FK-506 is a potent immunosuppressant in the same molecular class as cyclosporin A (Cay-12088) and rapamycin (Cay-13346). Its mechanism of action involves the formation of a high affinity complex (Ki = 0.2 nM) with FK-506 binding protein 12 (FKBP12). This complex then inhibits the activity of the...

FK-506 is a potent immunosuppressant and in vitro T cell proliferation blocker. It has been shown to disrupt calcineurin (also known as CaN or phosphatase 2B)-mediated signal transduction in T lymphocytes. The compound interacts with its FK506-binding protein-12 (FKBP12). The resulting complex, in turn,...

An immunosuppressant commonly used in transplant operations to prevent graft-versus-host disease.

Potent immunosuppressant (as cyclosporin A and rapamycin). Suppresses proliferation of cytotoxic T cells and inhibits the production of T cell-derived mediators such as interleukin-2 (IL-2). Forms a complex with FK-506 binding protein 12 (FKBP12). Inhibits the activity of the calcium/calmodulin-dependent protein...

Soluble in DMSO at 100 mg/mL, soluble in ethanol at 100 mg/mL, very poorly soluble in water, maximum solubility in plain water is estimated to be about 10 µM, buffers, serum, or other additives may increase or decrease the aqueous solubility
