    Milbemycin A3

    €339,85 - €1.187,61

    Milbemycin A3 belongs to the family of Milbemycins, 16-membered macrocyclic lactone antibiotics with a 6,6-membered spiroketal ring system.  Milbemycin A3 is a highly selective and potent nematocide and insecticide.  Milbemycin A3 is a major member of a group of analogs containing a 25-methyl substituent.  Milbemycin A3 is a metabolite derived from fermentation of the soil bacterium Streptomyces hydroscopicus subsp. aureolarcrimosus.  Milbemycins are analogs of the avermectins.  Other Milbemycins include Milbemycin B through H.

    Milbemycin A3 is soluble in ethanol, methanol, DMF and DMSO but has poor water solubility.

    We also offer:

    • Milbemycin A3 Oxime (M058)
    Mechanism of Action Like the closely related avermectins, Milbemycins are thought to act by opening glutamate sensitive and GABA-sensitive chloride channels.
    Spectrum Milbemycin A3 has activity against insects including mites, nematodes, worms, ticks, flights, and agricultural pests.
    Plant Biology Applications Milbemectin is used as an agri-chemical for crop protection in soft fruits, citrus fruit, top fruit, aubergines and others to combat mites and leaf miners.
    Insect Biology Applications

    Milbemectin is a GABA inhibitor and can act as an agonist of the RDL GABA receptor in Drosophila.
