Fused Heteroaryl Compounds for Sodium Channel Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for neurological and cardiac conditions associated with abnormal late sodium current (INaL) are inadequate, as existing pharmaceutical compounds lack specificity and efficacy in modulating sodium channel activity.
Innovation Solution
Development of fused heteroaryl compounds that selectively target and modulate sodium ion channels, specifically designed to prevent or treat conditions related to aberrant sodium channel function, such as epilepsy, neurodevelopmental disorders, pain, and neuromuscular disorders, by administering these compounds to subjects in need.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pharmaceutical compounds are used to treat conditions related to abnormal late sodium current, then treatment is provided, but the compounds lack specificity and efficacy in modulating sodium channel activity
Solution Approach 1:
The patent applies parameter changes by systematically modifying chemical structure parameters of the compounds. Specifically, the invention varies substituents at different positions (R1-R7 groups), changes heteroatom compositions (X, Y, Z being N or CR'), and adjusts ring fusion patterns to optimize sodium channel modulation efficacy while maintaining manageable structural complexity
Solution Approach 2:
The patent employs composite material principles by creating fused heteroaryl compounds that combine multiple aromatic ring systems with heteroatoms. These composite structures (comprising fused rings with substituents) provide enhanced specificity for sodium channel binding while maintaining drug-like properties and manageable complexity through systematic structural design
2Reliability
If existing pharmaceutical compounds are used, then treatment is provided, but they lack specificity in targeting sodium ion channels
Solution Approach 1:
The patent applies local quality by introducing specific heteroatoms (nitrogen or oxygen) at defined positions within the fused ring system, and by placing specific substituents (R1-R7 groups including deuterium, halogens, and functional groups) at particular locations. This localized structural differentiation enhances specificity for sodium channel binding while keeping the overall molecular framework manageable
Solution Approach 2:
The patent systematically varies chemical parameters including heteroatom placement (X, Y, Z positions), substituent types (R1-R7 groups), and ring fusion patterns to optimize specificity for sodium channel modulation while maintaining reasonable molecular complexity
