Definitions

  • the present invention relates to new carboxylic acid derivatives, their preparation and use.
  • Endothelin is a 21 amino acid peptide that is synthesized and released by vascular endothelium. Endothelin exists in three isoforms, ET-1, ET-2 and ET-3. In the following, "endothelin” or “ET” means one or all isoforms of endothelin. Endothelin is a potent vasoconstrictor and has a strong effect on vascular tone. This vasoconstriction is known to be caused by the binding of endothelin to its receptor (Nature, 332, 411-415, 1988; FEBS Letters, 211, 440-444, 1988 and Biochem. Biophys. Res.
