Tri-substituted triazoles as potent non-nucleoside inhibitors of the HIV-1 reverse transcriptase

A new series of 1,2,4-triazoles was synthesized and tested against several NNRTI-resistant HIV-1 isolates. Several of these compounds exhibited potent antiviral activities against efavirenz- and nevirapine-resistant viruses, containing K103N and/or Y181C mutations or Y188L mutation. Triazoles were first synthesized from commercially available substituted phenylthio-semicarbazides, then from isothiocyanates, and later by condensing the desired substituted anilines with thiosemicarbazones.
