Determination of 1-furan-2-yl-3-pyridin-2-yl-propenone, an anti-inflammatory propenone compound, by high performance liquid chromatography with ultraviolet spectrometry.

1-Furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) has recently been synthesized and characterized to have an anti-inflammatory activity. In the present study, pharmacokinetic parameters for FPP-3 and its metabolites were determined at the same time by using high-performance liquid chromatography-ultraviolet spectrometry. Two metabolites were detected in sera when FPP-3 was administered intravenously to male SD rats. The linearity of FPP-3, M1 (1-furan-2-yl-3-pyridin-2-yl-propan-1-one) and M2 (1-furan-2-yl-3-pyridin-2-yl-propan-1-ol) was confirmed in the concentration ranges of 0.5-20, 0.101-4.04 and 1.04-20.4 microg/ml, respectively. The lower limits of quantitation of FPP-3, M1 and M2 were 0.5, 0.1 and 1.0 microg/ml, respectively. The intra- and inter-day precision and accuracy over the concentration range of target compounds were within 13.5 and 14.2%, respectively. The half-lives of FPP-3, M1 and M2 were 16.3, 27.7 and 22.1 min, respectively.
