Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drug regimens for treating neuromuscular disorders such as myasthenia gravis, Lambert-Eaton Syndrome, Charcot-Marie Tooth disease, amyotrophic lateral sclerosis (ALS), spinal muscular atrophy (SMA), and sarcopenia fail to fully restore muscle function in compromised patients.
Innovation Solution
Development of novel CIC-1 ion channel inhibitors, represented by compounds of Formula (I), which inhibit the CIC-1 ion channel to improve or restore neuromuscular function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current drug regimens are used for treating neuromuscular disorders, then treatment is provided, but muscle function is not fully restored
Solution Approach 1:
The patent changes the pharmacological parameter by targeting a different ion channel (CIC-1) compared to conventional treatments. The compounds modify the ionic conductance parameters of skeletal muscle cells by blocking CIC-1 channels, which alters the electrochemical gradient and improves neuromuscular transmission efficiency, thereby restoring muscle function more effectively than current regimens.
2Reliability
If CIC-1 inhibitors are developed, then neuromuscular function is enhanced, but new compound structures must be created
Solution Approach 1:
The patent employs a versatile molecular scaffold (substituted benzoic acid structure) that can serve multiple therapeutic purposes in neuromuscular disorders. By systematically varying substituents at different positions (R1-R6) on this core structure, the compounds achieve both CIC-1 channel blocking activity and improved pharmacological properties, allowing one base structure to fulfill multiple functional requirements.
Solution Approach 2:
The patent applies local quality by introducing specific substituents at particular positions on the benzoic acid ring to optimize different aspects of the compound's performance. For example, electron-withdrawing groups at certain positions enhance binding affinity to CIC-1, while other substituents improve solubility or metabolic stability, allowing each part of the molecule to contribute a specific functional quality.
