Description
技术领域
本发明属于药物化学领域,具体涉及CDDO-Me衍生物的,还涉及包含该衍生物的药物组合物,还涉及该衍生物用于治疗疾病的用途。
背景技术
CDDO-Me(Bardoxolone methyl)是由Reata制药和AbbVie联合开发的口服抗氧化和炎症调节剂。其通过有效激活Keap1-Nrf2通路和抑制NF-κB炎症途径发挥作用。由于具有抗氧化应激和抗炎双重作用机制,CDDO-Me在与氧化应激和炎症相关肾脏疾病中具有很好的应用前景。已完成的临床试验结果显示,虽然CDDO-Me可有效增加估计肾小球滤过率,改善慢性肾脏疾病患者肾功能,但其引起的心脏毒性也较大,因此,开发活性高、毒性低的CDDO-Me衍生物至关重要。

本发明的有益效果:
本发明的发明人发现CDDO-Me中的α-氰基-α,β-不饱和酮(a-cyano-substitutedα,β-unsaturated ketone,CUK)部分具有高活性,可以通过迈克尔加成反应与许多生物大分子中的硫醇官能团共价结合,这可能是引起CDDO-Me副作用的关键因素。发明人对CDDO-Me中的CUK片段进行结构改造,令人惊讶地发现将依赖组织蛋白酶B裂解的连接子缬氨酸-丙氨酸-对氨基苄醇(Val-Ala-PAB,VA-PAB)片段与CUK片段连接,所获得的CDDO-Me衍生物与CDDO-Me相比,实现了毒副作用的降低且表现出与CDDO-Me相当的抗氧化应激和抗炎活性。
本发明提供的CDDO-Me衍生物结构新颖,制备方法反应条件温和,所用试剂低毒,原料易得,后处理方便,产率较高。
本发明提供的CDDO-Me衍生物可显著抑制促炎介质一氧化氮的释放并激活Nrf2-ARE信号通路以及抑制NF-κB信号通路。且在hERG毒性实验中,CDDO-Me衍生物比CDDO-Me显示出较弱的抑制作用,表现出较弱的副作用。
附图说明

实验例4CDDO-Me衍生物的hERG毒性实验
本实施例评估了化合物III-4和CDDO-Me的hERG毒性。
试验过程如下所述:
1)电生理溶液的配制
a)细胞外液(mM):
将N-2-hydroxyethylpiperazine-N’-2-ethanesulfonic acid(HEPES,10g)、NaCl(145g)、KCl(4g)、CaCl2(2g)、MgCl(1g)和Glucose(10g)混合,用5M NaOH调pH至7.3~7.4;用蔗糖或纯水(或无需添加)调节渗透压至290-310msom;最后用0.22μM的滤膜过滤后置2~8℃保存,有效期为15天。
b)电极内液(mM):
将KCl(120g)、KOH(31.25g)、CaCl2(5.37g)、MgCl2(1.75g)、Ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N-tetraacetic acid(EGTA,10g)、HEPES(10g)、ATP-Na2(4g)混合,用2M KOH调节pH至7.2~7.3;用蔗糖或纯水(或无需添加)调节渗透压至290-310msom;最后用0.22μM的滤膜过滤后分装,置-20℃保存,有效期为3个月。
2)化合物的配制
分别称取一定量的化合物III-4和CDDO-Me,将其溶于DMSO中,配制成10mM的储备溶液,实验前用DMSO将上述储液按照3倍逐级稀释,然后进一步用细胞外液稀释至30、10、3、1和0.3μM,细胞外液中的DMSO最终浓度为0.5%。采取从低浓度至高浓度连续灌流的操作方式开展实验。
3)细胞悬液制备
a)将HEK-293-hERG细胞(由军事医学研究院提供)传代培养至合适状态后,从培养瓶收集后置2-8℃保存备用;
b)膜片钳记录之前,将细胞加于培养皿中,并确保细胞处于一定密度且细胞呈单个分离状态。
4)电生理实验
a)采用全细胞膜片钳技术对hERG电流进行记录。将细胞悬液滴加于小的培养皿中,并置于显微镜载物台。待细胞贴壁生长后,用细胞外液进行灌流。充灌电极内液之后其入水的电阻值为2-5MΩ;
b)待建立起全细胞记录模式之后,将钳制电位保持在-80mV。之后给予去极化电压至+60mV,并使之持续850ms,然后再将其复极化至-50mV,并维持1275ms,最后引出hERG尾电流(见图4)。此脉冲程序每15s重复进行一次,贯穿整个实验过程。
c)实验中电流稳定之后,以低浓度至高浓度细胞外连续灌流给药的方式进行实验。实验从低浓度开始,将低浓度药物持续灌流直至药效趋于稳定,然后再进行另一浓度的药物灌流。此实验将分别测试化合物III-4和CDDO-Me对hERG尾电流的阻断效应(n=3)。
5)数据的采集与分析
a)使用PatchMaster软件来进行刺激的发放以及信号的采集;信号的放大采用膜片钳放大器进行放大,滤波为10KHz;
b)通过FitMaster软件对数据进行进一步的分析,所得数据均以均值±标准差表示。不同浓度下化合物III-4和CDDO-Me的抑制作用采用尾电流的抑制率进行表示。抑制率计算公式如下:
抑制率%=100×(给待测物前尾电流的峰值-给待测物后尾电流的峰值)/给待测物前尾电流的峰值;
将所有细胞各个待测物浓度抑制率的SD≤15作为可以接受的标准(异常数据除外)。
实验结果如图5所示。化合物III-4最终浓度为0.3、1、3、10和30μM,细胞外液中DMSO最终浓度为0.5%。在本实验条件下,化合物III-4在3、10和30μM时对hERG钾通道电流有明显抑制作用,且具有浓度依赖性。由Hill方程拟合得出化合物III-4对hERG电流抑制作用的IC50值为20.94μM,Hill系数为1.06(n=3)。CDDO-Me最终浓度为0.3、1、3、10和30μM,细胞外液中DMSO最终浓度为0.5%。在本实验条件下,CDDO-Me在10和30μM时对hERG钾通道电流有抑制作用,且具有浓度依赖性。由Hill方程拟合得出CDDO-Me对hERG电流抑制作用的IC50值为13.60μM,Hill系数为1.61(n=3)。
由上述实验结果可知,化合物III-4和CDDO-Me均具有较低的hERG抑制活性,但化合物III-4的IC50值(20.94μM)明显高于CDDO-Me的IC50值(13.60μM),表明III-4显示出比CDDO-Me更少的hERG抑制作用,具有更好的安全性。
实验例5化合物III-4和CDDO-Me体外细胞毒性研究
本实施例评估了实施例3制备的化合物III-4的体外细胞毒性。具体地,评估了化合物III-4和CDDO-Me的体外细胞毒性。测试的细胞系为BT474-HDR,购自ATCC。

2)展开细胞
a)细胞在含有10%FBS(热灭活)和1%青霉素/链霉素溶液(Penicillin-Streptomycin)的培养基中以1∶4的比例每周传代三次;b)对于传代细胞,首先用0.05%的胰蛋白酶/EDTA溶液(3mL)冲洗贴壁细胞,然后加入胰蛋白酶/EDTA(3mL)并涡旋以均匀涂覆细胞。培养物在37℃下培养直到细胞分离(在显微镜下验证细胞已分离)。加入等体积的细胞培养基灭活胰蛋白酶,收集分离的细胞,并采用200×g离心细胞5分钟,之后重新悬于新鲜培养基中。
3)准备受试药
a)以1∶3比例串联稀释受试药以产生9点稀释(受试药母液为浓度约为5mM的DMSO溶液),采用含有10%FBS(热灭活)和1%青霉素/链霉素溶液(Penicillin-Streptomycin)的DMEM培养基进行稀释,细胞系BT474-HDR测试点初始最大终浓度约为5μM);b)空白对照组(well without compounds treatment)加入等体积含有10%FBS(热灭活)和1%青霉素/链霉素溶液(Penicillin-Streptomycin)的DMEM培养基。
4)细胞播种
a)收获细胞并计数细胞数量;b)将100μL细胞密度为约80000个/毫升的细胞悬液加入到96孔板中,盖上盖子,置于37℃,5%CO2培养箱中孵育过夜;c)去除96孔板中的细胞培养基,向其中加入3)步骤中准备的受试药,空白对照组加入等体积的细胞培养基,盖上盖子,置于37℃,5%CO2培养箱中孵育72小时。

6)实验结果
测试结果如图6所示。结果显示,化合物III-4和CDDO-Me在BT474-HDR细胞株上均具有细胞增殖抑制活性。化合物III-4的增殖抑制活性(IC50=0.29μM)弱于CDDO-Me(IC50=0.08μM),表明化合物III-4的细胞毒性降低,具有更好的安全性。
上述实验结果表明,本发明提供的CDDO-Me衍生物(例如化合物III-4)与CDDO-Me相比,实现了毒副作用的降低且表现出与CDDO-Me相当的抗氧化应激和抗炎活性。
