Description
技术领域
本发明属于药物化学领域,公开了一类具有CDK激酶抑制活性的氨基取代的芳香杂环并吡唑类化合物、其药物组合物和用途,具体为如通式I所示的化合物。本发明的化合物及包含这些化合物的药物组合物可用于预防或治疗相关疾病,所述疾病特别是由CDK激酶尤其CDK7激酶的异常活性介导的。
背景技术
细胞周期异常是癌症的一个标志性特征,周期蛋白依赖性激酶(cyclin-dependent kinase,CDK)是一类丝氨酸/苏氨酸激酶,在细胞周期中起中心作用,主导细胞周期的启动、进行和结束。CDK家族是细胞内重要的信号转导分子,其与周期素(cyclin)形成的CDK-cyclin复合物,参与细胞的生长、增殖、休眠和凋亡。
在过去的20年中,以CDK激酶为肿瘤治疗靶点的药物开发已经得到了广泛的关注,如Flavopiridol(Alvocidib),Seliciclib(CYC202),Dinaciclib(SCH727965)和Milciclib(PHA-848125)等都进入不同阶段临床研究。但是由于早期发现的CDK抑制剂对各CDK家族亚型抑制活性不高,或者缺乏一定的选择性,或者体内吸收不佳等情况而限制了临床应用。近几年,由于提高了CDK抑制剂对于各CDK家族亚型的选择性或者提高了CDK激酶的抑制活性,尤其是靶向CDK4/6的选择性抑制剂的发现,使得这一领域的药物研发再次成为热点。
最新研究发现CDK家族的CDK7激酶同时具有调控激酶和转录的双重功能:1)在胞质中,CDK7以异三聚体复合体的形式存在并且充当CDK1/2的激活激酶(CAK),借此CDK7对CDK1/2中的保守残基进行的磷酸化是为完全的催化CDK活性和细胞周期进展所必需的;2)在核中,CDK7形成RNA聚合酶(RNAP)II通用转录因子复合物的激酶核心并且负责将RNAPII的C末端结构域(CTD)磷酸化,这是基因转录起始中的一个必要的步骤。CDK7的两个功能,即CAK和CTD磷酸化支持了细胞增殖、细胞循环、以及转录的关键方面。研究表明,CDK7激酶对于三阴性乳腺癌的调控具有非常重要的作用,抑制CDK7激酶对于三阴性乳腺癌细胞的生长具有显著的杀伤作用。
另外,CDK家族的CDK9激酶主要在转录延伸的调控中发挥作用,而不影响细胞周期过程。CDK9抑制剂可通过降解、抑制CDK9来阻断正性转录延长因子P-TEFb(positivetranscription elongation factor b)对RNA Poly-II C末端区域的磷酸化,抑制转录,迅速降低细胞内mRNA水平,从而引起肿瘤细胞凋亡。
CDK激酶抑制剂类药物研发尽管已经取得了非常重大的进展,但是同时还存在一些未能解决的问题,如已有CDK激酶抑制剂类药物的耐药性、对CDK激酶家族靶点的亚型选择性等,因此,本领域迫切需要研究和开发新的高效低毒、抗耐药性、具有临床应用价值的新型CDK激酶抑制剂,如特异性CDK7激酶抑制剂。

检测实施例化合物在CDK7/CycH/MAT1(Carna)和CDK9/CycT1(Carna)激酶上的抑制率,以PHA-793887和Dinaciclib作为阳性对照化合物。利用Mobility shift assay的方法,在2种激酶上进行实施例化合物的活性测试。
具体操作流程如下:(1)配制1×Kinase buffer;(2)化合物浓度梯度的配制:受试化合物测试浓度为10000nM起始,在384source板中稀释成100倍终浓度的100%DMSO溶液,3倍稀释化合物,10个浓度。使用分液器Echo 550向目的板384-well-plate转移250nL 100倍终浓度的化合物。用1×Kinase buffer配制2.5倍终浓度的激酶溶液。(3)在化合物孔和阳性对照孔分别加10μL的2.5倍终浓度的激酶溶液;在阴性对照孔中加10μL的1×Kinasebuffer。(4)1000rpm离心30秒,反应板振荡混匀后室温孵育10分钟。(5)用1×Kinasebuffer配制5/3倍终浓度的ATP和Kinase substrate的混合溶液。(6)加入15μl的5/3倍终浓度的ATP和底物的混合溶液,起始反应。(7)将384孔板1000rpm离心30秒,振荡混匀后室温孵育相应的时间。(8)加入30μl终止检测液停止激酶反应,1000rpm离心30秒,振荡混匀。(9)用Caliper EZ Reader读取转化率。(10)计算公式%Inhibition=Conversion%_max-Conversion%_sample/Conversion%_max-Conversion%_min×100,其中:Conversion%_sample是样品的转化率读数;Conversion%_min是阴性对照孔均值,代表没有酶活孔的转化率读数;Conversion%_max是阳性对照孔均值,代表没有化合物抑制孔的转化率读数。拟合量效曲线以浓度的log值作为X轴,百分比抑制率为Y轴,采用分析软件GraphPad Prism 5的log(inhibitor)vs.response–Variable slope拟合量效曲线,从而得出各个化合物对酶活性的IC50值。计算公式是Y=Bottom+(Top-Bottom)/(1+10^((LogIC50-X)*Hill Slope))。
结果:本发明大部分实施例化合物具有较高的CDK7激酶抑制活性,在低至100nM浓度下仍然显示较高的抑制活性(抑制率大于60%);并且大部分实施例化合物对CDK9的抑制活性较弱,在1000nM浓度下仍然显示较低的抑制活性(抑制率小于50%)。大部分实施例化合物显示了较高的CDK7/CDK9激酶选择性。(其中抑制率表示++++≥80%;80%<+++≤60%;60%<++≤30%;+<30%;IC50表示A≤20nM;20nM<B≤100nM;100nM<C≤1000nM;D>1000nM。)
