Description
技术领域
本发明涉及1,3-二氧代茚衍生物、其药学上可接受的盐或光学异构体,其制备方法以及包含该衍生物用于预防和治疗病毒性疾病的药物组合物。
背景技术
小核糖核酸病毒(picornavirus)是具有7.2-8.5Kb长的RNA基因组的未包被的正单链RNA病毒。这些病毒非常小且形状为球形,尺寸为约22~30nm,很久以前被首次鉴别。肠病毒为属于小核糖核酸病毒科的病毒,其包括鼻病毒、脊髓灰质炎病毒、柯萨奇病毒(coxsackievirus)A、柯萨奇病毒(coxsackievirus)B和艾柯病毒(echovirus)以及甲型肝炎病毒。
小核糖核酸病毒引起的疾病是各种各样的,其范围从呼吸系统疾病到消化系统疾病,到循环系统疾病,以及到皮肤病,其例子包括脊髓灰质炎、麻痹、急性出血性结膜炎、病毒性脑膜炎、手足口病、水疱病、甲型肝炎、肌炎、心肌炎、胰腺炎、糖尿病、流行性肌痛、脑炎、流感、疱疹性咽峡炎和口蹄疫。然而,并没有用于治愈这些疾病的治疗方法。大多数在研究的药物为脱壳抑制剂(uncoating inhibitor)。属于小核糖核酸病毒科的病毒引起包括上述呼吸系统疾病的各种疾病,其引发卫生、社会和经济问题。小核糖核酸病毒为水传播疾病的主要病原体。RNA病毒非常稳定且难以被杀灭,其不断地导致相关的疾病。
最近,人鼻病毒(hRV)已经与大多数哮喘发作相关联,已知其甚至存在于许多稳定的哮喘病人的支气管组织中。分别来自哮喘和非哮喘病人的支气管粘膜活检样本的比较显示,相比非哮喘病人,哮喘病人的下呼吸道中的人鼻病毒的检出频率明显更高。还有报道称人鼻病毒的存在和哮喘的临床严重程度有相关性。此外,鼻病毒引起慢性阻塞性肺病、肺炎、鼻窦炎、中耳炎和哮喘。
鼻病毒是普通感冒的主要原因,而肠病毒诱导的疾病包括脑膜炎、呼吸道感染等。提供对抗脊髓灰质炎病毒的疫苗接种的广泛努力显著降低了全球范围脊髓灰质炎的发生,但是在尼日尔、尼日利亚、埃及、印度、巴基斯坦和阿富汗还有病例的报道。甲型肝炎病毒现在能够控制到某种程度是归功于甲型肝炎病毒疫苗。然而,到现在为止还没有开发出用于柯萨奇病毒、艾柯病毒或鼻病毒的疫苗。
特别是柯萨奇病毒B是心肌炎的主要原因,在严重的情况下,其可以发展成特发性扩张型心肌病,需要心脏移植。
恩韦肟(Enviroxime)衍生物被认为是具有广泛抗肠病毒和抗鼻病毒活性的最有希望的候选物。恩韦肟通过结合到病毒复制中形成RNA中间体所需的病毒蛋白3A干扰正链RNA的合成(Heinz B A and Vance L M:JVirol,1995,69(7),4189-97)。然而在临床研究中,观察到化合物的治疗效果不明显或很小,并同时发现药代动力学差和不需要的副作用(Miller FDet al.:Antimicrob Agents Chemother,1985,27(1),102-6)。
基于病毒蛋白酶2C的精细结构和功能的知识,已经开发了蛋白酶抑制剂AG7088。在纳摩尔浓度范围的细胞培养物中,AG7088具有抗48种鼻病毒类型和柯萨奇病毒A21、B3,肠病毒70和艾柯病毒11的效果(Pattick A K et al.:Antimicrobila Agents Chemother,1999,43(10),2444-50).
由于阐明了病毒衣壳的分子结构,有目的用于衣壳阻断剂的设计的先决条件,即“WIN物质(substance)”已经得到(Diana G D:Curr Med Chem2003,2,1-12)。它们抑制鼻病毒和肠病毒的吸附和/或脱壳。一些WIN物质仅具有对抗小核糖核酸病毒的个别属或病毒类型的高特异性效果。其它衍生物抑制鼻病毒和肠病毒的复制。例如,阿立酮(Arildone)、二噁沙利(disoxaril)和吡罗达韦(pirodavir)属于WIN物质。这些化合物在细胞培养物中显示出非常好的抗病毒效果。然而,溶解性差(阿立酮)、低生物利用度(阿立酮和二噁沙利)、快速代谢和排泄(二噁沙利和WIN54954)以及副作用,如皮疹(WIN54954)使其不可能临床应用。
一种WIN物质,普来可那利(Pleconaril),具有非常好的口服生物利用度,在其结合至病毒衣壳中的疏水口袋后,其抑制鼻病毒、艾柯病毒和柯萨奇病毒的侵入(Pevear D C et al.:Antimicrob Agents Chemother1999,43(9),2109-15;McKinlay M A et al.:Annu Rev Microbiol 1992,46,635-54)。因此,普来可那利对抗广谱病毒性疾病是可能有效的,所述病毒性疾病的范围从普通感冒至病毒性脑膜炎或心肌炎。观察到对鼻病毒、肠病毒71和柯萨奇病毒B3的抗性(Ledford R M et al.:J Virol2004,78(7),3663-74;Groarke J M et al.:J Infect Dis1999,179(6),1538-41)。然而,证明的治疗效果不足以用于将普来可那利(Picovir,Viropharma,美国)在美国注册为用于治疗鼻病毒感染的药物。2002年3月,食品和药物管理局(FDA)拒绝了相应的申请,因为治疗成功率太低且观察到副作用。
当采用鼻病毒进行体外和体内评价时,发现BTA-798具有比普来可那利更高的抗病毒活性,其现在正处于临床试验中(Ryan,J.et al.AntiviralRes[18th Intl Conf Antiviral Res(April 11-14,Barcelona)2005]2005,65(3):Abst LB-11)。
然而,到目前为止,还没有开发出获准用于治疗肠病毒或鼻病毒的抗病毒药物。
集中和深入地研究对抗包括柯萨奇病毒、肠病毒、艾柯病毒、脊髓灰质炎病毒和鼻病毒的小核糖核酸病毒的有效病毒抑制剂,最终发现了表现出对抗包括柯萨奇病毒、肠病毒、艾柯病毒、脊髓灰质炎病毒和鼻病毒的小核糖核酸病毒的高抑制活性的新型1,3-二氧代茚衍生物,从而形成了本发明。

表1中示出了实施例1至108的化合物的化学式。
表1
<实验例1>针对抗小核糖核酸病毒的抗病毒活性的细胞病变效应(CPE)抑制试验
在试验中,使用HeLa细胞(人宫颈癌细胞),MRC-5细胞(人胚胎肺成纤维细胞)和RD细胞(获自人横纹肌肉瘤)。为了进行比较,采用利巴韦林(Riv)、普可那利(pleco)和BTA-798(BTA)作为对照。将试剂以10~40mg/ml的浓度溶解于100%的二甲基亚砜(DMSO)中。水溶性试剂溶解于PBS(-)溶液中并在-20℃下储存。在实验当天,试剂以3x至5x的浓度使用以使各孔中二甲基亚砜的浓度为0.5%至1%。
利用病毒诱导的细胞病变效应(CPE)抑制试验确定药效。在这方面,在适于病毒的细胞在96孔板中生长后,将补加有2%FBS(DME/2%FBS)的DME或补加有2%FBS(MEM/2%FBS)的MEM中的病毒稀释液以100μl的量(其浓度对应于100CCID50(50%的细胞培养物感染剂量))接种到板的各孔中,并在33℃或37℃下培养30分钟至1小时,以使病毒吸附至细胞。在将各种浓度的等份药稀释液以100μl的量加入各孔之前去除培养基。当HRV在33℃下生长时,将其他病毒在37℃的CO2培养箱中培养2~3天。或者,向细胞加入50μl具有2倍较高浓度的各种药物稀释液,然后加入50μl病毒稀释液后,在不去除培养基的情况下培养细胞2~3天。
以下表2中总结了各病毒的测试条件。
表2
对于HeLa细胞,采用MTT试验测试药物的EC50(50%最大有效浓度),EC50为诱导基线和最大值之间的响应至一半的药物浓度。关于RD和MRC-5细胞,使用FDA(荧光素二乙酸酯)确定CPE。为使药物效力的评价结果反映该药物的毒性作用,以相同的方式处理模拟感染的细胞,通过向细胞加入无病毒的培养基制备模拟感染的细胞。也就是说,培养一小时后除去培养基,再次加入药物的培养基稀释液。培养2~3天后,在显微镜下观察细胞,并使用MTT试验确定药物的CC50(50%的细胞毒性浓度),MTT试验中,将包含药物的模拟感染的孔中的活细胞计数与不包含药物的对照孔中的活细胞计数比较。在FDA水解试验中,除去培养基后将FDA加入各孔中,并在使用荧光分光计测定荧光强度之前培养20~30分钟,以与MTT中相同的方式确定CPE。
使用以下数学式1计算模拟感染的细胞的存活率(%存活):
[数学式1]
100%的细胞存活率意味着药物无细胞毒性,而0%的细胞存活率反映了最高的细胞毒性。50%的细胞毒性浓度(CC50)被定义为与未处理的对照相比细胞数降低50%所需的浓度。较高的CC50值意味着较低的细胞毒性。
此外,可以使用以下数学式2计算抗病毒效果:
[数学式2]
100%的存活率意味着最好的抗病毒效果(100%),而存活率为0%的药物被认为缺乏抗病毒效果。记录病毒细胞病变效应(CPE),50%的有效浓度(EC50)被定义为与未处理的对照相比病毒CPE减少50%所需的化合物浓度。较低的EC50值意味着较高的抗病毒活性。
表3和表4分别给出了说明细胞毒性和抗小核糖核酸病毒的抗病毒活性的化合物的CC50和EC50值。
表3
表4
从表3和表4的数据可知,大多数本发明的1,3-二氧代茚衍生物表现出低细胞毒性,因为它们具有高CC50值。此外,发现大多数本发明的1,3-二氧代茚衍生物对柯萨奇病毒、脊髓灰质炎病毒、鼻病毒和肠病毒具有强抑制性,因为它们的EC50值为0.01μg/mL或更低。
相应地,根据本发明的化学式1所示的1,3-二氧代茚衍生物表现出低细胞毒性和对抗广谱小核糖核酸病毒的高抑制活性,因此可以有效地应用于用于预防或治疗小核糖核酸病毒引起的疾病的药物组合物。
<实验例2>针对抗小核糖核酸病毒的抗病毒效果的多循环细胞病变效应(CPE)减少试验
通过多循环细胞病变效应(CPE)减少试验评价测试化合物的抗小核糖核酸病毒活性。首先使用基于MTS[3-(4,5-二甲基噻唑-2-基)-5-(3-羧基甲氧基苯基)-2-(4-磺苯基)-2H-四唑]的CPE减少试验确定抗病毒活性。
在这一方面,将生长至覆盖96孔板的细胞用10050%的细胞培养物病毒感染剂量(CCID50)感染。在37℃下2小时的吸附时间后,除去病毒并加入化合物的系列稀释液。将培养物在37℃下再培养3天,直到在感染的和未处理的病毒对照(VC)中观察到完全的CPE。除去培养基后,向各孔加入90μl培养基和10μl的MTS-吩嗪硫酸甲酯(普洛麦格(Promega),莱顿(Leiden),荷兰)。在37℃下2小时的孵育期后,用酶标仪在498nm下读出各孔的光密度(OD)。
使用以下数学式3计算用于评价抗病毒活性的CPE值:
[数学式3]
使用以下数学式4计算用于评价细胞毒性的CPE值:
[数学式4]
在式3和4中,
ODcc对应于未感染的和未处理的背景细胞培养物的OD,
ODVC表示感染的和未处理的对照细胞培养物的OD,
OD病毒+化合物表示用给定浓度的化合物处理的病毒感染的细胞培养物的OD,以及
OD空白表示单独加入细胞培养基的孔的OD。
50%有效浓度(EC50)和50%细胞毒性浓度(CC50)被分别定义为提供50%对抗病毒诱导的CPE的保护以及杀死50%的细胞的化合物浓度,采用对数内插法计算。
以下表5中给出了一些化合物对抗各种病毒的CC50和EC50。
