Compounds of general formula (I): ##STR1## in which: R.sub.1 represents a hydrogen atom or a lower alkyl group, A represents a hydrogen atom, and in this case B represents a group CO-G, G being: either a heteroaryl group selected from furan, indole, pyrrole, pyridine, quinoline, isoquinoline and benzofuran, optionally substituted with one or more lower alkyl or lower alkoxy groups or a halogen atoms, or a linear or branched lower alkyl group substituted with a carboxyl group, or a linear or branched lower alkenyl group substituted with a carboxyl group, or a phenyl or naphthyl group substituted with a carboxyl group, or alternatively A forms with B a group CO(CH.sub.2).sub.n CH(CH.sub.3) with n being a integer equal to 1, 2, 3 or 4, the CO group being attached to the aromatic ring of the benzoxazolinone at the 5- or 6-position, as well as, where appropriate, their isomers and, when the compound of formula (I) possesses a carboxylic acid group, their addition salts with a pharmaceutically acceptable base, and, when the compound of formula (I) contains a basic group, their addition salts with a pharmaceutically acceptable acid, it being understood that lower alkyl and lower alkenyl mean linear or branched groups comprising from 1 to 6 carbon atoms. Medicinal products.
通式(I)的化合物:##STR1## 其中:R.sub.1代表氢原子或较低的烷基,A代表氢原子,在这种情况下B代表一个CO-G基团,G可以是:从呋喃,吲哚,吡咯,吡啶,喹啉,异喹啉和苯并呋喃中选择的杂环烷基,可选地被一个或多个较低的烷基或较低的烷氧基或卤素原子取代,或被一个羧基取代的线性或支链较低烷基基团,或被一个羧基取代的线性或支链较低烯基基团,或被一个羧基取代的苯基或萘基团,或者A与B形成一个CO(CH.sub.2).sub.n CH(CH.sub.3)基团,其中n是等于1、2、3或4的整数,CO基团连接到苯并噁唑酮芳香环的5-或6-位,以及它们的异构体和,当通式(I)的化合物具有羧酸基团时,它们与药用可接受碱的加合物,以及当通式(I)的化合物含有一种碱性基团时,它们与药用可接受酸的加合物,其中较低的烷基和较低的烯基意味着由1到6个碳原子组成的线性或支链基团。药品。
