The rat/human hepatocyte metabolic stability analysis protocol was used to determine the clearance rate of the compound of the present invention in vitro.
Male rat hepatocytes and mixed sex human hepatocytes were obtained from commercial suppliers (eg BioreclamationIVT) and stored at -150°C before use. Prepare a 10 mM stock solution of the test compound in DMSO. Place the thawed medium and supplemented incubation medium (without serum) in a 37°C water bath for at least 15 minutes before use. The stock solution was diluted to 100 μM by combining 198 μL of acetonitrile and 2 μL of 10 mM stock solution.
Remove the vial of cryopreserved hepatocytes from storage and ensure that the vial is kept at a low temperature. The vial was thawed in a 37°C water bath with gentle shaking. Keep the vial in a water bath until all ice crystals are dissolved and no longer visible. Spray the vial with 70% ethanol and then transfer it to a biosafety cabinet. Then pour the contents into a 50 mL thawing medium conical tube. The vial was centrifuged at 100 g for 10 minutes at room temperature. Aspirate the thawing medium and resuspend the hepatocytes in serum-free culture medium to obtain about 1.5×106

Live cells/ml of hepatocytes were boiled for 10 minutes and then added to the plate as a negative control, which eliminated enzyme activity so that only minimal or no substrate conversion could be observed. Negative samples are prepared using inactivated liver cells, which are used to exclude misleading factors caused by the instability of the chemical substance itself.
An aliquot of 247.5 μL of hepatocytes was dispensed into each well of a 96-well uncoated plate. Place the plate in an incubator on an orbital shaker for approximately 10 minutes. An aliquot of 2.5 μL of 100 μM test compound was added to the corresponding well of the uncoated 96-well plate to start the reaction. Two repeated experiments were performed for this analysis. Place the plate on the orbital oscillator in the incubator for incubation for the design time point. At 5, 15, 30, 45, 60, 80, and 100 minutes time points, 20 μL of content was transferred and mixed with 6 volumes (120 μL) of cold acetonitrile containing internal standard to terminate the reaction.
