title: Synthesis, anti-HIV and antitubercular activities of isatin derivatives.
abstract: HIV is the most significant risk factor for many opportunistic infections like tuberculosis. In this study, we designed an isatinimino lead compound as a novel non-nucleoside reverse transcriptase inhibitor with antimycobacterial properties for the effective treatment of AIDS and AIDS-related tuberculosis. Among the compounds sythesized, 1-cyclopropyl-6-fluoro-8-methoxy-1,4-dihydro-4-oxo-7[[N4-[3'-[(4,6-dimethylpyrimidin-2-yl)benzenesulfonamido-4-yl]imino-1'-(5-fluoroisatinyl)]methyl]-3-methyl N1-piperazinyl]-3-quinoline carboxylic acid (9) emerged as the most potent broad-spectrum chemotherapeutic agent active against HIV (EC50: 12.1 microg/ml), and Mycobacterium tuberculosis (MIC: 1.22 microg/ml).
