Ascomycin Chemical Properties,Usage,Production

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.

Chemical Properties

White powder, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from biological fermentation.

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.

Background

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