Article abstract of DOI:10.1002/ardp.19943271204

Thirty title compounds were prepared and tested for their antiplatelet activity in the Born-test. Five nitrosimines inhibit the aggregation induced by collagen in concentrations below 10 μmol/L halfmaximally. Four compounds were investigated in an in vivo thrombosis model. An inhibition of thrombosis between 29 and 53% was observed in mesenteric arterioles of rats 2 h after p.o. administration (60 mg/kg). The effect in venoles was less pronounced (10-22%). For one compound these effects could still be demonstrated 4 h after oral application.
