Moxidectin

Moxidectin is a macrocyclic lactone endectocide and a derivative of nemadectin. It reduces fecal nematode egg counts by 98.4 and 99.8% in naturally infected calves when administered subcutaneously at doses of 0.2 and 0.3 mg/kg, respectively. Moxidectin (0.2 and 0.3 mg/kg) reduces the worm burden of O. ostertagi and T. axei in the abomasum, and Cooperia species and N. helvetianus in the small intestine, of naturally infected calves. It potentiates GABA-gated currents in Xenopus oocytes expressing rat alpha1beta2gamma2 subunit-containing GABAA receptors with an EC50 value of 11.8 nM. Formulations containing moxidectin have been used in the treatment of onchocerciasis, as well as in the prevention and treatment of parasitic infections in veterinary medicine.Formal Name: (6R,23E,25S)-5-O-demethyl-28-deoxy-25-[(1E)-1,3-dimethyl-1-buten-1-yl]-6,28-epoxy-23-(methoxyimino)-milbemycin B.
