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. 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]. 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]. Plasmodium \| \| \| \| \| \| \| \| \| \| [1]. Hatanaka H, et al.
