Abstract

本发明涉及式I所示化合物、其消旋体或旋光异构体、其药学可接受的盐、溶剂合物、水合物,含有该化合物的药物组合物,及其在制备预防和/或治疗与病毒感染有关的疾病或病症的药物中的用途。

Description

一种4-氧代-4,5-二氢噻唑类衍生物、其制备方法和用途 技术领域
本发明属于医药化工领域,涉及新型广谱抗病毒感染药物及其在制备预防和/或治疗多种病毒引起的病毒性疾病药物中的用途。
背景技术
自从1899年马丁乌斯·贝杰林克首次提出病毒一词以来,迄今全世界已经有超过6000多种病毒得到鉴定,其中艾滋病毒、肝炎病毒、流感病毒、严重急性呼吸综合征(severe acute respiratoty syndromes,SARS)病毒、肠道病毒EV71以及正在西非各国肆虐的高致死率的埃博拉病毒等已成为人类健康的天敌。病毒在流行初期会即会造成巨大的危害,包括人员的损伤、社会的恐慌、经济的波动等,给国民经济和社会安定造成严重影响。此时即便是只有微弱治疗作用的防治药物,也会对人员损伤的减少,尤其是安定社会的恐慌和经济波动起到难以估量的作用。而降低这种新发突发公共卫生安全事件危害最佳的选择,是发展广谱性的抗病毒的药物。
病毒的繁殖离不开宿主细胞,大部分病毒进入宿主细胞主要通过网格蛋白介导型内吞作用(Clathrin-mediated endocytosis,CME)、胞膜窖介导型内吞作用(Caveolin-mediated endocytosis)、网格蛋白和胞膜窖非依赖型内吞作用(Clathrin and Caveolin-independent endocytosis)以及巨胞饮作用途径(Macropinocytosis)。而CME作用是肠道病毒EV71、登革病毒、丙肝病毒等诸多病毒进入细胞的主要途径。由于其功能和机制与病毒本身无关,不易随病毒变异产生耐药,是近年来广谱抗病毒的潜在靶标。
在CME中,网格蛋白、衔接蛋白(adaptor protein,AP-2)与发动蛋白(dynamin)等都是必不可少的关键分子。目前病毒依赖网格蛋白介导型内吞作用入胞机制研究的比较清晰,整个内吞过程大体上可以分为四个阶段:
1)网格蛋白包被小窝核化(nucleation of clathrin-coated pits):此阶段需要FCHol/2、eps15和交叉蛋白-1复合体的参与,复合体在网格包形成前汇集在包被小窝核的位置,通过eps15上的诸多AP-2结合位点来募集AP-2。此后,网格蛋白再次被AP-2募集到胞质膜表面,使得网格蛋白的局部浓度 超过网格蛋白三腿复合体聚合的阈值浓度,开始进行小范围的网格蛋白包被的组装。网格蛋白在稳定网格蛋白包被小窝形状和牵引膜内陷是必不可少的。
2)在包被小窝里被转运体捕获(cargo capture in coated pits):病毒作为被转运体(cargo)与细胞膜表面识别病毒的特异受体结合而被捕获和扣留。网格蛋白网格的形成触发了衔接蛋白联合激酶1(adaptin-associated kinase 1,AAK1),此激酶可以磷酸化AP-2的μ2亚单位,使其更加牢固地结合到膜的磷脂酰肌醇二磷酸(PIP2),暴露μ2的被转运体结合位点。被转运体与AP-2结合的复合物可以激活PIPK Iγ,提高包被区膜的PIP2浓度,产生充足的与AP-2、epsin以及其他和CME有关的蛋白结合的膜位点,来维持网格蛋白包被小窝(clathrin-coated pits,CCP)的增长。
3)弯曲诱导与细胞膜内陷:膜最初的变形可能发生在网格蛋白包被小窝核化的阶段,FCHo通过F-BAR结构域使细胞膜产生一个小的弯曲。弯曲可能需要很多膜结合蛋白及网格蛋白包被的介导,其中包括epsin与amphiphysin等。包被附近的细胞膜弯曲,在细胞膜表面形成增长的芽,当细胞膜内陷出芽成囊泡状的时候,一个管状的颈部区开始在胞膜表面形成,此区域无被网格蛋白包被和包含自由的PIP2,但是仍有很高的弯曲率,可以吸引含有弯曲敏感N-BAR结构域的蛋白。
4)囊泡剪切和去包被(vesicle scission and uncoating):网格蛋白包被囊泡在拥有充足的弯曲度以后,发动蛋白能够在囊泡的颈部形成一个环状结构,通过GTP水解驱动机制产生向内挤压的力量,在amphiphysin等蛋白的参加下进行剪切囊泡,被剪切的囊泡很快即被去包被。去包被机制可能是前期endophilin募集具有磷酸酶活性的突触小泡磷酸酶到囊泡,进而破坏AP-2/PIP2之间的高亲和力,使得PIP2转化为PI(4)P,GAK/辅助蛋白(auxilin)可以通过PTEN样结构域结合到新形成的PI(4)P上并募集Hsc70伴侣分子到包被囊泡与AP-2及网格蛋白相互作用,进而完成囊泡去包被过程。失去包被的囊泡聚合或者直接地与内涵体进行融合,随后再与溶酶体融合,内容物被降解,膜受体与病毒配体进行分离,完成整个病毒入胞的过程。
因此,对网格蛋白进行抑制可以起到阻断病毒内吞进程的作用,本发明的目的在于合成新型网格蛋白抑制剂,以用于制备预防和/或治疗多种病毒引 起的病毒性疾病的广谱抗病毒药物。

15.2测试项目:化合物抑制网格蛋白内吞作用的活性评价
1.实验原理:转铁蛋白是网格蛋白介导的内吞作用的关键蛋白。因此,通过测定化合物对HeLa细胞中转铁蛋白的影响,可以评价化合物对网格蛋白介导的内吞作用的抑制作用。
2.样品处理:将受试化合物溶于DMSO配成母液,母液-20℃保存,临用前用HEPES缓冲液(25mm HEPES,20mm Glucose,1%BSA,灭菌 水)配成40mM初始浓度,再用培养液作2倍稀释,得到浓度为1.25-40μmol/L的6个稀释度。
4.测试方法:将HeLa细胞(中国科学院细胞库提供)接种于用0.1毫克/毫升的多聚赖氨酸包被的24孔培养板中,然后加入无血清培养基DMEM(Gibco公司),500μl/well,培养一夜。每孔分别加入0.5μl不同稀释度的受试化合物或0.1v/v%DMSO,预处理15min,随后加入20μg/ml alexa568转铁蛋白2μl(Transferrin,TF,SIGMA-ALDRICH公司),37℃孵育15分钟。然后用活细胞成像溶液(LCIS,Invitrogen公司)和低pH值的酸(含有0.5%乙酸的0.5M NaCl溶液)洗涤,依次各洗30秒,随后用冷的甲醇固定,在荧光显微镜下观察。
5.实验结果
测试了五种化合物,包括化合物3、10、13、14和pitstop2(Con1)对HeLa细胞中转铁蛋白内吞作用的影响。当HeLa细胞暴露在Alexa568转铁蛋白中时能高效地内吞转铁蛋白,并在核周分布。而化合物3、10、14和pitstop2表现出抑制转铁蛋白的内吞作用,且作用效果呈剂量依赖性。当20μM的化合物3、10、14作用于细胞后,HeLa细胞对转铁蛋白的内吞作用被完全抑制,抑制率见表3。
