Manufacturer: MilliporeSigma 4819082MG
DescriptionA cell-permeable pyridinylacrylamide compound that acts as a selective, allosteric NAPRT/NAMPT (nicotinamide phosphoribosyltransferase) inhibitor (Ki = 0.4nM for the enzyme/substrate complex; Ki ft. = 0.3nM for the free enzyme), while exhibiting no effect toward NPRT (nicotinic acid phosphoribosyltransferase) activity (82% inhibition of NAPRT activity at 10nM vs no inhibition of NPRT activity at 1µM in K-562 extract). FK866 treatment is shown to induce cell death by depleting NAD+ (Cat. Nos. 481911 and 481915) in HepG2 and NIH-3T3 cultures (by >95% after 24 h treatment of 10nM FK866), likewise the addition of exogenous NAD+ is demonstrated to rescue NIH-3T3 and SH-SY5Y from FK866-induced NAD+-depletion and cell death.
