Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for increasing glutathione (GSH) levels in the body are inadequate, particularly under conditions of high oxidative demand or when normal supplies are insufficient, leading to cellular oxidation and associated diseases.
Innovation Solution
Administration of pharmaceutical GSH, which is safe, stable, and rapidly bioavailable, helps maintain intracellular GSH levels, supporting immune responses, neutralizing reactive intermediates, and curbing viral replication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If normal GSH supply mechanisms are relied upon, then physiological GSH levels are maintained under normal conditions, but GSH levels become insufficient under conditions of high oxidative demand or when distribution is inadequate
Solution Approach 1:
The patent uses S-adenosylmethionine (SAM) as an intermediary substance that the body converts into GSH. Rather than administering GSH directly (which has poor oral bioavailability), SAM serves as a stable precursor that mediates the production of active GSH within cells, bypassing the limitations of direct GSH administration and ensuring reliable GSH supply under various conditions.
Solution Approach 2:
The patent changes the chemical parameter from administering GSH directly to administering SAM, a different compound that the body metabolizes into GSH. This parameter change (from GSH to SAM precursor) resolves the bioavailability and stability issues while ensuring adequate GSH levels are achieved reliably under both normal and high oxidative demand conditions.
2Reliability
If GSH is administered to increase intracellular levels, then oxidative stress is reduced and immune responses are enhanced, but the stability and bioavailability of administered GSH are insufficient
Solution Approach 1:
The patent applies preliminary action by administering SAM before the body needs GSH. SAM is a stable compound that is stored and then converted into GSH when needed. This preliminary provision of the precursor ensures that GSH is produced in situ when required, bypassing the stability and bioavailability problems of administering GSH directly.
Solution Approach 2:
SAM acts as a stable intermediary that the body converts into GSH. This intermediary approach allows the stable SAM compound to be administered, which then transforms into the active GSH form within the body, ensuring both stability during administration and effectiveness when needed.
3Ease of operation
If oral GSH administration is attempted, then convenience of administration is improved, but absorption and bioavailability are significantly reduced
Solution Approach 1:
The patent uses SAM as an intermediary that can be orally administered and then converted to GSH. SAM has much better oral bioavailability than GSH itself, allowing convenient oral administration while still achieving the desired intracellular GSH levels through metabolic conversion.
Solution Approach 2:
The patent changes the administered substance from GSH to SAM, fundamentally altering the chemical parameter to one that is stable and well-absorbed orally. This parameter change maintains the ease of oral administration while dramatically improving the quantity of bioavailable GSH through the body's natural conversion processes.
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
GSH therapy effectively replenishes intracellular levels, enhancing immune responses, reducing oxidative stress, and decreasing morbidity and mortality from viral infections and other conditions associated with GSH deficiency.
Implementation Method 1
rapidly bioavailable
Implementation Method 2
Glutathione may be transported through membranes by the sodium-dependent glutamate pump
Implementation Method 3
GSH functions directly or indirectly in many important biological phenomena... protection of cells from free-radical mediated damage
Implementation Method 4
The ubiquitous tripeptide L-glutathione (GSH)... is a well-known biological antioxidant
Implementation Method 5
Loss of activity of glutathione peroxidase 4 (GPX4) in a process called ferroptosis, leads to accumulation of lipid-based reactive oxygen species (ROS), particularly lipid hydroperoxides
Implementation Method 6
Loss of activity of glutathione peroxidase 4 (GPX4)... leads to accumulation of lipid-based reactive oxygen species

AI summary
The use of glutathione to treat or prophylax viral, bacterial, chemical, and nuclear agents, or to treat or prophylax radiation injury to humans due to release of radioactive elements. The preferred formulation is an oral dosage form, with reduced glutathione stabilized by ascorbic acid, packaged to under controlled humidity and temperature conditions to ensure creation of charge transfer complexes that ensure consistent packaging, insignificant oxidation during packaging and subsequent normal storage, and high oral bioavailability for humans.
