5-Amino-1MQ

NNMT Inhibitor — Small Molecule

Updated April 14, 2026

What is 5-Amino-1MQ?

A small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that methylates nicotinamide and drains the cellular NAD+ pool. By blocking NNMT, 5-amino-1MQ preserves intracellular NAD+ levels and increases SAM (S-adenosyl methionine) availability. In preclinical models, NNMT inhibition reduces adipocyte size, decreases total body mass, and lowers cholesterol without affecting food intake — suggesting a direct metabolic effect independent of appetite modulation.

Research Profile

Structure Small molecule (~173 Da) — methylquinolinium derivative
Targets NNMT enzyme inhibition → NAD+ preservation, SAM increase
Research Focus NAD+ metabolism, adipocyte biology, NNMT pharmacology, metabolic regulation without appetite effects
Reconstitution No reconstitution — oral capsules
Stability Room temperature, dry storage
Key distinction: Preserves cellular NAD+ by blocking the NNMT drain — reduces fat mass without appetite suppression, representing a metabolic mechanism orthogonal to all incretin or monoamine approaches.
