Description

哒嗪酮类化合物在制备抗肿瘤药物中的用途
技术领域
本发明属于药物学领域,具体涉及以6-(3-(三氟甲基)苯基)哒嗪-3(2H)-酮为母核的哒嗪酮类化合物的用途,上述化合物具有显著的抗肿瘤活性,尤其是对肝癌的抑制活性。
背景技术
哒嗪酮类化合物显示了广泛的生物活性,比如作为抗抑郁药、血管舒张药、强心药、止痛/抗炎药、抗高血压药及在农业上作为杀螨剂、除草剂,其它还有作为乙酰胆碱酯酶、醛糖还原酶、单胺氧化酶、CDKs、COX-2、P38MAP激酶的抑制剂等。也有部分哒嗪酮类化合物显示了一定的抗肿瘤活性。作为GSK-3β抑制剂,专利文献US2007/0072866A1报道了一类哒嗪酮化合物,其结构式为
Figure G200910127196XD00011
可治疗代谢疾病或神经退化疾病及相关疾病。专利文献CN200380105057限定其中A为C(O)NHR和NHC(O)R;US2007/0072866A1中为杂环取代。
专利文献WO03/059891及WO2005/007632公开了用于治疗因P38MAP激酶活性和/或TNF活性失调引起或加重的疾病或病症。上述专利文献中的哒嗪酮类化合物,结构式为可用于治疗炎性疾病、糖尿病、阿耳茨海默氏病或癌症。其所述的哒嗪酮类化合物的范围几乎将所有取代基覆盖,但实际上其R4主要为芳基取代,R1为主要为卤素,R2为各类较多类型取代,R3仅为H取代。
与本申请最为相关的文献为抗肿瘤活性专利文献,为Aventis公司申请的一种哒嗪酮衍生物为CDK2抑制剂,其专利文献号为WO2004/046130,WO2005085231,WO2005/111019和US2007/0173503。其结构为
Figure G200910127196XD00021
其中X为C(O)NHR,NHC(O)R及含氮杂环,R2为H,R3为芳环及杂环。
另外,专利文献WO2006/124874中RAF激酶抑制剂可用于抗肿瘤及欧洲专利文献0655223中抗肿瘤抑制剂也提到哒嗪酮类化合物,但与本申请的所覆盖的化合物截然不同。
此外其他文献中还描述另外很多哒嗪酮衍生物,它们与本申请化合物的不同之处在于取代模式、部分和/或6-位芳环的选择,或者化合物应用范围的不同。
众所周知,肝癌是第五大常见的男性肿瘤疾病,是第八大常见的女性肿瘤疾病。在2007年,估算的新增肝癌患者将有80%在发展中国家中产生,仅我国就占了总数的55%。而在发展中国家,59%的肝癌可归咎于HBV,33%的肝癌可归咎于HCV。尤其近年来,由于亚太国家乙肝病毒感染肆虐,肝癌发病率不断上升,对治疗肝癌药物有巨大的市场需求。

实施例13:体内抗肿瘤作用
实验方法:BALB/cA-nude裸小鼠,6-7周,♀,购自上海斯莱克实验动物有限责任公司。合格证号:SCXK(沪)2007-0005。饲养环境:SPF级。YHHU-45、YHHU-258及对照药物索拉非尼(sorafenib)均用含0.1%Tween-80的0.5%CMC配成所需浓度。裸小鼠皮下接种人肝癌Bel-7402细胞,待肿瘤生长至100-300mm3后,将动物随机分组(d0)。给药剂量和给药方案见图注。每周测2-3次瘤体积,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)。结果见图1和图2。
图1为YHHU-45对人肝癌Bel-7402裸小鼠移植瘤的疗效。裸小鼠皮下接种Bel-7402细胞,待肿瘤长到160mm3左右开始给药(100mg/kg),连续灌胃16天,并测量肿瘤大小。空白对照n=12;YHHU-45:n=5。相对肿瘤体积(RTV):最后1天肿瘤体积/开始给药时的肿瘤体积。
图2为YHHU-258对人肝癌Bel-7402裸小鼠移植瘤的疗效。裸小鼠皮下接种Bel-7402细胞,待肿瘤长到210mm3左右开始给药(100mg/kg),连续灌胃9天后停药,但持续观察19天,并测量肿瘤大小。空白对照n=10;YHHU-258:n=5。相对肿瘤体积(RTV):最后1天肿瘤体积/开始给药时的肿瘤体积。
可以看出:YHHU-45、YHHU-258均显著抑制肝癌Bel-7402裸小鼠移植瘤的生长;YHHU-258给药5天后,引起所有肿瘤消退,且未见复发。
