Solution Overview

Problem

Current treatments for neurodegenerative disorders such as Parkinson's disease, Alzheimer's disease, and multiple system atrophy lack effective inhibitors for c-abl kinase, which contributes to disease progression.

Innovation Solution

Development of a compound with c-abl kinase inhibitory activity, specifically a compound of Formula (I) or its pharmaceutically acceptable salts, for use in pharmaceutical compositions to treat or prevent neurodegenerative disorders by administering a therapeutically effective amount to a subject in need.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for neurodegenerative disorders are used, then existing therapeutic options are limited, but c-abl kinase activity remains un inhibited leading to disease progression

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidavailability of c-abl kinase inhibitors
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the therapeutic approach by specifically targeting c-abl kinase activity with dedicated inhibitors (compounds of Formula I), separating this mechanism from existing neurodegenerative disorder treatments. This allows selective inhibition of c-abl kinase to address α-synuclein pathology while maintaining other therapeutic avenues.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces c-abl kinase inhibitors as an intermediary mechanism between existing treatments and disease progression. These compounds mediate therapeutic effect by specifically blocking c-abl kinase activity, which in turn prevents α-synuclein phosphorylation and aggregation, bridging the gap between current limited options and effective disease modification.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If c-abl kinase activity is not inhibited, then existing treatments can be administered, but α-synuclein aggregation and disease progression continue unchecked

Engineering Contradiction:
Improveavailability of treatment optionsVSAvoidα-synuclein aggregation and neurodegeneration
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful effect of c-abl kinase activity (which drives α-synuclein phosphorylation and aggregation) into a beneficial therapeutic target. By designing inhibitors that specifically block c-abl kinase, the harmful phosphorylation event is prevented, transforming the pathological mechanism into a treatable pathway.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent changes the biochemical parameter of c-abl kinase activity from active to inhibited state using compounds of Formula I. This parameter change prevents the downstream pathological events of α-synuclein phosphorylation and aggregation, thereby stopping disease progression while maintaining treatability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If c-abl kinase inhibitors are developed, then new therapeutic mechanisms are available, but the complexity of targeting specific kinase activity increases

Engineering Contradiction:
Improvetherapeutic mechanismsVSAvoidspecificity of kinase inhibition
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by designing compounds of Formula I with specific structural features that confer selective binding to c-abl kinase. The molecular structure incorporates specific substituents and core moieties that interact with unique residues in the c-abl kinase active site, achieving local specificity without requiring complex multi-component systems.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs asymmetry in the molecular design of c-abl kinase inhibitors, where the compounds exhibit specific chiral centers and asymmetric substitution patterns that enable selective binding to the asymmetric active site of c-abl kinase. This asymmetric design provides high specificity while maintaining structural simplicity.

Inventive Principle:
Principle #4Asymmetry
