Description
技术领域
本发明属于药物化学领域,具体涉及一种噻吩并嘧啶类化合物、其药物组合物及应用。
背景技术
大鼠肉瘤蛋白(RAS蛋白)是人体内重要的信号传导调节因子,调控包括细胞增殖、分化、迁移和生存等重要生理过程。RAS属于三磷酸鸟苷水解酶(GTPase),通过RAS与三磷酸鸟苷(GTP)结合的活性状态和RAS与二磷酸鸟苷(GDP)结合的失活状体的循环调控下游RAF/MEK/ERK和PI3K/AKT等多条重要的信号通路。这一循环包括两个过程,其中负向调节通过GTPase激活蛋白(GAP)催化RAS-GTP水解为RAS-GDP,正向调节的鸟苷酸交换因子(GEF)催化RAS与GDP解离,随后RAS会与细胞内高浓度的GTP结合。SOS1(Son of Sevenless 1)是人体内表达最广泛,功能最重要的GEF之一。
RAS蛋白家族包括KRAS(kirsten rat sarcoma viral oncogene),NRAS(neuroblastoma RAS viral oncogene)和HRAS(Harvey murine sarcoma viraloncogene),其中KRAS突变导致的肿瘤最为常见。KRAS突变导致蛋白一直处于RAS-GTP的状态,持续激活下游信号通路,在这一致癌生理过程中SOS1扮演这重要的角色。敲除SOS1能有效降低KRAS突变肿瘤的生长速度,并且不影响KRAS野生型细胞系的生长。
小分子抑制剂结合在SOS1的催化口袋,影响SOS1与KRAS蛋白的结合,可以有效的抑制RAS信号通路下游如ERK(extracellular regulated protein kinases)磷酸化水平,从而抑制肿瘤的生长。目前,勃林格殷格翰公司开发的小分子SOS1抑制剂BI-1701963(WO2018115380,WO2019122129)正处于I期临床研究阶段,并且与Mirati公司的KRAS G12C抑制剂MRTX-849合作开发联合用药的方案。此外,拜耳公司(WO2018172250,WO2019201848)和Revolution公司(WO2020180770,WO2020180768)也在这一领域发表了多篇专利,但是本领域仍然迫切需要研发出能够抑制SOS1与KRAS突变蛋白相互作用的有效药物。
值得一提的是,WO2020180770报道了一类下式所示的噻吩并嘧啶结构的SOS1抑制剂。

化合物储备液浓度为1000μmol/L起始,5倍稀释,设置8个梯度浓度,用1倍浓度缓冲液将待测化合物各梯度稀释成2%的DMSO工作液,5μL/孔加到对应孔中,每个浓度设置复孔检测。用1倍浓度缓冲液配制KRAS(G12C)突变蛋白(200nM)和Mab Anti GST-Eu cryptate(1μg/uL)的混和工作液。将该混合工作液放置25℃中孵育5分钟,2.5μL/孔加入到对应孔。用1倍浓度缓冲液配制SOS1蛋白(80nM)和Mab Anti 6HIS-XL665(8μg/uL)的混和工作液,2.5μL/孔加入到对应孔。空白孔中加入2.5μL Mab Anti 6HIS-XL665(8μg/μL)稀释液。反应体系置于25℃反应60分钟。反应结束后采用多标记分析仪读取HTRF。
4、数据处理:
用Graphpad软件计算化合物的IC50。结果如表1所示,其中A代表IC50<1μM,B代表1μM<IC50<5μM,C代表IC50>5μM。
