Application

4-Phenylimidazole was used to investigate the protein-ligand interactions in cytochrome P450 from the thermoacidophile Picrophilus torridus. It was used as heme ligand during the crystallization of recombinant human indoleamine 2,3-dioxygenase. It was used in the synthesis of complexes of copper and cobalt.

The molecular basis for reversible inhibition of rabbit CYP2B4 and CYP2B5 and rat CYP2B1 by phenylimidazoles was assessed with active-site mutants and new three-dimensional models based on the crystal structure of CYP2C5. 4-Phenylimidazole was 17- to 32-fold more potent toward

Series of 4-arylimidazoles, omega-N-acylhistamines and 4-(omega-phenylalkyl)imidazoles were synthesized in order to probe the active site topology of sweet almond beta-glucosidase. These imidazole derivatives were shown to be very powerful competitive inhibitors. Among the 20 tested compounds, omega-N-benzoylhistamine and 4-(3'-phenylpropyl)imidazole are

The molecular origins of temperature-dependent ligand-binding affinities and ligand-induced heme spin state conversion have been investigated using free energy analysis and DFT calculations for substrates and inhibitors of cytochrome P450 2B4 (CYP2B4), employing models of CYP2B4 based on CYP2C5(3LVdH)/CYP2C9 crystal
