|Description||Ciclopirox is a broad-spectrum antifungal agent working as an iron chelator.|
Ciclopirox olamine (CPX) is a lipophilic bidentate iron chelator that stabilizes HIF-1alpha under normoxic conditions at lower concentrations than other iron chelators, probably by inhibiting HIF-1alpha hydroxylation. Ciclopirox olamine (CPX)-induced HIF-1 mediates reporter gene activity and endogenous HIF-1 target gene expression, including elevation of transcription, mRNA, and protein levels of the vascular endothelial growth factor (VEGF). Ciclopirox inhibits growth of C. albicans yeast and hyphal cells in a dose-dependent manner.  Ciclopirox blocks H2O2-induced mitochondrial injury by maintaining mitochondrial transmembrane potential (Deltapsim). Ciclopirox completely blocks H2O2-stimulated release of lactate dehydrogenase (a marker of cell death) and decreases in MTT reduction (a marker of mitochondrial function) in adenocarcinoma SK-HEP-1 cells. Ciclopirox effectively inhibits H2O2-induced mitochondrial permeability transition pore (MPTP) opening.  Ciclopirox increases the MTP, maintained it high, and blocks the ATP depletion in glucose-deprived SIN-1-treated astrocytes. Ciclopirox protects astrocytes from peroxynitritecytotoxicity by attenuating peroxynitrite-induced mitochondrial dysfunction.  Ciclopirox is a substituted pyridone antimycotic drug, unrelated to the imidazole derivatives and its topical application ensures maximum local bioavailability. Ciclopirox acts on fungi by inhibiting the intracellular uptake of essential substrates and ions and this probably acts on the Candida ability to express its adherence mechanisms.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
