CA 2318221

The present invention relates to sulfonamide derivatives of formula (I), in which R1, R2, R4, R5 and R6 have the meanings indicated in the claims, their physiologically tolerable salts and their prodrugs. The compounds of the formula (I) are valuable pharmaceutical active compounds. They are vitronectin receptor antagonists and inhibitors of cell adhesion and inhibit bone resorption by osteoclasts. They are suitable, for example, for the therapy and prophylaxis of diseases which are caused at least partially by an undesired extent of bone resorption, for example of osteoporosis. The invention furthermore relates to processes for the preparation of compounds of the formula (I), their use, in particular as pharmaceutical active ingredients, and pharmaceutical preparations comprising them.

La présente invention concerne des dérivés de sulfamide de la formule (I) dans laquelle R?1¿, R?2¿, R?4¿, R?5¿ et R?6¿ ont les significations indiquées dans les revendications; l'invention concerne également leurs sels physiologiquement tolérables et leurs promédicaments. Les composés de la formule (I) représentent des composés actifs du point de vue pharmaceutique. Ils constituent des antagonistes de récepteur de vitronectine et des inhibiteurs d'adhérence cellulaire et inhibent la résorption osseuse par des ostéoclastes. Ils sont indiqués, par exemple, pour le traitement et la prophylaxie d'affections provoquées au moins en partie par une étendue non voulue d'une résorption osseuse, par exemple de l'ostéoporose. L'invention concerne en outre des procédés de préparation de composés de la formule, leur utilisation, notamment comme ingrédients actifs du point de vue pharmaceutique, ainsi que des préparations pharmaceutiques les contenant.
