Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for neurodegenerative diseases like Parkinson's and Alzheimer's are limited, often providing only temporary relief and are associated with significant side effects due to the 'one-drug, one-target' approach, which is insufficient for the complex nature of these diseases.
Innovation Solution
Development of compounds with multiple mechanisms of action that integrate monoamine oxidase inhibition, cholinesterase inhibition, and free radical scavenging capabilities, designed to provide neural protection and treat related diseases more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple drugs are used in combination therapy to target different pathways, then the treatment effectiveness is improved, but the device complexity and side effects increase
Solution Approach 1:
The patent combines multiple pharmacophores (MAO inhibitor, AChE inhibitor, and free radical scavenger moieties) into a single multifunctional compound molecule. This merging approach integrates the therapeutic actions of multiple drugs into one molecule, achieving synergistic effects while simplifying the treatment regimen and reducing the complexity associated with combination therapy.
Solution Approach 2:
The invention creates a universal compound that performs multiple functions simultaneously: inhibiting monoamine oxidase, inhibiting acetylcholinesterase, and scavenging free radicals. This multi-functional molecule addresses multiple pathological mechanisms of neurodegenerative diseases through a single agent, improving treatment effectiveness without requiring multiple separate medications.
2Object-generated harmful factors
If a single drug targets one specific pathway, then the side effects are reduced, but the treatment effectiveness for complex diseases is insufficient
Solution Approach 1:
The patent designs a single multifunctional compound that simultaneously targets multiple pathways involved in neurodegenerative diseases: MAO inhibition for neurotransmitter regulation, AChE inhibition for cholinergic enhancement, and free radical scavenging for oxidative stress protection. This multi-functional approach maintains the simplicity of single-drug administration (reducing side effects) while achieving comprehensive disease coverage (improving effectiveness).
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These compounds offer enhanced medical effects with reduced side effects by targeting multiple pathways, potentially leading to more effective prevention and treatment of neurodegenerative diseases and oxidative stress-related conditions.
Implementation Method 1
Monoamine oxidases (MAO) are enzymes to catalyze amines in oxidative deamination reaction of monoamines
Implementation Method 2
acetyl cholinesterase inhibitors (AChEI), mainly through reversible inhibition of acetylcholinesterase, may reduce the speed of acetylcholine degradation
Implementation Method 3
antioxidants, such as vitamin E and some other free radical scavengers, can prevent the damage of Aβ to neurons
