title: Novel high energy intermediate analogues with triazasterol-related structures as inhibitors of ergosterol biosynthesis. Part I: synthesis and antifungal activity of N-alkyl-N'-(phenethyl- and cyclohexenylethyl)guanidines and N2-substituted 2-imidazolinamines.
abstract: A series of N-alkyl-N'-(phenethyl- and cyclohexenylethyl) guanidines and N(2)- and N(2), 4-substituted imidazolin-2-amine hydrochlorides with triazasterol-related structures was designed and synthesized as stable analogues to mimic high energy intermediates of ergosterol biosynthesis. The in vitro antifungal susceptibility tests with a standard panel of pathogenic fungi revealed moderate to strong antimycotic effects of the sixteen prepared compounds, in some cases comparable with the activity observed for itraconazole.
