Description
技术领域
本发明属于医药化工技术领域,具体涉及以吲哚或氮杂吲哚为母核的KRAS抑制剂及其制备方法。
背景技术
恶性肿瘤是一类严重危害人类生命健康的基因变异性疾病。RAS基因是人类肿瘤中突变频率最高的基因之一。其编码的产物RAS蛋白是一种鸟嘌呤核苷酸结合蛋白,是细胞信号转导通路中至关重要的分子开关,在细胞增殖、分化和调亡等生命过程中起着重要的调节作用。RAS基因的突变致使细胞信号通路失控,与人类30%恶性肿瘤的发生、发展和预后不良密切相关。
KRAS蛋白是RAS家族中最常见的突变亚型,约占RAS家族突变总数的85%。KRAS一度被认为是不可成药的靶点,究其原因,主要有两个:(1)KRAS和内源性配体GDP/GTP的亲和力非常强,达到了皮摩尔级别,无法开发竞争性抑制剂;(2)KRAS蛋白表面光滑,没有较深的疏水口袋,无法开发变构抑制剂。因此,人们一直希望能研发出靶向KRAS蛋白的抗肿瘤药物,但是该过程进展缓慢。然而经过近三十年的努力,人们终于对KRAS突变体的抑制剂的研究取得了较大进展,例如安进公司开发的AMG510作为KRAS G12C抑制剂,于2021年获得美国FDA批准用于治疗非小细胞肺癌以及结直肠癌。因此,开发靶向KRAS的小分子抑制剂具有十分重要的意义。
发明内容
本发明提供新型的以吲哚或氮杂吲哚为母核的KRAS抑制剂及其制备方法和应用。本发明基于KRAS结构特点,设计新型的以吲哚或氮杂吲哚为母核的小分子抑制剂,该吲哚或氮杂吲哚母核取代芳香环或芳杂环为疏水结合区域,与KRAS蛋白发生π-π相互作用;另外,丙烯酰基团与KRAS蛋白的G12C突变氨基酸位点共价结合。经KRAS抑制活性评价发现本发明的新型化合物有良好的KRAS抑制活性,对带有KRAS突变的细胞,例如人非小细胞肺癌细胞H358具有良好的抑制活性,可用于制备治疗持有KRAS突变的肺癌等恶性肿瘤的药物。
本发明的化合物是KRAS的小分子抑制剂,目前针对此靶点的抑制剂较少。RAS原癌基因的突变是人类癌症中最常见的激活突变,驱动人类30% 肿瘤的发生与发展,因此人们一直希望能够研发出靶向RAS 蛋白的抗肿瘤药物,但进展缓慢。KRAS蛋白是RAS家族中最常见的突变亚型,约占Ras家族突变总数的85%。因此开发KRAS小分子抑制剂具有十分重要的意义。针对根据本发明制备的以吲哚或氮杂吲哚为母核的小分子抑制剂进行KRAS的抑制活性评价,以及对KRAS突变的人非小细胞肺癌的抑制活性和选择性研究,探索其构效关系,为开发靶向KRAS蛋白肺癌药物的开发提供理论依据。

测试例1 H358, A549, Beas-2B细胞抗增殖活性测试
实验原理:H358细胞为KRAS G12C突变肺癌细胞,A549为G12D突变肺癌细胞,Beas-2B为肺部正常上皮细胞。通过CCK-8法检测给药后对H358细胞的增殖能力的影响来检测上述实施例制备的化合物的活性,同时考察化合物对非G12C突变的A549细胞的选择性和对正常肺部细胞Beas-2B的毒性。阳性药选择为AMG510。
H358细胞抗增殖活性测试内容为:
1. 收集对数期细胞,调整细胞悬液浓度,每孔(96孔平底板)加入100 μL,铺板使待测细胞密度至5000/每孔,边缘孔用无菌PBS填充)。置于5% CO2的培养箱中,37 °C孵育。
2. 待细胞贴壁后,更换新鲜培养基并加入终浓度为20 μM的化合物(3个复孔),继续放置于恒温培养箱中。
3. 孵育72 h后,每孔加入10 μL的CCK-8试剂,轻轻混匀,并将培养板置于37 °C,5% CO2培养箱中孵育2小时。
4. 将孵育后的细胞培养板置于酶标仪上,在450 nm处检测其吸光值。
上述方法可检测化合物对A549,Beas-2B细胞的抗增殖能力(铺板密度为2000个/每孔),并计算其抑制率。抑制率= (OD空白组-OD给药组)/OD空白组*100%
