Description
技术领域
本发明涉及医药技术领域,更具体地说,它涉及一种香草木宁碱在制备治疗类风湿性关节炎的药物中的应用。
背景技术
类风湿性关节炎(RA)是当前危害人类健康的最重要疾病之一,是一种病因未明的慢性、以炎性滑膜炎为主的系统性疾病。其特征是手、足小关节的多关节、对称性、侵袭性关节炎症,经常伴有关节外器官受累及血清类风湿因子阳性,可以导致关节畸形及功能丧失。类风湿关节炎在晚期、重症或长期卧床患者,因合并感染,消化道出血,心、肺或肾病变等可危机患者生命。
现行治疗类风湿性关节炎的方法主要有手术治疗、化学药物治疗和细胞因子类生物制剂的治疗。目前临床上治疗类风湿性关节炎的药物主要包括非甾类抗炎药、慢作用抗风湿药、免疫抑制剂、免疫和生物制剂及植物药等。非甾类抗炎药是类风湿关节炎治疗中最为常用的药物,有抗炎、止痛、解热作用,适用于活动期等各个时期的患者。常用的药物包括双氯芬酸、萘丁美酮、美洛昔康、塞来昔布等。尽管非甾类抗炎药一般能较好的耐受,但常合并潜在的临床毒性,尤其是长期使用时,副作用常与剂量相关。没有一种非甾类抗炎药是绝对安全的,好的疗效及安全性均是相对的,其常见的毒副作用:1、胃肠道副作用:与非甾类抗炎药抑制前列腺素有关,其减少了胃肠的血流,破坏了胃肠黏膜的保护机制,此外直接的胃肠刺激、对胃酸及血小板黏附力的影响均可引起溃疡及出血;2、抗凝作用:非甾类抗炎药通过抑制前列腺素、血栓素等的产生,使血小板黏附力减弱,同时也减少血小板对各种刺激的反应,从而导致抗凝作用;3、肝脏副作用:服用非甾类抗炎药治疗的患者可出现可逆性肝细胞损害,表现为肝氨基转移酶升高,停药后多恢复正常;非甾类抗炎药诱发严重的肝功能障碍较罕见,如出现则必须立即停药;4、肾脏副作用:非甾类抗炎药可抑制肾脏前列腺素的舒张血管作用,从而降低肌酐清除率,因而有低血容量和肾功能损害者应慎用,老年人使用时应特别注意;5、其他:包括各种过敏所致的皮疹、哮喘,白细胞减少等血液系统损害,耳鸣、听力下降、头痛、精神症状、甚至无菌性脑膜炎等各种中枢神经系统表现。针对这些不良反应,急需新型药物用于类风湿性关节炎,为患者提供更好的治疗方案。研究发现,中药及中药中分离纯化得到的天然化合物对类风湿关节炎具有较好的疗效,且副作用更小。
香草木宁碱:白色固体,英文名Kokusaginine,别名:6,7-Dimethoxy dictamnine,4,6,7-Trimethoxyfuro[2,3-b]quinoline-water;分子式:C14H13NO4分子量259.26,CAS登录号:484-08-2,熔点:171℃,可溶于氯仿、乙酸乙酯、丙酮、甲醇。可从花椒果皮中分离纯化得到的天然化合物,具有提高去甲肾上腺素和多巴胺水平(鼠大脑);光毒作用(啤酒酵母菌,白色念珠菌);杀虫、抗炎以及抑制人乳腺癌细胞及耐药株细胞增殖的作用;解痉挛作用。
在现有技术中,有研究人员曾发现熊果酸在治疗类风湿关节炎方面效果显著,其可通过抑制炎症因子的表达、调节免疫反应、骨保护、诱导滑膜成纤维细胞凋亡等多种途径发挥作用;还曾发现姜黄素能够抑制RA大鼠的踝关节炎性反应和破骨细胞激活,其机制与下调TLR4/NF-κB信号通路有关;还曾发现小檗碱对类风湿性关节炎具有潜在的治疗活性,并且与抑制OPG/RANKL/NF-κB信号有关;还曾发现高剂量白藜芦醇可以显著改善CIA小鼠的关节病变;还曾发现雷公藤红素能够有效缓解CIA小鼠的骨侵蚀作用,其机制可能是CSL激活Fas/FasL死亡受体途径诱导OCPs的凋亡并抑制OC分化,抑制骨破坏的发生。
但是,并未有香草木宁碱在治疗类风湿性关节炎方面,或用于在制备治疗类风湿性关节炎的药物中的报道;因此,本发明旨在提供一种香草木宁碱在制备治疗类风湿性关节炎的药物中的应用。

在本实施例中,凝胶基质采用壳聚糖:羧甲基纤维素钠1:19的比例组成,其中壳聚糖10份、羧甲基纤维素钠190份;表面活性剂采用烷基葡糖苷:椰油酰谷氨酸钠为1:1比例组成,其中烷基葡糖苷50份、椰油酰谷氨酸钠50份;保湿剂采用50份透明质酸。
具体制备步骤如下:
S1:将1份香草木宁碱与200份的去离子水搅拌混合,同时边搅拌边加入硅油、烷基葡糖苷和椰油酰谷氨酸钠,以600r/min的转速搅拌2h获得混悬液Ⅰ;
S2:在50℃的预设温度下,将50份透明质酸钠用200份去离子水稀释到预设比例,混合均匀得到混悬液Ⅱ;
S3:将混悬液Ⅰ和混悬液Ⅱ搅拌混合,同时边搅拌边加入10份壳聚糖和190份羧甲基纤维素钠,加入后继续以600r/min的转速搅拌3h,既得药物组合物(香草木宁碱凝胶)。
实施例2:香草木宁碱的作用位点
将香草木宁碱的SMILES数据输入Swiss Target Prediction(http://www.swisstargetprediction.ch/)在线靶点预测数据库,预测成分靶点;在Gene Card(http://www.genecards.org/)数据库中根据关键词类风湿性关节炎得到疾病靶点。将成分靶点与类风湿性关节炎靶点取交集,得到香草木宁碱潜在的抗类风湿性关节炎靶点。将香草木宁碱潜在的抗类风湿性关节炎靶点上传至STRING数据库(https://string-db.org)构建交集靶点蛋白互作网络,生物种类设定为人类。利用Cytoscape 3.9.0软件中进行聚类和拓扑分析,获得香草木宁碱潜在的抗类风湿性关节炎核心靶点(图4)。
香草木宁碱与核心靶点进行分子对接,在PubChem数据库中获取香草木宁碱的3维结构;在PDB数据库(https://www.rcsb.org/)获取关键靶点的3维结构,通过Autodock工具给蛋白受体加氢并确定活性口袋,最后,利用活性口袋中心区域的数值在Autodock Vina中进行分子对接,并通过PyMOL软件进行可视化处理(图5)。
结果显示,香草木宁碱与核心靶点SRC、PARP1、MAPK14结合良好。表1为香草木宁碱与各靶点的分子对接结合能结果。结合能<-5kcal/mol表示分子对接结果良好,表明香草木宁碱与类风湿性关节炎靶点对接良好。

图2为各组斑马鱼幼鱼的荧光显微镜照片,其中control表示空白组,CuSO4表示模型组,Ibuprofen表示阳性对照组,250ηg、500ηg和1000ηg表示三个不同浓度香草木宁碱组。图3为各组嗜中性粒细胞统计结果。
由图2和图3可知,香草木宁碱对硫酸铜诱导的斑马鱼急性炎症发生和扩散具有抑制活性,且具有良好的剂量依赖关系。
实施例4:香草木宁碱凝胶对类风湿性关节炎小鼠的治疗效果实验
选取20只雄性SD小鼠,体重170~200g,采用足趾内注射弗氏完全佐剂诱发抗原注射部位及其局部淋巴结的炎症反应,有利于刺激免疫细胞的增殖作用,建立类风湿性关节炎小鼠模型。每次0.2mL注射至左后足;先测定每只小鼠左后足的足趾厚度,将造模成功的小鼠分为模型组、给药组和甲氨蝶呤凝胶组,随机每组10只。给药组左后足涂抹香草木宁碱凝胶,模型组涂抹生理盐水,对比组涂抹含有甲氨蝶呤凝胶,每日1次,共涂抹2周。给药结束后,再次测定每只小鼠左后足的足趾厚度,取平均值,各组小鼠给药前及给药后足趾厚度测量结果如下:
表3
由上述结果可知,给药前后小鼠的足趾厚度无明显差异,模型组小鼠在给药前后足趾厚度增加,炎症明显加重。而给药组和阳性药组小鼠在两周给药后足趾厚度明显减小,且香草木宁碱组效果优于甲氨蝶呤组,这说明香草木宁碱对类风湿性关节炎有一定的抑制作用。
实施例5:香草木宁碱凝胶对类风湿性关节炎患者的作用
(1)实验方法
选择2022年8月-2022年10月,在医院确诊类风湿性关节炎并进行临床治疗的患者150例,将其随机分为给药组、对照组以及甲氨蝶呤凝胶组,每组50例。治疗组男29例,女21例;年龄19~65岁,平均(45.42±3.27)岁,病程0.2~11年,平均(4.21±0.13)年。对照组男17例,女33例;年龄24岁~70岁,平均(48.79±4.53)岁,病程0.5~8年,平均(3.97±0.54)年。甲氨蝶呤凝胶组男23例,女27例;年龄22岁~68岁,平均(46.79±3.45)岁,病程0.25~9年,平均(4.03±0.64)年。两组患者在年龄、性别和病程三方面比较,差异无统计学意义(P>0.05),具有可比性。
受试者知情,自愿签署知情同意书。并排除患恶性肿瘤、结缔组织疾病、血液系统疾病患者及妊娠、哺乳期妇女和病态窦房结综合征、急性心肌炎、高度房室传导阻滞、肝衰竭、肾衰竭、严重感染等患者。
分别将给药组与对照组设置如下:
给药组:将按照实施例1的方法制备的香草木宁碱凝胶涂抹患处,一日两次,两周为一个疗程,治疗三个疗程。
对照组:采用白云山的消炎镇痛膏,每日一帖,两周为一个疗程,治疗三个疗程。
甲氨蝶呤凝胶组:将按照实施例1的方法制备甲氨蝶呤凝胶涂抹患处,一日两次,两周为一个疗程,治疗三个疗程。
诊断标准以关节或肌肉无酸疼感、疼痛感,受累关节无疼痛,活动轻松,遇冷无疼痛,X射线检查无软组织肿胀,血沉正常,类风湿因子正常为痊愈;以关节或肌肉轻微酸痛感、疼痛感,受剋关节轻微疼痛,活动轻松,遇冷轻微疼痛,X射线检查无软组织肿胀,血沉正常,类风湿因子正常为有效;以症状无改善为无效。
(2)治疗结果
表4
通过以上临床治疗结果表明,本发明对类风湿性关节炎有明显的治愈效果,痊愈率为78%,总有效率为88%。
综上所述,本发明对类风湿性关节炎患者具有较好的治疗效果,为制备治疗抗类风湿性关节炎外用药物提供更多选择。
本具体实施例仅仅是对本发明的解释,其并不是对本发明的限制,本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改,但只要在本发明的权利要求范围内都受到专利法的保护。
