Several sulfonyl derivatives (13a-t) of (+/-)-(5Z)-7-(3-endo-aminobicyclo[2.2.1]hept-2-exo-yl)heptenoic acid (VI) were synthesized via its methyl ester 10. Sulfonylation of 10 with 11a-t followed by saponification yielded 13a-t. Inhibitory concentrations (IC50) of the corresponding sodium salts 14a-t for platelet aggregation were measured with rat washed platelets (WP) and rabbit platelet-rich plasma
通过其甲基合成了(+/-)-(5Z)-7-(3-endo-aminobicyclo [2.2.1] hept-2-exo-yl)庚烯酸(VI)的几种磺酰基衍生物(13a-t)酯10。用11a-t磺化10,然后皂化,得到13a-t。用大鼠洗涤的血小板(WP)和兔富含血小板的血浆(PRP)测量相应的钠盐14a-t对血小板聚集的抑制浓度(IC50)。还测量了某些衍生物对大鼠主动脉收缩的IC50值。对于带有芳基磺酰基残基的衍生物,大鼠WP的IC50值从2.9 nM依次增加到14n,14c,14d和14b,具体取决于中间亚甲基的数量。甲基衍生物14e表现出比正己基衍生物14f更高的IC 50值。用对甲基,对氟-,或14a中的对氯基保留或略微降低其IC50值,而pn-戊基或对氧羰基则显着提高其IC50值。代表性的14a抑制(15S)-15-羟基-11,9-(环氧甲氧基)prosta-5(Z),13(E
