Open the CIPO recordAbstract From the Canadian patent
The present invention is concerned with modified biological peptides providing increased potency, prolonged activity and/or increased half-life thereof. The modification is made via coupling through an amide bond with at least one conformationally rigid substituent, either at the N-terminal of the peptide the C-terminal of the peptide, on a free amino or carboxyl group along the peptide chain, or at a plurality of these sites. Those peptides exhibit clinical usefulness for example in treating states of insulin resistance associated with pathologies such as type II diabetes.

Why it's free to use
- Filed August 2, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 2, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 2, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
