Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an unmet need for new forms of Aramchol with desirable physicochemical properties, particularly increased solubility and bioavailability, to effectively treat fatty liver disease and Non-Alcoholic SteatoHepatitis (NASH).
Innovation Solution
The development of salts of Aramchol with amino alcohols, amino sugars, or amino acids, such as N-methylglucamine, lysine, and tromethamine salts, which exhibit improved solubility, absorption, and bioavailability, allowing for lower dosing and easier processing into pharmaceutical formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Aramchol free acid is used, then the compound has the required therapeutic activity, but the solubility and bioavailability are insufficient
Solution Approach 1:
The patent applies parameter changes by converting Aramchol free acid into different salt forms (sodium salt, potassium salt, magnesium salt, calcium salt, aluminum salt, zinc salt, manganese salt, iron salt, copper salt, cobalt salt, nickel salt, lithium salt, ammonium salt, and organic amine salts). This chemical parameter change transforms the compound's physicochemical properties, specifically improving solubility and bioavailability while preserving the core therapeutic activity of the aramchol molecule.
2Device complexity
If Aramchol free acid is used, then the compound structure is simple, but the absorption and exposure are limited
Solution Approach 1:
The patent changes the chemical parameter of the Aramchol compound by forming salts with various cations. This transformation maintains the relatively simple molecular structure while dramatically improving absorption and exposure characteristics, as evidenced by the increased solubility and bioavailability observed in the salt forms compared to the free acid.
3Ease of manufacture
If Aramchol free acid is used, then the formulation processing is straightforward, but the flow properties are inadequate
Solution Approach 1:
The patent applies parameter changes by converting Aramchol into salt forms, which fundamentally alters the physical properties of the compound. The salt forms exhibit improved flow properties compared to the free acid, making them more suitable for formulation processing into solid dosage forms while maintaining ease of manufacture.
