Macrocyclic STING Agonists for Selective Immune Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective compounds for modulating the STING protein and protein complex, which is crucial for activating immune responses against tumors and other disorders.
Innovation Solution
Development of macrocyclic compounds, including those of Formula (I) and Formula (II), and their tautomeric forms, pharmaceutically acceptable salts, and prodrugs, which act as modulators of the STING protein and protein complex, activating or modulating its function for therapeutic benefit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If macrocyclic compounds are developed as STING modulators, then immune response activation is improved, but compound synthesis complexity increases
Solution Approach 1:
The macrocyclic compounds are designed with modular structures containing distinct functional domains: a macrocyclic core structure, substituent groups at specific positions, and pharmacophoric elements. This segmentation allows systematic optimization of immune activation while managing synthesis complexity through standardized building blocks.
Solution Approach 2:
The patent systematically varies chemical parameters including macrocycle ring size, substituent types and positions, stereochemistry, and functional group configurations to optimize STING activation. This parameter-based approach enables rational design of compounds with improved immune response activation while maintaining tractable synthesis routes.
2Reliability
If STING pathway activation is enhanced for tumor treatment, then therapeutic efficacy is improved, but off-target immune activation risks increase
Solution Approach 1:
The macrocyclic compounds are designed to activate STING signaling with specific local characteristics at the protein-ligand interface, enabling selective engagement of the STING pathway while minimizing non-specific immune activation. The structured substitution patterns create localized interaction modes that enhance target specificity.
Solution Approach 2:
The macrocyclic compounds serve as intermediary molecules that bridge exogenous cyclic dinucleotides and the STING protein, providing controlled activation of the pathway. This intermediary role allows modulation of STING signaling intensity and duration, reducing the risk of excessive or prolonged immune activation compared to direct CDN administration.
