Description

一种治疗肿瘤坏死因子家族相关疾病的联合用药物A combined drug for treating tumor necrosis factor family related diseases 技术领域Technical field

本发明涉及一种治疗肿瘤坏死因子家族相关疾病的联合用药物。The present invention relates to a combination drug for treating a tumor necrosis factor family related disease.

背景技术Background technique

自从Aggarwal等于1984年分离并鉴定出首个肿瘤坏死因子(tumor necrosis factor,TNF)后,至今这个蛋白家族已有近20名成员。TNF通过与其受体TNFR(TNF receptor,TNFR)相互作用在自身免疫性疾病、细菌及病毒感染、肿瘤、糖尿病、骨质疏松等多种疾病的发生与发展中起关键作用。因此,近年来TNF/TNFR家族的重要成员TNFα/TNFR、Fas/FasL和TRAIL/TRAILR成为重要的药物靶点,并开发出多个相关靶向药物,尤其是生物药物,其中有些在临床疗效和商业上获得巨大成功。Since Aggarwal et al. isolated and identified the first tumor necrosis factor (TNF) in 1984, the protein family has nearly 20 members. TNF plays a key role in the occurrence and development of autoimmune diseases, bacterial and viral infections, tumors, diabetes, osteoporosis and other diseases through its interaction with TNF receptor (TNFR). Therefore, in recent years, TNFα/TNFR, Fas/FasL and TRAIL/TRAILR, important members of the TNF/TNFR family, have become important drug targets, and a number of related targeted drugs have been developed, especially biopharmaceuticals, some of which are clinically effective and Business has been a huge success.

目前,治疗肿瘤坏死因子家族相关疾病的药物大多还处于临床前和临床阶段,只有少量药物已经开始上市销售。针对不同的TNF/TNFR家族成员,所开发的相关药物治疗病症也有差异,例如与TNFα抑制剂主要治疗类风湿性关节炎、节段性肠炎、强直性脊柱炎、银屑病关节炎等疾病;而TRAIL/TRAILR相关药物主要为抗肿瘤药物。At present, most of the drugs for treating tumor necrosis factor family related diseases are still in the pre-clinical and clinical stages, and only a small amount of drugs have been on the market. Different drug-related disorders have been developed for different TNF/TNFR family members, such as TNFα inhibitors mainly for the treatment of rheumatoid arthritis, segmental enteritis, ankylosing spondylitis, psoriatic arthritis and other diseases; The TRAIL/TRAILR related drugs are mainly anti-tumor drugs.

美国食品药品管理局(FDA)已批准5种TNFα抑制剂上市,这些药在治疗炎症及自身免疫性疾病中表现出很好的效果,但其所带来的风险也逐渐引起了人们的重视。已报道的TNFα抑制剂常见的不良反应包括引起恶性肿瘤,引发细菌、病毒、真菌的感染,药物的免疫反应,皮肤过敏反应等。因此,基于TNFα抑制剂的良好疗效以及并存的安全隐患,在不加大TNFα抑制剂用量的情况下,提高其药效,对降低TNFα抑制剂的不良反应显得尤为重要。另外,临床证明TRAIL/TRAILR相关药物具有抗肿瘤的功效,但是单独使用TRAIL作为抗肿瘤药物,难以取得满意的疗效,需要与其他化疗药物联合使用。The US Food and Drug Administration (FDA) has approved the listing of five TNFα inhibitors, which have shown good results in the treatment of inflammatory and autoimmune diseases, but the risks they pose are gradually gaining attention. Common adverse reactions that have been reported for TNFα inhibitors include causing malignant tumors, causing infections of bacteria, viruses, fungi, drug immune responses, skin allergic reactions, and the like. Therefore, based on the good efficacy of TNFα inhibitors and the coexisting safety hazards, it is particularly important to reduce the adverse effects of TNFα inhibitors without increasing the dose of TNFα inhibitors. In addition, TRAIL/TRAILR-related drugs have been clinically proven to have anti-tumor effects, but TRAIL alone as an anti-tumor drug is difficult to achieve satisfactory results and needs to be used in combination with other chemotherapeutic drugs.

绿原酸是一种具有强生物活性的天然物质,目前的临床试验已经证实,绿原酸是一种安全、无毒、广谱的抗肿瘤药物,可以用于包括肺癌、脑胶质瘤、肝细胞癌、淋巴细胞肿瘤等多种恶性肿瘤的治疗,同时机理研究显示,绿原酸主要通过调节机体T细胞介导的细胞免疫过程,发挥抗肿瘤作用。Chlorogenic acid is a natural substance with strong biological activity. Current clinical trials have confirmed that chlorogenic acid is a safe, non-toxic, broad-spectrum anti-tumor drug that can be used for lung cancer, glioma, The treatment of various malignant tumors such as hepatocellular carcinoma and lymphocyte tumor, and mechanistic studies show that chlorogenic acid plays an anti-tumor role mainly by regulating the cellular immune process mediated by the body T cells.

3.1联合用药对MCF-7干细胞的抑制作用3.1 Inhibition of MCF-7 stem cells by combination therapy

计算不同浓度药物组合对MCF-7干细胞的抑制作用,结果如图3所示,绿原酸联合TRAIL对MCF-7干细胞的抑制作用,普通高于单药组(绿原酸单药或TRAIL单药)。对上述实验结果按照联合用药指数法进行分析后,算得联合用药的联合用药的Q值,绿原酸联合TARIL具有协同作用,在不同的药物浓度组合下,这种协同作用的强度有所不同。结果如表10所示:The inhibitory effects of different concentrations of drug combinations on MCF-7 stem cells were calculated. The results are shown in Figure 3. The inhibitory effect of chlorogenic acid combined with TRAIL on MCF-7 stem cells is generally higher than that of the monotherapy group (chlorogenic acid monotherapy or TRAIL single). medicine). After the above experimental results were analyzed according to the combined drug index method, the Q value of the combination drug was calculated, and chlorogenic acid combined with TARIL had a synergistic effect, and the intensity of this synergistic effect was different under different drug concentration combinations. The results are shown in Table 10:

实验结果表明:绿原酸联合TARIL对MCF-7干细胞具有显著的抑制作用,从而达到协同增效的作用。The experimental results show that chlorogenic acid combined with TARIL has significant inhibitory effect on MCF-7 stem cells, thus achieving synergistic effect.

综上,本发明绿原酸与治疗肿瘤坏死因子家族相关疾病药物的联合使用治疗肿瘤坏死因子家族相关疾病可以发挥协同增效的作用,提高单用TNF-α抑制剂的疗效,减轻类风湿性关节炎患者关节腔内的炎性浸润及关节软骨的侵蚀程度;增强urelumab抑制肿瘤发展的疗效;提高TARIL对癌细胞的抑制率;将绿原酸与肿瘤坏死因子家族相关药物制成联合用药物具有明显的协同增效的作用,疗效优良,毒性小,临床应用前景良好。In summary, the combination of the chlorogenic acid of the present invention and a medicament for treating a tumor necrosis factor family-related disease can synergistically enhance the tumor necrosis factor family-related diseases, improve the efficacy of the TNF-α inhibitor alone, and reduce the rheumatoidity. Inflammatory infiltration in the joint cavity of arthritis patients and the degree of erosion of articular cartilage; enhance the efficacy of urelumab in inhibiting tumor development; increase the inhibition rate of TARIL on cancer cells; and make medicinal drugs related to chlorogenic acid and tumor necrosis factor family It has obvious synergistic effect, excellent curative effect, low toxicity and good clinical application prospect.
