Binding
Binding Assay: The assay below is used to test the modulatory activity of compounds against FLAP. Human and mouse FLAP-encoding DNA was amplified by polymerase chain reaction and cloned into pFastBac1 (Invitrogen) with a NH2-terminal 6-His tag for expression in Spodoptera frugiperda (Sf-9) cells. FLAP-containing membranes were prepared as was a FITC-labeled FLAP modulator (3-(3-(tert-butylthio)-1-(4-chlorobenzyl)-5-(quinolin-2-ylmethoxy)-1H-indol-2-yl)-2,2-dimethylpropanoic acid). The FLAP binding assay is performed in HTRF format (homogeneous time resolved fluorescence). FLAP-containing membranes (1 μg/well final for human) are incubated in the presence of the HTRF ligand, [5-[({[2-(2-{3-[3-(tert-butylsulfanyl)-1-(4-chlorobenzyl)-5-(quinolin-2-ylmethoxy)-1H-indol-2-yl]-2,2-dimethylpropanoyl}hydrazino)-2-oxoethyl]sulfanyl}acetyl)amino]-2-(6-hydroxy-3-oxo-3H-xanthen-9-yl)benzoic acid] (25 nM final), a terbium labeled anti-His tag antibody (0.5 ng/well final, from Cisbio) and compounds. The reaction is allowed to proceed for two hours after which the plate is read on an Envision plate reader in HTRF mode. Data are expressed as a HTRF ratio.For human FLAP binding assays, data are analyzed with 3DX Explorer software. A ratio is calculated with the relative light units at 520 nm over the relative light units at 495 nm. For analysis, data from multiple runs are averaged and each compound may be tested in 2 to 20 runs. Each run comprises two plates and each plate includes duplicates. Data from each plate is averaged and data are imported into 3DX. The data from multiple runs are aggregated as the average of duplicates of the calculated ratios in order to calculate Ki and IC50 values. The letters ND and/or the absence of data in any of the boxes in Table 5 and Table 6 indicates that Ki or IC50 values were not determined.
