Disclosed are compounds of the formula
wherein:
R1 is a lower alkyl group;
R2 and R3 are each hydrogen or lower alkyl or R2 and R3 taken together may form -(CH2)4-or -CH = CH-CH = CH-;
a is a 5-or 6-membered heteroaromatic ring group containing 1 to 3 hetero-atoms selected from the group consisting of nitrogen, oxygen and sulfur, or a pyrazine-N-oxide ring, pyridazine-N-oxide ring or pyrimidine-N-oxide ring group, wherein each of these heteroaromatic ring groups may optionally have 1 to 3 substituents selected from the group consisting of a lower alkyl, halogen, phenyl, lower alkoxycarbonyl, amino, lower alkoxy and hydroxy-lower alkyl, with the proviso that said 5-or 6- membered heteroaromatic ring group is not thiazolyl, isothiazolyl, pyridyl or 1,3,5-triazinyl group; or salts thereof. These compounds-and salts thereof have anti-inflammatory activity and lipoxygenase- inhibitory activity.
