| Description: | To confirm whether the compounds according to the present disclosure have an effect of inhibiting 15-PGDH, the NADH, which appears at the wavelength of 340 nm, of Compounds 1 to 105 purified in (1) nm was measured by using fluorescence spectra photometer. That is, the cells were treated with a solution including 50 mM Tris-HCl (pH 7.5), 0.1 mM DTT, 0.25 mM (NAD+), 10 μg of purified 15-PGDH enzyme, 21 μM PGE2. and various concentrations (0.0001 μM to 64 μM) of the derivative compound according to the present disclosure. In this case, the total volume of the solution was 2 ml. Then, the absorbance of the reaction mixture was recorded at the wavelength of 340 nm. To measure the activity of the derivative compounds according to the present disclosure, which is an inhibitor of 15-PGDH, the average value of NADH absorbance at 340 nm at various concentrations was obtained from a standard curve. The results of the 15-PGDH inhibitory activity of the derivative compounds according to the present disclosure are shown in Tables 1 and 2 below. In Tables 1 and 2, IC50 indicates a concentration at which the compound according to the present disclosure inhibits 50% of 15-PGDH activity. |
