Solution Overview

Problem

Current treatments for ABC transporter-mediated diseases, such as cystic fibrosis, lack effective modulators to address defective protein trafficking and activity, leading to impaired ion and fluid transport, and there is a need for compounds that can modulate ABC transporter activity to treat various diseases beyond cystic fibrosis.

Innovation Solution

Development of specific compounds with the general formula II and their pharmaceutically acceptable salts, which act as modulators of ABC transporter activity, particularly CFTR, to increase or decrease activity, thereby treating a range of diseases including cystic fibrosis, emphysema, and other secretory and protein folding diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for ABC transporter-mediated diseases are used, then disease management is maintained, but effective modulation of defective protein trafficking and transporter activity is not achieved

Engineering Contradiction:
Improvedisease treatment effectivenessVSAvoidmodulator availability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent employs parameter changes by developing a series of compounds with varying structural parameters (substituents R1-R6, ring systems, linkers) to modulate ABC transporter activity. The general formula II provides a framework where multiple parameters can be adjusted to optimize binding affinity and functional effects on different ABC transporters, enabling effective treatment of various diseases caused by defective protein trafficking and transporter dysfunction

Inventive Principle:
Principle #35Parameter changes

2Productivity

If ABC transporter activity is not modulated, then current therapeutic approaches are maintained, but ion and fluid transport remains impaired

Engineering Contradiction:
Improveion and fluid transport functionVSAvoidtransporter function
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent uses small molecule compounds as intermediaries that bind to ABC transporters to restore their function. These compounds act as mediators between the defective transporter and normal physiological function, facilitating proper ion and fluid transport by stabilizing transporter conformation, enhancing gating, or improving protein folding and trafficking to the cell membrane

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If compounds with general formula II are developed, then ABC transporter modulation capability is achieved, but development complexity increases

Engineering Contradiction:
Improvetransporter modulation capabilityVSAvoidcompound structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent achieves universality by designing a general formula II that can modulate multiple ABC transporters (CFTR, MDR1, MRP1, etc.) with a single compound framework. This multi-functional approach allows one compound structure to address different transporter deficiencies underlying various diseases, reducing the need for entirely separate drug development programs for each condition

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