Ascomycin (Synonyms: Immunomycin; FR-900520; FK520)

Cat. No.: HY-13557 Purity: 99.62%
Handling Instructions

Ascomycin (Immunomycin; FR-900520; FK520) is an ethyl analog of Tacrolimus (FK506) with strong immunosuppressant properties. Ascomycin is also a macrocyclic polyketide antibiotic with multiple biological activities such as anti-malarial, anti-fungal and anti-spasmodic. Ascomycin prevents graft rejection and has potential for varying skin ailments research.

    Description

    Ascomycin (Immunomycin; FR-900520; FK520) is an ethyl analog of Tacrolimus (FK506) with strong immunosuppressant properties. Ascomycin is also a macrocyclic polyketide antibiotic with multiple biological activities such as anti-malarial, anti-fungal and anti-spasmodic. Ascomycin prevents graft rejection and has potential for varying skin ailments research[1][2].

    In Vitro

    Ascomycin (FR-900520) suppresses immune response in vitro with an IC50 value of 0.55 nM for mouse mixed lymphocyte reaction[1].
    Ascomycin is a powerful calcium-dependent serine/threonine protein phosphatase (calcineurin [CaN], protein phosphatase 2B) inhibitors. Its mechanism of action involves the formation of a molecular complex with the intracellular FK506-binding protein-12 (FKBP12), thereby acquiring the ability to interact with CaN and to interfere with the dephosphorylation of various substrates[3].

    In Vivo

    Ascomycin (FR-900520; i.m.; 0.32-32 mg/kg; 5 days a week; for 2 weeks) clearly prolongs skin allograft survival in rats[1].
