Ketoconazole CAS#65277-42-1
      
                - Broad-Spectrum Antifungal Action: Ketoconazole effectively treats both superficial and systemic fungal infections by inhibiting fungal cytochrome P-450, disrupting ergosterol synthesis in cell membranes. 
- Prevents Fungal Growth and Spore Formation: It halts fungal infection by inhibiting growth and preventing spores from turning into mycelium, stopping further spread of infection. 
- Bacterial Inhibition: At low concentrations, ketoconazole inhibits bacterial growth, while at high concentrations, it can kill bacteria, broadening its antimicrobial effectiveness. 
- Wide Clinical Use: Ketoconazole is effective against various fungi (e.g., Candida, Histoplasma) and is used to treat conditions like tinea and skin candidiasis. 
Ketoconazole is a broad-spectrum imidazole antifungal drug, sold under the brand names Jindaconin, Mikangling, and Kening. It selectively inhibits fungal cytochrome P-450, disrupting ergosterol synthesis in cell membranes. This makes it effective against both superficial and systemic fungal infections. Ketoconazole not only inhibits fungal growth but also prevents spores from turning into mycelium, halting further infection.
At low concentrations, it inhibits bacteria, while at high concentrations, it kills them. It is effective against Candida, Coccidioides, Histoplasma, Sporothrix, and Trichophyton. Clinically, it treats conditions like tinea manuum, tinea pedis, tinea corporis, tinea cruris, thrush, and skin candidiasis.
