Abstract:

Azoles are a promising class of the new generation of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs). From thousands of reported compounds, many possess the same basic structure of an aryl substituted azole ring linked by a thioglycolamide chain with another aromatic ring. In order to find novel extensions for this basic scaffold, we explored the 5-position substitution of triazole NNRTIs using molecular docking followed by synthesis of selected compounds. We found that heterocyclic substituents in 5-position of the triazole ring are detrimental to the inhibitory activity of compounds with 4-membered thioglycolamide linker. This substitution seems to be viable only for compounds with shorter 2-membered linker such as in derivatives of 4‐benzyl‐3‐ (benzylsulfanyl) ‐5‐ (thiophen‐2‐yl)‐4H‐1,2,4‐triazole reported earlier. A new scaffold of 2‐ [(4‐benzyl‐5‐methyl‐4H‐1,2,4‐triazol‐3‐yl) sulfanyl]‐N‐phenylacetamide has been identified in this study.
