We report the synthesis of a family of d- and l-furano-d-apionucleosides, their 3′-deoxy, as well as their 2′,3′-dideoxy analogues with thymine and adenine nucleobases. Single carbon homologation of 1,2-O-isopropylidene-d-glycero-tetrafuranos-3-ulose (15) and optimized glycosylation conditions involving microwave irradiation were key to the successful synthesis of the target compounds. While all target
我们报告了一个合成的d-和1- furano- d -apionucleosides,他们的3'-脱氧,以及他们的2',3'-dideoxy类似物与胸腺嘧啶和腺嘌呤核苷碱基的合成。的单碳同系化1,2- ö异亚丙基d -glycero-tetrafuranos -3-酮糖(15)和糖基化优化的条件涉及在微波辐射是关键的目标化合物的成功合成。尽管所有目标核苷均未显示出显着的抗病毒活性,但我们证明了2',3'-脱氧-d -apio- d-呋喃腺苷(1)的三磷酸与其d- apio-1-呋喃糖差向异构体2易于通过HIV逆转录酶掺入DNA模板中,以充当DNA链终止子。这导致我们将腺嘌呤衍生物1转化为两种氨基磷酸酯前药。发现ProTide 9b具有抗HIV-1和HIV-2的活性(EC 50 = 0.5–1.5μM),表明亲本核苷以及d- apio- d-呋喃糖核苷家族的其他成员缺乏活性必须寻求有效的细胞转化为一磷酸的方法。
