“Targeted inhibition of NNMT improves insulin responsiveness and may protect against diet-induced obesity.” — Hong et al., Nature Medicine ➤ Longevity and Anti-Aging Potential Because NAD⁺ is vital for DNA repair, circadian rhythm regulation, and mitochondrial health, 5-Amino-1MQ is being explored as a geroprotective agent — especially when stacked with NAD boosters or sirtuin activators

Thus, there is a critical need for more effective pharmacological interventions that improve long-term management of obesity and its comorbidities.[11] Recently, nicotinamide-N-methyltransferase (NNMT) has emerged as a novel mechanism-of-action target in the adipose tissue to treat obesity and associated T2D.[12–15] NNMT is a cytosolic enzyme with a newly identified role in modulating cellular energy homeostasis by jointly regulating nicotinamide (NA) and S-(5′-adenosyl)-L-methionine (SAM) flux within the critical intracellular nicotinamide adenine dinucleotide (NAD + ) salvage pathway and methionine cycle, respectively.[15] NNMT expression is upregulated in the white adipose tissue (WAT) of obese and diabetic mice[12] and has significantly higher activity in the WAT compared to its activity in the brown adipose tissue, liver, and lungs of diet-induced obese mice.[16] Furthermore, plasma levels of the NNMT reaction product 1-methylnicotinamide (1-MNA) correlate with adipose NNMT expression, individuals’ body mass index (BMI), and waist circumference, suggesting the target to be clinically relevant.[13, 14] Importantly, mice fed a high-fat diet and treated with antisense oligonucleotides (ASOs) that reduced adipose NNMT expression were protected from diet-induced obesity (DIO) and showed reduced adiposity compared to control animals.[12] Using structure-guided design and binding calculations, we recently generated potent small molecule NNMT inhibitors around a methylquinolinium (MQ)-scaffold.[17] In the present study, we extend these findings to show that the small molecule NNMT inhibitors are highly membrane-permeable, selective inhibitors, which reduce intracellular 1-MNA levels and prevent lipogenesis in vitro
