In order to improve the antiproliferative activity of naringenin, a naturally occurred flavonoid in citrus fruits, a series of naringenin derivatives with a tertiary amino side chain were prepared. The antiproliferative activities of these naringenin derivatives were evaluated on four human cancer cell lines, namely, MCF-7, HCT116, Hela, and A549. Compounds 4a, 9a, and 10a exhibited remarkably enhanced growth inhibition activity. Based on the observed results, the structure–activity relationship of these derivatives was discussed.

Based on a rationally conceived pharmacophore model to build a multi-target bacterial topoisomerase inhibitor, twenty-one fluoroquinolone-flavonoid hybrids were synthesized. Some obtained hybrids show excellent antibacterial activity against drug-resistant microorganisms with narigenin-ciprofloxacin being the most active, showing 8, 43, 23 and 88 times better activity than ciprofloxacin against Escherichia coli ATCC 35218, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923 and Candida albicans ATCC 90873, respectively. Drug accumulation and DNA supercoiling assays of two active analogues revealed potent inhibition of both the DNA gyrase and efflux pump, confirming the desired dual mode of action. Molecular docking study disclosed that the introduced flavonoid moiety not only provides several additional interactions but also does not disturb the binding mode of the floxacin moiety. Our data also demonstrated that development of antifungals is possible from fluoroquinolones modified at C-7 position.
