Solution Overview

Problem

Current treatments for inflammatory diseases associated with receptor-interacting protein-1 kinase (RIP1) are inadequate, as existing therapies fail to effectively inhibit RIP1 activity, leading to persistent inflammation and tissue damage.

Innovation Solution

Development of novel compounds with a specific chemical formula that selectively inhibit RIP1 kinase activity, thereby reducing inflammation and treating associated diseases.

Engineering Contradictions & Design Principles

1Reliability

If existing therapies are used to treat inflammatory diseases, then treatment is provided, but RIP1 activity is not effectively inhibited, leading to persistent inflammation and tissue damage

Engineering Contradiction:
ImproveRIP1 inhibition effectivenessVSAvoidpersistent inflammation and tissue damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by modifying the chemical structure of RIP1 inhibitors through systematic variation of molecular components. The invention explores different substituents (R1-R6 groups), linkage types (L), and molecular configurations to optimize binding affinity and inhibitory potency. This structural parameter optimization enables effective RIP1 inhibition while minimizing harmful effects, directly resolving the contradiction between reliable inhibition and reduction of harmful factors.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite material principles by integrating multiple functional moieties into a single inhibitor molecule. The compounds combine various pharmacophores and structural elements (including heteroaryl rings, alkyl chains, and functional groups) to create a synergistic inhibitor that effectively targets RIP1. This composite approach enhances inhibitory effectiveness while reducing side effects, addressing the technical contradiction.

Inventive Principle:
Principle #40Composite materials

2Reliability

If novel compounds with specific chemical formulas are developed, then RIP1 kinase activity is selectively inhibited, but the complexity of compound synthesis and characterization increases

Engineering Contradiction:
Improveselective RIP1 inhibitionVSAvoidcompound synthesis and characterization
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the complex inhibitor molecule into distinct functional segments or modules. Each segment (such as specific substituents R1-R6, linkage types L, and core structures) can be independently designed, synthesized, and optimized. This modular segmentation simplifies the overall synthesis process and enables parallel development of different compound series, reducing the complexity burden while maintaining selective RIP1 inhibition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs universality by designing a core molecular framework that can accommodate multiple substituents and configurations. This universal scaffold allows a single base structure to generate multiple inhibitor variants through systematic substitution, reducing the need to synthesize entirely new compounds from scratch. The multi-functional design enables selective RIP1 inhibition across different disease models while streamlining synthesis and characterization efforts.

Inventive Principle:
Principle #6Universality (Multi-functionality)
