Target-based and whole-worm screening approaches to anthelmintic discovery

Area of Science:

• Parasitology
• Drug Discovery
• Molecular Biology

Background:

• Anthelmintic drug discovery relies on target-based and whole-worm screening.
• Nematode intestine and external layers are key potential drug targets.
• Understanding drug modes of action is crucial for developing new treatments.

Purpose of the Study:

• To review experimental approaches for identifying novel anthelmintics.
• To highlight the significance of nematode intestine and external layers as drug targets.
• To exemplify target-based drug discovery using the ecdysone signaling pathway.

Main Methods:

• Review of target-based screening assays and in silico drug design.
• Utilizing whole-worm assays to identify anthelmintic agents.
• Analysis of recent literature on nematode ecdysone signaling pathway receptors.

Main Results:

• Disruption of nematode intestine and external layers by specific anthelmintics demonstrates their potential as drug targets.
• Whole-worm screening identified anthelmintic activity in agents with known insect activity.
• Ecdysone signaling pathway receptors in nematodes offer a model for target-based screening.

Conclusions:

• Both target-based and whole-worm screening are valuable for anthelmintic discovery.
• Targeting nematode-specific structures like the intestine and external layers is a promising strategy.
• Further research into specific molecular targets can advance high-throughput drug screening.
