    Background

    Ascomycin (FK520) is a 23-membered macrolide lactone produced from the fermentation of Streptomyces hygroscopicus (1). A natural analogue of FK506, Ascomycin (FK520) has the ability to bind to FK506-binding protein 12 (FKBP12), inhibiting calcineurin phosphatase activity, and disrupting the activation of nuclear factor of activated T cells (NFAT) and other various substrates (2). Primarily described as an antifungal antibiotic, Ascomycin (FK520) has shown to be a potent immunosuppressant (IC50 = 0.55 nM) used to prevent the rejection of organ transplants and skin allografts (1,3). Ascomycin (FK520) displays powerful antimalarial properties independent of its immunosuppressive mechanisms of action (2).
