Synthetic hexapeptide marketed as a topical anti-wrinkle ingredient (e.g. by Lipotec/Lubrizol). Mechanism modelled on the SNAP-25-blocking action of botulinum toxin, but with substantially lower potency and without intramuscular effect. EU-compliant as a cosmetic ingredient (CosIng), not approved as a medicine.
Argireline is a synthetic hexapeptide whose sequence corresponds to the N-terminus of the SNAP-25 protein. In vitro it has been shown to competitively inhibit SNARE complex formation (necessary for vesicle fusion in neurotransmitter release). Topical application is intended — given very limited skin permeation — to attenuate cholinergic signalling at the neuromuscular endplate. The effect is orders of magnitude weaker than intramuscular botulinum toxin; the clinical translatability of the in-vitro observations to the skin microenvironment is contested.
I peptidi arrivano come polvere secca. Una volta disciolti in un liquido (ricostituzione), questo calcolatore risponde a una sola domanda: quanta sostanza c'è in un millilitro di soluzione dopo?
