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.

Phenethanolamine derivatives in the (+)-erythro form of the formula: ##STR1## wherein X represents a halogen atom, are new compounds useful in therapy.
摘要:
Compounds of the general formula: ##STR1## wherein R.sub.1 represents hydrogen, chlorine or methoxy, R.sub.2 represents hydrogen, methyl or benzyl, and R.sub.3 and R.sub.4 represent hydrogen, or R.sub.3 represents methyl and R.sub.4 represents hydrogen, or R.sub.3 represents hydrogen and R.sub.4 represents methyl, with the exception of those compounds wherein R.sub.1, R.sub.3 and R.sub.4 each represent a hydrogen atom simultaneously, are new therapeutically useful compounds; they possess an antianoxic activity.
