Orco Ion Channel Modulators for Insect Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling insect-borne diseases and agricultural pest management, such as insecticides and biological larviciding, have limitations including environmental toxicity, limited duration, and high costs, with a scarcity of compounds that effectively inhibit insect olfactory sensing.
Innovation Solution
Development of compounds that bind to and modulate insect Orco ion channels, disrupting olfactory processes critical for host-targeting behaviors in insects like mosquitoes, using specific chemical structures and carriers to mediate Orco responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insecticides are used to kill or repel insects, then insect control effectiveness is improved, but environmental and host toxicity increases
Solution Approach 1:
The patent uses Orco ion channel modulators as intermediary compounds that specifically target the insect olfactory system rather than acting as broad-spectrum neurotoxins. These compounds bind to the Orco receptor subunit, which is essential for odorant signal transduction in insects, thereby disrupting host-seeking behavior without the widespread toxicity of traditional insecticides.
Solution Approach 2:
The invention changes the mode of action parameter from direct neural inhibition (traditional insecticides) to olfactory signal disruption (Orco modulators). By targeting the specific parameter of odorant receptor function rather than general neural activity, the compounds achieve insect control with reduced toxicity profiles.
2Object-affected harmful factors
If biological larviciding is used to avoid toxicity issues, then environmental safety is improved, but treatment time and cost increase
Solution Approach 1:
The patent replaces biological systems (natural predators, parasitoids) with chemically-defined Orco ion channel modulators. These synthetic or semi-synthetic compounds act directly on the insect olfactory system, providing a non-biological solution that maintains environmental safety while reducing treatment time and cost.
3Reliability
If compounds that inhibit insect sensing are developed, then insect behavior disruption is improved, but scarcity of such compounds limits availability
Solution Approach 1:
The patent targets the Orco ion channel, which is a universal receptor subunit shared across all insect odorant receptor complexes. By developing compounds that bind to this conserved target, the invention creates multi-functional inhibitors that can disrupt olfactory sensing in diverse insect species, thereby increasing the availability and applicability of sensing inhibition compounds.
