Four stereoisomers of the title compounds based on side chain ring junctions, (+)-7a, (+)-7b, (-)-7c and (-)-24, were synthesized from (-)-myrtenol and (+)-nopinone. The (1R,2R,3S,5S)-isomer (+)-7b had the most potent inhibitory activity against platelet aggregation and did not show partial agonist activity (shape change of platelets). We also synthesized the antipode, (-)-7b, and derivatives of (+)-7b
由(-)-美登醇和(+)-合成基于侧链环连接的标题化合物的四种立体异构体,(+)-7a,(+)-7b,(-)-7c和(-)-24。 Nopinone。(1R,2R,3S,5S)-异构体(+)-7b对血小板聚集具有最强的抑制活性,并且没有显示出部分激动剂活性(血小板的形状变化)。我们还合成了对映体(-)-7b和(+)-7b的衍生物,在磺酰氨基处34a-n和p具有各种取代基。还制备了一碳同系的化合物(+)-58。测量了这些化合物对血小板聚集的抑制活性。
