Solution Overview

Problem

Current treatments for allergic diseases, such as asthma, are inefficient and often have significant side effects due to non-selective immune system activation and high toxicity, with existing therapies failing to effectively reduce symptoms and hyperreactivity.

Innovation Solution

The use of immunomodulator compounds, specifically γ-D-glutamyl-L-tryptophan (SCV-07), which modulates the immune response by shifting the balance of T-helper cells towards Type 1, reducing eosinophilia and bronchial hyperreactivity, administered through various routes to achieve targeted therapeutic effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments (anti-inflammatories, antihistamines, corticosteroids) are used to treat allergic diseases, then symptom relief is provided, but treatment efficiency is low and side effects are significant

Engineering Contradiction:
Improvetreatment efficiencyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the fundamental parameter of immune regulation by introducing a compound that shifts the Th1/Th2 balance, rather than simply suppressing symptoms. This parameter change enables effective treatment with reduced side effects by addressing the root cause of allergic disease through selective immune modulation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses an intermediary substance (the immunomodulator compound) that mediates between the immune system and allergic response. This compound acts as a selective regulator that promotes Th1 cytokine production without causing the broad suppression and side effects of conventional treatments.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If IFN-γ is administered to shift T-helper balance towards Type 1, then Th1 response is enhanced, but bronchial hyperreactivity increases and treatment reliability is insufficient

Engineering Contradiction:
ImproveTh1 cytokine levelVSAvoidtreatment consistency
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies local quality by creating a compound with specific molecular structure (γ-glutamyl dipeptide) that selectively modulates immune response. This localized molecular design enables the compound to enhance Th1 response without causing the adverse effects of non-selective IFN-γ administration, achieving consistent and reliable treatment.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses a composite approach by combining γ-glutamyl dipeptide structure with specific amino acid sequences to create an immunomodulator with balanced properties. This composite molecular structure enables simultaneous enhancement of Th1 response and reduction of side effects, improving treatment reliability.

Inventive Principle:
Principle #40Composite materials

3Quantity of substance

If recombinant interleukin-12 is administered to reduce eosinophilia, then eosinophil levels decrease, but bronchial hyperreactivity and symptoms persist with high toxicity

Engineering Contradiction:
Improveeosinophil levelVSAvoidtoxicity
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent employs a short-lived, naturally metabolizable dipeptide structure that provides transient but effective immune modulation. This approach reduces cumulative toxicity compared to persistent recombinant cytokines, while still achieving the desired reduction in eosinophilia and improvement in symptoms.

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

4Power

If IL-18 is administered to activate T-helper clones, then immune response is enhanced, but allergic manifestations increase due to polyclonal activation

Engineering Contradiction:
Improveimmune activation levelVSAvoidallergic manifestations
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the approach by using a compound that selectively promotes Th1 differentiation rather than broad polyclonal activation. This inverted strategy of targeted differentiation, rather than general activation, enhances immune power while preventing the exacerbation of allergic manifestations.

Inventive Principle:
Principle #13The other way round (Inversion)
