5-Amino-1MQ Key Research Facts Chemical name: 5-Amino-1-Methylquinolinium (also abbreviated as 5A-1MQ or 5MQ) Target enzyme: Nicotinamide N-Methyltransferase (NNMT) Mechanism: Competitive inhibition of NNMT reduces 1-MNA production, preserves nicotinamide for NAD+ synthesis and SAM for epigenetic methylation Selectivity: High selectivity for NNMT does not inhibit related SAM-dependent methyltransferases or NAD+ salvage pathway enzymes Membrane permeability: High passive and active transport permeability confirmed in PAMPA and Caco-2 cell assays NNMT expression: Upregulated in obese adipose tissue, multiple cancer types, and aged skeletal muscle tissue contexts of primary research interest Downstream targets: NAD+ availability, SIRT1/SIRT3 activity, SAM-dependent epigenetic methylation, lipogenesis, energy expenditure Pre-clinical models: Diet-induced obese (DIO) mice, 3T3-L1 adipocyte cell models, aged mouse skeletal muscle models, HeLa cancer cell lines In vitro cell viability: No impact on cell viability at 10 M concentration in 3T3-L1 pre-adipocytes in published toxicity profiling What Does 5-Amino-1MQ Do in Research

However, the study used only two germ cell types (type B spermatogonia and spermatocytes), which made it impossible to evaluate the changes in all cell types during spermatogenesis, and the high concentrations of the drug used in the experiment may have led to exaggerated cytotoxic effects that may not reflect the clinical reality
