Abstract: Compound of formula (I): wherein: R1 represents hydrogen or wherein A is as defined in the description, R2 and R3 each independently represents alkyl, cycloalkyl, heterocycloalkyl, optionally substituted aryl, optionally substituted heteroaryl, cycloalkylalkyl, heterocycloalkylalkyl, optionally substituted arylalkyl, optionally substituted heteroarylalkyl,or optionally substituted aminoalkyl or R2 and R3, together with the carbon atom carrying them, form cycloalkyl or monocyclic heterocyclic group, substituted or unsubstituted, R40 represents hydrogen or a group selected from optionally substituted alkyl, optionally substituted alkenyl and optionally substituted alkynyl or Q or —V—Q wherein V represents alkylene, alkenylene or alkynylene and Q represents optionally substituted cycloalkyl, optionally substituted aryl, optionally substituted heterocycloalkyl,or optionally substituted heteroaryl, R41 and R5 together form a bond or each represents hydrogen, R6,

Abstract: A compound selected from those of formula (I): ##STR1## in which: A either represents --OR.sub.6, and B represents --CH.sub.2 --X,or, together with B and the carbon atom carrying them, forms an oxygen-containing heterocycle selected from oxirane, 2,2-dimethyl[1,3]dioxolane and [1,3]dioxolan-2-one,and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and X are as defined in the description.

Abstract: The invention relates to novel .beta.-carboline-derived compounds which are benzodiazepine-receptor ligands having an inverse agonist and antagonist effect on benzodiazepines. These compounds are of the formulae: ##STR1## in which: X is O, S, ##STR2## or alternatively, ##STR3## represents the radical --N(R.sub.6)--C(=O)--CH.sub.2 --X, R.sub.1 is a hydroxyl, alkoxy or alkyl radical substituted by a hydroxyl or alkoxy radical,R.sub.2 is a hydrogen atom or an alkyl, hydroxyl, alkoxy, acyloxy or benzyloxy radical, it being possible for said radicals to be optionally substituted,R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are chosen from a hydrogen atom or an alkyl radical optionally substituted by a hydroxyl, alkoxy or alkoxycarbonylmethyl radical,as well as the corresponding tetrahydro derivatives of .beta.-carboline and the quaternary ammonium salts or derivatives of these pharmaceutically acceptable compounds.
