Spectral binding results for clotrimazole with recombinantly expressed CYP26A1, CYP26B1 or CYP2C8, suggesting enzyme inhibition occurs through type II binding interactions with the heme. Ks,unb affinity constants for CYP26A1 (13.3 nM), CYP26B1 (24.7 nM) and CYP2C8 (75.5 nM) were determined through nonlinear regression analysis (inset figures) and corrected for nonspecific binding in the in vitro assays.
