Description
技术领域
本发明属于药物化学领域,具体涉及一种含酰胺结构的没食子酸甲酯类似物及其制备方法和应用。
背景技术
炎症作为一种重要的病理过程在人体中十分常见,它本身是作为机体对于外来的或者异体的刺激的一种自身免疫应答。而当这种应答失调或者过分应答导致机体的自损伤时,就演变成了炎症。所以大多数的疾病都伴随着炎症的介导和发生,而炎症的介导和发生又使得疾病对于机体的损伤加重,如急性肺损伤、风湿性关节炎、糖尿病合并症、癌症、动脉粥样硬化、炎性肠病等。在这些过程中,促炎因子如TNF-α、IL-6、IL-1β等都起到了重要的作用。目前现有技术中针对炎症的治疗药物较多,也出现了大量的药物改进技术,其中针对查尔酮类似物的发明及研究,成为本领域技术人员的重要研究领域。
没食子酸甲酯(MG)是一种在各种植物和天然产物中发现的多酚,其在草药中可能存在显着的生物效应,如抗氧化、抗肿瘤、抗菌和抗炎活性。尽管没食子酸甲酯(MG)已被证明对多种炎症性疾病有益,但MG在ALI中的效力和功能尚未确定。因此,我们在此报道了一系列新颖的没食子酸甲酯衍生物(MGDs)的设计,合成和抗炎评价。此外,进行初步结构反应性关系分析,以概述没食子酸机制类似物的结构对其药理活性的影响。

步骤a合成3,4,5-三(苄氧基)苯甲酸(2):将没食子酸(500mg,2.94mmol)和K2CO3(3.66g,26.45mmol)溶解在DMF中在室温下搅拌1小时。在40℃,氮气保护下,在30分钟内将BnBr(4.19ml,35.27mmol)滴加到该溶液中。将反应混合物在40℃下搅拌12h,然后加入H2O(20ml)和EtOAc(3×30mL),萃取三次,合并有机层,将有机层用水(3×30mL)洗涤,用MgSO4干燥并减压浓缩。将残余物溶于含有5M NaOH的含水乙醇(50%,40ml)中并回流12小时。该溶液用H2O(40ml)稀释,用浓HCl调节至PH并在室温下搅拌30分钟。然后过滤得白色固体2(1.02g,产率79%,白色固体)。
步骤b合成酰胺3a-n的一般过程:在室温下,取3,4,5-三(苄氧基)苯甲酸(2)(0.3g,0.68mmol),将HATU(0.26g,0.68mmol)和DIPEA(0.24mL,1.36mmol)在无水CH2Cl2(10mL)的溶液中搅20分钟,缓慢加入取代的苯胺或含有不同取代基的苄胺(0.68mmol)。将反应混合物在室温下搅拌5小时。加水(10ml)淬灭,旋干CH2Cl2并用EtOAc(3×10mL)萃取。将合并的有机层用盐水洗涤并经无水MgSO4干燥,过滤并减压浓缩。将残余物从MeOH-H2O(1:1)溶液中重结晶,得到酰胺3a-n(产率80.2%-88.5%)。

化合物合成总路线如下式b:
类型II中的化合物(7a-r、9a-g)的合成步骤(步骤d-步骤e):
步骤d在冰浴条件下,在CH2Cl2(20mL)中依次加入各种取代的羧酸5a-r(1.2mmol),EDC·HCl(1.3mmol)和HOBT(1.5mmol)搅拌20分钟后,缓慢加入溶解在CH2Cl2中的5-氨基茚旦(6,160mg,1.2mmol),将反应混合物在冰浴中搅拌1小时,转移至室温搅拌过夜。所得混合物用H2O(20ml)淬灭,旋干溶剂并用饱和食盐水和EtOAc(3×20mL)萃取。合并的有机层并经无水MgSO4干燥,过滤并减压浓缩。通过硅胶色谱纯化残余物,得到目标化合物7a-r。
步骤e将含不同取代基团的肉桂酸8a-g(1.0mmol)溶解在无水THF(10mL)溶液中缓慢加入草酰氯(5.0当量)和催化量的DMF(0.01当量)。将反应体系在室温下搅拌5小时,真空旋干除去溶剂。将残余物重新溶于CH2Cl2(10mL)中,缓慢加入Et3N(3.0当量),5-氨基茚旦(1.0mmol),将反应混合物在室温下搅拌2小时并通过TLC监测。反应完成后,用H2O(20ml)淬灭,并用CH2Cl2(3×20mL)萃取。将合并的有机层用盐水洗涤并经无水MgSO4干燥,过滤并减压浓缩。通过硅胶色谱纯化残余物,得到目标化合物9a-g。

实施例40本发明的含酰胺结构的没食子酸甲酯类似物对脂多糖(LPS)刺激巨噬细胞释放炎症因子的抑制的活性
将本发明实施例1~39制备出的化合物刺激RAW 264.7巨噬细胞释放炎症因子(TNF-α和IL-6),抑制的方法测试了化合物的体外初步抗炎活性,具体方法如下:1.2×106个RAW 264.7巨噬细胞用DMEM培养液培养于37℃,24小时后更新培养液,并加入受测化合物(终浓度为10μM)预处理2小时,再用0.5μg/mL的LPS继续处理22小时,收集培养液用ELISA法检测TNF-α和IL-6含量;收集细胞检测总蛋白浓度,ELISA结果用相应的总蛋白浓度相除较准,以LPS对照组的TNF-α和IL-6含量定标为100;每个化合物重复测试3次,计算平均值和误差值。测试时用阳性药物黄腐酚做对照。化合物对TNF-α和IL-6释放的抑制活性见图2所示,从该图可以看出本发明的没食子酸甲酯类似物对脂多糖(LPS)刺激RAW 264.7巨噬细胞释放IL-6和TNF-α的抑制活性,其中,相对含量越低,代表抑制活性越强。
本发明实施例1~39制备出的以水解没食子酸甲酯酯键为母核结构的没食子酸甲酯类似物大部分化合物均具有对IL-6释放的抑制活性,对于TNF-a的释放具有较好的抑制效果的是4k、7f、7l、7r;而阳性化合物没食子酸甲酯活性不佳,不具有药用前景。
实施例41实施例11、20、26、32制备出的4k、7f、7l、7r抑制LPS刺激RAW 264.7巨噬细胞释放IL-6和TNF-α的量效关系
进一步测试了实施例11、20、26、32制备出的4k、7f、7l、7r抑制LPS刺激RAW 264.7巨噬细胞释放TNF-α和IL-6的量效关系,方法:同实施例11。实验数据见图3。化合物4k、7f、7l、7r对TNF-α和IL-6的抑制活性均具有较好的量效关系。见图3所示为本发明化合物4k、7f、7l、7r抑制LPS刺激RAW 264.7巨噬细胞释放IL-6和TNF-α的量效关系。
实施例42实施例11制备出的4k抑制LPS刺激的巨噬细胞中的mRNA的表达
为了确定LPS诱导的巨噬细胞的减少是否与转录抑制有关,通过实时定量PCR(RT-qPCR)方法测定TNF-α,IL-6,细胞间粘附分子1(ICAM-1),VCAM-1,MCP-1的信使RNA。用LPS(1.0mg/mL)处理巨噬细胞6小时,用化合物4k处理或不用化合物处理前炎症基因的表达。结果总结在图4A-E中,清楚地表明它们的TNF-α,IL-6,ICAM-1,VCAM-1,MCP-1均下调。化合物4k能有效下调TNF-α,IL-6,ICAM-1,VCAM-1,MCP-1的表达,具有统计学意义。这些数据提供了没食子酸甲酯类似物4k的抗炎作用和影响mRNA水平的证据。
