Solution Overview

Problem

Current treatments for diseases associated with NF-κB activation, such as cancer, inflammation, and autoimmune diseases, are limited in efficacy and often come with adverse effects, as they primarily target the canonical NF-κB pathway without effectively inhibiting the non-canonical and hybrid pathways.

Innovation Solution

Development of compounds that inhibit the binding of NF-κB components, such as p65, RelB, and c-Rel to DNA, blocking both the canonical and non-canonical pathways, thereby modulating gene expression and signal transduction through the NF-κB pathway.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments targeting only the canonical NF-κB pathway are used, then the treatment mechanism is simple, but the treatment efficacy is limited and cannot effectively inhibit non-canonical and hybrid pathways

Engineering Contradiction:
Improvetreatment efficacyVSAvoidinhibition mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The compound is designed to simultaneously inhibit multiple NF-κB pathways (canonical, non-canonical, and hybrid) through a single molecular structure. This multi-functional inhibitor blocks both canonical pathway components (IκBα, IκBβ, IκBε, p65) and non-canonical pathway components (RelB, c-Rel, p52), achieving broad-spectrum NF-κB inhibition with one agent rather than requiring multiple pathway-specific treatments

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

2Object-affected harmful factors

If existing NF-κB inhibitors like DHMEQ are used, then they show some therapeutic effect, but they exhibit cytotoxicity and reduced potency compared to the new compounds

Engineering Contradiction:
ImprovecytotoxicityVSAvoidinhibitor potency
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The compound optimizes key pharmacological parameters including increasing binding affinity for NF-κB components (p65, RelB, c-Rel) through structural modifications, adjusting molecular properties to enhance selectivity and reduce off-target effects, and tuning the compound's chemical characteristics to improve pharmacokinetic profile and reduce cytotoxicity while maintaining or enhancing inhibitory potency
