Clavanin vs Pyrrhocoricin

Clavanin vs Pyrrhocoricin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Clavanin
Antimicrobial Peptide

Clavanin is a histidine-rich alpha-helical antimicrobial peptide originally isolated from the tunicate Styela clava. It is active at low pH, suggesting a role in intracellular killing of phagocytosed bacteria....

Pyrrhocoricin
Antimicrobial Peptide

Pyrrhocoricin is a proline-rich antimicrobial peptide from the hemipteran insect Pyrrhocoris apterus (firebug). Unlike membrane-lytic AMPs, pyrrhocoricin exerts its effects by penetrating bacterial cells and interfering with intracellular targets, specifically the bacterial heat ...
