Variable benzo[b]furan derivatives having (E)- and (Z)-2-alkylcarbamoyl-1-methylvinyl groups at the 2-, 4- and 5-positions and a carboxylpropoxy or (1-phenyl)ethoxy group at the 7-position were prepared to find novel and selective leukotriene B4(LTB4) receptor antagonists. (E)-2-(2-diethylcarbamoyl-1-methylvinyl)-7-(1-phenylethoxy)benzo[b]furan (4v) showed selective inhibition to the human BLT2...

Furan-cored AIEgen namely tetraphenylethylene-furan (TPE-F) is developed by diyne cyclization and its fluorescent and chemical properties are investigated and compared with its thiophene analogue. Results show that furan is superior to thiophene in terms of fluorescence, chromism, and charge transport. The mechanism of chromism of TPE-F is investigated and its efficient solid-state photolumines...

In this work, we evaluated the occurrence of furan in brews obtained from regular, decaffeinated, and instant coffee and commercial packed capsules. For this purpose, a previously developed automated headspace solid-phase microextraction method coupled to gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used. Initially, the influence of HS-SPME conditions on furan formation was evaluate...

Furan is a liver carcinogen and toxicant. Furan is oxidized to the reactive dialdehyde, cis-2-butene-1,4-dial, by microsomal enzymes. This reactive metabolite readily reacts with glutathione nonenzymatically to form conjugates. A high-performance liquid chromatography-electrochemical method for the detection of cis-2-butene-1,4-dial-glutathione (GSH) conjugates in microsomal preparations was de...

We assessed the effects of furan and lycopene on the histopathological and biochemical changes on lungs, body and lung weights, and food consumption of rats. Furan and diabetes caused histopathological changes, increment in malondialdehyde levels, and decrease in antioxidant enzyme activities. Lycopene showed a protective effect against these damages, except for glutathione-S-transferase and gl...

Singlet Oxygen, Pyrene, Diphenylisobenzofuran, Micelles The reaction of singlet oxygen with 1,3-diphenylisobenzofuran was investigated in aqueous micellar solutions of sodium dodecyl sulfate and dodecyl trimethylammonium chloride using pyrene as photosensitizer. Singlet oxygen, produced by the photosensitization of pyrene bound to micelles, oxidized efficiently 1,3-diphenylisobenzofuran bound t...

Furan is a liver toxicant and carcinogen in rodents. It is classified as a possible human carcinogen, but the human health effects of furan exposure remain unknown. The oxidation of furan by cytochrome P450 (P450) enzymes is necessary for furan toxicity. The product of this reaction is the reactive α,β-unsaturated dialdehyde, cis-2-butene-1,4-dial (BDA). To determine whether human liver microso...

The aim of this work was to assess the damage of DNA in human blood cell and sperm in vitro under the influence of furan. These cells were administered 0-600 μM of furan at 37 and 32 o C for 30 and 60 min, respectively. A significant increase in tail DNA%, tail length and moment indicating DNA damage was observed at increasing doses when compared to the controls. The treatment with 300 and 600 ...

Thiophene-linked π-conjugate shows better solvatochromic redshift and AIE-features than furan-analog. Yet, furan-linked is a solid-state emitter with reversible mechanofluorochromic features. Variations in crystal packing play crucial role this disparity.

In the title compound, C(19)H(13)BrO(3)S, the 4-bromo-phenyl ring makes a dihedral angle of 64.11 (2)° with the mean plane [r.m.s. deviation = 0.01 (2) Å] of the naphtho-furan ring. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits slipped π-π inter-actions between the central naphtho-furan benzene rings of neighbouring mol-ecules [...
