ChEMBL	Fluorescent High Throughput P450 Assay: The interaction of SC12 with cytochrome P450 enzymes was tested using Fluorescent High Throughput P450 assays (Gentest); The IC50s of the compounds was calculated on isoenzymes (CYP1A2, CYP2C9, CYP2C19, CYP2C8, CYP2B6, CYP2D6, CYP2E1, CYP3A4 and CYP3A5). Inhibition of the P450 isoforms was measured in specific assays using specific substrates that become fluorescent upon CYP metabolism. Compounds, dissolved in ACN (acetonitrile) (CYP2E1, CYP2C8, CYP2B6, CYP3A5) or DMSO (all remaining isoforms), were tested in duplicate (n=2) in concentration-response curves (eight concentrations) in a 96-well plate containing incubation/NADPH regenerating buffer. Specific isoenzymes and substrates were added and incubated at 37° C. Reactions were terminated at different times, depending on the assays, and plates read on a Fluoroskan Ascent at the appropriate emission/excitation wavelengths. Concentration-response curves performed in duplicate for known inhibitors for each isoenzyme were tested in ever	B	6.57	pIC50	270	nM	IC50	US-9173935-B2. Phospholipid drug analogs (2015)
