Description
技术领域
本发明涉及替诺福韦类衍生物,并提供了它们的制备方法及其在抗病毒活性中的应用。
背景技术
病毒感染是当前人类最常见的感染性疾病,抗病毒药物的研究也一直都是新药研究的重要课题。病毒是一种个体微小,结构简单,只含一种核酸(DNA或RNA),必须在活细胞内寄生并以复制方式增殖的非细胞型生物。病毒感染常因病毒种类、机体状态不同产生轻重不一的损伤或病毒性疾病。乙型肝炎病毒(HBV)、流行性感冒病毒(influenza virus)、人类免疫缺陷病毒(HIV)、SARS冠状病毒(SARS-CoV)等引起的病毒性感染疾病,对人类健康产生了巨大的危害。目前,除了提前注射疫苗预防病毒性感染疾病之外,对病毒性感染疾病的治疗主要通过抑制病毒的复制(吸附、注入、合成、装配及释放五大步骤)和宿主细胞的关键信号分子以达到抗病毒的目的。然而,现有抗病毒药物存在耐药性、毒性等诸多问题,因此,抗病毒药物研究仍然任重道远。
替诺福韦具有非常强的抗病毒活性,但由于替诺福韦的溶解性差,且人体难于吸收,导致替诺福韦不适合作为药物直接应用。研究发现,通过对替诺福韦结构进行改造,可有效改善其理化性质,并开发出抗病毒药物。近年来,以替诺福韦为母核进行前药开发的研究取得了重要进展,吉利德公司先后开发了富马酸替诺福韦二吡呋酯(TDF)及富马酸替诺福韦艾拉酚胺(TAF),这两款药物作为前药,自身并不具有抗病毒活性,但在进入人体后,它们均被水解并释放出替诺福韦而表现出抗病毒活性。
发明内容
本发明要解决的技术问题是:如何应用药物设计的基本理论,结合计算机辅助药物设计手段,设计并合成一系列具有抗病毒活性的替诺福韦类似物,并对其进行抗病毒活性筛选,以期获得较好的抗病毒药物。
本发明的另一个目的是提供制备这些化合物的方法。
本发明的进一步目的是提供这些化合物在抗病毒活性。
为解决上述问题本发明提供如下技术方案:
通式(I)的化合物、其药学上可接受的药用盐或其药学上可接受的药用盐的水合物:
其中,R1代表氢、烷基、芳基、烷基氨基或芳基氨基;R2代表氢、烷基、芳基、羟基、烷氧基、芳基氧基;R3代表氢、烷基、芳基;
n代表1-20的整数;
根据本发明,其药学上可接受的药用酸成盐是通式(I)化合物与下列酸形成的盐:硫酸、硝酸、盐酸、氢溴酸、氢碘酸、磷酸、甲酸、乙酸、丙酸、丁酸、丙二酸、己二酸、马来酸、柠檬酸、酒石酸、乳酸、甲磺酸、苯磺酸、对甲苯磺酸、门冬氨酸、奈二磺酸、草酸、苯甲酸、琥珀酸、樟脑磺酸、谷氨酸、天冬氨酸、苹果酸、水杨酸、抗坏血酸、异烟酸、扁桃酸、丙酮酸或富马酸。
