Biological Activity for Ascomycin
Ascomycin is a analog of FK 506 (Cat. No. 3631); binds to FK 506-binding protein 12 (FKBP12) in order to inhibit calcineurin phosphatase activity (IC50 = 49 nM) and activation of nuclear factor of activated T cells (NFAT). Displays antifungal and immunosuppressive activities.
