Tricyclic derivatives of substituted pyrrole acids, e.g., substituted 4,10-dihydro-10-oxo-1H-[1]benzoxepino[4,3-b]pyrrole-2-acetic acids or the 5-thia analogs thereof have been prepared via hydrolysis of a precursor or decarboxylation of a precursor-diacid. These tricyclic compounds are found to have high analgesic and anti-inflammatory activities but low ulcerogenic side effects.
取代吡咯酸的三环衍生物,例如取代的4,10-二氢-10-氧基-1H-[1]苯并噁哌诺[4,3-b]吡咯-2-乙酸或其5-硫代类似物,是通过水解前体或前体二酸的脱羧制备的。这些三环化合物被发现具有高镇痛和抗炎活性,但溃疡原发性副作用较低。
