Abstract
A series of new tetracycline derivatives has been synthesized by reacting appropriate tetracyclines, formaldehyde and secondary amino (piperazino) function of fluoroquinolones using microwave irradiation with the yield ranging from 41 evaluated for its anti-HIV, antimycobacterial activities and HIV-1 integrase (IN) enzyme inhibition studies. Among the synthesized compounds, compound 10 was found to be the most promising compound active against HIV-1 replication with EC(50) of 5.2 microM and was nontoxic to the CEM cells until 200 microM, and MIC of 0.2 microg/mL against Mycobacterium tuberculosis, with moderate inhibition of both 3'-processing and strand transfer steps of HIV-1 IN.
