Definitions
- the present invention relates to a pharmaceutical composition and its use in the preparation of a medicament for treating cancer, in particular to a pharmaceutical composition comprising resveratrol and a resveratrol derivative and a Bcl-2 inhibitor and preparation thereof Use in the treatment of drugs for colon cancer, liver cancer, lung cancer, kidney cancer, gastric cancer, brain tumor, sarcoma, glioma, pancreatic cancer, ovarian cancer, breast cancer or prostate cancer.
- Background technique
- the World Health Organization survey shows that the global cancer situation is getting worse. The number of new patients will increase from the current 10 million to 15 million in the next 20 years, and the number of deaths due to cancer will increase from 6 million to 10 million per year.
- Primary liver cancer is a cancer that occurs in hepatocytes and intrahepatic bile duct epithelial cells. It is one of the most common malignant tumors in humans.
- the incidence of colon cancer is related to the environment, living habits, especially the way of eating. It is generally considered to be a high-fat diet and Insufficient cellulose is the main cause of the disease. With the improvement of living standards and the changes in diet structure, the incidence of colon cancer is increasing year by year.
- Glioma is a tumor originating from glial cells and occurring in the neuroectodermal layer. Its main features are diffuse infiltration and growth of tumor cells, no clear boundaries, infinite proliferation and high invasiveness. Despite the continuous improvement of neurosurgery skills, the precise positioning of radiotherapy and the continuous development of chemotherapy drugs in recent years, the recovery of glioma patients is still unsatisfactory, so the treatment of glioma is imminent.
- anti-tumor drugs such as alkylating agents, anti-metabolites, anti-tumor antibiotics, immunomodulators, etc.
- drugs are intolerant due to their toxicity.
- a large number of clinical practices have proved that Chinese medicine or combination of traditional Chinese and Western medicine can effectively treat malignant tumors, and at the same time can alleviate the side effects of radiotherapy and chemotherapy.
- it was found that some active natural products can effectively inhibit the growth of tumor cells and induce apoptosis.
- Many of the antibiotics and anti-tumor drugs currently in use are either directly derived from natural products or have been structurally modified. Therefore, the use of highly safe active natural products for clinical treatment of cancer will have broad prospects.
- molecular targeted therapy for a variety of evils Sexual tumors have received extensive attention and high attention.
- Molecular targeting drugs have high selectivity and wide language, and their safety is superior to cytotoxic chemotherapy drugs, which is a new direction in the field of cancer therapy.
- Resveratrol is a polyphenolic compound widely found in various plants such as grapes, Polygonum cuspidatum, and peanut. It is a natural phytoalexin and a green anticancer drug for cancer prevention and treatment. In vivo and in vivo, the resveratrol showed inhibition and even reversal of the three major stages of initiation, proliferation and development of most tumors. Its anti-tumor mechanism can inhibit tumor cell angiogenesis, inhibit cell cycle, promote tumor cell apoptosis, induce tumor cell differentiation, inhibit epoxidase and cytochrome P450 activity, interfere with related signal transduction pathways, and inhibit tumor angiogenesis. And so on.
- Apoptosis (programmed cell death) is a natural pathway by which the body removes abnormal or unwanted cells, which, if affected, can lead to various diseases such as cancer.
- Bc l-2 family proteins are important regulators of apoptosis, and Bc l-2 and Bc l-xL are overexpressed in various types of tumors, which are thought to be related to tumorigenesis, development and drug resistance. Therefore, the development of anti-apoptotic proteins against Bc l-2 and Bc l-xL has become a research hotspot in anti-tumor therapy in recent years.

Description
含有白藜芦醇及白藜芦醇类衍生物和 Bc l-2抑制剂的
药物组合物及其应用 技术领域
本发明涉及一种药物组合物及其在制备治疗癌症的药物中的应用, 具体涉及含有白藜芦醇及白藜芦醇类衍生物和 Bc l-2抑制剂的药物组合 物及其在制备治疗结肠癌、 肝癌、 肺癌、 肾癌、 胃癌、 脑瘤、 肉瘤、 神 经胶质瘤、 胰腺癌、 卵巢癌、 乳腺癌或前列腺癌的药物中的应用。 背景技术
世界卫生组织调查报告表明, 全球癌症状况日益严重, 今后 20年新 患者的人数将由目前的每年 1000万增加到 1500万, 因癌症而死亡的人 数也将由每年的 600万增加至 1000万。 原发性肝癌为发生在肝细胞与肝 内胆管上皮细胞的癌变, 是人类最常见的恶性肿瘤之一; 结肠癌的发病 与环境、 生活习惯, 尤其是饮食方式有关, 一般认为高脂肪饮食和纤维 素不足是主要发病原因, 随着生活水平的提高, 饮食结构的改变, 结肠 癌的发病率呈逐年上升趋势; 神经胶质瘤是起源于神经胶质细胞, 发生 于神经外胚层的肿瘤, 其主要特征是肿瘤细胞弥漫性浸润生长、 无明确 边界、 无限增殖并具有高度侵袭性。 尽管近年来神经外科手术技巧不断 完善、 放疗精确定位及化疗药物的不断研发, 但胶质瘤患者的愈后仍然 差强人意, 因此研究胶质瘤的治疗药物迫在眉睫。
目前已上市的抗肿瘤药物较多, 如烷化剂药物、 抗代谢药物、 抗肿 瘤抗生素、 免疫调节剂等, 但是大多药物由于毒性较大, 病人不耐受。 大量的临床实践证明, 中药或中西医结合能有效治疗恶性肿瘤, 同时能 减轻放化疗的毒副作用。 运用现代医学手段, 发现一些活性天然产物能 有效抑制肿瘤细胞的生长, 有诱导细胞凋亡的作用。 目前使用的众多抗 生素和抗肿瘤药物或直接来源于天然产物, 或经其结构改造而得。 因此, 安全性高的活性天然产物运用于临床以治疗癌症将具有广阔的前景。 随 着对肿瘤的发生发展的分子机制研究越来越清楚, 分子靶向治疗多种恶
性肿瘤受到了广泛的关注和高度重视。 分子靶向药物选择性高、 广语有 效, 其安全性优于细胞毒性化疗药物, 是目前肿瘤治疗领域发展的新方 向。
白藜芦醇(Resveratrol)是一种广泛存在于葡萄、 虎杖、 花生等多种 植物中的多酚化合物, 是一种天然的植物抗毒素, 是防治肿瘤的绿色抗 癌药物。 体内外实臉表明, 白藜芦醇对大多数肿瘤的起始、 增殖、 发展 这三个主要阶段均有抑制乃至逆转作用。 其抗肿瘤机制可以通过抗氧化、 阻滞细胞周期、 促进肿瘤细胞凋亡、 诱导肿瘤细胞分化、 抑制环氧化物 酶和细胞色素酶 P450的活性、 干扰相关信号转导通路、 抑制肿瘤血管生 成等发挥作用。
细胞凋亡 (程序细胞死亡)是机体清除异常或不需要的细胞的自然 途径, 若其受到影响则可能导致各种疾病如癌症的发生。 Bc l-2家族蛋白 是凋亡的重要调节剂, 其中 Bc l-2和 Bc l-xL在多种类型的肿瘤中过量表 达, 被认为可能与肿瘤的发生、 发展及耐药性产生有关, 故针对 Bc l-2 和 Bc l-xL 抗凋亡蛋白的药物开发成为近年来抗肿瘤治疗的研究热点。 ABT-263 和 ABT-737 是由美国雅培 ( Abbot t )制药开发的小分子 Bc l-2 抑制剂, 对多种肿瘤作用显著, 且可口服使用, 具有良好的应用前景。
随着肿瘤分子生物学的研究进展, 肿瘤分子靶向治疗已成为肿瘤研 究的热点, 在多种肿瘤的治疗中发挥了重要的作用。 然而, 大部分肿瘤 的生物学行为并非由单一信号传导通路所支配, 而是多个信号传导通路 共同起作用的, 中医药以其多基因多靶点的作用优势正日益受到关注。 因此合理的联合用药, 有单用药物不可比拟的优越性, 联合用药针对多 靶点进行靶向治疗将不仅旨在减少或延緩耐药性的出现、 降低毒性, 而 且通过多种药物对癌细胞杀伤的协同作用取得更好的疗效。 发明内容
