Prodrug eIF2B Modulators for Integrated Stress Response Attenuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current therapies for diseases related to the integrated stress response (ISR) pathway, such as neurodegenerative diseases and cancers, are inadequate in modulating eIF2B activity, leading to insufficient attenuation of translation initiation and cellular stress.
Innovation Solution
Development of compounds represented by Formula (I) that modulate eIF2B activity, either directly or through prodrug mechanisms, to attenuate the ISR pathway, thereby treating various diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current therapies are used to treat diseases related to the ISR pathway, then treatment is provided, but modulation of eIF2B activity is insufficient, leading to inadequate attenuation of translation initiation and cellular stress
Solution Approach 1:
The patent employs parameter changes by modifying chemical structures (Formula I and Formula II with various R1 substituents) to create prodrugs that convert to active compounds capable of modulating eIF2B activity. This allows optimization of pharmacological parameters to achieve sufficient attenuation of the ISR pathway while maintaining therapeutic efficacy.
2Object-affected harmful factors
If phosphorylation of eIF2α is increased to attenuate translation initiation, then cellular stress is reduced, but eIF2B activity is suppressed, blocking ternary complex formation
Solution Approach 1:
The patent uses small molecule compounds as intermediaries that bind to eIF2B and prevent phosphorylated eIF2α from inhibiting eIF2B activity. These compounds act as mediators that allow the beneficial effects of eIF2α phosphorylation (attenuation of pathological protein synthesis) while preventing the harmful suppression of eIF2B function, thus maintaining cellular homeostasis during stress responses.
