5-Amino-1MQ
5-Amino-1-methylquinolinium / NNMT inhibitor / SBI-477
A small molecule NNMT (Nicotinamide N-methyltransferase) inhibitor — not technically a peptide, but a research compound widely carried by peptide vendors with significant interest in longevity and metabolic research communities. NNMT is an enzyme that consumes NAD+ precursors and promotes fat storage. Inhibiting it raises NAD+ levels and shifts metabolism toward fat burning. Animal data is promising. Human research is limited.
Note: 5-Amino-1MQ is a small molecule NNMT inhibitor, not technically a peptide. We include it because it is carried by most research peptide vendors and researched by the same longevity and metabolic health community.
Mechanism of action
Inhibits NNMT — an enzyme that methylates nicotinamide using SAM (S-adenosyl methionine) as a methyl donor. NNMT activity depletes both NAD+ precursors and the methyl pool. By inhibiting NNMT: NAD+ levels rise (similar effect to NMN/NR supplementation), SAM availability increases supporting methylation reactions, adipocyte differentiation is reduced and existing fat cells shift toward leaner phenotype. Works through a fundamentally different mechanism from GLP-1 compounds — it does not suppress appetite but changes cellular energy metabolism directly.
Effects in the body
5-Amino-1MQ animal data is genuinely interesting for longevity and metabolic researchers. Studies in mice show fat mass reduction without caloric restriction, increased metabolic rate, improved insulin sensitivity, and NAD+ elevation comparable to NMN supplementation. The mechanistic case for human translation is credible. Published human clinical trials are absent as of 2026.
Pros & cons (from the literature)
- NNMT inhibition raises NAD+ through a different mechanism than NMN or NR supplementation
- Fat mass reduction in animal models without caloric restriction
- Oral administration available — no injection required
- Synergistic with NAD+ precursors through complementary mechanisms
- Small molecule stability — does not require cold chain storage like many peptides
- Dual metabolic and longevity research application
- Not technically a peptide — small molecule NNMT inhibitor
- No published human clinical trials as of 2026
- Animal-to-human translation unvalidated
- NNMT has roles beyond fat metabolism — systemic inhibition effects not fully characterized
- Long-term safety profile unknown
- Research community enthusiasm may be running ahead of the published evidence
