Bis-sulfonamides as endothelin receptor antagonists
摘要:
Modification of the structure of bosentan 1, the first marketed endothelin receptor antagonist (Tracleer(TM)), by introduction of a second sulfonamide function at the alkoxy side chain, led to bis-sulfonamides 2. This allowed to prepare dual ETA/ETB as well as ETB receptor selective antagonists, which could serve as tools to investigate the pharmacological consequences of selective ETB receptor blockade.

The invention relates to novel bis-sulfonamides and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more of those compounds and especially their use as endothelin antagonists.
