噻唑衍生物及其应用
相关申请的交叉引用
本申请主张2017.01.09提交的中国专利申请CN201710014893.9的优先权,其内容在此并入本申请。
技术领域
本发明涉及新的噻唑类化合物,尤其是式(I)所示化合物,其药物组合物及其在制备治疗与单纯疱疹病毒相关疾病的药物中的应用。
背景技术
在治疗病毒性疾病方面,对新的治疗方法有很大的需求。虽然在开发各种细菌感染的治疗方法方面已经取得了很大的进展,但是对于病毒的治疗还鲜有可行的治疗方法。齐多夫定是已经得到认可的用于治疗人类免疫缺损病毒的主要品种。目前使用更昔洛韦、阿昔洛韦和膦甲酸来治疗疱疹病毒感染。然而,由于这些治疗方法损害宿主细胞DNA的复制或者只对有限数量的病毒感染发生作用,因而具有相当大的副作用。另外,已知病毒能发展出对治疗的抗性,使得治疗效果日益下降。
疱疹病毒科是一族DNA病毒,包括单纯疱疹病毒-1型(HSV-1)、单纯疱疹病毒-2型(HSV-2)、巨细胞病毒(CMV)、水痘-带状疱疹病毒(VZV)、Epstein-Barr病毒、人类疱疹病毒-6(HHV6)、人类疱疹病毒-7(HHV7)、人类疱疹病毒-8(HHV8)、假狂犬病毒和鼻气管炎病毒等。

2.2.用ECHO 555液体工作站将化合物加入到接种有细胞的384孔板中。每个测试化合物测定8个浓度,双复孔。对于细胞对照孔,不加化合物与病毒。对于病毒对照孔,不加入化合物。所有孔中
DMSO的终浓度均为0.5%。
2.3.用实验培养基稀释病毒,接种量为1.5TCID 90/well,30μl。用Multidrop将实验培养基加入细胞对照孔,每孔30μl,再将稀释好的病毒用Multidrop加入化合物测试孔和病毒对照孔,每孔30μl。
2.4.将细胞板放入37℃,CO 2细胞培养箱培养5天。
3.细胞活性检测(Day.7)
3.1.培养5天后,观察细胞板所有孔中的细胞病变情况,细胞对照孔中的细胞应该没有发生病变,而病毒对照孔中的细胞几乎全部发生病变。
3.2.用Multidrop将CCK8加入细胞板中,每孔加入6μl。
3.3.将细胞板放入37℃,CO 2细胞培养箱孵育3小时。
3.4.用酶标仪读取细胞板每个孔的吸光值,所用波长为450nm,并使用630nm作为参比波长。原始数据值为450nm处的吸光度减去630nm处的吸光度(Raw data=OD 450-OD 630)。
4.数据分析
4.1.使用下面的方程式计算测试化合物的抗病毒活性(%Inhibition):
Figure PCTCN2018071964-appb-000112
其中,Sample为化合物测试孔的吸光值,cell control为细胞对照孔吸光值的平均数,virus control为病毒对照孔吸光值的平均数。
4.2.使用GraphPad Prism软件绘制剂量-效应曲线,并得出测试化合物的半数有效浓度(EC 50)。
5.实验结果见表1

6.结论:本发明化合物对抗单纯疱疹病毒(HSV)的抗病毒活性良好。
实验例2:化合物药代动力学评价
实验目的:测试化合物在小鼠体内药代动力学
实验材料:
Balb/c小鼠(雄性,18-22g,6~8周龄,上海斯莱克)
实验操作:
以标准方案测试化合物静脉注射及口服给药后的啮齿类动物药代特征。候选化合物配置成相应溶液,给予单次静脉注射(1.0mg/kg,5%DMSO/95%的20%羟丙基-β-环糊精)或灌胃(1.0mg/kg,0.5%甲基纤维素MC4000)给药。收集24小时内的全血样品,3000g离心15分钟,分离上清得血浆样品,加入4倍体积含内标的乙腈溶液沉淀蛋白,离心取上清液加入等倍体积的水再离心取上清进样,以LC-MS/MS分析方法定量分析血药浓度,并计算药代参数,如达峰浓度,达峰时间,清除率,半衰期,药时曲线下面积,生物利用度等。
实验结果如表2:
表2.药代动力学测试结果
Figure PCTCN2018071964-appb-000115
结论:本发明化合物,活性更优。在小鼠灌胃给药的体内药代动力学研究中,相同起效剂量下的血浆暴露量更低,安全性更好。
