Definitions
- the present application relates to compositions and methods for the treatment of intestinal pathologies. It also relates to compositions and methods for regulating the paracellular permeability of the intestinal epithelium.
- the compositions and methods of the invention are based in particular on the use of protease inhibitors modulating the opening of tight junctions of the intestinal epithelium.
- the invention can be used for the preventive or curative treatment of various pathologies, such as functional digestive disorders (TFD), more particularly functional intestinal disorders (TFI), and in particular irritable bowel syndrome (SU also called “Irritable”). Bowel Syndrome ", IBS), hyperalgesia and other abdominal pain, etc., in mammals, especially humans.
- the intestinal epithelium is the center of very important exchanges between the external environment and the organism. These exchanges can take place either through the cells of the epithelium, or through parallel networks.
- the transport of water or electrolytes, or the absorption of small molecules (molecular weight generally less than about 1000 Da) at the level of the gastric, intestinal or colic mucosa is carried out by transcellular route, through epithelial cells or enterocytes.
- the absorption of large molecules and the passage of antigens, toxins or immune cells takes place mainly by the paracellular route, at the level of "tight junctions", which are arranged between the epithelial cells.
- JS epithelial tight junctions
- TJ The epithelial tight junctions
- JS epithelial tight junctions
- These structures provide and control the paracellular transepithelial transport, from the outside to the submucosa, of macromolecules various (allergens, irritants, toxins, microorganisms).
- These structures also allow the migration of immune cells (eg, immunocytes) to the outside (digestive tract).
- Tight junctions are flexible structures made up of a complex assembly of transmembrane proteins (occludins, claudins) and cytoplasmic proteins (zona ocludens proteins ZO-1, ZO-2, ZO-3, proteins AF7, cinguline or 7H6, etc. ), which are associated with elements of the cytoskeleton (myosin, actin filaments, etc.).
- TFD digestive functional disorders
- abdominal pain without elimination disorder can be caused by food allergies or intolerances or manifest as part of celiac disease for example.
- Functional intestinal disorders affect 15 to 20% of the population and result in dyspeptic and / or intestinal symptoms for which no organic cause has so far been identified and which require specific treatment.
- the common characteristic of functional digestive disorders meeting ROME criteria is abdominal pain, present in the postprandial period, whether localized in the upper part (dyspepsia) or in the lower part of the abdomen.
- One particular disorder that affects the lower abdomen is Irritable Bowel Syndrome (SU).
- SU Irritable Bowel Syndrome
- This digestive micro-inflammatory state promotes the sensitization of the endings of the primary afferent neurons and this sensitization could lead to a secondary facilitation of the transmission, to the brain, messages of a nociceptive nature.
- Functional imaging studies indeed indicate characteristic changes in the areas of cortical projection of these nerve messages in subjects with TFD.
- Such a process of sensitizing the intestine to pain can be induced by factors such as stress, pathogens, allergens, enzymes of the trypsin or tryptase type for example, bile salts, xenobiotics, chemical molecules of glycerol type, TNBS or taurocholate for example and / or sequelae resulting from an infection or from a surgical operation.
- the present invention results from the demonstration of the activation, by bacterial proteases released in the colonic lumen, of PAR receptors (proteinase-activated receptors), located on the membranes of epithelial cells, which modulate the opening of tight junctions , this opening can lead to a state of hyperalgesia.
- PAR receptors proteinase-activated receptors
- the bacterial origin of the above-mentioned proteases has been demonstrated by the fact that a 10-day oral treatment with a cocktail of antibiotics destroying the flora reduces the permeability of tight junctions, this being restored by the intracolic perfusion of 'a supernatant of normal colonic content.
- the inventors have also demonstrated that a cocktail of protease inhibitors infused into the colonic lumen reduces the colonic paracellular permeability and the visceral sensitivity to distension.
- the present invention stems from the development of new therapeutic strategies for the treatment of intestinal pathologies, based on a modulation of the para-cellular permeability of the intestinal epithelium using protease inhibitors.
- the present invention provides a therapeutic approach to intestinal pathologies based on the use of protease inhibitors for controlling the opening of tight junctions of the intestinal epithelium.
- protease inhibitors make it possible to modulate the tension of the cytoskeleton of the intestinal epithelial cells or to directly regulate, preferably decrease, or even block, the opening of the tight junctions of the intestinal epithelium.
- This approach therefore makes it possible to control the opening and closing of the tight junctions of the intestinal epithelium, without necessarily resorting to de novo protein synthesis and / or to significant protein and / or structural degradations in the epithelium.
- This strategy makes it possible to regulate the permeability of the intestinal epithelium in a specific, fine and reactive manner, and thus to act on the transfer of allergens, pathogens and / or chemical molecules to the cells of immunity. This strategy is particularly suitable for obtaining a rapid and controllable biological effect over time (reversible).
- results presented below show that a substance capable of loosening the tight epithelial junctions (peptides activating the PAR-2 receptor such as the peptide SLIGRL) triggers delayed hyperalgesia, hypersensitivity to distension and an increase in colonic permeability.
- results presented in the examples also show that the suppression of this increase in paracellular permeability by a protease inhibitor or a mixture (cocktail) of protease inhibitors suppresses or reduces this hyperalgesia characteristic of TFD and in particular SU.
- a first object of the invention therefore lies more particularly in the use of at least one protease inhibitor, for the preparation of a medicament intended for the preventive or curative treatment of functional digestive disorders.
- the invention also relates to such a use for the preparation of a medicament intended for the preventive or curative treatment of hyperalgesia occurring in the context of intestinal pathologies.
- the protease inhibitor is preferably an inhibitor of intracolic proteases.
- Another object of the invention lies in a method of preventive or curative treatment of intestinal pathologies characterized by a state of hyperalgesia, comprising the administration to a subject of an effective amount of at least one protease inhibitor.
- Protease inhibitors appear to work by controlling the opening of tight junctions in the intestinal epithelium. These inhibitors are in particular inhibitors which modulate the tension of the cytoskeleton of intestinal epithelial cells or inhibitors which decrease, or even block, the opening of tight junctions of the intestinal epithelium.
- the invention thus relies on the use of protease inhibitors modulating the tension and the state of contraction of the cytoskeleton of the cells of the intestinal epithelium or preventing an excessive opening of the tight junctions which results in hyperalgesia or hypersensitivity distension of the intestine.
- the proteins making up the tight junctions are associated with the cytoskeleton of the cells they connect. It is proposed in the context of the invention that the voltage of the cytoskeleton or the opening of tight junctions can be modulated in subjects suffering from intestinal diseases or disorders to act in a non-destructive and transient manner on the permeability of their intestinal epithelium. Thus, the contraction of the cytoskeleton must favor the opening of tight junctions, while a relaxation of the cytoskeleton (or an inhibition of the contraction) must favor the closing of the junctions. It is also possible to directly modulate tight junctions, in particular on the proteins constituting them, by reducing or blocking their opening.
- protease inhibitors which modulate the contraction of the cytoskeleton of intestinal epithelial cells (or in particular human) or which control the opening of tight junctions of the intestinal epithelium (in particular human).
- protease inhibitors are used which inhibit or activate or promote the contraction of the cytoskeleton of intestinal epithelial cells.
- a protease inhibitor is considered to modulate the tension of the cytoskeleton when it modulates the opening of tight junctions.
- An inhibitory effect on the contraction or tension of the actin and / or myosin filaments need not be complete or total, but it is enough that it reduces the contraction or the tension of the cytoskeleton sufficiently to reduce the opening of the tight junctions.
- the reduction in the opening of tight junctions preferably corresponds to a minimum reduction of approximately 25%, advantageously of approximately 30%, even more preferably of approximately 50% of the paracellular permeability of the intestinal epithelium.
- Paracellular permeability can be measured using a marker such as 51 Cr-EDTA which, after passing through the blood, is measured in the urine for 24 hours (cf.: example 1).
- the protease inhibitors used are preferably the inhibitors acting on serine proteases and / or metalloproteases. Such inhibitors are particularly active in reducing the action of bacterial proteases on colonic permeability.
- protease inhibitors used are advantageously molecules, which can be in isolated form or in the form of a cocktail, combination, biological extracts, etc. These molecules can be synthetic, semi-synthetic or biological, in particular of animal, viral, plant or bacterial origin.
- protease inhibitors of selective or non-selective inhibitors of serine proteases [serpin and its derivatives, Aprotinin, N-tosyl-L-phenylalanyl chloromethyl ketone (TPCK), dichloroisocoumarin, nexin-1, AEBSF-HC1, Antipain, benzamidine, Leupeptine, TLCK, Ovomucoid, phenylmethyl sulfonyl fluoride (PMSF), PEFABLOC® and soy extracts] and metalloproteases (Amastatin, Arphamenine, Bestatin, Diprotin A, Phosphoramidon) as well as non-specific molecules used as antivirals (amprenavir, indinavir, lopinavir, ritonavir, saquinavir, nelfinavir and atazanavir).
- serine proteases serine proteases
- Protease inhibitors can be used alone or in combination and / or in combination with other active agents, such as, for example, other active substances used in the treatment of irritable bowel syndrome.
- Protease inhibitors are thus optionally used in combination and / or in combination with compounds which decrease or block the opening of tight junctions of the intestinal epithelium, in particular by modulating the tension of the cytoskeleton, or which increase the opening of them.
- the activity of these compounds can be direct or indirect, that is to say directed at the very constituents of the cytoskeleton or at regulators of its tension.
- the compounds acting directly on the tension of the cytoskeleton are preferred.
- or ⁇ . also prefers compounds exhibiting selective activity on cytoskeletal tension, that is to say typically compounds which do not directly affect the structure of the proteins constituting the tight junctions.
- the protease inhibitor according to the invention preferably does not directly affect the structure of the proteins constituting the tight junctions.
- the term “compound” must be taken in a broad sense, that is to say as designating any agent, substance, composition, condition, treatment or process making it possible to modulate the opening tight junctions of the intestinal epithelium. It is advantageously an agent (eg, a molecule) or a combination or association of agents. Examples of such compounds are indicated in international patent application No. WO 03/077893. These include inhibitors of myosin light chain kinase (MLC3).
- MLC3 myosin light chain kinase
- a particular example of selective inhibitors of MLCK is the compound ML-7 ⁇ 1- (5-iodonaphthalene-1-sulfonyl) -1H-hex ⁇ ahydro-1,4-diazepine ⁇ (Makishima M. et al. FEBS Lett. 1991; 287: 175).
- Other examples of such inhibitors are in particular the compound ML-9 (Wilson DP. Et al. T Biol Chem. 2001; 13: 165) or other non-selective: Wortmannin (Warashina A. Xife Sci 2000; 13: 2587 -93), H-7 (Piao Zf et al.
- KT 7692 Warashina A. Life Sci 2000; 13: 2587-93.
- Other targets acting on the tension of the cytoskeleton of compounds which can be used in combination with protease inhibitors are in particular myosin binding proteins, such as for example cingulin, or junction molecules, such as cadherin-E, catenin- ⁇ or desmosomes. Modulating the activity or expression of these proteins makes it possible to regulate the tension of the cytoskeleton, within the framework of the present invention.
- Protease inhibitors can also be used in combination with compounds that inhibit protein synthesis or other molecules that link proteins in the cytoskeleton to proteins in tight junctions.
- mitogen-activated kinase inhibitors MAPKK
- kinase MEK1 or kinase-PI3 such as the compounds PD098,059 ⁇ 2- (Amino -3-methoxyphenyl) - 4H-l-benzo ⁇ yran-4-one ⁇ (Alessi et al. J. Biol. Chem. 1995; 270, 27589) or LY294002 ⁇ 2- (4-Morpholinyl) -8-phenyl-l ( 4H) -benzopyran-4-one ⁇ (Vlahos et al. J. Biol. Chem 1994; 269: 5241).
- MAPKK mitogen-activated kinase inhibitors
- HGF hepatic growth factor
- EGF endothelial growth factor
- IGF-1 or gamma interferon growth factors
- proteins acting on receptors located at the apical pole of epithelial cells can act indirectly on the cytoskeleton.
- Other active agents are, for example, anti-cholinergic compounds, prokinetics, anti-diarrheal agents, modifiers of digestive motility, etc. These different agents can be used in therapeutic combination, and administered in separate, combined, time-spread or concomitant form.
- Another object of the invention thus resides in a product, a cocktail or a pharmaceutical combination comprising at least one protease inhibitor and at least one other active agent selected from anti-cholinergic compounds, prokinetic substances, anti-diarrheal substances, laxatives or modifiers of motor skills, viscerosensitivity (or digestive sensitivity), for combined use, separate or spaced over time.
- the present invention can be used for the treatment or management of pathologies or disorders of the digestive system characterized by a state of hyperalgesia, in particular functional intestinal disorders, chronic inflammatory bowel disease (IBD), intolerances food (allergies, packaging, etc.) characterized by chronic visceral pain.
- IBD chronic inflammatory bowel disease
- irritable bowel syndrome whatever its form (constipation, diarrhea or a combination of the two), but also chronic visceral pain not falling within in the context of SU, such as functional abdominal pain without faecal elimination disorder (F APS: Functional Abdominal Pain) and pain related to food intolerance and celiac disease.
- F APS Functional Abdominal Pain
- the compositions and methods of the invention make it possible to reduce the suffering of the subjects, to attenuate the symptoms or the cause of these disorders.
- the present invention surprisingly demonstrates that the suppression of the increase in paracellular permeability associated with the activation of PAR receptors (for example the PAR-2 receptor) prevents the appearance of visceral hyperalgia.
