series of novel azulene-1 carboxylic acid derivatives 28-30, azulene-1 sulfonic acid sodium salts 41a-c, and related compounds were synthesized. These compounds were tested for TXA2 receptor antagonistic activity. The inhibitory concentrations (IC50) of these compounds for vascular contraction (TXA2 tau receptor) and platelet aggregation (TXA2 alpha receptor) induced by (15S)-15-hydroxy-11 alpha,9
合成了一系列新颖的a1羧酸衍生物28-30,-11磺酸钠盐41a-c和相关化合物。测试这些化合物的TXA2受体拮抗活性。这些化合物对(15S)-15-羟基-11 alpha,9 alpha-(epoxymethano)prosta-5(Z)诱导的血管收缩(TXA2 tau受体)和血小板聚集(TXA2 alpha受体)的抑制浓度(IC50)获得了13,(E)-二烯酸(U-46619)。Azulene-1-磺酸钠盐41a-c的效力是Azulene-1-羧酸28-30的3倍以上。最有效的化合物41b在抑制血管收缩(tau受体)方面比TXA2拮抗剂BM13,177强4个数量级,IC50为9.0 x 10(-10)M. 还发现化合物41b是tau受体选择性拮抗剂(收缩的IC50 /聚集的IC50 = 378),在浓度高达10(-4)M时没有TXA2合成酶抑制活性,在浓度高达10(-4)M时没有部分激
