Beta-Lactam–Cannabinoid Conjugates for Oxidative Stress Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing therapeutics often fail to deliver multiple therapeutic benefits simultaneously through distinct mechanisms of action, and antibiotics like β-lactams can induce oxidative stress leading to cell death, which may not be effectively mitigated.
Innovation Solution
Development of multifunctional conjugate molecules comprising a β-lactam antibiotic and a cannabinoid covalently attached via a linker, where the β-lactam targets its site of action, releasing the cannabinoid to provide additional therapeutic benefits, such as reducing oxidative stress and promoting apoptosis in bacteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If β-lactam antibiotics are used to treat bacterial infections, then antibacterial activity is improved, but oxidative stress is generated leading to harmful effects
Solution Approach 1:
The patent converts the harmful oxidative stress generated by β-lactam antibiotics into a beneficial effect by coupling the antibiotic with a cannabinoid that can modulate the oxidative response. The cannabinoid component mitigates the harmful oxidative stress while the β-lactam maintains its antibacterial activity, thus transforming the harmful byproduct into a therapeutic advantage.
Solution Approach 2:
The patent creates a composite therapeutic molecule by covalently linking a β-lactam antibiotic component with a cannabinoid component through a linker. This composite structure allows the molecule to simultaneously deliver antibacterial activity from the β-lactam and oxidative stress mitigation from the cannabinoid, resolving the contradiction between efficacy and harmful side effects.
2Productivity
If traditional therapeutics are used, then single mechanism of action is provided, but multiple therapeutic benefits cannot be achieved simultaneously
Solution Approach 1:
The patent designs a multifunctional conjugate molecule where a single therapeutic agent performs multiple functions: the β-lactam component provides antibacterial activity by targeting bacterial cell wall synthesis, while the cannabinoid component provides additional therapeutic benefits such as modulating oxidative stress and potentially affecting bacterial membrane integrity. This multi-functionality allows simultaneous delivery of multiple therapeutic benefits through distinct mechanisms of action.
Solution Approach 2:
The patent segments the therapeutic functions into distinct components (β-lactam antibiotic and cannabinoid) that are covalently linked but can be released separately. The β-lactam targets its site of action and releases the cannabinoid, which then provides a second therapeutic benefit. This segmentation allows each component to operate through its own mechanism of action while working together toward multiple therapeutic goals.
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 conjugate molecules deliver dual therapeutic effects by enhancing the antibacterial activity of β-lactams while mitigating oxidative stress and inducing apoptosis, offering a broader spectrum of treatment benefits.
Implementation Method 1
the covalent binding of the β-lactam antibiotic component to its target enables the release of the cannabinoid
Implementation Method 2
the formation of reactive oxygen species (ROS) is a by-product of the normal process of respiration in an oxygen-rich environment
Data Source
AI summary
This disclosure provides multifunctional conjugate molecules in which at least one β-lactam antibiotic is covalently attached to a cannabinoid by means of a linker. The disclosed conjugate molecules are designed to deliver therapeutic benefits as intact molecules, with release of the cannabinoid upon binding of the β-lactam antibiotic to its target conveying further therapeutic benefits, and can be used to treat bacterial infections and other disorders.
