The present invention is concerned wtih new 2'-isomeric 2 2',3'-dideoxy-2'.beta.-D-nucleosides and their derivatives where the base moiety has .beta.-stereochemistry but is transposed from the normal 1'-position to the 2'-position and the carbohydrate moiety has the D-configuration at the 4'-position. These compounds are resistant towards hydrolytic cleavage of the glycosidic bond and are resistant to enzymatic deamination. They have potential in the treatment or prophylaxis of viral infections, particularly retroviral infections and especially AIDS.
本发明涉及新的2'-异构体2,2',3'-二去氧-2'.β.-D-核苷和它们的衍
生物,其中碱基基团具有β-立体
化学,但从正常的1'-位置转移到2'-位置,而
碳水化合物基团在4'-位置具有D-构型。这些化合物对糖苷键的
水解裂解具有抗性,并且对酶催化的脱
氨基作用具有抗性。它们在治疗或预防病毒感染方面具有潜力,特别是对逆转录病毒感染,尤其是艾滋病具有潜在作用。
