Definitions
- the invention relates to the use of derivatives and guanabenz guanabenz to manufacture drugs to restore addressing "proteins from the endoplasmic reticulum to the plasma membranes.
- the functional organization of the eukaryotic cell is based on an elaborate system of membrane compartments or organelles (nucleus, endoblastic reticulum, Golgi apparatus, endosomes) with their own protein and lipid composition.
- the targeting of proteins in the cell is a set of molecular mechanisms to ensure, during protein synthesis, the correct folding, maturation and localization of functional proteins.
- Cystic fibrosis (CF: Cystic Flbrosis) is the most common recessive genetic, autosomal, and lethal disease in European and North American populations.
- the CF gene (locus 7q31) encodes the trans-membrane protein named CFTR (for Cystic Fibrosis Transmembrane Conductance Regulator). This protein is a chloride channel located in the apical plasma membrane of pulmonary and digestive epithelial cells in healthy individuals. Although there are more than 1000 mutations of the CFTR protein, the most common mutation (70% of patients) is the deletion of a phenylalanine in the NBF1 domain. position 508 (delF508).
- CFTR is responsible for the trans-epithelial transport of water and electrolytes, and allows in a healthy individual, the hydration of the pulmonary airways, the proper digestive secretory function and exocrine glands in general.
- One of the keys to a treatment of this disease, and in general of any pathology related to such addressing problems, consists of a re-addressing of the CFTR delF508 protein to the apical membrane of the cells. Once at the membrane, CFTR delF508 transport activity can be stimulated by physiological agonists.
- guanabenz long used clinically for the treatment of hypertension, was able to activate wild-type CFTR and mutated forms and to cause a membrane relocation of the delF508-protein. CFTR thus restores its trans-membrane transport capacity.
- the invention therefore aims to provide a new use of these derivatives to manufacture drugs for the treatment of cystic fibrosis and diseases related to a defective targeting of proteins in cells, in particular as indicated above.
- the derivatives used in accordance with the invention correspond to formula (I):
- R H or Cl and the phenyl group comprises at least two substituents, or a pharmaceutically acceptable salt thereof.
- guanabenz as used in the specification and claims, corresponds to the compound of formula (II):
- the active ingredients used in therapeutically effective amounts, are mixed with the pharmaceutically acceptable carriers for the chosen mode of administration.
- These vehicles can be solid or liquid.
- the drugs are, in the form of capsules, tablets, dragees, capsules, pills, drops, syrups and the like. Such drugs may contain from 1 to 100 mg of active ingredient per unit.
- the drugs are in the form of sterile or sterilizable solutions.
- They can also be in the form of emulsions or suspensions.
- the medicaments of the invention are more particularly administered in the form of aerosols.
- the doses per unit dose may vary from 1 to 50 mg of active ingredient.
- the daily dosage is chosen so as to obtain a final concentration of not more than 100 ⁇ M guanabenz derivative in the blood of the treated patient.
- Other features and advantages of the invention are given in the results reported below to illustrate the invention.
- FIGS. 1 and 2 represent, respectively: FIGS. 1A and 1B: the activation of delF508-CFTR in CF15 cells after treatment with guanabenz;
- Figure 2A the dose-response relationship observed with a 2 hour treatment with guanabenz;
- FIG. 2B the pharmacological profile of CFTR channels in CF15 cells after 2 hours of incubation with guanabenz.
- CHO-WT Cells CHO (Chinese Hamster Ovary) cells are fibroblasts that have been transfected with the wild-type CFTR gene (CFTR-WT). These cells will therefore overexpress the CFTR protein.
- CF15 cells CF15 cells are human nasal epithelial cells that express the ⁇ F508-CFTR gene.
- Culture medium Medium DMEM + HAM F12 + 10% FCS + 0.6% penicillin / streptomycin + growth factors (insulin 5 ⁇ g / ml, transferrin 5 ⁇ g / ml, epinephrine 5.5 ⁇ M, adenine 0.18 mM, EGF 10 ng / ml, T3 2 nM, hydrocortisone 1, 1 ⁇ M).
- Calu-3 Cells Calu-3 cells are human lung epithelial cells that express the wild-type CFTR gene.
- Culture medium DMEM / F12 medium with glutamax + 7% fetal calf serum + 1% penicillin / streptomycin. M2. immunostaining
- Immunolabeling allows to visualize the cellular localization of the CFTR protein by means of a primary anti-CFTR antibody (Ac), then a Cy3 fluorophore-labeled primary anti-body secondary antibody.
- the cells are first seeded on slides in appropriate culture medium. 3 washings with TBS (NaCl: 157 mM, Tris base: 20 ⁇ M, pH 7.4) of 5 min each are carried out. The cells are then fixed by adding TBS-paraformaldehyde (3%) for 20 min.
- the slats can be mounted on the slide after the last 3 washes with TBS of 5 min. Slides are observed under a confocal microscope (Bio-Rad) by laser excitation at appropriate wavelengths. In order to differentiate the labeling between Cy3 and Topro3 the fluorescence color of Topro3 has been changed to blue (color of the nuclei). M3. Efflux of radiotracers
- the cells are cultured on 24-well plates in a suitable medium.
- 2 rinses with efflux medium NaCl: 136.6 mM, KCl: 5.4 mM, KH 2 PO 4 : 0.3 mM, NaH 2 PO 4 : 0.3 mM, NaHCO 3 : 4.2 mM
- efflux medium NaCl: 136.6 mM, KCl: 5.4 mM
- KH 2 PO 4 0.3 mM
- NaH 2 PO 4 0.3 mM
- NaH 2 PO 4 0.3 mM

- CaCl 2 1.3 mM
- MgCl 2 0.5 mM
- MgSO 4 0.4 mM
- HEPES 10 mM
- D-glucose 5.6 mM
- the cells are incubated with 500 ⁇ l of loading (1 ⁇ Ci / ml of 125 INa) for 30 min for CHO-WT or 1 hour for CF15 and Calu-3. Iodide equilibrates on both sides of the cell membrane.
- the robot (MultiPROBE, Packard) performs the following steps: the loading medium is rinsed with medium • efflux to remove extracellular radioactivity. The supernatant is collected every minute in hemolysis tubes and the medium is replaced by an equivalent volume
- R radioactive iodide
- HiIrT 1 [In ( 125 I t x ) -In ( 125 I t 2 )] / (t-t 2 ) with 125 I ti: cpm at time ti; 125 I t 2 : cpm at time t 2 .
- This iodide stream is represented as a curve.
- M4 Cytotoxicity test The MTT toxicity test is a colorimetric test based on the ability of mitochondrial dehydrogenases to metabolize MTT (yellow tetrazolium salt) to formazan.
- the absorbance proportional to the converted dye concentration, can then be measured spectrophotometrically.
- the cells are incubated on 96-well plates in the presence of the agent to be tested for 2 hours. 3 controls are performed: 100% living cells: cells without agents; 0% living cells: cells left in the open air; white: medium without cell.
- the cells are rinsed with RPMI medium without phenol red so that the color of the medium does not interfere with the absorbance measurements. They are then incubated for 4 h with 100 ⁇ l of RPMI solution supplemented with MTT (0.5 mg / ml). The medium is then removed, the addition of 100 .mu.l of DMSO makes it possible to solubilize the converted dye (formazan).
- the delF508-CFTR protein addressing study is carried out by combining pharmacology, cell imaging, biochemical and electrophysiological assays on pulmonary human epithelial CF15 cells homozygous for delF508 deletion.
- FIG. 1 the results of the activation of delF508-CFTR in CF15 cells after treatment with guanabenz are reported (the results concerning an anti-prion compound, namely 6AP (for 6-amino-phenanthridine) are also given ).
- the iodide efflux experiments are carried out after 2 h of incubation with 100 .mu.m of the test compound or in the absence of this compound.
- CF 15 cells, treated for 24 h at 27 ° C. were used as a positive control and untreated CF15 cells as a negative control (37 ° C.).
- Figure 2A Dose-response results after 2 h of guanabenz treatment are reported in Figure 2A.
- Figure 2B shows the pharmacological profile of CFTR channels in CF15 cells after 2 h of incubation with 100 ⁇ M guanabenz.
- the work carried out has shown that a treatment of CF15 cells (F508del / F508del) with guanabenz makes it possible to relocate the mutated F508del-CFTR protein to the membrane.
- guanabenz allows the re-addressing of the F508del-CFTR protein after 2 h of treatment with a 40 ⁇ M EC 50 .
- these experiments revealed a competition between guanabenz and MG132, a proteasome inhibitor, and between guanabenz and swainsonine, a mannosidase inhibitor.
- guanabenz allows the relocation of F508del-CFTR protein by inhibition of degradation pathway and / or that it is possible to modulate the glycosylation state of the protein inhibiting its interaction with chaperones of the endosplasmic reticulum (ER).
