avermectins

The avermectins are a mixture of natural products produced by a soil actinomycete, Streptomyces avermitilis.

The selective toxicity of avermectins to specific invertebrates is believed to be due at least partially to the differential distribution of gamma-aminobutyric acid (GABAergic) neurons which, in mammals, are restricted to the central nervous system (Lasota and Dybas, 1991).

The avermectins have nematicidal, acaricidal and insecticidal activity.

Avermectin research has largely been confined to investigations using the entire organism of Streptomyces avermitilis for the production of avermectins, or using the related S. bikokenkinki, for the production of milbemycins.

In 1983, the high cost of avermectins and their high level of mammalian toxicity, precluded them from registration as stored grain protectants.

Merck Sharp & Dohme Research Laboratories have indicated that although they are seeking to increase the range of food crops on which the use of avermectin is approved, they have no current plans to develop avermectins as grain protectants.

Here we investigated chromosomal instability of Streptomyces avermitilis, an important producer of avermectins, and characterized four gross chromosomal rearrangement events, including a major deletion in the central region.
