Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides lack effective compounds with broad-spectrum herbicidal activity and stability for agricultural applications.
Innovation Solution
Development of cinnoline derivatives with specific heteroaryl substituents and functional groups, such as halogen, cyano, and alkyl groups, which exhibit herbicidal activity when applied in agrochemical compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicides are used, then some herbicidal activity is achieved, but broad-spectrum herbicidal activity and stability for agricultural applications are insufficient
Solution Approach 1:
The patent modifies the chemical structure of cinnoline derivatives by changing parameters such as substituting heteroaryl groups (pyridyl, pyrimidyl, triazolyl) at the 1-position and introducing various functional groups (cyano, carbonyl, carboxylate) at the 5-position. These structural parameter changes result in enhanced herbicidal activity across a broad spectrum of weed types while maintaining stability for agricultural applications.
Solution Approach 2:
The invention creates composite molecular structures by combining the cinnoline core with diverse heteroaryl substituents and functional groups. This composite approach allows the herbicide to interact with multiple target sites in different weed species, achieving broad-spectrum activity while maintaining reliable herbicidal effect.
2Reliability
If cinnoline derivatives with specific substituents are developed, then herbicidal activity is improved, but compound complexity increases
Solution Approach 1:
The patent divides the cinnoline derivative molecule into distinct functional segments: the core cinnoline structure, heteroaryl substituent groups (pyridyl, pyrimidyl, triazolyl) at the 1-position, and functional groups (cyano, carbonyl, carboxylate) at the 5-position. This segmentation allows each part to contribute specific properties, achieving high herbicidal activity while maintaining manageable structural complexity through modular design.
