| | hDPP7 Inhibition Assay |
| Description: | Table 4: Compounds were tested in a biochemical inhibition assay using human dipeptidylpeptidase 7 (hDPP7) enzyme (BPS Bioscience, #80070) and the substrate Ala-Pro-amino-methylcoumarin (BPS Bioscience, #80305) at 10 μM FAC. The enzymatic reactions were conducted in duplicate at rt for 20 min in 50 μL assay buffer (10 mM Tris-HCl, pH 7.4, 10 mM MgCl2, 1 mM MnCl2). Compound solutions (in DMSO) at 10 CR, 3-fold dilution series were prepared in assay buffer ten-fold higher than the final concentration, and 5 μL of the dilution was added to a 50 μL reaction so that the highest compound concentration was 10 μM FAC and the concentration of DMSO was 1% in all wells. The plates were read on a PHERAstarPLUS (BMG) using kinetic mode with excitation 340 nm and emission 460 nm. Data were analyzed in Graph Pad Prism. Raw data signals were normalized using 1% DMSO as 0% control and no enzyme as 100% inhibitor control. |
