Abstract: Compounds represented by the general formula: ##STR1## in which R.sub.1 and R.sub.2 are selected from hydrogen, C.sub.1 -C.sub.6 alkyl or C.sub.2 -C.sub.6 alkenyl , phenyl or benzyl or R.sub.1 and R.sub.2 form together with the nitrogen atom to which they are attached a C.sub.4 -C.sub.8 saturated heterocycle, R.sub.3 is selected from hydrogen, C.sub.1 -C.sub.6 alkyl, phenyl or C.sub.7 -C.sub.9 phenyl-alkyl, R.sub.4 is selected from hydrogen or C.sub.1 -C.sub.4 alkyl, R.sub.5 and R.sub.6 are selected from hydrogen or halogen, C.sub.1 -C.sub.3 or alkoxy, nitro or trifluoromethyl; Z is selected from OH, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.4 alkyl, benzyl, C.sub.4 -C.sub.6 aryl with or without a heteroatom, or NR.sub.8 R.sub.9, R.sub.8 and R.sub.9 being selected from hydrogen, C.sub.1 -C.sub.4 alkyl, phenyl or benzyl; R.sub.10 is selected from hydrogen, C.sub.1 -C.sub.

Abstract: Compounds represented by the general formula ##STR1## in which R.sub.1 and R.sub.2 are independently selected from hydrogen, C.sub.1 -C.sub.6 alkyl, phenyl or benzyl, or R.sub.1 and R.sub.2 may form together with the nitrogen atom to which they are attached a C.sub.4 -C.sub.8 saturated heterocycle, R.sub.3 and R.sub.4 are independently selected from hydrogen or C hd 1-C.sub.6 alkyl, R.sub.5 is selected from hydrogen or halogen, or C.sub.1 -C.sub.4 alkyl, C.sub.1 -C hd 4 alkoxy, nitro or trifluoromethyl, n is 1, 2 or 3, and one of the symbols A, B, C or D represents N and the others represent CH, as well as the N-oxids and the the pharmaceutically acceptable acid addition salts and their salts with bases. The compounds have nervous system affecting properties.

Abstract: The present invention concerns new derivatives of 4-oxo-1,4-dihydro-quinoline 3-carboxamide, answering to the following general formula: ##STR1## in which: R.sub.1 represents a linear or branched lower alkyl radical, containing from 1 to 5 carbon atoms; an alkenyl or alkynyl radical containing from 2 to 5 carbon atoms; or a cycloalkyl radical containing from 3 to 5 carbon atoms,R.sub.2 represents an alkyl radical containing from 1 to 4 carbon atoms, n is equal to 1 or 2,X represents a hydrogen, a halogen, a lower alkoxy or alkyl group.The invention also concerns their application as medicaments and the compositions containing them.
