Abstract
Abstract A compound of the formula ##STR1## wherein n is an integer from 2 to 4; m is an integer from 3 to 5; R is OM, OR 1 or NR 2 R 3 where M is a pharmaceutically acceptable cation; R 1 , R 2 and R 3 are the same or different and selected from the group consisting of hydrogen, C 1 -C 12 branched, unbranched or cyclic alkyl, aryl and aralkyl; or R 2 and R 3 taken together form a group of the formula ##STR2## can be used as an inhibitor of the lipoxygenase pathway of the arachidonic acid cascade in animals.
