Solution Overview

Problem

Existing treatments for neurological conditions associated with glutamate excitotoxicity, such as ischemic stroke, epilepsy, Alzheimer's disease, ALS, and depression, are inadequate in enhancing glutamate reuptake to prevent neuronal damage.

Innovation Solution

Development of compounds defined by Formula I, which increase the expression of excitatory amino acid transporter 2 (EAAT2) to enhance glutamate reuptake and reduce neuronal damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing treatments are used for neurological conditions, then current therapeutic approaches are maintained, but glutamate reuptake enhancement is insufficient leading to neuronal damage

Engineering Contradiction:
Improveneuronal protectionVSAvoidglutamate reuptake efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies parameter changes by modifying the expression level of EAAT2 transporter through compound administration. The compounds increase EAAT2 protein expression and function, changing the physiological parameter of glutamate reuptake capacity to prevent excitotoxicity and neuronal damage in neurological conditions

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If EAAT2 expression is increased to enhance glutamate reuptake, then neuronal damage is reduced, but new compound development and administration are required

Engineering Contradiction:
Improveneuronal damageVSAvoidtreatment complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent uses small molecule compounds as intermediaries to activate EAAT2 expression. These compounds serve as mediators between the administered treatment and the desired physiological effect of increased glutamate reuptake, enabling neuronal protection without directly modifying the transporter gene

Inventive Principle:
Principle #24Intermediary (Mediator)
