Developing novel anthelmintics from plant cysteine proteinases

Area of Science:

• Parasitology
• Natural Product Chemistry
• Drug Discovery

Background:

• Intestinal helminth infections pose significant threats to livestock and human health.
• Existing synthetic anthelmintics face widespread resistance in livestock nematodes and emerging unresponsiveness in human hookworms.
• The development pipeline for novel synthetic anthelmintics is slow, with no new modes of action expected soon.

Purpose of the Study:

• To review the potential of cysteine proteinases from fruits and plant latices as novel anthelmintic agents.
• To discuss the challenges associated with translating laboratory findings and traditional medicine knowledge into marketable products.
• To highlight the untapped potential of natural compounds for combating helminth infections.

Main Methods:

• Literature review of current research on cysteine proteinases as anthelmintics.
• Analysis of challenges in the development and commercialization of natural product-derived medicines.
• Exploration of traditional and folk medicine knowledge related to plant-based anthelmintics.

Main Results:

• Cysteine proteinases show promise as a new class of anthelmintics.
• Significant hurdles exist in developing natural products, including standardization, efficacy, and safety.
• Folk medicine and laboratory research indicate a rich source of undiscovered anthelmintic compounds in nature.

Conclusions:

• Plant-derived cysteine proteinases represent a promising avenue for novel anthelmintic drug development.
• Overcoming developmental and regulatory challenges is crucial for realizing the therapeutic potential of these natural compounds.
• Further research and investment are needed to harness the vast potential of natural products for human and veterinary medicine.
