Catalytic Undirected Intermolecular C-H Functionalization of Arenes with 3-Diazofuran-2,4-dione: Synthesis of 3-Aryl Tetronic Acids, Vulpinic Acid, Pinastric Acid, and Methyl Isoxerocomate

A variety of 3-aryl tetronic acids have been synthesized by an undirected, intermolecular C-H functionalization of arenes with 3-diazofuran-2,4-dione. This methodology featured as a key step in the synthesis of a series of naturally occurring 3-aryl-5-arylidene tetronic acids (pulvinates) from commercially available tetronic acid. Salient features of the pulvinic acid synthesis include a one-step, stereoselective synthesis of the C5 arylidene group and a single step introduction of the C3 aryl substituent.

Synthesis, molecular docking and biological evaluation of 3-arylfuran-2(5H)-ones as anti-gastric ulcer agent

3-Arylfuran-2(5H)-one derivatives show good antibacterial activity and were determined as tyrosyl-tRNA synthetase (TyrRS) inhibitors. In a systematic medicinal chemistry exploration, we demonstrated chemical opportunities to treat infections caused by Hel

Novel 3-arylfuran-2(5H)-one-fluoroquinolone hybrid: Design, synthesis and evaluation as antibacterial agent

3-Arylfuran-2(5H)-one, a novel antibacterial pharmacophore targeting tyrosyl-tRNA synthetase (TyrRS), was hybridized with the clinically used fluoroquinolones to give a series of novel multi-target antimicrobial agents. Thus, twenty seven 3-arylfuran-2(5H)-one-fluoroquinolone hybrids were synthesized and evaluated for their antimicrobial activities. Some of the hybrids exhibited merits from both parents, displaying a broad spectrum of activity against resistant strains including both Gram-negative and Gram-positive bacteria. The most potent compound (11) in antibacterial assay shows MIC50 of 0.11 μg/mL against Multiple drug resistant Escherichia coli, being about 51-fold more potent than ciprofloxacin. The enzyme assays reveal that 11 is a potent multi-target inhibitor with IC50 of 1.15 ± 0.07 μM against DNA gyrase and 0.12 ± 0.04 μM against TyrRS, respectively. Its excellent inhibitory activities against isolated enzymes and intact cells strongly suggest that 11 deserves to further research as a novel antibiotic.

A facile synthesis, antibacterial activity of pulvinone and its derivatives

Pulvinone and several 3-fluoro-4-morpholino substituted pulvinone derivatives were synthesized in five steps from a common precursor, phenyl acetic acid. Most of synthetic morpholine substituted pulvinones showed inhibitory activity against Esherichia col

Synthesis, structure, molecular docking, and structure-activity relationship analysis of enamines: 3-Aryl-4-alkylaminofuran-2(5H)-ones as potential antibacterials

Thirty-one 3-aryl-4-alkylaminofuran-2(5H)-ones were designed, prepared and tested for their antibacterial activity. Some of them showed significant antibacterial activity against Gram-positive organisms, especially against Staphylococcus aureus ATCC 25923, but all were inactive against Gram-negative organisms. Out of these compounds, 3-(4-bromophenyl)-4-(2-(4-nitrophenyl) hydrazinyl)furan-2(5H)-one (4a11) showed the most potent antibacterial activity against S. aureus ATCC 25923 with MIC50 of 0.42 μg/mL. The enzyme assay revealed that the possible antibacterial mechanism of the synthetic compounds might be due to their inhibitory activity against tyrosyl-tRNA synthetase. Molecular dockings of 4a11 into S. aureus tyrosyl-tRNA synthetase active site were also performed. This inhibitor snugly fitting the active site might well explain its excellent inhibitory activity. Meanwhile, this modeling disclosed that a more suitable optimization strategy might be to modify the benzene ring at 3-position of furanone with hydrophilic groups.

Tyrosyl-tRNA synthetase inhibitors as antibacterial agents: Synthesis, molecular docking and structure-activity relationship analysis of 3-aryl-4-arylaminofuran-2(5H)-ones

Thirty-five 3-aryl-4-arylaminofuran-2(5H)-one derivatives were designed, prepared and tested for their inhibitory activity against tyrosyl-tRNA synthetase. Out of these compounds, 3-(3-bromophenyl)-4-(3,5- dichlorophenylamino)furan-2(5H)-one (35) was the most active with IC 50 of 0.09 ± 0.02 μM. The structure-activity relationship revealed that introduction of chlorine atoms at both meta positions of aniline moiety significantly increased the enzyme inhibitory activity. The results of antibacterial assay revealed that the tested compounds showed good activity against Gram-positive bacteria, with 35 being the most potent with MIC 50 of 0.06 μg/mL against Staphylococcus aureus ATCC 25923. Molecular docking of 35 into S. aureus tyrosyl-tRNA synthetase active site was also performed. The inhibitor snugly fitting the active site may well explain its excellent inhibitory activity.

3-Aryltetronic acids: Efficient preparation and use as precursors for vulpinic acids

3-Aryltetronic acids were prepared in one step by treatment of a mixture of methyl arylacetates and methyl hydroxyacetates with potassium tert-butoxide, via tandem transesterification/Dieckmann condensation. Several mushroom or lichen pigments, vulpinic acids, were synthesized from 3-(4-methoxyphe-nyl) tetronic acid in three steps involving the reaction of the corresponding dianion with an α-ketoester and the dehydration of the tertiary alcohols obtained into mixtures of (E)-and (Z)-alkenes, which were converted under UV irradiation at 254 nm to natural (E)-isomers. Syntheses of pinastric acid, 4,4′-dimethoxyvulpinic acid, and the first synthesis of recently isolated methyl 3′,5′-dichloro-4,4′-di-0-methylatromentate were hence achieved in an efficient manner.
