Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for degenerative diseases associated with mitochondrial damage and dysfunction, such as Parkinson's and Alzheimer's, are limited in efficacy and safety, with existing metabolic cofactors like Coenzyme Q and vitamins providing occasional benefits but lacking general utility in clinical practice.
Innovation Solution
Development of compounds of formula I, specifically designed to protect against calcium- and oxidative-stress mediated damage to mitochondrial function, which are used in pharmaceutical compositions for treating degenerative diseases and disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing metabolic cofactors like Coenzyme Q and vitamins are used for treatment, then occasional benefits are provided, but general utility and efficacy are limited
Solution Approach 1:
The patent modifies the chemical structure of coenzyme Q by changing parameters such as the side chain length, aromatic ring substitutions, and ester groups to create analogs with improved mitochondrial protective activity while maintaining the core quinone structure responsible for biological function
Solution Approach 2:
The invention creates composite molecular structures combining the quinone core of coenzyme Q with various aromatic substituents and side chains to produce compounds that exhibit enhanced stability, reduced oxidation, and improved therapeutic efficacy compared to natural coenzyme Q
2Use of energy by moving object
If mitochondria produce ATP through oxidative phosphorylation, then energy is generated, but reactive oxygen species are simultaneously produced causing cellular damage
Solution Approach 1:
The patent employs compounds containing quinone and hydroquinone groups that can reversibly accept and donate electrons, thereby converting the harmful reactive oxygen species into less harmful molecules while maintaining the mitochondrial energy production process
Solution Approach 2:
The invention uses compounds with redox-active quinone/hydroquinone groups as intermediary substances that mediate between the electron transport chain and reactive oxygen species, providing electron sinks that prevent ROS formation without disrupting ATP synthesis
3Stability of the object's composition
If mitochondrial DNA remains unprotected within the mitochondrial membrane, then mitochondrial function is maintained, but mtDNA is easily damaged by free radicals and ROS
Solution Approach 1:
The patent utilizes the quinone/hydroquinone redox couple to convert harmful oxidizing conditions into protective reducing environments, thereby protecting mtDNA from oxidative damage while preserving mitochondrial function
Solution Approach 2:
The invention employs compounds that preemptively scavenge free radicals and reactive oxygen species before they can damage mtDNA, providing a protective buffer that cushions the mitochondrial genome against oxidative stress
