Assay Method Information

Assay Name:  Inhibitory Assay
Description:  The compounds of the present invention obtained in the Production Examples were examined for the inhibitory effect on human monoamineoxydase enzymes (MAO-A and MAO-B) by the following method.Gene recombinant human MAO-A and MAO-B enzymes were purchased from Sigma Ltd. The human MAO-A and MAO-B activities were measured using MAO Detection Kit (Fluoro MAO, Cell Technology Inc.). Assay was performed in a 96-well plate. 1× Reaction buffer (40 μl) was added to each well, and 50 μl (5 mg/ml) of MAO-A or MAO-B was added. Then, test compound solutions (final concentration 1×10−4-1×10−10 mol/l) (10 μl) were added and the mixtures were incubated at 37° C. for 20 mins. Reaction cocktail (100 μl) was added, and the mixtures (final volume 200 μl) were incubated at 37° C. for 2 hrs. Thereafter, the fluorescence at 590 nm was detected with an excitation wavelength of 570 nm using a multispectro microplate reader (Varioskan, Thermo Fisher Scientific K.K.).
