The present invention is directed to an acid amide of the formula ##STR1## wherein R.sup.1 represents hydrogen or nitro, R.sup.2 and R.sup.3 stand for, independently from each other, hydrogen, lower alkyl or lower alkenyl each optionally carrying a substituent selected from the group consisting of halogen, hydroxy, lower alkoxy, di(lower alkyl)amino, phenyl-lower alkoxycarbonyl and a 5- to 6-membered saturated hetero-ring selected from the group consisting of piperidino, pyrrolidino, piperazino and morpholino; or R.sup.2 and R.sup.3 form, together with the adjacent nitrogen atom, a 6-membered saturated heterocyclic group selected from the group consisting of piperidino, pyrrolidino, piperazino and morpholino, said heterocyclic group optionally carrying a hydroxy or a hydroxy-lower alkyl group; or a pharmaceutically acceptable salt thereof; process of making and pharmaceutical compositions and methods of treating.
本发明涉及一种酸酰胺,其化学式为##STR1##其中R.sup.1代表氢或硝基,R.sup.2和R.sup.3分别代表氢,较低的烷基或较低的烯基,每个都可以携带来自卤素、羟基、较低的烷氧基、二(较低的烷基)氨基、苯基-较低的烷氧羰基和来自哌啶基、吡咯啉基、哌嗪基和吗啉基的5-至6-成员饱和杂环中选择的取代基;或者R.sup.2和R.sup.3与相邻的氮原子一起形成来自哌啶基、吡咯啉基、哌嗪基和吗啉基的6-成员饱和杂环,该杂环可以携带羟基或羟基-较低的烷基基团;或其药学上可接受的盐;制备方法和治疗的制药组合物和方法。
