Open the CIPO recordAbstract From the Canadian patent
A novel protein having been cloned in mammals for the first time which exerts a dicarbonylreductase activity, has an amino acid sequence showing a homology of about 70 % with a known mouse lung-specific carbonylreductase (CR) and shows a high reductive activity on diacetyl employed as the substrate. This protein is localized around kidney medullary nipples and is expressed specifically in the kidneys. The expression of this protein is significantly reduced in the kidneys of diabetic model mice.

Why it's free to use
- Filed March 11, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 11, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 11, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
