Comparison

AOD-9604 vs Humanin

Function

While AOD-9604 is studied as an anti-obesity peptide that can reduce weight gain and increase fat oxidation in obese animal models with generally neutral effects on IGF-1 and glucose metabolism in early human trials71111115, Humanin exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival7136141.

Mechanism

While AOD-9604 works as a synthetic fragment of human growth hormone corresponding to residues 176–191 with an added N-terminal tyrosine, retaining lipolytic but not growth-promoting actions; proposed to stimulate lipolysis and inhibit lipogenesis in adipose tissue, partly via β3-adrenergic pathways without significantly activating the full GH receptor–IGF-1 axis6171111, Humanin is a mitochondrial-derived 24-amino-acid peptide that protects cells against diverse apoptotic insults by interacting with cell-surface cytokine receptor complexes and intracellular targets, thereby activating pro-survival STAT3 and other pathways7136141.

Length and Sequence

AOD-9604 is 16 amino acids long, whereas Humanin is longer as it has a length of 24 amino acids. AOD-9604 is made up of a sequence of Tyrosine, Leucine, Arginine, Isoleucine, Valine, Glutamine, Cysteine, Arginine, Serine, Valine, Glutamic acid, Glycine, Serine, Cysteine, Glycine, Phenylalanine. Humanin is made up of a sequence of Methionine, Alanine, Proline, Arginine, Glycine, Phenylalanine, Serine, Cysteine, Leucine, Leucine, Leucine, Leucine, Leucine, Threonine, Serine, Glutamic acid, Isoleucine, Aspartic acid, Leucine, Proline, Valine, Lysine, Arginine, Arginine, Alanine.

Receptor

AOD-9604

Acts indirectly on adipocytes, with mechanistic work implicating β3-adrenergic receptor–linked signaling in fat metabolism rather than direct GH receptor activation71111

Humanin

Binds a trimeric cytokine receptor complex consisting of CNTFR, WSX-1, and gp130, and can also signal via the G-protein–coupled receptor FPRL1/FPR2136141
