摘要：

A series of 4-[2-(arylsulfonylamino)ethylthio]phenoxyacetic acids and related compounds were synthesized. The compounds were tested for their thromboxane A2 (TXA2) receptor antagonizing effects on (15S)-15-hydroxy-11a,9a-(epoxymethano)prosta-5(Z),13(E)-dienoic acid (U-46619)-induced aggregation of rabbit platelet-rich plasma (PRP). Among the compounds synthesized, 3-{4-[2-(arylsulfonylamino)ethylthio]phenyl}propionic acids 26a-e,g showed potent TXA2 receptor antagonist activity. The most potent compound, 3-14-[2-(4-chlorophenylsulfonylamino)ethylthio]phenyl}propionic acid 26c was more than 10-fold more potent in TXA2 receptor antagonizing activity (IC50 = 1.1 X 10(-6) M) than sulotroban (BM- 1 3177) on rabbit platelets. Compound 26c was also more than 10-fold more potent in TXA2-inhibitory activity than sulotroban on rat aorta smooth muscle (pA2 7.7).
