Heterocyclic Ion Channel Modulators for Pain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sodium channel and calcium channel blockers for pain management have limited efficacy due to side effects such as CNS disturbances, dizziness, nausea, and potentially life-threatening cardiac arrhythmias, highlighting a need for more potent and less side-effect-prone antagonists.
Innovation Solution
Development of compounds that inhibit voltage-gated sodium channels and/or calcium channels, specifically represented by a formula that includes various substituents and ring structures, to treat a range of pain conditions and other disorders with improved potency and reduced side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current sodium channel and calcium channel blockers are used for pain management, then pain relief is achieved, but side effects such as CNS disturbances, dizziness, nausea, and cardiac arrhythmias occur
Solution Approach 1:
The patent applies parameter changes by developing new chemical compounds with modified molecular structures (formula I with various substituents X1-X6, R1-R6 groups) that alter the pharmacological properties of sodium and calcium channel blockers. These structural modifications aim to achieve selective binding to voltage-gated channels while reducing off-target effects that cause CNS disturbances and cardiac arrhythmias, thus maintaining pain relief efficacy while minimizing harmful side effects
Solution Approach 2:
The invention employs composite material principles by creating complex heterocyclic compounds that combine multiple functional groups (pyridine, pyrimidine, triazine rings with various substituents) into a single molecular entity. This composite structure allows the compound to interact selectively with voltage-gated sodium and calcium channels, achieving differential blockade that provides effective pain relief while reducing the incidence of adverse effects associated with simpler, less selective blockers
2Object-affected harmful factors
If existing sodium channel blockers are used to treat pain conditions, then pain management is provided, but potency is limited and side effects are prominent
Solution Approach 1:
The patent utilizes parameter changes by systematically varying chemical parameters (substituents X1-X6 including halo, alkyl, alkoxy, amino groups; ring structures R1-R6) to optimize the balance between potency and side effect profile. These modifications enable the compounds to achieve higher binding affinity for voltage-gated channels while maintaining selectivity that reduces off-target toxicity, thereby improving both potency and safety compared to existing blockers
