Popis: In the present study, a series of novel 5,7-diisoprenyloxyflavone derivatives were designed, synthesized, and evaluated for their antibacterial activity. Most of these compounds displayed significant antibacterial effects against Gram-positive bacteria, especially against strains of multidrug-resistant clinical isolates. Compounds 4c, 4g, 4i, 4j, 4k, 4l, 4n, 4q and 4t showed high levels of antimicrobial activity against Staphylococcus aureus RN4220 with minimum inhibitory concentrations of 4.0-20 μM. Compound 4k showed the most potent activity among these compounds against all multidrug-resistant clinical isolates tested. Unfortunately, none of the compounds were active against Gram-negative bacteria at the doses of 24-164 μM.
