Aromatic Carboxamide Derivatives for Parasite Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parasiticides are ineffective in exterminating certain animal parasites, necessitating a composition with enhanced parasiticidal activity.
Innovation Solution
A composition containing aromatic carboxamide derivatives, specifically represented by Formula (1), which includes phenyl groups, halogen atoms, and heptafluoroisopropyl groups, is developed to effectively exterminate animal parasites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional parasiticides (imidacloprid, fipronil) are used, then they can control some pests, but they are ineffective against certain animal parasites
Solution Approach 1:
The patent modifies the chemical structure of conventional parasiticides by introducing specific substituents (halogen atoms at positions Y1, Y5; heptafluoroisopropyl group at Y3; phenyl groups at Q1) to enhance parasiticidal activity against previously resistant parasites while maintaining effectiveness against target pests
Solution Approach 2:
The invention creates a composite molecular structure combining multiple functional groups (amide derivatives with specific aromatic substitutions) to achieve broad-spectrum parasiticidal activity that encompasses both insect control and anti-parasite effectiveness
2Reliability
If existing amide derivatives are used for pest control, then they show insecticidal activity, but they lack demonstrated parasiticidal activity
Solution Approach 1:
The patent introduces specific local substitutions on the aromatic rings (halogen atoms at Y1, Y5 positions and heptafluoroisopropyl group at Y3 position) to confer parasiticidal activity while maintaining the core amide derivative structure for insecticidal function

AI summary
A compositon for exterminating an animal parasite comprising as an active ingredient at least one amide derivative represented by the following Formula (1) has an excellent activity exterminating an animal parasite: In the following Formula (1), X1 represents a fluorine atom; X2, X3, and X4 are each a hydrogen atom; R1 represents a hydrogen atom or a C1-C3 alkyl group; R2 is a hydrogen atom; Y1 and Y5 each independently represent a halogen atom or a C1-C3 haloalkyl group; Y2 and Y4 each represent a hydrogen atom; and Y3 represents a heptafluoroisopropyl group.
