Insecticide discovery-"Chance favors the prepared mind"

Area of Science:

• Agricultural Science
• Entomology
• Chemical Biology

Background:

• Growing global population necessitates enhanced food production, requiring new pest insect control solutions.
• Existing insecticides face challenges due to resistance and stringent safety regulations, demanding novel chemistries and modes of action.
• The discovery of new insecticidal active ingredients (AIs) is vital for sustainable agriculture.

Purpose of the Study:

• To analyze historical and current approaches for discovering first-in-class (FIC) insecticides.
• To identify the most successful strategies for identifying novel insecticidal compounds.
• To provide insights for future insecticide discovery efforts.

Main Methods:

• Review of literature and industry practices in insecticide discovery.
• Analysis of case studies of first-in-class insecticide development.
• Evaluation of different discovery approaches, including modification of existing products and de novo design.

Main Results:

• Historically, most insecticides are derived from existing molecules, but first-in-class (FIC) compounds represent significant innovation.
• Understanding the origins of FIC insecticides reveals key successful discovery strategies.
• Diverse approaches are employed, with varying degrees of success in identifying novel insecticidal AIs.

Conclusions:

• First-in-class (FIC) insecticides serve as crucial prototypes for future advancements in efficacy, safety, and spectrum.
• Analyzing successful discovery pathways for FIC compounds offers valuable guidance for the agrochemical industry.
• Strategic approaches to insecticide discovery are essential for addressing pest resistance and ensuring food security.
