长春瑞滨衍生物、其药物组合物及其制备方法和用途
技术领域
本发明涉及一种可治疗肿瘤的长春瑞滨衍生物、其药物组合物及其制备方法和用途。
背景技术
恶性肿瘤是继心血管之后成为威胁人类健康的最主要疾病。在世界范围内,由该疾病导致的死亡人数占总死亡人数的15%,而这一比率在发展中国家达到了25%,目前平均每年近800万人死于恶性肿瘤。因此,面对日益严峻的恶性肿瘤危机,世界各国都在努力改善全球癌症治疗尤其是发展中国家肿瘤治疗现状。
长春碱类化合物是二聚吲哚类生物碱,是一类重要的细胞周期特异性抗肿瘤药物,主要用于治疗何杰金氏病、乳腺癌、非小细胞性肺癌等。长春碱类药物可干扰细胞周期的有丝分裂阶段(M期),从而抑制细胞的分裂和增殖。其细胞毒性是通过与微管蛋白的结合实现的,它们在微管蛋白二聚体上有共同的结合位点,可抑制微管聚合,妨碍纺锤体微管的形成,从而使分裂于中期停止,阻止癌细胞分裂增殖。
长春碱(vinblastine,VLB)和长春新碱(vincristine,VCR)最早是从夹竹桃科长春花(CatharanthusroseusL.G.Don)植物中分离得到的双吲哚生物碱类的抗肿瘤药物,在临床上已经被广泛使用了40多年。由于它们结构的微小变化导致其毒性以及治疗瘤谱的极大不同,因此,人们致力于通过结构修饰以期发现广谱、高效、低毒的新长春碱类抗肿瘤药物。到目前为止,相继已有3个半合成的长春碱类药物被开发上市:长春地辛、长春瑞滨和长春氟宁。
由法国PierreFabre实验室开发的第三代长春碱类药物长春瑞滨(Vinorelbine),已成为临床上治疗非小细胞肺癌的一线药物(S.Cros,elal.,SeminarsinOncology,1989,16:15-20。),其与长春碱、长春新碱、长春地辛相比,具有抗瘤谱广、毒副作用小和化学稳定性高等优点。除了用于非小细胞肺癌,长春瑞滨对转移性乳腺癌及难治性淋巴瘤、卵巢癌、头颈部肿瘤等肿瘤也显示出治疗前景。
CN200710036923.2公开了一种长春瑞滨新衍生物,该衍生物具有9元环的结构式,具有抗癌的作用,但9元环的结构不够稳定。该申请中还公开了以文朵灵为起始原料,合成式(Ⅱ)和式(Ⅱ’)所示的关键中间体。
虽然长春瑞滨的开发取得很大成功,但依然存在很大不足,例如骨髓抑制毒性较大、静脉注射刺激性大、口服生物利用度不高、肿瘤耐药性的出现。另外,药代动力学特性及抗瘤谱也有待进一步改进提高。由于长春碱类药物结构上的微小变化,会引起药物与微管的亲和力、药物在体内的吸收和代谢过程、耐药性、毒性以及瘤谱的巨大差异。因此仍在不断开发设计新型化合物以优化和改进治疗效果。
发明内容
因此,本发明的目的之一是提供一种新的长春瑞滨衍生物或其可药用的盐。所述长春瑞滨衍生物不但具有类似或更优于长春瑞滨的药物特性,而且具有更好的稳定性,在在提高抗肿瘤选择性、优化药物特性、扩展抗肿瘤谱等方面具有重要意义和开发前景。
本发明的第二个目的是提供一种以上述长春瑞宾衍生物或其可药用的盐为活性成分的药物组合物。

试验实施例
试验实施例1本发明化合物的体外抗肿瘤活性实验
试剂材料:
细胞株:A549人非小细胞肺癌细胞株(购自ATCC)
阳性对照药:长春瑞滨酒石酸盐(按常规方法配制);纯度由HPLC-UV检测98%以上,结构由NMR确证。受试化合物和阳性对照物以生理盐水稀释,浓度梯度为10-4M、10-5M、10-6M、10-7M、10-8M。
实验方法:
采用MTS方法:化合物对细胞作用一段时间后,采用MTS方法检测细胞存活状态。原理与MTT法的原理是一致的,区别是MTS检测试剂盒(Promega,cat#G5421)中的成分与细胞作用后,形成的是可溶性的甲賛,在490nm下有最大吸收。这种方法的优势在于并不杀死细胞,在不去除培养基的状况下能时时进行检测。通过检测490nm下的吸光度值计算出细胞存活率。
实验步骤:

试验实施例2对A549裸鼠移植瘤模型的体内抗肿瘤活性评价
试剂材料:
细胞株:A549人非小细胞肺癌细胞株(购自ATCC)。
试验动物:Balb/C裸鼠,雄性,6周龄,购自北京华阜康生物科技股份有限公司。饲养于SPF环境,温度20~25℃,相对湿度40~70%,12:12h光暗照明;自由饮水及采食。长春瑞滨及受试药物(B-08,B-19)均采用合成方法制备而得,纯度>98%。
实验方法:
A549细胞在体外培养扩增,收取对数生长期细胞,重悬于无血清F-12K培养液中接种于裸鼠右前肢腋窝皮下;22天后,肿瘤生长至约260mm3,根据肿瘤大小采用随机区组法将荷瘤鼠分组(6只/组),包括溶剂对照组,阳性对照长春瑞滨(NVB)组,及受试样品组。静脉注射(iv)给药,给药一次,观测肿瘤生长情况。
测定结果:
B-08和B-19对A549裸鼠移植瘤均显示一定抑制作用,在相同剂量,B-19的抗肿瘤活性高于NVB。
试验实施例3对MDA-MB-231裸鼠移植瘤模型的体内抗肿瘤活性评价
试剂材料:
细胞株:人乳腺癌MDA-MB-231,来自中国科学院细胞库。
试验动物:Balb/C裸鼠,雌性,6周龄,购自北京华阜康生物科技股份有限公司。饲养于SPF环境,温度20~25℃,相对湿度40~70%,12:12h光暗照明;自由饮水及采食。长春瑞滨及受试药物(B-14)均采用合成方法制备而得,纯度>98%。
实验方法:
MDA-MB-231细胞在体外培养扩增,收取对数生长期细胞,重悬于DMEM无血清培养液后接种于裸鼠右前肢腋窝皮下;14天后,肿瘤生长至约250mm3;根据肿瘤大小采用随机区组法将荷瘤鼠分为组,溶剂对照组尾静脉注射生理盐水注射液,每周1次;阳性对照NVB和受试药物B-14尾静脉注射给药(iv),每周1次,连续21天,观测肿瘤生长情况。
测定结果:
B-14对MDA-MB-231裸鼠移植瘤显示一定抑制作用,在相同剂量,NVB抗肿瘤活性不明显。
试验实施例4本发明化合物的稳定性试验
样品制备:
精密称取中国专利申请CN200710036923.2中公开的如下结构式所示化合物7、34、38和43的酒石酸盐(以上化合物按照CN200710036923.2中公开的方法事先制备),以及以上制备的本发明化合物A-01、B-07、B-17和B-19的酒石酸盐各10mg,分别置10ml量瓶中,加蒸馏水溶解,加流动相至刻度,摇匀,即得(每1ml中含各待测化合物的酒石酸盐各1mg)。配置好的样品放在避光的25°C的容器里储存。
测定方法:
分别精密吸取以上制备的溶液各10μl,检测0、6小时样品峰面积的变化考察样品的稳定性。样品在0小时的纯度设为100%,6小时的样品峰面积除以0小时的样品峰面积为样品在6小时的纯度。
色谱条件:
以十八烷基硅烷键合硅胶为填充剂;以乙腈-水(50mMKH2PO4+5mM十二烷基磺酸钠)(50:50)为流动相;流速为1ml/min;检测波长266nm;柱温为40°C。
表2、CN200710036923.2中公开的化合物与本发明化合物酒石酸盐在水溶液中的稳定性结果对比
化合物 6小时后的纯度 化合物 6小时后的纯度
7 80.23% A-01 99.34%
34 83.62% B-07 99.45%
38 85.34% B-17 99.67%
43 80.69% B-19 99.81%
以上结果可见本发明的化合物(即长春瑞宾衍生物A-02、B-07、B-17、B-19)的酒石酸盐在水溶液中的化学稳定性全部大大高于具有对应结构的CN200710036923.2中公开长春瑞宾衍生物,在药物开发中具有更广阔的应用前景。
