Usage And Synthesis
Description
Palmitoyl tripeptide-8 is a synthetic peptide ester based on a α-melanocyte stimulating hormone (α-MSH), originating from POMC, and it is composed by the sequence N-(1-oxohexadecyl)-L-histidyl-D-phenylalanyl-L-argininamide. Palmitoyl Tripeptide-8 is the product obtained by the reaction of palmitic acid and Tripeptide-8, wherein Tripeptide-8 is a three-residue synthetic peptide consisting of arginine, histidine and phenylalanine[1].
benefits
PalmitoylTripeptide-8 has a high affinity with MC1-R, specific anti-inflammatory activity, inhibit effectively lL-8release induced by UVB, maintain and restore anormal skin sensitivity threshold.Its recommended dosage is 0.3~2.5%.
Synthesis
Palmitoyl Tripeptide-8 can be obtained via a solid-phase peptide synthesis using the fluorenylmethyloxycarbonyl (Fmoc) strategy on an ACT496S2 automated synthesizer with PS-Rink amide (RAM) resin. The deprotection and coupling steps are carried out until the desired sequences are synthesized. Final side-chain deprotection and cleavage from the resin with a cleavage cocktail (trifluoroacetic acid/water/triisopropylsilane) afford palmitoyl tripeptide-8.
in vitro
In in vitro models, palmitoyl tripeptide-8 showed the ability to significantly inhibit IL-8 production up to 32% in UVB-irradiated keratinocytes, which was comparable to α-MSH, and also in IL-1 stimulated fibroblasts, reaching 64% inhibition which is greater that the achieved by α-MSH. In skin explants exposed to substance P, palmitoyl tripeptide-8 significantly reduced the number of dilated capillaries and the size of dilated vessels up to 30% and 51%, respectively. Edema was also reduced by 60% due to palmitoyl tripeptide-8. Palmitoyl tripeptide-8 can prevent and soothe an irritative response.
