Description
DMU2139 is a potent and specific CYP1B1 inhibitor, with IC 50 s of 9 nM and 795 nM for CYP1B1 and CYP1A1, respectively.In VitroDMU2139 (6j) shows 88 and 133-fold selectivity for CYP1B1 over CYP1A1 and CYP1A2. In the presence of DMU2139, the EC 50 is reversed back to 8.3 µM from 61 µM (seen in CYP1B1-expressing cells without any inhibitor). The EC 50 value, in the presence of DMU2139, resembles the EC 50 of cisplatin, 8.7µM, in cells transfected with the empty plasmid which has no CYP1B1 gene and therefore cannot express CYP1B1 protein. MCE has not independently confirmed the accuracy of these methods. They are for reference only.IC50& Target:CYP1B1 9 nM (IC 50 ) CYP1A1 795 nM (IC 50 )
