Cosmetic Peptides
Since 2010 we use a bio-inspired pharmaceutical approach, based on peptides, to scientifically address a target of significant cosmeceutical interest: skin aging.
We choose the collagen degradation pathway as a relevant target for the development of new and original bio-inspired active ingredients.
SA1-III, a Serpin A1-derived peptide. A study funded by the Tuscany Region and performed in collaboration with PeptLab (academic research laboratory of Espikem's founders) led to the development of SA1-III, a short bioactive peptide formally derived from Serpin A1, the physiological inhibitor of elastase, one the enzymes involved in collagen degradation. Cultured human dermal fibroblast treated with SA1-III showed an increase in collagen concentration1, while further studies indicated that the peptide acts as a "protector" of native collagen2.
AAT11RI. Further research activity developed by Espikem in collaboration with PeptLab led to second-generation peptides, described in the patent application WO 2020/245772 A1.
