Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbicides lack effective compounds with broad-spectrum herbicidal activity against various weeds in agricultural and horticultural settings.
Innovation Solution
Development of cinnoline derivatives with specific structural features, including heteroaryl moieties and varying substituents, which exhibit enhanced herbicidal activity when applied as active ingredients in agrochemical compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing herbicides are used, then weed control is achieved, but herbicidal activity is insufficient against various weeds
Solution Approach 1:
The patent modifies the chemical structure of cinnoline derivatives by changing parameters such as introducing heteroaryl moieties (R1), varying substituents (R2-R12), and adjusting molecular properties to enhance herbicidal activity and broaden spectrum effectiveness against diverse weeds
Solution Approach 2:
The invention creates composite molecular structures by combining cinnoline core with various heteroaryl groups, substituents, and functional moieties to achieve both high herbicidal activity and broad-spectrum coverage simultaneously
2Reliability
If novel cinnoline derivatives are developed, then herbicidal efficacy is improved, but compound complexity increases
Solution Approach 1:
The patent divides the complex molecule into functional segments: cinnoline core, heteroaryl moieties (R1), substituent groups (R2-R12), and identifies key pharmacophores responsible for herbicidal activity, allowing systematic optimization of each segment
Solution Approach 2:
The cinnoline derivative framework is designed to be multi-functional, where the core structure combined with specific substituents can target multiple weed types and mechanisms, reducing the need for entirely separate compounds for different applications
