摘要:
This invention relates to a process for the preparation of purified bacterial membranal proteoglycans. The process comprises at least one step in which crude proteoglycans are treated in aqueous medium with a base or a hypobromite, followed by elimination of the excess reactant and the insoluble residue, the purified proteoglycans being present in aqueous solution. The thus obtained purified proteoglycans may be used as immunity adjuvants in vaccines without causing side-effects such as pyrogenic reactions.

The present invention relates to 2'-(ortho-chlorobenzoyl)-4'-chloroglycylanilides, compositions thereof, and their use as medicaments, e.g., as anxiolytic agents.The compounds of the invention have the general formula I ##STR1## in which R represents hydrogen or alkyl,R.sub.1 and R.sub.2 may be identical or different and are selected from hydrogen, alkyl, hydroxyalkyl, alkenyl, and alkynyl, possibly substituted by alkyl, and cycloalkyl having three to six members, possibly substituted by alkyl, with the proviso that, when one of R.sub.1 and R.sub.2 represents hydrogen, the other is not lower alkyl or hydroxyalkyl; and with the further proviso that R.sub.1 and R.sub.2 may not simultaneously represent either hydrogen or lower-alkyl. R.sub.1 and R.sub.2 may furthermore form, with the nitrogen atom to which they are connected, a nitrogen heterocycle possibly containing a second heteroatom selected from oxygen and nitrogen.

The invention concerns new chemical compounds which can be used as medicaments, their preparation, and pharmaceutical compositions, and method of treating therewith.The new chemical compounds have the general formula ##STR1## in which X, which is in 7 position, represents a halogen atom or a trifluoromethyl group.The medicaments containing these active principles may be used in the treatment of various pains, i.e., as analgesics.
摘要:
A process for obtaining a plasminogen activator involves treating an acetone extract powder of organs of animals, such as the lungs and kidneys of pigs, calves, bullocks, horses, lambs or sheep or the ovaries of porcine, bovine or ovine animals, by suspension in an aqueous saline solution, taking up the precipitate obtained in an aqueous saline solution of greater ionic strength and lower pH-value, decanting the solution and precipitating therefrom at acidic pH by adding a salt or an organic solvent, further taking up the precipitate obtained in water or a saline solution, followed by repeated precipitation by adding a salt at a somewhat higher pH-value, finally taking up the precipitate obtained in water and dialyzing the solution, and optionally purifying the solution obtained.The activator obtained may be used as a medicament.
摘要:
The present invention relates to new chemical products which are useful as hypolipemizing and hypocholesterolemizing agents.The new compounds are derivatives of phenoxy isobutyric acid of the general formula ##EQU1## wherein: A is a lower-alkylene bridge of 2 to 6 carbon atoms, either linear or branched,X is a halogen atom,R = h or lower-alkyl,The N of the pyridyl ring can be replaced by an N-oxide, or the compounds can be in the form of their pharmaceutically-acceptable acid addition salts.Pharmaceutical compositions containing these active principles are useful for hypolipemizing and hypocholesterolemizing purposes, e.g., in the prevention and treatment of atherosclerosis and its consequences.

N--C.sub.1 to C.sub.4 -alkyl-5-bromo-ortho-cresotamides; their use as anticonvulsants. 5-Bromo-ortho-cresotamide may also be named 5-Bromo-2-hydroxy-3-methyl-benzamide.
摘要:
The present invention concerns new derivatives of 1-aryl 2-aminomethyl cyclopropane carboxylates (Z), their preparation and their use as useful drugs for the treatment of various pains.The new derivatives of the present invention have the general formula I ##STR1## in which: R represents a hydrogen or halogen atom, a C.sub.1 to C.sub.4 lower alkyl group, a C.sub.1 to C.sub.4 lower alkoxy group, or a nitro, amino, sulfamoyl or hydroxy group;n represents the values 1, 2 or 3;(R).sub.n may together with the benzene ring also form the naphthyl group;R.sub.1 represents a linear or branched C.sub.1 to C.sub.5 alkyl or alkenyl group or an aryl or benzyl group;R.sub.2 and R.sub.3 represent a hydrogen atom, a linear or branched C.sub.1 to C.sub.5 alkyl, alkenyl, alkynyl, hydroxyalkyl, alkoxyalkyl, carboxyalkyl or dialkylaminoalkyl group or an aryl, arylalkyl or cycloalkyl group;R.sub.2 and R.sub.3 possibly also forming a heterocycle of 5 or 6 members with the adjacent nitrogen atom,provided however that when R.sub.1 represents the ethyl radical and R represents a hydrogen atom, R.sub.2 and R.sub.3 cannot simultaneously represent a methyl radical.
摘要:
The present invention concerns a novel process for the production of new chemical compounds of the general formula: ##STR1## in which: R.sub.1 and R.sub.2 may be identical or different and represent a hydrogen or halogen atom or else a lower alkyl, lower alkoxy, nitro or acetyl group andR represents a lower alkyl or lower aralkyl group, such as benzyl.These compounds are useful in therapy for the treatment of hypertension and cardiac arrhythmia.The novel process involves reaction of a 2-hydroxymethyl-1,4-benzodioxan with epichlorohydrin to produce an intermediate glycidyl ether, which is then reacted with a primary amine to produce the final 3-amino-1-[(1,4-benzodioxan)-2-yl-methoxy]-2-propanol or an acid addition salt thereof.
