Novel peptide derivatives having RGD as a basic structure were found which have a platelet aggregation-inhibiting action blood, coagulation-inhibiting action and cell adhesion-inhibiting action. Utlizing these effects of the peptide derivatives the following, agents which comprise the peptides as active ingredients were provided: platelet aggregation-inhibiting agents that are effective in thrombolus during and after the treatment of thrombolysis and thromboembolism and that can further prevent reobstruction and cardiac infarction; blood coagulation-inhibiting agents that can inhibit blood coagulation which is the main cause of thrombus formation during extracorporeal circulation; cell …

Why it's free to use
- Filed September 7, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 7, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 7, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
