Abstract
本发明涉及一类式(I)表示的吗啉衍生物以及包含所述吗啉衍生物的组合物。所述化合物具有优异的ATR抑制效果和作用,可以用于制备用于治疗和/或预防由ATR介导的相关疾病的药物。所述由ATR介导的相关疾病选自癌症或过度增殖性疾病
Description
技术领域
本发明涉及药物化学领域,具体涉及一类作为ATR抑制剂的吗啉衍生物及其制备方法和应用。
背景技术
共济失调毛细血管扩张突变基因Rad3相关蛋白(Ataxia TelangiectasiaMutated and Rad3Related Kinase,ATR)是与DNA损伤信号传导和修复相关的磷脂酰肌醇3-激酶相关激酶(PIKK)家族成员,由2644个氨基酸组成,N端为ATR相互作用蛋白(ATRinteracting protein,ATRIP)结合结构域,是ATR激活的重要结构域,C端为下游蛋白磷酸化的激酶结构域,具有将靶蛋白如细胞周期检测点激酶1(cell cycle checkpoint kinase1,Chk1)等丝氨酸或苏氨酸磷酸化的功能。ATR在DNA修复中起着重要作用,负责启动细胞对基因组不稳定的响应和修复,一旦感应到DNA损伤和复制叉压力会迅速活化,直接磷酸化下游效应蛋白启动调控基因组的稳定(Nat Rev Mol Cell Biol.2008Aug;9(8):616-27)。
DNA损伤或复制压力诱导单链DNA(single-stranded DNA,ssDNA)募集复制相关蛋白A(replication protein A,RPA)形成RPA-ssDNA复合物,RPA-ssDNA可以招募ATR激活所需的调控因子,包括ATRIP复合物、RAD9-RAD1-HUS1(9-1-1)复合物、RPA复合物、拓扑异构酶Ⅱβ结合蛋白1(TopoisomeraseⅡBinding Protein 1,TopBP1)等。首先ATR通过与其配体ATRIP结合被招募到RPA-ssDNA上形成ATR-ATRIP复合物,同时ATR发生自磷酸化;随后在RPA-ssDNA调控下dsDNA-ssDNA接合处募集TopBP1等复合物,被募集到dsDNA-ssDNA接合处的TopBP1通过与ATR自磷酸化位点结合使ATR-ATRIP激活;ATR一旦被激活将磷酸化Chk1及其他效应蛋白,活化的Chk1继续磷酸化其下游效应物质(如CDC25A),最终促使细胞周期停滞,稳定复制叉并促进DNA损伤修复(J Hematol Oncol.2019Apr 24;12(1):43)。
基因组的不稳定性是肿瘤细胞的基本特征之一。许多肿瘤细胞都存在DNA的异常损伤,导致其更依赖于未受损的DNA修复通路,因此ATR被视为肿瘤的潜在治疗靶点。大量功能和临床前实验数据表明,ATR激酶抑制剂能高效杀死肿瘤细胞。此外,化疗和放疗会进一步加剧肿瘤细胞的基因组不稳定性,抑制ATR活性能协同增强抗肿瘤效果。因此,ATR激酶抑制剂在肿瘤治疗上具有重要应用前景(J Neurosci.2017Jan 25;37(4):893-905)。
ATR作为DNA损伤修复的关键蛋白,对细胞的存活起重要作用。对ATR的抑制可以诱导ATR通路依赖型恶性肿瘤细胞凋亡而对正常细胞生长和增殖影响较小,因此ATR可作为低毒且高效靶向抗肿瘤药物的理想靶点。
目前的ATR抑制剂已有VX-970、AZD6738、BAY1895344和VX-803进入临床试验,也有多篇针对ATR通路的专利公开,如:WO2019/014618、WO2019/050889、WO2019/154365、CN111205310A、CN11046761A、WO2015/084384、WO2017/180723、WO2016/061097等等,但尚未有相应的药物上市。基于ATR抑制剂在癌症等所展示的前景,仍需开发新的化合物。

在本发明中,“治疗”一般是指获得需要的药理和/或生理效应。该效应根据完全或部分地预防疾病或其症状,可以是预防性的;和/或根据部分或完全稳定或治愈疾病和/或由于疾病产生的副作用,可以是治疗性的。本文使用的“治疗”涵盖了对患者疾病的任何治疗,包括:(a)预防易感染疾病或症状但还没诊断出患病的患者所发生的疾病或症状;(b)抑制疾病的症状,即阻止其发展;或(c)缓解疾病的症状,即,导致疾病或症状退化。

体外酶学活性评价
通过测定IC50值来评价化合物对人的ATR激酶的抑制活性。
主要试剂及耗材:
实验方案:将终浓度为0.25ng/μL的重组人ATR/ATRIP在含有终浓度为20nM GST-cMyc-p53和4μM ATP的测定缓冲液中培育,反应通过添加ATP来引发。在室温下培育30分钟后,加入EDTA终止溶液终止反应。最后,加入含有d2标记的抗GST的单克隆抗体和铕标记的抗磷酸化p53(ser15)的抗体,在恒温培养箱(25℃)过夜培育,然后通过Envision用时间分辨荧光模式读取反应体系在665nm和615nm下的荧光信号,以均相时间分辨荧光法并根据公式HTRF=(Em665nm/Em615nm)确定荧光(HTRF)信号。
使用数据分析软件GraphPad Prism 8,采用方程“log(inhibitor)vs.normalizedresponse--variable slope”(公式Y=100/(1+10^((LogIC50-X)*HillSlope)进行数据分析,得到化合物的IC50值。公式中,“X”表示化合物的摩尔浓度;“Y”表示对酶活性的百分比抑制率;“HillSlope”是指曲线最大斜率的绝对值。
