Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NLRP3 inhibitors have limitations such as low specificity and high safety risks, necessitating the development of new small molecule inhibitors with improved activity for treating autoimmune diseases caused by aberrant NLRP3 activation.
Innovation Solution
A series of nitrogen-containing compounds represented by General Formula I, along with their preparation methods and pharmaceutical compositions, are developed to inhibit NLRP3 with high specificity and activity, including specific synthetic routes and applications in treating NLRP3-related diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing NLRP3 inhibitors are used, then NLRP3 inhibition is achieved, but specificity and safety are compromised
Solution Approach 1:
The patent applies parameter changes by systematically modifying the chemical structure of NLRP3 inhibitors through varying substituents (R1, R2, R3) and core structures in General Formula I. This structural optimization achieves high specificity (IC50 values in μM or nM range) while maintaining safety by minimizing off-target effects on the hERG pathway
Solution Approach 2:
The patent employs composite material principles by designing nitrogen-containing compounds with complex molecular structures comprising multiple functional groups and heterocyclic rings. These composite structures enable selective binding to NLRP3 while avoiding interactions with other targets, thereby achieving both high efficacy and safety
2Ease of manufacture
If simple NLRP3 inhibitor structures are used, then ease of synthesis is improved, but inhibitory activity is limited
Solution Approach 1:
The patent applies segmentation by dividing the NLRP3 inhibitor into distinct structural modules: a core structure (General Formula I) with variable substituents R1, R2, and R3. This modular design allows systematic optimization of activity through substituent variation while maintaining a synthetically accessible core structure
Solution Approach 2:
The patent employs universality by designing a general chemical formula (Formula I) that encompasses multiple specific compounds with different substituents. This universal framework enables a single synthetic route to produce multiple high-activity derivatives, balancing structural complexity with ease of manufacture
