Ponericin vs Theta-Defensin

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

Ponericin
Antimicrobial Peptide

Ponericins are a family of antimicrobial peptides isolated from the venom of the ant Pachycondyla goeldii. They adopt alpha-helical conformations in membrane environments and display broad-spectrum antibacterial and insecticidal activity....

Theta-Defensin
Antimicrobial Peptide

Theta-defensins are the only known cyclic peptides produced in the animal kingdom. Found in rhesus macaques and other Old World primates, they are formed by ligation of two 9-residue alpha-defensin gene products into an 18-residue macrocyclic structure....
