Problem
The overuse and misuse of antibiotics in China have led to significant bacterial resistance, compromised animal immunity, and ecological damage, necessitating the development of new and efficient antimicrobial alternatives.
Innovation Solution
The development of a novel antimicrobial peptide, Spampcin56-86 from Scylla paramamosain, with a specific amino acid sequence and chemical synthesis method, which exhibits broad-spectrum antibacterial and antifungal activity, and is used in preparing anti-bacterial agents, antifungal agents, and aquatic feed additives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antibiotics are used extensively, then bacterial infections are treated effectively, but bacterial resistance increases and ecological damage occurs
Solution Approach 1:
The patent changes the chemical structure parameters by designing and synthesizing peptide analogs with modified amino acid sequences (e.g., replacing natural amino acids with D-amino acids or non-natural amino acids), thereby altering the peptide's properties to overcome bacterial resistance while maintaining anti-bacterial efficacy
Solution Approach 2:
The patent creates composite peptide structures by combining different amino acid sequences and modifications (e.g., N-terminal acetylation, C-terminal amidation, disulfide bridge formation) to produce peptides with enhanced and broad-spectrum anti-bacterial activity that does not induce resistance
2Adaptability or versatility
If new antimicrobial peptides are developed, then alternative anti-bacterial agents are provided, but synthesis complexity and cost increase
Solution Approach 1:
The patent segments the peptide synthesis process into modular steps using standard solid-phase peptide synthesis (SPPS) methodologies, allowing for systematic assembly of amino acid sequences and facilitating easier optimization and scaling of the synthesis process
Solution Approach 2:
The patent optimizes synthesis parameters including solvent selection (e.g., using DMF, DCM, NMP), coupling reagents (e.g., HBTU, HATU, EDC), and purification conditions to improve yield and purity while reducing synthesis complexity and cost
