Mechanisms

The pathways peptides act through — and which compounds use each.

GLP-1 receptor agonism

Activating the GLP-1 receptor to enhance insulin release, slow gastric emptying, and reduce appetite.

4 compounds

GIP receptor agonism

Activating the GIP receptor, another incretin pathway, often combined with GLP-1.

2 compounds

Glucagon receptor agonism

Engaging the glucagon receptor to influence energy expenditure and metabolism.

1 compounds

GHRH signalling

Stimulating the pituitary's GHRH receptor to release growth hormone.

5 compounds

Ghrelin-receptor agonism

Acting on the ghrelin / GH-secretagogue receptor to release growth hormone.

4 compounds

IGF-1 pathway

Downstream growth signalling mediated by insulin-like growth factor 1.

3 compounds

Melanocortin receptor activation

Engaging melanocortin receptors, relevant to pigmentation and sexual function.

2 compounds

Copper-peptide signalling

Copper-binding peptides studied in skin, wound, and collagen biology.

1 compounds

Angiogenesis & tissue repair

Promoting new blood-vessel formation and repair signalling.

3 compounds

Thymic & immune modulation

Modulating immune-cell activity and inflammation.

3 compounds

Antimicrobial membrane activity

Host-defense peptides that disrupt microbial membranes.

1 compounds

Kisspeptin & reproductive signalling

Upstream control of reproductive-hormone release.
