Biochem/physiol Actions

FK-506 also appears to inhibit Na+/Ca2+ exchange. FK-506 and its derivatives demonstrate significant neurodegenerative activity. This property seems to arise via different mechanisms. FK-506 is also useful in treating ophthalmologic complications such as corneal graft rejection, uveoretinitis and allergen induced conjunctivitis.
FK-506 is a potent immunosuppressant, neuroprotective and neuroregenerative, and in vitro T cell proliferation blocker. FK-506 disrupts calcineurin-mediated signal transduction in T lymphocytes and interacts with its FK-506-binding protein-12 (FKBP12).
