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.
