Description générale

Chemical structure: imidazole

Application

Clotrimazole has been used:
  • to study the upregulation of the gene ERG11 that codes for an azole target enzyme lanosterol demethylase, in Candida species, upon treatment with azole antibiotics
  • to study the development of resistance in Candida species isolated from patients undergoing prolonged antifungal treatment
  • to induce stress granules via mitochondrial stress
  • for the inhibition of in vitro formation of high density sickle cells induced by treatment with 1-chloro-2,4-dinitrobenzene (CDNB)
  • to inhibit cytochrome P450 enzyme in cell cultures

Actions biochimiques/physiologiques

Clotrimazole is a specific inhibitor of Ca2+-activated K+ channels. It is an antifungal azole. Clotrimazole is a derivative of imidazole and has similar antimicrobial action and activity to ketoconazole. It 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.
