Solution Overview

Problem

There is a need for potent and selective compounds that modulate Aryl hydrocarbon receptor (AhR) activity to treat various inflammatory conditions, as existing treatments are inadequate in effectively managing diseases such as inflammatory bowel disease, cartilage inflammation, and autoimmune disorders.

Innovation Solution

Development of 1-aryl-1,2,3,4-tetrahydro-β-carboline derivatives and their pharmaceutically acceptable salts, which act as potent and selective AhR-binding compounds, administered to subjects to treat inflammatory diseases and conditions by modulating AhR activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing treatments are used for inflammatory conditions, then treatment coverage is provided, but effectiveness is inadequate

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtreatment coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent modifies chemical parameters of AhR modulators by varying substituents at different positions (R1-R6, Ar groups) to optimize both effectiveness and broad applicability across different inflammatory conditions

Inventive Principle:
Principle #35Parameter changes

2Reliability

If AhR activity is modulated to treat inflammatory diseases, then therapeutic benefits are achieved, but selective compound development is needed

Engineering Contradiction:
Improvetherapeutic benefitVSAvoidcompound selectivity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent introduces specific substituent patterns at different positions of the core structure (e.g., R4 and R5 preferences, Ar group selections) to achieve selective AhR modulation with desired therapeutic outcomes

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent optimizes molecular parameters including substituent types, positions, and combinations to enhance both selectivity for AhR and therapeutic effectiveness across various inflammatory conditions

Inventive Principle:
Principle #35Parameter changes
