Compounds antagonistic of the pain enhancing effects of prostaglandins are disclosed. The compounds comprise an optionally-substituted A ring with a --CH(R.sup.3)N(R.sup.2)B--R.sup.1 and --OD groups positioned in a 1,2 relationship to one another on ring carbon atoms. The 3-position ring-atom is not substituted. B is also an optionally-substituted ring and the group R.sup.1 is positioned on B in a 1,3 or 1,4 relationship with the --CH(R.sup.3)N(R.sup.2)-- linking group. R.sup.1, R.sup.2 and R.sup.3 and D can be a number of different organic or halogen moieties. N-oxides of --NR.sup.2 and S-oxides of sulphur containing rings are disclosed as are processes for the preparation of the compounds, intermediates in their preparation, pharmaceutical compositions containing them, and their use as therapeutic agents.
抗拮抗前列腺素增强疼痛作用的化合物被披露。这些化合物包括一个可选择取代的A环,其中在环碳原子上,一个--CH(R.sup.3)N(R.sup.2)B--R.sup.1和--OD基团以1,2的关系相互定位。3位环原子未被取代。B也是一个可选择取代的环,基团R.sup.1在B上以1,3或1,4的关系与--CH(R.sup.3)N(R.sup.2)--连接基团定位。R.sup.1、R.sup.2和R.sup.3以及D可以是多种不同的有机或卤素基团。还披露了--NR.sup.2的N-氧化物和含硫环的S-氧化物,以及制备这些化合物、其制备中间体、含有它们的药物组合物以及它们作为治疗剂的用途的方法。
