| Ascomycin Usage And Synthesis |
| Description | Ascomycin (11011-38-4) is an analog of FK-506 (Cat.# 10-1103). Potent immunosuppressant1. Binds to FKBP122 and inhibits calcineurin and NFAT. Ascomycin displays anti-inflammatory effects in skin diseases3. Cell permeable and active in vivo. |
| Uses | A potent immunosuppressive agent and could be used as a potential therapeutic agent for autoimmune diseases. |
| General Description | An ethyl analog of FK506 with similar immunosuppressant properties. Acts by binding to immunophilins. Inhibits the synthesis of Th-1 and Th-2 type cytokines in target cells. |
| Biochem/physiol Actions | Product does not compete with ATP. |
| Enzyme inhibitor | This antifungal antibiotic (FW = 792.02 g/mol; CAS 104987-12-4; Solubility: 50 mM in DMSO), also known as FK520, isolated from Streptomyces hygroscopicus, is also a powerful immunosuppressant. Note that ascomycin is a structural analogue of tacrolimus (or FK506) and, as such, operates by a similar mechanism of action (See Tacrolimus). Ascomycin inhibits allogenic T-lymphocyte proliferation and calcineurin phosphatase activity. |
