- the effective dose is about one-tenth of the 5-fluorouracil LD50 value (230 mg/kg), which has good safety.
- Tests and calculations have shown that a wider range of 5-500 mg / kg is also effective, depending on the type of cancer or tumor, the severity of the disease, 25mg / kg and 50mg / kg is only a better choice.
- Kunming mice (body weight 17-22g, male and female) were randomly divided into groups according to their body weight. The experiment was divided into 10 dose groups with a maximum dose of 1500mg/kg and a dose of 0.9.

- the 5-fluorouracil derivative of the present invention contains a stilbene and a diphenylethane fragment in the molecular structure, and the fragment functions as the same tubulin aggregation inhibitor as CA4. Therefore, the 5-fluorouracil derivative of the present invention can be used as a tubulin aggregation inhibitor, and can also be used for the preparation of a tubulin aggregation inhibitor.
- the 5-fluorouracil derivative of the present invention can interfere with tubulin aggregation and inhibit the formation of tumor blood vessels, so it can also be used as an anti-tumor vascular disrupting agent or as an anti-tumor vascular disrupting agent. It is used in the preparation of drugs that have vascular targeting effects on various tumors.

Description
本发明属于药物化学领域,尤其涉及抗肿瘤化合物、该化合物的制备方法和医药用途。
1971年Folkman最早提出血管新生理论,认为肿瘤的血管系统在肿瘤生长、发展和转移过程中起着重要作用,抑制肿瘤血管生成,可导致肿瘤细胞因缺血、缺氧而部分死亡,从而延缓肿瘤生长和抑制肿瘤转移(Folkman J.er al.,J.Med 1971,285,1182-1186)。药理研究证实肿瘤的生长必须依赖血管的生成,这为肿瘤治疗提供了一个新靶点,肿瘤血管靶向药物的研发已经成为抗肿瘤药物的研究热点。上世纪80年代美国科学家报道从南非的一种风车子属植物(Combretum caffrum)树干中提取分离出一系列具有抗肿瘤活性的二苯乙烯类化合物(Srivastava V.et al.,Bioorg.Med.Chem.2005,13,5892-5908),研究表明,该类不仅能阻断肿瘤血管生成也能抑制微管蛋白的聚合,其对微管蛋白的作用微点与秋水仙素类似,该类化合物中中以CombretastatinA-4(简称:CA4)的活性最好。CA4的脂溶性强而水溶解性不好限制了将其直接作为药物进行开发研究,制药公司Oxigene将CA4做成水溶性的磷酸酯二钠盐(CombretastatinA-4 phosphate,简称:CA4P)的前药进行开发,目前该化合物已经进入Ⅲ期临床研究。
基于CA4化学结构和抗肿瘤作用机制的结构修饰研究是近年来抗肿瘤药物研究的热点。CA4类化合物的结构简单,与其它微管蛋白抑制剂一样具有共同的结构特征,即二芳基桥,其中有3个甲氧基的环为A环,另一个为B环(Medarde M.et al.,Bioorg.Med.Chem.Lett.,1999,9,2303-2308)。结构修饰的一个研究重点是对两环之间的连接片段上的修饰或替换,研究表明顺式双键二苯乙烯化合的活性明显高于反式双键化合物(Cushman M.et al.,J.Med.Chem.1991,34,2579-2588;Nam N.H.,et al.Bioorg.Med.Lett.,2002,12,1955-1958),在双键上引入取代基的报道较多,但所合成的衍生物的活性不高(Hadfield J.A.,et al.,Eur.J.Med.Chem.,2005,40,529-541;Pinney K.G.et al.,Bioorg.Med.Chem.,2000,8,2417-2425),将烯键用饱和碳链替换,活性实验结果表明2个碳数的化合物活性得到保留或提高,而其他化合物基本活性丧失(Getahum Z.et al.,J.Med.Chem.1992,35,1058-1067)。
目前国内外同时在开展研究的该类药物只有二苯乙烯类化合物CA4进入临床研究,发明专利申请“乙氧基康普立停及其前药的制备和用途”(国际公布号WO2008/031333A1)公开了CA4的B芳环4’-位烷氧基是个活性作用位点,把二苯乙烯B芳环4’-位原有的甲基改造成乙基,和3’-位的羟基、氨基等基团能形成活性靶点,可提高其对肿瘤血管靶向活性。我们通过研究发现,将二苯乙烯类化合物的双键氢化后形成的二苯乙烷类衍生物3,4,5-三甲氧基-3’-羟基-4’-烷氧
基二苯乙烷的4’-位-烷氧基和3’-位羟基同样具有协同作用,且与CA4相比其抗肿瘤效果有显著提高(吴范宏等,一种乙氧基二苯乙烷衍生物及其制备方法和用途,公布号US2012/0046492A1;一种3,4,5-三甲氧基-3’-羟基-4’-烷氧基二苯乙烷的制备方法,公布号CN103539642)。将双键改造成饱和键后,由于不存在顺反式异构体的变化,相关理化性质比CA4更稳定,化合物的制备工艺更加简便,合成收率显著提高,而原料损耗和单位合成成本大大降低。
5-氟尿嘧啶(简称:5-FU)是传统的临床常用的抗肿瘤药物,作为一种重要的水溶性抗代谢类药物,由于稳定的C-F键结构及酸性的增强能更牢固地与酶结合,可替代肿瘤核酸的重要前体尿嘧啶掺入RNA,也可阻断尿嘧啶5位甲基化而抑制DNA合成,从而发挥抗肿瘤作用。其临床广泛应用于乳腺癌、大肠癌和胃癌。但是由于其首过代谢显著,亲脂性低,故其口服吸收不完全,直肠给药吸收更差,生物利用度低,影响抗肿瘤疗效,且其治疗剂量与中毒剂量接近。为了克服以上缺点,以及临床应用时存在的呕吐腹泻、脱发、白细胞与血小板下降、中枢神经毒性等副作用,人们对其进行了大量研究,也已经开发出一些疗效更好、毒副作用小的衍生物,主要是提升了5-氟尿嘧啶的生物活性、选择性、脂溶性、吸收性能和低毒性,其中包括有氟尿苷和替加氟这两种广泛用于临床的典型5-氟尿嘧啶衍生物。
新药开发中,拼合原理是最常用也是最重要的方法之一。拼合方法的应用主要是研制双重作用的药物,这种双重作用包括与不同的受体作用、与一个受体的两个不同的结合位点作用、与两个不同的酶的作用或与一个酶一个受体的作用。将不同作用靶点的抗肿瘤药物拼合起来很有可能获得活性更高、毒副作用更低、耐药性更好的新型抗肿瘤药物。利用拼合原理将5-FU和其它抗肿瘤药物进行拼接偶联一直是药物研究领域中的一大研究热点。Menger将5-FU和阿糖胞苷拼接得到一种新的5-FU衍生物,在高pH值下仍然稳定存在(Menger,F.M.;Rourk,M.J.Synthesis and Reactivity of 5-Fluorouracil/Cytarabine Mutual Prodrugs.J.Org.Chem.,1997,62,9083.)。鬼臼毒素具有抗病毒和抗肿瘤活性,用于治疗多种肿瘤,但是由于其具有典型的副作用限制了它的临床应用,Chen制备了一系列鬼臼毒素和5-FU的拼接产物,SAR研究表明使用不同的氨基酸对活性有很大影响,氨基酸支链的羟基会使活性显著降低,而烷基连结基的增长并不会对活性造成明显影响(Chen,S.W.;Xiang,R.;Liu,J.;Tian,X.Synthesis and biological evaluation of novel conjugates of podophyllotoxin and 5-FU as antineoplastic agents.[J].Bioorg.Med.Chem.,2009,17,3111.)。喜树碱是以拓扑异构酶I为目标的具有很高抗肿瘤活性的细胞毒素生物碱,但是由于它的极低水溶性和不稳定的内酯结构限制了其临床应用,Zhou等使用二肽为连结基制备了喜树碱和5-FU的拼接产物,提高了肿瘤选择性和安全性(Zhou,W.M.;He,R.R.;Ye,J.T.;Zhang,N.;Liu,D.Y.Synthesis and Biological Evaluation of New 5-Fluorouracil-Substituted Ampelopsin Derivatives[J].Molecules.,2010,15,2114.)。
发明内容
在抗癌、抗肿瘤药研究开发领域,研究人员都认识到二苯乙烯、二苯乙烷类化合物和5-氟尿嘧啶对肿瘤都具有良好的治疗效果,但是它们各自的缺陷也都客观存在。
通过比较它们的抗肿瘤效果的优缺点,我们发现它们存在互补的可能性。二苯乙烯/乙烷类化合物与5-FU抗肿瘤作用机制不同,但两者均具有良好的体外抗
肿瘤活性,在作用方式上具有良好的互补性,联合用药时也体现出更好的疗效。我们创造性的通过拼合原理将二苯乙烯/乙烷类化合物与5-氟尿嘧啶通过酰胺键拼合形成结构新颖的抗肿瘤药物分子,同时通过后续的生物活性测试发现该新化合物兼具两类抗肿瘤药物的优势,达到了协同增效目的,具有良好的应用开发前景。

发明的作用与效果
在生物活性测试实验中,以CA4和5-氟尿嘧啶为阳性对照药,将其与如本发明通式Ⅰ的两类抗肿瘤药拼接物一起用于Hela宫颈癌细胞株的体外增殖抑制活性评价(MTT法),在相同试验条件下5-氟尿嘧啶和CA4的IC50值分别为113.24和400nM,而所有拼接物的IC50值在70nM以下,其中活性最好的化合物对Hela宫颈癌细胞株的体外增殖抑制活性是5-氟尿嘧啶的4倍和CA4的14倍。
选取两个拼接物进一步考察了对其它4种肿瘤细胞株(MCG-803、HepG2、A549、MDA-MA-231)的体外抗肿瘤抑制活性。与阳性药CA4和5-氟尿嘧啶相比,拼接物的活性均有明显的提高,说明拼接后的产物在体内具有协同作用。
进一步分析,发现连结基L2上的烷基碳个数(n=1,2,3,4)对产物活性有一定影响,总体而言n=2时活性较佳。
选取2个体外活性较强的化合物,对MGC-803小鼠移植瘤的抑瘤率实验,口服给药50mg/kg时抑瘤率在80%以上,口服有效剂量为5-氟尿嘧啶LD50值(230mg/kg)的十分之一左右,具有较好的安全性,
5-氟尿嘧啶为抗代谢类抗肿瘤药,抗肿瘤谱广,骨髓抑制和严重的肠胃道反应等毒副作用/不良反应降低了患者对治疗的耐受性,该类化合物水溶性高而脂溶性差。二苯乙烯/烷类化合物作为一类微管蛋白抑制剂,具有肿瘤血管靶向性,其脂溶性高而水溶性差,本发明将两种不同作用机理的抗肿瘤药物以化学键的形式拼接在一起,可以改善各自的药学性质,提高二苯乙烯/烷类化合物的抗肿瘤活性和口服生物利用度,此外,通过二苯乙烯/烷类片段的血管靶向作用可将5-氟尿嘧啶导向肿瘤细胞,从而降低5-氟尿嘧啶的毒副作用。
因此,本发明提供的将两类抗肿瘤药拼接所得的新结构化合物Ⅰ兼具两类抗肿瘤药物的抗肿瘤作用,而毒副作用较5-氟尿嘧啶的毒副作用小。

4.3、实验结果分析
由表4的实验结果可知,测试的化合物Ii、Ij、Ik、Il的急性半数致死浓度都在1000mg/kg以上,毒性很低,也就是说本发明的5-氟尿嘧啶衍生物(二苯乙烯及二苯乙烷类片段与5-FU孪药拼接的化合物)毒性很低(较5-FU低,而与CA4相当),具有较好的安全性。
生物活性测试实验总结
5-氟尿嘧啶为抗代谢类抗肿瘤药,抗肿瘤谱广,骨髓抑制和严重的肠胃道反应等毒副作用/不良反应降低了患者对治疗的耐受性,该类化合物水溶性高而脂溶性差。二苯乙烯/烷类化合物作为一类微管蛋白抑制剂,具有肿瘤血管靶向性,其脂溶性高而水溶性差。
本发明将两种不同作用机理的抗肿瘤药物以化学键的形式创造性地拼接在一起,并设计新颖的合成路线来合成这类特定新颖结构(new structure)的化合物,并通过以上的生物活性测试:典型癌细胞株的体外活性,小鼠体内肿瘤抑制活性证明了本发明提出的5-氟尿嘧啶衍生物兼具两类抗肿瘤药物的优势,起到了协同增效目的。因而该类化合物可以改善两类抗肿瘤药物各自的药学性质,提高二苯乙烯/烷类化合物的抗肿瘤活性和口服生物利用度。此外,通过二苯乙烯/烷类片段的血管靶向作用可将5-氟尿嘧啶导向肿瘤细胞,从而降低5-氟尿嘧啶的毒副作用。
作为一种本领域技术人员公知的知识,本发明的5-氟尿嘧啶衍生物的分子结构中含有二苯乙烯及二苯乙烷类片段,该片段起到了与CA4相同的微管蛋白聚集抑制剂用途,因此本发明的5-氟尿嘧啶衍生物必然可以作为微管蛋白聚集抑制剂,也可以用于制备微管蛋白聚集抑制剂类药物。
正如在背景技术中所述,本发明的5-氟尿嘧啶衍生物可以干扰微管蛋白聚集从而抑制肿瘤血管的形成,所以其也必然可以作为抗肿瘤血管破坏剂,也可以作为抗肿瘤血管破坏剂,用于在制备对各种肿瘤具有血管靶向作用的药物。
