Uses
19-Epi FK-506 is an impurity in the synthesis of FK-506 [Tacrolimus] (F370000), an immunosuppressant that blocks T cell proliferation in vitro by inhibiting the generation of several lymphokines, especially IL-2. Shown to inhibit the activity of FK-506 binding protein, thereby reversing its effects on sarcoplasmic reticulum Ca+2 release.
