The Journal of Organic Chemistry , 79 22 , Pedro Laborda, Francisco J. Organic Letters , 16 5 , Synthetic imidazoles are present in many fungicides and antifungal , antiprotozoal , and antihypertensive medications. Imidazole is part of the theophylline molecule, found in tea leaves and coffee beans, that stimulates the central nervous system. It is present in the anticancer medication mercaptopurine , which combats leukemia by interfering with DNA activities.
A number of substituted imidazoles, including clotrimazole , are selective inhibitors of nitric oxide synthase , which makes them interesting drug targets in inflammation , neurodegenerative diseases and tumors of the nervous system. For comparison, another group of azoles is the triazoles, which includes fluconazole , itraconazole , and voriconazole. The difference between the imidazoles and the triazoles involves the mechanism of inhibition of the cytochrome P enzyme.
The N3 of the imidazole compound binds to the heme iron atom of ferric cytochrome P, whereas the N4 of the triazoles bind to the heme group. The triazoles have been shown to have a higher specificity for the cytochrome P than imidazoles, thereby making them more potent than the imidazoles. It is instead a precursor to a variety of agrichemicals, including enilconazole , climbazole , clotrimazole , prochloraz , and bifonazole.
