| Description: | Cyp11 assay protocol: AD293 cells that stably over-express recombinant CYP-11 were seeded in 96 well plates coated with poly D-lysine (15,000 cell per well) and incubated at 37° C. for 24 hours in Dulbecco's Modified Eagle Medium (DMEM) with Fetal Bovine Serum (FBS) that is stripped of hormones by charcoal treatment. The media is then removed, the cells are washed once with Phosphate buffer saline solution, and 50 μL Dulbecco's Modified Eagle Medium (DMEM) with Fetal Bovine Serum (FBS) that is stripped of hormones by charcoal treatment is added. Compounds of the disclosure are then added to the wells in eight concentration spanning 10 μM to 4.5 nM, and the plates are incubated for an additional 60 minutes at 37° C. 11-deoxycortisol is then added (2.0 μM) and the plates are incubated for an additional 12 hours at 37° C. After incubation, 50 uL of the supernatant (medium) is transferred into a fresh plate and 150 uL of an acetonitrile solution containing 200 ng/ml of Telmisartan is added. The sample is mixed and then placed in a centrifuge at 2000 rpm for 5 minutes. 100 uL of the supernatant is transferred into a fresh 96 well deep well plate, 100 uL of 1:1 methanol: water was added, the solution was mixed and then analyzed by LC/MS for the presence of cortisol using an Agilent 1200 RRLC/ABSCIEX API4000 LC-MS or Shimadzu Prominance/ABSCIEX API4000 LC-MS to determine IC50s of the compounds of the disclosure. |
