摘要:
Pyrimido- and imidazo-pyridoindole derivatives, in the form of racemates or optically active isomers, of formula: ##STR1## in which n=0 or 1, R.sub.1 =H, Hal, alkyl or alkoxy or CF.sub.3, R.sub.2 =H, alkyl, cycloalkyl-alkyl, cycloalkyl, N,N-dialkylaminoalkyl or phenyl, R.sub.3 =H or alkyl and R.sub.4 =H, alkyl or benzyl are useful as anti-anoxia or psychotropic agents in therapy. They are prepared by cyclizing a compound of formula: ##STR2## wherein R.sub.5 is alkyl, by heating it in an acidic medium, such as ethanolic hydrogen chloride.
摘要:
Pyridoindole derivatives of formula ##STR1## n=0 or 1; R.sub.1 =H, Hal, alk, alk-O-, CF.sub.3 ; R.sub.2 =--COOalk; --CONHR.sub.5 (R.sub.5 =H or various substituents); R.sub.3 =H, alk, --COOalk; R.sub.4 =H, Ac, alk, --CONHR.sub.6 (R.sub.6 =H or various substituents), and acid addition salts, except certain known compounds, are useful in treating anoxia and depression and in psychotropic therapy. They are prepared from tryptamine or a derivative thereof by reaction thereof with a pyruvic ester or 3-ethoxycarbonyl-1,2-dioxo-1-ethoxypropane to form compounds in which R.sub.4 is H and R.sub.2 is --COOalk. These compounds are reacted with amines, isocyanates or usual N-acylating or N-alkylating reagents to prepare the other compounds.
