一种芳基内酰胺环类化合物、药物组合物及其应用
技术领域
本发明涉及药物化学技术领域，具体涉及一种芳基内酰胺环类化合物、药物组合物及其应用。
背景技术
缺氧诱导因子-1(hypoxiainduciblefactor-1，缺氧诱导因子-1)是一种普遍存在于人和哺乳动物细胞内的转录因子，在缺氧条件下，缺氧诱导因子-1的α与β亚基形成异二聚体后进入细胞核中，与下游靶基因启动子的缺氧反应元件(HREs)结合，并激活基因转录。缺氧诱导因子-1的下游靶基因相当广泛，参与了包括血管生成和恶性肿瘤细胞获得迁移侵袭能力的生物学过程(上皮间质转化，EMT)。
恶性肿瘤生长旺盛，处于缺氧状态，可激活缺氧诱导因子-1α，促进了下游多种基因的转录和表达，包括血管表皮生长因子(VEGF)、基质金属蛋白酶(MMPs)、葡萄糖转运蛋白(GLUT1)、上皮-间质转化(EMT)相关转录因子snail、twist等，通过促进血管生成、肿瘤代谢重编程、EMT、免疫逃逸、凋亡抑制等多个途径，增强了肿瘤的侵袭转移能力和放化疗抵抗性，促进肿瘤的发生发展和转移。
视网膜微血管网的渐进性损伤导致组织缺血、缺氧诱导因子-1上调、VEGF分泌的刺激，最终导致了视网膜血管病理性生长以及各种相关疾病，包括早产儿视网膜病变、糖尿病视网膜病变、年龄相关性黄斑变性和视网膜静脉阻塞、高血压性视网膜病变和视网膜动脉阻塞等,这些疾病是视力丧失的主要原因。
因此，缺氧诱导因子-1可以作为治疗恶性肿瘤、特别是转移性恶性肿瘤，以及视网膜血管病理性生长相关疾病的药物作用靶点。缺氧诱导因子-1抑制剂可以抑制VEGF水平、抑制新生血管生长、抑制细胞侵袭和迁移能力，从而对恶性肿瘤、特别是转移性恶性肿瘤，以及视网膜血管病理性生长相关疾病起到预防和治疗作用。
但目前临床上缺少以缺氧诱导因子-1为靶点，用于治疗和预防转移性恶性肿瘤以及视网膜血管病理性生长相关疾病的药物。
鉴于上述缺陷，本发明创作者经过长时间的研究和实践终于获得了本发明。
发明内容
本发明的目的在于解决临床上缺少以缺氧诱导因子-1为药物作用靶点，用于预防和(或)治疗转移性恶性肿瘤和(或)视网膜血管病理性生长相关疾病的药物的问题，提供了一种芳基内酰胺环类化合物、药物组合物及其应用。
为了实现上述目的，本发明公开了一种芳基内酰胺环类化合物，具有以下通式：
其中，X选自-CH2-、-O-、-CH2CH2-、-OCH2-；Ar1选自以下芳香环或芳香环系：
Ar2选自以下芳香环或芳香环系：
所述芳基内酰胺环类化合物为以下任意一种化合物：
所述芳基内酰胺环类化合物在人肝微粒体代谢中，具有药物开发所需的理想的稳定性。
本发明还公开了包含上述芳基内酰胺环类化合物的药物组合物，还包括药学上可以接受的辅料。
本发明还公开了上述芳基内酰胺环类化合物在制备预防和/或治疗缺氧诱导因子-1上调导致的疾病的药物中的应用；所述疾病包括乳腺癌、卵巢癌、肺癌、肝癌、宫颈癌、胃癌、肠癌以及视网膜血管病理性生长疾病。本发明公开的代表性化合物通过阻断缺氧诱导因子-1信号通路，从而抑制了肿瘤细胞的侵袭和转移能力，可以作为预防和(或)治疗恶性肿瘤的药物或药物组合物。同时，本发明公开的代表性化合物通过阻断缺氧诱导因子-1信号通路，抑制了血管表皮生长因子VEGF的信使RNA，因此，可以作为预防和(或)治疗与血管病理学生产相关疾病的药物或药物组合物。在人肝微粒体代谢检测实验中，与已公开的芳基甲酰胺类化合物相比，本发明所公开的代表性化合物具有适宜的代谢稳定性，而具有适宜的代谢稳定性是成为药物的前提条件。
与现有技术比较本发明的有益效果在于：本发明公开的芳基内酰胺环类化合物的化学结构与已有的缺氧诱导因子-1抑制剂均不相同，是一类全新结构的缺氧诱导因子-1抑制剂。此外，与公认的缺氧诱导因子-1抑制剂LW-6相比，本发明公开的芳基内酰胺环类化合物具有更强的抑制作用。与已公开的芳基甲酰胺类缺氧诱导因子-1抑制剂的化学结构相比，本发明公开的化合物在化学结构上，对其酰胺部分进行环合，形成了二氢异喹啉酮、苯并氮杂酮、苯并二氢噁嗪酮和苯并二氢氧氮杂/>酮四个类别的新型缺氧诱导因子-1抑制剂。与芳基甲酰胺类缺氧诱导因子-1抑制剂的代谢稳定性相比，本发明公开的芳基内酰胺环类化合物具有更好的代谢稳定性，在肝微粒体酶存在的条件下，半衰期比芳基甲酰胺类代表性化合物AMSP-30m提高了16～45倍。虽然环合是药物化学中结构改造的一种方法，但在实施之前并不能预测环合之后是否能够保持对缺氧诱导因子-1的抑制作用，以及是否可以增加代谢稳定性。因此，本发明所公开的化合物具有明显的新颖性和创造性，这种芳基内酰胺环类化合物，在细胞学实验中对缺氧条件下缺氧诱导因子-1信号通路具有较好的抑制作用，同时，对人肝微粒体酶代谢酶具有适宜的代谢性质，在制备预防或治疗抗肿瘤或抗视网膜血管性病变的药物上，具有良好的预防或治疗效果，并有一定的成药性。

以下对实施例1～61制备的化合物的性能进行检测：
1、实施例1～61制备的化合物对HIF-l信号通路的抑制作用
将人肝癌细胞LM3接种到24孔板中。根据说明书，使用Lipofectamine2000转染试剂(Invitrogen公司产品)将含有5个拷贝的HIF-1结合元件(HRE)的萤火虫荧光素酶(fireflyluciferase)报告基因质粒(pGL3-HRE-Luc)和编码海肾荧光素酶(renillaluciferase)的pRL-SV40质粒共转染进入细胞。然后在常氧(21％O2)下孵育6小时。随后，将每孔的培养基换成含有DMSO(阴性对照)或10μM受试化合物的新鲜培养基，并将板在常氧条件下培养1小时后，在缺氧(1％O2)再孵育24小时。用PBS缓冲液洗涤细胞后，根据说明书，使用双荧光素酶报告基因测定试剂盒(Promega)和酶标仪(SpectraMaxM4，MolecularDevice)测量测定荧光素酶活性。萤火虫荧光素酶活力数值用海肾荧光素酶活力数值化归一(公式1)。以DMSO组(阴性对照)的抑制率为0％，计算受试化合物对荧光素酶的抑制率(公式2)，计算结果如表1所示。

2、肝微粒体酶代谢法检测实施例9、10、14、17、19、36、53、56制备的化合物的稳定性
实验在100mmol/L磷酸盐缓冲液(pH＝7.4)中进行，在37℃的条件下将最终浓度为1mg/mL的人肝微粒体蛋白质和终浓度为100μmol/L的底物预热10分钟，反应由加入终浓度为1mmol/L的NADPH启动。在37℃孵育条件下摇动反应液，并分别在0、5、15、30、45、60、90和120分钟时取样100μL，加至含有400μL冰乙腈的聚丙烯管中以停止反应，将混合液于12000r/min离心10min，取上清液，用于UPLC分析。处理液在254nm的UV波长下使用WONDASILC18色谱柱(4.6×150mm)，实验使用SHIMADZU的LC-20A HPLC系统，在30％水和70％的乙腈(含0.1％甲酸(条件下，以1mL/min的流速实现梯度洗脱20分钟进行分析检测(见表2)。

3、实时PCR法检测检测实施例9、10、14、17、19、36、53、56制备的化合物的对缺氧诱导的血管表皮生长因子(VEGF)信使RNA(mRNA)的影响
VEGF是HIF-1调控的下游基因。HIF-1α和HIF-1β的二聚体结合于VEGF基因的启动子序列上，推动了其转录，因此我们检测HIF-1抑制剂实施例51化合物是否能抑制缺氧诱导的VEGF基因转录，即VEGF的mRNA的增加。具体操作方法如下：人脐静脉内皮细胞(HUVEC)在常氧条件下用实施例9、10、14、17、19、36、53、56制备的化合物或DMSO(阴性对照)分别处理1小时，再在缺氧条件下处理24小时。使用TRIzol试剂(Invitrogen公司产品)提取总RNA，并使用primescriptRT试剂盒(Takara公司产品)进行逆转录以获得cDNA，随后使用SYBRPremixExTaqII(Takara公司产品)通过实时PCR扩增。通过2-ΔΔCt方法计算基因表达，并以GAPDH为内参，计算相对表达水平。结果表3所示，实施例9、10、14、17、19、36、53、56制备的化合物可以不同程度对VEGFmRNA水平产生抑制作用。所述的常氧条件是指氧气在细胞培养箱中所占的比例约是21％，缺氧条件是指氧气在细胞培养箱中所占的比例是1％。

Transwell小室的底部有一层含有小孔的膜，孔径8μM。在小室膜表面预先包被一层基质胶，模拟体内的基底膜。无血清培养基混悬的细胞接种于细胞基质胶表面，并将小室置于含有血清的培养基中，由于血清中细胞因子的趋化作用，细胞通过侵袭穿过基质胶，再穿过小室底部含有小孔的膜，至膜背面，以先侵袭再迁移穿过小孔至膜背面的细胞数目表征细胞的侵袭能力。观察细胞侵袭时，具体操作如下：将2×105个MDA-MB-231细胞悬浮在每孔0.3mL无血清培养基中，接种到Transwell小室(Corning公司产品)中。对于侵袭测定，小室内预先包被基质胶(matrigel，Corning公司产品)。将小室置于24孔板中，并在下部孔板中加入含有10％FBS和实施例9、10、14、17、19、36、53或56制备的化合物或DMSO(阴性对照)的完全培养基。将孔板在常氧条件下孵育1小时并在低氧条件下再孵育24小时。用棉签将小室上表面未迁移穿过小孔的细胞擦去，迁移过小孔至膜背面的细胞用甲醇固定，结晶紫染色，随后在倒置显微镜下从每个孔的5个不同区域计数，取平均数，并与阴性对照组细胞平均数的比值计算抑制率。
