Abstract From the Canadian patent

A novel nuclear receptor, termed the steroid and xenobiotic receptor (SXR) a , broad-specificity sensing receptor that is a novel branch of the nuclear receptor superfamily, has been discovered. SXR forms a heterodimer with RXR that can bind to and induce transcription from response elements present in steroid-inducible cytochrome P450 genes in response to hundreds of natural and synthetic compounds with biological activity including therapeutic steroids , as well as dietary steroids and lipids. Instead of hundreds of receptors one , for each inducing compound, the invention SXR receptors monitor aggregate levels of inducers to trigger production of metabolizing enzymes in a …

Why it's free to use

  • Filed December 8, 2000 and granted February 3, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 8, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 8, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
