XKFAA Polypeptide Sequences for C. elegans Lifespan Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-aging interventions lack a reliable indicator for measuring healthy lifespan and effectively prolonging it while reducing aging-related diseases and degeneration, with existing anti-aging drugs often being synthetic and potentially harmful.
Innovation Solution
A polypeptide with the amino acid sequences XKFAA, TKFAA, or AKFAA, or their acyl derivatives, is used to prepare anti-aging drugs or supplements, enhancing movement behavior and anti-stress ability, and prolonging lifespan in Caenorhabditis elegans without affecting growth or reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic anti-aging drugs are used, then anti-aging effects are achieved, but harmful side effects and safety issues arise
Solution Approach 1:
The patent changes the chemical structure parameter from synthetic compounds to natural amino acid sequences (XKFAA, TKFAA, or AKFAA), fundamentally altering the substance's properties to achieve anti-aging effects with reduced toxicity and improved safety profile
Solution Approach 2:
The patent uses simple, naturally occurring amino acids that can be easily synthesized and degraded by the body, replacing complex synthetic drugs with shorter-lived, more biocompatible molecular structures that reduce accumulation and long-term toxicity
2Duration of action of stationary object
If existing anti-aging interventions are applied, then lifespan extension is achieved, but healthy lifespan and quality of life are not effectively improved
Solution Approach 1:
The patent employs multiple assessment indicators including movement ability, stress resistance, and lifespan measurements to create a feedback system that evaluates both quantity and quality of life extension, ensuring interventions genuinely improve healthy lifespan rather than merely extending total lifespan
Solution Approach 2:
The patent changes the measurement parameters from simple lifespan duration to composite indicators including movement ability, stress resistance, and overall health status, enabling comprehensive evaluation of healthy lifespan extension
3Reliability
If polypeptide administration is increased to enhance anti-aging effects, then movement ability and stress resistance improve, but adverse effects may increase
Solution Approach 1:
The patent optimizes the dosage parameter to a specific low concentration range (10^-12 to 10^-6 M), changing from high-dose conventional therapy to low-dose precision therapy that achieves therapeutic effects while minimizing adverse reactions

AI summary
Disclosed is a polypeptide capable of prolonging the lifespan of Caenorhabditis elegans, or pharmaceutically acceptable salts thereof. The polypeptide has an amino acid sequence XKFAA SEQ ID NO: 1) (X: any amino acid, preferably T/A). Further, after one or more amino acids on the foregoing polypeptide sequence are deleted, substituted, or added, the resulting polypeptide or the pharmaceutically acceptable salts thereof still have the anti-aging activity. The polypeptide has the effect of prolonging the lifespan of Caenorhabditis elegans and anti-aging, and also has the function of enhancing the ability of movement behavior, improving the anti-stress ability, and alleviating the decline of movement ability in the aging process.
