Novel 3-quinoline-carboxamides of the formula ##STR1## wherein R is in 6 or 7-position and is selected from the group consisting of hydrogen, halogen, alkyl of 1 to 6 carbon atoms, cycloalkyl of 3 to 6 carbon atoms, alkoxy of 1 to 6 carbon atoms, --CF.sub.3, --SCF.sub.3 and CH.sub.3 S--, R.sub.1 is selected from the group consisting of hydrogen, alkyl of 1 to 6 carbon atoms, phenyl and benzyl, R.sub.2 is --NHR.sub.4, R.sub.4 is selected from the group consisting of alkyl of 2 to 6 carbon atoms, substituted aryl of 6 to 10 carbon atoms and substituted heterocycle of an aromatic character of 3 to 5 carbon atoms with the proviso that when R.sub.4 is a mono substituted aryl or heterocycle, the substituent is different from R of the quinoline when it is a halogen and R.sub.3 is selected from the group consisting of hydrogen and --OH and their non-toxic, pharmaceutically acceptable acid addition salts having remarkable anxiolytic properties capable of lessening emotional reactions and diminishing states of psychic tension and their preparation.
3-喹啉羧酰胺的结构式为##STR1##,其中R位于6或7位置,选自氢、卤素、1至6个碳原子的烷基、3至6个碳原子的环烷基、1至6个碳原子的烷氧基、--CF.sub.3、--SCF.sub.3和CH.sub.3S--中的一种;R.sub.1选自氢、1至6个碳原子的烷基、苯基和苄基;R.sub.2为--NHR.sub.4,R.sub.4选自2至6个碳原子的烷基、6至10个碳原子的取代芳基和3至5个碳原子的具有芳香性质的取代杂环,但当R.sub.4为单取代芳基或杂环时,取代基与喹啉的R不同,且当R为卤素时,R.sub.3选自氢和--OH,其非毒性、药用可接受的酸盐具有显著的抗焦虑特性,能减轻情绪反应并减少心理紧张状态,以及其制备方法。
