ChEMBL	Cellular Inhibition Assay: V79MZ cells expressing human CYP11B1 and human CYP11B2 genes, respectively, were grown on 24-well cell culture plates (8×10^5 cells per well) with 1.9 cm^2 culture area per well in 1 ml DMEM culture medium until confluence. Before testing, the DMEM culture medium was removed and 450 μl of fresh DMEM, containing the inhibitor in at least three different concentrations for determining the IC50 value, was added to each well. Every value was determined at least three times. After a pre-incubation step of 60 min at 37° C., the reaction was started by the addition of 50 μl of DMEM containing the substrate 11-deoxycorticosterone (containing 0.15 μCi of [1,2-3H] 11-deoxycorticosterone, dissolved in ethanol, final concentration 100 nM). The V79MZh11B1 cells were incubated for 25 min, the V79MZh11B2 cells were incubated for 50 min. Controls were treated in the same way without inhibitors. The maximum DMSO concentration in each well was 1%. Enzyme reactions were stopped by extracting the supernatant with 500 μl ethyl acetate. Samples were centrifuged (10000×g, 2 min), and the solvent was pipetted into fresh cups. The solvent was evaporated and the steroids were redissolved in 40 μl of methanol and analyzed by HPLC using radioflow detection (Ehmer et al. J. Steroid Biochem. Mol. Biol. 2002, 81, 173-179 and Denner et al. Endocr. Res. 1995, 21, 443-448).	B	7.82	pIC50	15	nM	IC50	US-9394290-B2. Selective CYP11B1 inhibitors for the treatment of cortisol dependent diseases (2016)

ChEMBL	null: A commercially available P450-GLO Assay kit (Promega Corporation, Madison Wis.) is used to screen various compounds for CYP3A4A inhibition activity. CYP3A4A is thought to be one of the primary CYP isoforms responsible for retinoic acid metabolism in the skin. Three benchmark agents, liarozole, climbazole, and ketoconazole, were assessed for CYP3A4 inhibition to confirm that the inhibition activity (the IC50 for CYP3A4 inhibition) measured by the assay corresponds to the activity reported by the published literature. The results show that the substituted azole compounds having the specific structure set forth herein are CYP inhibitors, and thus function as RAMBAs.	B	5.52	pIC50	3000	nM	IC50	US-9138393-B2.

ChEMBL	In vitro CYP3A4 Inhibition Assay: Cytochrome P450 is a large and diverse group of enzymes that catalyze the oxidation of organic substances. Some members of the CYP family contribute to the elimination of ATRA by catalyzing its 4-hydroxylation in the mammalian liver and skin, including that of humans as well as swine. Applicant evaluated the potential RAMBA activity of several azoles using pig liver microsomes, a rich source of CYP activity, comprising many different CYP 450 isoforms. Therefore, this approach, while a reasonable way to assess CYP inhibitors with broad activities may or may not be the best way to discover RAMBAs with selectivity for the skin, which has a much more narrow complement of CYP expression. As understanding in this area has progressed, a more specific CYP inhibition assay can be used to provide better predictivity of activity in human skin. Nevertheless, this assay may still be used as a general predictor of overall CYP activity.	B	5.52	pIC50	3000	nM	IC50	US-9144538-B2.
