Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing peptides, particularly for reproductive and sexual function stimulation, are costly and inefficient due to multistage synthesis and susceptibility to proteolysis, leading to reduced efficacy and prolonged treatment durations.
Innovation Solution
Development of peptides with the general formula A-Thr-Lys-Pro-B-C-D-X, where specific amino acid residues are selected based on bioinformatic analysis to enhance stability and activity, focusing on the Thr-Lys-Pro tripeptide as a core molecule, and synthesizing tetrapeptides and higher peptides to maintain reproductive and sexual function stimulating activity.

1Productivity
If conventional multistage synthesis methods are used to produce peptides, then peptide production is achieved, but the production cost increases and treatment duration is prolonged
Solution Approach 1:
The peptide structure is segmented into a core stable tripeptide (Thr-Lys-Pro) and variable terminal residues. This segmentation allows the core structure to provide stability and resistance to proteolysis, while the terminal residues can be optimized for specific biological activities, thereby improving production efficiency and reducing treatment duration
Solution Approach 2:
The invention changes the structural parameters of peptides by establishing a specific general formula with constrained amino acid positions. This parameter optimization ensures resistance to proteolysis and enhances reproductive and sexual function stimulating activity, leading to reduced treatment duration and improved productivity
2Productivity
If conventional peptide synthesis methods are used, then peptide production is achieved, but production costs increase
Solution Approach 1:
By optimizing the amino acid sequence parameters according to the general formula, the invention achieves enhanced stability and activity, which reduces the need for complex purification steps and lowers production costs while maintaining high productivity
Solution Approach 2:
The peptide structure combines a stable core tripeptide (Thr-Lys-Pro) with variable terminal residues, creating a composite structure that provides both stability and specific biological activity. This composite approach improves manufacturing efficiency and reduces costs
3Reliability
