生物活性

Acetyl tetrapeptide-15 is a synthetic peptide used in the cosmetics for sensitive skin. Acetyl tetrapeptide-15 is derived from endomorphin-2 (Tyr-Pro-Phe-Phe-NH2), a human μ-opioid agonist with selective anti-nociceptive effect. Acetyl tetrapeptide-15 reduces skin hyperreactivity producing inflammatory, chronic and neuropathic pain, by increasing the threshold of neuronal excitability in μ-opioid receptor via an endorphin-like pathway[1].

生物活性

Argireline acetate (Acetyl hexapeptide-3 acetate) is a non-toxic, skin-permeable, antiwrinkle peptide. Argireline acetate significantly inhibits Ca2+ dependent neurotransmitter release (acetylcholine) at the neuromuscular junction. Argireline acetate has antiwrinkle and anti-aging activity[1][2][3].

体外研究
(In Vitro)

The incubation of Argireline solution in different concentrations with human embryonic kidney HEK-293 (IC50 of 34.862 μM) and neuroblastoma IMR-32 cells (IC50 of 68.458 μM)) for 48 h have dose dependent antiproliferative effect. Argireline solution incubated in different concentrations with HSF has a dose-dependent antiproliferative effect on those cells. Cellular proliferation is not effected in Argireline low concentration[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究
(In Vivo)

Argireline is applied to the aged mice twice daily for 6 weeks. There is an improvement in the histological structure of skin tissue in the aged mice; the amount of type I collagen fibers increased, while that of type III collagen fibers decreased. Argireline could improve the histological structure of skin tissue and rejuvenate the aging skin[3].

生物活性

N-Acetyl-Ser-Asp-Lys-Pro, an endogenous tetrapeptide secreted by bone marrow, is a specific substrate for the N-terminal site of ACE.

体外研究
(In Vitro)

N-Acetyl-Ser-Asp-Lys-Pro is degraded specifically by ACE, and its plasma level rises substantially during ACE inhibitor therapy. Flow cytometry of rat cardiac fibroblasts treated with N-Acetyl-Ser-Asp-Lys-Pro shows significant inhibition of the progression of cells from G0/G1 phase to S phase of the cell cycle. Moreover, phosphorylation and nuclear translocation of Smad2 is decreased in cardiac fibroblasts treated with N-Acetyl-Ser-Asp-Lys-Pro[1]. N-acetyl-seryl-aspartyl-lysyl-proline appears to exert this function by blocking the action of a stem cell-specific proliferation stimulator and acts selectively on quiescent progenitors[2]. N-Acetyl-Ser-Asp-Lys-Pro inhibits collagenase expression and activation is associated with increased expression of TIMP-1 and TIMP-2. N-Acetyl-Ser-Asp-Lys-Pro normalizes the IL-1β-mediated increase in MMP-2 and MMP-9 activities and MMP-13 expression[3].

体内研究
(In Vivo)

N-Acetyl-Ser-Asp-Lys-Pro prevents hypertension-induced inflammatory cell infiltration, collagen deposition, nephrin downregulation and albuminuria, which could lead to renoprotection in hypertensive mice[4].
