Description
技术领域
本发明涉及生物医药领域,更具体而言,本发明涉及2,5-二氨甲基吡嗪类化合物、其药物组合物、制备方法和用途。该类化合物可作为抑制剂用于抑制HIV整合酶与LEDGF/p75间的蛋白-蛋白相互作用及HIV整合酶的二聚化,并进而制备用于治疗艾滋病的药物,用于艾滋病治疗。
背景技术
晶状体上皮源性生长因子(lens epithelium derived growth factor,LEDGF)属肝癌衍生生长因子(hepatoma-derived growth factor,HDGF)相关蛋白(HRP)家族,将它加入晶状上皮细胞、成纤维细胞、角质化细胞的培养基中,可促进细胞生长,延长细胞寿命(Poeschla E M.Integrase,LEDGF/p75and HIV replication.Cell Mol Life Sci,2008,65:1403-1424.)。LEDGF与已发现的转录协同激活因子p75为同一种蛋白,因此称为LEDGF/p75。但它既不是一种生长因子,也不是特异在晶状上皮细胞中表达,而是广泛存在于人体各种细胞中。LEDGF/p75在特异性皮炎、哮喘、间质性膀胱炎等多种炎症发生时作为一种核自身抗原,导致自身免疫反应,诱导细胞程序性死亡,与一些自身免疫性疾病相关(Ganapathy V,Casiano C A.Autoimmunity to the nuclear autoantigen DFS70(LEDGF):what exactly are the auto-antibodies trying to tell us?Arthritis Rheum,2004,50:684-688.)。早期研究还表明LEDGF/p75为转录辅助因子PC4的相互作用蛋白,后来发现它可通过激活应激蛋白和抗细胞凋亡蛋白(如热休克蛋白27/90、抗氧化蛋白2)的表达,保护细胞免于压力应激条件诱导的细胞死亡(Shinohara T,Singh D P,Fatma N.LEDGF,a survival factor,activates stress-related genes.Prog Retin Eye Res,2002,21:341-358.)。因此,LEDGF/p75对细胞存活与凋亡起着重要调节作用。
LEDGF/p75在免疫共沉淀过表达整合酶的细胞核提取物中被发现,引起人们极大关注。进一步研究发现,LEDGF/p75将整合酶链合到DNA/染色体上,促进链转移和整合的完成,是HIV-1整合过程中第1个被发现的细胞辅助因子。
LEDGF/p75属肝癌衍生生长因子(HDGF)相关蛋白(HRP)家族,现已发现6个HRP家族成员:HDGF、HRP1、HRP2、HRP3、LEDGF/p75和LEDGF/p52。在基因结构上,HRP家族N端都含有1个PWWP区域,其中LEDGF/p75和HRP2的C端都有1个进化保守序列可与HIV-1整合酶结合,称为整合酶结合域(integrase-binding domain,IBD)。 LEDGF/p75由530个氨基酸残基组成,根据其功能可以划分为2个区域,N端DNA/染色体结合区和C端整合酶结合区。
将可编码荧光蛋白和打靶LEDGF/p75基因的shRNA慢病毒载体转导进入CD4+细胞,强化RNA干扰基因抑制,使CD4+细胞感染HIV-1水平下降10~30倍(Llano M,Saenz D T,Meehan A,et al.An essential role for LEDGF/p75in HIV integration.Science,2006,314:461-464.);CD4+细胞中过表达绿色荧光蛋白-整合酶结合域(IBD)的融合蛋白与LEDGF/p75竞争结合整合酶,使HIV-1感染水平下降7倍,且传代病毒中出现整合酶CDD区域突变的耐受毒株(HombrouckA,De Rijck J,Hendrix J,et al.Virus evolution reveals an exclusive role for LEDGF/p75in chromosomal tethering of HIV.PLoS Pathog,2007,3:418-430.);不能与LEDGF/p75结合的整合酶Q168突变病毒株则无法完成复制(Emiliani S,Mousnier A,Busschots K,et al.Integrase mutants defective for interaction with LEDGF/p75are impaired in chromosome tethering and HIV-1replication.J Biol Chem,2005,280:25517-25523.)。这些研究充分证明了LEDGF/p75是HIV-1的复制和感染必需的细胞辅助因子。LEDGF/p75在HIV整合过程中发挥多种作用,在其他慢病毒中类似(Busschots K,Vercammen J,Emiliani S,et al.The interaction of LEDGF/p75with integrase is lentivirus-specific and promotes DNA binding.J Biol Chem,2005,280:17841-17847.)。LEDGF/p75蛋白-整合酶相互作用使整合酶免于遍在蛋白化作用(ubiquitination)及体内蛋白酶体的降解(Llano M,Delgado S,Vanegas M,et al.LEDGF/p75prevents proteasomal degradation of HIV-1integrase.J Biol Chem,2004,279:55570-55577.)。LEDGF/p75在整合酶的核转运过程中也发挥一定作用。更重要的是,LEDGF/p75利于整合酶与核染色质的相互作用,促进病毒整合过程的进行。在体外试验中,该辅助因子不但激发整合酶的链转移活性,而且可使整合酶与DNA的结合力提高30多倍(Busschots K,Vercammen J,Emiliani S,et al.The interaction of LEDGF/p75with integrase is lentivirus-specific and promotes DNA binding.J Biol Chem,2005,280:17841-17847.)。所以,LEDGF/p75是HIV-1复制必需的细胞辅助因子。
异种蛋白进入细胞后会立即被泛素标记,然后由蛋白酶体降解,而LEDGF/p75可与整合酶相结合而防止整合酶水解,提高其稳定性(Llano M,Delgado S,Vanegas M,et alLEDGF/p75prevents proteasomal degradation of HIV-1integrase.J Biol Chem,2004,279:55570-55577.)。在p75缺陷的细胞系中整合酶mRNA的水平正常,但检测不到整合酶。在这些细胞系中恢复表达p75,整合酶的细胞浓度相应恢复正常,或者过表达绿色荧光蛋 白-整合酶结合域(IBD)的融合蛋白也能使整合酶水平恢复正常。
Bushman实验室对人类基因组大量的HIV整合位点进行了统计学分析,结果发现富含AT的活性转录单位(transcription units,TUs)是HIV-1整合优先发生区域,这与LEDGF/p75的AT-钩基序对富含AT的DNA序列的特殊亲和力一致( ARW,ShinnP,Chen H,et al.HIV-1integration in the human genome favors active genes and local hotspots.Cell,2002,110:521-529.)。现在普遍认为某些细胞因子将整合酶链接到特定的DNA整合位点上,使病毒DNA优先整合到这些特定的序列上,导致出现了某些整合高频的基因座(locus)。这种由宿主决定整合位点的现象在整合机制中常见,例如,与逆转录病毒类似的酵母转座子Ty3通过与转录因子TFIIIB或TFIIIC相互作用,而整合到聚合酶Ⅲ转录起始位点附近的一两个核苷酸处(Kirchner J,Connolly CM,Sandmeyer SB.Requirement of RNA-polymerase III transcription factors for in vitro positionspecific integration of a retrovirus-like element.Science,1995,267:1488-1491.),酵母转座子Ty5通过与Sir4p C端部分结合而整合到端粒的异染色质DNA或不发生交配型转换的沉默暗盒序列(Zhu Y,Dai J,Fuerst PG,et al.Controlling integration specificity of yeast retrotransposon.Proc Natl Acad Sci USA,2003,100:5891-5895.)。与酵母转座子的整合机制类似,整合酶可与LEDGF/p75结合的慢病毒亚科在整合时对TUs序列表现出高度选择性,如人免疫缺陷病毒(HIV)、猴免疫缺陷病毒(SIV)、猫免疫缺陷病毒(FIV)。而不能与LEDGF/p75结合的逆转录病毒(如莫洛尼鼠白血病病毒(MLV))对TUs序列仅有一般选择性,而对启动序列和CpG岛具有高度选择性;猴泡沫病毒(SFV)也对启动序列与富含GC的CpG岛(CpG island)有较高选择性;鸟肉瘤白细胞病毒(ASLV)对整合位点无特殊选择性(Maele B,Busschots K,Vandekerckhove L,et al.Cellular co-factors of HIV-1integration.Trends BiochemSci,2006,31:98-105.Mitchell RS,Beitzel BF,Schroder ARW,et al.Retroviral DNA integration:ASLV,HIV,and MLV show distinct target site preferences.PLoS Biol,2004,2:1127-1137.)。另外,敲除LEDGF/p75基因使HIV病毒整合受阻而影响复制,残余的少量的整合对TUs的选择性大大下降,而对CpG岛和启动序列的选择性提高,这与其他不能结合LEDGF/p75的逆转录病毒整合位点的选择性相似(Shun MC,Raghavendra NK,VandegraaffN.LEDGF/p75functions downstream from preintegration complex formation to effect gene-specific HIV-1integration.Genes Dev,2007,21:1767-1778.Marshall HM,Ronen K,Berry C,et al.Role of PSIP1/LEDGF/p75 in lentiviral infectivity and integration targeting.PLoS One,2007,2:1-13.)。大量试验证明整合酶通过LEDGF/p75链接到DNA特异的序列(TUs)上进行整合, 导致了HIV整合序列的选择性,这方面的研究为其链合机制提供了有力的证据。
HIV的整合酶可催化3′加工和链转移两个过程,整合酶的二聚体将HIV-1cDNA的U3、U5末端分别去掉1个3′-GT二核苷酸,形成可与染色体DNA相匹配的交错切口。然后连接在cDNA两端的两个整合酶二聚体齐聚化形成整合酶四聚体,相关病毒和宿主因子进入形成整合前复合物(pre-integration complex,PIC),该反应在胞浆中发生。整合前复合物进入细胞核,并在整合酶的催化下完成链转移。在体内,整合酶的二聚体可以将HIV-1cDNA的一端整合到宿主DNA,称为半整合(half-site integration);而整合酶四聚体可将HIV-1cDNA的两端都整合到宿主DNA,称为全整合(full-site integration)。Raghavendra观察到LEDGF/p75促进HIV cDNA的半整合而抑制全整合,并通过试验证明了LEDGF/p75可能干扰整合酶的多聚化,但不影响整合前复合物的催化活性。因此推测,LEDGF/p75在整合酶四聚体和整合前复合物形成之后发挥作用,支持了LEDGF/p75结合到DNA/染色体上作为一种链合因子的观点(Raghavendra NK,Engelman A.LEDGF/p75 interferes with the formation of synaptic nucleoprotein complexes that catalyze full-site HIV-1DNA integration in vitro:implications for the mechanism of viral cDNA integration.Virology,2007,360:1-5.)。
目前高效抗逆转录病毒疗法使用的抗HIV感染药物主要是蛋白酶抑制剂和逆转录酶抑制剂,这两类药物极易产生耐药性和毒性,寻找新作用机制和不易产生耐药性的药物是当今抗艾滋病药物研究的首要任务。LEDGF/p75在体内与HIV-1整合酶相结合,是其整合过程必需的细胞辅助因子,对HIV的复制和感染有重要作用,因此LEDGF/p75在抗HIV治疗策略中成为药物研究的理想靶点。
所以,开发出能够抑制HIV整合酶与LEDGF间的蛋白-蛋白相互作用及HIV整合酶的二聚化并具有潜在药物用途的抑制剂对艾滋病的治疗显得十分重要。

实验实施例
实验实施例1生物学活性的测试
抑制HIV整合酶活性测试:
AlphaScreen整合酶活性检测在Optiplate-384微孔板中进行。将组氨酸标记的整合酶(300nM)和不同浓度的待测化合物(0.1μM,1μM,10μM,100μM)在反应缓冲液(25mM Tris–HCl pH7.4,150mM NaCl,1mM MgCl2,0.01%Tween-20和0.1%牛血清白蛋白)中4℃孵育30min。再加入标记有Flag标签的LEDGF/p75(100nM)4℃孵育1小时。随后加入5μL镍螯合包裹的受体珠和5μL联有Flag抗体的供体珠使得其终浓度为20μg/mL,并将微孔板在30℃条件下孵育1小时,使得蛋白与珠子充分交联。用 Multilabel Reader在AlphaScreen模式下读取信号(用680nm激发,在615nm检测荧光信号)。
LEDGF/p75是HIV整合酶核内主要的辅助因子,抑制其与HIV整合酶的结合是开发抑制HIV药物的重要手段,通过AlphaScreen的方法检测化合物对整合酶与LEDGF/p75结合的影响,来检测化合物对HIV整合酶的抑制作用。
AlphaScreen是基于荧光能量转移(TRF-FRAT)主要检测两分子间的相互作用的方法。镍螯合包裹的受体珠可与组蛋白标签结合,联有Flag抗体的供体珠可与Flag标签结合,当LEDGF/p75与HIV整合酶结合,就会使供体珠子和受体珠子靠近,当激光照射时,就会发生能量转移,即供体的激发光激发受体发出荧光,通过检测受体发射的荧光就能检测 LEDGF/p75与HIV整合酶结合。
抑制HIV整合酶二聚化的活性测试:
整合酶二聚化活性测试采用 方法,在OptiWell384-孔微孔板(购自Perkin Elmer公司)上进行,每孔终体积为25μl。抑制剂和整合酶的母液在测试缓冲液(150mMNaCl,25mM Tris-HCl pH7.3,1mM MgCl2,1mM DTT,0.1%(v/v)Tween-20和0.1%(w/v)0.1%牛血清白蛋白)中都被稀释5倍。首先,5μl抑制剂用移液枪加到384孔板的微孔里,然后加入5μl GST-标记的整合酶和5μl6xHis-标记的整合酶母液,微孔板密闭于4°C孵化3小时,让二聚化过程达到平衡。然后,加入10μL谷胱甘肽包裹的供体磁珠和Ni2+包裹的受体磁珠混合液(购自Perkin Elmer公司)。这样,每一微孔的终体积为25μL,每一种磁珠的终浓度为10μg/mL,每一种整合酶蛋白的浓度为30nM。然后,微孔板于室温下再孵化2小时,用 Multilabel Reader(购自Perkin-Elmer公司)在AlphaScreen模式下读取信号(用680nm激发,在615nm检测荧光信号)。抑制整合酶二聚的化合物将改变磁珠交联的程度和相伴随的输出信号。信号减弱的程度(以抑制率%表示)直接与小分子的抑制活性相关。
MTT法对HCT116p53+/+细胞毒性的测试:
细胞毒性测试是用的MTT(3-(4,5-二甲基噻唑-2)-2,5-二苯基四氮唑溴盐)法。将HCT116p53+/+细胞接种于96孔板并让其附着过夜。然后加入相应的待测化合物并让它们连续作用72小时。接着,将MTT溶液(终浓度0.5mg/ml)加入每个孔板并在37℃孵化4小时。去除上清液后,加入二甲亚砜,读取570纳米处的吸光值。CC50值是用待测化合物杀死细胞的百分比和待测化合物浓度的对数坐标图来确定的。

HIV-1IIIB按Johnson&Byington(1990)所述方法改良进行滴定,简述如下:将HIV-1贮存液在96孔板上作4倍稀释,10个梯度,每梯度6个重复孔,同时设置对照孔6孔。每孔加入C8166细胞50μl,每孔终体积为200μl。37℃,5%CO2培养。第3天补加新鲜RPMI-1640完全培养基100μl,第7天在倒置显微镜下观察每孔中HIV-1诱导的细胞病变效应(Cytopathic Effect,CPE),以每孔是否有合胞体(Syncytium)的形成确定;按Reed&Muench方法计算病毒的TCID50。
五、对HIV-1IIIB致细胞病变(CPE)的抑制实验
将8×105/ml C8166细胞50μl/孔接种到含有100μl/孔梯度倍比稀释药物的96孔细胞培养板上,然后加入50μl的HIV-1IIIB稀释上清,1300TCID50/孔。设3个重复孔。同时设置不含药物的正常细胞对照孔。AZT为阳性药物对照。37℃,5%CO2培养3天,倒置显微镜下(100×)计数合胞体的形成。EC50(50%Effective Concentration)为抑制合胞体形成50%时的药物浓度。
