Abstract:
The present application relates to pharmaceutical compositions incorporating as active ingredient p.chlorohippuric acid or one of its mineral or organic base addition salts.The pharmaceutical compositions are those adapted for parenteral or oral administration. They may include another active ingredient.The present application also extends to therapeutic methods for using the said pharmaceutical compositions namely for protecting the gastric mucosa from acid hypersecretion, ulcers from therapeutic origin and for protecting the liver from toxic aggressions.
Abstract:
This application relates to benzenesulphonamides and more specifically to 1-acylamino 2- alcoxy or alcenyloxy 5-morpholinylsulfonyl benzenes and their salts with a mineral or organic acid. It also relates to processes for producing these compounds.The disclosed compounds are useful for stimulating gastric evacuation while inhibiting emisis and gastric secretion in warm-blooded animals.
Abstract:
Process for the industrial synthesis of (2S,3 7aS)-2-carboxyperhydroindole by reduction of 2-carboxindole or of one of its esters to (R,S)-2-carboxyindo or of one of its esters which, after saponification, converted into the acid, the S isomer cf (R,S)-2-carboxyindoline being obtained by precipitation from the mixture of the two (R) and (S) isomers, in the presence of (+) methylbenzylamine, (S)-2-carboxyindoline being in its turn subjected to catalytic hydrogenation to give (2S, 3aS,7aS)-2-carboxyperhydroindole, after separation of (2S,3aR,7aR) isomer by crystallization.Application to the synthesis of carboxyalkyl d peptides capable of being employed in therapeutics.

Abstract:
Process for the industrial synthesis of perindopril, in which (2S,3aS,7aS)-2-carboxyperhydroindole is condensed with N-[(S)-1-carbethoxybutyl]-(S)-alanine after protection of the carboxyl group, the product resulting from the condensation being then subjected to deprotection of the carboxyl carried by the heterocyclic ring.The (2S,3aS,7aS)-2-carboxyperhydroindole and N-[(S)-1-carbethoxybutyl]-(S)-alanine are themselves obtained in excellent conditions from 2-carboxyindole and from L-alanine respectively, both available on an industrial scale.
