Synthesis and antiviral evaluation of bis(POM) prodrugs of (E)-[4′-phosphono-but-2′-en-1′-yl]purine nucleosides
摘要:
Seventeen hitherto unknown bis(POM) prodrugs of novel (E)-[4'-phosphono-but-2'-en-1'-yl]purine nucleosides were prepared in a straight approach and at good yields. Those compounds were synthesized by the reaction of purine nucleobases directly with the phosphonate synthon 3 bearing POM biolabile groups under Mitsunobu conditions. All obtained compounds were evaluated for their antiviral activities against a large number of DNA and RNA viruses including herpes simplex viruses 1 and 2, varicella zoster virus, Feline herpes virus, human cytomegalovirus, HIV-1 and HIV-2. Among these molecules, some of them exhibit anti-VZV and anti-HIV activity at submicromolar concentrations. This class of compound will be of further interest for lead optimization as anti-infectious agents. (C) 2012 Elsevier Masson SAS. All rights reserved.

synthetic step. All novel compounds were evaluated for their antiviralactivities against a large number of DNA and RNA viruses including herpes simplex virus type 1 and 2, varicella zoster virus, feline herpes virus, human cytomegalovirus, hepatitis C virus (HCV), HIV-1 and HIV-2. Among these molecules, only compound 31 showed activity against human cytomegalovirus in HEL cell cultures with at EC50
一系列迄今未知的 ANP 类似物,带有 ( E )-but-2-enyl 脂肪族侧链和修饰的杂环碱基,例如胞嘧啶和 5-氟胞嘧啶、2-吡嗪甲酰胺、1,2,4-三唑-3-甲酰胺或4-取代-1,2,3-三唑通过烯烃无环交叉复分解作为关键合成步骤直接制备。 评估了所有新化合物对大量 DNA 和 RNA 病毒的抗病毒活性,包括单纯疱疹病毒 1 型和 2 型、水痘带状疱疹病毒、猫疱疹病毒、人类巨细胞病毒、丙型肝炎病毒 (HCV)、HIV-1 和 HIV -2。在这些分子中,只有化合物31在 HEL 细胞培养物中显示出对人巨细胞病毒的活性,EC 50为~10 μM。化合物8a、13、14和24在100 μM时表现出显着的抗 HCV 活性而没有显着的细胞毒性。
