The present invention relates to inhibitors of the Wnt signalling pathways of general formula (I) as described and defined herein, to methods of preparing said compounds, to intermediate compounds useful for preparing said compounds, to pharmaceutical compositions and combinations comprising said compounds and to the use of said compounds for manufacturing a pharmaceutical composition for the treatment or prophylaxis of a disease, in particular of a hyper-proliferative disorder, as a sole agent or in combination with other active ingredients.
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.
