Abstract: Carcinostatic products are formed by coupling, by covalent bonding, the A chain of ricin with an antibody which is capable of selectively recognizing a given antigen at the surface of cancerous cells. Such products can be made by the formation of a disulphide bridge between the free thiol group in the A chain of ricin and an immunoglobulin or immunoglobulin fragment into which a thiol group or an activated disulphide group has been introduced. The A chain of ricin and the immunoglobulin are carefully purified before use.

Abstract: The present invention relates to phenoxypropane having the formula ##STR1## in which R.sup.1 and R.sup.2 are like or unlike and each is an alkyl group having 1-4 carbon atoms, R.sup.3 is hydrogen or an alkyl group having 1-4 carbon atoms, R.sup.4 is a halogen atom, preferably fluorine, chlorine or bromine, including their optical isomers and also their addition salts with acids.These compounds are of therapeutic value in the treatment of cardiovascular conditions.The invention also relates to methods of synthesis of these products including a synthesis which involves the production, as a intermediate of an 8-aza-4,9-dioxa-2,3-benzo-bicyclo-[4,2,1]-octane having the formula ##STR2## in which R.sup.1 and R.sup.4 are as above defined.

Abstract: Talampicillin 2-methoxyphenoxyacetate; a process for its preparation by acid hydrolysis of the metampicillin phthalidyl ester in a biphasic aqueous-organic solvent and treatment of the resulting aqueous phase with an alkali metal salt of the 2-methoxyphenoxyacetic acid; and pharmaceutical compositions containing said talampicillin 2-methoxyphenoxyacetate as an active ingredient.

Abstract: The present invention relates to a treatment of the "hyperkinetic syndrome" in children, wherein a medicine containing between 50 and 200 mg of 3-morpholino-ethylamino 4-methyl 6-phenylpyridazine is administered daily to patients, by oral route.

Abstract: Novel derivatives of midecamycine, of the formula: ##STR1## wherein X represents an oxygen atom or a sulphur atom, R.sub.1 represents a straight or branched alkyl group, an alkenyl group or an aryl group, R.sub.2 represents a hydrogen atom or a lower acyl group, the dotted lines represent the possible presence of double bonds, it being understood that the 2 double bonds at the 10,11 position on the one hand and the 12,13 position on the other either exist simultaneously or neither of them exists, which give by oral administration plasma rates which are higher than midecamycine and which lack its bitter taste, together with their process of preparation.

Abstract: Compounds having psychostimulant, antispasmodic, hypotensive and analgesic properties are disclosed. The compounds have the formula: ##STR1## in which R.sup.2 is selected from the group consisting of a hydrogen atom and a halogen atom;R.sup.1 is selected from the group consisting of a cyclohexyl group and a phenyl group, and is a cyclohexyl group when R.sup.2 is a halogen atom;A is selected from the group consisting of CH.sub.2 CH.sub.2 and CH.dbd.CH groups; andNr.sup.3 r.sup.4 is selected from the group consisting of an alkylamino group, a dialkylamino group and a heterocyclic ring containing from 5 to 7 atoms in the ring, said ring optionally having one or more sbustituents and optionally containing a second hetero-atom; and acid addition salts of said compounds.

Abstract: A process for the manufacture of benzodiazepine derivatives which comprises reacting 2-amino-5-chloro-benzophenone with a primary amine H.sub.2 N--R.sub.1 to give an imine which is reacted with an amino-ester ##STR1## to give a ketimine said ketimine being then converted to a benzodiazepine derivative.
