Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Penicillin G solutions are unstable at varying temperatures and pH levels, leading to rapid degradation and the formation of undesirable side effects, limiting their storage duration and effectiveness as an antibiotic.
Innovation Solution
A composition comprising malic acid, caffeic acid, flavan-3-ols, anthocyanins, and optionally other phenolic compounds, which stabilizes alkali salts of penicillin G, allowing for extended storage and use as a dietary supplement and therapeutic agent, including for cancer treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If alkali salts of penicillin G are used to improve water solubility, then solubility is improved, but stability at varying pH and temperature deteriorates
Solution Approach 1:
The patent introduces a buffer system comprising malic acid, caffeic acid, flavan-3-ols, and anthocyanins as intermediary substances that mediate between the penicillin G and the varying pH/temperature conditions. These buffer components maintain a stable pH environment (particularly around pH 3-4) and provide thermal stability, allowing penicillin G to remain stable in aqueous solution without requiring extreme storage conditions.
2Ease of operation
If penicillin G is stored at room temperature for extended periods, then convenience is improved, but degradation increases
Solution Approach 1:
The patent changes the chemical parameters of the solution by adding specific buffer components (malic acid, caffeic acid, flavan-3-ols, anthocyanins) that alter the pH stability and thermal resistance parameters. This allows the penicillin G solution to maintain its antibacterial efficacy at room temperature for extended periods (up to several weeks) without significant degradation, transforming the storage conditions from requiring refrigeration to allowing ambient storage.
3Duration of action of stationary object
If penicillin G solution is stabilized with conventional methods, then storage time is extended, but degradation products causing allergies may still form
Solution Approach 1:
The patent converts the potentially harmful degradation process into a beneficial outcome by using the buffer components to control and direct the stability mechanism. The malic acid, caffeic acid, flavan-3-ols, and anthocyanins work synergistically to maintain pH stability and prevent the formation of harmful degradation products like penicilloic acid and penicillenic acid, while still allowing extended storage. The buffer system essentially transforms the unstable degradation pathway into a stable preservation mechanism.
