Fluorinated SOC Channel Modulators for Autoimmune Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for autoimmune diseases and inflammatory conditions often fail to effectively modulate store-operated calcium (SOC) channel activity, which is crucial for regulating immune responses and cell functions.
Innovation Solution
Development of compounds, such as those represented by Formula (I), (II), (III), (IV), (V), (VI), (VII), and (VIII), that selectively inhibit SOC channel activity, particularly CRAC channel activity, to modulate intracellular calcium levels and interact with proteins like STIM and Orai, thereby reducing inflammatory responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments for autoimmune diseases and inflammatory conditions are used, then treatment is provided, but effective modulation of store-operated calcium channel activity is not achieved
Solution Approach 1:
The patent modifies the chemical structure of SOC channel modulators by changing molecular parameters - specifically incorporating fluorine atoms at defined positions in the molecule structure. This structural parameter change enhances the compound's ability to bind to and modulate SOC channel proteins, thereby achieving reliable modulation of calcium channel activity while reducing harmful inflammatory responses.
Solution Approach 2:
The invention creates composite molecular structures by combining specific pharmacological groups with fluorine-containing moieties. This composite approach allows the molecule to simultaneously interact with multiple target proteins in the SOC channel complex (such as STIM and Orai proteins), achieving multi-point binding that enhances modulation reliability and reduces inflammatory effects.
2Object-generated harmful factors
If SOC channel activity is inhibited to reduce inflammatory responses, then harmful factors are reduced, but intracellular calcium signaling is disrupted
Solution Approach 1:
The patent employs dynamic modulation of SOC channels rather than complete inhibition. The fluorine-containing compounds provide tunable binding affinity, allowing the channel to be partially blocked under certain conditions while remaining functional under others. This dynamic approach enables selective suppression of harmful cytokine release while preserving essential calcium signaling pathways for cell survival and homeostasis.
Solution Approach 2:
The fluorine-containing compounds act as intermediary modulators that interfere with the interaction between STIM and Orai proteins. By binding to intermediate sites in the SOC channel complex, these compounds disrupt the full activation pathway without completely blocking calcium influx, thereby mediating between harmful inflammatory responses and necessary calcium signaling functions.
