A series of novel 2-alkoxy- and 2-aryloxyiminoalkyl trifluoromethanesulfonanilide derivatives have shown significant in vitro parasiticidal activity against the ectoparasites Ctenocephalides felis and Rhipicephalus sanguineus. A number of these compounds also displayed significant in vitro endoparasite activity against the nematode Haemonchus contortus.
- Ctenocephalides felis (cat flea)
- Haemonchus contortus
- Oxime ether
- Rhipicephalus sanguineus (brown dog tick)
