The present invention relates to 2'-(ortho-chlorobenzoyl)-4'-chloroglycylanilides, compositions thereof, and their use as medicaments, e.g., as anxiolytic agents. The compounds of the invention have the general formula I ##STR1## in which R represents hydrogen or alkyl, R.sub.1 and R.sub.2 may be identical or different and are selected from hydrogen, alkyl, hydroxyalkyl, alkenyl, and alkynyl, possibly substituted by alkyl, and cycloalkyl having three to six members, possibly substituted by alkyl, with the proviso that, when one of R.sub.1 and R.sub.2 represents hydrogen, the other is not lower alkyl or hydroxyalkyl; and with the further proviso that R.sub.1 and R.sub.2 may not simultaneously represent either hydrogen or lower-alkyl. R.sub.1 and R.sub.2 may furthermore form, with the nitrogen atom to which they are connected, a nitrogen heterocycle possibly containing a second heteroatom selected from oxygen and nitrogen.
本发明涉及2'-(邻氯苯甲酰)-4'-氯甘氨基苯酰胺及其组成物,以及它们作为药物的用途,例如作为抗焦虑剂。本发明的化合物具有一般式I
其中R代表氢或烷基,R1和R2可以相同或不同,并且选择自氢,烷基,羟基烷基,烯基和炔基,可能被烷基取代的环烷基,具有三到六个成员,可能被烷基取代,条件是,当R1和R2中的一个代表氢时,另一个不是较低的烷基或羟基烷基;并且进一步规定,R1和R2不能同时代表氢或较低的烷基。R1和R2还可以与它们连接的氮原子形成一种氮杂环,可能含有从氧和氮中选择的第二个杂原子。
