      Bifonazole is an imidazole antifungal drug.;Target: AntifungalBifonazole, a new broad-spectrum antimycotic, interferes with sterol biosynthesis. In dermatophytes bifonazole additionally inhibits directly HMG-CoA-reductase. bifonazole possesses a sequential mode of action, namely inhibition of cytochrome P450-dependent C14-demethylation of sterols and direct inhibition of HMG-CoA-reductase. In vitro bifonazole shows a strongly pH-dependent efficacy. The uptake kinetics of bifonazole have been measured with different pathogens [1]. Bifonazole additionally leads to a generally decreased rate of sterol biosynthesis as compared to clotrimazole, due to a direct inhibition of microsomal HMG-CoA-reductase. The additional fungicidal effects of bifonazole are considered to originate from a sequential action by inhibition of HMG-CoA-reductase and of cytochrome P450 [2]. bifonazole were affected by choice of medium with Kimmig's agar generally giving the lowest MIC's.
