Definitions
- the present invention relates to the use of prenyltransferase inhibitors to prepare a medicament intended to treat pathologies which result from the membrane fixation of heterotimeric G protein.
- diseases include in particular diseases linked to the following biological functions or disorders: smell, taste, perception of light, neurotransmission, neurodegeneration, functioning of the endocrine and exocrine glands, autocrine and paracrine regulation, blood pressure, embryogenesis, viral infection, functions immunology, diabetes and obesity.
- the heterotrimeric G protein coupled to receptors with 7 trans-membrane domains is a mediator of extracellular information towards the interior of the cell.
- Several intracellular effectors of protein G are identified such as adenylate cyclase, phospholipase C or even ion channels (cf. Gilman, A.G., Biosci. Rep. 15, 65-97 (1995)).
- adenylate cyclase The activity of adenylate cyclase is modulated by the various G proteins (Gs, Gi, Gq, Go) which thus regulate the biosynthesis of cyclic AMP (cAMP). So we know that for
- the protein G is transiently in a heterotrimeric form, form in which the monomer constituted by an ⁇ subunit is associated with the dimer constituted by the ⁇ and ⁇ subunits. It is also known that for protein G to be functional, it must be fixed by its ⁇ subunit to the membrane, this fixing being possible when the ⁇ subunit is prenylated. It is also known that for protein G to be functional, it must be fixed by its ⁇ subunit to the membrane, this fixing being possible when the ⁇ subunit is prenylated. It is
- the ⁇ subunit may after dissociation modulate the adenylate cyclase and modulate cAMP production.

- the usefulness of prenyltransferase inhibitors in this type of treatment would come from their action which would prevent prenylation at the level of the Ras substrate.
- the prenylation of certain forms of Ras is not modified by prenylation inhibitors (Lerner et al., Oncogene, 15, 1283-1288, 1997).

- MCF-7 cells (2.10) seeded on a 24-well plate are cultured for 5 days in the modified Eagle medium from Dulbecco (Gibco-Brl, Cergy-Pontoise, France) supplemented with 10% inactivated fetal calf serum by heating (Gibco-Brl, Cergy-Pontoise, France), 50,000 units / 1 of penicillin and 50 mg / 1 of streptomycin (Gibco-Brl, Cergy-Pontoise, France), and 2 mM of glutamine (Gibco-Brl, Cergy -Pontoise, France).
- the culture medium is replaced after two washes with a serum-free medium, whether or not supplemented with the agents specified for a time indicated in the various figures.
- Agents activating the production of cAMP are then added at 37 ° C.
- the reaction is stopped after 30 minutes by removing the medium and rapidly adding 200 ⁇ l of 0.1N HCl solution. These extracts are frozen at -80 ° C until they are used.
- the concentration of cAMP is measured using a commercial measurement kit (reference NEK033 from NEN, Les Ulis, France) by following the manufacturer's instructions. Radioactivity is determined by a Gamma counter (Gamma Master-1277, LKB, Turku, Finland).
- the cells were treated on day 1 for 96 hours with increasing concentrations up to 50 ⁇ M of each of the compounds to be tested. At the end of this period, the quantification of cell proliferation is evaluated by colorimetric test based on the cleavage of the tetrazolium salt WST1 by mitochondrial dehydrogenases in viable cells leading to the formation of formazan (Boehringer Mannheim, Meylan, France ). These tests are carried out in duplicate with 8 determinations per concentration tested. For each compound to be tested, the values included in the linear part of the sigmoid were used for a linear regression analysis and used to estimate the inhibitory concentration IC 50 .
- the Mia-PaCa2 cells (400,000) are seeded in Petri dishes (diameter 10 cm) in the modified Eagle medium from Dulbecco (Gibco-Brl, Cergy-Pontoise, France ) supplemented with 10% fetal calf serum inactivated by heating (Gibco-Brl, Cergy-Pontoise, France), 50,000 units / 1 of penicillin and 50 mg / 1 of streptomycin (Gibco-Brl, Cergy-Pontoise, France), and 2 mM glutamine (Gibco-Brl, Cergy-Pontoise, France).
- the compounds are added on day 1 at a concentration of 30 ⁇ M.
- the cells are harvested by scraping on day 3 after two washes with phosphate buffer (PBS, Gibco-Brl, Cergy-Pontoise, France) at 4 ° C.
- the cells are pelleted by centrifugation at low speed (800 g, 5 minutes) .
- the cells are resuspended in buffer A containing Hepes 50 mM pH 7.5, MgCl2 5 mM, EDTA 1 mM, Protease inhibitors (Cocktail tablets, n ° 1836-170, Boehringer Mannheim, Meylan, France).
- the cells are lysed by three cycles of freezing in liquid nitrogen - thawing at 4 ° C.
- the lysate is centrifuged a first time at low speed (1200 g, 5 minutes, 4 ° C) to remove the non-lysed cells.
- the supernatant is centrifuged at high speed (200,000 g, 50 minutes, 4 ° C) to separate the cytosolic fraction and the membrane fraction (pellet).
- the latter is resuspended in buffer A.
- the protein concentration in each fraction is determined by Bradford colorimetric assay (Bio-Rad protein assay, Ivry, France).
- the proteins (20 ⁇ g) are separated by electrophoresis in denaturing polyacrylamide gel (16% gel-tricine, Novex, Prolabo, Fontenay sous Bois) according to the manufacturer's recommendations.
- the proteins thus separated are transferred onto a nitrocellulose membrane (C-hybond, RPN 2020C, Amersham, Les Ulis, France) in semi-dry transfer.
- the ⁇ protein is detected by the antibody T20, sc378, Santa-Cruz, TEBU, Le Perray en Yvelines, France), itself recognized by the second antibody coupled to the peroxidase enzyme.
- Chemiluminescence is obtained with the ECL-Plus system (RPN2132, Amersham, Les Ulis, France). The signal is revealed on Kodak BioMax-light autoradiographic films, Z37358, Sigma, St Quentin, France). The amount of chemiluminescence is proportional to the amount of protein present.
- vaso-intestinal peptide (VIP) and mevastatin were acquired from Bachem (Voisins le Bretonneux, France) and TEBU (Le Perray en Yvelines, France) respectively.
- the compounds of formulas (I), (II) and (III) were supplied by Biomeasure Inc. (Milford, MA, USA). All these compounds were used following the recommendations of their manufacturers.
- VIP has been presented as an extracellular ligand for a G protein-coupled receptor that stimulates cAMP synthesis in human breast cancer cells.
- Figure 1 shows that VIP treatment of human breast cancer cells MCF-7 increases the intracellular amount of cAMP in a concentration-dependent manner.
- the VIP concentration of 10 nM which provides a quasi-optimal cAMP production will be used for the following tests. This concentration is in agreement with the data already published concerning the human breast cancer cell line T47D.
- the compound of formula (I) is known to be a powerful specific famesyltransferase inhibitor, capable of inhibiting farnesylation of ras at concentrations of the order of nanomoles.
- FIG. 2 shows that a 24-hour pre-treatment of MCF-7 cells from in vitro cultures with the compound of formula (I) inhibited, in a concentration-dependent manner, the accumulation of cAMP stimulated by the VIP. Almost complete inhibition was obtained at a concentration of 30 ⁇ M of the compound of formula (I).
- FIG. 3 shows that a treatment of 1 hour with the compound of formula (I) is not sufficient to modify the response to VIP. Despite a weak but reproducible effect after an 8 hour treatment, it is only a 24 hour treatment which gives a clear inhibition of VIP stimulation. The kinetics of action observed are in agreement with that which was expected for a prenyltransferase inhibitor allowing the appearance of non-prenylated forms of protein G subunits.
- the inhibition of stimulation by VIP is not restricted to compounds of structure analogous to that of the compound of formula (I) but can be extended to other inhibitors of prenyltransferases, as shown by the results obtained in particular for compound of formula (H) which is also a powerful farnesyltransferase inhibitor, capable of inhibiting the farnesylation of H-ras of human tumors at concentrations of the order of nanomoles (Table I).
- FIG. 4 shows that the pretreatment of the cells for 24 hours with the compound of formula (I) does not modify the production of cAMP induced by the direct activator of adenylate cyclase, forskolin. This shows that adenylate cyclase itself is not modified by treatment with the compound of formula (I).
- FIG. 5 shows that the pretreatment of the cells for 24 hours with the compound of formula (I) decreases the production of cAMP induced by the direct activator of the ⁇ subunit, the cholera toxin.
- the latter can only be fixed on the heterotrimeric complex (Warner et al., Cell Signal, 8, 43-53 (1996)). This therefore suggests that the pretreatment with the compound of formula (I) prevents the formation of the heterotrimeric complex.
- FIG. 6 shows the results of a western blot performed on untreated cells, cells treated for 48 hours with mevastatin (an inhibitor of mevalonate synthesis), with a geranyl-geranyl transferase inhibitor, the compound of formula (III), or by a pure faraesyltransferase inhibitor, the compound of formula (I).
- the proteins of the cytosolic and membrane fractions of the control or treated cells are separated by denaturing electrophoresis in polyacrylamide gel before being transferred to a semi-solid membrane allowing identification with an antibody (western-blot) directed against all forms of ⁇ proteins.
- the amount of ⁇ complex detected on the cell membrane of untreated cells decreases sharply in cells treated for 48 hours with mevastatin, by a geranyl-geranyl transferase inhibitor (compound of formula (IH)) or by a pure farnesyl transferase inhibitor (compound of formula (I)).
- a geranyl-geranyl transferase inhibitor compound of formula (IH)
- a pure farnesyl transferase inhibitor compound of formula (I)
- table II shows the in vitro values of the proliferative inhibition activities of the compounds of formulas (I) and (II) with respect to human tumor cells MCF-7 not carrying a Ras oncogene which has undergone a mutation. .
- the cells are incubated for 24 hours in the presence of the compounds tested at the doses indicated and then stimulated with 10 8 M of VIP.
- the quantification of cyclic AMP is made by radioimmunoassay.
