Description générale

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.

RNA (New York, N.Y.), 30(7), 839-853 (2024-04-13)
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

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

Molecular metabolism, 87, 101981-101981 (2024-07-07)
The metabolism of different cells within the same microenvironment can differ and dictate physiological or pathological adaptions. Current single-cell analysis methods of metabolism are not label-free. The study introduces a label-free, live-cell analysis method assessing endogenous fluorescence of NAD(P)H and
