PURPOSE HIV is the most significant risk factor for many opportunistic infections such as tuberculosis, hepatitis, bacterial infections and others. In this paper, we describe an aminopyrimidinimino isatin lead compound as a novel non-nucleoside reverse transcriptase inhibitor with broad-spectrum chemotherapeutic properties for the effective treatment of AIDS and AIDS-related opportunistic infections. METHODS The synthesis of various aminopyrimidinimino isatin derivatives was achieved in two steps and evaluated for anti-HIV, anti-HCV, antimycobacterial and antibacterial activities. RESULTS Compound 1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7[[N4-[3'-(4'-amino-5'-trimethoxybenzylpyrimidin-2'-yl)imino-1'-isatinyl] methyl]N1-piperazinyl]-3-quinoline carboxylic acid (14) emerged as the most potent broad-spectrum chemotherapeutic agent active against HIV, HCV, M. tuberculosis and various pathogenic bacteria. Among the synthesized compounds compound 14 and 15 emerged as more promising broad-spectrum chemotherapeutic agents.
