Bicyclic Pyrazole Compounds for Resistant Bacterial Infections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antibacterial agents are ineffective against resistant microbes, such as methicillin-resistant Staphylococcus aureus, due to mechanisms like antibiotic inactivation, efflux pumps, and target modification, leading to limited clinical options and increasing treatment costs and health risks.
Innovation Solution
Development of pyrazole compounds with a specific B-containing bicyclic ring system and fused pyrazole moiety, which act as inhibitors of bacterial growth, offering a new class of antibacterial agents effective against a range of pathogenic microorganisms, including resistant strains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing antibacterial agents are used, then they can treat common bacterial infections, but they become ineffective against resistant microbes such as MRSA
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of antibacterial agents through the bicyclic pyrazole compound design, changing molecular parameters such as ring system configuration, heteroatom placement, and substituent patterns to create new compounds with enhanced activity against resistant bacteria while maintaining efficacy against common strains
Solution Approach 2:
The invention employs composite materials by combining multiple structural elements into a single bicyclic pyrazole framework, integrating a pyrazole ring with a second ring containing specific heteroatoms (N, O, or S) at defined positions, creating a composite molecular structure that achieves broad-spectrum activity including against MRSA
2Reliability
If new antibacterial agents are developed to overcome resistance, then efficacy against resistant strains improves, but development time and costs increase
Solution Approach 1:
The patent applies preliminary action by providing a predetermined framework of bicyclic pyrazole compounds with specific structural parameters and substitution patterns that have been pre-designed to target resistant bacteria, allowing researchers to systematically explore structure-activity relationships and accelerate the development process rather than starting from scratch
Solution Approach 2:
The invention applies segmentation by dividing the antibacterial compound into distinct structural segments - the core bicyclic pyrazole framework and variable substituent groups - allowing independent optimization of different portions of the molecule to achieve both resistance overcoming and reduced development complexity
