摘要:
The (R) or (S) isomer of acetorphan or N-/(acetylthiomethyl)-2-oxo-1-phenyl-3-propyl/(S) alanine methyl ester is prepared by splitting of racemic acetylthio-3-benzyl-2-propanoic acid by reaction with ephedrin, separation of the enantiomeric salt obtained, then freeing of the acid and coupling with the corresponding amino acid ester. The obtained preparations possess remarkable therapeutic activities and can notably be used as drugs.
摘要:
The present invention relates to a new formulation of an enkephalinase inhibitor, such as racecadotril or dexecadotril, the process for the preparation thereof, and the use thereof in the treatment of diarrhea.
摘要:
Medicament comprising, in a pharmaceutically acceptable vehicle, an anti-psychotic or an antidepressant (A), which, on its own, has an undesirable effect of a gain in body weight or sedation, and an antagonist and/or inverse agonist (B) of the histamine H3 receptor, the antagonist and/or inverse agonist of the histamine H3 receptor being present in a therapeutically effective amount for ensuring at least one of the following three effects: suppression or at least limitation of the undesirable effect of weight gain, suppression or limitation of the undesirable effect on alertness, epilepsy/convulsions, increase in the precognitive effect of the treatment. Use of such an antagonist or inverse agonist for the preparation of a medicament which is to ensure at least one of the said three effects in a patient treated by such an antipsychotic or antidepressant.
摘要:

摘要:
The invention relates to compounds which constitute a class of medicaments which have an anti-inflammatory activity and which act by inhibiting leukotriene A4 (LTA4), and enzyme which is responsible for the biosynthesis of leukotriene LTB4, a major proinflammatory mediator. The invention also relates to therapeutic anti-inflammatory, applications of these compounds as well as for methods of preparing these compounds.
摘要:
Process for the asymmetric synthesis of S-acyl derivatives of 2-mercaptomethyl-3-phenylpropanoic acid of formula (I): characterized in that it comprises the steps consisting in:a) preparing the diol (VI) by reduction of a malonic ester (V) in the presence of a hydride;b) preparing the monoacetates (VII R) or (VII S) respectively;c) subjecting these monoacetates to an oxidation in order to form the acids (IX S) or (IX R);d) saponifying the compounds (IX S) or (IX R) in order to form the hydroxy acids (X S) or (X R);e) thioacylating the hydroxy acids (X S) or (X R) with a mercapto acid R.sub.1 SH (XI), according to a Mitsunobu-type reaction, in order to lead to the desired acids (I R) (I S) respectively and application to the synthesis of N-(mercaptoacyl)amino acid derivatives (II). ##STR1##
