Ethanol 30 mg/mL (111.79 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 40 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to make it clear; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Ciclopirox ethanolamine (Ciclopirox olamine, HOE 296,Ciclopiroxolamine) is a broad-spectrum antifungal agent working as an iron chelator.
Targets
ATPase [3]
In vitro

Ciclopirox significantly inhibits the growth of C. albicans strain SC5314 cells, with MIC80s of 1.0-2.0 μg/mL, growth decreased dramatically at the concentrations of >0.6 μg/mL, and almost complete growth inhibition at concentration of 0.7 μg/mL, unlike fluconazole which shows a much wider range of concentrations with intermediate inhibition. Like iron chelator bipyridine, Ciclopirox reduces cell growth by binding to iron ions, which can be reversed by addition of FeCl3. Moreover, Ciclopirox treatment at subinhibitory concentration (0.6 μg/mL) only moderately reduces the virulence genes such as genes encoding secreted proteinases or lipases, but leads to a distinct up- or down-regulation of genes encoding iron permeases or transporters (FTR1, FTR2, and FTH1), a copper permease (CCC2), an iron reductase (CFL1), and a siderophore transporter (SIT1). Although the Candida drug resistance genes CDR1 and CDR2 are up-regulated after Ciclopirox treatment, no change in resistance or increased tolerance could be observed even after an incubation period of 6 months, in contrast to fluconazole in which the MICs for cells noticeably increase after 2 months. [1] Ciclopirox inhibits the growth of Aspergillus fumigatus strain B5233 with IC50 of 4.22 μM, more potently compared with deferiprone with IC50 of 1.29 mM. [2]
Features Exhibits antifungal activity via a specific iron limiation mechanism, with no single case of fungal resistance reported.

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    C. albicans strain SC5314

  • Concentrations

    Dissolved in DMSO, final concentrations 10 μg/mL

  • Incubation Time

    1-10 hours

  • Method

    Sabouraud glucose medium (2%) is used for cell culture growth, and RPMI 2% glucose medium and 2% Sabouraud glucose medium are used for MIC determinations. For cell culture growth curves, 220 mL of 2% Sabouraud glucose medium containing different concentrations of Ciclopirox are inoculated with 105 cells/mL, and the mixture is shaken at 160 rpm and 37 °C for 1-10 hours. Growth is measured photometrically at 630 nm. FeCl3 or 2,2'-bipyridine is added to the medium at different concentrations for inhibition studie
