Substituted Amide Urea Derivatives Inhibit Rho Kinase
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for cardiovascular diseases, cancer, neurological diseases, renal diseases, bronchial asthma, erectile dysfunction, and glaucoma are inadequate, with many patients experiencing uncontrolled hypertension and resistance to existing medications, highlighting the need for new therapeutic options that effectively target Rho kinase activity.
Innovation Solution
Development of substituted amide and urea derivatives that inhibit Rho kinase activity, which can be administered to patients to treat a range of diseases associated with Rho kinase activation, including hypertension, atherosclerosis, and smooth muscle hyperreactivity disorders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing treatments are used for cardiovascular diseases and hypertension, then current standard therapy is provided, but treatment effectiveness is inadequate and many patients experience uncontrolled hypertension and resistance to medications
Solution Approach 1:
The patent introduces a novel chemical compound with a specific molecular structure (substituted amide and urea derivatives) that targets Rho kinase with different pharmacological parameters than existing medications. This structural parameter change enables the compound to overcome treatment resistance by providing a new mechanism of action that is effective in patients who have failed standard therapies.
2Reliability
If new Rho kinase inhibitor compounds are developed, then treatment effectiveness for resistant patients is improved, but drug development complexity and time are increased
Solution Approach 1:
The patent presents a series of related compounds with systematic structural variations (different substituents at various positions on the molecular framework). This segmented approach allows for structure-activity relationship studies where individual structural elements can be optimized independently, reducing overall development complexity by breaking down the molecular design into manageable segments.
Solution Approach 2:
The core molecular framework of the substituted amide and urea derivatives serves as a universal structure that can target Rho kinase activity across multiple disease indications including hypertension, cardiovascular diseases, and other Rho kinase-mediated conditions. This multi-functionality reduces development complexity by creating a single compound class that addresses multiple therapeutic needs.
