This invention provides compounds and pharmaceutical compositions that include compounds of the formula: ##STR1## in which 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, W is O or S; X is O, S, or CH.sub.2 ; Y is a purine or pyrimidine base, Z is C, S, or O, and wherein when Z is S or O, A and C are not present. The compounds of this inverntion have enhanced pharmaceutical or biological activity or increased intracellular absorption compared to the corresponding parent nucleoside as a function of the 5'-diphosphohexose moiety. Many of these compounds have antiviral, including anti-HIV, activity. Others have antibacterial activity. In one embodiment, the invention is a method to treat HIV infection and opportunistic infections concomitantly.
本发明提供了一种化合物和制药组合物,其中包括式子的化合物:##STR1## 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可以被双键替换;R是醛基己糖、醛基己糖胺或N-乙酰基醛基己糖胺,W是O或S;X是O、S或CH.sub.2;Y是
嘌呤或
嘧啶碱基,Z是C、S或O,其中当Z是S或O时,A和C不存在。这些化合物具有增强的制药或
生物活性或与相应的母核苷酸相比具有增加的细胞内吸收能力,这是由于5'-二
磷酸己糖基团的功能。这些化合物中的许多具有抗病毒,包括抗HIV活性。其他具有抗菌活性。在一种实施方式中,本发明是一种同时治疗HIV感染和机会性感染的方法。
