| | Measurement of JNK3 Enzyme Activity |
| Description: | First of all, after a substrate was inserted into a prepared base reaction buffer solution (20 mM Hepes (pH 75), 10 mM MgCl2, 1 mM EGTA, 0.02% Brij35, 0.02 mg/ml BSA, 0.1 mM Na3VO4, 2 mM DTT, 1% DMSO), a human JNK3 enzyme was added into a prepared substrate solution and then mixed together. As the substrate, ATP (10 μM) and ATF2 (3 μM) were used, among which the ATP was also used as a common substrate. Then, compounds of Examples 1-18 and 25-36, which were dissolved in 100% DMSO, were inserted into an enzyme reaction solution, and then cultured at room temperature for 20 minutes. Then, 33P-ATP was inserted into the above reaction mixture solution to initiate a reaction, then cultured at room temperature for 2 hours, and then an enzyme activity was detected by means of a filter-binding method.Particularly, after each 25 μl of the resulting solution was slowly spotted on P81 paper, it was inserted into a scintillation vial, and washed with 0.75% phosphoric acid four times for 10 minutes each, and with acetone once for 5 minutes. 5 ml of scintillation cocktail was inserted into the above scintillation vial and a resulting signal was read by means of a scintillation counter. |
