PEPTIDES
What is Peptide Therapy?
Peptide therapy uses naturally occurring or synthetic peptides to influence specific biological pathways within the body.
Today, peptide-based medications are already used in conventional medicine for conditions involving:
Diabetes (GLP-1 receptor agonists)
Osteoporosis
Hormone deficiencies
Certain cancers
Blood disorders
Autoimmune diseases
Fertility treatments
Researchers continue to study peptide therapies for their potential roles in tissue regeneration, wound healing, neurodegenerative disease, immune regulation, and healthy aging.
Kambo: A Natural Library of Bioactive Peptides
The secretion of the Amazonian Giant Monkey Frog (Phyllomedusa bicolor) contains approximately 28 characterized peptide sequences belonging to multiple peptide families. Scientists continue to identify additional compounds, making kambo one of the most chemically complex amphibian secretions studied to date.
Unlike a single medication that targets one receptor, kambo contains numerous peptides that interact with several different physiological systems simultaneously.
Opioid Peptides
These peptides interact with receptors that normally respond to the body’s own endorphins.

Orphan Peptides
Researchers have isolated several peptides that do not yet fit into established peptide families.
These compounds remain under investigation, and their biological roles have not yet been fully determined.
Why Are Kambo Peptides Biocompatible?
Many kambo peptides are biologically active in humans because they interact with receptor systems that are conserved across vertebrates. Rather than introducing entirely new biological pathways, these peptides can bind to receptors that humans already possess, including opioid, bradykinin, neurokinin, cholecystokinin, corticotropin-releasing factor, and adenosine receptor systems.
Other peptides, particularly the antimicrobial families, do not primarily target human receptors. Instead, they help protect the frog by disrupting bacterial, fungal, and other microbial cell membranes, which is why they are being investigated as potential templates for new antimicrobial therapies.
