Doramectin was developed as an anthelmintic for internal parasite control. The presence of the cyclohexyl group replacing the sec-butyl moiety affords greater hydrophobicity and longer biological half-life compared to avermectin. Like the other milbemycin/avermectins, it selectively binds to parasite glutamate-gated chloride ion channels and disrupts neurotransmission leading to paralysis and death of the parasite.Antibacterial. A mutational biosynthetic antiparasitic antibiotic. Mutational biosynthetic antiparasitic antibiotic structurally related to the avermectins
