8-氮杂环取代色酮类衍生物及其制备方法与制药用途
技术领域
本发明涉及药物化学技术,具体涉及8-氮杂环取代色酮类衍生物及其制备方法与制药用途。
背景技术
聚腺苷二磷酸核糖聚合酶-1(PARP-1)是真核细胞中催化聚核糖化的细胞核酶,在介导碱基切除修复途径、修复细胞内异常DNA损伤和维持基因组完整性方面起重要作用。目前PARP-1对DNA单链损伤的修复机制已有较为透彻的研究:当DNA出现断裂损伤时,PARP-1以迅速识别并结合损伤缺口,激活聚腺苷二磷酸核糖(PAR)合成通路,进而修复损伤DNA。(Science 2016,353,45-50)多项研究显示,抑制PARP-1可使DNA修复功能降低,增强对多种肿瘤的化疗治疗效果。与此同时,细胞内修复异常DNA的系统并不是唯一的,正常情况下剔除或者抑制细胞PARP-1的活性,虽然可以在一定程度上导致细胞内单链DNA断裂的积聚,但此时细胞内的另外一套修复系统,即乳腺癌易感基因BRCA-1和BRCA-2介导的同源重组(HR)途径,可以修复双链DNA损伤,维持染色体的稳定。(Nature reviews.Molecular cellbiology 2017,18,610-621)乳腺癌是女性患者中最常见的癌症,患者的死亡率极高,研究发现,BRCA-1基因相关性乳腺癌患者约占乳腺恶性肿瘤病因的60%~80%。在修复异常DNA的细胞中,抑癌基因BRCA-1/2缺陷或突变的乳腺癌和卵巢癌细胞,对PARP-1抑制剂的敏感性是正常细胞的1000倍,抑制PARP-1的活性可靶向杀伤肿瘤细胞,(Nature 2005,434,917-21;European journal of medicinal chemistry 2018,145,389-403)导致合成致死,并且PARP-1与BRCA-1/2之间的这种合成致死作用得到了临床试验的验证。综上,PARP-1抑制剂是治疗肿瘤相关疾病的关键点,尤其是对于BRCA-1缺陷型肿瘤。
目前已经上市的PARP-1抑制剂奥拉帕(Olaparib)、瑞卡帕布樟脑磺酸盐(Rucaparib)无论是与化疗联合应用,还是单独用于BRCA缺陷型乳腺癌、卵巢癌都取得了良好效果。尽管PARP-1抑制剂在肿瘤治疗及化疗增敏方面具有重要意义,但目前仍存在一些不足,(Precision clinical medicine 2020,3,187-201)如:1)选择性较差,大多数PARP-1抑制剂对于PARP-2也具有一定抑制作用,PARP-2缺陷或受到抑制后,增加脑中风、胚胎畸形及贫血风险;2)半衰期均很短,需频繁给药,患者顺从性较差;3)副作用发生较高,如血液和淋巴系统紊乱和胃肠道反应,少有停药后出现肺炎和胚胎毒性等;4)给药剂量较大,是否存在隐匿毒性还需进一步考察。因此,结构新颖、作用效果更佳、毒性更小和药物动力学属性更好的新型PARP-1抑制剂仍然备受期待。

实施例46检测化合物在酶水平抑制PARP-1/2的IC50
实验方法
将化合物样品用无水二甲基亚砜溶解,配制10mM母液,然后把化合物加到筛选体系中,化合物检测浓度范围是0.5nM~10μM,按照3倍梯度进行稀释,每个浓度做两个复孔。实验结果换算成活性百分率,将药物浓度作为横坐标,各浓度对应的酶活性百分率作为纵坐标,计算得到受试化合物对PARP-1/2酶抑制的IC50值。具体操作步骤如下:在96孔板中测试目标化合物对PARP-1/2酶的抑制活性。各孔预涂稀释在100μL PBS缓冲液(10mM磷酸二氢钠,10mM磷酸氢二钠,150mM氯化钠,pH 7.4)中的组蛋白(20μg/mL),4℃下培养过夜。之后,每孔加入稀释在30μL缓冲液(50mM Tris,2mM氯化镁,pH 8.0)中的100μM的NAD+,25μM生物素化的NAD+和200nM siDNA,然后加入不同浓度的5μL受试化合物或溶剂对照。30℃下每孔加入20μL(5ng)PARP-1,1h后加入50μL HRP,培养30min后再加100μL缓冲液(0.1M H2O2柠檬酸盐缓冲液,pH 5.4)终止反应,在SpectraMax M5仪器上检测化学发光值。
实验结果:实验结果显示,化合物11-13,27,28的PARP-1抑制率IC50值小于25nM,其中优选化合物27的PARP-1抑制率IC50值为效15nM,效果略弱于上市药Olaparib(IC50=5.1nM)。但其选择性为60,远远大于上市药Olaparib(选择性0.2),临床意义更大。

动物分组:空白组,奥拉帕尼组(Olaparib,10mg/kg)、化合物27低剂量组(25mg/kg)及化合物27高剂量组(50mg/kg)。每隔两天测一次瘤直径,用游标卡尺测量瘤体短径a及长经b(包括皮肤厚度在内),计算瘤体体积V=a2×b/2,并绘制肿瘤生长曲线。在实验的最后一天,剥离肿瘤,拍照记录。
实验结果如图2所示,结果显示,在较低剂量下优选化合物27就可明显抑制荷瘤小鼠皮下SK-OV-3肿瘤细胞生长,等剂量下效果优于上市药物药奥拉帕尼。
实施例49优选化合物27的体内化疗增敏药效试验
将A549细胞复苏后,按照常规细胞培养方法扩增细胞。当细胞涨到指数期时,收集细胞,制备成5×108cells/mL的细胞悬液,肿瘤细胞混悬液的制备均在无菌条件下(超净工作台中)完成。吸取上述制备的肿瘤细胞混悬液0.3mL接种于小鼠右侧腋窝皮下,接种完毕在60min内完成。当瘤体积达到100mm3,进行分组及给药。
动物分组:空白组,卡铂组、卡铂+奥拉帕尼组(Olaparib,10mg/kg)、卡铂+化合物27低剂量组(25mg/kg)及卡铂+化合物27高剂量组(50mg/kg)。每隔两天测一次瘤直径,用游标卡尺测量瘤体短径a及长经b(包括皮肤厚度在内),计算瘤体体积V=a2×b/2,并绘制肿瘤生长曲线。在实验的最后一天,剥离肿瘤,拍照记录。
实验结果如图3所示,结果显示,在较低剂量下优选化合物27就可明显增加卡铂对肿瘤的抑制作用,等剂量下效果优于上市药物药奥拉帕尼。
