<p>Triazine derivatives of formula (I) <CHEM> or a salt thereof, wherein R<1> represents a halogen atom or a group selected from hydroxy; C1-8 alkyl C1-6 alkoxy; C1-3 alkoxy C1-3 alkoxy; phenoxy or phenyl C1-3 alkoxy, wherein the phenyl group is optionally substituted by a halogen atom or a group selected from C1-3 alkyl, C1-3 alkoxy, or hydroxy; fluoro C1-3 alkyl; cyano; -CO2R<3>, wherein R<3> represents a hydrogen atom or a C1-4 alkyl group; -CONR<4>R<5>, wherein R<4> and R<5> each independently represents a hydrogen atom or a C1-4 alkyl group, or, together with the nitrogen atom to which they are attached, form a saturated 5- to 7- membered ring, which ring optionally contains one or more atoms selected from an oxygen or a sulphur atom, or a group selected from -NH- or -N(CH3)-; and R<2> represents a hydrogen or halogen atom, or a group selected from hydroxy, C1-6 alkyl or C1-6 alkoxy; are inhibitors of the enzyme 5-lipoxygenase. Processes for preparing the triazine derivatives of formula (I) and compositions containing them are also described.</p> |
