    摘要: Disclosed are compounds of the formula ##STR1## wherein: R.sup.1 is a lower alkyl group;R.sup.2 and R.sup.3 are each hydrogen or lower alkyl or R.sup.2 and R.sup.3 taken together may form --(CH.sub.2 (.sub.4)-- or --CH.dbd.CH--CH.dbd.CH--;.alpha. 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.
