Mycobacterium tuberculosis and Mycobacterium avium infections cause the two most important mycobacterioses, leading to increased mortality in patients with AIDS. Various 5-substituted 2′-deoxyuridines, uridines, 2′-O-methyluridine, 2′-ribofluoro-2′-deoxyuridines, 3′-substituted-2′,3′-dideoxy uridines, 2′,3′- dideoxyuridines, and 2′,3′-didehydro-2′,3′- dideoxyuridines were synthesized and evaluated for their in vitro inhibitory activity against M. bovis and M. avium. 5-(C-1 Substituted)-2′- deoxyuridine derivatives emerged as potent inhibitors of M. avium (MIC 90 = 1-5 μg/mL range). The nature of C-5 substituents in the 2′-deoxyuridine series appeared to be a determinant of anti-mycobacterial activity. This new class of inhibitors could serve as useful compounds for the design and study of new anti-tuberculosis agents.
Synthesis and biological activity of 3'-azido- and 3'-amino substituted nucleoside analogs

The product distribution obtained in the reaction of 1-(5-0-trityl-0-mesyl-2-deoxy-β-D-erythro-pentofuranosyl)-2,4-(1H, 3H)-pyrimidinedione with lithium azide in N, N'-dimethylformamide at 100°C depends on the nature of the substituent in 5. The results may be explained by a difference in the acidity of the pyrimidinedione. The reaction of the more acidic nucleosides (X = I, F) appears to proceed preferentially through the 2,3'-anhydro intermediate, whereas for the less acidic products (X = H, CH3) direct nucleophilic displacement by the azide ion predominates. The different 3'-azidfo derivatives were reduced to 3'-amino compounds. All 3'-azido- and 3'-aminopyrimidine nucleosides were tested against herpes simplex virus, vaccinia and vesicular stomatitis virus and on murine L1210 cell growth. None of the substances exhibited significant activity.
