| Description: | The DHODH activity assay is a coupled enzyme assay in which oxidation of DHO and subsequent reduction of ubiquinone are stoichiometrically equivalent to the reduction of DCIP (2,6-dichlorophenol). The reduction of DCIP is accompanied by a loss of absorbance at 610 nm.Reagents Used:L-Dihydroorotic acid, Sigma, D7128, 2,6-Dichloroindophenol sodium salt hydrate, sigma, D1878 Dimethyl sulfoxide (DMSO), spectroscopic grade purchased from Spectrochem, cat no. 0704209, B. no.--3183650 Decylubiquinone, Sigma, D7911Preparation of Solutions/Reagents:Buffer Preparation: 50 mM tris HCl, 150 mM KCl, and pH 8.0, 0.8% triton.L-Dihydroorotic acid stock solution of 20 mM in buffer2,6-Dichloroindophenol Sodium salt hydrate stock solution of 20 mM in bufferDecylubiquinone stock solution of 20 mM in bufferDMSO used as vehicleProcedure:5 .mu.L of Dimethyl sulfoxide or a compound of formula I in DMSO solution was added to the wells of a 96 well plate. Compounds of formula I were measured at 10 .mu.M. |
