Abstract
本发明提供了含阴离子化合物的三嗪环,含这些化合物的药物组合物以及利用这些化合物治疗病毒感染特别是呼吸道融合病毒感染的方法,所述化合物具有下列结构:
Description
本发明涉及含阴离子化合物的新三嗪环,所述三嗪环用于治疗病毒感染,特别是人呼吸道融合病毒〔HRSV〕。本发明还涉及治疗病毒感染的方法及其药物组合物。
人呼吸道融合病毒〔HRSV〕首先发现于1965年并于全世界广泛分布。这是在婴儿和少年儿童中导致上下呼吸道疾病的重要原因,在美国每年引起大约100,000人住院并有5,000人死亡(Chanock,R.M.,Kim,H.K.,Brandt,c.D.,and Parrott,R.H.1982.Respi ratory syncytial virus,pp 471-489,inViral Infections of Humans,Second Edition,A.S.Evans,editor(PlenumPress,NY).Glezen,W.P.,Taber,L.H.,Frank,A.L.,and Kasel,J.A.,1986.Risk of primary infection and reinfection with respi ratorysyncytial virts.Am.J.Dis.Chil.140;543-546.MacDonald,N.E.,Hall,C.B.,Suffin,S.C.,Alexson,C.,Harris,P.J.,and Manning J.A.1982.Respi ratory syncytial virus infection in infants with congential heartdisease.New England Journal of Medicine 307;397-400)。
在急性呼吸道疾病住院少年儿童中,大约由30%的人具有呼吸道融合病毒感染。在年龄大的儿童和成年人中,疾病程度轻一些。在上了年纪的人中,HRSV似乎也是发病和死亡的主要原因(相当于流感)(Fleming,D.M.and Cross,K.W.1993.Respiratory syncytial virus or influenza?Lancet 342;1507-1510.)。具有呼吸道融合病毒的感染是指呼吸道的所有部分,且通常与发烧、咳嗽、流涕和疲劳有关,临床诊断为支气管炎、细支气管炎、肺炎、格鲁布或病毒感染。在年龄大的儿童和成年人中,病毒一般仅限于在上呼吸道中复制,而当病毒延伸至肺时,婴儿的发病可能会更严重,而且对肺的损伤可能是永久的。
呼吸道融合病毒的主要感染是发生在生命的早期,通常是在4岁之前。在儿童中,由这种病毒引起的疾病至少一年发作一次,而在相当严重时可几个月发作一次。流行性是非常局限的,通常为3至5个月。在家庭研究中,低年级的儿童经常将病毒带人家里,对家庭中年轻成员的影响要比其他成员更严重。在第一次感染的临床结果最严重,然而,对于具有免疫经历的年龄大的个体来说,其临床结果会变得轻一些。
呼吸道融合病毒的影响结果可从不明显感染到严重的肺炎和死亡。呼吸道炎症是最常见的症状。在多数情况下的完全康复发生在1至3周后,产生了似乎在生命中永久存在的抗体。在美国,大约30%的1岁婴儿和95%的5岁儿童具有呼吸道融合病毒循环抗体。具有抗体的年龄大的婴儿、儿童和成年人的再感染多数是感冒形式的轻微上乎吸道疾病。在婴儿和少年儿童中利用广谱抗病毒剂ribavirin进行治疗,但是使用这种化合物受到了毒性约束。因此非常需要一种新的处理HRSV感染的治疗剂。
美国专利5,359,131指明了一种磺酸均二苯乙烯,它通过疱疹复合病毒(HSV)、人免疫缺陷病毒(HIV)和巨细胞病毒(CMV)阻滞细胞的感染。
本发明涉及一种新的含阴离子化合物的三嗪环,该三嗪环显示出抗病毒活性,特别是抗人呼吸道融合病毒的活性,
本发明涉及选自通式Ⅰ的新化合物及其可药用盐和酯:
式Ⅰ其中:
B’为-NH、-NR1或0;
R1为选自H、(C1-C6)直链或支链低级烷基,其中碳原子可由Cl、Br、F、OH或CN任意地取代;
X为Cl、F或下式部分
U’为选自-SO2、-CO、-NC(O)或-NC(S);
W’选自下述基团:
Y为-(CH2)n-;
n为0至6;
m为0至2;
在各种情况下,R2为独立地选自H或(C1-C6)低级烷基。
可以理解,当m为0时,W’应当指5-元环。
本发明化合物的可药用盐是那些其中的阳离子在达到所需效果的给药剂量时基本无毒且本身不具有明显药物活性的可药用盐。例如,这些盐可包括碱金属盐如Na或K盐,碱土金属盐如Ca或Mg盐,包含Al的Ⅲa族的轻金属盐以及有机伯,仲和叔胺或铵。钠盐为优选。
在特别优选的化合物中,
C’=-SOH,B’=-NH,Y=-CH2-,Z=-CH2OH在最优选的化合物中,
C’=-SO3H,B’=-NH,Y=-CH2CH2-,Z=-CONH2在更优选的化合物中,A为且C’=-SO3H,B’=-NH,Y=-CH2CH2-,Z=-CONH2。
本发明的新化合物可根据下述流程制备。对于流程Ⅰ,在大约0℃且pH为大约6.5-大约7.2下,综合其中A和B’如上文定义的2与其中X为Cl、F或Br的结构3的三嗪,可得到中间体4。在温度为大约45℃至大约55℃且pH为6.5-7.2下,式4化合物与其中U’、B’和W’如上文定义的式5化合物进一步反应,接着在100℃-120℃、pH为6.5-7.2下加热得到所需的上述式Ⅰ产物,该产物在流程图中以1表示。
P3-P4流程图Ⅰ
在如流程Ⅱ所示的式Ⅰ化合物另-合成路线中,在大约-5℃至大约5℃且pH为6.5-7.2下,其中X为Cl、Br或F的三嗪3与其中B’和W’如上文定义的化合物5反应,得到缩合产物6。在大约45℃至大约55℃且pH为大约6.5-大约7.2下,其中B’和W’如上文定义且X为Cl、Br或F的6与A和B’如上文定义的2反应,接着在大约100℃至大约120℃且pH为6.5-7.2下加热得到1。
如流程Ⅰ所示的起始化合物2以及如流程Ⅱ所示的5与其中X为Cl、Br或F的三嗪3的分步缩合反应是类似地在适当碱如氢氧化钠、氢氧化钾、碳酸盐、磷酸盐或碳酸氢盐存在下,在含水介质或有机溶剂-水介质中进行的。pH为7的磷酸盐缓冲液为优选。
第一缩合步骤是在pH范围为大约4至大约8,优选大约6.5至大约7.2,温度为大约-10℃至大约30℃,优选大约-5℃至5℃下进行的。三嗪衍生物的第二卤原子的交换是在相同pH范围和大约10℃至大约70℃,优选大约45℃至大约55℃下进行的。三嗪衍生物的第三卤原子的交换是在相同pH范围和大约80℃至大约150℃,优选大约100℃至大约120℃下进行的。

用于流程Ⅰ和Ⅱ所示的一般合成步骤的起始原料可从商业途径得到或根据下述文献合成:H.Adkins,E.F.Steinbring,E.Pickering.J.Amer.Chem.Soc.,v.46,p.1917(1924),英国专利1,194,388(1970年6月10日)和美国专利5,359,131(1994年10月25日)。其中B’为氧的式2起始化合物可通过流程Ⅲ所示的取代式2(B’=-NH2)化合物制得。
对于流程Ⅳ,通过催化还原条件(氢-Pd/C)或现有技术中公知的将取代均二苯乙烯化合物转变成二苄基化合物的相关还原条件[Huang-Minlon,J.Amer.Chem.Soc.(1948)70,2802],可将均二苯乙烯系列化合物(10)转变成二苄基系列化合物(11)。

在预处理的原始记录中,利用不同浓度的化合物处理6孔平板中的融合细胞1小时。加入小体积的病毒(~100pfu),培养(RSV、CMV和HPIV3(3型人的类流感病毒,Washington系),5-8天;流感和疱疹复合病毒,225天)后计数蚀斑。对于后处理,细胞首先感染1小时且替代介质(含未吸收的病毒)。在感染后2小时或24小时加入含不同浓度化合物的介质。所使用的细胞包括vero(非洲绿猴细胞)、HF(人包皮纤维细胞)、SKNSH(人成神经细胞瘤细胞)、MDBK(Madin-Darby牛肾细胞)和MDCK(Madin-Darby犬肾细胞)。作用机理
为了增强理解作用机理,要确定使用实施例1化合物对病毒生命循环周期起作用的时间,这是通过在相对于感染的不同时间加入或除去化合物并测定其对病毒蛋白合成的影响而完成的。将vero细胞在冰上感染1小时,除去未吸附的病毒,然后将感染的细胞在37℃下培养18小时(在冰上将发生病毒吸附,但是不进行融合,直至温度升至18℃或以上)。在37℃下培养18小时以后(当所进行的蛋白合成是由病毒RNAs指导之时)加入35S-蛋氯酸2小时,溶解细胞,在SDS-PAGE胶上分析标记蛋白质。病毒N、P和M将非常明显。如果在病毒吸附之后目在培养温度升至37℃之前立即加入10μg/ml实施例1化合物,病毒蛋白合成将被完全预防。然而,当在37℃下培养甚至仅5分钟之后加入实施例1化合物时,病毒蛋白合成也不会被预防。因此,抑制过程为融合过程,或者是某种后来病毒基因表达所需的非常接近的后续步骤。
众所周知,紧密接触的RSV感染细胞将融合成融合病毒,而且此过程仅取决于病毒F、SH和G蛋白(Heminway BR,Yu Y,Tanaka Y,Perrine KG,Gustafson E,Bernstein JM,Galinski MS.1994.Analysi s of respi ratorysyncytial virus F.G and SH proteins in cell fusion.Virology 200;801-805)。融合形成不应涉及病毒的功能如脱壳或转录,它们通常是在融合形成之后并且是后来的病毒的基因表达所需的。
为了确定本发明化合物是否抑制融合或进行后面的步骤,用它们来试验在预先由RSV感染的细胞中预防融合形成的能力。在1小时内,将vero细胞重复感染3次,然后用新鲜介质替代原始介质。培养6小时后,加入化合物。在24小时和48小时后,在显微镜下检测感染的细胞,从而确定融合形成的程度,将很容易地识别由于存在化合物的融合形成差异,并且根据此试验很容易地划分化合物效力等级。由此方法判断的IC50与实际IC50是近似的,对于化合物16和17,其值分别为0.3和0.05μg/ml。这些化合物抑制融合形成的能力表明它们在病毒生命循环周期的融合步骤中是起作用的。实施例1和4的化合物防止体内RSV生长
被RSV感染接着通过小颗粒气溶胶(SPA)给药后的棉鼠(cotton rat)被用于测定化合物的体内抗-RSV的效力。(Gilbert BE,Wyde PR,Wilson SZand Meyerson LR.1993.SP-303 small particle aerosol treatment ofinfluenza A virus infection in mice and respiratory syncytial virusinfection in cotton rats.Antivi ral Research 21;37-45.)
在这样的系统中试验本发明化合物,从而确定其是否能够抑制棉鼠中的RSV生长.在实验1(见表3)中,动物通过鼻内感染RSV A2(第0天),导致呼吸道感染.在气溶胶室中使用于水中的60mg/ml Rabavirin,在感染后第1、2和3天每天给药两次,每次2小时。在气溶胶室中使用于25nM NaHCO3中的4.5mg/ml化合物16,在感染前给药4小时并在感染后第1、2和3天给药8小时,与化合物16相同方式使用的空白对照为水。在第4天处死动物,灌洗动物的肺,确定灌洗中的RSV效价。在实验2中,感染的未处理的动物和曝露于25mM NaCO3气溶胶中的动物用作对照。制备于25mM NaCO3中的5mg/ml实施例1和4的化合物。其中一组在感染前第0天利用实施例1化合物处理4小时,在第1、2和3天处理8小时(预防方式)。另一组仅在第1、2和3天甩实施例1化合物处理8小时(治疗方式)。最后一组在第1、2和3天另一实施例4化合物处理8小时(治疗方式)。在第4天处死动物,灌洗肺,确定灌洗中的RSV效价。在实验3中,通过鼻内每天给药一次空白对照是水。通过在接种前及之后第1天(第0天和第1天)鼻内给药、在接种前及第1-3天鼻内给药以及仅在接种后1-3天鼻内给药,试验实施例4化合物。也通过腹膜内给药试验化合物。在第4天处死所有的动物,灌洗肺,确定灌洗中的RSV效价。这是通过对在vero细胞中产生细胞病变效应(CPE)的稀释终点(end-point)的测定以及通过vero细胞中的蚀斑试验进行的。将肺均化,通过离心出颗粒状材料(1000×g,10分钟)并使用蚀斑试验的上清液的稀释液,确定肺中的病毒效价。由此可看出实施例1和4化合物抑制了体内RSV。
