Description

吲哚胺2,3-双加氧酶抑制剂及其在制备抗肿瘤药物中的应用
技术领域
本发明属于生物医药技术领域具体涉及一类烟酸衍生物对吲哚胺2,3-双加氧酶IDO1的抑制剂其在制备免疫抗肿瘤药物中的应用
背景技术
肿瘤是一类严重危害人类生命健康的重大疾病之一,表现为细胞过度增殖和分化异常。据WHO统计,全球范围内每年癌症病例可能增加到2400万。与此同时,癌症给全球经济造成了巨大的负担。肿瘤免疫治疗是继手术、放疗、化疗后的新兴肿瘤治疗方式。它是一种利用刺激或增强人体自身免疫***的力量来预防、控制和消灭癌症的癌症治疗方法。与传统的肿瘤治疗方法相比,免疫治疗具有自身特有的优势,可以提高传统治疗的疗效,减轻传统治疗带来的不良反应等。先天免疫***激动剂、免疫检测点阻断剂和细胞免疫治疗是目前免疫治疗的主要研究领域。基于代谢调控的肿瘤免疫治疗策略,可以提高免疫治疗的有效性,让更多的患者受益,肿瘤代谢的调控为改善肿瘤免疫治疗开辟了新方向。
人体的免疫***负责识别自身与非自身,从而保护人体免受外源性和内源性疾病的侵害。人体免疫***由白细胞和淋巴器官以及淋巴组织构成,包括胸腺、脾脏、扁桃体、***、***和骨髓,免疫***通过识别并消除多种威胁来保持机体的持续稳态。癌症免疫疗法是指通过引入疫苗、细胞因子、抗体或转移的免疫细胞本身来刺激针对癌细胞的免疫***。免疫疗法在肿瘤治疗上的成功,例如免疫检查点抑制剂和CAR-T细胞疗法,已经确立了它在癌症治疗中的作用。癌症是使用多种机制来选择宿主-肿瘤免疫相互作用,从而导致免疫逃逸。在过去的几年中,我们对宿主-肿瘤相互作用的研究不断有新的进展,产生了各种有前景的免疫治疗方法。
吲哚胺2,3-双加氧酶(IDO1)是一种单体血红素蛋白,分子量为45KD。IDO1能对具有吲哚环的分子进行催化,因此被称为吲哚胺2,3-双加氧酶。IDO 1是色氨酸代谢途径中的关键限速代谢酶。大量研究表明IDO1在多种类型的人类癌症中高度表达,随后导致色氨酸代谢产物的积累,造成机体对肿瘤抗原的免疫耐受,最终导致肿瘤的免疫逃逸。许多临床前和临床试验研究表明IDO1抑制剂是对抗多种癌症的有效工具。目前,IDO1抑制剂***的临床研究正在进行,它们可以有效激活肿瘤浸润性T细胞和/或减少肿瘤驻留性免疫抑制性调节性T细胞,从而提高人体免疫,达到抗肿瘤的目的。基于IDO1在肿瘤免疫治疗中的重要作用且目前没有上市用于肿瘤治疗的IDO1抑制剂,因此,在新的IDO1抑制剂的筛选、及其基于IDO1酶抑制剂的抗肿瘤药物研究具有重要的意义。
环二核苷酸合成酶(cGAS)是先天性免疫通路中重要的细胞质DNA感受器。cGAS催化体内ATP和GTP合成cGAMP,cGAMP作为二级信使分子通过内质网膜上的STING蛋白通路诱导干扰素IFN-β和其他细胞因子的产生,调节下游蛋白质表达,诱导细胞生长停滞和凋亡,产生抗病毒效应。STING通路可以调节免疫原性肿瘤的先天免疫识别,促进干扰素的抗肿瘤作用。IFN-γ在体内通过TRAIL(tumor necrosis factor-related apoptosis-inducingligand)发挥抗肿瘤作用,促进肿瘤细胞凋亡。cGAMP是先天免疫反应的关键刺激物,是STING的内源性激活剂,具有免疫抗肿瘤作用。
本研究发明了一类创新的吲哚胺2,3-双加氧酶IDO1的抑制剂,即烟酸衍生物(3-吡啶丙酸的衍生物)。该类3-吡啶丙酸的衍生物能有效抑制吲哚胺2,3-双加氧酶IDO1催化色氨酸代谢,在人源癌细胞中能显著抑制高表达的IDO1酶活性,而且细胞毒性较低。这些烟酸类似物作为IDO1酶的抑制剂单独使用能显著抑制小鼠移植肿瘤生长,其与先天免疫通路STING激动剂联合使用/或与免疫检查点抑制剂联和使用/或与抗肿瘤化药联合使用,抑制肿瘤生长药效更佳,安全性也很好。因此,这类烟酸衍生物在制备免疫抗肿瘤药物中具有广阔的应用前景。

具体实施方式
下面通过实施例具体说明本发明的内容。在本发明中,以下所述的实施例是为了更好地阐述本发明,并不是用来限制本发明的范围。
实施例1:烟酸衍生物对IDO1金属酶的抑制作用研究
所有生物化学试剂均为分析纯,购于Sigma-Aldrach。烟酸衍生物1-10的结构式及其英文名称见附图1.
1、吲哚胺2,3-双加氧酶1(IDO1)按照文献方法制备
选择pGEX-6P-1作为构建人源IDO1表达质粒的载体,带有GST融合标签的IDO1蛋白在大肠杆菌中可容表达,IDO1融合蛋白使用GST亲和柱进行吸附纯化且蛋白纯度极高,采用重组HRV 3C蛋白酶进行酶切GST标签蛋白,在16℃的条件下酶过夜,酶切后的IDO1蛋白经二次使用Glutathione Sepharose亲和柱纯化,得到电泳纯蛋白,经SDS-Page和质谱鉴定。SDS-PAGE显示IDO1蛋白纯度高于95%,MALDI-TOF质谱进一步确认了IDO1的分子量为45KD,这与理论分子量相吻合;紫外可见光谱表征显示特征吸收峰为404nm,电化学还原电位为-0.37V。实验结果证明,我们成功的获得了高纯度的人源IDO1蛋白,为后续IDO1抑制剂筛选及酶活性相关实验的顺利进行奠定了基础。
2、烟酸衍生物抑制IDO1酶活性的IC50值测定
实验方法:
用KH2PO4(100mM,pH 6.5)缓冲溶液,根据IDO1的摩尔消光系数计算1μM蛋白在404nm紫外吸收值来准备蛋白样品。准备1.5mL的EP管,做好化合物各浓度梯度的标记;然后取1mL、1μM蛋白于EP管中,作为反应体系的体积;随后分别向其中加入亚甲基蓝、过氧化氢酶、L-抗坏血酸(用NaOH调pH至6.5),试剂终浓度分别为10μM、200μg/mL和10mM;再向每个管中加入对应浓度梯度的化合物并设置不加化合物空白孔,上下颠倒混合均匀后在37℃水浴锅中孵育10min;随后在动力学测试前加入100μM底物L-色氨酸,然后立即监测320nm处反应产物N'-甲酰犬尿氨酸的吸收值,反应时间为60s。实验选择100μM色氨酸浓度下的抑制率计算抑制剂的IC50值。
数据处理:
数据处理上,首先对各个反应的动力学实验数据进行线性拟合,求出初始速率V;然后根据公式计算出不同化合物浓度下对应的抑制率,以抑制率对烟酸衍生物抑制剂浓度的Log10值进行作图,根据IC50公式进行数据拟合,即可得到各化合物的IC50值。
实验结果:IC50值测定表明10个烟酸衍生物对IDO1均有抑制作用。化合物6、7、8、9、10上,它们的IC50值均在10μM左右。8个化合物均表现出比阳性对照化合物4-PI(IC50:49.03±6.67μM)更高的IDO1抑制效果,其中化合物9和10的效果最好,它们在最大浓度200μM的抑制率最高,而化合物9的抑制率可以达到90%。
表1.烟酸衍生物抑制IDO1金属酶的IC50和Ki
3、烟酸衍生物抑制IDO1抑制常数Ki测定
实验方法与数据处理:
对同一种烟酸衍生物抑制剂分别在50μM、100μM和150μM三个底物浓度下进行平行的抑制活性动力学实验。首先对各个反应的动力学实验数据进行线性拟合,求出初始速率V,然后采用Cornish-Bowden作图法,在同一个数轴中以抑制剂浓度为横坐标,底物浓度与初始速率V的比值(S/V)为纵坐标,最后对三组数据进行线性拟合,拟合直线交点的绝对值即为抑制常数Ki,而通过交点Ki所处坐标轴的位置来判定抑制剂的抑制类型。导出的实验数据用Origin 7.5进行作图分析。
实验结果:
Ki值测定选择在100μM的浓度下抑制率在60%以上的化合物进行,分别是化合物2,4,5,8,9,10。实验分别用不同抑制剂浓度在50μM、100μM、150μM三种烟酸衍生物底物浓度下进行平行实验,以S/V对烟酸衍生物抑制剂浓度作图,三组数据线性拟合的直线交点的绝对值即为抑制常数Ki。
如表1所示,三种强IDO1烟酸衍生物抑制剂8(15.56μM),9(8.68μM)和10(9.93μM)的Ki值在15μM范围内。Ki值越低,则抑制效果越强,因此,烟酸衍生物抑制剂9对IDO1具有最强的抑制效果。以上的结果表明,两种含氟化合物9和10作为以3-吡啶丙酸为母核的化合物对IDO1抑制活性最强。两者的最低IC50和Ki约为10μM。抑制剂9的抑制效果效果最为显著主要由两方面原因促成,一方面,与其他抑制剂相比,只有9具有氧和三个氟原子,F的引入可以增强IDO1和抑制剂之间的氢键结合力。特别是,9含有三氟乙基,它可以显著提高抑制剂的结合能力。另一方面,9中的羧酸被氟取代,这增加了抑制剂的疏水性,并且有利于9占据IDO1的疏水腔。总之,含有容易形成氢键的元素,特别是含有三氟乙基的化合物,它们更具有抑制IDO1的潜在优势。

3、实验内容及实验方法
本实验采用IFNγ诱导癌细胞产生IDO1,从而进行活细胞水平上的IDO1抑制剂的活性检测。
实验第一天:将用100mm培养至一定细胞密度的HeLa、HepG-2和MCF-7癌细胞用胰蛋白酶消化,显微镜下观察,细胞形态变圆后用完全培养基中止消化,将细胞用移液器轻轻吹落,离心去除胰酶。以5×104个/mL的细胞数目接种到96孔板中并设置空白对照。将其放在37℃、5%CO2的二氧化碳培养箱中培养12小时。
实验第二天:将96孔板中的细胞换液并加入200μL培养基,随后在每个培养空分别加入终浓度位10ng/mL的IFNγ、100μM的色氨酸和不同浓度梯度的抑制剂,共同培养48h。抑制剂的终浓度分别为0μM、0.5μM、1μM、5μM、10μM、20μM、40μM、60μM、80μM、100μM、150μM、200μM。阳性对照药4-PI的终浓度分别为0μM、10μM、20μM、40μM、6μM、100μM、150μM、200μM。每个样品浓度复孔3个。
实验第四天:细胞加药培养48h后,每个培养孔取140μL上清至1.5mL离心管中,加入10μL 30%(w/v)的三氯乙酸溶液,在65℃水浴条件下孵育15min终止IDO1对色氨酸的催化反应,并使N′-甲酰犬尿氨酸转化为犬尿氨酸;随后10000rpm离心10min,再取100μL的上清溶液至新的96孔板中,加入相同体积的2%(w/v)对-二甲氨基苯甲醛的乙酸溶液混合,进行显示反应;最后采用酶标仪检测492nm处的吸收值,根据产物的量来计算IDO1酶的反应速率。数据导出为excel格式,然后用GraphPad 7.00作图。细胞实验进行两次技术重复。IDO1活细胞上的抑制率计算公式:Inhibition%=[1-(A/B)]×100%(1)(A表示含有抑制剂时的吸收值,B表示不含抑制剂时的吸收值。)
4、实验结果
为了评估烟酸衍生物对活细胞中IDO1酶的抑制活性,我们对实施例1酶抑制实验筛选的抑制率大于60%的六种抑制剂进行细胞实验分析,选用三种人源癌细胞系。首先测定了20μM相同抑制剂浓度下药物对三种癌细胞中IDO1的抑制率,实验结果如表2,在Hela细胞系中,9和10对IDO1的抑制率最高,分别为14.70%和20.06%,在HepG-2细胞系中,9和10同样产生了最好的抑制效果,抑制率分别为45.61%和29.52%,而在抑制剂在MCF-7细胞系中产生的抑制作用较弱,抑制剂9略微显著,为13.54%,其他5种抑制剂均在10%左右。我们用9和10抑制剂确定它们对HepG-2细胞的IDO1的EC50。结果表明,9和10的EC50值分别问11.04μM,14.06μM。其他抑制剂的EC50值均超过100μM(表2)。
