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.

In our continuing search to find systemically bioavailable ACAT (acyl-CoA:cholesterol O-acyltransferase) inhibitors with more potent antiatherosclerotic effect than N-[2-(dimethylamino)-6-[3-(5-methyl-4-phenyl-1H-imidazol-1-yl)propoxy] phenyl]-N'-pentylurea (3), a series of phenylureas linked to 4-phenylimidazole were synthesized and evaluated for in vitro inhibitory activity toward both aortic

The crystal structure of a cytochrome P450 from the thermoacidophile Picrophilus torridus, CYP231A2 (PTO1399), has been solved. This structure reveals a wide open substrate access channel. To better understand ligand-induced structural transitions in CYP231A2, protein-ligand interactions were investigated using 4-phenylimidazole.

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

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
