(55) A second object of the invention consists of a pharmaceutical composition comprising at least one compound as described above and, optionally, a pharmaceutically acceptable support.

(56) As examples of pharmaceutically acceptable supports, the composition can include emulsions, microemulsions, oil in water emulsions, anhydrous lipids and water in oil emulsions or other types of emulsions.

(57) The inventive composition can further include one or more additives such as diluents, excipients, stabilizers and preservatives. Such additives are well known to those skilled in the art and are described notably in Ullmann's Encyclopedia of Industrial Chemistry, 6.sup.thEd. (various editors, 1989-1998, Marcel Dekker) and in Pharmaceutical Dosage Forms and Drug Delivery Systems (ANSEL et al., 1994, WILLIAMS & WILKINS).

(58) A third object consists of the use of at least one compound as described above in preparing a drug to treat, in a subject, a disease resulting from at least one splicing anomaly.

(59) As used in the present application, the term subject refers to a mammal such as a rodent, cat, dog, primate or human, preferably said subject is a human.

(60) Preferably, the inventive compounds have the ability to inhibit pre-messenger RNA splicing processes that are either constitutive or, more specifically, dependent on regulating sequences known as an ESE (exonic splicing enhancer), ISE (intronic splicing enhancer), ESS (exonic splicing silencer) and ISS (intronic splicing silencer).

(61) In a particularly preferred way, splicing processes are either constitutive and/or or dependent on ESE regulating sequences.

(62) Diseases related to the splicing process include genetic diseases resulting from the alteration of splicing processes, most notably Frasier syndrome, frontotemporal dementia related to chromosome 17 (a form of Parkinson's), Leigh syndrome (a type of encephalopathy), atypical cystic fibrosis, certain neuropathologies including most notably Alzheimer's related to a mutation of the Tau protein, amyotrophy which affects the SMN (survival motor neuron) gene, depression related to dysregulation of serotonin splicing, and certain metastatic cancers in which the overall splicing process is affected (most notably in epithelial cancer including breast cancer, colon cancer, pancreas cancer, liver cancer, prostate cancer, uterus cancer and certain lymphomas).

(63) In a particular embodiment, the use of the at least one compound of the invention is for preparing a drug to treat, in a subject, a cancer, most preferably a metastatic cancer, which cancer is selected in the group comprising breast cancer, colon cancer, pancreas cancer, liver cancer, prostate cancer, uterus cancer.

(64) In light of recent results, it appears that many splicing process anomalies appear with aging.

(65) Additionally, it is thus highly probable that said anomalies play a role in the appearance of pathologies with aging. Examples of diseases that appear with aging and that are likely related to the splicing process include atherosclerosis, insulin resistant type II diabetes, cataracts, osteoporosis and aging of the skin.

(66) Diseases related to the splicing process also include diseases of viral origin for which ESE sequences are identified for splicing. An example of such diseases of viral origin is AIDS.

(67) In another particular embodiment, the use of the at least one compound of the invention is for preparing a drug to treat, in a subject, diseases of viral origin for which ESE sequences are identified for splicing, preferably AIDS.

(68) Other pathologies associated with gene mutations, and which can be treated can exon skipping may also be treated by the compounds of the invention. As an example of such pathologies, one may cite Duchenne muscular dystrophy (DMD).

(69) In still another particular embodiment, the use of the at least one compound of the invention is for preparing a drug to treat, in a subject, diseases associated with gene mutations which may be treated by exon skipping, preferably Duchenne muscular dystrophy (DMD).

(70) Preferentially, the disease related to a splicing anomaly is selected among the group comprising AIDS, cancer, Leigh syndrome characterized by a mitochondrial defect, early-aging syndrome (progeria) and Duchenne muscular dystrophy.

(71) A fourth object of the invention relates to a therapeutic method for treating a subject for a genetic disease resulting from splicing anomalies comprising the administration of a therapeutically effective quantity of a pharmaceutical composition as described above.

(72) A therapeutically effective quantity means a quantity that induces inhibition of the splicing of the pre-mRNAs of interest. Those skilled in the art will be able to determine said therapeutically effective quantity based on their general knowledge and on the methods described in the examples.

(73) The compounds can be administered by any mode of administration such as, for example, by intramuscular, intravenous or oral route, etc.

(74) In one embodiment according to the invention, said composition further includes an excipient making it possible to formulate the inventive compounds in such a way that said composition is provided in solid or liquid form to be prepared and administered by intravenous route.

(75) The inventive compounds preferably will be administered by intravenous route at a concentration of 80-100 mg/m.sup.2. The concentration will be chosen by those skilled in the art according to the organ or tissue to be treated, the state of advancement of the disease and the targeting mode used.

EXAMPLES

(76) The following examples are provided as illustrations and in no way limit the scope of this invention.

Example 1: Development of IDC16 Derivative Compounds

(77) The inventors have shown that compound IDC16 (BAKKOUR et al., cited above, 2007) interacts functionally with the SF2/ASF complex and thus contributes to blocking alternative splicing during HIV replication, leading to the termination of the production of Tat protein.

(78) Accordingly, the family of polycyclic indoles, to which compound IDC16 belongs, is known to exhibit the properties of DNA intercalating agents. Such compounds thus present a risk in terms of undesirable side effects.

(79) The inventors thus sought to develop novel molecules exhibiting activity comparable to IDC16, in terms of activity inhibiting HIV splicing, but while not exhibiting the characteristics of DNA intercalating agents.

(80) In their initial hypothesis, the inventors considered that the two polar heterocycles at the two ends of compound IDC16 were associated with its activity and that the two median rings were of less importance.

(81) Based on this hypothesis, the inventors considered that: the nitrogen of the indoline and of the D ring of IDC16 might act as acceptors of hydrogen bonds; the N-methylated 4-pyridinone motif might be preserved in the analogues; the flat tetracyclic geometry was not optimal and it might be wise to replace the B and C rings by other motifs to limit DNA intercalating properties.

(84) Synthesis of the compounds described in table I is described below.

(85) Synthesis of Stilbene (Olefin) Compounds

(86) ##STR00214##

(87) 4-Chloropyridine 1 is obtained by neutralization of 4-chloropyridine hydrochloride with 10% NaOH as described in SCHMID & WOLKOFF (Canadian Journal of Chemistry, vol. 50, p. 1181-1187, 1972). 4-Chloropyridine 1 (15 mmol) is reacted in THF (250 ml) at 78 C. (nitrogen atmosphere) with 1.2 equivalents of lithium diisopropylamide (1.5 M solution in hexanes containing one equivalent of THF, ALDRICH) (THRASHER et al., Heterocycles, vol. 67, p. 543-547, 2006).

(88) Reaction of the resulting anion with either an excess of anhydrous DMF or an excess of methyl formate allows the formation of 4-chloropyridine-3-carboxaldehyde 2, isolated in the form of a colorless solid (60-70%).

(89) Following the procedure described in MARSAIS et al. (J. Het. Chem., vol. 25, p. 81-87, 1988), compound 2 is heated for 6 h in an aqueous solution of 3 N HCl containing several drops of 3% H.sub.2O.sub.2, in order to obtain 4-hydroxypyridine-3-carboxaldehyde 4 as a colorless solid (>80%).

(90) Following the procedure described in DI MARCO (Eur. J. Inorg. Chem., p. 1284-1293, 2006), pyridine aldehyde 4 is reacted with an excess of methyl iodide for 2 h in DMF at 100 C. in order to obtain compound 6 isolated in the form of a colorless solid.

(91) NMR and mass spectra data for compounds 2, 4 and 6 correspond to values found in the literature.

(92) Finally, compound 6 serves as a skeleton for the synthesis of stilbene analogues of IDC16, notably compounds 8a-j. This reaction involves placing compound 6, under the classic conditions of the WITTIG reaction (see for example GOPALSAMY et al., J. Med. Chem., vol. 47, p. 1893-1899, 2004), in contact with the required phosphonium salts obtained either commercially or prepared by reacting the required bromide derivative with triphenylphosphine. For all of the compounds 8a-j, the presence of E double bond geometry is deduced from the values of the 400 MHz 1H NMR spectrum.

(93) Synthesis of Amide Compounds

(94) As above, 4-chloropyridine 1 is obtained by neutralization of 4-chloropyridine hydrochloride with 10% NaOH as described in SCHMID & WOLKOFF (Canadian Journal of Chemistry, vol. 50, p. 1181-1187, 1972). 4-Chloropyridine 1 (15 mmol) is reacted in THF (250 ml) at 78 C. (nitrogen atmosphere) with 1.2 equivalents of lithium diisopropylamide (1.5 M solution in hexanes containing one equivalent of THF, ALDRICH) (THRASHER et al., Heterocycles, vol. 67, p. 543-547, 2006).

(95) Reaction of the resulting anion with dry CO.sub.2 allows the formation of 4-chloropyridine-3-carboxylic acid 3 (4-chloronicotinic acid), isolated as a colorless solid with a yield of 60-80% (see GUILLIER et al., J. Org. Chem., vol. 60, p. 292-296, 1995).

(96) Compound 3 is heated in water (see ROSS, J. Chem. Soc. (C), p. 1816-1821, 1966) to obtain 4-hydroxypyridine-3-carboxylic acid 5 as a colorless solid (>80%).

(97) Acid 5 is reacted in the presence of an excess of methyl iodide in DMF at 1000 C. for 2 h. Compound 7 is then isolated as a colorless solid.

(98) NMR and mass spectra data for compounds 3, 5 and 7 correspond to values found in the literature.

(99) Finally, compound 7 serves as a skeleton for the synthesis of amide analogues of IDC16, notably compounds 9a-j. This reaction involves placing compound 7 in contact with the required aromatic and heteroaromatic amines under classical conditions for forming peptide bonds. Typically, compound 7 in solution in DMF containing N-methylmorpholine is reacted with isobutyl chloroformate (0 C. or room temperature, 1 hour), and compounds 9a-j are then isolated as colorless solids with yields of 60-90%. These compounds are finally characterized by mass spectroscopy and 1H NMR (400 MHz).

(102) 4-Chloropyridine-3-carboxylic acid 3 is reacted under classical peptide coupling conditions with isobutylchloroformate (1.3 equivalents) and N-methyl morpholine (1.3 equivalents) in DMF at room temperature and the active ester intermediate is then treated with a solution of anhydrous hydrazine (1 equivalent; 1.0 M solution in THF; ALDRICH) stirred constantly overnight (Intl. J. Pepetide & Protein Res., vol. 11, p. 297, 1978). The mixture containing hydrazide 10 is then filtered to eliminate solids and heated at 100 C. for 2-4 hours to form a ring and to obtain compound 11.

(103) Compound 11 is reacted in the presence of an excess of methyl iodide in DMF at 1000 C. for 2 h. Compound 12 is then isolated as a colorless solid.

(104) Compound 12 is alkylated to obtain compounds 13a-j and 14a-j according to techniques well known to those skilled in the art (see in particular STARKOV, Tet. Letters, vol. 48, p. 1155-1157, 2007).

(106) ##STR00216##

(107) 4-Hydroxy-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate 15 is prepared according to the protocol described in WALLACE et al. (J. Med. Chem., vol. 49, p. 441-444, 2006), then reacted with potassium trimethylsilanolate in THF for 4-5 hours at 20 C. (MOTORINA et al., J. Am. Chem. Soc., vol. 23, p. 8-17, 2001), and the corresponding potassium salt 16 of the acid obtained after vacuum concentration is resuspended in DMF and reacted with isobutyl chloroformate and N-methyl morpholine (2 eq.) at room temperature, and then hydroxylamine in MeOH is added to the mixture (REDDY, Tet. Letters, vol. 41, p. 6285-6288, 2000). Hydroxamic acid intermediate derivative 17 is then resuspended in CH.sub.2Cl.sub.2 containing isopropylethylamine and treated with mesyl chloride (1 eq.) and stirred at room temperature for 24 h. The desired product with a closed ring 18 is produced by allowing the reaction to proceed, and then the solvent is eliminated by vacuum drying.

(108) Compound 18 is alkylated to obtain compounds 19a-j and 20a-j again according to techniques well known to those skilled in the art (see notably STARKOV, Tet. Letters, vol. 48, p. 1155-1157, 2007).

(111) Numerous compounds of formula 22 are already well known (approximately 1,500 compounds identified in SciFinder). Said compounds can be simply obtained from 3,4-daminopyridine.

Example 3: Selective Inhibition of HIV-1 mRNA Splicing Ex Vivo by Compounds According to the Present Invention

(112) The efficiency of the compounds described in example 2 was tested using pPSP plasmid (JACQUENET et al., J. Biol. Chem., vol. 276, p. 40464-40475, 2001), which contains the proviral HIV-1 genome with a deletion of nucleotides 1511 to 4550. This pPSP plasmid contains all HIV-1 splicing sites and the relative use of these various sites appears similar to that of the wild virus.

(113) HeLa cells were cultivated in RPMI 1640 medium (GIBCO) supplemented with fetal calf serum on plates 3 cm in diameter (NUNC) to a confluence of 70-80%. These cells were then transfected with the pPSP plasmid as described in JACQUENET et al. (2001).

(114) The HeLa cells transfected with pPSP were then treated with various concentrations (1.5 M or 3 M) of the compounds described in example 2 or of IDC16 as a positive control. As a negative control, cells transfected with pPSP, but without subsequent treatment, were included (Clt).

(115) Total cellular RNA was then extracted with the RNeasy kit (QIAGEN) while following the manufacturer's instructions. 4 g of total RNA then underwent reverse transcription using the OMNISCRIPT REVERSE TRANSCRIPTASE kit (QIAGEN) while following the manufacturer's instructions. The mixture obtained was then aliquotted in 96-well plates and subjected to amplification using BSS sense primers (5-GGCTTGCTGAAGCGCGCACGGCAAGAGG-3; SEQ ID NO: 1), SJ4.7A anti-sense primers (5-TTGGGAGGTGGGTTGCTTTGATAGAG-3; SEQ ID NO: 2) and primers to amplify GAPDH as an internal control. BSS and SJ4.7A primers make it possible to amplify several isoforms resulting from various splices coding for viral proteins Nef, Rev, and Tat (JACQUENET et al., cited above, 2001). The PCR products were then analyzed by polyacrylamide gel electrophoresis after standardization with GAPDH (SORET et al., Proc. Natl. Acad. Sci. U.S.A., vol. 102, p. 8764-8769, 2005).

(116) FIG. 1 shows the detail of a polyacrylamide gel obtained presenting the various isoforms obtained (Nef2, Rev1, Rev2, Nef3, Nef4, Nef5, Tat1 and Tat2) for the untreated cells (Clt) or treated with the compounds IDC16, C48, C49, C55 or C56.

(117) The results show a dose-dependent reduction in the level of HIV-1 splicing products for the cells treated with compounds C48, C49, C55 and C56, a reduction comparable to that obtained in the presence of compound IDC16.

(118) Consequently, the results thus show that compounds C48, C49, C55 and C56 inhibit HIV-1 splicing with an efficiency comparable to compound IDC16.

Example 4: Inhibition of HIV-1 Production in Infected Peripheral Blood Mononuclear Cells (PBMCs)

(119) The first determination is that of the concentration of compound that exhibits the fewest side effects in terms of cell viability and progression of the cell cycle.

(120) Within this framework, the peripheral blood mononuclear cells (PBMCs) of healthy donors are isolated by centrifugation on a FICOLL gradient. The cells are then cultivated to a density of 2.510.sup.6 cells/ml with RPMI medium supplemented with 1% inactivated human AB serum, then incubated at 37 C., 5% CO.sub.2 for an additional hour. The peripheral blood mononuclear cells are then recovered and cultivated for two days in RPMI medium supplemented with 10% fetal calf serum.

(121) Part of the peripheral blood mononuclear cells (PBMC) is then cultivated for 72 hours in the presence of tritiated thymidine and phytohemagglutinin A (PHA) and in the presence or absence of the compounds described in example 2. Cell proliferation in the presence of the compounds of example 2 is finally measured by determining the incorporation of tritiated thymidine in the cellular DNA of the treated cells.

(122) Another part of the peripheral blood mononuclear cells (PBMCs) that is activated (stimulated for 2 days with PHA and IL-2) is infected with HIV strains NL4.3 or Ada-M R5. The cells are then cultivated for 14 days in the presence of the compounds described in example 2. Viral replication is finally determined by quantifying protein p24 by the ELISA method. In parallel, cell viability is measured by exclusion with trypan blue in comparison with that of the untreated cells.

Example 5: Inhibition of HIV-1 Production in Infected Macrophages

(123) In order to generalize the HIV-1 replication effect of the molecules described in example 2 to other cell types, we examined various steps of the viral cycle in cells treated with the various drug at a concentration of 5 M and submitted to one-round infection.

(124) For such experiences, macrophages can be infected by the Ada-M R5 HIV strain and treated for 18 hours with various concentrations of the compounds described in example 2. The culture medium is then eliminated and the cells washed with an abundance of PBS. The cells are then cultivated under normal conditions. The culture medium and the cells are then collected at days 4, 7 and 14. Finally, virus replication is measured indirectly by determining the level of p24 antigen in both the culture supernatant and the cellular lysate by the ELISA method. In parallel, cell viability of the macrophages in the presence of the compounds of example 2 is measured as before.

(125) For this purpose, we exposed HOS-CD4.sup.+-CCR5.sup.+ cells to defective virions obtained by cotransfecting 293T cells with a plasmid encoding the R5 envelope of the AD8 strain and another plasmid containing the entire HIV-1 genome mutated in the envelope gene and harbouring a luciferase marker gene fused to nef (Connor R I, Chen B K, Choe S, Landau N R. (1995) Vpr is required for efficient replication of human immunodeficiency virus type-1 in mononuclear phagocytes. Virology 206: 935-944). The amounts of luciferase activity in cells infected with these virions reflect both the number of integrated proviruses and expression of multiply spliced species encoding nef/luc. Two days post-infection, luciferase activity in HOS-CD4+-CCR5+ infected cells was measured. Of note, the inhibitory effect could be smaller in this one-round infection assay than in other assays where several rounds of infection were carried out. Among the compounds of the example 2 tested, 12 show a luciferase inhibitory effect ranging between 30% up to 52%, which compound are listed in table II.

(127) Only compounds that demonstrated less than 10% toxicity are shown. The results established that compared to Azidothymidine (AZT, 3-azido-3-deoxythymidine, zidovudine) which is the first nucleoside reverse transcriptase inhibitor (NRTI) approved for HIV-1 therapy, our compounds are 10 times more efficient than AZT. In fact, a concentration of 50 M of AZT is required to achieve 32% inhibition of luciferase under the same conditions.

Example 6: Absence of Inhibition of Splicing of Cellular Genes

(128) In order to identify the effect of the compounds of example 2 on the splicing of endogenous genes, 96 isoforms obtained after alternative splicing and covering a variety of apoptotic genes were selected.

(129) Peripheral blood mononuclear cells are treated or not treated with the compounds of example 2 and IDC16 as a positive control as described in example 3. Preparation of total RNA for each culture condition followed by preparation of cDNA for each RNA sample is then carried out as described in example 3.

(130) The mixture obtained is then aliquotted in 96-well plates and subjected to amplification using for each well a pair of sense and anti-sense primers specific to each isoform.

(131) The level of expression of each isoform for the cells treated with the compounds of example 2 is then compared with that obtained for the cells treated with IDC16 and for the untreated cells.

Example 7: Identification of Effective Compounds to Treat Metastatic Breast Cancers

(132) By alternative splicing the RON proto-oncogene generates two protein isoforms with distinct properties: 1) RON is a tyrosine kinase receptor involved in tissue dissociation, cell mobility and invasion of the extracellular matrix, 2) the truncated isoform of the RON receptor is constitutively active due to the elimination of exon 11 sequences. This truncated isoform is expressed strongly in breast cancer cells with high metastatic capacity and its expression is sufficient to activate epithelial-mesenchymal transition.

(133) To test the effectiveness of the compounds described above in treating metastatic breast cancer, cells preferentially expressing the truncated RON isoform were treated with various concentrations of the compounds described in example 2. The effectiveness of said compounds is then measured by determining the level of expression of the truncated RON isoform in the treated or untreated cells, with effective compounds corresponding to those that lower the level of expression of said isoform.

(134) Other protocols are available for testing the effectiveness of the compounds described above in treating metastatic cancer. One of these protocols corresponds to the wound Healing assay protocol testing cell migration.

(135) To mimics cell migration during wound healing in vivo, we have used the wound-healing assay to study directional cell migration in vitro (Rodriquer et al., Methods Mol Biol, 2005). A cell monolayer of seed Breast cancer cells (MDA-MB231 Luc D3H2LN) is treated with 5 M of indicated molecules for 48 h before a wound is created, images were then captured at the beginning and at regular intervals during cell migration to close the wound. Images were compared to control untreated cells or to compounds that have no effect on cell migration. Wounds can heal in as little as 12-24 hours for highly metastatic cells, or may take up to 72 hours for less metastatic cells. Images of the same field at 0, 2, 4, 6, 8, 10, 12, 18 and 24 hours until the closure of the entire wound using phase-contrast light microscopy (10 magnifications).

(136) The FIG. 2 shows that the compounds MB260, FMB008 and FMMB22.3 strongly inhibit cell migration compared to negative control (CTL).

Example 8: Identification of Effective Compounds for Treating Duchenne Muscular Dystrophy

(137) As target for gene therapy, Duchenne muscular dystrophy (DMD) presents many obstacles but also unparalleled prospect for correction by alternative splicing. Duchenne muscular dystrophy results from mutations in the dystrophin gene, leading to the absence of its expression or to the expression of truncated proteins. More specifically, the majority of mutations in the dystrophin gene occur in the region encoding the spectrin-like central rod domain (see dia 1), which is largely dispensable. Exon 51 is one of the most mutated exon of encoding the spectrin-like central rod domain in DMD patients. The skipping of exon 51 can generate a shortened but in-frame transcript, permitting translation of a partially functional dystrophin protein.

(138) To test the inventive compounds, an animal model of Duchenne muscular dystrophy can be used, namely the mdx mouse. More specifically, mdx mice carry a stop codon mutation in exon 23 of the dystrophin gene which is responsible for completely extinguishing dystrophin expression. Thus, mdx mice can be treated with various concentrations of the compounds described in example 2 and then myoblast samples are taken from these mice to test these compounds for their capacity to induce exon 23 skipping in these cells.

(139) Presently, we have tested this idea using stable cell lines expressing a luciferase reporter in which exon 51 and flanking introns were inserted in the middle of the luciferase cDNA. Because exon 51 was constitutively included between luciferase halves no luciferase activity was detected in these stable cell lines. In contrast in the presence of AAV vectors harbouring U7 antisens designed to promote skipping of exon 51, luciferase activity was restored. We have used this system to screen molecules able to potentiate the efficacy of AAV vectors. The compounds of example 2 have been tested (5 m) in this system and the results for the most efficient molecules are disclosed in Table III.

(140) TABLE-US-00003 TABLE III % of Compound Activity (5 m) Structure Compound luciferase* FMMB21.1 0 2-(2-Dimethylamino- ethylamino)-N-(4- methoxy-phenyl)- nicotinamide 220 FMMB22.1 2-(2-Dimethylamino- ethylamino)-N-(4- methoxy-phenyl)- benzamide 220 FMB080 2-Chloro-N-(3- methoxy-phenyl)- nicotinamide 150 MB228 4-(5-Chloro-1H- imidazol-2-yl)-2- methyl-phenyl]- (4-methoxy-phenyl)- amine 180 MB260 2-Chloro-N-(4- methoxy-phenyl)- nicotinamide 200 MB261 2-Bromo-N-(4- methoxy-phenyl)- benzamide 220 MB262 2-Bromo-N-(3- methoxy-phenyl)- benzamide 180 *luciferase activity reflect exon skipping induced by 5000 MOI of AAV vector harbouring an anti-sense sequence of exon 51 of Dystrophin gene

(141) Among the compounds of example 2 tested 7 showed a two fold increase of luciferase activity compared to AAV vector alone. These molecules are, therefore, potent therapeutic agent for DMD treatment.

Example 9: Identification of Effective Compounds for Treating Early-Aging Syndrome (Progeria)

(142) Progeria is a rare (prevalence of approximately one in four to eight million births) and very severe developmental disorder characterized by the early appearance of certain pathologies usually developed during physiological aging, such as atherosclerosis, insulin resistant type II diabetes, cataracts, osteoporosis and aging of the skin. Analysis of this pathology has shown that it results from abnormal expression of the LMNA gene associated with its abnormal splicing. Astonishingly, this same aberrant splicing of the LMNA gene has been found in healthy elderly subjects not carrying the mutation.

(143) It could be shown that certain compounds acting on splicing are able to increase the use of the normal LMNA gene splicing site while that of the aberrant splicing site decreases. To test the effectiveness of the compounds described in example 2 in treating progeria, cells carrying a mutation of the LMNA gene causing its abnormal splicing were treated or not treated with various concentrations of said compounds. The effectiveness of said compounds is then measured by determining the level of expression of the abnormal isoform in the treated or untreated cells, with the effective compounds corresponding to those that lower the level of expression of said isoform.
