Abstract: The invention relates to 4-acylamino-1-azaadamantanes represented by general formula (I): ##STR1## wherein R represents an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group, useful in particular, for the treatment of cardiovascular diseases.

Abstract: (+)-5-Methyl-10,11-dihydro-5H-dibenzo[a,d]-cyclohepten-5,10-imine, and its pharmaceutically acceptable salts is useful as an anxiolytic, antidepressant, anticonvulsant, muscle relaxant and in the treatment of mixed anxiety-depression, minimal brain dysfunction and extrapyramidal disorders such as Parkinson's disease. The racemate of the compound is produced by a four-step synthetic process in about 65% yield from 5H-dibenzo[a,d]cyclohepten-5-one.

Abstract: 5-Substituted-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imines, derivatives and pharmaceutically acceptable salts thereof are useful as anticonvulsants.

Abstract: Dibenzo[a,d]cycloocten-5,12-(and 6,12)-imines, derivatives and pharmaceutically acceptable salts thereof are useful as anxiolytics, antidepressants, anticonvulsants, muscle relaxants and in the treatment of mixed anxiety-depression, minimal brain dysfunction and extrapyramidal disorders such as Parkinson's disease.

Abstract: A pyrido[3,2,1-jk]carbazol derivative represented by the formula (I) ##STR1## wherein R represents a hydroxy group, an alkoxy group which may be substituted with a halogen atom or with a 4-methyl-1-piperidinyl group, a hydrazino group or a ##STR2## group, Y represents an alkoxy group, a halogen atom, a nitro group, an amino group, an alkanoylamino group or alkyl group, and n is 0, 1 or 2; and the pharmaceutically acceptable salts thereof having antimicrobial, anti-cancer and antiviral activities, and a process for preparing the same.

Abstract: 2,4a-Ethanobenz[g]isoquinolin-5(1H)-one derivatives are described which are useful as analgesic and anti-fertility agents.

Abstract: 10,11-Dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imines, derivatives and pharmaceutically acceptable salts thereof are useful as antianxiety agents, as muscle relaxants and in the treatment of extrapyramidal disorders such as in Parkinson's disease. They are prepared by treatment of a 5H-dibenzo[a,d]cyclohepten-5-one with ammonia to give the 5-imine, acylation of the imine, treatment of the protected imine with an organolithium to provide the 5-substituted-5-acylamino compound, treatment with acid or base to cause ring closure to a 5-substituted-5,10-acylimino compound followed by removal of the protecting group, either hydrolytically or hydrogenolytically.

Abstract: Benzocycloheptapyridines with an imine bridge in the cycloheptane ring, derivatives and pharmaceutically acceptable salts thereof are useful as antianxiety agents, as muscle relaxants and in the treatment of extrapyramidal disorders such as in Parkinson's disease.

Abstract: Compounds of the tropane (8-azabicyclo[3.2.1]octane) series having an aromatic substituent in the 2-position and a carboalkoxy group in the 3-position are prepared by reacting a tropane-3-carboxylate having a double bond in the 2,3-position with an aryl Grignard reagent. Transformations of the substituent on nitrogen are subsequently effected. Compounds where the 3-carboalkoxy group is in the exo configuration possess hypoglycemic activity, and those where the 3-carboalkoxy group is in the endo configuration possess narcotic antagonist activity.

Abstract: The subject of the invention are dyestuffs of the formula ##STR1## wherein R is hydrogen or a hydrocarbon radicalQ is arylX is .dbd.C(W) -- or .dbd.N--,W is a nitrile ester or amide groups andA represents the remaining members of a heterocyclic radical.The dyestuffs are preferably suitable for dyeing polyester fibres which are dyed in orange, red, violet or bluish shades with good fastness to light.

Abstract: Polycyclic chlorinated amines resulting from cycloadditions useful as insecticides.
