The research focuses on the synthesis and evaluation of nine new indolyl glyoxamide derivatives (3a-i) as potential inhibitors of HIV-1. The compounds were synthesized by reacting benzylindoles (1) with oxalyl chloride to form glyoxylyl chlorides (4), which were then reacted with phenoxy phenylamines (2a or 2b) in the presence of triethylamine. The synthesized compounds were evaluated for their inhibitory activity against HIV-1 replication in acutely infected C8166 cells. The results showed that compounds 3e and 3h exhibited potent anti-HIV-1 activity with EC50 values of 6.83 and 4.35 μg/mL, and TI values of >27.15 and 49.45, respectively. The study also revealed that the introduction of substituents, particularly halogen atoms at specific positions, significantly influenced the compounds' activity. The research highlights the potential of these indolyl glyoxamide derivatives as new anti-HIV-1 agents.
