Two sets of pyrimidine nucleoside derivatives bearing extended alkyloxymethyl or alkyltriazolidomethyl substituents at position 5 of the nucleobase were synthesized and evaluated as potential antituberculosis agents. The impact of modifications at 3'- and 5'-positions of the carbohydrate moiety on the antimycobacterial activity and cytotoxicity was studied. The highest effect was shown for 5-dodecyloxymethyl-2'-deoxyuridine, 5-decyltriazolidomethyl-2'-deoxyuridine, and 5-dodecyltriazolidomethyl-2'-deoxycytidine. They effectively inhibited the growth of two Mycobacterium tuberculosis strains in vitro, laboratory H37Rv (MIC99 = 20, 10, and 20 mu g/mL, respectively) and clinical MDR MS-115 resistant to five top antituberculosis drugs (MIC99 = 50, 10, and 10 mu g/mL, respectively).
