  • the present invention belongs to the field of natural medicines and medicinal chemistry, and relates to novel tetrandrine derivatives, particularly 5-position carbon-substituted tetrandrine derivatives, and methods for preparing the same, compositions comprising the same, and Use in the preparation of anti-tumor drugs. Background technique
  • Tetradrine also known as tetrandrine, chemical formula (6,6,7,12-tetramethoxy-2,2,dimethyl berbamine), is the root of Chinese herbal medicine A bisbenzylisoquinoline alkaloid extracted from the block. Tetrandrine inhibits central nervous system and has anti-inflammatory, analgesic and antipyretic effects. Because of its direct expansion of peripheral blood vessels, P-bar pressure is significant and long-lasting, so it can be used for rheumatic pain, arthritis, neuralgia, and muscle. Pain and various types of high blood pressure.
  • Tetrandrine has a negative inotropic effect on the heart, negative frequency and negative conduction, and reduces myocardial oxygen consumption, which can prolong myocardial refractory period and atrioventricular conduction, increase myocardial blood flow, and reduce total peripheral circumference.
  • the vascular resistance causes the blood pressure to drop, and the non-reflective heart rate increases when the P-bar pressure is applied. Since the after-load is reduced, the cardiac output can be increased.
  • ⁇ tetrandrine has a proliferation inhibitory effect on cervical cancer HeLa cells.
  • the MTT assay was used to inhibit the effect. Apoptosis was detected by flow cytometry and laser confocal microscopy. It was confirmed that tetrandrine has a proliferation inhibitory effect on cervical cancer HeLa cells in a time- and concentration-dependent manner.
  • Tetrandrine inhibits the proliferation of liver cancer cells. After the action of tetrandrine on hepatocellular carcinoma cells, it caused the production of reactive oxygen species within 2 hours. With the increase of dose, the production of ROS increased significantly, suggesting that tetrandrine may produce reactive oxygen species by interfering with the function of mitochondria. Cellular lipid peroxidation, damage to DNA molecules or regulation of apoptosis-related genes inhibits proliferation of liver cancer cells. (Jing Xubin et al., Experimental study on the oxidative damage of hepatoma cells induced by tetrandrine, Clinical Journal of Clinical Hepatology, 2002, 18 (6), 366).
  • tetrandrine has a significant growth inhibitory effect on human neuroblastoma TGW. Studies have shown that as the dose increases, the inhibitory effect increases gradually, and the inhibitory effect is also enhanced with the prolongation of the action time, with good dose-time correlation (Li Yusong et al., Clinical Pediatrics Journal, tetrandrine-induced neuroblasts) A study on the risk of TDW apoptosis in tumor strains, 2006, 24 (6), 512).
  • the tetrandrine has the above-mentioned interference with tumor cells, inhibits its proliferation and proliferation, induces apoptosis, and increases tumor growth, and also regulates P-glycoprotein-mediated drug resistance of multi-drug resistant cells and down-regulates the drug resistance gene mdrl mRNA. expression.
  • tetrandrine can promote the cancer cells after irradiation to enter the M phase from the G2 phase, reducing the repair time of radiotherapy cell damage, thereby achieving the purpose of radiosensitization.
  • the experiment selected low-concentration Hsweepingjia to study the radiosensitization effect, and found that the survival fraction of TE1 cells decreased exponentially with the increase of radiation dose, and the radiation sensitization reached 0.52 at 0.5 g/mL drug concentration, indicating that tetrandrine was cultured in vitro.

本发明属于天然药物及药物化学领域, 并涉及新型汉防己甲素衍 生物, 特别是 5-位碳取代的汉防己甲素衍生物, 及制备这些化合物的方 法、 包含该化合物的组合物及其在制备抗肿瘤药物中的用途。 背景技术
汉防己甲素 (tetrandrine, TTD), 又叫粉防己碱, 化学式( 6,6,, 7,12- 四甲氧基 -2,2,二甲基小檗胺) , 是从中草药防己的根块中提取的双苄基 异喹啉类生物碱。 汉防己甲素对中枢神经有抑制作用, 有消炎、 镇痛、 退热作用, 由于其直接扩张周围血管, P条压作用显著而持久, 因此可用 于风湿性疼痛、 关节炎、 神经痛、 肌肉痛及各种类型的高血压。 汉防己 甲素对心脏有负性肌力作用, 负性频率作用及负性传导作用, 并降低心 肌耗氧量, 可延长心肌的不应期和房室传导, 增加心肌血流量, 降低总 外周血管阻力, 使血压下降, P条压时无反射性心率增快, 由于后负荷降 低, 心输出量可增加。 这些作用均与其钙拮抗作用有关。 因此, 各国的 科学家对汉防己甲素及其衍生物和类似物进行了广泛的研究。 (季宇彬 等. 中药抗肿瘤有效成分药理与应用. 哈尔滨: 黑龙江科学技术出版社, 1995; Su, J.

^汉防己甲素对宫颈癌 HeLa细胞具有增殖抑制作用^ 研究采用 MTT法, 抑制作用。 通过流式细胞仪和激光共聚焦显微镜检测细胞凋亡情况。 实 验证明, 汉防己甲素对宫颈癌 HeLa细胞具有增殖抑制作用, 且呈时间、 浓度依赖性。 (朱克修等, 粉防己碱诱导宫颈癌细胞凋亡的定性定量研 究, 西安交通大学学报 (医学版), 2010, 31 (1), 102 ) 。
汉防己甲素能抑制肝癌细胞的增殖。 汉防己甲素作用于肝癌细胞 后,在 2小时内引起活性氧的产生, 随着剂量的增大, ROS产生明显增加, 提示汉防己甲素可能通过干扰细胞线粒体的功能而产生活性氧, 引起细 胞脂质过氧化、损伤 DNA分子或调节细胞凋亡相关基因而抑制肝癌细胞 的增殖。 (荆绪斌等, 汉防己甲素诱导肝癌细胞氧化损伤的实验研究, 临 床肝胆病杂志, 2002, 18 (6), 366)。
此外报道了体外汉防己甲素对人神经母细胞瘤 TGW有明显的生长 抑制作用。 研究显示, 随着剂量的增大, 抑制作用逐渐增强, 随着作用 时间的延长抑制作用也明显增强, 有着良好的剂量时间相关性(李巍松 等, 临床儿科杂志, 汉防己甲素诱导神经母细胞瘤株 TDW凋亡作用的 实险研究, 2006, 24 ( 6 ) , 512 ) 。
汉防己甲素具有上述干扰肿瘤细胞, 抑制其分裂增殖, 诱导细胞 凋亡, 肿瘤生长之外, 还能调节 P-糖蛋白介导的多要耐药细胞的耐药 性及下调耐药基因 mdrlmRNA表达。
有报道通过体外实验证明汉防己甲素用于耐药肺癌后, 耐药指数 有用阿霉素时的 5.43 降至 1.89, 说明汉防己甲素可以逆转 GLC-82/ADR耐药肺癌细胞对阿霉素的耐药。 此外, 有研究汉防己甲 素对人乳腺癌多药耐药株 MCF-7/ADR的逆转作用, 发现 2.5 μπιοΙ/L 的汉防己甲素可使阿霉素对耐药肿瘤的细胞毒性增加 20.4倍。证明汉 防己甲素对肿瘤 ADR逆转具有极大的潜在作用。 (徐萌等, 汉方己 甲素逆转肺癌化疗耐药和凋亡抗性的实 3 研究,实用癌症杂志, 2003, 18( 4 ) : 347; Fu, L. W, et al. The multidrug resistance of tumour cells was reversed by tetrandrine in vitro and in xenografts derived from human breast adenocarcinoma MCF-7/adr cells. European Journal of Cancer, 2002, 38(3):418 ) 。
此外, 临床实验还证实, 汉防己甲素可促进照射后的癌细胞由 G2期进入 M期, 减少放疗细胞损伤修复时间, 从而达到放疗增敏的 目的。
有报道通过对汉防己甲素增加乳腺癌细胞放射敏感性的实验研 究得出, 细胞受照射后诱导的周期阻滞与 p53基因功能有密切关系。 细胞在受到 γ射线照射后,其 Cyclin B l与 Cdc2蛋白表达水平明显降 低, 分裂指数也明显降低, 说明汉防己甲素是一种 G2期阻滞清除剂, 能显著增加 γ射线对人乳腺癌细胞的杀伤作用。 除此之外, 还有研究 发现汉防己甲素对人食管癌 TE1细胞立体实验具有放射增敏作用。实 验选取低浓度汉防己甲 来研究放射增敏效应,发现 TE1细胞存活分 数随辐射剂量增高呈指数型下降, 0.5 g/mL药物浓度时放射增敏最 大达 1.62, 说明汉防己甲素对体外培养的食管癌细胞具有一定放射增 敏作用, 其机制可能是通过增加周期蛋白 cyclin B l表达解除细胞 G2+M期阻滞。 (田庆中等, 汉方己甲素增加乳腺癌细胞放射敏感性 的实验研究, 东南大学学报, 2005, 24 ( 4 ) , 233 ; 于静萍等, 汉防 己甲素对体外培养食管癌细胞放射增敏作用的初步研究, 中华放射肿 瘤学杂志, 2010 , 19 ( 6 ) , 568 ) 。
