Four stereoisomers of 7-oxabicyclo[2.2.1]heptane derivatives with the benzenesulfonylamino group, 11, 14, 23 and 33, were synthesized and their sodium salts were examined in vitro for inhibitory activity against aggregation of rabbit platelet-rich plasma and of rat washed platelets. The trans-isomer 23 exhibited high potency but showed a partial agonistic effect. Compound 11 did not show a partial
合成了具有苯磺酰基氨基基团的7-氧杂双环[2.2.1]庚烷衍生物的四种立体异构体,分别在体外检查了其钠盐对兔富含血小板血浆和大鼠聚集的抑制活性洗净的血小板。反式异构体23显示出高效力,但显示出部分激动作用。尽管化合物11是活性较低的抑制剂,但它没有显示出部分激动作用。合成了以下反式化合物,并测量了其IC50值:具有一个亚甲基链的同系反式异构体(47和53),烯烃衍生物(58)和光学活性衍生物[-]-11和(+)-23) 。
