Solution Overview

Problem

Current diagnostic methods for neurodegenerative diseases like Parkinson's lack specific tracers for early detection of alpha-synuclein aggregates, hindering early diagnosis and effective monitoring.

Innovation Solution

Development of radiolabeled compounds with affinity for alpha-synuclein, beta-amyloid, and tau fibers, utilizing fluorine-18 (18F) or other radioelements for PET/SPECT imaging to detect and quantify these protein aggregates in vivo.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If radiolabeled tracers are used for PET/SPECT imaging, then early detection capability is improved, but specific tracers for alpha-synuclein aggregates are not available

Engineering Contradiction:
Improveearly detection capabilityVSAvoidavailability of specific tracers
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent modifies the chemical structure of compounds by changing parameters such as substituting aromatic rings with different heteroatoms, adjusting linker lengths, and varying functional groups to optimize binding affinity and selectivity for alpha-synuclein aggregates while maintaining radiolabeling capability

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates composite radiotracers by combining radioactive isotopes (18F, 11C, 123I, 124I) with organic ligand structures that have specific affinity for alpha-synuclein aggregates, forming hybrid molecules that possess both detectability and target-specific binding properties

Inventive Principle:
Principle #40Composite materials

2Reliability

If clinical imaging methods are used, then diagnosis can be performed, but early stage aggregates cannot be detected

Engineering Contradiction:
Improvediagnosis capabilityVSAvoiddiagnosis timing
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent enables preliminary detection of alpha-synuclein aggregates before clinical symptoms appear by using radiolabeled tracers that can detect early-stage aggregates, allowing diagnosis and intervention to occur earlier in the disease progression timeline

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If current diagnostic methods are used, then clinical criteria can be applied, but molecular imaging tracers for alpha-synuclein are unavailable

Engineering Contradiction:
Improvediagnostic procedureVSAvoidaggregate detection
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces radiolabeled compounds as intermediary molecules that bridge the gap between clinical imaging technology and alpha-synuclein aggregates, enabling the imaging equipment to detect the aggregates indirectly through the tracer molecules that specifically bind to them

Inventive Principle:
Principle #24Intermediary (Mediator)
