collagen with IC50 values between 3 and 10 μmol/L in the Born test. ADP, PAF, and adrenaline were used as specific aggregation inducers to examine the mechanism of the anti‐aggregating activity. An astonishing pattern of activities in the nanomolar, with 6m, 7b, 8 and even subnanomolar range, with 6b, was observed. Compound 6b inhibited the platelet aggregation induced by ADP with an IC50 = 0.45 nM (6m: 3
四种嘌呤 - 2,6 - 二胺,4a, b, 5a, b,十九种 N-(嘌呤 - 2 - 基)苯甲酰胺 6a - q, 7b 和一种 N-(嘌呤 - 2 - 基) -2 - 呋喃甲酰胺 8首次制备并测试它们对血小板聚集的抑制作用。6a、b、h、m、o、p六种化合物在Born试验中抑制胶原诱导的血小板聚集,IC50值在3~10μmol/L之间。ADP、PAF和肾上腺素被用作特异性聚集诱导剂来检查抗聚集活性的机制。观察到惊人的纳米摩尔级活动模式,6m、7b、8 甚至亚纳摩尔范围(6b)。化合物6b以IC50 = 0.45 nM(6m:3.5 nM;8:30 nM)抑制ADP诱导的血小板聚集。化合物 7b 显示出对诱导剂肾上腺素的拮抗作用,IC 50 = 1.8 nM (6o: 20 nM; 8: 30 nM)。
