Spirocyclic Indane Derivatives for IL-17 Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pharmacological agents fail to effectively modulate IL-17 activity, which is crucial for treating inflammatory and autoimmune disorders, as they do not target the specific structural class of spirocyclic indane derivatives.
Innovation Solution
Development of spirocyclic indane derivatives and their analogues that act as potent modulators of human IL-17 activity, providing a compound of formula (I) or its N-oxide, or a pharmaceutically acceptable salt, for therapeutic use in treating and preventing inflammatory and autoimmune disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pharmacological agents are used to modulate IL-17 activity, then treatment of inflammatory and autoimmune disorders is attempted, but the modulatory effect is insufficient due to lack of specificity for spirocyclic indane derivatives
Solution Approach 1:
The patent applies local quality by introducing specific structural features (spirocyclic indane core with particular substituent patterns at positions R1-R6) to achieve selective binding to IL-17 receptors. The molecular structure is designed with localized functional groups that confer high affinity and specificity for IL-17 modulation, distinguishing these compounds from prior art that lacked this structural precision.
Solution Approach 2:
The patent employs parameter changes by systematically varying molecular parameters (substituent types at R1-R6, heteroatom positions, ring sizes) to optimize IL-17 modulatory activity. This structure-activity relationship analysis allows tuning of pharmacological properties to achieve potent and selective modulation of IL-17 signaling pathways.
2Reliability
If spirocyclic indane derivatives are developed as IL-17 modulators, then therapeutic efficacy for inflammatory and autoimmune disorders is improved, but compound complexity and synthesis difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the spirocyclic indane derivative into distinct functional modules: the core spirocyclic indane structure (providing structural framework), substituent groups at R1-R6 (providing pharmacological activity), and linkage regions (providing flexibility). This modular approach facilitates systematic design and synthesis while maintaining therapeutic efficacy.
Solution Approach 2:
The patent employs the nested doll principle by incorporating multiple ring systems within the spirocyclic indane core structure. The spirocyclic arrangement creates nested cyclic structures that pack functional groups efficiently, achieving high molecular density and specific binding characteristics without excessive overall size or complexity.
3Adaptability or versatility
If spirocyclic indane derivatives with specific structural classes are targeted, then selectivity for IL-17 modulation is achieved, but development time and research complexity increase due to lack of prior art
Solution Approach 1:
The patent applies preliminary action by performing extensive structure-activity relationship analysis and computational modeling before synthesizing the full series of spirocyclic indane derivatives. Key structural features and binding modes are predicted and optimized in advance, allowing the synthesis program to focus only on the most promising compounds and reducing overall development time despite the novel structural class.
