Abstract |
A series of 5-alkylamino and 5-alkylsulfanyl derivatives of 1-aryl-2-alkyl-4-nitro-1H-imidazoles 12-21, 31, and 34 were synthesized by a simple method with the aim to develop novel HIV non- nucleoside reverse transcriptase inhibitors (NNRTIs). All the new compounds were tested against HIV-1 and HIV-2 in MT-4 cells. Compound 21, with an arylsulfanyl group at C(5) of the 4-nitro-1H-imidazole backbone showed an EC(50) value of 0.22 microg/ml against HIV-1 with a therapeutic index of 13. This means that compound 21 was cytotoxic to MT-4 cells at a CC(50) value of 2.57 microg/ml; also compounds 8, 22-25, 28, and 29 were cytotoxic to MT-4 cells within the 0.4-4 microg/ml concentration range. Compounds 8, and 12-21 were evaluated, as a rule, but found inactive at non-toxic concentrations against hepatitis C virus, herpes simplex type 1 and 2, cytomegalovirus (CMV), varicella-zoster virus (VZV), vaccinia virus, and vesicular stomatitis virus, and a number of other viruses. Yet, the therapeutic index of compounds 17 and 21 for CMV and VZV approached the tenfold cut-off point. Compounds 8 and 21 exhibited some cytostatic activity against leukemia and melanoma cell lines.
