The present invention discloses sulfonamide derivative represented by the following general formula: ##STR1## [wherein, R.sub.1 is (i) --COOR.sub.2 (where, R.sub.2 is (1) hydrogen, (2) a pharmacologically acceptable cation, or (3) an alkyl having 1 to 14 carbon atoms) or, (ii) --C(.dbd.O)--R.sub.3 (wherein, R.sub.3 represents an alkyl having 1 to 4 carbon atoms); A is (i) --(CH.sub.2)n-- (wherein, n represents an integer of 0 to 3), (ii) --CH.dbd.CH--, or the group: (iii) --O--C(R.sub.4) (R.sub.5)-- (wherein, R.sub.4 and R.sub.5 represent (1) hydrogen or (2) an alkyl having 1 to 4 carbon atoms, and R.sub.4 and R.sub.5 may be identical or different); and, w is NH or --O--], as well as a thromboxane A2 receptor antagonistic drug having said derivative for its active ingredient. Since the compound of the present invention has excellent thromboxane A2 receptor antagonistic action, it can be used as a thromboxane A2 receptor antagonist of high activity and long duration.
本发明公开了以下通式所表示的磺酰胺衍生物:##STR1## [其中,R.sub.1是(i)--COOR.sub.2(其中,R.sub.2是(1)氢,(2)药理学上可接受的阳离子,或(3)具有1到14个碳原子的烷基)或(ii)--C(.dbd.O)--R.sub.3(其中,R.sub.3代表具有1到4个碳原子的烷基);A是(i)--(CH.sub.2)n--(其中,n代表0到3的整数),(ii)--CH.dbd.CH--,或者该基团:(iii)--O--C(R.sub.4)(R.sub.5)--(其中,R.sub.4和R.sub.5代表(1)氢或(2)具有1到4个碳原子的烷基,且R.sub.4和R.sub.5可以相同也可以不同);w是NH或--O--],以及以该衍生物为活性成分的血栓素A2受体拮抗药物。由于本发明化合物具有出色的血栓素A2受体拮抗作用,因此可以用作高活性和长持续时间的血栓素A2受体拮抗剂。
