Hookworm infection is a leading cause of maternal and child morbidity in countries of the tropics and subtropics, as well as being an important parasite in companion-animal medicine. The cyclotides are a novel family of cyclic cystine knot containing peptides from plants that have been shown to possess anthelmintic activity against Haemonchus contortus and Trichostrongylus colubriformis, two important gastrointestinal nematodes of sheep. In the current study we demonstrated the in vitro effects of three representative cyclotides, kalata B1, kalata B6 and cycloviolacin O14, on the viability of larval and adult life stages of the dog hookworm Ancylostoma caninum, and larvae of the human hookworm Necator americanus. The cyclotides showed significant anthelmintic activity towards both hookworm species. The different cyclotides showed similar patterns of relative activity as that seen previously with the livestock nematode species. This study demonstrates that cyclotides have promising activity in vitro against important parasites of companion animals and humans.
