Description

抗丝状病毒化合物及其应用
技术领域
本发明属于医药领域,具体涉及抗丝状病毒的化合物、药物组合物及其应用。
背景技术
丝状病毒科(Filoviridae)是非分段的单链RNA病毒,其包含马尔堡病毒(Marburgvirus)(MARV)、埃博拉病毒(EBOV)和奎瓦病毒(Ceuvavirus)。迄今已鉴别了5种埃博拉病毒株,并且以其首次出现的地点命名:本迪布焦(BundibugyoMBEBOV)、象牙海岸(EBOV-CdI,也称为Tai森林病毒或TAFV)、雷斯顿Oteston)(EB0V-雷斯顿)、苏丹(SEBOV)和扎伊尔(ZEBOV);扎伊尔、苏丹和本迪布焦病毒株通常参与人的发病和死亡。埃博拉-雷斯顿是不会在人中引起严重疾病的唯一已知的丝状病毒,但是它在猴子中可能是致命的。迄今已鉴别了几种马尔堡病毒株,其中穆索科(Musoke)病毒株具有最尚的致死率。
丝状病毒是极其毒性的,可容易地在人与人之间传播,并且是极其致命的,从而在人和非人灵长类动物中引起严重出血热。丝状病毒感染在人中具有23%至高达90%范围内的致死率。然而,尽管它们具有传播性和致死性,但是没有批准的疗法或预防性疫苗可供使用。虽然一些疫苗被批准用于当前的丝状病毒疫情治疗,但无论是从地域、经济等方面考虑,还是面对可能的大规模全球性疫情爆发,与疫苗类药物相比,小分子药物具有便宜、产量大、性质稳定、易于储存和运输等优点,能克服疫苗类药物生产周期长、活性不稳定等缺点。
因此,鉴于丝状病毒感染的传播性和致死性,临床仍然需要能够有效的抗丝状病毒的小分子药物。

具体实施方式
在整个说明书和所附的权利要求书中,给定的化学式或名称应该涵盖所有的立体异构体和光学异构体及其外消旋体(如果存在这种异构体)。除非另有说明,否则所有手性(对映体和非对映体)和外消旋形式都在本发明的范围内。化合物中也可以存在关于C=C双键、C=N双键、环体系等的许多几何异构体,并且预想所有这些稳定的异构体都在本发明中。描述本发明化合物的顺式和反式(或E-和Z-)几何异构体,并且可以分离为异构体的混合物或单独的异构体。本发明的化合物可以光学活性或外消旋的形式进行分离。光学活性形式可以通过拆分外消旋形式或通过由光学活性起始物质合成来制备。用于制备本发明的化合物及本文制备的中间体的所有方法都认为是本发明的一部分。当制备对映体或非对映体产物时,它们可以通过常规方法例如通过色谱法或分步结晶法进行分离。取决于工艺条件,本发明的最终产物可以游离(中性)或盐的形式得到。这些最终产物的游离形式和盐都在本发明的范围内。如果需要,可以将化合物的一种形式转化为另一种形式。游离碱或酸可转化为盐;盐可以转化为游离化合物或另一种盐;可以将本发明的异构化合物的混合物分离成单独的异构体。本发明的化合物、其游离形式和盐可以多种互变异构形式存在,其中氢原子换位至分子的其它部分,并且分子的原子之间的化学键因此进行重排。应该理解,所有互变异构形式,只要它们可能存在,都包括在本发明之内。
符号“R”和“S”表示一个或多个手性碳原子周围的取代基的构型。异构体描述符“R”和“S”如本文所述用于指示相对于核心分子的一种或多种原子构型,并且意在如文献中所定义地使用(IUPAC Recommendations 1996,Pure and Applied Chemistry,68:2193-2222(1996))。
术语“烷基”是指具有特定范围内的特定碳原子数的支链和直链饱和脂肪族烃基。“C1-6烷基”具有1、2、3、4、5或6个碳原子。烷基基团可以被如本文所述的包括但不限于以下的一个或多个基团取代:任选被取代的烷基、环烷基、烷氧基、氨基、醚、卤化物基团(halide)、羟基、硝基、甲硅烷基、磺基-氧代基或硫醇。当在一个例子中使用“烷基”并且在另个例子中使用诸如“烷基醇”的特定术语时,并不意味着暗示术语“烷基”也不指代诸如“烷基醇”等的特定术语。

生物学活性测试
制备化合物的实验方法
g)化合物1-59根据上文所述方法进行制备。化学合成的原料均购自安耐吉、百灵威、迈瑞尔、Sigma-Aldrich、韶远、毕得医药。无水无氧的反应均使用购买的超干溶剂,并用氩气或氮气做保护。
验证化合物的实验方法:
h)1H NMR与13C NMR(Bruker 500or 400MHz,溶剂为氘代甲醇,氘代氯仿或氘代DMSO);质谱(ESI,Thermofisher LCQ or QE);HPLC(Agilent Prostar 218or 1200)
测试化合物的实验方法:
3.1.细胞培养
i)实验所用的细胞为人肾上皮细胞(239T,ATCC#CRL-1573)和人肺上皮细胞(A549,ATCC#CCL185)。细胞培养基采用高糖DMEM培养液(Cellgro,Manassas,VA,USA),内含10%的胎牛血清(FBS,Sigma,St.Louis,MO,USA)及100μg/mL的链霉素和100units的青霉素(Invitrogen,Carlsbad,CA,USA),上述细胞于5%CO2、37℃培养箱中孵育。
3.2.假病毒粒子感染试验和细胞活力试验
j)根据PEI(polyethylenimine,聚乙烯亚胺)转染试剂说明书分别将编码埃博拉病毒GP或马尔堡病毒GP的质粒与复制缺陷型的HIV载体(pNL4-3.Luc.R-E-)质粒共转染至293T细胞中。转染6小时后,去除旧的培养基,PBS洗涤细胞一次,每孔再加入20mL新鲜的培养基进行换液。培养24小时后收集上清病毒液,经0.45μm滤膜(Nalgene,Rochester,NY,USA)过滤,去除细胞碎片,即获得HIV/EBOV和HIV/MARV假病毒粒子,于4℃条件下保存。
k)感染前24小时,在96孔板中接种低传代的A549细胞(1x105/孔)。将合成的化合物连续稀释3倍后与HIV/MARV或HIV/EBOV伪病毒液或与新鲜培养基混合,每孔接入100uL上述混合液共孵育。细胞培养48小时后,用NeoLite萤火虫荧光素酶报告基因(PerkinElmer,Waltham,MA,USA)测定细胞荧光素酶活性,用CellTiter-Glo试剂盒(Promega,Madison,WI,USA)检测细胞活力。将上述病毒液与细胞共培养或者培养液与细胞共培养作为阴性对照,它们的细胞信号用作数据归一化。用GraphPad逻辑回归法拟合剂量-反应曲线来确定化合物的IC50和CC50值,结果见表1。如表1所示,本发明的发化合物具有良好抗丝状病毒活性和优秀的治疗指数。
