Description

辛可耐因Ib在制备治疗炎症性肠病的药物的应用
技术领域
本发明涉及一种天然产物的新用途,特别涉及一种辛可耐因Ib在制备治疗炎症性肠病的药物的应用。
背景技术
黄酮木脂素是一类新型的具C-9取代基的黄酮类化合物,即以黄酮和苯丙素类衍生物缩合而成的化合物,该类化合物具有很强的抗氧化、保肝、抗肿瘤、杀菌等生物活性[1]。辛可耐因Ib就是一种黄酮木脂素类化合物,来源于楝科鹧鸪花属巴西海木,蓼科菊三七属血三七,报春花科珍珠菜属珍珠菜,红树科红树属红海榄根、秋茄属秋茄,百合科菝葜属菝葜,蔷薇科枇杷属枇杷、苹果属苹果等6个科8个属植物中根、茎、果实、种子为原料。目前研究显示辛可耐因Ib具有较强的抗病毒[2]、抗氧化活性[3],能够促进胰岛素的分泌[4],但是其他的活性研究报道相对较少。
炎症性肠病(inflammatoryboweldisease;IBD)是一种慢性、复发性的肠道炎症疾病。近年来在发达国家,IBD的发病率已达到了1/1000[5]。到目前为止,IBD的病因还没有完全研究清楚,被认为是基因,环境,微生物和机体免疫系统的相互作用造成的[6]。由于确切的病因不清,常规的治疗策略主要是抗炎和非特异性的抑制免疫反应[7]。但大剂量的非甾体抗炎药物的使用会产生高热、消化不良、腹泻、转氨酶升高、脂酶水平升高等不良反应,皮质激素和免疫抑制剂的长期使用也会产生剂量依赖性。近年来,学者开始关注中药及天然产物治疗炎症性肠病,研究表明中药及天然产物的疗效稳定,且具有综合性双向调节作用,既可调节免疫功能又能抵御病原微生物的侵袭,并可减轻或缓解症状等优点。本发明通过实验证明辛可耐因Ib可以对抗炎症性肠病的发生,增加了辛可耐因Ib的新用途。

具体实施方式
下面结合具体实施例对本发明作进一步的说明。
实施例1
辛可耐因Ib的制备方法
(1)提取:200g苹果多酚(天津市尖峰天然产物研究研究开发有限公司提供,多酚含量80%)中加入2000mL的水常温搅拌溶解,备用;
(2)大孔树脂吸附分离:将(1)中苹果多酚溶液经HP20型大孔树脂吸附,用水、体积百分比浓度为10%、30%、50%、70%、95%的乙醇水溶液梯度洗脱,每半个柱床体积作为一个接收体积,通过薄层层析方法并结合分析型HPLC检测,收集富含辛可耐因Ib的组分,将其合并,在温度≤60℃,真空度为0.06~0.08MPa减压浓缩,糖度为40,得辛可耐因Ib的富集物;
(3)硅胶柱分离:大孔树脂吸附分离后得到的辛可耐因Ib的富集物用等倍量的甲醇溶解以1.5--2.5倍量比例加入60-100目硅胶减压拌样至干,干法上样,用10-20倍量的硅胶柱色谱分离,用二氯甲烷-甲醇体积比为95:5,93:7,92:8,91:10梯度洗脱,半个柱床体积作为一个接收体积,通过薄层层析方法并结合分析型HPLC检测,收集富含辛可耐因Ib的组分,将其合并,在温度≤60℃,真空度为0.06~0.08MPa减压浓缩至干,得辛可耐因Ib的富集物,含量为32.1%;
(4)Toyopearl HW-40分离:将辛可耐因Ib富集物用2倍水溶解,经Toyopearl HW-40 柱色谱分离,用甲醇-水的体积比为10%,15%,20%,25%梯度洗脱,每四分之一个柱床体积作为一个接收体积,通过薄层层析方法并结合分析型HPLC检测,收集富含辛可耐因Ib 的组分,将其合并,在温度≤60℃,真空度为0.06~0.08MPa减压浓缩,糖度为20,得辛可耐因Ib的富集物,含量为67.2%;
(5)制备液相色谱精制:将(4)中辛可耐因Ib的富集物利用制备液相色谱精制,Cosmosil ODS柱(5u,10×250mm)254nm检测,50%甲醇水分离,收集辛可耐因Ib的色谱峰,并将其在温度≤60℃,真空度为0.06~0.08MPa减压浓缩,糖度为16,冷冻干燥得到辛可耐因Ib(460mg)。
利用ESI-MS、1H-NMR和13C-NMR等光谱手段并于文献数据进行对照,鉴定了根据上述方法分离得到的辛可耐因Ib的结构。在此基础上利用HPLC的面积归一化进行标定,辛可耐因Ib含量为97%。辛可耐因Ib淡黄色粉末,聚酰胺薄膜以正丁醇-醋酸-水(4:1:3) 展开,Rf为0.4,5%三氯化铁乙醇溶液显单一蓝色斑点。HR ESI-MS:(negative)m/z: 451.0986[M-H]-,计算值(451.1035),可以确定该化合物的分子量为452。结合氢谱碳谱给出的信息,确定其分子式为C24H20O9,计算其不饱和度为15。其1H-NMR(300MHz,in DMSO)中信号交叠较严重,其13C-NMR(75MHz,in DMSO)中信号清晰,与文献相对照进行了全归属,鉴定为辛可耐因Ib,结果见附图1
实施例2
辛可耐因Ib对葡聚糖硫酸钠致小鼠实验性结肠病作用。
实验方法:
(1)葡聚糖硫酸钠(dextran sulfate sodium,DSS)溶于蒸馏水配制成3%DSS(W/V)水溶液,即配即用。40只c57小鼠随机分为6组:正常对照组、模型组、辛可耐因Ib(实施例2 制备)高、中、低剂量组(200、100、50mg/kg)和阳性药物组(柳氮磺嘧啶组,220mg/kg),每组各8只。除正常对照组外,上述各组小鼠均给予3%DSS溶液自由饮用,造模开始分别按上述剂量灌胃给药,正常组和模型组给予等量体积生理盐水。记录每天每只小鼠DSS的应用量,确保各组DSS饮用量大致相等。每日观察小鼠一般状态和体重变化,观察粪便性状改变及便血情况,根据Cooper HS评分标准,进行疾病活动指数(Disease activity index, DAI)评分,评估小鼠结肠粘膜炎症损伤情况。评分标准:体质量不下降者记0分,下降 1%~5%为1分,下降5%~10%为2分,下降10%~15%为3分,下降>15%为4分;大便正常为0分,松散为2分,稀便为4分;大便潜血正常为0分,弱阳性为1分,阳性为2 分,强阳性为3分,肉眼血便为4分。实验进行8d后,处死小鼠,取下结肠,4%中性福尔马林固定,石蜡包埋切片后进行HE染色,镜下观察肠黏膜损伤情况,根据Cooper HS评分标准,观察15个放大100倍视野,取平均值,观察组织学损伤评分。评分标准:正常结肠黏膜者为0分;结肠隐窝腺体丢失三分之一者为1分;隐窝腺体丢失三分之二者为2分;若隐窝腺体全部丢失,黏膜上皮完整,伴有轻度炎性细胞浸润者为3分;黏膜上皮糜烂、破坏,伴有明显炎性细胞浸润者为4分。
实验结果:
正常对照组小鼠活动自如,反应灵敏,大便正常,毛色光泽,体重增加;模型组小鼠饮用3%DSS 8d后出现稀便、血便或脓血便、大便潜血实验阳性,体重减轻,活动进食均减少;各给予辛可耐因Ib组和阳性药物组小鼠状况好于模型组,其腹泻、便血症状较模型组明显减轻。DAI评分显示模型组组小鼠DAI升高,与正常对照组相比,具有统计学意义 (P<0.05),阳性药物组和辛可耐因Ib各组DAI评分明显降低,与模型组相比,差异具有统计学意义(P<0.05)。
光镜下观察正常组小鼠结肠黏膜完整连续,腺体排列规则整齐,无炎细胞浸润和溃疡形成。而模型组小鼠结肠充血水肿,粘膜丧失,糜烂、溃疡、出血,腺体排列紊乱,可见大量炎细胞浸润,说明造模成功。阳性药物组和辛可耐因Ib各组症状改善明显,结肠黏膜较完整,有轻度充血水肿和少量炎细胞浸润,肠腺体排列基本规则,组织学评分示,各治疗组组织学评分显著低于模型组,差异具有统计学意义(P<0.05)。上述实验结果说明辛可耐因 Ib能够明显抑制葡萄酸葡聚糖硫酸钠致小鼠实验性结肠病。
各实验组DAI评分和组织学评分比较(n=8,x±s)如附图2
注:与正常组比较,为P<0.05;与模型组比较,*为P<0.05
(2)免疫组化法检测相应蛋白的活性
常规梯度脱水,石蜡包埋切片,脱蜡水化,过氧化氢灭活内源性酶,PBS冲洗,枸橼酸盐缓冲液热抗原修复,PBS冲洗,加一抗,稀释度为1:100,PBS作为阴性对照,4℃湿盒过夜。PBS洗涤后,加入生物素化羊抗兔IgG二抗,37℃,30min,PBS洗涤,DAB显色,常规脱水、封片。实验结果见附图3。正常组小鼠结肠粘膜仅微弱表达NF-kB p65。而模型组中NF-kBp65显著增加,其阳性药物组NF-kBp65的表达收到明显抑制,二者相比,差异具有统计意义(P<0.05)。各给予辛可耐因Ib的治疗组NF-kBp65表达均减少,可耐因Ib高、中剂量组降低最明显,与模型组相比,差异具有统计学意义(P<0.05)。上述结果说明辛可耐因Ib能够有效降低炎症通路中NF-kB和Ikkα/β的表达,说明辛可耐因Ib能够调节炎症通路中相关蛋白的表达而发挥抗炎作用。
(3)ELISA法检测TNF-a、PGE2和IL-4的表达水平
摘取结肠组织匀浆离心后,采用酶联免疫吸附法,严格按照试剂盒说明,检测细胞因子TNF-a、PGE2和IL-4的水平。实验结果见附图4。
实验结果:
模型组TNF-a和PGE2水平升高,与正常组相比有统计学差异(P<0.05)。阳性药物组和辛可耐因Ib(实施例2制备)各组TNF-a和PGE2水平与模型组相比显著下降(P<0.05),其中TNF-a水平随着给药剂量的增加逐渐降低,呈剂量效应关系。各治疗组IL-4水平略有升高趋势。结果见附图4。
结肠组织IL-4、TNF-a和PGE2的含量比较(n=8,x±s)见附图4
注:与正常组比较,为P<0.05;与模型组比较,*为P<0.05
上述实验结果说明辛可耐因Ib能够明显抑制葡萄酸葡聚糖硫酸钠致小鼠实验性结肠病,并且能够提供机体的自身免疫能力,对抗炎症性肠病的发生。
实验证明:辛可耐因Ib可以对抗炎症性肠病的发生。
按常规方法将辛可耐因Ib成硬胶囊剂、软胶囊剂、散剂、颗粒剂、片剂、丸剂、蜜膏剂、口服液、栓剂、酒剂或注射剂的剂型,可以方便药物的使用。
