title: In vitro anti-mycobacterial activities of various 2'-deoxyuridine, 2'-arabinouridine and 2'-arabinofluoro-2'-deoxyuridine analogues: synthesis and biological studies.
abstract: M. tuberculosis, M. bovis and M. avium infections cause the most important mycobacterioses leading to increased mortality in patients with AIDS. Various 5-substituted 2'-deoxyuridines, arabinouridines, arabinocytidines and 2'-arabinofluoro-2'-deoxyuridines were synthesized and evaluated for their in vitro inhibitory activity against M. bovis, M. tuberculosis and M. avium. 5-(C-1 Substituted)-2'-deoxyuridine derivatives emerged as potent inhibitors of M. avium (MIC50 = 1-10 microg/mL range); 5-(1-azidovinyl)-2'-deoxyuridine being the most active (MIC50 = 1-5 microg/mL range). The nature of C-5 substituents appeared to be a determinant of anti-mycobacterial activity.
