6-(alkyn-1-yl)furo[2,3-d]pyrimidin-2(3H)-ones in which the rodlike acetylene spacer replaces the 4-substituted-phenyl ring at C6. Analogues with methyl, beta-d-ribofuranosyl, beta-d-arabinofuranosyl, and 2-deoxy-beta-d-erythro-pentofuranosyl substituents at N3 have been prepared. Long-chain derivatives at C6 in the 2'-deoxynucleoside series showed virus-encoded nucleoside kinase-sensitive anti-VZV activity. Surprisingly
在C6处带有长链烷基(或4-烷基苯基)取代基的呋喃[2,3-d]嘧啶-2(3H)-one的2'-脱氧核苷衍生物显示出显着的抗VZV(水痘带状疱疹病毒)效力和选择性,以及类似的2',3'-二脱氧核苷衍生物显示出抗HCMV(人类巨细胞病毒)活性。我们现在报告一种合成方法,该方法能够制备长链6-(炔基-1-基)呋喃并[2,3-d]嘧啶-2(3H)-,其中棒状乙炔间隔基取代了4-取代基-在C6的苯环。已经制备了在N 3处具有甲基,β-d-呋喃呋喃糖基,β-d-阿拉伯呋喃糖基和2-脱氧β-d-赤-戊呋喃糖基取代基的类似物。2'-脱氧核苷系列中C6处的长链衍生物显示病毒编码的核苷激酶敏感的抗VZV活性。令人惊讶的是,3-甲基-6-(辛基-1-基)呋喃[2,
