have been prepared. Synthesis of the 15-aza derivative is based on a novel transformation of a ketone to an N-substituted ethylenamine using a formylmethylimino phosphate derivative. Several of the azaprostanoic acid derivatives were found to be potent inhibitors of platelet aggregation induced by arachidonic acid, whereas no effect was observed on ADP-induced primary aggregation, indicating blockade
已经制备了一系列的13-氮杂前列腺素酸(4a-h)和15-氮杂前列腺素酸(11a)。15-氮杂衍生物的合成基于使用甲酰基甲基亚氨基磷酸酯衍生物将酮新颖地转化为N-取代的亚乙基胺。发现几种氮杂前列腺素酸衍生物是花生四烯酸诱导的血小板凝集的有效抑制剂,而未观察到对ADP诱导的初级凝集的影响,表明阻断了花生四烯酸级联反应。该化合物不抑制牛环氧合酶的活性,并假定其作用超出了前列腺素内过氧化物的合成。13-氮杂系列的抑制作用对立体化学和氨基侧链的长度都高度敏感。
