Abstract From the Canadian patent

Promising groups of environmetally-safe insecticides consist of analogues of insect hormones, such as juvenile hormone and antagonists of such hormones. , The traditional bioassay approach for screening potential juvenile hormone analogs and antagonists is slow, expensive and inefficient. A recombinant bHLH- PAS-juvenile hormone receptor, isolated from the methoprene-tolerant locus on Drosophila, provides the basis of in vitro and in vivo binding assays that can be used to discover new juvenile hormone-type targeted insecticides. Moreover the nucleotide sequence of the Drosophila bHLH-PAS/JHR polypeptide provides tools for isolating juvenile hormone receptor genes from other insect …

Why it's free to use

  • Filed April 14, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 14, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 14, 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.
