| | Inhibition of JAK |
| Description: | The study of the effect of compounds on the activity of purified recombinant JAK was performed by studying the inhibitory activity of the compounds on JAK from the enzymatic level. The experimental principle is to use a luminescence kinase assay to detect the ADP content produced by the reaction of JAK with the substrate Poly (4:1 Glu, Tyr) peptide: after ADP is converted to ATP, ATP can act as a substrate for the Ultra-Glo luciferase catalytic reaction, producing an optical signal. The luminescence signal is positively correlated with the amount of ADP and kinase activity. Therefore, the inhibitory effect of the compounds on the recombinant JAK was determined by observing the luminescence signal produced by the reaction of JAK and the substrate, and was expressed by IC50. |
