Bifonazole ( Bifomyk; Bay H-4502; Bifokey;Bifon) is a potent imidazole-based antifungal drug with a broad-spectrum of antimycotic activity by interfering with sterol biosynthesis. Bifonazole has dual mode of action by blocking the transformation of 24-methylendihydrolanosterol to desmethylsterol in fungi together with inhibition of HMG-CoA. This enables fungicidal properties against dermatophytes and distinguishes bifonazole from other antifungal drugs. Bifonazole is a marketed drug developed by Bayer under the trade name of Canespor in ointment form.

Sterol biosynthesis is hampered by the new broad-spectrum antimycotic bifonazole (Bay H-4502). Bifonazole also directly inhibits HMG-CoA-reductase in dermatophytes. Bifonazole acts sequentially, inhibiting both direct inhibition of HMG-CoA-reductase and the cytochrome P450-dependent C14-demethylation of sterols. Bifonazole (Bay H-4502) exhibits a highly pH-dependent efficacy in vitro.Using various pathogens, the uptake kinetics of Bifonazole (Bay H-4502) have been measured[1]. In addition, compared to clotrimazole, bifonazole (Bay H-4502) generally causes a lower rate of sterol biosynthesis because it directly inhibits microsomal HMG-CoA-reductase. Bifonazole (Bay H-4502) is thought to have additional fungicidal effects that stem from sequential inhibition of cytochrome P450 and HMG-CoA-reductase. [2]. The choice of medium had an impact on bifonazole (Bay H-4502), with Kimmig's agar typically providing the lowest MICs. When tested on Kimmig's agar, it was found that the MICs of befonazole varied with pH (maximum activity at pH 6.5) with certain yeasts[3].

| Additional Infomation |
1-[biphenyl-4-yl(phenyl)methyl]imidazole is a member of the class of imidazoles carrying an alpha-(biphenyl-4-yl)benzyl substituent at position 1. It is a member of imidazoles and a member of biphenyls.
Bifonazole is an azole antifungal drug. Drug Indication Used for the treatment of various topical fungal infections, including athlete's foot (tinea pedis). Mechanism of Action Bifonazole works by inhibiting the production of a substance called ergosterol, which is an essential component of fungal cell membranes.It acts to destabilize the fungal cyctochrome p450 51 enzyme (also known as Lanosterol 14-alpha demethylase). This is vital in the cell membrance structure of the fungus. Its inhibition leads to cell lysis. The disruption in production of ergosterol disrupts the cell membrane and causes holes to appear. The cell membranes of fungi are vital for their survival. They keep unwanted substances from entering the cells and stop the contents of the cells from leaking out. As bifonazole causes holes to appear in the cell membranes, essential constituents of the fungal cells can leak out. This kills the fungi. Pharmacodynamics Bifonazole is a type of antifungal medicine known as an imidazole. It kills fungi and yeasts by interfering with their cell membranes. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
