Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compounds that can modulate brain excitability and treat CNS-related disorders, as existing therapies like benzodiazepines and barbiturates have limitations and new neuroactive steroids are required to address these conditions.
Innovation Solution
Development of compounds, such as those represented by Formulas (I-I) to (II-III), which act as GABA modulators, specifically targeting the GABAA receptor to regulate chloride ion flow and influence brain excitability, thereby treating CNS-related disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing therapies like benzodiazepines and barbiturates are used to treat CNS disorders, then brain excitability can be modulated, but therapeutic limitations and side effects occur
Solution Approach 1:
The patent applies parameter changes by developing novel chemical compounds with modified molecular structures (Formulas I and II) that interact with the GABA receptor complex. These structural parameter changes create new neuroactive steroids that modulate brain excitability with improved therapeutic profiles, addressing the limitations of existing benzodiazepines and barbiturates while reducing harmful side effects.
2Adaptability or versatility
If new neuroactive steroids are developed to treat CNS disorders, then therapeutic options are expanded, but compound development complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex compound development into systematic categories: Formula I compounds with specific structural features, Formula II compounds with alternative structures, and defined substituent options (R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12). This segmented approach to molecular design enables systematic exploration of therapeutic options while managing development complexity through organized structural variations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These compounds effectively modulate brain excitability and provide therapeutic benefits for conditions like depression, seizure activity, and anxiety by interacting with the GABAA receptor, offering potential treatments for a range of CNS disorders.
Implementation Method 1
GABA interacts with its recognition site on the GRC to facilitate the flow of chloride ions down an electrochemical gradient of the GRC into the cell
