Research Profile
5-Amino-1MQ acts as a small-molecule NNMT inhibitor, blocking the methylation of nicotinamide and thereby modulating methyl donor utilization and downstream NAD⁺-related pathways. In preclinical models, NNMT inhibition by 5-Amino-1MQ has been associated with increased NAD⁺ availability, alterations in energy expenditure, and support of investigations into obesity, adipose tissue metabolism, and cellular energy balance.
This compound is suitable for in vitro and in vivo experimental systems studying NNMT biology, nicotinamide and methylation dynamics, and the regulation of metabolic signaling networks. Researchers commonly employ 5-Amino-1MQ as a tool compound to explore NNMT-dependent mechanisms, redox balance, and related epigenetic and metabolic endpoints.
