Solution Overview
Problem
The increasing resistance to existing antibiotics necessitates the development of alternative antimicrobial agents, and mammalian milk-derived peptides offer a valuable source of antimicrobial compounds that can effectively target bacteria, fungi, and viruses.
Innovation Solution
Milk-derived peptides with specific amino acid sequences (SEQ ID NOS: 1-295) are formulated into compositions, optionally with excipients such as solvents, viscosity increasing agents, and organic acids, to provide antimicrobial activity for therapeutic and cosmetic applications, including treatment of antibiotic-resistant strains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing antibiotics are used, then antimicrobial treatment is effective, but bacterial resistance develops worsening treatment efficacy
Solution Approach 1:
The patent changes the chemical parameter by using milk-derived peptides with specific amino acid sequences (SEQ ID NOS: 1-295) instead of conventional antibiotics. These peptides exhibit antimicrobial activity against resistant strains through their unique structure and mode of action, thereby maintaining efficacy while overcoming resistance issues
Solution Approach 2:
The patent applies local quality by utilizing specific fragments of milk proteins that are released during infant digestion. These peptides have localized antimicrobial properties that are active against specific pathogens while being safe for infant consumption, addressing both efficacy and safety requirements
2Reliability
If milk-derived peptides are developed as alternatives, then antibiotic resistance is overcome, but formulation complexity increases
Solution Approach 1:
The patent achieves universality by formulating peptides with multiple excipients that serve various functions simultaneously. The composition includes solvents for solubility, viscosity increasing agents for stability, and organic acids for pH control and additional antimicrobial activity, creating a multi-functional formulation that addresses efficacy, stability, and safety
Solution Approach 2:
The patent creates composite materials by combining milk-derived peptides with various excipients to form stable formulations. This composite approach enhances the peptide's stability, solubility, and antimicrobial efficacy while controlling release and maintaining safety for therapeutic and cosmetic applications
3Reliability
If peptides are used for therapeutic purposes, then antimicrobial activity is achieved, but stability and shelf-life of formulations must be maintained
Solution Approach 1:
The patent applies preliminary action by incorporating stability-enhancing excipients into the formulation before use. Viscosity increasing agents and organic acids are pre-added to maintain peptide stability, prevent degradation, and ensure consistent antimicrobial activity throughout the shelf-life of the product
Solution Approach 2:
The patent changes physical parameters by adjusting pH through organic acids and controlling viscosity with thickening agents. These parameter modifications create optimal conditions for peptide stability while maintaining antimicrobial efficacy, solving the contradiction between activity and stability
