The invention concerns benzenesulphonamide derivatives of the formula I
wherein R¹ is (1-4C)alkyl, (3-4C)alkenyl or (3-4C)alkynyl;
R² and R³ together form -A²-X²-A³- which defines a ring having 5 or 6 ring atoms, wherein A² and A³ each is (1-3C)alkylene and X² is oxy, thio, sulphinyl or sulphonyl;
A¹ is a direct link to X¹ or is (1-3C)alkylene;
X¹ is oxy, thio or imino;
Ar is optionally substituted phenylene;
R⁴ is (1-4C)alkyl, fluoro-(2-4C)alkyl or optionally substituted phenyl or a heterocyclic moiety;
R⁵ is hydrogen or (1-4C)alkyl; and
R⁶ is hydrogen, halogeno, trifluoromethyl, (1-4C)alkyl or (1-4C)alkoxy;
or a pharmaceutically-acceptable salt thereof;
processes for their manufacture; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors.
