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

Several enzymes of intermediary metabolism have been identified to bind RNA in cells, with potential consequences for the bound RNAs and/or the enzyme. In this study, we investigate the RNA-binding activity of the mitochondrial enzyme malate dehydrogenase 2 (MDH2), which
Nuclear NAD+ homeostasis governed by NMNAT1 prevents apoptosis of acute myeloid leukemia stem cells.

Metabolic dysregulation underlies malignant phenotypes attributed to cancer stem cells, such as unlimited proliferation and differentiation blockade. Here, we demonstrate that NAD+ metabolism enables acute myeloid leukemia (AML) to evade apoptosis, another hallmark of cancer stem cells. We integrated whole-genome
