General description

FK866 is used to treat inflammatory diseases and cancer.

Application

FK866 hydrochloride hydrate has been used:
  • to investigate its effects on intra-axonal NAD+ levels
  • to induce NAD+ depletion
  • to reduce the level of tumor necrosis factor-α (TNF-α), nicotinamide phosphoribosyltransferase (NAMPT) and interleukin-6 (IL-6) in the ischemic brain tissue

Biochem/physiol Actions

FK866 is a potent inhibitor of NAD biosynthesis, and a specific inhibitor of NAMPT (Nicotinamide Phosphoribosyltransferase, visfatin, PBEF). NAMPT functions as an intra-cellular and extra-cellular NAD biosynthetic enzyme that is important for regulating metabolism and stress resistance through sirtuins and other NAD-consuming regulators. NAMPT also acts as a cytokine independent of its enzymatic activity, playing a major part in regulating immune responses.
FK866 is a potent inhibitor of NAD biosynthesis.
