<p>"NAPHTHYRIDINE DERIVATIVES" 2,3,3a,4,5,6-Hexahydro-1H-indolo¢3,2,1-de!- ¢1,5-naphthyridine! derivatives of the general formula: in which R1 is in the 9- or 10-position and represents a hydrogen atom, a halogen atom or a C1-4 alkyl or C1-4 alkoxy radical and R2 represents a hydrogen atom or a C1-4 alkyl radical, are new compounds useful in therapy as they possess an anti-anoxia action and a psychotropic action. They can be prepared by reduction of the carbonyl group of corresponding 1,2,3,3a,4,5-hexahydro-6H-indolo¢3,2,1-de!¢1,5-naphthyridine!-6-one derivatives, which are known compounds, to methylene.</p> |
