A novel series of N-substituted 3-(1H-imidazol-1-ylmethyl)indole carboxylic acid derivatives were prepared and evaluated for thromboxane A2 (TXA2) synthetase-inhibitory and histaminergic H1-blocking activity. Among the compounds synthesized, indole-6-carboxylic acid derivatives showed higher activities than the other positioal isomers of carboxylic acid. 1-[3-(4-Benzhyrdyl-1-piperazinyl)propyl]-3-(1H-imidazol-1-ylmethyl)-1H-indole-6-carboxylic acid (12) had the strongest thromboxane synthetase inhibitory activity (IC50=5×10-8M) and H1-blocking activity (IC50=8×10-9M).
制备了一系列N-取代的3-(1H-咪唑-1-基甲基)吲哚羧酸衍生物,并评估了它们对血栓素A2(TXA2)合成酶抑制和组胺H1受体阻断的活性。在合成的化合物中,6-吲哚羧酸衍生物显示出比其他位置异构体更高的活性。1-[3-(4-苯并氢吡啶-1-基)丙基]-3-(1H-咪唑-1-基甲基)-1H-吲哚-6-羧酸(12)具有最强的血栓素合成酶抑制活性(IC50=5×10-8M)和H1受体阻断活性(IC50=8×10-9M)。
