The present invention concerns new inhibitors of LIMK and/or ROCK kinases, and therapeutic uses thereof. The present invention also concerns these new inhibitors as anticancer agents.
LIM kinases (LIMKs) are serine/threonine and tyrosine kinases involved in regulating cytoskeleton dynamics. They phosphorylate cofilin, resulting in its inhibition (Scott, R. W. and Olson, M. F. (2007) LIM kinases: function, regulation and association with human disease. Journal of molecular medicine (Berlin, Germany). 85, 555-568). Cofilin is a member of the Actin Depolymerizing Factor (ADF) family and regulates actin polymerization dynamics by promoting rapid turnover of actin filaments (Bamburg, J. R. and Bernstein, B. W. (2010) Roles of ADF/cofilin in actin polymerization and beyond. F1000 biology reports. 2, 62; Mizuno, K. (2013) Signaling mechanisms and functional roles of cofilin phosphorylation and dephosphorylation. Cellular signalling. 25, 457-469; Pollard, T. D. and Borisy, G. G. (2003) Cellular motility driven by assembly and disassembly of actin filaments. Cell. 112, 453-465). LIMKs also control microtubule dynamics, independently from their regulation of actin remodeling. The molecular mechanism by which LIMKs regulate microtubule dynamics is still unknown (Prunier, C., Prudent, R., Kapur, R., Sadoul, K. and Lafanechere, L. (2017) LIM kinases: cofilin and beyond. Oncotarget. 8, 41749-41763). LIMKs thus play a crucial role in cytoskeleton remodeling, contributing to many cellular functions, such as cell motility, morphogenesis, division, differentiation, apoptosis, neuronal morphology, neuritogenesis, and oncogenesis.
The LIMK family consists of only two members: LIMK1 and LIMK2. Recently, LIMKs have emerged as new therapeutic targets as they have been shown to be involved in many diseases, for example in numerous cancers, in viral infection, in ocular hypertension and glaucoma formation. They also play a role in Neurofibromatosis type 1 and 2 (NF1 and NF2). LIMKs are also involved in psoriatic lesions, in the inflammatory response, in the development of inflammatory hyperalgesia, central sensitization and chronic pain, in oocyte maturation, and in erectile dysfunction due to old age. More recently, LIMKs have been shown to play key roles in neuronal development and plasticity, they are involved in several neuronal diseases such as Amyotrophic Lateral Sclerosis, Parkinson and Alzheimer diseases, Williams-Beuren syndrome, schizophrenia, intellectual deficiency, … Rho-associated coiled-coil-containing kinases (ROCKs) are serine/threonine kinases, members of the AGC kinase family (Hartmann, S.; Ridley, A.J.; Lutz, S. The Function of Rho-Associated Kinases ROCK1 and ROCK2 in the Pathogenesis of Cardiovascular Disease. Front. Pharmacol.2015, 6, 276). ROCKs phosphorylate several targets : 1/Myosin Light Chain (MLC) together with Myosin Light chain Phosphatase (MLCP) thereby inactivating this later and allowing MLC phosphorylation to persist (Amano, M.; Nakayama, M.; Kaibuchi, K. Rho- kinase/ROCK: A key regulator of the cytoskeleton and cell polarity. Cytoskeleton 2010, 67, 545–554). This results in actomyosin contractility stimulation and cellular contraction.2/ LIMK2 which becomes activated and phosphorylates cofilin leading to the inactivation of this latter and actin filament stabilisation (Maekawa, M.; Ishizaki, T.; Boku, S.;Watanabe, N.; Fujita, A.; Iwamatsu, A.; Obinata, T.; Ohashi, K.; Mizuno, K.; Narumiya, S. Signaling from Rho to the actin cytoskeleton through protein kinases ROCK and LIM-kinase. Science 1999, 285, 895–898). 3/ Ezrin, radixin and moesin (ERM), which are involved in actin/plasma membrane interactions (Matsui, T.; Maeda, M.; Doi, Y.; Yonemura, S.; Amano, M.; Kaibuchi, K.; Tsukita, S.; Tsukita, S. Rho-kinase phosphorylates COOH-terminal threonines of ezrin/radixin/moesin (ERM) proteins and regulates their head-to-tail association. J. Cell Biol. 1998, 140, 647–657).4/ Collapsin response mediator protein-2 (CRMP-2), thereby inhibiting its ability to stimulate microtubule assembly and axonal growth (Arimura, N.; Menager, C.; Fukata, Y.; Kaibuchi, K. Role of CRMP-2 in neuronal polarity. J. Neurobiol.2004, 58, 34–47). 5/ PTEN (phosphatase and tensin homolog), a tumor suppressor thereby preventing it to inhibit cell growth and survival (Li, Z.; Dong, X.;Wang, Z.; Liu,W.; Deng, N.; Ding, Y.; Tang, L.; Hla, T.; Zeng, R.; Li, L.; et al. Regulation of PTEN by Rho small GTPases. Nat. Cell Biol.2005, 7, 399–404). Collectively, these actions play a role in actin cytoskeleton remodelling, cell contractility and cell death. Accordingly, ROCKs regulate different cellular functions such as growth, apoptosis, migration and metabolism. ROCKs are involved in different pathologies: cardiac diseases such as cardiac fibrosis, cardiac hypertrophy, systemic blood pressure disorders, pulmonary hypertension, renal pathologies such as hypertensive nephropathy, Bartter and Gitelman syndrome, diabetic nephropathy, asthma, chronic obstructive pulmonary diseases, traumatic brain injuries, Alzheimer and Parkinson diseases, obesity, diabetis mellitus, cancers, autoimmune diseases (Lupus erythematosus, rhumatoid arthritis). The aim of the present invention is to provide new small molecules with an inhibition activity against LIMK and/or ROCK kinases. The aim of the present invention is to provide new inhibitors of LIMK and/or ROCK kinases. Another aim of the present invention is to provide new inhibitors of LIMK and ROCK kinases. Another aim of the present invention is to provide new potent inhibitors targeting both LIMKs and ROCKs or specific of LIMKs according to the targeted disease. Another aim of the present invention is to provide new small molecules as inhibitors of LIMK and/or ROCK kinases, said molecules having a wide range of cytotoxicity, from low toxicity to high toxicity according to the potent applications.

Inhibition of LIMK1 and LIMK2 Inhibition of LIMK1 and LIMK2 was measured with « Lanthascreen ^ Eu binding assay » (Life Technologies). This TR-FRET assay is based on the competition between a fluorescent tracer and the inhibitor to be tested, allowing the determination of an inhibition constant, Ki. 133 compounds have been tested. A dozen of these compounds have their Ki below 10 nM, and about fifty below 50 nM. These results are very promising, as Ki values of the reference compounds LIMKi3 and LX7101 are 8 and 3.9 nM, respectively, and the Pyr1 compound tested on breast cancer tumors has an IC 50 of 50 nM on LIMK1 and 75 nM on LIMK2. 1.2. Inhibition of ROCK1 and ROCK2 ROCK1 and ROCK2 inhibition has also been assessed, but at a single concentration of 1 ^M. These tests have been performed by using the « Z’Lyte ^ » assay based on the inhibition of the phosphorylation of a reference measured by FRET (Life Technologies). Based on this assay, the compounds were classified in two groups: (i) compounds selectively inhibiting LIMKs, (ii) potential “dual” compounds inhibiting both LIMKs and ROCKs. 1.3. Selectivity on a panel of 100 kinases The selectivity of the compounds towards LIMK1 and LIMK2 has been tested by Eurofins Kinase Screening & Profiling Services against 100 representative kinases at the concentration of 1 µM. 18 compounds have been tested. 6 of them are highly selective and inhibit exclusively LIMK1 and LIMK2 at more than 80%. These compounds are good candidates for future in vivo assays. Selective compounds avoid off-targets and secondary effects that might be deleterious. Especially, we want to develop compounds that do not target ROCK1 and ROCK2 the kinase upstream of LIMK1/2 that has many physiological targets. LIMK1 and LIMK2 are really downstream of their signalling pathway, the only downstream effector is their quasi-unique substrate cofiline. By targeting selectively LIMK1 and LIMK2, we should avoid side effects. 2. In cell assays Six in cell assays have been used to characterize the activity of our compounds: 1. Determination of cytotoxicity on several cell lines 2. Actin cytoskeleton remodelling, by measuring the level of phospho-cofilin, cofilin is the canonical substrate of LIMKs; 3. Actin cytoskeleton dynamics, by visualising stress fibers induced by LIMK2 overexpression 4. Migration properties measured by a wound-healing assay 5. Microtubule dynamics by visualizing mitotic spindles 6. Dendrite plasticity by measuring their size 2.1. Cytotoxicity The cytotoxicity of our compounds was assessed with the « CellTiter-Glo ^ Luminescent Cell Viability » assay from Promega. This assay is based on the production of ATP by live cells. Two cell lines were studied; HeLa, and MPNST (Malignant Peripheral Nerve Sheath tumor, tumors associated with Neurofibromatose type I genetic disease). Day 1: Cell preparation in 96 well plates Seed HeLa cells at 10,000 cells per well in 100 µl of DMEM. Seed MPNST cells at 30,000 cells per well in 100 µl of DMEM. Day 2: Incubation with the inhibitor For each inhibitor, a 1 mM solution in DMEM is prepared from the 10 mM stock solution. Serial dilutions are made from this solution with DMEM, to reach the following concentrations: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 µM. Cell medium is removed, and 100 µL of the solution of the inhibitors at the different concentrations are added. Control conditions: (i) 100µl of 1 :100 DMSO, (ii) 100 µL of DMEM. Incubation for 48 hours at 37 °C under CO2 and humid atmosphere. Day 4: Cytotoxicity determination with the "CellTiter-Glo ^ Luminescent Cell Viability” assay from Promega, readout of the plates with Mithras apparatus. The plate is removed from the incubator. 100 µL of reagent is added to each well. The plate is then incubated at 22 °C for 30 minutes. A standard with ATP diluted in DMEM is prepared: 100 µL of 1µM, 100 nM and 10 nM in triplicate to load on the same plate. Readout luminescence on Mithras apparatus. Data interpretation. Luminescent values are directly linked to the amount of ATP present in the cells, this amount of ATP is linked to the number of live cells. Data are normalized, 100% corresponds to the control condition 1:100 DMSO. 50 compounds have been tested on HeLa cell lines. EC50 (inhibitor concentration corresponding to half of live cells) of most of the compounds of the invention are between 15 and 35 ^M as compared to those of LIMKi3 and Pyr1 on HeLa cells which is 9 and 1 µM, respectively. 17 compounds have been tested on MPNST cell line. EC50 of the compounds of the invention are between 35 and 90 ^M (Table 1). Compared to published data, T56-LIMKi, the compound developed by Y. Kloog, has an EC 50 of about 20 ^M on the MPNST cell line. Table 1: Cytotoxic effect of the library on 9 representative cell lines. 2.2. Actin cytoskeleton remodelling by measuring the level of phospho- cofilin Cofilin is the canonical substrate of LIMKs. LIMKs inhibit cofilin by phosphorylation of its Serine 3. As cofilin is an Actin Depolymerization Factor (ADF), its inactivation blocks actin cytoskeleton remodelling. The effect of the compounds on the level of phosphorylation of cofilin was measured by Western Blot, using a specific antibody: anti-phospho-Ser3-cofilin. HeLa and MPNST cell lines were studied. Day 1: Cell preparation in 6 well plates Seed HeLa cells at 150,000 cells per well in 2 mL of DMEM. Seed MPNST cells at 500,000 cells per well in 2 mL of DMEM. Day 3: Incubation with the inhibitor and lysis 5 µl of the 10 mM stock solution or 5 µL of DMSO (control) are added to the media of the cultured cells => final concentration: 25 µM. Incubate for 2 hours at 37 °C under CO2 and humid atmosphere. Lysis: Remove the media. Wash the cells twice with 1 ml PBS, and incubate with 150 µl of lysis buffer (50 mM Tris/HCl, pH 7.5, 100 mM NaCl, 5 mM EDTA, 0.1% Triton X-100, 50 mM NaF, 10 mM sodium pyrophosphate, 1 mM Na3VO4,20 mM p- nitrophenyl phosphate, 20 mM ^-glycerophosphate, 10 mg/mL aprotinin, 0.05 mg/mL okaidic acid, 1 mg/mL leupeptin, 1 mM PMSF) for 10 minutes on ice. Cell are collected (with a cell scraper), transferred in a tube and centrifuged at 10,000xg for 10 minutes at 4°C. Take 60 µL of supernatant and add 20 µL of Laemmli buffer 4x. Heat the samples at 95 °C for 5 minutes, spin at 10,000xg for 5 minutes, and analyse by Western Blot. Antibodies are anti-phosphoSer3-cofilin (#3313) and anti- cofilin (#3312) from Cell Signalling Technology (Figure 1 - Example of a Western Blot after treatment of HeLa cells with several inhibitors. Antibodies used in this experiment: upper part anti-phospho-Ser3-cofilin, lower part anti-cofilin). The control condition correspond to cells incubated with DMSO (solvent in which inhibitors are diluted). The rate of phospho-cofilin is quantified, divided by the rate of total cofilin, and normalized with the control condition DMSO (100% of phosphorylation). Each sample is analyzed twice to increase reproducibility, and the best molecules are tested twice in two independent experiments. M) , 31 92,3 LX7101 85,1 110 79 15 92,1 135 85 133 78,8 Table 2: % of inhibition of cofilin phosphorylation (normalized to the control condition DMSO). 70 compounds have been tested on HeLa cell line. More than 80% of inhibition of the phosphorylation of the cofilin is observed. 50 compounds are more efficient than LIMKi3, 24 of these compounds are more efficient than LX7101. 20 compounds have been tested on MPNST cell line. Cofilin phosphorylation is inhibited between 60 and 80%. 9 compounds are more efficient than LIMKi3 and LX7101. Furthermore, 3 compounds which are not very good on the HeLa cell line (60 % of inhibition of phospho-cofilin) are really efficient on the MPNST cell line (80 % of inhibition of phospho-cofilin). These data suggest that some compounds selectively inhibit specific cell lines, and so they may target specific diseases. To conclude, the compounds of the invention are highly active in cell on the direct phosphorylation of cofilin by LIMKs. Cofilin phosphorylation was also tested by using another technic: LUMIT ^ technology from Promega. LUMIT ^ technology is an immunoassay based on luminescence detection. It requires the use of two different secondary antibodies coupled to a small and a big subunit of nanoluciferase respectively. When the two antibodies are fixed on their analyte, full nanoluciferase is reconstituted and active, it generates a bright luminescent signal in presence of its substrate. We have set up the optimale conditions to measure phospho-cofilin with this assay. And we are now testing the compounds of the invention with this new technic to reinforce our results obtained by western-blot. 2.3. Actin cytoskeleton dynamics by visualising stress fibers induced by LIMK2 overexpression Another approach was then developed to test the efficiency of the compounds of the invention directly in live cells by imaging. In HeLa cells, stress fibers induced by LIMK2 overexpression are visualized by immunofluorescence. Indeed, when LIMK2 is overproduced, it phosphorylates cofilin, resulting in its inhibition. Cofilin can no longer depolymerise actin filaments, stress fibers are then observed. Day 1: Cell preparation in 6 well plates Seed HeLa cells at 30,000 cells per well in 2 mL of DMEM. Day 2: Transfection Remove the media from the cells. Add 1.5 mL of DMEM. In Eppendorf tubes, add 150µL of OptiMEM. Dilute 2.5 µg of DNA (Plasmidic preparation) in 150 µL of OptiMEM. Mix the + Reagent (Invitrogen), add 7.5 µL of + Reagent to the previous mixture. Homogenize by inversion. Incubate 5min at room temperature. Mix Lipofectamin LTX (Invitrogen). Add 7.5 µL of Lipofectamin LTX to 150 µL of OptiMEM in a new tube. Homogenize by inversion. Incubate 5 min at RT. Add the OptiMEM-ADN mix to the OptiMEM-Lipofectamin mix. Homogenize by inversion. Incubate 30 min at RT. Add on the top of the cells the OptiMEM-ADN-Lipofectamine mix without agitating to prevent complex disruption, drop by drop everywhere in the well. Incubate for 4 to 5 hours. Change the media. Day 3: Seed the cells in 4 well plates Treat the cells with trypsin to detach them from the plate. Seed cells at 20,000 cellules per wells in 500µl of DMEM. Day 4: Incubation with the inhibitors and labelling Cells are incubated for 2 hours with 25 µM of inhibitors (i.e.1.25 µl of 10 mM stock solution) or 1.25 µL of DMSO (control) at 37°C under CO2 and humid atmosphere. Labelling: Remove the media. Wash three times with 500 µL of PBS 1x. Add 250 µL of PBS/4% PFA. Incubate 20 min at RT. Remove PBS/PFA. Wash 3 times with 500 µL of PBS 1x. Add 250µL of PBS/0.5% Triton. Incubate 15 min at RT. Remove PBS/Triton. Wash 3 times with 500 µL of PBS 1x. Add 250 µL of primary antibody (anti-HA from Roche Applied Science) diluted in PBS/1% BSA. Incubate 1h at RT. Remove primary antibody. Wash 3 times with 500 µL of PBS/0.5% BSA. Add 250 µL of secondary antibody (FITC anti-rat) or 250 µL de phalloidin coupled to AlexaFluor568 diluted in PBS/1% BSA. Incubate 1h at RT with no light. Remove the media. Wash 3 times with 500 µL of PBS/0.5% BSA. Mounting Mount coverslip with a drop of Vectashield (5µL). Seal coverslip with nail polish to prevent drying and movement under microscope. Store in dark at - +4 °C for 2-3 days, and then at -20 °C. LIMK2 overexpression does induce stress fiber formation, which are not sensitive to DMSO treatment. When cells are treated with our compounds, stress fibers are much less numerous (Figure 2 - Confocal imaging of actin cytoskeleton. HeLa cells are transfected with a plasmid allowing the overproduction of LIMK2, treated for 2 h with 25 µM of inhibitors or DMSO (control). Stress fibers are visualized by phalloidin labelling, which binds to filamentous actin, by immunofluorescence (stress fibers appear as white thick lines inside the cells)). Therefore, the compounds of the invention inhibit stress fiber formation induced by LIMK2 overexpression. This second test further shows that our compounds are efficient on the dynamics of actin filament polymerisation in live cells. 2.4. Migration properties measured by a wound-healing assay Effects of the compounds of the invention on cell migration were measured by a wound-healing assay. A scratch was made on a cell monolayer, and the speed of cells to migrate to close the gap was measured. U2OS cells were inoculated at the density of 40000 by well (96 well plate), grown overnight. 5 h before wound-healing, cells were starved in 0.5% fetal calf serum. Wound-healing was performed by a WoundMaker™ (Essen BioScience). Inhibitors were added in the medium at a final concentration of 2.5 µM. Data are acquired and analysed every hours during 24h by an IncuCyte® S3 (Sartorius, Essen BioScience, MI UA). The results are shown in Figure 3.8 compounds have been tested.4 of them have stronger propensity to inhibit U2OS cell migration upon scratch compared to the reference LIMKi3. 1 compound is particularly efficient (compound 15). These data show that the tested compounds are efficient on cells to prevent their migration, a property playing a major role in the formation of metastases. 2.5. Microtubule dynamics by visualizing mitotic spindles LIMK1 and LIMK2 are also affecting microtubule dynamics, but the molecular actors involved in this process are still unknown. To observe microtubule dynamics, microtubules have been labelled with an anti-tubulin antiboby, and mitotic spindles have been observed. U2OS cells were plated on coverslips and grown for 24 hours. Inhibitors were added in the medium at a final concentration of 2.5 µM for 24 hours. Cells were then fixed in 4% formaldehyde, permeabilized in TBS-0.5% Triton-X100, and microtubules were labelled with anti-tubulin antibody. 3 compounds have been tested. Compound 15 appeared to have strong effects on microtubule dynamics: astral microtubules disappeared, spindle poles were fractionated, and microtubules depolymerized as free tubulin was diffusing in the cytoplasm and polymerized microtubule structures were lost (see Figure 4). 2.6. Dendrite plasticity by measuring their size Effect of the compounds of the invention on cytoskeleton dynamics was also assessed on specialized cells (NSC34, Mouse Motor Neuron-Like Hybrid cell line) to evaluate their effect on dendrite plasticity for neurological apllications. 40,000 NSC34 cells were seeded in 1 ml of DMEM per well (12 well plates) for 24 hours. Cells were then grown without serum to induce their differentiation in presence of 25µM of inhibitor for 24 hours. Dendrites were visualized by microscopy. 10 compounds have been tested. 4 of them strongly affected the size of the neurites showing an effect on their plasticity. 3. In vivo assay on a mouse model of ALS (Amyotrophic Lateral Sclerosis) The inventors used the SOD1-G93A transgenic mice (Jackson Laboratory, B6.Cg-Tg (SOD1*G93A)1Gur/J), consisting in a commonly used pre-clinical model for ALS, to study the effect of compound 110 in vivo. These mice express copies of the human SOD1 transgene carrying the G93A mutation and recapitulate many of the pathological features of ALS in humans, such as progressive paralysis and premature death. Mice were given Compound 110 at 10 mg/Kg (n=13) or a vehicule solution (control, n=14) by intraperitoneal injection, 2 times a week from week 8 of age until the endpoint. Body weight was monitored twice a week from week 8 until reaching the endpoint. The endpoint (survival) was reached when mice were not able to right themselves once placed on their back within 30 seconds (three times). Several tests were perfomed to evaluate the motor behaviour. The neuroscore, a scoring system (1 slighly abnormal to 4 paralysis), was used to assess hindlimb function twice a week. It was performed by observing the mouse under 3 conditions performed sequentially: the mouse was suspended by the tail, was allowed to walk, and was placed on its side. The rotarod test, evaluating the balance and motor coordination, was performed by placing mice on a rotating cylinder (5 minutes, 3 attemps). The grid test was done by placing mice on a metal grid that is later inverted to assess muscle strength (Cut-off time 90 s). The results are shown in Figures 5 and 6 The inventors showed that Compound 110 has a significant effect on delaying the loss of weight and the onset of motor symptoms (early Neuroscore stages and first time decay in the rotarod test). We do not observed improvement in later development of the disease phenotype and endpoint of the disease (survival).
