The present invention relates to novel derivatives of 2'-deoxyuridine substituted in the 5-, 3'- or 5'-position by .alpha.-aminoacyl groups, to a process for their preparation and the drugs in which they are present. These derivatives have the following general formula: ##STR1## in which R is selected from an alkyl or alkenyl radical having from 1 to 4 carbon atoms, an aryl radical or a halogen, it being possible for said alkyl, alkenyl and aryl radicals to contain at least one halogen substituent, and a radical of the formula --NH--R.sub.1, in which R.sub.1 is an amino acid residue or a peptide residue containing from 2 to 6 amino acids; and R' and R" are selected from a hydroxyl radical and a radical of the formula --NH--R.sub.1, in which R.sub.1 is as defined above, with the proviso that R' and R" are not simultaneously --NH--R.sub.1 and that, when R is --NH--R.sub.1, R' and R" are simultaneously a hydroxyl group. Application: treatment of cancers and viral infections.
本发明涉及2'-去氧尿苷的新颖衍生物,其在5-、3'-或5'-位置被α-氨基酰基团取代,以及其制备过程和所含药物。这些衍生物具有以下通用公式:
其中R从含有1至4个碳原子的烷基或烯基基团、芳基基团或卤素中选择,其中所述烷基、烯基和芳基基团可能含有至少一个卤素取代基,以及公式--NH--R.sub.1中的基团,其中R.sub.1是含有2至6个氨基酸的氨基酸残基或肽残基;R'和R"从羟基基团和公式--NH--R.sub.1中选择,其中R.sub.1如上定义,但R'和R"不能同时为--NH--R.sub.1,当R为--NH--R.sub.1时,R'和R"同时为一个羟基团。应用:治疗癌症和病毒感染。
