Miconazole Nitrate is the nitrate salt of Miconazole, an imidazole antimycotic compound patented in 1968 (Janssen Pharmaceutica). It targets the fungi that cause tinea (ringworm) and athlete’s foot. It inhibits ergosterol synthesis, and a variety of cytochrome P450 enzymes, and can be used for cytochrome P450 profiling. The compound can act as a chemopreventive agent in a mammary cancer cell model. Miconazole nitrate is sparingly soluble in DMSO and DMF and very slightly soluble in ethanol.

- Miconazole (M041)
|Mechanism of Action||
Miconazole Nitrate increases cell permeability by inhibiting enzymes involved in ergosterol synthesis, including a variety of cytochrome P450 enzymes including cytochrome P450-dependent 14-alpha-demethylase. The increase of permeability has a toxic effect on the fungi and leads to cell death. Miconazole can also act as an antagonist of the glucocorticoid receptor (GR) and can inhibit aromatase.
|Spectrum||Miconazole Nitrate has activity against fungi including Candida, Trichophyton species. Trichophyton causes tinea (ringworm).|
Miconazole is commonly used in clinical in vitro microbiological antimicrobial susceptibility tests (panels, discs, and MIC strips) against fungal isolates. Medical microbiologists use AST results to recommend antibiotic treatment options. Representative MIC values include:
