Open the CIPO recordAbstract From the Canadian patent
Pre-treatment with .alpha. .beta. unsaturated aryl sulfones protects normal cells from the toxic side effects of ionizing radiation. Administration of a radioprotective .alpha. .beta. unsaturated aryl sulfone compound to a patient prior to anticancer radiotherapy reduces the cytotoxic side effects of the radiation on normal cells. The radioprotective effect of the .alpha. .beta. unsaturated aryl sulfone allows the clinician to safely increase the dosage of anticancer radiation. In some instances amelioration of toxicity following , inadvertent radiation exposure may be mitigated with administration of .alpha. .beta. unsatured arylsulfone.

Why it's free to use
- Filed February 28, 2002 and granted August 9, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 28, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 28, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
