Abstract
Novel compounds of the formula: ##STR1## wherein A is CHOH, CHO or COOR; R is hydrogen or a lower alkyl group of 1 to 4 carbon atoms; and the pharmaceutically acceptable, non-toxic salts of compounds in which R is hydrogen; and X is hydrogen, o-, m- or p-halo(fluoro, chloro or bromo), o-, m- or p-methyl or o-, m- or p-methoxy. These compounds possess prostaglandin-like activity and thus are useful in the treatment of mammals where prostaglandins are indicated. They are particularly useful as inhibitors of gastric acid secretions and as agents for the control of asthmatic attack, because of their bronchodilating activity.
