Definitions

  • the present invention relates to new carboxylic acid derivatives, their preparation and use.
  • Endothelin is a peptide made up of 21 amino acids that is synthesized and released by vascular endothelium. Endothelin exists in three isoforms, ET-1, ET-2 and ET-3.
  • endothelin or “ET” means one or all isoforms of endothelin.
  • Endothelin is a potent vasocon-
  • vasoconstriction is known to be caused by the binding of endothelin to its receptor (Nature, 332, 411-415, 1988; FEBS Letters, 231, 440-444, 1988 and Biochem. Biophys. Res. Commun., 154, 868-875, 1988).
  • endothelin causes persistent vascular contraction in peripheral, renal, and cerebral blood vessels, which can lead to disease.

  • ET A and ET B receptor 35 are currently described in the literature (Nature 348, 730 (1990), Nature 348, 732 (1990)). Accordingly, substances that inhibit the binding of endothelin to the two receptors should antagonize the physiological effects of endothelin and should therefore be valuable pharmaceuticals.

  • ET A -specific antagonists here as antagonists whose affinity for the ET A receptor is at least ten times higher than their affinity for the ET B receptor.
