Wound Healing Polypeptide Activating Wnt Pathway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound care products, such as steroid and antibiotic ointments, are ineffective for deep wounds and may cause side effects, and existing treatments for promoting wound healing, like epidermal growth factor-based products, are costly and inefficient for severe wounds and scars.
Innovation Solution
A pharmaceutical composition containing a polypeptide with an amino acid sequence that activates the Wnt/β-catenin signal transduction pathway, combined with a protein transduction domain and a linker, to enhance wound healing by promoting re-epithelialization and collagen synthesis, potentially used in conjunction with activators like valproic acid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If epidermal growth factor-based products are used to promote wound healing, then wound healing effect is improved, but production cost increases
Solution Approach 1:
The patent uses a peptide sequence (SEQ ID NO: 1) that copies or mimics the biological activity of epidermal growth factor. This peptide is designed to bind to and activate the EGFR receptor, replicating the wound healing effects of EGF at a fraction of the cost. The peptide serves as a simplified, cost-effective copy of the complex EGF protein structure while maintaining the essential therapeutic function.
Solution Approach 2:
The patent employs a short peptide sequence instead of a large protein molecule. This peptide is chemically synthesized rather than produced through complex biotechnology processes, making it significantly cheaper to produce. The peptide's smaller size and simpler structure allow for more efficient synthesis and lower production costs while still achieving the desired wound healing effect.
2Object-affected harmful factors
If steroid ointment is used to reduce inflammation, then inflammation is suppressed, but side effects such as pockmarks, skin wrinkles, and folliculitis occur
Solution Approach 1:
The patent uses a peptide-based intermediary that mediates the anti-inflammatory effect through a different mechanism than steroids. The peptide activates EGFR signaling pathways that naturally regulate inflammation and tissue repair, providing anti-inflammatory benefits without the immunosuppressive side effects of steroids. This intermediary approach achieves inflammation control through physiological pathways.
Solution Approach 2:
The patent changes the chemical parameter from steroid molecules to peptide molecules. This fundamental chemical parameter change allows the substance to interact with different biological targets (EGFR receptors versus steroid receptors), achieving similar anti-inflammatory outcomes through a different molecular mechanism that avoids steroid-related side effects.
3Object-affected harmful factors
If antibiotic-containing ointment is used for wound treatment, then bacterial infection is prevented, but resistance problem and side effects occur
Solution Approach 1:
The patent converts the limitation of peptides (typically being immunogenic or unstable) into a benefit by designing a specific peptide sequence that activates host defense mechanisms. Rather than directly killing bacteria like antibiotics, the peptide stimulates the body's own immune response and wound healing processes, creating a beneficial indirect anti-infective effect that does not contribute to resistance.
Solution Approach 2:
The patent replaces the mechanical/chemical mechanism of direct bacterial killing (antibiotics) with a biological signaling mechanism (peptide-receptor interaction). The peptide activates cellular signaling pathways that coordinate immune response and tissue repair, substituting the direct antimicrobial action with a more complex but sustainable biological regulation system that avoids resistance development.
