Abstract
Compounds of the formula ##STR1## wherein A taken together with the two carbon atoms denoted as .alpha. and .beta. is a group of the formula ##STR2## and the dotted line is the double bond present in formulas (i) and (iii); and wherein n is zero, 1, 2 or 3, one of R.sup.1 and R.sup.2 is carboxy or alkoxycarbonyl and the other is hydrogen, R.sup.3 is hydrogen, alkyl, alkoxy, aryloxy, azido, cyano or alkylthio, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 each, independently, is hydrogen or alkyl or, when R.sup.1 is carboxy or alkoxycarbonyl and n stands for 1, R.sup.4 and R.sup.6 taken together can be a carbon-carbon bond or, when R.sup.2 is carboxy or alkoxycarbonyl, R.sup.5 and R.sup.7 taken together can be a carbon-carbon bond, R.sup.8 is halogen, alkyl, haloalkyl or alkoxy and R.sup.9 is hydrogen, halogen, alkyl or alkoxy, and pharmaceutically acceptable salts of the compounds of formula I in which one of R.sup.1 and R.sup.2 is carboxy and the other is hydrogen with bases, can be used as medicaments for the treatment of rheumatoid arthritis, inflammatory respiratory diseases, inflammatory bowel disease, shock and inflammation associated with ischemia. The compounds of formula I can be …
