Antifungal activity of some imidazole derivatives

Abstract

A series of 4(5)-arylimidazoles and their N-alkyl and other derivatives has been synthesised. Some of these compounds possessed good in vitro antifungal action, especially against strains of Trichophyton and less activity against Microsporum, Aspergillus and Candida strains; their activity against all mycological pathogens was reduced in the presence of serum. The three most active compounds are 1-alkyl-4-(3,4-dichlorophenyl)imidazoles in which the alkyl group is an n-propyl, n-butyl or isobutyl group. 4(5)-(2,3,4-Trichlorophenyl)imidazole is also almost as potent as an antifungal compound. Structure-antifungal activity relations for these compounds are discussed.
