Milbemycin A3 oxime is a semi-synthetic macrocyclic lactone prepared by the oxidation and oximation of milbemycin A3. Milbemycin A3 oxime is the minor component (~30%) in the commercial product milbemycin oxime, marketed for endo- and exo-parasite infections.
Milbemycin A3 oxime is soluble in ethanol, methanol, DMF or DMSO. Poor water solubility.

| Mechanism of Action | Like the other milbemycin/avermectins, milbemycin A3 oxime acts by opening glutamate sensitive chloride channels in neurons of invertebrates leading to paralysis by hyperpolarisation of these cells and signal transfer blocking. |
