CHMFL-BMX-078 (CHMFL-BMX 078)

Kinase experiment:

The kinase reaction system contains BMX or BTK, 1 μL of serially diluted CHMFL-BMX-078, and substrate Poly peptidewith 100 μM ATP. The reaction in each tube is started immediately by adding ATP and kept going for an hour under 37 °C. After the tube cooled for 5 min at room temperature, 5 μL solvent reactions are carried out in a 384-well plate. Then 5 μL of ADP-Glo reagent is added into each well to stop the reaction and consume the remaining ATP within 40 min. At the end, 10 μL of kinase detection reagent is added into the well and incubated for 30 min to produce a luminescence signal. Luminescence signal is measured with an automated plate reader[1].

Animal experiment:

Rats: Six 8-week-old male Sprague−Dawley rats are fasted overnight before starting drug treatment via intravenous and oral administration. Animal blood collection time points are as follows. For groups 1, 3, and 5 (intravenous): 1 min, 5 min, 15 min, 30 min, 1 h, 2 h, 4 h, 6 h, and 8 h before and after administration is selected. For group 2, 4, and 6 (oral): 5 min, 15 min, 30 min, 1 h, 2 h, 4 h, 6 h, 8 h, and 24 h before and after dosing. The plasma is collected for analysis[1].
