组在第10天才出瘤,仅仅两只小鼠长出瘤来,效果优于生理盐水组、CpG-1组和多柔比星组,说明CpG类药物与蒽环类药物复合物能够激发并持久保持免疫应答,使小鼠出瘤时间延长,出瘤只数减少;从图2的生存期数据可以看出,CpG类药物与蒽环类药物复合物降低其体内毒性,显著延长了小鼠的生存期。总之CpG类药物与蒽环类药物复合物具有理想的抑瘤效果并延长了小鼠生存期,是一种很有潜力的抗肿瘤治疗模式。

6、实验结果
表八、抑瘤率
组别 | 抑瘤率(%) |
多柔比星 | 51 |
CpG&DOX复合物 | 83 |
CpG&DOX复合物脂质体 | 86 |
注:抑瘤率计算方法:抑瘤率=1-(给药组小鼠的平均肿瘤体积/生理盐水组小鼠的平均肿瘤体积)7、结论:
抑瘤率数据可以看出,CpG&DOX复合物和CpG&DOX复合物脂质体抑瘤率高达83%和86%,而单独的化疗药多柔比星抑瘤率仅为51%,说明CpG和多柔比星形成的复合物及脂质体能够显著提高抑瘤效果。
图3中可以看出多柔比星由于其强烈的毒副作用,体重显著降低,体重下降27.5%。而CpG&DOX复合物和CpG&DOX脂质体体重和生理盐水相比没有显著变化,随着时间延长,体重逐渐上升,说明CpG&多柔比星复合物和CpG&多柔比星脂质体给药组小鼠状态良好,显著降低了多柔比星的毒副作用,体内安全性较高。
综上所述,CpG&蒽环类复合物和CpG&蒽环类脂质体不仅可以提高对肿瘤的抑制作用,还具有较高的体内安全性,是一种很有潜力的抗肿瘤治疗药物。
