, (2008/06/13)
The invention concerns a thiazole of the formula I, STR1 wherein Q1 is an optionally substituted 6-membered monocyclic or 10-membered bicyclic heterocyclic moiety containing one or two nitrogen atoms; X is oxy, thio, sulphinyl, sulphonyl or imino; Ar is phenylene which may optionally bear one or two substituents, or Ar is an optionally substituted 6-membered heterocyclene moiety continuing up to three nitrogen atoms; R1 is hydrogen, (1-6C)alkyl, (2-6C)alkenyl, (2-6C)alkynyl or substituted (1-4C)alkyl; R2 is hydrogen, (1-6C)alkyl, (3-6C)alkenyl, (3-6C)alkynyl or substituted (1-4C)alkyl or R2 is optionally substituted benzoyl; and Q2 is optionally substituted thiazolyl; or a pharmaceutically-acceptable salt thereof. The invention also concerns processes for the manufacture of a thiazole of the formula I and pharmaceutical compositions containing said thiazole.

The invention concerns a heterocycle of the formula I wherein Q is an optionally substituted 6-membered monocyclic or 10-membered bicyclic heterocyclic moiety containing one or two nitrogen atoms; A is (1-6C)alkylene, (3-6C)alkenylene, (3-6C)alkynylene or cyclo(3-6C)alkylene; X is oxy, thio, sulphinyl, sulphonyl or imino; Ar is phenylene which may optionally bear one or two substituents or Ar is an optionally substituted 6-membered heterocyclene moiety containing up to three nitrogen atoms; R 1 is hydrogen, (1-6C)alkyl, (3-6C)alkenyl, (3-6C)alkynyl, cyano-(1-4C)alkyl or (2-4C)alkanoyl, or optionally substituted benzoyl; and R 2 and R 3 together form a group of the formula --A 2 --X 2 --A 3 -- which, together with the carbon atom to which A 2 and A 3 are attached, defines a ring having 4 to 7 ring atoms, wherein A 2 and A 3, which may be the same or different, each is (1-4C)alkylene and X 2 is oxy, thio, sulphinyl, sulphonyl or imino; or a pharmaceutically-acceptable salt thereof. The compounds of the invention are inhibitors of the enzyme 5-lipoxygenase.
