Selective NNMT inhibitor substrate site-targeting mechanism with IC50 of 1.2 M in reference assay conditions Selectivity over related methyltransferases does not significantly affect other enzymes in the NAD salvage pathway at research concentrations Reduces intracellular 1-methylnicotinamide (1-MNA) formation in cell-based assay models Studied in adipocyte, liver, and skeletal muscle cell-based research models examining NNMT-dependent methylation pathway dynamics Referenced at Sigma-Aldrich (SML2832) and in peer-reviewed literature on NNMT enzyme biology Membrane-permeable quaternary quinolinium scaffold studied for intracellular NNMT target engagement in cell-based models Batch and lot identifiers on all labeling for full laboratory documentation compliance Research Background 5-Amino-1MQ was first characterized as a selective NNMT inhibitor in published research literature in 2018

Using erastin-treated A549 cells, we measured intracellular Fe 2+ , ROS, lipid peroxide, glutathione, glutamate release into the extracellular space, and cystine uptake
The monothiol mechanism for the reduction of non-glutathione disulfides is controversial and at least three different nonexclusive mechanisms have been discussed to date (Fig
12 Shorter-term studies also report selective benefits (often subtle) on blood pressure and/or vascular measures after berry extracts, but effects vary by dose, formulation, and endpoint
We further observed that pretreatment with C1-27 inhibited the transcriptional induction of pro-IL-1 in response to inflammatory stimulus such as the bacterial endotoxin, lipopolysachcharide
