  Antioxidant and antibacterial evaluation of synthetic furomollugin and its diverse analogs

  摘要：

  Diverse furomollugin (3) and its analogs (11-22) were synthesized in high yields via ceric ammonium nitrate-catalyzed formal [3 + 2] cycloaddition as a key step. The in vitro antioxidant activities of synthesized compounds were determined by analyzing radical scavenging activities for 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, and hydrogen peroxide assays. The results showed that the synthesized furomollugin analogs had effective antioxidant power. Dihydronaphthofurans with 2-alkyoxy or 2-aryl group were the most potent radical scavengers in DPPH assay. Moreover, the antibacterial activities of those compounds were also evaluated and the highly active compounds were selected for further determination of minimal inhibitory concentrations (MICs). Compound 19 (MIC = 2 mu g/mL) was found to be highly active against the gram-negative bacteria Escherichia coli (KCTC-1924) than the Ampicillin standard (MIC = 4 mu g/mL). Compound 22 (MIC = 0.5 mu g/mL) inhibited gram-positive bacteria Staphylococcus aureus (KCTC-1916) growth as effectively as ampicillin (MIC = 0.5 mu g/mL).

  A novel approach was developed for the synthesis of diverse dihydronaphtho[1,2-b]furans from 1,4-naphthoquinones and olefins in the presence of ceric ammonium nitrate. This reaction provides a rapid route for the synthesis of a variety of dihydronaphtho[1,2-b]furans and naphtho[1,2-b]furans bearing different substituents. This methodology was also used to synthesize the biologically important natural
