Abstract From the Canadian patent

To date, L-glutamate-gated chloride (GluC1) channels have been observed only in invertebrate organisms. Modulators of this channel (either agonists or antagonists) will interfere with neurotransmission. For example agents such , as avermectins activate the GluCl causing paralysis due to blocking of , neurotransmitter release resulting in death of the organism. Because GluCl channels are invertebrate specific, they are excellent targets for the discovery of novel insecticides, anthelminths and parasiticides that will display a marked safety profile because of the lack of mechanism based toxicity in vertebrate organisms. The present specification discloses isolation of a cDNA clone …

Why it's free to use

  • Filed August 10, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 10, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 10, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
