Synthesis and evaluation of novel 4-substituted styryl quinazolines as potential antimicrobial agents.

In an attempt to afford possible antibacterial and anti-human immunodeficiency virus (HIV) agents, a series of 22 novel styryl quinazoline-based heterocyclic entities were designed and synthesized. Various substituted aryl urea and thiourea cores were incorporated at position 4 of quinazoline, followed by styrylation of position 2, aiming at an augmented biological potential. The synthesized compounds were well characterized through IR, (1) H NMR, (13) C NMR and elemental analyses.

Synthesis and studies of new 2-(coumarin-4-yloxy)-4,6-(substituted)-S-triazine derivatives as potential anti-HIV agents.

Novel 2-(coumarin-4-yloxy)-4,6-(substituted)-s-triazine derivatives i. e., diaryltriazine (DATA) are reported as novel non-nucleoside reverse transcriptase inhibitors (NNRTIs), were synthesized and their activities against human immunodeficiency virus HIV-1 (III-B), HIV-2 (ROD), and the double RT mutant HIV-1 (K103N and Y181C) were assessed.
