Abstract

A newly synthesized 13-aza derivative of prostanoic acid (13-APA) specifically inhibited human platelet aggregation induced by arachidonic acid, prostaglandin H2, or the stable endoperoxide analog (15S)-hydroxy-9 alpha,11 alpha-)epoxymethano)-prosta-5Z,13E-dienoic acid. 13-APA also inhibited [14C]serotonin release in response to arachidonic acid, ADP, or thrombin, but did not inhibit primary aggregation induced by ADP or thrombin. 13-APA completely blocked prostaglandin H2-induced aggregation in indomethacin-treated resuspended platelets but did not inhibit thromboxane synthesis. We therefore conclude that 13-APA acts as a direct antagonist of the platelet thromboxane/endoperoxide receptor.

摘要

一种新合成的前列腺酸13-氮杂衍生物(13-APA)特异性抑制由花生四烯酸、前列腺素H2或稳定的内过氧化物类似物(15S)-羟基-9α,11α-(环氧亚甲基)-前列腺-5Z,13E-二烯酸诱导的人血小板聚集。13-APA还抑制因花生四烯酸、ADP或凝血酶引起的[14C]5-羟色胺释放,但不抑制由ADP或凝血酶诱导的初始聚集。13-APA完全阻断了吲哚美辛处理的重悬血小板中前列腺素H2诱导的聚集,但不抑制血栓素的合成。因此,我们得出结论,13-APA作为血小板血栓素/内过氧化物受体的直接拮抗剂发挥作用。
