5-Amino-1MQ targets one of the most overlooked enzymes in metabolic biology — nicotinamide N-methyltransferase, or NNMT — and blocks it. That single action has downstream effects on fat cell metabolism, NAD⁺ availability, and potentially on aging-related cellular decline. It's a small molecule, taken orally, and it's generated real interest in the longevity and metabolic research communities. The catch: every meaningful result so far has come from animal studies. No completed human clinical trials exist.
The compound's full name is 5-amino-1-methylquinolinium. It was developed specifically to probe what happens when you remove NNMT's brake on the NAD⁺ salvage pathway — and the preclinical data has been compelling enough that it's found its way into the gray-market research chemical space. Whether that translates to humans the way the mouse data suggests is still genuinely unknown.
If you're looking at this page because you're considering using it, or because a clinic has mentioned it, the most important thing to understand upfront is where the evidence actually stands: preclinical, not clinical. That doesn't mean it's without promise. It means the human chapter hasn't been written yet.
Key Takeaways- 5-Amino-1MQ is a selective NNMT inhibitor — it blocks an enzyme that suppresses NAD⁺ production and promotes fat storage, particularly in adipose tissue.
