Bunaprolast (U-66,858) undergoes deacetylation to an initial metabolite with similar pharmacological potency. The inhibitory effects of the semi-quinone Bunaprolast and its metabolite U-68,244 on the ionophore-induced formation of leukotriene B4 (LTB4) are examined in human whole blood (WB). Preincubation of Bunaprolast and U-68,244 for 1 min prior to challenge of blood with calcium ionophore A23187 results in IC50s of 1080±644 and 820±442 nM, respectively. After 60 min preincubation, IC50s are 250±85 and 270±79 nM. The activity of the lipoxygenase inhibitor AA-861 in this system is similar to that of Bunaprolast, while vitamin K and the sulphate conjugate of Bunaprolast show significant inhibition of LTB4 release only at micromolar concentrations. Bunaprolast exhibits significant inhibition of thromboxane A2 release (p<0.02) in a comparative study with the known cyclooxygenase (CO) inhibitor Flurbiprofen[1].
