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.
  • 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, 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.
  • 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 4, 2868 (1990), Nature ll !, 11 (1990), N. Engl. J. Med. 322., 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)). Accordingly, substances that inhibit the binding of endothelin to one or both receptors should antagonize the physiological effects of endothelin and should therefore be valuable pharmaceuticals.
