Open the CIPO recordAbstract From the Canadian patent
Peptidic inhibitors of hepatitis C virus NS3 protease are disclosed which are based on the P and P' regions of the natural substrate. The P' part of the inhibitor is optimised to achieve maximum binding energy through interaction with the S' region of the enzyme. By selecting amino acids such that the inhibitor is substantially not cleavable by the NS3 protease inhibitors having potency in the low nanomolar to sub-nanomolar range can be achieved.

Why it's free to use
- Filed November 24, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 24, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 24, 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.
