Description
技术领域
本发明涉及可抑制HIV复制的2,4,5-三取代噻唑类化合物,及其它们的制备方法和包含它们的组合药物以及用它们制备抗HIV药物的用途,并包括它们在医疗领域的运用。
背景技术
人类免疫缺陷病毒(human immunodeficiency virus,HIV)是一种RNA病毒,它通过感染人体免疫系统的T淋巴细胞而使得人体免疫系统的功能遭受严重的破坏,导致死亡。由该病毒所导致的疾病称为获得性免疫缺陷综合症(acquiredimmunodeficiency syndrome,AIDS),也称之为艾滋病。
根据联合国艾滋病规划署(UNAIDS)的统计数据,自1981年,在美国发现首例艾滋病至今,已有超过6000万感染了艾滋病病毒,并造成大约2500万人的死亡。联合国艾滋病规划署(UNAIDS)发布的《2011年全球艾滋病流行状况报告》表明,截止到2010年年底,全球艾滋病病毒感染人数共为3400万[3160万-3520万],其中2010年艾滋病新发感染人数为270万[240万-290万],死亡人数为180万[160万-190万]。与2005年相比,2010年艾滋病的死亡人数已经从220万(210万-250万)降低到180万(160万-190万)。自从1995年,在低收入和中等收入国家通过艾滋病治疗已经挽救了大约250万人的生命。截至2011年底,估计我国存活艾滋病病毒感染者和艾滋病病人总数为78万人,其中艾滋病病人15.4万人。2011年当年新增艾滋病病毒4.8万人,2011年艾滋病相关死亡2.8万人。通报还显示,我国的艾滋病疫情持续上升,但上升幅度减小,另外,在局部地区和特定人群中疫情严重,所以对于艾滋病的防治工作依旧需要深入开展。
目前发现的HIV主要分为两种类型:HIV-1和HIV-2型,在世界范围内流行的主要是HIV-1型,而HIV-2型主要是流行于非洲西部地区,目前研发的药物主要是针对HIV-1型。由于缺乏有效的HIV疫苗和HIV高度的变异性,所以研究开发出高效抗HIV的药物仍是目前对抗艾滋病的工作重点。截止2011年,已有26种药物获得批准上市用于治疗艾滋病(主要针对HIV-1型),按照这些药物的作用机制可以将它们分为五类:逆转录酶抑制剂、蛋白酶抑制剂、融合抑制剂、整合酶抑制剂和进入抑制剂,其中可将逆转录酶抑制剂继续细分为核苷(酸)类逆转录酶抑制剂和非核苷类逆转录酶抑制剂(Bingjie Qin,Xingkai Jiang,Hong Lu,et al.J.Med.Chem.2010,53,4906–4916)。临床上使用这些药物,通过高效抗逆转录疗法(highly active antiretroviraltherapy,HAART,俗称“鸡尾酒”疗法),有效地降低了HIV-1感染者的发病率和死亡率,使病人的生命得以延长。但是由于这些药物不能完全将病人体内的病毒去除,病毒仍然在病人体内低水平复制,一旦停药,病毒很快就会恢复到或超过用药前的水平。另外,随着越来越多的耐药性HIV变异株的出现,HAART对一些病人的疗效已经大打折扣。所有的这些问题都是对艾滋病治疗的极大挑战,因此研究开发出能彻底清除病毒或高效抑制病毒复制的新药一直都是人们研究的热点。
HIV-1逆转录酶是由P66和P51两个亚基组成的异二聚体酶,在p66的N端是该酶的结构域,其外形结构和人的右手相似,可细分为手指、手掌、拇指和链接域等4个亚结构域,酶的催化活性中心就处于p66的手掌区域,在与该催化活性中心相邻的地方有一个可变构的疏水性非核苷类抑制剂结合口袋(nonnucleoside inhibitor-biding pocket,NNIBP)(Das,Kalyan;Lewi,Paul J.;Hughes,Stephen H.;Arnold,Eddy.Prog Biophys Mol Biol,2005,88:209-231),其就是非核苷类逆转录酶抑制剂的作用位点。HIV-1逆转录酶是病毒复制周期中至关重要的一种酶,其具有以RNA为模板的DNA聚合酶活性(催化合成负链DNA)、核糖核酸酶H(RNase H)活性(水解引物tRNA和DNA-RNA双链体中的基因组RNA)和以DNA为模板的DNA聚合酶活性(催化合成正链DNA),它的催化作用是以原病毒RNA为模板逆转录合成出双链的病毒DNA(合成的病毒DNA通过整合酶的作用整合进入宿主细胞的染色体中)(Sarafianos Stefan G.;Marchand Bruno;Das Kalyan;et al.J.Mol.Biol.2009,385(3),693-713;De Clercq Erik Nat.Rev.Drug.Discov.2007,6(12),1001-1019)。正是因为逆转录酶在病毒复制周期中的不可缺性使得它一直以来都备受关注,许多研究者都以其为靶点,设计合成出一系列逆转录酶抑制剂。在目前上市的逆转录酶抑制剂中有8个为核苷(酸)类抑制剂和5个为非核苷类抑制剂,后者分别是奈韦拉平、地拉夫定、依法韦仑、依曲韦林和利匹韦林。
非核苷类逆转录酶抑制剂是高效抗逆转录病毒治疗中的一类重要药物,通常与核苷类逆转录酶抑制剂及蛋白酶抑制剂共同应用。随着高效抗逆转录病毒治疗的长期广泛使用,HIV出现稳定的耐药性变异并传播,导致治疗失败。据统计,临床至少有50%患者体内至少存在一种耐药突变病毒。非核苷类逆转录酶抑制剂奈韦拉平、地拉夫定、依法韦仑已经应用于临床十余年,已出现了稳定的耐药突变病毒,据2010年数据显示,前8种耐药突变发生率超过20%(http://hivdb.stanford.edu/pages/phenoSummary/Pheno.NNRTI.Simple.html),且具有多药耐药的特点。因此,研发新型非核苷类逆转录酶抑制剂仍然是抗艾滋病药物研发的重点。

实施例93药理实验
1.重组病毒筛选模型的原理:
本模型应用了VSVG/HIV重组病毒技术,将表达HIV-1(pNL4-3,可为野生株或含突变位点的耐药株)核心和VSV-G(水泡性口膜炎病毒糖蛋白)的质粒共转染后生成了以VSV-G外壳包裹HIV-1核心的VSVG/HIV病毒颗粒。由于水泡性口膜炎病毒(VSV)的受体广泛存在,因而当用它的外壳糖蛋白VSV-G包裹HIV-1核心,可高效率地将HIV-1核心导入宿主细胞,然后按照HIV-1的方式进行复制。该重组病毒的特点是:HIV-1的基因组中敲除了env、vpr和nef基因,因此使得病毒颗粒仅能单次感染细胞并在感染的细胞内复制,不能再次进行包装和繁殖,因此可以在常规的实验室进行操作;在nef基因的位置引入了报告基因(荧光素酶基因),因此测定报告基因的表达水平(即荧光素酶的活性)可以反映HIV-1的复制水平,该重组病毒检测系统可以作为安全的HIV-1复制抑制剂的筛选模型。同时,我们用流感病毒血凝素蛋白(HA)包裹HIV-1核心,构建HA/HIV重组病毒作为对照,使用VSVG/HIV-1及HA/HIV-1相结合的方法测定化合物的活性,可以排除非HIV-1复制以外因素的干扰。
2.实验方法:
感染前一天,将293T细胞按每孔6×104的密度接种到24孔板上。用DMSO溶解阳性对照化合物(奈拉韦平和依法韦仑)或本发明实施例化合物(母液浓度为10mmol/L,并以此为基础用DMSO稀释)。感染前15分钟将待测化合物/阳性对照化合物加入细胞培养液中(DMSO终浓度为0.1%),以DMSO溶剂作空白对照。再加入0.5ml病毒液(病毒液的滴度为0.3ng p24/ml)。感染后48小时,去除上清,每孔中加入50μl细胞裂解液(Promega)裂解细胞,再将20μl细胞裂解产物加入至30μl荧光素酶底物中(Promega),用FB15荧光检测器(Sirius)仪器测定细胞荧光素酶的相对活性,其活性的强弱反映了HIV-1复制的水平,以DMSO作对照,结果见表1。
