Abstract

Description
技术领域
本发明属于化合物合成技术领域,涉及一种呋喃并吡啶酮类化合物及其应用,尤其涉及一种作为溴结构域抑制剂的呋喃并吡啶酮类化合物及其应用。
背景技术
表观遗传调控主要包括DNA化学修饰(如胞嘧啶的甲基化)和组蛋白修饰(如乙酰化、甲基化、磷酸化和泛素化)。这些表观遗传调控方式共同决定了基因的激活和沉默,以此来响应生理过程和外界环境的刺激。其中,组蛋白的乙酰化,特别是赖氨酸的乙酰化被视为基因转录激活的标志,在正常生命过程和疾病中起着重要的作用。溴结构域(bromodomain,BRDs)是特异性地识别赖氨酸乙酰化位点的阅读器,通过形成转录复合物来介导信号转导和调控基因网络。
目前,在人体内的46个蛋白质中发现了61个溴结构域。其中,BET(bromodomainand extra-terminal domain)家族包括BRD2、BRD3、BRD4和BRDT。结构上,它们都有两个串联的BD溴结构域和一个外末端结构域(ET)。从BET家族蛋白N-末端开始编号,串联的BD溴结构域通常被标记为溴结构域1(BD1)和溴结构域2(BD2)。
BET家族蛋白通过招募转录调控复合物到乙酰化组蛋白,从而参与了许多以DNA为中心的生命过程,当BET家族蛋白功能发生障碍时则导致了多种人类疾病的发生。研究证实,靶向BET溴结构域的药物可用来治疗癌症、炎症、糖尿病、心血管疾病以及抗男性生育等疾病。与此同时,研究发现BET家族的BD1和BD2溴结构域可以通过识别不同的乙酰化赖氨酸,发挥不同的转录调节功能。开发选择性BET家族BD1或BD2抑制剂,有助于进一步理解该串联溴结构域各自的功能,同时可能有助于降低药物治疗过程中的毒副作用。
因此,在本领域开发具有选择性BD1或BD2抑制剂是研究的重点。

生物活性测试
化合物的体外酶学活性测试(一)
化合物对BET溴结构域的酶结合反应的抑制IC50值采用均相时间分辨荧光(HTRF)的方法进行。C端生物素化的bH4KAc4多肽序列为:H-YSGRGK(Ac)GGK(Ac)GLGK(Ac)GGAK(Ac)RHRK-Biotin-OH。Eu3+cryptate-lable anti-His antibody购买自Thermo Fisher;Streptavidin-XL-665购买自PerkinElmer;384孔板购买自PerkinElmer。反应缓冲液:20mMHEPES,150mM NaCl,5mM DTT,0.005%Tween 20和100μg/mL BSA,pH调至7.5。所用溴结构域蛋白皆带有His标签。
化合物用DMSO进行梯度稀释,每个浓度取20nL加入到384孔板中。随后加入10μL含有His标签的溴结构域蛋白(终浓度2nM)和生物素标记的多肽(终浓度20nM)的混合液,室温孵育1小时。加入10μL含有Eu3+cryptate-lable anti-His antibody和Streptavidin-XL-665的混合液,室温孵育1小时。在EnVision(PerkinElmer)上读取荧光值(320nm激发波长,检测620nm和665nm的发射光)。HTRF酶结合信号=665nm信号强度/620nm信号强度;每个化合物在10个浓度下测定与蛋白的结合强度,数据使用GraphPad Prism软件计算得到化合物的IC50值。
上述部分化合物的测试结果如表1所示
表1化合物的体外酶学活性结果
由表1可以看出,所有化合物都具有极强的BRD4溴结构域结合活性(单nM级别),并且部分化合物具有更好的BD2溴结构域选择性。具体而言,当R2为R3、R4各自独立为甲基、乙基、甲氧基;R8为 时,化合物具有更好的BD2溴结构域选择性。
化合物的体外酶学活性测试(二)
采用TSA实验(Thermal Stability Shift Assay)测定结合蛋白后稳定蛋白能力。其实验结果由ΔTm(℃)呈现,当ΔTm数值越大,说明化合物结合后稳定蛋白能力越强,蛋白结合能力越强。实验步骤:将不同组分的母液稀释到合适的加样浓度,随后加入20μL的反应体系,包括2μL蛋白、2μL SYPRO Orange荧光染料、10μL化合物、2μL缓冲液(10×缓冲液:100mM HEPES、1500mM NaCl、50%(v/v)甘油,加入去离子水配成50mL,pH 7.5)、4μL去离子水,充分混合后加入96孔板中。室温下以1000r/min离心1min,冰上孵育30min。将孵育好的96孔反应板放入实时定量PCR仪,设置程序升温范围为30℃~80℃,温度变化间隔为0.3℃,每5秒读数一次。保存文件,分析实验数据。
上述部分化合物的测试结果如图1所示,JQ1为已知的高效BET溴结构域抑制剂,纵坐标为23种溴结构域代表性蛋白,(其中BET家族包括BRD4、BRD3、BRD2、BRDT,每个成员包括BD1、BD2);图中的数值代表化合物与蛋白的结合强度,数值越大结合越强。由图1可以看出,化合物39、40、42、44具有极强的BET BD2结合活性、极高的BD2选择性,并且具有很好的溴结构域选择性,对其他溴结构域蛋白没有结合活性。
化合物的体外酶学活性测试(三)
化合物对BET家族溴结构域的酶结合反应的Kd值采用生物膜层干涉(Biolayerinterferometry,BLI)方法进行。使用生物素化试剂盒(G-MM-IGT,Genemore)对纯化的带His6标签溴域蛋白进行生物素化。简单地说,蛋白质和生物素化试剂在室温下用1:1摩尔比混合。反应混合物在室温下孵育1小时,然后使用10KMWCO透析盒(Thermo FisherScientific)进行透析,以去除未反应的生物素化试剂。BLI实验使用ForteBio的OctetR8仪器进行。所有检测方法均在30℃下运行,振荡速度为1000rpm。检测缓冲液由25mM HEPES、100mM氯化钠、0.02%Tween-20、1mg/mL BSA和1%DMSO组成,调pH至7.5。通过将传感器浸入蛋白溶液中,将生物素化的BET家族蛋白结合在超级链霉亲和素(SSA)生物传感器(ForteBio)上。所有BET家族蛋白在10分钟内达到平均饱和响应水平10-15nm。然后在检测缓冲液中洗涤传感器10分钟,以消除非特异性结合蛋白,并建立稳定的基线,然后开始与测试化合物的结合-解离循环。在整个检测过程中,DMSO空白对照同步进行。收集到的原始动力学数据在制造商提供的数据分析软件中进行处理。采用双对照扣除法,扣除DMSO对照和生物传感器不偶联蛋白的空白对照。数据结果用1:1的结合模型进行分析,从中得到Kon值和Koff值,然后计算Kd值。
上述部分化合物的测试结果如表2所示
表2化合物的体外酶学活性结果
利用BLI实验测定部分化合物的Kd结合常数,表2的结果再次验证了化合物具有极强的BD2结合活性及BD2选择性。
化合物在癌细胞上的增殖抑制活性测定
本申请中,采用Cell Titer-Glo试剂测定化合物对癌细胞的增殖抑制能力。所用MV4-11,MOLM-13,Kasumi-1,LNCaP,22Rv1、HT-29和HFL-1细胞悬于含有10%FBS的RPMI1640培养基中,于37℃在5%的CO2培养箱中培养。各种细胞在复苏后,至少传代培养两代再使用。使用时,细胞以每孔500-1000个细胞接种在384孔板中。贴壁细胞:每孔含20μL培养基,置于细胞培养箱中培养12小时后,将10μL的化合物加入每孔中每个浓度做三个复孔;悬浮细胞在接种细胞的同时不经培养12小时,直接加入测试化合物即可。对于MOLM-13,Kasumi-1和HT-29细胞,化合物与细胞孵育培养72小时后进行测试;对于LNCaP和22Rv1细胞,化合物与细胞孵育培养96小时后进行测试;对于MV-411细胞,化合物与细胞孵育培养120小时后进行测试。测试时:加入25μL CellTiter-GLO试剂(Promega),根据制造商的说明利用GLOMAX微孔板光度计(Promega)测量荧光信号。使用GraphPad Prism 6软件计算最大半数抑制浓度(IC50)值。
上述实施例编号42和1的测试结果如表3所示,其中细胞种类如下:白血病细胞:MV4-11,MOLM-13,Kasumi-1;结直肠癌细胞:HT-29;前列腺癌细胞:LNCaP,22Rv1;人正常肺纤维细胞:HFL-1。
表3
由表3可以看出,以化合物1为代表的全靶BET抑制剂,在多种癌细胞中都具有极强的抑癌活性,说明这一系列的BET抑制剂具有很好的细胞活性效果;而以化合物42为代表的BD2选择性抑制剂则抗癌效果更集中在某些癌细胞系上,例如MV4-11,同时化合物42具有更高的安全性,对人正常细胞HFL-1更为安全,从而说明这些BD2抑制剂的有效性和安全性。
