The invention concerns a cycloalkane derivative of the formula I, ##STR1## wherein Ar.sup.1 is optionally substituted phenyl or naphthyl; A.sup.1 is (1-6C)alkylene, (3-6C)alkenylene, (3-6C)alkynylene or cyclo(3-6C)alkylene; Ar.sup.2 is optionally substituted phenylene, or a 6 membered heterocyclene moiety containing up to three nitrogen atoms; R.sup.1 is hydrogen, (1-6C)alkyl, (3-6C)alkenyl, (3-6C)alkynyl, cyano-(1-4C)alkyl or (2-4C)alkanoyl, or optionally substituted banzoyl; and R.sup.2 and R.sup.3 together form a (3-6C)alkylene group which defines an optionally substituted ring having 4 to 7 ring atoms; or a pharmaceutically-acceptable salt thereof. The compounds of the invention are inhibitors of the enzyme 5-lipoxygenase.
