Description
Metabolism test using human liver lysosomal fraction. To a reaction composition solution in which human liver lysosome (corresponding to 0.125 mg of protein) was suspended and distilled water (10 uL) was added 1.2 uM test compound (25 uL) dissolved in PBS to prepare a reaction solution. After the reaction solution was incubated at 37 °C for 24 hours, U-036 released from the Example A9 into the reaction solution was quantified by LC-MS/MS.

Description
Metabolism test using human liver Cathepsin B. To human liver Cathepsin B (corresponding to 400 Unit/mL) (5 pL), X10 Catabolic Buffer (10 uL), 2.5 mM Bovine Serum Albumin (5 uL), and distilled water (55 uL) was added 1.2 uM test compound (25 uL) dissolved in PBS to prepare a reaction solution. After the reaction solution was incubated at 37°C for 24 hours, U-036 released from the Example A9 into the reaction solution was quantified by LC-MS/MS.
