Solution Overview

Problem

Current therapeutic agents for diabetes, particularly DPPIV inhibitors and GLP-1 secretion accelerators, often cause side effects and have poor intestinal absorptivity due to their large peptide size and complexity.

Innovation Solution

A collagen peptide mixture obtained through a two-step enzymatic treatment, containing peptides like Glu-Hyp-Gly, Leu-Hyp-Gly, and Pro-Ala, which exhibit DPPIV inhibitory and GLP-1 secretion accelerating activities, are developed to enhance safety and absorptivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synthetic DPPIV inhibitors are used to achieve high drug efficacy, then diabetes therapy effectiveness is improved, but side effects such as hypoglycemia occur

Engineering Contradiction:
Improvedrug efficacyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces synthetic pharmaceutical products with peptides obtained from food or drink materials through enzymatic degradation. These natural peptides are designed to be temporary, biodegradable molecules that perform the therapeutic function without accumulating in the body, thereby reducing long-term side effects while maintaining acute therapeutic efficacy.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the chemical parameters of the active compounds by using enzymatically degraded peptides from natural food sources instead of synthetic molecules. This parameter change transforms the drug from a synthetic chemical compound to a biologically derived peptide, altering its metabolic pathway and reducing harmful side effects like hypoglycemia while preserving DPPIV inhibitory activity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If long peptides are used to achieve DPPIV inhibitory activity, then therapeutic effect is improved, but intestinal absorptivity deteriorates

Engineering Contradiction:
ImproveDPPIV inhibitory activityVSAvoidintestinal absorptivity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies segmentation by breaking down collagen from food materials into smaller peptide fragments through controlled enzymatic degradation. Instead of using intact long peptides that cannot be absorbed, the collagen is segmented into smaller units that retain DPPIV inhibitory activity while being small enough to cross the intestinal barrier and be absorbed into the bloodstream.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the molecular size parameter of the peptides by controlling the degree of enzymatic degradation. The degradation is optimized to produce peptides of a specific size range - small enough for intestinal absorption but large enough to maintain the structural features necessary for DPPIV inhibitory activity and GLP-1 secretion acceleration.

Inventive Principle:
Principle #35Parameter changes
