Description

新型抗肿瘤化合物、药物组合物及其应用 技术领域
本领域属于药物化学技术领域,具体涉及一种新型抗肿瘤化合物、药物组合物及其应用。
背景技术
目前,肿瘤仍是当今世界直接危及人类生命的一种最常见、最严重的疾病。肿瘤化疗取得了一定的进展,明显延长了患者的生存时间,但仍没有取得令人满意的疗效。近年来,人们对肿瘤学和肿瘤病灶部位分子水平研究的深入及许多新的治疗靶点的发现,为新型抗肿瘤药的开发提供了可能。随着对肿瘤细胞信号转导途径研究的不断深入,新型抗肿瘤药物的设计与研究越来越受到关注。
吉非替尼是由英国Astra-Zeneca公司开发的抗肿瘤药物,化学名为N-(3-氯-4-氟苯基)-7-甲氧基-6-(3-吗啉-4-丙氧基)喹唑啉-4-胺,结构式如式1所示。它可竞争细胞表面的表皮生长因子受体酪氨酸激酶(EGFR-TK)催化区域上Mg-ATP结合位点,属于EGFR-TK抑制剂并通过阻断细胞表面EGFR信号传导通路,阻碍肿瘤的生长、转移和血管生成,并可诱导肿瘤细胞的凋亡。目前已被FDA批准用于晚期非小细胞肺癌(NSCLC)患者经化疗后继续恶化的单用疗法,吉非替尼的上市为临床实体瘤治疗提供了一种全新的方法。
Figure PCTCN2014085756-appb-000001
瓦他拉尼是由诺华和先灵制药公司联合开发的用于治疗转移性结肠癌的药物,化学名为N-(4-氯苯基)-4-(4-吡啶甲基)-1-酞嗪胺,结构如式2所示。瓦他拉尼可有效地抑制血管内皮生长因子受体(VEGFR)家族成员、血小板衍生生长因子受体p(PDGFRl3)及c-Kit受体激酶,且口服生物利用度良好。体外激酶抑制试验显示,瓦他拉尼可抑制包括VEGFR.1/Fh-1.、VEGFR-2/KDR和VEGFR-3/FLT.4在内的所有已知的血管内皮生长因子受体家族成员。这些受体能够调控血管和***的生成以及肿瘤细胞的运动性,对肿瘤的发生起着重要作用。
在一系列抗肿瘤药物中,还有很多待深入研究的新化合物。文献(Synthesis and Cytotoxic Evaluation of Some New Phthalazinylpiperazine Derivatives.Arch.Pharm.Chem.Life Sci.2012,345,287–293)将瓦他拉尼分子结构引入哌嗪基,并将取代苯基通过乙酰基与之相连,制备得到一系列具有潜在抗肿瘤效果的化合物,其结构如式3所示:
