Amide Compounds for Blood Lipid Regulation and Gallstone Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lipid-lowering medications, such as statins, while effective in reducing atherosclerosis and coronary disease, often come with side effects like impaired liver function and muscular pain, necessitating the development of new drugs with improved efficacy and reduced toxicity.
Innovation Solution
The development of novel amide compounds formed by linking amine and carboxylic acid compounds through a covalent bond, which effectively regulate blood lipid levels and prevent cholelithiasis with low toxicity, reducing triglycerides and cholesterol levels, and inhibiting the formation of gallstones in animal models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If statins are used for long-term dosing to reduce cholesterol and prevent atherosclerosis, then the efficacy in lowering blood lipid is improved, but side effects such as impaired liver function, muscular pain, and increased aminotransferases occur
Solution Approach 1:
The patent modifies the chemical structure of statins by replacing the hydroxyl group with various substituents (R1-R8 groups including phenyl, alkyl, heterocyclic radicals) to create novel amide compounds that maintain cholesterol-lowering efficacy while reducing hepatotoxicity and muscular side effects
Solution Approach 2:
The invention creates composite molecular structures by combining amine compounds and carboxylic acid compounds through covalent bonds to form new amide compounds with improved pharmacological properties, integrating beneficial features while eliminating harmful effects
2Object-affected harmful factors
If new lipid-lowering drugs are developed to reduce side effects, then toxicity is reduced, but the complexity of drug development and clinical validation increases
Solution Approach 1:
The patent systematically segments the statin molecular structure into functional components (core structure, side chains R1-R8) and independently optimizes each segment to reduce toxicity while maintaining efficacy, allowing modular drug development approach
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
These compounds demonstrate significant blood lipid-lowering effects, including reduced cholesterol and low-density lipoprotein levels, while also preventing gallstone formation with minimal toxicity, offering a safer alternative to existing treatments.
Implementation Method 1
Amine compounds and carboxylic acid compounds are linked by covalent bond of ester and amide
