A nanohybrid synthesized by polymeric assembling Au(I)-peptide precursor for anti-wrinkle function

Area of Science:

• Biotechnology
• Dermatology
• Nanomedicine

Background:

• Wrinkles are a primary indicator of skin aging, prompting a need for safe and effective anti-wrinkle solutions.
• Botulinum toxin, while effective, presents toxicity and side effect concerns, necessitating alternative treatments.
• Existing peptides show promise but suffer from poor stability and membrane penetration.

Purpose of the Study:

• To develop a stable and bioavailable anti-wrinkle agent by enhancing a synthesized peptide, Skin Peptide.
• To create a peptide-gold nano-hybrid, Skin Pcluster, to overcome the limitations of the original peptide.
• To evaluate the efficacy and safety of Skin Pcluster as an anti-wrinkle treatment.

Main Methods:

• Synthesis of Skin Peptide and its transformation into a peptide-gold nano-hybrid, Skin Pcluster.
• In vitro assessment of Skin Pcluster's effect on acetylcholine release from neurons.
• Inhibition of neuromuscular signal transmission analysis.
• Human clinical trials to evaluate the de-wrinkle effect and safety profile of Skin Pcluster.

Main Results:

• Skin Pcluster demonstrated the ability to reduce acetylcholine release from neurons in vitro.
• Neuromuscular signal transmission was effectively inhibited by Skin Pcluster.
• Human studies confirmed a significant reduction in wrinkles.
• Skin Pcluster exhibited a favorable safety profile in human trials.

Conclusions:

• Skin Pcluster, a bioavailable peptide-gold nano-hybrid, offers an innovative and safe approach to wrinkle reduction.
• The study highlights the potential of nano-hybrid formulations to enhance peptide delivery and efficacy.
• Skin Pcluster represents a significant advancement in anti-aging treatments with broad application potential.
