DETAILS

Specific inhibitor of Ca^2+ activated K^+ channels.

DrugBank - DB00257

• Drug Groups: approved
• Description: An imidazole derivative with a broad spectrum of antimycotic activity. It inhibits biosynthesis of the sterol ergostol, an important component of fungal cell membranes. Its action leads to increased membrane permeability and apparent disruption of enzyme systems bound to the membrane. [PubChem]
• Indication: For the local treatment of oropharyngeal candidiasis and vaginal yeast infections, also used in fungal infections of the skin such as ringworm, athlete's foot, and jock itch.
• Pharmacology: Clotrimazole, an imidazole derivative with a broad spectrum of antimycotic activity, inhibits biosynthesis of the sterol ergostol, an important component of fungal cell membranes. Its action leads to increased membrane permeability and apparent disruption of enzyme systems bound to the membrane. Betamethasone and clotrimazole are used together to treat cutaneous tinea infections. In studies in fungal cultures, the minimum fungicidal concentration of clotrimazole caused leakage of intracellular phosphorous compounds into the ambient medium with concomitant breakdown of cellular nucleic acids, and accelerated potassium etflux. Both of these events began rapidly and extensively after addition of the drug to the cultures. The primary action of clotrimazole is against dividing and growing organisms.
• Toxicity: Symptoms of overdose include erythema, stinging, blistering, peeling, edema, pruritus, urticaria, burning, and general irritation of the skin, and cramps.
• Affected Organisms: Yeast and other fungi
• Biotransformation: Hepatic (metabolized to inactive metabolites)
• Absorption: Poorly and erratically absorbed orally, minimal vaginal or topical absorption.
• Half Life: 2 hours
• Protein Binding: 90%

Selleck Chemicals - S1606

Research Area: Infection
Biological Activity:
Clotrimazole(Canesten) is a synthetic, antifungal and broad-spectrum derivate of imidazole. Clotrimazole inhibits biosynthesis of sterols, particularly inhibiting ergosterol, which is an essential component of the fungal cell membrane, thereby damaging and affecting the permeability of the cell membrane. This results in the  leakage and the loss of essential intracellular compounds, and eventually causes the lysis of cell.  [1, 2]

Sigma Aldrich - C6019

Biochem/physiol Actions
Specific inhibitor of Ca2+-activated K+ channels. Antifungal azole. Antifungal mode of action: Inhibits cytochrome P450-dependent 14α-demethylase, which is critical to ergosterol biosynthesis. The accumulated 14α-methylated sterols change the membrane structure of sensitive fungi, altering cell membrane permeability.
