α,β-Unsaturated Amide Compounds Improving Capillary Cerebral Blood Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for neurodegenerative diseases like Alzheimer's disease and vascular dementia primarily focus on symptom alleviation rather than addressing the underlying vascular dysfunction, particularly capillary dysfunction, which contributes to cerebral blood flow reduction and associated neuropathological changes.
Innovation Solution
Development of an α,β-unsaturated amide compound that targets capillaries to increase cerebral blood flow, potentially improving symptoms of neurodegenerative diseases by enhancing capillary function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If current treatments focus on symptom alleviation, then patient comfort is improved, but underlying vascular dysfunction and capillary damage are not addressed
Solution Approach 1:
The patent identifies capillary dysfunction and vascular factors as harmful elements that have been overlooked in traditional AD treatment. By targeting these vascular factors with compounds that improve capillary blood flow, the invention converts the previously harmful vascular dysfunction into a therapeutic opportunity, addressing the root cause rather than just symptoms.
Solution Approach 2:
The patent emphasizes early intervention by identifying vascular changes and capillary dysfunction as early biomarkers that occur before cognitive decline and neuronal damage. By acting on these early vascular changes with blood flow-enhancing compounds, the treatment prevents progression to later stages of disease.
2Object-affected harmful factors
If capillary function is improved to increase cerebral blood flow, then neurodegenerative symptoms are reduced, but the complexity of targeting vascular factors increases treatment development
Solution Approach 1:
The patent develops compounds that simultaneously address multiple vascular and neuroprotective functions through a single molecular mechanism. The compounds improve capillary blood flow, protect against ischemia, and reduce neurodegenerative changes, making the treatment multi-functional and potentially simplifying the therapeutic approach despite the complexity of vascular targeting.
