Description
技术领域
本发明涉及生物医学技术领域,具体涉及连翘苷在制备脂肪甘油三酯脂肪酶抑制剂中的应用。
背景技术
连翘始载于《神农本草经》卷三,列为下品,曰:“连翘一名异翘,一名兰华,一名折根,一名轵,一名三廉。生山谷”。其味苦,性微寒。归肺、心、小肠经,主产于我国山西、河南、陕西、山东等地。2020年版《中华人民共和国药典》收载连翘为木犀科植物连翘Forsythiasuspensa(Thunb.)Vahl的干燥果实。秋季果实初熟尚带绿色时釆收,除去杂质,蒸熟,晒干,习称“青翘”;果实熟透时采收,晒干,除去杂质,习称“老翘”。具有清热解毒,消肿散结,疏散风热的功效,临床上用于治疗痈疽,瘰疬,乳痈,丹毒,风热感冒,温病初起,温热入营,高热烦渴,神昏发斑,热淋涩痛。
连翘中含多种化学成分,主要包括木脂素类、黄酮类、苯乙醇苷类、挥发油类及萜类、生物碱类、有机酸类等,其中木脂素类有效活性成分连翘苷(Phillyrin,分子量为534.55)含量较高,是连翘的主要药理活性成分,也是中国药典所规定的连翘质量控制指标性成分,中国药典规定本品按干燥品计算,含连翘苷(C27H34O11)不得少于0.15%。连翘苷是由两分子苯丙素侧链相互连接形成两个环氧结构的一类木脂素,其结构上连翘是多种天然产物单体发挥抗氧化、抗菌和抗炎作用的重要基团之一。
脂肪甘油三酯脂肪酶(Adipose triglyceride lipase,ATGL)是催化甘油三脂水解第一步的重要脂肪酶,将甘油三酯水解为甘油二脂和一分子游离脂肪酸,是脂滴中甘油三脂水解的主要限速酶。ATGL在细胞质、脂滴和细胞膜上都有分布,ATGL借助C-端Val315到Ile364的疏水区域结合到脂滴表面。
连翘苷是中药连翘的主要的活性成分之一,现代药理研究表明连翘苷具有多种作用,包括抗氧化、抗炎、抑制肥胖、调节代谢等。连翘苷的一些药理作用已经被研究者证明:有研究表明连翘苷通过抑制MAPKs以及NF-κB通路的激活,从而改善TNFα诱导的体外脂肪细胞的炎症反应。连翘苷通过激活脂肪组织PPARγ/ANPTL通路,降低小鼠血清炎症因子如TNFα的表达,改善高脂饮食导致的脂肪组织慢性炎症状态,从而改善高脂诱导的胰岛素抵抗。此外,连翘苷激活IRS/PI3K/AKT信号通路,改善脂肪细胞胰岛素敏感性,显著增强脂肪细胞对葡萄糖的摄取率。
目前报道的ATGL抑制剂只有Atglistatin。因此,急需开发出效果好且副作用较小、价格适宜的药物。
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现有的脂肪甘油三酯脂肪酶抑制剂的效果欠佳且有副作用的问题,提供了连翘苷在制备脂肪甘油三酯脂肪酶抑制剂中的应用。
为了实现上述目的,本发明公开了连翘苷在制备脂肪甘油三酯脂肪酶抑制剂中的应用,所述抑制剂剂型为注射剂、丸剂、片剂、颗粒剂中的任意一种。
与现有技术比较本发明的有益效果在于:本发明采用连翘苷作为ATGL抑制剂,通过抑制脂肪组织脂解过程及其在相关代谢紊乱疾病中的应用,通过一系列相关实验,发现连翘苷可显著降低高脂饲养或正常小鼠血清游离脂肪酸和甘油水平,抑制脂肪组织基础脂解反应,降低ATGL的基因表达和蛋白水平。分子对接实验表明,连翘苷可与ATGL蛋白进行结合,并产生抑制作用。连翘苷作为ATGL抑制剂,其实验结果可靠,效果明确。

八、连翘苷与ATGL蛋白的分子对接
ATGL预测蛋白结构(Q8BJ56(PLPL2_MOUSE))从AlphaFold Protein StructureDatabase(www.alphafold.ebi.ac.uk)上下载。运用Schrodinger software release2017-1软件进行分析计算。运用LigPrep module(https://www.schrodinger.com/)获取连翘苷和Atglistatin的3D构型,并运用OPLS3 force field进行优化。运用Sitemap软件预测蛋白结合位点。运用Glide SP进行连接评分。
九、实验结果
1、连翘苷降低小鼠血中甘油水平
如图1A结果显示,与模型组相比,25mg/kg连翘苷连续给药后,可显著降低高脂饲养小鼠血中甘油水平。此外,单次给药,连翘苷可呈剂量依赖性的降低小鼠血中游离脂肪酸(FFAs)的水平(图1B)。上述结果提示,连翘苷可抑制脂肪组织基础水解过程。
2、连翘苷抑制体外脂肪组织基础脂解反应
如图2A结果显示,与LPS组相比,200μM连翘苷可显著降低脂肪组织甘油的释放。同时,如图2B结果显示,与IL-6组相比,200μM连翘苷可显著降低脂肪组织甘油的释放。上述结果提示,连翘苷可降低脂肪组织基础水解反应。然而,在ATGL被其抑制剂Atglistatin抑制的情况下,200μM连翘苷不能够显著降低脂肪组织的甘油释放水平(图2C)。因此,连翘苷对脂肪组织脂质水解的抑制作用与ATGL相关。
3、连翘苷降低ATGL基因的表达
RNA-seq数据显示连翘苷可显著改变脂肪组织的基因表达水平(图3)。其中,脂质水解通路中ATGL的表达显著降低,而CGI-58、HSL及MGL表达水平不变(图4)。通过qRT-PCR实验,我们进一步证实脂质组织中ATGL mRNA水平显著降低(图5)。因此,上述结果显示连翘苷可抑制脂肪组织ATGL的基因表达。
4、连翘苷降低ATGL蛋白的表达
Western blot结果显示,连翘苷可显著降低IL-6刺激的脂质组织中ATGL的蛋白水平。而其他相关蛋白(PLIN1、pHSL、HSL、CGI-58)的表达水平不受连翘苷影响(图6)。因此,上述结果显示连翘苷可抑制脂肪组织ATGL的蛋白表达。
5、连翘苷与ATGL蛋白分子对接实验结果
连翘苷与ATGL有5个可能的结合位点(表1)。其中,位点2的评分最高,达到-12.70,高于Atglistatin在此位点的评分。因此,我们选取位点2用来进行连翘苷与ATGL建立分子对接模型。结果显示,连翘苷有5个氢键能与ATGL Ser47、Leu51、Thr146、Ala225和Leu226号位点的氨基酸形成氢键(图7)
