Descripción

Descripción general

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.
