The invention concerns sulphonamide derivatives of the formula I wherein R1 includes (1-4C)alkyl; R2 and R3 together form ?A2 ?X2 ?A3? which defines a ring having 5 to 7 ring atoms, wherein A2 and A3 each is (1-3 C)alkylene and X2 is oxy, thio, sulphinyl or sulphonyl; A1 is a direct link to X1 or is (1-3 C)alkylene; X1 is oxy, thio, sulphinyl, sulphonyl or imino; Ar is optionally substituted phenylene or Ar is pyridylene; Q is nitrogen or of the formula CR7, wherein R7 includes hydrogen, halogeno, (1-4 C)alkyl and (1-4 C)alkoxy; each of R4 and R5 is (1-4 C)alkyl, (3-4 C)alkenyl, (3-4 C)alkynyl or optionally substituted phenyl, benzyl or pyridyl, or R5 may be hydrogen; and R6 has any of the meanings defined for R7; or a pharmaceutically-acceptable salt thereof; processes for their manufacture; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors
