1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) is an anti-inflammatory agent with a propenone moiety. Following a single intravenous injection of male Sprague-Dawley rats with 4 mg/kg of FPP-3, three different metabolites of FPP-3 were identified as M1 (1-furan-2-yl-3-pyridin-2-yl-propan-1-one), M2 (1-furan-2-yl-3-pyridin-2-yl-propan-1-ol) and M3 (a glucuronide conjugate of M2) in rat urine by a liquid chromatography-electrospray tandem mass spectrometry. The structures of M1 and M2 were the same as observed previously following the incubation of rat liver microsomes with FPP-3 in the presence of NADPH. Although all metabolites of FPP-3 were identified in rat urine, only M1 and M2 were observed in the bile and feces. In addition, FPP-3 and its metabolites were mostly excreted into the urine. The M3 was identified as a glucuronide conjugate of M2 because of the addition of 176 Da from the protonated molecular ion of M2 in MS(2) and because of the production of free M2 following an incubation of urine with beta-glucuronidase. From these studies, a possible metabolic fate of FPP-3 could be proposed in vivo.

Carbonyl reduction is a significant step in the phase I biotransformation of a great variety of aromatic, alicyclic and aliphatic carbonyl compounds. 1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) has been shown to have anti-inflammatory activity as it inhibits the production of nitric oxide and tumor necrosis factor-beta. In the present study, the metabolic fate and possible involvement of 11beta-hydroxysteroid dehydrogenase (11beta-HSD) and carbonyl reductase (CBR) in the metabolism of FPP-3 were investigated in rat liver subcellular fractions.

Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) is a novel synthetic compound and has demonstrated anti-inflammatory activity by inhibiting cyclooxygenase-2 (COX-2). It is widely accepted that reactive oxygen species (ROS) generated by activated inflammatory cells can exacerbate inflammation. In this study, the potential antioxidative efficacy of FPP-3 has been investigated in murine cells.

1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) is an anti-inflammatory agent with a propenone moiety and chemically synthesized recently. In this study, we examined the chemopreventive effect of FPP-3 on 7,12-dimethylbenz[a]anthracene (DMBA)-induced genotoxicity in MCF-7 cells. FPP-3 reduced the formation of the DMBA-DNA adduct.

1-Furan-2-yl-3-pyridine-2-yl-propenone (FPP-3) is an investigatory drug which has a dual inhibitory action on cyclooxygenase (COX) and 5-lipoxygenase (5-LOX). We examined its effect on the pharmacokinetics of warfarin. Three consecutive days of pretreatment with 17 mg/kg of FPP-3 had no significant effect on the pharmacokinetic parameters of warfarin when orally administered to rats.
