General description

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

Biochem/physiol Actions

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.

Stress granules (SGs) are cytoplasmic aggregates of stalled translational preinitiation complexes that accumulate during stress. GW bodies/processing bodies (PBs) are distinct cytoplasmic sites of mRNA degradation. In this study, we show that SGs and PBs are spatially, compositionally, and functionally

Clotrimazole, a specific inhibitor of the Ca(2+) activated potassium (Gardos) channel, and the antioxidant N-acetylcysteine were found to inhibit the in vitro formation of high-density sickle cells induced by treatment with 1-chloro-2,4-dinitrobenzene (CDNB). The CDNB induced leakage of K(+) can

Infections due to Candida albicans are usually treated with azole antifungals such as fluconazole, but treatment failure is not uncommon especially in immunocompromised individuals. Relatedly, in vitro studies demonstrate that azoles are nonfungicidal, with continued growth at strain-dependent rates even
