| Description: |
ABX-1431 is a highly potent, selective, and orally available, CNS-penetrant monoacylglycerol lipase (MAGL) inhibitor with an IC50 of 14 nM. |
| Target: |
IC50: 14 nM (human MGLL)[1] |
| In Vivo: |
ABX-1431 inhibits MGLL activity in rodent brain (ED50=0.5-1.4 mg/kg), increases brain 2-AG concentrations, and suppresses pain behavior in the rat formalin pain model[1]. |
| In Vitro: |
ABX-1431 is a potent human MGLL inhibitor (IC50=0.014 µM) with >100-fold selectivity against ABHD6 and >200-fold selectivity against PLA2G7. ABX-1431 inhibits human PC3 cells with an IC50 of 0.0022 µM. In the cell-based assay, >100-fold selectivity for MGLL over ABHD6 (IC50=0.253 µM) and PLA2G7 (IC50=494 µM) is maintained[1]. |
| Cell Assay: |
Human prostate cancer PC3 cells are grown in F-12K medium supplemented with 10% fetal bovine serum at 37°C with 5% CO2 to 80% confluency in 100 mm dishes. ABX-1431 is added to cells to give final concentration of 0.1-10 µM compound in serum free media. Cells are incubated for 30 min. Cells are washed, harvested, and lysed by probe sonication. Cell lysates (2mg/mL) are treated with JW912 (1µM) and analyzed by SDS-PAGE and in-gel fluorescence scanning[1]. |
| Animal Administration: |
Rats[1] ABX-1431 is administered in a volume of 5 mL/kg. Male ICR mice or male Sprague Dawley rats 6 to 12 weeks are administered single oral doses of ABX-1431 (0.5-32 mg/kg for mice and 0.03-10 mg/kg for rats). Four hours after ABX-1431 administration, animals are anesthetized. Following blood collection, animals are killed by decapitation and brains are removed, hemisected and frozen in liquid nitrogen for analysis[1]. |
