Abstract
本发明涉及一种罗布麻花或/和罗布麻叶的新应用,主要涉及罗布麻花或/和罗布麻叶在制备抗冠状病毒的药物中的应用。与传统技术方案相比,本发明具备如下优势效果:本发明的发明人经过大量的筛选,发现罗布麻叶和罗布麻花均具有较强的抑制冠状病毒感染和抗新冠病毒的功效,将其制备成抗冠状病毒的药物,能为预防或/治疗冠状病毒提供有效手段。
Description
技术领域
本发明属于生物医学领域,涉及一种罗布麻叶或/和罗布麻花的新应用。
背景技术
冠状病毒是一个大型病毒家族,已知可引起感冒、中东呼吸综合征(MERS)和严重急性呼吸综合征(SARS)等较严重疾病。新型冠状病毒是以前从未在人体中发现的冠状病毒新毒株。国际病毒分类委员会将此种新病原体命名为严重急性呼吸综合征冠状病毒2号(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2)。
人感染了新冠病毒(SARS-CoV-2)后常见体征有呼吸道症状、发热、咳嗽、气促和呼吸困难等。在较严重病例中,感染可导致肺炎、严重急性呼吸综合征、肾衰竭,甚至死亡。因此,寻找有效抑制新冠病毒的候选药物是亟待解决的技术问题。
发明内容
基于以上技术问题,本发明的目的之一是提供罗布麻叶或/和罗布麻花的新应用,主要是用于制备抗冠状病毒的药物。
本发明的目的可以通过以下技术方案实现:
罗布麻花或/和罗布麻叶在制备抗冠状病毒的药物中的应用。
在其中一些实施例中,所述的药物包含所述罗布麻花的提取物或/和罗布麻叶的提取物以及药学上可以接受的辅料。
在其中一些实施例中,所述罗布麻花的提取物为罗布麻花的水提物。
在其中一些实施例中,所述罗布麻叶的提取物包含罗布麻叶的水提物或/和罗布麻叶的醇提物。
在其中一些实施例中,所述罗布麻叶的醇提物为乙醇体积百分比为50%-90%的乙醇水溶液的提取物。
在其中一些实施例中,所述辅料包含稀释剂、润湿剂、黏合剂、崩解剂、润滑剂、色香味调节剂、溶剂、增溶剂、助溶剂、乳化剂、抗氧剂、金属络合剂、惰性气体、防腐剂、局部止痛剂、pH调节剂以及等渗或等张调节剂中的至少一种。

罗布麻叶和罗布麻花的抗冠状病毒功效,利用模拟新冠病毒SARS-CoV-2感染的假病毒,以及对新冠病毒外壳(SARS-COV-2)的刺突蛋白(Spike protein)与血管紧张素转化酶2(ACE2)受体结合的抑制作用两个模型,用不同的浓度罗布麻叶和罗布麻花提取物进行测试。
显示罗布麻叶醇提物有很强的抗冠状病毒功效,罗布麻叶和罗布麻花水提物功效次之。
一、罗布麻花和罗布麻叶对SARS-CoV-2 Spike假型病毒的抑制作用
(1)实验原理
假病毒是一类嵌合型病毒颗粒,是在一种复制缺陷型病毒(病毒载体)的表面上表达另一种病毒的重组糖蛋白的嵌合病毒颗粒。用新冠病毒S蛋白替代病毒载体中的包膜糖蛋白,形成模拟新冠病毒SARS-CoV-2感染的假病毒。如果中药提取物能抑制假病毒的入侵和感染,这代表该提取物也能抑制新冠病毒入侵。
(2)实验材料
高糖Dulbecco's Modified Eagle培养基(DMEM)购自Gibco(UK)。胎牛血清(FBS)购自Gibco(巴西)。青霉素和链霉素(Pen/Strep)购自Gibco。胰蛋白酶-EDTA(1x)购自Gibco。萤光素酶检测系统购自Promega。Protein Assay Dye Reagent Concentration购自Bio-Rad。牛血清白蛋白(BSA)购自Sigma。酶标仪购自Thermo Scientific。MicroplateLuminometer购自GLOMAX。
(3)实验步骤
细胞培养:HEK293T细胞在含有10%(v/v)小牛血清(FBS)和1%(w/w)Pen/Strep的高葡萄糖Dullbecco改良Eagle培养基(DMEM)中培养。通过用pcDNA3.1-hACE2质粒转染进行ACE-2过表达的HEK293T细胞系。
SARS-CoV-2假病毒的产生与采集:HEK293T细胞与质粒NR-52514、NR-52516、NR-52517、NR-52518、NR-52519共转染,产生SARS-CoV-2 Spike假型病毒颗粒。转染后48小时收集上清液中的假病毒,用孔径为0.45μm的过滤器过滤并储存在-80℃。
表1、建立SARS-CoV-2 Spike假型病毒模型共转染的质粒类型和作用
质体类型 | 嵌入 | BEI Resources产品编号 |
Viral Entry Protein | Spike Glycoprotein | NR-52514 |
Lentiviral Backbone | Luc2;ZsGreen | NR-52516 |
Helper Plasmid | Gag;pol | NR-52517 |
Helper Plasmid | Tat1b | NR-52518 |
Helper Plasmid | Rev1b | NR-52519 |
假病毒入侵试验:ACE-2过表达的HEK293T细胞已接种在48孔板中,每孔加入100μL假病毒(同时加入检测样品)和400μL培养基,孵育过夜。将培养基换成DMEM、FBS和Pen/Strep的混合物,培养48小时后,用1×PBS洗涤,然后进行荧光素酶活性测定。
以中和抗体(A19215)为阳性对照,溶剂空白和无假病毒组为阴性对照。检测样品为罗布麻花和罗布麻叶的水提取物和醇提物。检测样品最终浓度控制在1μg/mL至100μg/mL。用溶剂空白的荧光素酶活性检测数据标化荧光素酶活性,计算样品抑制病毒的百分比。每个样品加三个孔,取平均值,实验重复三次。
(4)实验结果
在实验中,以中和抗体A19215溶液为阳性对照。结果如图1、图2、图3和图4所示。
如图1和图2所示,罗布麻叶的醇提物(如图1)和罗布麻叶的水提物(如图2)对假病毒的抑制作用呈剂量依赖方式,当浓度为100μg/mL时,罗布麻叶的醇提物对假病毒抑制率高于90%。
如图3所示,罗布麻花的水提物(如图3)和罗布麻叶的水提物对假病毒抑制率都高于80%。
比较罗布麻叶和罗布麻花醇提物和水提物对假病毒的抑制作用(图4),数据显示:罗布麻叶和罗布麻花均表现出显著的抗新冠病毒(SARS-CoV-2)作用。罗布麻花的醇提物对假病毒没有抑制效果,所以未列出数据。
表2
二、检测罗布麻花和罗布麻叶对新冠病毒外壳(SARS-COV-2)的刺突蛋白(Spikeprotein)与血管紧张素转化酶2(ACE2)受体结合的抑制作用
(1)实验原理
通过检测罗布麻样品对新冠病毒外壳(SARS-COV-2)的刺突蛋白(Spike protein)与血管紧张素转化酶2(ACE2)受体结合的抑制作用,来表示中药提取物的抗病毒功效。当刺突蛋白被中药提取物抑制时,其与人类受体——血管紧张素转化酶2(ACE2)的结合就会降低。刺突蛋白与ACE2的结合越少,则罗布麻提取物抑制冠状病毒的功效越强。该方法是目前测试药物抗新冠病毒(SARS-CoV-2)功效的一种有效的体外检测手段。
(2)实验材料
罗布麻花和罗布麻叶提取物稀释至4个不同浓度,利用SARS-CoV-2 Spike:ACE2Inhibitor Screening Assay Kit(购自BPS Bioscience公司)进行抗新冠病毒(SARS-CoV-2)测试。
(3)实验步骤
将浓度为1μg/mL的刺突蛋白溶液加入特制的96孔板中,每孔加50μL,4℃过夜孵育。孵育完成后,倒去上清液,用100μL封闭液A清洗3次。拍干液体,每孔加入100μL封闭液B,室温振荡1小时。拍干液体后,每孔加入20μL封闭液A,阳性对照孔和阴性对照孔中分别加入10μL 5%(v/v)的DMSO水溶液,样品孔加入10μL样品溶液(含有5%DMSO),室温振荡1小时。
阳性对照以中和抗体A19215作为模拟实验最高抑制率的情况,阴性对照孔和样品孔中分别加入20μL浓度为2.5ng/μL的ACE2-His溶液,室温振荡反应1小时。反应完成后拍干液体,用100μL封闭液A清洗3次。拍干液体,每孔加入100μL封闭液B,室温培养10分钟。培养结束后拍干液体,每孔加入10μL Anti-His-HRP溶液,室温振摇培养1小时。先用100μL封闭液A清洗3次,紧接着每孔加入100μL封闭液B,室温培养10分钟。最后,拍干液体,每孔加入100μL ELISA ECL substrate A和B(1:1)的混合液,测定化学荧光强度。
(4)实验结果
在实验中,以中和抗体A19215溶液为阳性对照;以不加任何抑制剂的溶液为阴性对照。结果参见图5、图6、图7和图8。
不同浓度罗布麻叶醇提物结果如图5所示;不同浓度罗布麻叶水提物结果如图6所示;不同浓度罗布麻花水提物结果如图7所示。比较浓度为100mg/L的各提取物抑制新冠病毒作用(图8),罗布麻叶醇提物和罗布麻叶水提物的功用好于和罗布麻花水提物,而10mg/L的提取物中,只有罗布麻叶醇提物有抑制新冠病毒的效果。罗布麻花的醇提物没有抑制效果,所以未列出数据。
表3
表4
综上所述,本发明利用模拟新冠病毒SARS-CoV-2感染的假病毒为模型和对新冠病毒外壳(SARS-COV-2)的刺突蛋白(Spike protein)与血管紧张素转化酶2(ACE2)受体结合的抑制作用两个模型,验证罗布麻花的水提物,以及罗布麻叶的水提物、罗布麻叶的醇提物能够抑制新冠病毒假病毒的入侵,以及减少刺突蛋白与血管紧张素转化酶2的结合,从而可以起到抑制冠状病毒的作用,为冠状病毒感染的控制提供新的解决方案。
