Description

Amphotericin B, solublized is a solubilized form of the polyene antifungal or antimycotic, amphotericin B. Amphotericin B is a polyene antifungal or antimycotic compound derived from Streptomyces nodosus.

Standard powder amphotericin B is nearly insoluble in water and requires the addition of sodium deoxycholate to maximize solubility.

    CAS Number

    1397-89-3 (Amphotericin B)

    Molecular Formula

    C47H73NO17 (Amphotericin B)

    Molecular Weight

    924.08 (Amphotericin B)

    Mechanism of Action

    Amphotericin B associates with membrane sterols in mammalian and fungal cell membranes. Amphotericin B forms a pore in these membranes leading to essential ion leakage and ultimately, cell death.

    Storage Conditions

    2-8°C

    Tariff Code

    2941.20.5000

    Spectrum

    Amphotericin B is active against mammalian and fungal (molds and yeasts) cells. Amphotericin B is not toxic to bacteria due to their lack of sterols.

    The following represents MIC susceptibility data for amphotericin B against common fungal pathogens:

    • Candida albicans - 0.001 - 321 μg/mL
    • Candida krusei - 0.001 - 16 μg/mL
    • Coccidioides immitis - 0.0625 - 2 μg/mL
    • Cryptococcus neoformans - 0.2 - 39 μg/mL
    • Fusarium oxysporum - 0.75 - 125 μg/mL

Applications

    Eukaryotic Cell Culture Applications

    Amphotericin B can be used in eukaryotic cell culture to control or prevent fungal contamination. Amphotericin B can be toxic to cell lines at high concentrations and should not be used at concentrations greater than 2.50 µg/mL.

    Microbiology Applications

    Amphotericin B is used as an antimycotic selective agent in several routinely used selective media formulations to inhibit the growth of background fungal growth.
