title: Synthesis, anti-HIV and antitubercular activities of lamivudine prodrugs.
abstract: The synthesis of a novel series of lamivudine prodrugs involving N4-substitution with isatin derivatives is described. The in-vitro antiretroviral activities indicated that compound 3b was found to be equipotent to lamivudine with EC50 of 0.0742+/-0.04 microM. Lamivudine prodrugs bearing fluoroquinoles antibacterial showed 92-100% inhibition against Mycobacterium tuberculosis strain H37Rv at 6.25 microg ml(-1). At pH 7.4, 37 degrees C, the hydrolytic t(1/2) ranged between 120 and 240 min.
