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.
Ethyl analog of FK-506 that possesses the same potent immunosuppressive properties as the parent compound. Inhibition of the Ca2+/calmodulin activated phosphatase calcineurin (IC50 = 10 nM) by the ascomycin/FK-506 binding protein complex is believed to be important in the mechanism of immunosuppression. Acts by binding immumophilins.
Biochem/physiol Actions
Cell permeable: no
Fully active via yeast rotamase (FK 506 binding protein) inhibition
Primary Target
Immunophilins
Immunophilins
Product does not compete with ATP.
Reversible: no
Preparation Note
Following reconstitution, aliquot and freeze (-20°C). Ethanol stock solutions are stable for up to 3 days at -20°C. Anhydrous DMSO stock solutions are stable for up to 1 month -20°C.
