Solution Overview

Problem

Current therapeutics lack effective solutions for promoting periodontum and oral tissue regeneration through cell proliferation, with no prior design of spermidine complexes specifically optimized for this purpose.

Innovation Solution

The formation of supramolecular complexes comprising polyanionic polymers and spermidine at specific ratios (10:1 to 10^7 eq/eq) that are intimately admixed without covalent bonds, enhancing proliferative and regenerative activities in oral and periodontal tissues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If spermidine is used alone or in conventional formulations, then it can provide basic biological functions, but it lacks high efficiency in promoting periodontum and oral tissue regeneration

Engineering Contradiction:
Improveregenerative efficiencyVSAvoidcell proliferation rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines spermidine with polyanionic polymers to form supramolecular complexes, creating a composite material system that enhances the regenerative efficiency and cell proliferation rate beyond what spermidine can achieve alone. The synergistic interaction between the cationic polyamine and anionic polymer creates a more effective therapeutic agent for periodontum and oral tissue regeneration.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent optimizes the molar ratio parameters of spermidine to polyanionic polymer (specifically hyaluronate) within the range of 1:0.1 to 1:5, with preferred ratios of 1:0.3 to 1:0.7. This parameter optimization ensures the formation of supramolecular complexes with high regenerative efficiency while maintaining stability and preventing precipitation.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If supramolecular complexes are formed with equimolar ratios, then delivery of bioactive agents is improved, but regenerative efficiency for periodontum remains insufficient

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidregenerative activity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent deviates from equimolar ratios by using spermidine to hyaluronate molar ratios of 1:0.1 to 1:5, preferably 1:0.3 to 1:0.7. This non-equimolar optimization creates supramolecular complexes with enhanced regenerative activity for periodontum and oral tissues, while maintaining adequate delivery efficiency. The specific ratio range prevents precipitation and ensures stability.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If polyanionic polymer and spermidine are combined in incorrect ratios, then formulation stability is compromised, but regenerative efficiency cannot be achieved

Engineering Contradiction:
Improveformulation stabilityVSAvoidregenerative efficacy
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent establishes optimal molar ratio parameters of spermidine to polyanionic polymer (1:0.1 to 1:5, preferably 1:0.3 to 1:0.7) that simultaneously ensure formulation stability by preventing precipitation and maximize regenerative efficacy. This parameter optimization resolves the contradiction between stability and efficacy.
