Antibacterial effects and genotoxicity of new derivatives of furanones

2012
New chlorine-containing furanones were tested for the presence of antibacterial activity and also for genotoxicity in Ames test. It has been established that the tested compounds had antibacterial properties. Antibacterial activities of all four compounds differed in rich broth and minimal glucose media.

Design, synthesis, and In vitro antituberculosis activity of 2(5H)-Furanone derivatives.

IUBMB life, 2017
A series of 2(5H)-furanone-based compounds were synthesized from commercially available mucohalic acids. From the first-generation compounds, three showed inhibitory activity (10 µg/mL) of at least 35% against Mycobacterium smegmatis mc(2) 155 growth (Bioscreen C system).

Synthesis of chiral 2(5H)-furanone derivatives with 1,3-butadiyne structure

Research on Chemical Intermediates, 2012
Using CuI as a catalyst, N,N-diisopropylethylamine as ligand, n-butylamine as a base, and CH3CN as solvent, the Glaser reaction of N-[5-(S)-alkoxy-2(5H)-furanonyl] amino acid propargyl esters 1 at room temperature was investigated, and a series of new chiral 2(5H)-furanone derivatives containing 1,3-butadiyne structure have been synthesized as designed,

Mono- and bis-furanone derivatives from the endolichenic fungus Peziza sp.

Fitoterapia, 2014
Seven new mono- and bis-furanones, pezizolides A-G (1-7), have been isolated from the crude extract of the endolichenic fungus Peziza sp. inhabiting the lichen Xanthoparmelia sp. The structures of the new compounds were elucidated mainly by NMR and MS methods.
