We report the synthesis of 5'-modified thymidines (16, 18, 21, 23) and 5,5'-bis-substituted 2'-deoxyuridine analogues (30, 47) as inhibitors of thymidine monophosphate kinase of Mycobacterium tuberculosis (TMPKmt). These analogues were evaluated for their capacity to inhibit TMPKmt and solely two 5'-modified thymidines were found to possess moderate inhibitory activity. In addition, a feasibility study of protecting groups for the 5-CH(2)OH moiety of 2'-deoxyuridines is described that enables to introduce the desired 5'-modification.

UI MeSH Term Description Entries
D009169 Mycobacterium tuberculosis A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation. Mycobacterium tuberculosis H37Rv
D009703 Nucleoside-Phosphate Kinase An enzyme that catalyzes reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside monophosphate, e.g., UMP, to form ADP and UDP. Many nucleoside monophosphates can act as acceptor while many ribo- and deoxyribonucleoside triphosphates can act as donor. EC 2.7.4.4. Nucleoside Monophosphate Kinases,Kinase, Nucleoside-Phosphate,Kinases, Nucleoside Monophosphate,Monophosphate Kinases, Nucleoside,Nucleoside Phosphate Kinase
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000995 Antitubercular Agents Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.
