Pyridone Herbicidal Derivatives for Selective Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides do not effectively address the need for selective and efficient weed control in agricultural and horticultural settings, particularly in crops of useful plants.
Innovation Solution
Development of novel pyridone derivatives with specific structural variations, including substituents such as C1-C6alkyl, C1-C6alkoxy, C2-C6alkenyl, and heteroaryl groups, which exhibit enhanced herbicidal activity when applied as agrochemical compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicides are used, then weed control is provided, but the herbicidal activity is insufficient and selectivity is poor
Solution Approach 1:
The patent applies parameter changes by systematically varying the chemical structure of pyridone derivatives through different substituents (R1-R11) and heteroatom configurations (X, n). This structural parameter optimization enables enhanced herbicidal activity while achieving crop selectivity, directly resolving the contradiction between effectiveness and selectivity.
Solution Approach 2:
The invention employs local quality by introducing specific functional groups and heteroatoms at particular positions within the pyridone molecular structure. These localized structural modifications (e.g., specific R groups, X substitutions) create regions of enhanced biological activity while maintaining overall molecular compatibility with crop safety requirements.
2Reliability
If novel pyridone derivatives are developed, then herbicidal activity is enhanced, but the structural complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the pyridone molecule into distinct functional regions (R1-R11 substituents, heteroaryl groups, X positions) that can be independently optimized. This modular approach allows systematic enhancement of herbicidal activity through targeted structural modifications without creating unmanageable complexity.
Solution Approach 2:
The invention achieves universality by designing a core pyridone structure that can accommodate multiple different substituent types and configurations. This versatile scaffold enables a single molecular framework to provide enhanced herbicidal activity across different weed species while maintaining structural manageability through standardized substitution patterns.
