Enzymatic Lung Biocide Generation for Antibiotic Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating respiratory infections, such as pneumonia, are ineffective against antibiotic-resistant bacteria and do not provide a means to deliver enzymatic activity directly to the respiratory tract to combat infection and inflammation.
Innovation Solution
A therapeutic composition comprising an oxidoreductase enzyme that produces hydrogen peroxide and a peroxidase enzyme, along with a salt that reacts with hydrogen peroxide to form a biocide, is delivered to the lungs using an aqueous or non-aqueous medium, allowing for the generation of a therapeutically effective concentration of biocide within the respiratory tract.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antibiotics are used to treat respiratory infections, then bacterial infections can be controlled, but antibiotic-resistant bacteria emerge and render treatments ineffective
Solution Approach 1:
The patent converts hydrogen peroxide, which can be harmful at high concentrations, into a beneficial therapeutic agent by using peroxidase enzymes to generate it in situ within the lungs. The enzyme system transforms this potentially damaging substance into a controlled biocidal agent that kills bacteria without contributing to antibiotic resistance, effectively converting a harmful factor into a therapeutic benefit.
Solution Approach 2:
The patent introduces peroxidase enzymes as intermediary agents that facilitate the generation of hydrogen peroxide from oxygen and hydrogen donors within the lung tissue. These enzymes act as mediators between available substrates and the desired biocidal effect, enabling localized production of therapeutic concentrations of hydrogen peroxide without requiring direct administration of the peroxide itself.
2Ease of operation
If enzymatic treatment is delivered systemically, then the enzymes can reach the respiratory tract, but the complexity of delivery and achieving effective concentrations increases
Solution Approach 1:
The patent segments the enzymatic treatment into multiple components: peroxidase enzymes, hydrogen donors (substrates), and oxygen sources. These segmented components can be administered separately or in combination, allowing flexibility in delivery routes (inhalation, injection, topical application) and simplifying the overall delivery system while ensuring the enzymes reach the respiratory tract at effective concentrations.

Function Achieved in This Case
The composition effectively treats lung diseases and conditions by generating biocides within the lungs, addressing antibiotic-resistant infections and inflammation, and can be administered via a ventilator, vaporizer, or nebulizer for targeted delivery.
Implementation Method 1
an oxidoreductase enzyme that produces hydrogen peroxide by catalyzing the oxidation of a substrate
Implementation Method 2
a peroxidase enzyme that catalyzes a reaction between hydrogen peroxide and a salt that acts as an oxygen acceptor and is capable of reacting with hydrogen peroxide to form a biocide

AI summary
A therapeutic composition for the treatment of lung diseases or disorders and diseases or disorders of the airway passages including pneumonia, acute respiratory failure, and acute respiratory distress syndrome is based on the generation of a biocidal anion by an enzymatic reaction catalyzed by a peroxidase. The peroxide utilized by the peroxidase enzyme can be endogenous or can be generalized by the action of an oxidase enzyme on a suitable substrate.
