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” denotes 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, 231, 440-444, 1988 and Biochem. Biophys. Res. Commun., 15 ⁇ , 868-875, 1988).
  • endothelin causes persistent vascular contraction in peripheral, renal, and cerebral blood vessels, which can lead to disease.
  • endothelin is involved in a number of diseases. These include: hypertension, acute myocardial infarction, pulmonary hypertension, Raynaud's syndrome, cerebral vasospasm, stroke, benign prostate hypertrophy, atherosclerosis, asthma and prostate cancer (J. Vascular Med. Biology 2, 207 (1990), J. Am. Med. Association 2 £ A, 2868 (1990), Nature i, 114 (1990), N. Engl. J. Med. 221, 205 (1989), N. Engl. J. Med.
  • ET A and ET B receptor At least two endothelin receptor subtypes, ET A and ET B receptor, are currently described in the literature (Nature 348, 730 (1990), Nature 348, 732 (1990)).
