    • Compounds of the general formula: ##STR1## wherein A, B, and C are hydrogen, halogen, or azido; D is hydrogen, halogen, azido, or OH; A and B or C and D can be replaced with a double bond; R is an aldohexose, aldohexosamine, or N-acetyl aldohexosamine, R.sub.1 and R.sub.2 are hydrogen or alkyl groups of from C.sub.1 to C.sub.10 ; W is oxygen or sulfur; X is oxygen, sulfur, or CH.sub.2 ; Y is a purine or pyrimidine base, and Z is carbon, sulfur, or oxygen. Y can be any purine or pyrimidine base, natural or synthetic, which combines with a sugar to form a biologically active nucleoside. In combination with an appropriate pharmaceutical carrier, the compositions have enhanced activity or increased intracellular absorbment over the parent nucleoside as a function of the 5'-O-diphosphosugar. Another embodiment of the present invention is the enhancement of biologically active nucleosides into cells by preparing and administering the 5'-O-diphosphohexose, 5'-diphospho-N-acetylhexosamine or 5'-diphosphohexosamine derivative of the nucleoside. In the preferred embodiment for therapeutic use, the compounds are provided in a pharmaceutical carrier in an amount sufficient to exhibit as known in vitro or in vivo biological activity.
    • 通式的化合物:其中A,B和C是氢,卤素或叠氮基; D是氢,卤素,叠氮基或OH; A和B或C和D可以用双键替换; R是羟基己糖,醛双己糖胺或N-乙酰基己二胺,R1和R2是氢或C1至C10的烷基; W是氧或硫; X是氧,硫或CH 2; Y是嘌呤或嘧啶碱,Z是碳,硫或氧。 Y可以是天然或合成的任何嘌呤或嘧啶碱,其与糖结合以形成生物活性核苷。 与合适的药物载体组合,作为5'-O-二磷磷酸的功能,组合物具有增强的活性或增加的亲核苷的细胞内吸收。 本发明的另一个实施方案是通过制备和施用核苷的5'-二磷酸己糖,5'-二磷酸-N-乙酰基己糖胺或5'-二磷磷酰胺衍生物来增强生物活性核苷进入细胞。 在用于治疗用途的优选实施方案中,化合物以足以显示已知的体外或体内生物活性的量在药物载体中提供。
