ABSTRACT
Various aryl-(1H-imidazol-1-yl)-(isoquinolin-1-yl)methane derivatives have been synthesized and tested as antifungal agents. The new imidazoles have been obtained by the action of 1,1'-sulfinyldiimidazole on aryl-(isoquinolin-1-yl)carbinols, which have been prepared by standard procedures starting from isoquinoline. Among 44 test derivatives only a few have exhibited some antifungal activity, the most active compound (4e) being twofold less potent than miconazole, ketoconazole and bifonazole, used as standard drugs.

Various bipyrryl analogues of bifonazole were synthesized starting from aryl-3-pyrryl-1-imidazolylmethanes. The introduction of a second pyrryl portion was performed by linking an acrylate moiety at 1-position of the pyrrole ring and then by treatment with TosMIC. The bipyrryl esters were hydrolyzed and decarboxylated to afford the required imidazoles. All new imidazole derivatives were tested against Candida albicans and Candida spp using as standard controls miconazole, bifonazole and ketoconazole.
