Definitions
- isoenzymes and cathepsins for example B and L.
- 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 activation 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 is distinguished (P. Johnson, Int. J. Biochem. 1990, 22 (8), 811-22). Further Calpain isoenzymes are postulated today (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, cytoskeletal proteins such as MAP 2 and spectrin, muscle proteins, protein degradation in rheumatoid arthritis, proteins in the activation of platelets, neuropeptide metabolism, proteins in mitosis and others that are described in .M.J. Barrett et al., Life Sci. 1991, 48, 1659-69 and K.K. Wang et al. , Trends in Pharmacol. Be . , 1994, 15, 412-9.
- regulatory proteins such as protein kinase C, cytoskeletal proteins such as MAP 2 and spectrin
- muscle proteins protein degradation in rheumatoid arthritis
- proteins in the activation of platelets proteins in mitosis and others that are described in .M.J. Barrett et al., Life Sci. 1991, 48, 1659-69 and K.K. Wang et al. , Trends in Pharmacol.
- 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. trauma), Alzheimer's disease, etc. (see KK Wang, 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 (E. Shiba et al. 20th Meeting Int. Ass. Breast Cancer Res., Sendai Jp, 1994, 25th to 28th Sept., Int. J. Oncol. 5 (Suppl.), 1994, 381). Further possible uses of calpain inhibitors are in KK Wang, Trends in Pharmacol. Be . , 1994, 15, 412-8.
- Calpain inhibitors have already been described in the literature. However, these are predominantly peptide inhibitors. Many known reversible inhibitors of cysteine proteases - like calpain, however, are peptide aldehydes, in particular dipeptide and tripepidic aldehydes such as, for example, Z-Val-Phe-H (MDL 28170) (S. Mehdi, Trends in Biol. Sei. 1991, 16 , 150-3). Under physiological conditions, peptidic aldehydes have the disadvantage that, owing to their great reactivity, they are often unstable, can be metabolized quickly and tend to have non-specific reactions which can be the cause of toxic effects (JA Fehrentz and B. Castro, Synthesis 1983, 676-78).
- Peptide ketone derivatives are also inhibitors of
- Cysteine proteases especially calpains.
- ketone derivatives are known as inhibitors in the case of serine proteases, the keto group being activated by an electron-withdrawing group such as CF 3 .
- CF 3 an electron-withdrawing group
- cysteine proteases derivatives with ketones activated by CF 3 or similar groups are little or not effective (MR Angelastro et al., J. Med. Chem. 1990, 33, 11-13).
- Ketones which carry an amino or amido group in the ⁇ -position are also known, but mostly in structures derived from peptides. Thus, in EP 603873, ⁇ -amino residues bearing a heterocycle have been mentioned. ⁇ -Amides have also been described several times: D.L. Flynn et al. J. Am. Chem. Soc.
- JP 06035142 CA 121, 267626
- Benzamide derivatives are described as a photographic material analogous to general structure I, but in R 1 there are heterocycles such as hydantoins or other groups sensitive to oxidation reactions.
- the active ingredients are administered intravenously, for example as an infusion solution.
- calpain inhibitors which have sufficient water solubility so that an infusion solution can be prepared.
- many of the calpain inhibitors described have the disadvantage that they show little or no water solubility and are therefore not suitable for intravenous administration.
- Such active substances can only be applied with auxiliaries which are intended to impart water solubility (cf. R.T. Bartus et al. J. Cereb. Blood Flow Metab. 1994, 14, 537-544).
- these additives for example polyethylene glycol, often have side effects or are even incompatible.
- a non-peptide calpain inhibitor, which is therefore water-soluble without auxiliary substances, would have a great advantage.
- Such inhibitors have hardly been described so far and would therefore show particular advantages.
- Derivatives surprisingly show the possibility of incorporating rigid structural fragments into potent non-peptide inhibitors of cysteine proteases, e.g. Calpain.
- salt bonds with acids are possible in the present compounds of the general formula I, which all carry at least one aliphatic amine radical. This leads to an improved solubility in water and thus the compounds show the desired profile for intravenous application, as is required, for example, in stroke therapy.
- the present invention relates to substituted benzamides of the general formula I.

- the compounds of the formula I can be used as racemates, as enantiomerically pure compounds or as diastereomers. If enantiomerically pure compounds are desired, these can be obtained, for example, by classical resolution using a suitable optically active base or acid with the compounds of formula I or their intermediates. On the other hand, the enantiomeric compounds can also be produced by using commercially available compounds, for example optically active amino acids such as phenylalanine, tryptophan and tyrosine.
- the invention also relates to compounds of the formula I which are mesomeric or tautomeric, for example those in which the keto group of the formula I is present as an enol tautomer.
- the invention further relates to the physiologically tolerable salts of the compounds I, which can be obtained by reacting compounds I with a suitable acid or base.
- suitable acids and bases are listed, for example, in Progress in Pharmaceutical Research, 1966, Birkhäuser Verlag, Vol. 10, pp. 224-285. These include, for example, hydrochloric acid, citric acid, tartaric acid, lactic acid, phosphoric acid, methanesulfonic acid, acetic acid, formic acid, maleic acid, fumaric acid etc. or sodium hydroxide, lithium hydroxide,. Potassium hydroxide and tris.
- a benzoic acid II which is simply obtained from analogous esters by hydrolysis with acids, such as hydrochloric acid or bases such as lithium hydroxide or sodium hydroxide solution, in aqueous solutions or water-solvent mixtures, such as water-alcohols or water-tetrahydrofuran, at room temperature or elevated temperature until a maximum of the boiling point of the solvent are reacted with the corresponding amino alcohols III to give the benzamides IV.

Such as Swern- and Swern-analogous oxidations (TT Tidwell, Synthesis, 1990, 857-70), sodium hypochlorite / Use TEMPO (SL Harbenson et al., See above) or Dess-Martin (J. Org. Chem. 1983, 48, 4155).

- the chalcones are formed by condensation from acetophenones with aldehydes and can optionally be converted into the analog alkyl derivatives by hydrogenation.
- Amides and sulfonamides are prepared analogously to the methods described above from the amines and acid derivatives.
- the benzamide derivatives I contained in the present invention are inhibitors of cysteine proteases, in particular cysteine proteases such as calpains I and II and cathepsins B and L.
- the amides I were measured in this way for the inhibitory action of calpain I, calpain II and cathepsin B.
- Cathepsin B inhibition was analogous to a method by
- calpain inhibitors The inhibitory properties of calpain inhibitors are tested in buffer with 50 mM Tris-HCl, pH 7.5; 0.1 M NaCl; 1mM dithiotreithol; 0.11 mM Ca Cl 2 , the fluorogenic calpain substrate Suc-Leu-Tyr-AMC (25 mM dissolved in DMSO, Bachern / Switzerland) being used.
- Human ⁇ -calpain is isolated from erythrocytes and after several chromatographic steps (DEAE-Sepharose, Phenyl-Sepharose, Superdex 200 and Blue-Sepharose), enzyme with a purity> 95% is obtained, assessed according to SDS-PAGE, Western Blot Analysis and N -terminal sequencing.
- the cleavage of the substrate is linear and the a tocatalytic activity of calpain is low when the experiments are carried out at temperatures of 12 ° C.
- the inhibitors and the calpain substrate are added to the test batch as DMSO solutions, with DMSO not exceeding 2% in the final concentration.
- Calpain is an intracellular cysteine protease. Calpain inhibitors must pass through the cell membrane to prevent the breakdown of intracellular proteins by calpain. Some known calpain inhibitors, such as, for example, E 64 and leupeptin, only poorly cross the cell membranes and accordingly, although they are good calpain inhibitors, show only poor activity on cells. The aim is to find connections with better membrane compatibility. We use human platelets as evidence of the membrane compatibility of calpain inhibitors.
- the platelet-rich plasma was pooled and diluted 1: 1 with platelet buffer (platelet buffer: 68 M NaCl, 2.7 mM KC1, 0.5 mM MgCl 2 x 6 H 2 0, 0.24 mM NaH 2 P0 4 x H 2 0, 12 mM NaHC0 3 , 5.6 mM glucose, 1 mM EDTA, pH 7.4). After a centrifugation and washing step with platelet buffer
- the platelets were adjusted to 10 7 cells / ml.
- the human platelets were isolated at RT.
- SDS sample buffer 20 mM Tris-HCl, 5 mM EDTA, 5 mM EGTA, 1 mM DTT, 0.5 mM PMSF, 5 ⁇ g / ml leupeptin, 10 ⁇ g / ml pepstatin, 10% glycerin and 1% SDS.
- the proteins were separated in a 12% gel and pp ⁇ Osrc and its 52-kDa and 47-kDa cleavage products were identified by Western blotting.
- the 5 polyclonal rabbit antibody anti-Cys-src (pp60 c_rc ) used was purchased from Biomol Feinchemischen (Hamburg). This primary antibody was detected using an HRP-coupled second goat antibody (Boehringer Mannheim, FRG). Western blotting was carried out according to known methods.
- pp60src The cleavage of pp60src was quantified densitometrically, using controls which were not activated (control 1: no cleavage) and 5 plates treated with ionophore and calcium (control 2: corresponds to 100% cleavage).
- the ED 50 value corresponds to the concentration of inhibitor at which the intensity of the color reaction is reduced by 50%.
- LDH lactate dehydrogenase
- calpain also plays a role in apoptotic cell death (MKT Squier et al. J. Cell. Physiol. 1994, 159, 229-237; T. Patel et al. Faseb Journal 1996, 590, 587-597). Therefore, in another model, cell death was triggered with calcium in the presence of a calcium ionophore in a human cell line. Calpain inhibitors must enter the cell and inhibit calpain there to prevent cell death.
- cell death can be triggered by calcium in the presence of the ionophore A 23187.
- 10 5 cells / well were plated in microtiter plates 20 hours before the experiment. After this period, the cells were incubated with different concentrations of inhibitors in the presence of 2.5 ⁇ M ionophore and 5 mM calcium. After 5 hours, 0.05 ml of XTT (Cell Proliferation Kit II, Boehringer Mannheim) was added to the reaction mixture. The optical density is determined approximately 17 hours later, according to the manufacturer's instructions, in the Easy Reader EAR 400 from SLT. The optical density at which half of the cells died is calculated from the two controls with cells without inhibitors which were incubated in the absence and presence of ionophore.
- a number of neurological diseases or mental disorders result in increased glutamate activity, which leads to states of overexcitation or toxic effects in the central nervous system (CNS). Glutamate mediates its effects via various receptors. Two of these receptors are classified according to the specific agonists NMDA receptor and AMPA receptor. Antagonists against these effects mediated by glutamate can thus be used to treat these diseases, in particular for therapeutic use against neurodegenerative diseases such as Huntington's and Parkinson's disease, neurotoxic disorders after hypoxia, anoxia,
- Ischemia and after lesions as they occur after stroke and trauma, or also as anti-epileptics (see Medicinal Research 1990, 40, 511-514; TIPS, 1990, 11, 334-338; Drugs of the Future 1989, 14, 1059 -1071).
- EAA Extracerebral application of excitatory amino acids
- EAA antagonists central active ingredients
- EAA antagonism in vivo that the substances can be used therapeutically against such CNS diseases.
- an ED 50 value was determined, in which 50% of the animals become free of syptoma by a fixed dose of either NMDA or AMPA by the previous ip administration of the measuring substance.
