Definitions

  • isoenzymes and cathepsins for example B and L represent.
  • Calpains are intracellular, proteolytic enzymes from the group of so-called cysteine proteases and are found in many cells. Calpains are activated by increased calcium concentration, with a distinction between Calpain I or ⁇ -calpain, which is activated by ⁇ -molar concentrations of calcium ions, and Calpain II or m-calpain, which is activated by m-molar concentrations of calcium ions , (P.Johnson, Int. J.Biochem. 1990, 22 (8), 811-22). Today, further calpain isoenzymes are postulated (K.Suzuki et al., Biol. Chem. Hoppe-Seyler, 1995, 376 (9), 523-9).
  • calpains play an important role in various physiological processes. These include cleavages of regulatory proteins such as protein kinase C, cytoskeleton proteins such as MAP 2 and spectrin, muscle proteins, protein degradation in rheumatoid arthritis, proteins when platelets are activated, neuropeptide metabolism, proteins in mitosis and others, the in. MJBarrett et al. , Life Be. 1991, 48, 1659-69 and K.K. ang et al. , Trends in Pharmacol. Be . , 1994, 15, 412-9.

  • muscle proteins protein degradation in rheumatoid arthritis
  • proteins when platelets are activated proteins when platelets are activated

  • Elevated calpain levels were measured in various pathophysiological processes, for example: ischemia of the heart (e.g. heart attack), the kidney or the central nervous system (e.g. "stroke"), inflammation, muscular dystrophies, eye cataracts, injuries to the central nervous system (e.g. rauma), Alzheimer's disease, etc. (see KK ang, above). It is suspected that these diseases are associated with increased and persistent intracellular calcium levels. As a result, calcium-dependent processes are overactivated and are no longer subject to physiological regulation. Accordingly, overactivation of calpains can also trigger pathophysiological processes.
  • calpain inhibitors show cytotoxic effects on tumor cells (0 E. Shhiba et al. 20th Meeting Int. Ass. Ereast Cancer Res., Sendai Jp, 1994, September 25-28, Int. J. Oncol 5 (Suppl.), 1994, 381).

Abstract

L'invention concerne des amides de la formule (I) et leurs formes tautomères et isomères, leurs éventuelles formes énantiomères et diastéréomères ainsi que leurs sels physiologiquement compatibles, où les variables ont la signification suivante : R1 représente alkyle C1-C6, phényle, naphtyle, quinolyle, pyridyle, pyrimidyle, pyridazyle, quinazolyle et quinoxalyle, les cycles pouvant encore être substitués par maximum 2 restes R4, R2 représente (CH2)m-R8, R8 représentant du phényle, cyclohexylindolyle ou indolyle et m vaut 1 à 6, et X représente une liaison, -CH2-, -CH2CH2-, -CH=CH-, -C C-, -CONH-, -, SO2NH, R1 et X ensemble représentent formule (a) et R3 représente de l'hydrogène et CO-NR6R7, R4 représente de l'hydrogène, alkyle C1-C4, ramifié ou non ramifié et O-C1-C4 alkyle; R5 représente de l'hydrogène, alkyle C1-C4, ramifié ou non ramifié et O-C1-C4 alkyle; R6 représente de l'hydrogène, alkyle C1-C6, ramifié ou non ramifié et R7 représente de l'hydrogène, alkyle C1-C6, ramifié ou non ramifié et n vaut 0, 1 ou 2. Les amides de la formule (I) sont des inhibiteurs d'enzymes, notamment de protéases de cystéine, telles que la calpaïne (= protéases de cystéine dépendant du calcium) et ses iso-enzymes et cathépsines, par exemple, B et L.
