背景技术
红毛七为小檗科植物类叶牡丹(Caulophyllum robustum Maxim.)的根及根茎,又名红毛漆、金丝七、类叶牡丹、藏严仙、海椒七、鸡骨升麻等。红毛七主要产于黑龙江、陕西、辽宁、甘肃、湖北等地,生长在海拔高约950-3500米的山沟阴湿处,林下或竹林下。其在湖北省作为一种土家族特色民族药,根及根茎作为药物使用,具有祛风除湿、清热解毒、活血化瘀、降压止血、行气止痛等功效,主要被用于治疗风湿麻痹、月经不调、跌打损伤、胃痛、腹痛等其他疾病。现代研究表明,红毛七中含有三萜、生物碱、倍半萜、环烯醚萜、酚酸等物质,药理实验研究发现红毛七具有抗炎镇痛、抗风湿、抗肿瘤、抗氧化、抗菌、降低血糖等作用。
在中国专利公开文献中,由四川省汶川县威州镇羌医骨伤科医院申请的公开号为CN1319408A的发明专利申请公开了一种红毛七与其他药材配伍的药酒,用于治疗跌打损伤。公开号为CN109966354A的发明专利申请公开了一种红毛七三面刀活血散瘀贴及其制备方法,主治劳伤、腰腿痛带来的疼痛。公开号为CN103211976A的发明专利申请公开了一种红毛七与其他药材配伍的外用中药制剂的制备方法,是治疗痛风的良方。由北京和润创新医药科技发展有限公司申请的公开号为CN101697991A发明专利申请公开了一种从中药红毛七提取液中分离总生物碱的方法,其提取方法为取红毛七提取液,调整pH值为1至7,滤过,取滤液加于阳离子交换树脂柱上,先以水洗脱除杂,再以0.5%~20%的盐溶液浸泡树脂柱,再以含酸或乙醇的0.5%~20%盐溶液洗脱,检查无生物碱为止,收集洗脱液,加碱中和,经脱盐处理,浓缩干燥得中药红毛七总生物碱。公开号为CN1800187A的发明专利申请公开了一种塔斯品碱的制备方法以及在制备治疗肿瘤药物中的应用,制备方法具有工艺步骤简单、产品纯度高等优点。
目前,国内外学者对中药红毛七的生物活性研究主要是提取物,对其所含化学成分的具体药理活性研究较少,多与其他药材配伍使用,成分复杂,其作用机制尚不明确,尚未见有关红毛七三萜皂苷成分抗糖尿病的相关文献,且其三萜的结构具有较强的特异性,因此,从分离鉴定其中的单体化合物入手,找到其发挥各药效的有效成分,以便进行深入的研究与开发利用,是具有十分重要意义的。

为检测新化合物对蛋白酪氨酸磷酸酯酶1B(PTP1B)的抑制活性,现做以下酶活实验:
PTP1B酶活实验的实验原理为:在PTP1B催化下,底物para-NitrophenylPhosphate(pNPP)水解生成对硝基苯酚。对硝基苯酚在405nm有吸收峰。在405nm下,用酶标仪检测对硝基苯酚的吸光度OD值,吸光度值越高,说明酶的活性越强。当加入抑制剂后,抑制剂阻碍底物(pNPP)与PTP1B的结合,使底物不能水解生成对硝基苯酚,导致吸收值减小。
步骤1、柠檬酸盐缓冲液的配制:称取1.0507g一水合柠檬酸,加水溶解,定容至50mL,得到浓度为0.1mol/L柠檬酸;称取2.941g二水合柠檬酸三钠,加水溶解,定容至100mL,得到浓度为0.1mol/L柠檬酸三钠;取5mL 0.1mol/L柠檬酸和45mL 0.1mol/L柠檬酸三钠混匀,定容至100mL,再加入0.584g NaCl、0.01542g DTT、0.02922g EDTA,待溶解后,用pH计测混合后溶液的pH值,若pH低于6.0,加入适量柠檬酸三钠调节pH至6.0。

步骤4、药物(新化合物和阳性药)的配制:
新化合物溶液的配制:称取0.00664g实施例1步骤(4)所得新化合物,溶解于0.5mLDMSO,得浓度为30mmol/L母液。
阳性药(齐墩果酸)溶液的配制:称取0.00456g Oleanolic acid(齐墩果酸),溶解于0.5mLDMSO,得浓度为20mmol/L母液。
步骤5、NaOH溶液的配制:称取4g NaOH溶于10mL柠檬酸盐缓冲溶液中,浓度为10mol/L。
步骤6、将实验分为模型组(不加药物,加酶、柠檬酸盐缓冲液和底物)、实验组(新化合物)、对照组、空白组和药物组,其中对照组为齐墩果酸(Oleanolic acid),不同组的药物均设置有5个浓度梯度(100μmol/L、30μmol/L、10μmol/L、3μmol/L、1μmol/L),以上每组均设有3个复孔,见表2;

表4新化合物对PTP1B和α-葡萄糖苷酶的抑制活性
其中,IC50(μmol/L)为酶活性抑制率为50%时新化合物的浓度,用于表示对PTP1B或α-葡萄糖苷酶的抑制活性;齐墩果酸和阿卡波糖分别为PTP1B和α-葡萄糖苷酶的阳性对照药。
如表4所示,新化合物对PTP1B和α-葡萄糖苷酶均具有较好的抑制活性。
为更好理解新化合物与PTP1B及α-葡萄糖苷酶的结合模式,现采用分子对接方法进行验证和阐释:
步骤1、数据库有UniProt数据库(https://www.uniprot.org/)、PDB数据库(http://www.rcsb.org/);软件有ChemOffice2010(美国PerkinElmer公司)、SYBYL 1.0软件(美国Tripos公司)、Discovery Studio 2017 R2 Client(DS,美国Accelrys公司开发)、PyMOL。
步骤2、运用ChemDraw软件画出新化合物的结构式,保存为mol2格式。将新化合物的mol2格式结构式导入SYBYL 1.0软件,采用分子力学程序Minimize进行结构优化,赋予Tripos力场及加载Gasteiger-Huckel电荷,优化后得到的稳定构象保存为mol2格式,建立配体小分子化合物库,为分子对接做准备。
步骤3、从PDB数据库(http://www.rcsb.org)下载目标靶蛋白酪氨酸磷酸酯酶1B(PDB ID:1NNY)和α-葡萄糖苷酶(PDB ID:3TOP)的晶体结构,对靶蛋白用Application中的Docking模块进行修饰、加氢及加载AMBER FF99电荷,并根据靶蛋白复合物中配体确定对接的活性位点,将处理后的蛋白保存,为后续分子对接研究做准备。
步骤4、利用SYBYL 1.0软件Surflex-dock模块将配体小分子化合物库和靶蛋白进行分子对接,对接的结果以打分函数Total Score给出,以mol2格式保存。利用SYBYL分子对接模块的Total Score打分函数对配体分子进行筛选,Total Score打分函数综合考虑了极性作用、疏水作用、焓和溶剂化等因素,该值越大,对接复合物越稳定,说明小分子化合物与大分子蛋白质的匹配结合作用越好。
步骤5、采用Discovery Studio软件中receptor-Ligand Interactions模块对分子对接结果进行分析,并制作三维和二维效果图。
表5新化合物与靶蛋白的对接得分
PTP1B蛋白含有435个氨基酸残基,其活性位点包括P-loop,由(His214-Arg221)8个氨基酸残基构成,其中的Cys215是催化中心,另外在活性位点(第一结合位点)的边缘四周有Tyr46、Arg47、Asp48、Val49和Lys120等氨基酸残基,参与酪氨酸底物的识别与结合;WPD-loop由氨基酸残基179-187构成;第二结合位点由Arg24、Arg254、Met258、Gly259和Gln262等氨基酸残基构成。通过对新化合物与PTP1B的结合模式进行研究(图8),化合物稳定占据PTP1B相同的活性口袋,与PTP1B的相互作用力主要是疏水作用和氢键作用。新化合物中23位OH与Asp181、Arg221形成氢键,16位羰基与Ala217形成氢键,3位OH与Gly183形成氢键,六元环、甲基与氨基酸Tyr46、Ala217形成疏水作用力。因此,结合新化合物与PTP1B相似的对接得分(表5),说明新化合物与靶蛋白具有较好的结合活性,新化合物可能是PTP1B的催化位点抑制剂。
通过对新化合物与α-葡萄糖苷酶的结合模式进行研究(图9),化合物稳定占据α-葡萄糖苷酶相同的活性口袋,与α-葡萄糖苷酶的相互作用力主要是疏水作用和氢键作用。新化合物的16位C=O与氨基酸Arg1510形成氢键,六元环、甲基与氨基酸Pro1159、Tyr1251、Ile1280、Trp1355、Trp1369、Met1421、Phe1427、Phe1559、Phe1560形成疏水作用力。相关文献报道,氨基酸Trp1355、Asp1420、Asp1510、Asp1526、Pro1159、Phe1560是α-葡萄糖苷酶活性位点的关键氨基酸,因此,由表5中新化合物与靶蛋白的对接得分可知,新化合物与靶蛋白具有较好的结合活性,本发明的新化合物可能是α-葡萄糖苷酶的潜在抑制剂。
