本发明涉及医药技术领域,具体地说,是一种喹诺里西啶类组蛋白去乙酰化酶抑制剂及其制备方法与应用。
背景技术
组蛋白去乙酰化酶(HDACs)是一类锌离子依赖性的金属蛋白酶,可以催化水解组蛋白中赖氨酸残基侧链末端ε-氨基上的乙酰基,使组蛋白的正电荷密度增加,与带负电荷的DNA之间的静电吸引力增强,从而使染色质呈紧密卷曲的阻抑结构,导致转录因子和RNA聚合酶无法与DNA结合,最终使基因转录受到抑制。另外,HDACs还参与调节多种非组蛋白的乙酰化作用,包括α-微管蛋白(α-tubulin),皮层肌动蛋白(cortactin),热休克蛋白90(HSP-90)和过氧化物还原酶I/II(peroxiredoxins I/II)等。HDACs底物的多样性决定了其功能的复杂性,因此HDACs功能的失调会引起许多疾病,而癌症就是其中之一。HDACs与癌症的发生发展密切相关,在肿瘤细胞中,常常存在着HDACs的异常过度表达,使得抑癌基因不能正常转录,促进了肿瘤细胞的发生和发展。HDACs对肿瘤的增殖、血管生成、转移、分化、自噬及凋亡等过程中均有重要作用。另外,研究表明组蛋白H4的过度去乙酰化是癌症发生早期的一个显著性标志。近年来,HDACs已经成为抗肿瘤研究的一个热点,抑制HDAC的活性是肿瘤治疗的一种确证策略。截至目前,共有5个HDACs抑制剂伏立诺他(SAHA)、罗米地辛(FK228)、贝利司他(PXD101)、帕比司他(LBH589)和西达苯胺(CS055)被批准上市用于多种血液瘤的治疗。
尽管取得了这些进展,但设计更新颖、更有效的HDAC抑制剂仍然是非常必要的。因此,本发明找到了更高活性的HDAC抑制剂,目前还未见报道。
天然产物一直都是新药发现和发展的重要源泉。槐定碱(sophoridine)是从豆科槐属植物苦豆子中提取的喹诺里西啶生物碱单体,具有广泛的药理学作用,例如抗肿瘤、抗病毒、抗炎等。2005年盐酸槐定碱注射液被批准上市,用于治疗滋养细胞瘤。槐定碱与现有抗癌化疗药结构不同,是一类新型的抗癌新药,但其活性有限且抗瘤谱窄。通过对槐定碱进行结构修饰,获得结构新颖且安全有效的抗肿瘤药物,在本领域仍有巨大需求。槐定碱结构如下:。
本发明的发明人以槐定碱为先导化合物,通过对槐定碱的结构进行改造和修饰,得到了一种喹诺里西啶类组蛋白去乙酰化酶抑制剂,本发明即是基于以上发现而完成。

实施例5:
本发明部分化合物对HDAC1酶的抑制活性
实验材料:
HDAC1酶,缓冲液(137mM氯化钠,2.7mM氯化钾,1mM氯化镁,0.1mg/mL BSA,pH=8的Tris-HCl 25mM),HDAC substrate 3,胰蛋白酶,96孔黑色板。
2. 实验方法:
(1)96孔板平衡至室温;
(2)用含有10% DMSO的缓冲液稀释待测化合物,化合物浓度依次为100 μM,30 μM,10 μM,3 μM,1 μM,0.3 μM,0.1 μM,0.03 μM,0.01 μM,0.003 μM;
(3)将11 μL的HDAC1加入到400μL的缓冲液中,摇匀;
(4)向96孔板上的第2-11孔加入35 μL配好的含有HDAC1酶的缓冲液,并依次加入5μL稀释好的不同浓度的化合物到对应的反应孔中,对于阴性对照(第1个孔)和空白对照孔(第11个孔),分别加入40 μL和5 μL的assay buffer;
(5)向所有反应孔中加入100 μM的HDAC substrate 5 μL和0.5 mg/mL的胰蛋白酶5 μL,37°C孵化30分钟后读数。
(6)依据公式计算抑制率:抑制率=(100%活性孔-样品孔)/100%活性孔*100,在GraphPad软件中将酶活性对化合物浓度的曲线进行拟合,求出化合物的IC50值;
实验结果(表2)表明,这些化合物都表现出良好的HDAC1抑制活性,其中化合物7f(IC50 = 32 nM)、7g(IC50 = 27 nM)、7p(IC50 = 41 nM)、11a(IC50 = 16 nM)、11b(IC50 = 23nM)、11d(IC50 = 39 nM)、11e(IC50 = 30 nM)、11f(IC50 = 34 nM)、14(IC50 = 7 nM)和9(IC50 = 13 nM)表现出优于阳性对照药SAHA(IC50 = 44 nM)的HDAC1抑制活性。
实施例6:
本发明部分化合物的体外抗肿瘤活性测试(MTT法)
1. 实验材料
MTT,PRMI1640培养基,胎牛血清,96孔板,CO2恒温培养箱,BIO-TEK Uquant多功能酶标仪,人乳腺癌细胞(MDA-MB-231)、人肺癌细胞(A549)和人正常肝细胞(L02),阳性对照药SAHA。
2. 实验方法
(1)接种细胞,用含10%胎牛血清的培养液配成单个细胞悬液,以每孔5000个细胞接种到96孔板,每孔体积100 μL,培养过夜。
(2)待测化合物溶液的配制,在无菌台中,将化合物的DMSO储备液以培养液稀释成待测5个浓度,相邻浓度之间为两倍稀释。
(3)将不同浓度的化合物溶液加入已经培养过夜的96孔板中,每孔加入100 μL,每个浓度加3个复孔。周围由于具有边缘效应,易染菌,因此不加细胞,不加化合物,而加100 μL的培养液用作空白。另设置100%孔,即加入细胞和不含化合物的培养液100 μL,在37°C恒温培养箱中孵育48小时。
(4)染色,向96孔板中加入10 μL MTT溶液(5 mg/mL,用PBS配制)染色,孵育4小时后,2500 rps离心10分钟,然后用排枪将培养液从孔中吸出,,加入150 μL DMSO,在震荡板震荡5-10分钟,使甲瓒充分溶解,用酶标仪测定570 nm每孔的OD值。
抑制率(%)=(100%孔平均OD值-化合物孔平均OD值)/(100%孔平均OD值-空白孔平均OD值)×100%。根据各个浓度的抑制率值,进行线性回归,算出抑制细胞生长50%的药物浓度,即IC50。
实验结果(表3)显示,所测试目标化合物均具有显著的抗肿瘤细胞增殖活性,除了化合物11g外,所测试化合物活性均强于阳性药SAHA,其IC50值在0.12-2.99 μM之间,且对正常细胞L02细胞毒性较低,对肿瘤细胞具有选择性。
实施例6:目标化合物体内抗肿瘤效果
根据以上实验结果,选择人乳腺癌细胞株MDA-MB-231裸鼠移植瘤模型对化合物11e和19的体内抗肿瘤活性进行了测试,给药剂量为30 mg/kg,腹腔注射每天给药两次,连续给药14天。结果显示(表4),化合物11e和19均表现出优秀的体内抑制活性,体内抑瘤率分别为78.0%和84.6%,显著优于相同剂量下的阳性药SAHA对照组(42.8%)。此外,在给药期间,并未发现小鼠体重明显变化,说明化合物11e和19的体内毒性较低。
这表明,化合物11e和19能够显著抑制人乳腺癌细胞株MDA-MB-231裸鼠移植瘤生长,均明显优于阳性药SAHA,且毒性较低,有进一步的研究价值。
