Triazine Herbicidal Compounds for Weed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current herbicidal derivatives do not effectively address the need for compounds with good herbicidal activity against undesirable plant growth, particularly weeds, in crops.
Innovation Solution
The development of triazine derivatives of formula (I), which exhibit surprisingly good herbicidal activity, including compounds like Methyl 2-[[2-chloro-5-(3,5-dimethyl-2,6-dioxo-4-thioxo-1,3,5-triazinan-1-yl)-4-fluoro-benzoyl]amino]acetate, formulated into agrochemical compositions for effective weed control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicidal derivatives are used, then herbicidal activity is provided, but the activity is insufficient against undesirable plant growth and weeds
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of triazine derivatives through systematic variation of substituents at positions R1-R15, creating a series of analogs with improved herbicidal activity. The core triazine ring structure is maintained while changing parameters such as alkyl groups, halogen atoms, and functional groups to optimize effectiveness against undesirable plants.
Solution Approach 2:
The invention creates composite herbicidal compounds by combining the triazine core structure with various substituent groups (R1-R15) to form new chemical entities. These composite structures integrate multiple functional groups that work synergistically to enhance herbicidal activity and broaden spectrum of control.
2Reliability
If new triazine derivatives are developed to improve herbicidal efficacy, then control of undesirable plant growth is enhanced, but the complexity of compound structure increases
Solution Approach 1:
The complex herbicidal compound is segmented into a recognizable triazine core structure with modular substituent groups (R1-R15). This segmentation allows the core pharmacophore to be maintained while permitting systematic modification of peripheral groups to optimize activity without completely redesigning the molecular framework.
Solution Approach 2:
The triazine core structure serves as a universal platform that can accommodate multiple different substituent patterns while maintaining herbicidal activity. This multi-functional core allows a single structural framework to provide broad-spectrum weed control through various substituent combinations.
