Abstract
Derivatives of 7H-1,3,4-thiadiazolo-[3,2-a]-pyrimidin-7-one-5-carboxylic acid having basic substituents in the 2-position, the alkyl esters and/or pharmaceutically useable salts of these compounds are new substances having immunstimulating properties, being especially valuable for antiinfectious therapy in mammals including man. The new products are prepared by reacting 2-amino-5-(basically substituted)-1,3,4-thiadiazoles with dialkylacetylenedicarboxylates and splitting the ester grouping in the obtained compound if desired and/or forming pharmaceutically acceptable salts.
