本发明涉及嘧啶类化合物或其盐在制备用于预防和/或治疗与FLT3相关的疾病或障碍的药物中的应用。
背景技术
恶性肿瘤是严重危害人类健康的重大疾病之一,国家肿瘤登记中心日前发布的《2013年中国肿瘤登记年报》显示:中国每年新发癌症病例高达309万,按照平均寿命74岁计算,一生患癌症的几率高达22%,癌症已成为一种常见病。中国每5个死亡者中就有一个死于癌症,占全世界癌症死亡人数的1/4,癌症已成为继心血管疾病后的第二大杀手。虽然近年来临床上在肿瘤的化疗、放疗、分子靶向治疗等治疗手段方面取得了长足进步,但肿瘤长期生存率并未得到明显提高,研发新的抗肿瘤药物仍然是目前医药研发的热点。
近年来,蛋白激酶抑制剂一直都是抗肿瘤药物研发的热点领域,有许多小分子激酶抑制剂如伊马替尼、索拉非尼和舒尼替尼已经上市,此外还有大量的小分子激酶抑制剂处于临床研究阶段。FMS样酪氨酸激酶3(Fms-like tyrosine kinase,FLT3)又名胎肝激酶-2(Fetal Liver Kinase-2,FLK2)和干细胞激酶-1(Stem Cell Kinase-1,STK1),是一种第三类受体酪氨酸激酶。FLT3是受体型酪氨酸激酶,其天然配体包括血小板源性 生长因子(Platelet Derived Growth Factor,PDGF)、群落刺激因子1(Colony Stimulating Factor 1,CSF-1)和Kit激酶配体(Kit ligand,KL),配体与FLT3结合后,使FLT3发生二聚化,同时其胞内的酪氨酸激酶域发生磷酸化而被活化,从而启动下游的磷脂酰肌醇-3-羟激酶(Phosphatidyl Inositol3-Kinase,PI3K)通路和Ras通路,促进细胞的增殖分裂,同时促进抗凋亡蛋白BCL2家族蛋白BAD(BCL2Associated Death promoter)的活化,从而抑制细胞凋亡。
FLT3与包括SH2包含蛋白(SH2-containing sequence proteins,SHCs)、含SH2结构域的肌醇磷酸酶(SH2-domain-containing InositolPhosphatase,SHIP)、包含SH2结构域的酪氨酸蛋白的磷酸酶(SH2-domain-containing Protein Tyrosine Phosphatase-2,SHP2)、Cbl和GRB2结合蛋白2(GRB2-associated binder,GAB2)在内的多个蛋白的相互作用可以调节PI3K的活性。活化的PI3K会激活包括3-磷酸肌醇依赖的激酶-1(3-Phosphoinositide-Dependent Kinase-1,PDK1)、蛋白激酶B(Protein Kinase B,Akt1/PKB)和雷帕霉素靶蛋白(mammalian Target of Rapamycin,mTOR)在内的下游信号,进而激活核糖体S6K蛋白激酶(S6K)、抑制真核细胞始动因4E结合蛋白1(4E-Binding Protein 1,4E-BP1),最终启动关键基因的转录和翻译。FLT3同时能够介导Ras通路,FLT3激活后,联合生长因子受体结合蛋白2(Growth Factor Receptor Bound 2,GRB2)通过SHC活化Ras,进而激活包括Raf、丝裂原激活的蛋白激酶(MAPK/ERK Kinases,MEK)、p38、细胞外信号调节激酶1/2(Extracellular Signal-Regulated Kinase 1/2,ERK1/2)和核糖体S6蛋白激酶(Ribosomal S6Kinase,RSK)在内的下游信号,而这些下游信号又能激活环磷酸腺苷反应元件结合蛋白(cAMP Response Element Binding protein,CREB)、Elk(又称促红细胞生成素产生肝细胞受体B1,Erythropoietin-Producing Hepatocellular receptor B1,EPH receptor B1)和信号传导与转录激活子(Signal Transducer and Activator of Transcription,STAT),最终转录翻译出细胞增殖中需要的蛋白,促进多能干细胞、早期祖细胞和不成熟的淋巴 细胞增殖。
FLT3与多种疾病相关,如肿瘤、癌症和血液恶性肿瘤(Ansari-Lari,Ali.FLT3mutations in myeloid sarcoma.British Journal of Haematology.126(6):785-91)。FLT3作为抗肿瘤药物研究开发的靶点,吸引了学术界特别是工业界的广泛兴趣。现已发现许多结构各异的FLT3抑制剂,其中4个抑制剂已经获准上市,更多的候选化合物正处于临床试验阶段。目前,已上市的抑制剂主要用于各种肿瘤的治疗。FLT3抑制剂作为抗肿瘤药物,临床疗效明显,副作用可控,因而正在获得越来越广泛的应用。在4个上市药物中,索拉非尼(2005年上市)和舒尼替尼(2006年上市)在2013年的销售额分别为:10亿2300万美元和12亿400万美元,双双超过10亿美元。而2013上市的帕纳替尼第一年的销售额就达到了4520万美元。卡博替尼于2013年上市,第一年的销售达到1500万美元。可见FLT3抑制剂作为抗肿瘤药物,其销售额均前景乐观。

实施例11对人MV-4-11裸小鼠皮下移植瘤的疗效
供试品配制:均用5%无水乙醇+5%Cremophor EL+90%生理盐水配制。
实验动物:BALB/cA-nude裸小鼠,6-7周,雌性♀,购自上海灵畅生物科技有限公司。生产许可证号:SC×K(沪)2013-0018;动物合格证号2013001810589。饲养环境:SPF级。
实验步骤:裸小鼠皮下接种人急性单核细胞白血病MV-4-11细胞,待肿瘤生长至80-150mm3后,将动物随机分组,每组6只。给药剂量15mg/kg,腹腔注射,每天3次,给药21天。测瘤体积,称鼠重,记录数据。
肿瘤体积(V)计算公式为:
V=1/2×a×b2
其中,a、b分别表示长、宽。
T/C(%)=(T-T0)/(C-C0)×100
其中,T、C为实验结束时的肿瘤体积;T0、C0为实验开始时的肿瘤体积。
计算抑瘤率,实验结果如表4所示。
