Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current S1P1 agonists for treating conditions like multiple sclerosis and autoimmune diseases have limitations in selectivity and efficacy, particularly in addressing inflammatory responses and lymphocyte migration.
Innovation Solution
Development of novel acetophenone oxime compounds with specific structural moieties that act as selective S1P1 agonists, enhancing immunomodulatory effects and reducing inflammation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current S1P1 agonists are used for treating multiple sclerosis and autoimmune diseases, then immunomodulatory effects are achieved, but selectivity and efficacy are limited
Solution Approach 1:
The patent modifies molecular parameters of S1P agonists by introducing specific structural features (acetophenone oxime core, heterocyclic substituents at defined positions) to enhance selectivity for S1P1 receptor while maintaining immunomodulatory activity. This resolves the contradiction by changing chemical structure parameters to achieve both high selectivity and broad therapeutic applicability
Solution Approach 2:
The invention creates composite molecular structures combining acetophenone oxime scaffold with various heterocyclic groups (pyridine, pyrimidine, triazole, etc.) to develop next-generation S1P1 agonists. These composite structures provide improved selectivity and efficacy while retaining the desired immunomodulatory effects across multiple disease indications
2Reliability
If selective S1P1 agonists are developed to enhance immunomodulatory effects, then efficacy is improved, but structural complexity increases
Solution Approach 1:
The patent segments the S1P agonist molecule into distinct functional modules: a core acetophenone oxime structure, heterocyclic substituent groups at specific positions, and optional additional substituents. This modular segmentation allows systematic optimization of efficacy while managing structural complexity through defined building blocks
Solution Approach 2:
The invention applies local quality by introducing heterocyclic groups at specific positions (R1, R2, R3, R4, R5, R6) of the acetophenone oxime core, where each position can be independently optimized. This localized modification approach enhances efficacy at specific molecular interaction sites without requiring complex changes throughout the entire molecular structure
