Description
技术领域
本发明涉及生物医药领域,具体涉及用于预防或治疗新冠病毒的多肽、编码其的多核苷酸、包含该多核苷酸的核酸构建体、包含该核酸构建体的表达载体、转化的细胞以及包含上述的药物组合物,以及它们在制备预防和/或治疗新冠病毒的药物或疫苗中的应用。
背景技术
SARS-CoV-2病毒为新冠肺炎疫情的病原体,是21世纪以来引起人类疫情的第三种冠状病毒。目前,虽然已有多种针对SARS-CoV-2的疫苗和单克隆抗体药物获得紧急使用许可,但是多数研究表明它们对当下广泛传播的新冠病毒变异毒株,例如Alpha(B.1.1.7)、Beta(B.1.351)和Gamma(P.1)等,表现出下降的保护效果,因而亟待开发针对目前流行以及未来出现的新的变异毒株的广谱药物或疫苗。
目前已报道有多种新冠相关冠状病毒(属于sarbecovirus),如蝙蝠源RaTG13、RmYN02、ZC45、ZXC21等,穿山甲源GX/P2V/2017和GD/1/2019,研究表明RaTG13、 GX/P2V/2017、GD/1/2019等也存在感染人的潜力,因而也亟需研发针对这些相关冠状病毒的药物或疫苗,以应对将来可能出现的新的疫情。
发明内容
发明目的
本发明的目的在于提供用于预防或治疗新冠病毒的多肽、编码其的多核苷酸、包含该多核苷酸的核酸构建体、包含该核酸构建体的表达载体、转化的细胞以及包含上述的药物组合物,以及它们在制备预防或治疗新冠病毒的药物或疫苗中的应用。
冠状病毒刺突(S)蛋白在介导病毒入侵过程中发挥着重要作用,分为S1和S2两个亚基;其中S1亚基负责识别受体,S2亚基介导病毒囊膜与宿主细胞膜的膜融合。S2中的七肽重复序列HR1和HR2通过形成六螺旋束结构发挥膜融合功能,研究表明加入外源的HR1或HR2多肽能够抑制病毒本身的HR1和HR2六螺旋束结构的形成,进而抑制膜融合过程。本发明的多肽正是基于SARS-CoV-2的S蛋白的HR2区域进行设计的,其能够有效抑制S蛋白介导的膜融合过程,进而抑制新冠病毒的感染。

多肽梯度稀释液的配制:用含10%FBS的DMEM培养基将上述20μM的各多肽原液以2倍的倍比稀释,共稀释9个梯度(分别为10、5、2.5、1.25、0.625、0.3125、0.156、 0.078、0.039μM),每个梯度3个复孔,每孔50μL。
假病毒用量的确定:将SARS-CoV-2原始毒株或变异毒株假病毒原液及一系列稀释液在Hela hACE2细胞上进行定量,将出现1000个FFU时的稀释度作为评价多肽抑制效果时的病毒用量(稀释倍数介于6~20倍之间)。
病毒抑制效果的测定方法为:
a.在96孔细胞培养板中铺Hela hACE2细胞,培养使第二天细胞汇合密度达到 80-90%。
b.根据上述实验分组,取上述各多肽梯度稀释液,加入等体积(50μL)的定量的假病毒稀释液,混匀后,在37℃孵育1h。
c.将步骤a中的96孔细胞培养板上清小心弃去,加入步骤b中的多肽-假病毒混合液 (100μL/孔),在培养箱中继续培养15h-24h。
d.利用高内涵显微镜统计被感染的细胞数,计算各多肽在不同浓度下的抑制率,再利用GraphPad计算出各多肽的IC50(如图2所示),结果见表2;并计算出衍生多肽P3-1~5相较于多肽P3对SARS-CoV-2原始毒株假病毒抑制效果的提升倍数,结果见表3。
表2.多肽对SARS-CoV-2原始毒株及其变异毒株假病毒抑制效果(IC50)
表3.衍生多肽P3-1~5相较于多肽P3对SARS-CoV-2原始毒株假病毒抑制效果的提升倍数
从表2、表3可知,P3多肽对SARS-CoV-2原始毒株及多种变异毒株均具有很好的抑制效果(0.45μM≤IC50≤1.39μM),相比于P3多肽,衍生多肽P3-1、P3-2、P3-3 和P3-4对SARS-CoV-2原始毒株及多种变异毒株的抑制效果均具有不同程度的提升,尤其是多肽P3-3提升最为明显。P3-5的抑制效果虽略有下降,但是其对Kappa变异毒株的抑制效果略高于P3。
从表2、表3可知,本发明的多肽能够用于预防或治疗由新冠病毒引起的疾病,推测也可以广泛用于sarbecovirus引起的疾病。
在SARS-CoV-2入侵宿主细胞的过程中,本发明的多肽通过抑制S蛋白介导的膜融合过程抑制病毒入侵,适用于对新冠病毒原始毒株及变异毒株,例如D614G、 B.1.1.7(Alpha)、B.1.351(Beta)、P.1(Gamma)、Kappa(B.1.617.1)或Delta(B.1.617.2)的治疗或预防,推测对sarbecovirus及未来出现的新的新冠病毒变异毒株也有抑制作用,具有潜在的广泛应用价值。
最后应说明的是:以上实施例仅用以说明本发明的技术方案,而非对其限制;尽管参照前述实施例对本发明进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
