AOD-9604 vs 5-Amino-1MQ

AOD-9604 is a synthetic peptide corresponding to the C-terminal fragment (amino acids 176-191) of human growth hormone, with an added tyrosine residue. Preclinical research has documented its lipolytic activity independent of the broader GH-IGF-1 axis, with selective effects on fat metabolism and no measurable impact on glucose homeostasis or IGF-1 levels. This selectivity makes it a focused research tool for adipocyte biology. 5-Amino-1MQ is a small molecule inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that consumes methyl donors and depletes cellular NAD+ pools. By inhibiting NNMT, 5-Amino-1MQ preserves NAD+ availability and shifts adipocyte metabolism toward energy expenditure. Preclinical studies have examined its role in metabolic regulation, fat cell differentiation, and NAD+ salvage pathways.

AOD-9604

Compound Class Peptide (GH fragment)

The Verdict

AOD-9604 and 5-Amino-1MQ both appear in metabolic research but operate through fundamentally different mechanisms. AOD-9604 directly stimulates lipolysis without engaging the broader GH axis, making it useful for studying isolated fat metabolism pathways. 5-Amino-1MQ targets NAD+ availability through NNMT inhibition, addressing metabolic regulation at the cellular energy level. The two are complementary research tools for investigators studying different layers of adipocyte and metabolic biology.

AOD-9604 vs 5-Amino-1MQ — FAQ

Are these compounds chemically related?
No. AOD-9604 is a peptide derived from growth hormone, while 5-Amino-1MQ is a small molecule enzyme inhibitor. They share no structural similarity but both appear in metabolic research.
Why does AOD-9604 not affect IGF-1?
AOD-9604 retains only the lipolytic signaling fragment of growth hormone and lacks the structural domains responsible for GH receptor binding and IGF-1 stimulation.
What is NNMT and why is it relevant?
NNMT (nicotinamide N-methyltransferase) is an enzyme that consumes nicotinamide and S-adenosylmethionine, depleting NAD+ precursors. Inhibiting NNMT preserves NAD+ availability for cellular energy metabolism.
Can they be combined in research?
Their mechanisms are non-overlapping, so combined protocols are possible. However, most research isolates one mechanism at a time to avoid confounding variables.
