Abstract: Compounds of general formula ##STR1## wherein R.sup.1 represents a member selected from the group consisting of (a) an unsubstituted at most binuclear aryl group having from 6 to 10 carbon atoms, such groups substituted by from 1 to 3 equal or different radicals selected from the group consisting of alkyl, halogenoalkyl, alkoxy, dialkylamino each having up to 4 carbon atoms in the alkyl moiety, halogen phenyl, carboxyl, cyano, nitro and hydroxy groups,(b) a 5- to 6-membered heteroaromatic ring wherein the heteroatom is selected from nitrogen, oxygen and sulfur atoms and such rings anellated to a benzene nucleus;R.sup.2 represents a member selected from the group consisting of hydrogen, alkyl having up to 3 carbon atoms, phenyl, cycloalkyl having up to 6 carbon atoms in the ring and cycloalkyl bearing a hydrocarbon bridging radical having up to 2 carbon atoms;R.sup.3 represents hydrogen, hydroxy or acyloxy;R.sup.4 and R.sup.

Abstract: The present invention relates to pharmacologically valuable new benzophenone derivatives having a pronounced sedative action on the central nervous system and some of which also possess muscle-relaxing and aggression-inhibiting properties. These new derivatives have the structural formula ##STR1## and the pharmaceutically-acceptable acid-addition salts thereof in which R.sub.1 and R.sub.2 are substituents selected from the group consisting of hydrogen, saturated and unsaturated alkyl groups having 1-4 carbon atoms; R.sub.3 is selected from the group consisting of --COOC.sub.3 H.sub.7, --COOC.sub.4 H.sub.9, --COOC.sub.6 H.sub.5, --C.sub.6 H.sub.5, ##STR2## whereby R.sub.4 is an aliphatic radical with 1 to 4 carbon atoms or phenyl and Y is an oxygen or sulfur atom; if m is O R.sub.3 is further selected from the group consisting of --COOCH.sub.3 and --COOC.sub.2 H.sub.

Abstract: The present invention relates to pharmacologically valuable new benzophenone derivatives having a pronounced sedative action on the central nervous system and some of which also possess muscle-relaxing and aggression-inhibiting properties. These new derivatives have the structural formula ##SPC1##And their addition salts, in whichR.sub.1 and R.sub.2 are substituents selected from the group consisting of hydrogen, alkyl having 1-5 carbon atoms, alkenyl having 2 to 4 carbon atoms, alkinyl having 2 to 4 carbon atoms or .beta.-bromoallyl (--CH.sub.2 --CBr = CH.sub.2) ; R.sub.3 is --CN; n is an integer selected from 1 and 2; and m is an integer selected from 1, 2 and 3, wherein the rings A and B may be substituted, ring A being substituted preferably with a halogen such as chlorine or with nitro, trifluoromethyl, methyl, methoxy or methylmercapto, preferably in the 5 position, and ring B being preferably substituted in the 2' position with chlorine or fluorine. The radical R.sub.
