Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for strokes are limited, with no specific therapy available and existing treatments like tPA having a short therapeutic window and being ineffective for hemorrhagic strokes, posing a significant public health challenge.
Innovation Solution
A therapeutic active ingredient comprising polylysine compounds such as Coenzyme Q10-Polylysine, Retinoic Acid-Polylysine, Cysteine-Polylysine, Taurine-Polylysine, and Glutathione-Polylysine, which acts to control free radical and immunological mechanisms, reduce inflammation, and create a favorable environment for cell repair, thereby preventing and treating stroke-related inflammatory phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tPA is used for stroke treatment, then clot dissolution is achieved, but the therapeutic window is very short (limited to a few hours after stroke)
Solution Approach 1:
The patent divides stroke treatment into two distinct phases: (1) acute phase focusing on clot dissolution and reperfusion, and (2) inflammatory phase focusing on neuroprotection and tissue repair. This segmentation allows different therapeutic strategies to be applied at different time points, extending the overall treatment window beyond the limited few hours when tPA can be administered.
Solution Approach 2:
The patent employs preliminary protective actions by administering antioxidants and anti-inflammatory agents before the inflammatory phase fully develops. This preliminary action prevents secondary brain damage from oxidative stress and inflammation, addressing the time limitation of tPA by preparing the brain for reperfusion and protecting vulnerable tissue ahead of time.
2Reliability
If tPA is used for ischemic stroke treatment, then clot dissolution is achieved, but it has no effect on inflammatory, edematous and immune processes
Solution Approach 1:
The patent creates a multi-functional therapeutic approach where the treatment regimen addresses multiple pathological processes: clot dissolution (tPA), oxidative stress (antioxidants like vitamin C, E, and glutathione), inflammation (anti-inflammatory agents), and immune modulation. This universal approach covers all major aspects of stroke pathology within a single integrated treatment protocol.
Solution Approach 2:
The patent uses a composite therapeutic strategy combining multiple agents with different mechanisms of action: thrombolytics for clot breakdown, antioxidants for free radical scavenging, anti-inflammatory agents for cytokine suppression, and neuroprotective compounds. This composite approach ensures comprehensive coverage of the complex pathological processes involved in stroke.
3Reliability
If tPA is administered, then reperfusion is achieved, but it cannot be used in hemorrhagic strokes
Solution Approach 1:
The patent introduces protective intermediary agents (antioxidants and anti-inflammatory compounds) that mediate between reperfusion and tissue damage. These intermediaries scavenge free radicals and reduce oxidative stress that would otherwise cause damage during reperfusion, making the treatment safe for both ischemic and hemorrhagic stroke types by preventing secondary injury mechanisms.
4Reliability
If conventional stroke treatment is used, then acute phase management is addressed, but preventive and healing solutions for long-term outcomes are insufficient
Solution Approach 1:
The patent establishes continuous protective action by administering antioxidants and anti-inflammatory agents throughout the inflammatory phase and into the recovery period. This continuous therapy maintains reduced oxidative stress and inflammation levels, protecting the brain during the extended period when repair processes are active, thereby extending therapeutic benefits from the acute phase into long-term recovery.
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
The active ingredient effectively neutralizes free radicals, reduces oxidative stress, and promotes brain repair by regulating immune activation and reducing neurotoxic molecules, offering a more effective and applicable solution for stroke prevention and treatment than existing therapies.
Implementation Method 1
The active ingredient is effective in humans and animals to prevent strokes and/or to treat the inflammatory phase following a stroke... control the free radical, immunological and degenerative mechanisms of strokes
Implementation Method 2
The active ingredient according to the invention has in particular an anti-inflammatory effect on lesions located in the brain... limits the release of pro-inflammatory cytokines that release microglia
