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.
揭示了以下化合物的结构公式:##STR1## 其中:R.sup.1是较低的烷基基团;R.sup.2和R.sup.3分别是氢或较低的烷基或R.sup.2和R.sup.3结合可形成-(CH.sub.2(.sub.4)-或-CH.dbd.CH-CH.dbd.CH-;α是一个含有1至3个异原子(选自氮、氧和硫的群)的5-或6成员杂环芳基环,或者是吡唑啉-N-氧化物环、吡嗪啉-N-氧化物环或嘧啶-N-氧化物环基团,其中这些异杂环芳基环可选择地具有1至3个选自较低烷基、卤素、苯基、较低烷氧羰基、氨基、较低烷氧基和羟基较低烷基的取代基,但前提是所述的5-或6-成员杂环芳基环不是噻唑基、异噻唑基、吡啶基或1,3,5-三嗪基团;或其盐。这些化合物及其盐具有抗炎活性和抑制脂氧合酶活性。
