S-[2,3-bis(palmitoyloxy)propyl]-Cys-Ser-Lys-Lys-Lys-Lys is a triacyl lipopeptide that is the pentapeptide Cys-Ser-Lys-Lys-Lys-Lys in which the side-chain thiol hydrogen on the Cys residue has been replaced by a 2,3-bis(palmitoyloxy)propyl group. It is an organic sulfide and a diacyl lipopeptide.
Mechanism of ActionPam2 is a synthetic lipopeptide which acts as an agonist at TLR2 and TLR6. Actions at these receptors suggest that Pam2 has potential antiviral properties.
