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.

Phellinone, a new furanone derivative from thePhellinus linteus KT&G PL-2

Archives of Pharmacal Research, 2007
Phellinone, a new furanone derivative, has been isolated from the stem-cooked rice culture broth of Phellinus linteus KT&GPL-2. Phellinone was purified by consecutive solvent partition, silica gel, preparative TLC and preparative HPLC. The structure of phellinone was assigned as a furanone derivative on the basis of various spectroscopic analyses ...

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).

Mechanism of electrochemical reduction of 5-thio derivatives of 2(5H)-furanone

Russian Chemical Bulletin, 2019
© 2019, Springer Science+Business Media, Inc. The anionoid elimination of the substituent from position 5 of the lactone ring is the predominant pathway of electrochemical reduction of 5-arylsulfanyl- and 5-arylsulfonyl-3,4-dichloro-2(5H)-furanones in acetonitrile.

Phæniceroside, the first natural bis-furanone propane derivative from juniperus phænicea L.

Tetrahedron Letters, 1996
Abstract Phaeniceroside 1 or 2,2-bis-(5-methyl-4-( O -β-D-glucopyranosyl)-3(2H)-furanone)-propane have been isolated from Juniperus phaenicea L. (Cupressaceae). The structural elucidation of this new natural product was achieved by UV, MS, 1 H, 13 C NMR spectroscopy. The structure was confirmed by chemical way.

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.

Development of Fimbrolides, Halogenated Furanones and their Derivatives as Antimicrobial Agents

2015
Traditional treatment for bacterial infection is based on compounds that target bacterial viability or growth. However, a major concern with this approach is the frequent development of drug-resistant mutants. The discovery of bacterial quorum sensing (QS) systems, which control fundamental processes involved in bacterial physiology and virulence, has ...
