Solution Overview

Problem

Current treatments for Parkinson's disease and other synucleinopathies lack effective methods to inhibit alpha-synuclein mediated toxicity and aggregation, which contribute to neuronal dysfunction and death.

Innovation Solution

Identification and modulation of specific genes and proteins, such as PPP2CB, PPP6C, and KLF11, through compounds that inhibit or enhance their expression or activity to mitigate alpha-synuclein toxicity, using nucleic acids, small molecules, or osmolytes like trehalose to treat or prevent synucleinopathies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for Parkinson's disease are used, then symptomatic relief is achieved, but effective inhibition of alpha-synuclein mediated toxicity and aggregation is not provided

Engineering Contradiction:
Improveeffectiveness of toxicity inhibitionVSAvoidalpha-synuclein mediated toxicity
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent identifies specific genes and proteins (PPP2CB, PPP6C, KLF11) as intermediary targets that mediate alpha-synuclein toxicity. By modulating these intermediary proteins rather than directly targeting alpha-synuclein, the invention achieves effective toxicity inhibition through established molecular pathways.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention changes the molecular parameters of the disease mechanism by targeting specific protein expression and activity levels. Compounds are designed to alter the expression or activity of intermediary proteins (PPP2CB, PPP6C, KLF11), thereby changing the toxicological parameters of alpha-synuclein aggregation and neuronal damage.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If alpha-synuclein aggregation is allowed to proceed, then fibril formation occurs, but neuronal dysfunction and death are accelerated

Engineering Contradiction:
Improvefibril formationVSAvoidneuronal dysfunction and death
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful aggregation process into a beneficial controlled process by targeting specific intermediaries (PPP2CB, PPP6C) that regulate fibril formation. By modulating these intermediaries, the invention transforms uncontrolled toxic aggregation into controlled, less harmful fibril formation, thereby protecting neurons.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The invention uses intermediary proteins (PPP2CB, PPP6C, KLF11) as mediators between alpha-synuclein aggregation and neuronal damage. These intermediaries control the aggregation process, allowing fibril formation to occur in a regulated manner that prevents direct neuronal toxicity while maintaining structural integrity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If no specific target proteins are identified, then treatment development is simplified, but therapeutic efficacy is reduced

Engineering Contradiction:
Improvetreatment developmentVSAvoidtherapeutic efficacy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent segments the complex alpha-synuclein toxicity pathway into specific targetable components (PPP2CB, PPP6C, KLF11). By dividing the overall toxicity mechanism into discrete protein targets, the invention simplifies drug development while maintaining high therapeutic efficacy through focused molecular intervention.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the development approach by shifting from non-specific to specific parameter targeting. By identifying and targeting specific protein parameters (expression levels, activity of PPP2CB, PPP6C, KLF11), the patent achieves both simplified development through clear targets and high efficacy through precise molecular modulation.

Inventive Principle:
Principle #35Parameter changes
