Peptide Derivatives for Basement Membrane Protein Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aging skin exhibits irreversible degeneration characterized by wrinkles, flabbiness, and irregular pigmentation due to reduced anabolic reactions and increased catabolic reactions of collagen and protein components in the basement membrane, leading to impaired skin stability and communication between epidermal and dermal cells.
Innovation Solution
A cosmetic composition containing specific tri- and tetrapeptide derivatives, such as Palm-Lys-Val-Dab-OH and Palm-Lys-Val-Dab-Thr-OH, which are applied topically to stimulate the synthesis of basement membrane proteins like collagen IV, VII, laminin V, and integrin beta4, enhancing their concentration and maintaining skin stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If topical cosmetic compositions are applied to aging skin, then the synthesis of basement membrane proteins should be stimulated, but the peptides must rapidly diffuse through the skin barrier to reach the dermal-epidermal junction
Solution Approach 1:
The patent applies preliminary action by pre-formulating peptides with specific lipophilic modifications (aromatic rings, alkyl chains) before application, enabling them to preemptively overcome the skin barrier diffusion resistance and reach the target site at the dermal-epidermal junction with sufficient concentration to stimulate basement membrane protein synthesis
Solution Approach 2:
The patent changes the chemical parameters of the peptide molecules by introducing lipophilic substituents (aromatic rings, alkyl chains of specific lengths) to modify their diffusion properties, enabling faster penetration through the skin barrier while maintaining the ability to stimulate protein synthesis at the target site
2Stability of the object's composition
If the concentration of basement membrane proteins is increased to improve skin stability, then skin appearance and communication between epidermal and dermal cells improve, but age-related catabolic reactions increase breaking down these proteins
Solution Approach 1:
The patent applies preliminary action by pre-stimulating the synthesis of basement membrane proteins (collagen IV, VII, laminin V, integrin beta4) before age-related degeneration can severely compromise skin structure, thereby maintaining skin stability and preventing the harmful effects of protein breakdown and tissue separation
Solution Approach 2:
The patent applies preliminary anti-action by using peptide derivatives to preemptively counteract the catabolic breakdown processes, stimulating anabolic reactions that synthesize new basement membrane proteins to replace those being degraded by age-related catabolism, thus maintaining net protein levels and skin stability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The peptide derivatives rapidly diffuse through the skin to the dermal-epidermal junction, significantly increasing the synthesis of key basement membrane proteins, thereby improving skin appearance and slowing down age-related breakdown, thus addressing age-related skin degeneration.
Implementation Method 1
They can be diffused rapidly and in a sufficient concentration through the stratum corneum and the epidermis to the site of action in the boundary region between the epidermis and dermis
