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
制备了 30 种标题化合物,并在 Born 试验中测试了它们的抗血小板活性。5 种亚硝胺在低于 10 μmol/L 的浓度下最大抑制胶原蛋白聚集。在体内血栓形成模型中研究了四种化合物。口服给药 (60 mg/kg) 后 2 小时,在大鼠的肠系膜小动脉中观察到血栓形成的抑制率为 29% 至 53%。对静脉的影响不太明显(10-22%)。对于一种化合物,口服应用 4 小时后仍可证明这些作用。
