Solution Overview

Problem

Brain-nervous system diseases, such as mental disorders and neurodegenerative diseases, are difficult to treat due to unknown causes, and stress-induced glucocorticoids lead to neural stem cell death, impairing cognitive function and emotional disorders.

Innovation Solution

A composition containing a compound represented by Formula 1, its solvate, stereoisomer, or pharmaceutically acceptable salt, which inhibits neural stem cell death and conserves their number, thereby preventing or treating brain-nervous system diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If glucocorticoids are secreted in excess for a long time due to strong and persistent stress, then the body's immunity is degraded and brain cell damage occurs, but the body's ability to tolerate stress and maintain normal function is reduced

Engineering Contradiction:

Improvebody's ability to tolerate stressVSAvoidstress-induced glucocorticoid secretion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

RITA serves as a protective intermediary substance that intervenes in the stress response pathway. It prevents glucocorticoids from directly damaging neural stem cells by acting as a mediator that blocks the harmful interaction between stress hormones and brain cells, thereby protecting neural stem cell survival while allowing the stress response to occur

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful effect of glucocorticoid secretion into a beneficial outcome by using RITA to selectively protect neural stem cells. The stress response and glucocorticoid secretion are allowed to occur naturally, but RITA transforms the situation by preventing cell death, effectively converting the harmful stress exposure into a controlled condition that can be tolerated and even potentially beneficial through the activation of protective mechanisms

Inventive Principle:

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

2Reliability

If neural stem cells are damaged by stress-induced glucocorticoids, then brain-nervous system diseases occur, but the exact causes remain unknown making treatment difficult

Engineering Contradiction:

Improveprevention and treatment of brain-nervous system diseasesVSAvoidexact causes of brain-nervous system diseases

Core Design Contradiction:

ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent extracts and identifies a specific mechanism (glucocorticoid-induced neural stem cell death) from the complex and unknown etiology of brain-nervous system diseases. By isolating this particular pathway, the invention transforms an undifferentiated problem into a targeted therapeutic approach using RITA to specifically address this extracted mechanism

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies preliminary protective action by administering RITA before stress-induced damage occurs. This preventive approach addresses the disease mechanism before clinical symptoms manifest, making the treatment easier to implement and more effective by intervening at the cellular level rather than treating established disease states

Inventive Principle:

Principle #10Preliminary action
