Description

[0001] IMIDAZO[4,5-B]PYRIDIN-7-AMINE COMPOUNDS BINDING AURORA KINASE A AND USES THEREOF

[0002] FIELD OF THE INVENTION

[0003] [1] The present invention relates to heterocyclic compounds that interact with Aurora Kinase A (AURKA) and thereby modulate the binding of AURKA to its interacting proteins, especially TPX2. The compounds of the present invention show high therapeutic efficiency due to its high metabolic stability and low toxicity. The present invention further pertains to pharmaceutical compositions, kits, methods for the synthesis of the compounds and various uses of such compounds, preferably in the prevention and / or treatment of proliferative diseases, such as cancer.

[0004] DESCRIPTION

[0005] [2] A major limitation in drug development is the limited therapeutic index of currently available therapies or molecularly targeted therapies. Therapeutic index measures the effectiveness of a drug in relation to its adverse effect and provides a quantifiable parameter for the relative safety of a drug. It is crucial to consider the therapeutic index of a drug, since for example, in cancer treatment, drug related toxicities often necessitate restricted drug dosing regimens, resulting in subtotal tumor remissions, which represent an important cause for tumor recurrences and the development of resistance.

[0006] [3] Cancer is a major lethal disease for humans and is caused by physiologically uncontrolled proliferation of cancer cells. Despite tremendous efforts on cancer studies and treatments over the past decades, cancer remains one of the most common causes of death in the world. Cancer affects a multitude of normal physiological conditions of the human body, resulting in serious pathological reactions that often lead to the death of the patient.

[0007] [4] Aurora kinase A (AURKA) is a serine / threonine-protein kinase that plays a key role during mitosis and meiosis. AURKA's enzymatic activity is highest during the G2 phase to M phase transition in the cell cycle, and its function is essential for a normal cell proliferation. AURKA is required for the recruitment of several important proteins necessary for the formation of the mitotic spindle, and AURKA is also necessary for the proper separation of the centrosomes after the mitotic spindle has been formed. Interestingly, AURKA has been shown to be dysregulated in several different cancer diseases, and AURKA is known to interact with multiple proteins, including MYC, P53, and TPX2. Due to its crucial role in cell proliferation disease, modulating the activity or binding of AURKA is an attractive approach in treating proliferative diseases, such as cancer.

[0008] [5] TPX2, also known as targeting protein for Xklp2, is a microtubule assembly factor that plays a key role in microtubule nucleation and growth during the mitotic phase. TPX2 is also important in activating and recruiting AURKA during mitosis. In the presence of nuclear import factor importin a, TPX2 is unable to bind to AURKA, though it is still able to bind microtubules via its amino-terminal domain, which leads to inhibition of M phase microtubule nucleation. TPX2 recruits and activates AURKA by utilizing its short 43 amino acid long amino-terminal sequence to bind the catalytic domain of AURKA, locking the kinase into its active conformation. Importantly, the interaction between AURKA and TPX2 is essential for the formation of the mitotic spindle. TPX2 is known to be overexpressed in different types of cancer including, but not limited thereto, hepatocellular carcinoma (HCC), medullary thyroid cancer, bladder carcinoma, and metastatic breast cancer.

[0009] [6] Most work currently in the state of the art on the context of AURKA and TPX2 focuses on inhibiting the binding of AURKA and TPX2 as a strategy against cancer cells.

[0010] [7] For example, McIntyre, et al. (in "Characterization of three druggable hot-spots in the Aurora-A / TPX2 interaction using biochemical, biophysical, and fragment-based approaches." ACS chemical biology 12.11 (2017): 2906-2914.) proposed druggable hotspots that disrupt the interaction between AURKA and TPX2. [8] Cole, eta / , (in "Computationally-guided optimization of small-molecule inhibitors of the Aurora A kinase- TPX2 protein-protein interaction." Chemical Communications 53.67 (2017): 9372-9375. Discloses) proposed another approach to inhibit AURKA and TPX2 interaction.

[0011] [9] Yan, et al. (in "Aurora-A kinase inhibitor scaffolds and binding modes." Drug discovery today 16.5-6 (2011): 260-269.) also speculates that inhibitors ARUKA and TPX2 could be beneficial to the discovery and optimization of enzyme inhibitors as therapeutic agents.

[0012]

[0010] Takahashi, eta / , (in "The AURKA / TPX2 axis drives colon tumorigenesis cooperatively with MYC." Annals of oncology 26.5 (2015): 935-942.) proposed inhibiting the AURKA / TPX2 axis would be a novel synthetic lethal therapeutic approach for MYC-driven cancers. "

[0013]

[0011] Other works in the state of the art have focused on decreasing the level of either the AURKA or the TPX protein. For example, Gomes-Filho, et a / , (in "Aurora A kinase and its activator TPX2 are potential therapeutic targets in KRAS-induced pancreatic cancer." Cellular Oncology 43 (2020): 445-460.) proposed the use of an siRNAbased approach to reduce the AURKA and TPX2 expression.

[0014]

[0012] However, this approach to inhibit the AURKA / TPX2 binding or to altogether decrease the expression of AURKA or TPX protein might not serve the purpose of anti-cancer therapy, especially taking into the account that the interaction of AURKA with TPX2 mostly plays a joint role in stabilizing the mitotic spindle apparatus. Accordingly, cancer cells tend to show overactivity of the AURKA / TPX2 axis, which must be curbed.

[0015]

[0013] Other works, such as Bavetsias, et a / , (in "Aurora isoform selectivity: design and synthesis of imidazo [4,5-b] pyridine derivatives as highly selective inhibitors of Aurora-A kinase in cells." Journal of Medicinal Chemistry 56.22 (2013): 9122-9135.) discloses a specific inhibitor comprising imidazo[4,5-b]pyridine derivatives of AURKA activity. However, since the kinase activity of AURKA is crucial in cell viability, directly inhibiting its kinase activity will not be applicable as a therapeutic approach due to its potential harmful side-effects.

[0016]

[0014] WO2022 / 096679 discloses anilide-based compounds that modulate the conformation of Aurora kinase A (AURKA) as well as its interactome as a promising therapeutic target for the treatment of TP53 altered liver carcinomas and TP53; RBI altered small cell lung carcinomas.

[0017]

[0015] However, the anilide based compound displays poor therapeutic efficiency, mainly due to its metabolic instability (see Figure 7B). This is mainly attributed to the functionally important, but hydrolysis labile anilide moiety.

[0018]

[0016] Therefore, it is an object of the present invention to provide metabolically stable kinase activity sparing compounds with high therapeutic index, which increase the interaction of AURKA to its binding partner, preferably TPX2 by modulating AURKA conformation, thereby selectively kill the diseased cells of target.

[0068]

[0069]

[0070]

[0071]

[0034] In one embodiment of the present invention, the compounds according to the invention are the solvates, salts, N-oxides, racemic mixtures, diastereomers, enantiomers, tautomers, isotopically labeled forms which are compounds in which one or more atoms are replaced by a corresponding atom having the same number of protons but differing in the number of neutrons, and combinations thereof of the compounds according to formula (I), (II) or (III).

[0072]

[0035] The nine-membered heterocyclic ring in the compound according to formula (I), (II) or (III) in this invention comprise, as is also evident from the formula itself, at least five carbon atoms and one nitrogen atom. The inventor has been motivated by the finding that another AURKA ligand disclosed in WO2022 / 096679 comprising an anilide moiety displays poor metabolic stability (Figure 7B), which is detrimental for clinical application. Specifically, the functionally important anilide moiety is prone to hydrolysis. However, all conventional attempts to stabilize this hydrolysis labile anilide motif by either chemical or galenic modifications failed for the flurophenyl series.

[0073]

[0036] Therefore, the present invention is based on the surprising finding that a cyclization of the anilide to a nine-member heterocyclic ring, especially an imidazopyridine stabilizes the AURKA ligand against hydrolysis while maintaining its function. In a preferred embodiment, the compound according to the invention comprises an imidazopyridine ring, wherein N and Y are both nitrogen atoms.

[0074]

[0037] So, an important embodiment of the compound in the present invention is an improved metabolic stability (Figure 7A), characterized by an in vivo or in vitro clearance half-life of at least 2 hours or longer, preferably 5 hours or longer, even more preferably 10 hours or longer, and / or is insensitive to biotransformation by drugmetabolizing enzyme, in particular human hepatic microsomal enzyme, such as CYP.

[0038] The clearance time should be understood in the context of the invention as the time it takes for the concentration of the compound to drop below a certain level after administering said compound either in vivo, such as though ingestion of the compound, or in vitro, such as by adding the compound to the culture medium. Accordingly, the clearance half-life refers to the time it takes for the concentration compound to drop to 50% of the concentration at the time of administration, either in-vivo or in-vitro.

[0075]

[0039] In another important embodiment of the compound according to the invention, a compound comprising a nine-membered heterocyclic ring according to formula (I), (II) or (III) solves the above problems by specifically modulating the conformation of AURKA, thereby modifying the protein-protein interaction of AURKA with binding proteins, such as MYC and / or TPX2. In the context of the current invention, this specific modulating may refer to change in secondary structure or change in protein dynamics, to achieve the functional effect of increase the interaction between AURKA and its binding partners, preferably with TPX2.

[0076]

[0040] Yet another particularly preferred embodiment relates to a compound according to this invention, wherein the compound is capable of binding, preferably of specifically binding, to a serine / threonine kinase. According to this invention, the compound is capable of binding, preferably of specifically binding, to any serine / threonine kinase. A particularly preferred serine / threonine kinase, in the context of this invention, is Aurora Kinase A (AURKA), or a variant thereof.

[0077]

[0041] A further preferred embodiment relates to a compound according to this invention, wherein the compound modulates, stabilizes and / or destabilizes, preferably specifically modulates, stabilizes and / or destabilizes, the conformation of the serine / threonine kinase, preferably of AURKA, or the variant thereof.

[0078]

[0042] Additionally preferred is a compound, wherein the compound modulates, preferably specifically modulates, more preferably specifically stabilizes an interaction of the serine / threonine kinase, preferably of AURKA, or the variant thereof, with at least one binding protein.

[0079]

[0043] The expression "modulates" as used herein means that upon administration of a compound according to this invention, the conformation of AURKA is altered, preferably because the compound is inducing a conformational shift in AURKA. Thereby, the compound is modulating, i.e., altering, the binding of at least one binding protein, such as MYC and / or TPX2, to AURKA. Accordingly, the term "modulates" further refers to inducing a shift in the protein-protein interaction (PPI) of AURKA with at least one binding protein, such as a change of the binding of MYC and / or TPX2 to AURKA.

[0080]

[0044] The expression "stabilizes" as used herein means that upon administration of a compound according to this invention, a certain conformational state of the serine / threonine kinase, preferably of AURKA, is more likely kept in that particular state than altered into a different conformational state, i.e., the likelihood of a conformational shift of the serine / threonine kinase, preferably of AURKA, is reduced or prevented. The term "stabilizes" can also refer to locking a serine / threonine kinase, preferably AURKA, into a particular conformation. The expression "stabilizes" as used herein further refers to inducing an enhanced binding of certain binding proteins to the serine / threonine kinase, preferably to AURKA. For example, the compounds of this invention may stabilize the binding of TPX2 to AURKA.

[0081]

[0045] The expression "destabilizes" as used herein means that upon administration of a compound according to this invention, a certain conformational state of the serine / threonine kinase, preferably of AURKA, is more likely altered into a different conformational state than kept or locked in that particular conformational state, i.e., the likelihood of a conformational shift of the serine / threonine kinase, preferably of AURKA, is enhanced or enforced. The term "destabilizes" can also refer to inducing a conformational shift in the serine / threonine kinase, preferably of AURKA.

[0082]

[0046] Simultaneously, the use of a compound comprising a nine-membered heterocyclic ring according to formula (I), (II) or (III) as above is characterized by a largely reduced or no inhibition of the kinase activity of AURKA, making the novel compounds comprising a nine-membered heterocyclic ring according to formula (I), (II) or (III) of this invention useful for treating various cancer diseases, such as HCC and SCLC.

[0083]

[0047] Additionally, the compound comprising a nine-membered heterocyclic ring is characterized by the high specificity to AURKA, in that it does not bind promiscuously to other kinases, modulate the conformation of other kinases, or inhibit their kinase activities. This is evidenced by the the fact that there was no hit for kinase inhibition from a panel against 345 wt-kinases at Compound-Concentrations of 300 nM and 1000 nM.

[0084]

[0048] The in-vivo efficacy of the compound according to the present invention has been demonstrated by the inventor using different mouse models. In a mouse lung cancer model, in particular a mouse small cell lung cancer (SCLC) model, the compound according to the present invention is shown to reduce the tumor volume in a small cell lung cancer mouse model by at least 75%, and improve subject survival duration by at least 50%. In a mouse liver cancer model, the compound according to the present invention is shown to improve the subject survival duration by at least 40% compared with a control, and by at least 17% compared with another drug Alisertib.

[0085]

[0049] As used herein, the term "therapeutically effective amount" shall refer to the amount of a compound or a combination of different compounds that will elicit the biological or medical response of a tissue, system, animal or human subject that is being sought, for instance, by a researcher or clinician, in accordance with the herein disclosed invention. Furthermore, the term "therapeutically effective amount" means any amount which, as compared to a corresponding subject who has not received such an amount of a compound or a combination of different compounds according to this invention, results in improved treatment, healing, prevention, or amelioration of a disease, disorder, or side effect, or a decrease in the rate of advancement of a disease or disorder.

[0086]

[0050] The invention extends isotope labelled forms of the compounds comprising a nine-membered heterocycle according to formula (I), and / or a compound having formula (II), and / or a compound having formula (III), or any other compound of this invention. As used herein, the term "isotope" refer to atoms of the same element that have the same number of protons, but a different number of neutrons. The term "isotope labeling" therefore accordingly referred substituting an atom with another of the same element, i.e. with the same proton number, but a different number of neutrons. For example, deuterium is an isotope of hydrogen comprising one proton, and one neutron. A "deuterium labeled" compound therefore refer to a compound with the same chemical structure, but with one or more hydrogen atom being substituted by deuterium. As used herein, the terms "isotope labeled" and "isotope substituted" are interchangeable.

[0087]

[0051] In the invention, the term "Example X ", wherein X is any natural number, shall refer to the example compound with the corresponding number X as listed in Table 1. For example, Example 1, if according to the context should refer to a compound would refer to the compound with the IUPAC naming of 4 / -(4-(l / 7-pyrazol-4- yl)benzyl)-2-(phenoxymethyl)-l / 7-benzo[ 7|imidazol-5-amine, as defined in Table 1.

[0088]

[0052] In another important embodiment, the use of a compound comprising a nine-membered heterocyclic ring according to formula (I), (II) or (III) as above is characterized by a superior therapeutic index. In the context of the current invention, a therapeutic index is a measurement of the margin of safety that exists between the dose of a drug that produces the desired effect and the dose that produces unwanted and possibly dangerous side effects. Formally, it can be defined as the ratio between the median lethal dose (LD50) and the median effective dose (ED50) in animals or defined as the ratio between the median growth inhibition concentration of healthy cells and the effective concentration in killing of disease cells, specifically cancer cells. Compounds which exhibit large therapeutic indices are preferred. While compounds that exhibit toxic side effects may be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects.

[0089]

[0053] In one related embodiment, the compound comprising a nine-membered heterocyclic ring according to formula (I), (II) or (III) is non-toxic to healthy cells, with median growth inhibition concentration of at least 10 uM or higher, preferably 20 uM or higher, or even more preferably 50 uM or higher in healthy cells. In the present invention, the median growth inhibition concentration is the concentration required to kill half of the test subjects, such as healthy cells, after a certain test duration.

In the present invention, the median effective concentration is the concentration required to eliminate half of the diseased cells, such as cancer cells, after a certain test duration.

[0091]

[0055] Therefore, in an important embodiment, the compound comprising a nine-membered heterocyclic ring according to formula (I), (II) or (III) has a therapeutic index of at least 10 or higher, preferably 20 or higher, more preferably 50 or higher, more preferably 100 or higher or even more preferably 500 or higher.

[0092]

[0056] Additionally, the invention shall further include any pharmaceutically acceptable salt of the compounds mentioned above. The pharmaceutically acceptable salts are either acid or base addition salts of a compound as above, with pharmaceutically acceptable acids or bases. According to this invention, any suitable pharmaceutically acceptable organic and inorganic acid may be used, such as, for example, sulfuric acid, sulfamic acid, hydrochloric acid, hydrobromic acid, phosphoric acid, dicarboxylic acids, tricarboxylic acids and hydroxycarboxylic acids having 2 to 10 carbon atoms, such as oxalic acid, malonic acid, maleic acid, fumaric acid, lactic acid, citric acid, and benzoic acid, CrC4-alkylsulfonic acids, such as methanesulfonic acid, cycloaliphatic sulfonic acids, such as S-(+)-10-camphor sulfonic acid, or aromatic sulfonic acids, such as benzenesulfonic acid and toluenesulfonic acid. Further, any suitable pharmaceutically acceptable organic and inorganic base may be used according to this invention, such as, for example, ammonium hydroxide, alkali metal hydroxides, such as sodium hydroxide or potassium hydroxide, alkaline earth metal hydroxides, such as calcium or magnesium hydroxide, or organic nitrogen bases, such as dimethylamine, trimethylamine, ethanolamine, diethanolamine, triethanolamine, choline, procaine, arginine, or ethylenediamine.

[0093]

[0057] According to the present invention, solvates of the above compounds are also within the scope of this invention. One example of solvates are hydrates, but any other solvate shall also be included.

[0094]

[0058] It is to be understood that in any embodiment of the invention, where the compound comprising a ninemembered heterocycle according to formula (I), (II) or (III), and / or a compound having formula (II), and / or a compound having formula (III), comprises at least one chiral center, e.g. an asymmetric carbon atom, the invention extends to all the optical isomers thereof, as well as to racemates and to isomer mixtures thereof, wherein any isomer or any number of isomers may be present in any amount. Examples of optical isomers are enantiomers and diastereomers, which shall also be included in the present invention. Further, the invention also extends to all tautomeric, crystal and / or polymorphic forms of the compounds comprising a nine-membered heterocycle according to formula (I), and / or a compound having formula (II), and / or a compound having formula (III), or any other compound of this invention.

[0095]

[0059] According to the present invention, prodrugs of the compounds above shall also be included. The term "prodrug" or "pro-drug" shall relate to a compound or an agent that can be transformed into the actual active compound. Such transformation usually occurs in the human or animal body through a physicochemical transformation process, such as an enzymatic or chemical cleavage. Candidate enzymes that could be utilized to activate the prodrugs according to the present invention include lipases, proteases or glycosidases. Importantly, prodrugs can be designed so that the transformation process occurs in particular tissues or regions of the human or animal body. Without being limited thereto, an example of a prodrug of a compound according to the present invention is any compound as above in form of an ester, or a compound comprising a carboxylic acid substituent wherein the free hydrogen is replaced by an alkyl, such as alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, l-methyl-l-(alkoxycarbonyloxy)-ethyl having from 5 to 8 carbon atoms, (Ci-C6)alkanoyloxy-methyl, piperidine-, pyrrolidino- or morpholino(C2-C3)alkyl, or arylactyl.

[0096]

[0060] According to the present invention, it might be beneficial to use a prodrug of a compound of this invention, because said prodrug might be more soluble in a liquid, such as more water soluble, than the ultimate active compound. Also, a different route of administration available for a pro-drug might be beneficial over the required route of administration of the final drug. For example, a pro-drug may be administrable by intravenous administration. Moreover, the penetration of certain organs might differ between final drug and prodrug. For example, a prodrug might be able to cross the blood-brain-barrier, whereas the active end-drug might not. Also, bioavailability of a prodrug might be advantageous over bioavailability of the final drug.

Exemplary homocyclic aromatic ring groups include cyclopropenylium, cyclopentadienyl, phenyl, indenyl, naphthyl, azulenyl, fluorenyl, anthryl, and phenanthryl.

[0103]

[0067] Such aromatic rings can also be heterocyclic, which means an aromatic ring as defined above, in which one or more carbon atoms in the aryl group are replaced by heteroatoms (such as 0, S, or N). In particular, a heteroaromatic or heteroaryl group comprises at least one nitrogen atom as a ring member. In addition, the heteroaromatic or heteroaryl group can, besides the at least one nitrogen atom, further include an oxygen and / or a sulfur atom as ring member.

[0104]

[0201] BRIEF DESCRIPTION OF THE FIGURES AND SEQUENCES

[0202] The figures show:

[0203]

[0108] Figure 1: shows (A) Crystal violet colony formation assay of NMP19- / - or NMP53 murine hepatocellular carcinoma cells. In brief, cells were seeded in 6-well plates on day 1. On day 2, cells were treated with either EXAMPLE 3 (AURKA Ligand) or with DMSO (control). After 5 days, wells were washed and cells were fixed with 4% PFA and then stained with Crystal Violet solution. Plates were scanned and pictures were saved. (B) Crystal violet colony formation assay of NMP19- / - or NMP53 murine hepatocellular carcinoma cells. In brief, cells were seeded in 6-well plates on day 1. On day 2, cells were treated with MLN8237 (AURKA inhibitor) or with DMSO (control). After 5 days, wells were washed and cells were fixed with 4% PFA and then stained with Crystal Violet solution. Plates were scanned and pictures were saved. (C) AURKA kinase assay with the AURKA ligand EXAMPLE 3. The AURKA kinase assay was performed by Reaction Biology Corp, and it is based on radiometric ATP quantification. Compounds were received as 10 mM stock. Compounds were tested in 10-dose IC50 mode with a 3-fold serial dilution starting at 10 pM. Control compound, Staurosporine, was tested in 10-dose IC50 mode with 4-fold serial dilution starting at 20 pM. Reactions were carried out at 10 pM ATP. (D) Growth curves of NMP19 / _, NMP53 / _and BNL CL.2 (nontransformed murine embryonic liver cell line). Cells were seeded in 96-well plates on day 1. On next day, they were treated with corresponding EXAMPLE 3 concentrations and left to grow for 48h. Afterwards, an XTT cell viability assay was performed, based on the quantification of metabolic activity of alive cells. Values were fitted in a response curve after normalization to DMSO treated cells and logarithmic transformation. (E) Bar graph corresponds to the growth inhibition in percentage of the IC95 concentration of EXAMPLE 3 against NMP53 cells. At the IC95 of NMP53- / • (HCC cells), no significant growth inhibition is seen on non-sensitive HCC NMP19 / _and on non-transformed BNL CI.2 cells.

[0204]

[0109] Figure 2: shows (A) Schematic representation of Co-Immunoprecipitation assay. NMP53- / -cells were genetically engineered to express FLAG-AURKA induced by Doxycycline. Cells were either treated with DMSO (control) or AURKA Ligand (AURKA INHIBITOR). Antibodies against FLAG were used to precipitate AURKA together with proteins bound to AURKA. AURKA-binding partners that were enriched in the eluate, were sent for LC-MS analysis. (B) Binding partners with increased binding to FLAG-AURKA under AURKA INHIBITOR treatment were identified. From those, TPX2 was the only protein partner of AURKA that was already described. (C) Schematic representation of a Cellular Thermal Shift Assay (CETSA) used to confirm indirectly confirm stabilization of AURKA / TPX2 complex induced by AURKA ligand treatment. Cells were either treated with EXAMPLE 3 or DMSO (control). A heat gradient was applied to cells followed by lysis to isolate the soluble protein fraction. An SDS-Page was then run to identify the levels of non-melted proteins of interest under the treatment of AURKA ligand / DMSO (AURKA Ligand / Control). (D) SDS-Page results of NMP53 / _cells treated with EXAMPLE 3 and subsequently heated to the temperatures stated. Both AURKA and TPX2 are stabilized at 43.7- 47.9 °C. (E) Quantification of the bands shown on D. using the densitometer of Image Lab software.

[0110] Figure 3: shows (A) Representative pictures of alpha Tubulin staining (red) with DAPI (DNA, blue). Mitotic cells shown, are categorized to normal (bipolar) and abnormal (multipolar, weak, without nucleation). In brief, cells were grown in 4-chamber coverslips under treatment of EXAMPLE 3 or DMSO (control). After certain time points, cells were fixed, permeabilized and stained with antibody against alpha-Tubulin. Afterwards a secondary antibody was added, against the primary together with DAPI. Finally, slides were mounted and analyzed in a fluorescent microscope. Bar graphs represent quantification of abnormal / normal spindles levels of (B) NMP53 / _and (C) NMP19 / _mitotic cells at time points after treatment with 15 nM of EXAMPLE 3. Pictures taken in an immunofluorescence microscope (as seen on A.) were used for the quantification. (D) Cell cycle analysis of NMP53 and NMP19 cells. Cells were isolated after treatment with EXAMPLE 3, and then stained with Propidium Iodine. Subsequently, they were analyzed in a Flow Cytometry device for quantification of the amount of PI in each cell. Cells were then quantified according to PI amount, which corresponds to certain cell cycle states.

[0208]

[0113] Figure 6: shows AURKA-inhibition data of selected compounds. The AURKA-inhibition assay was performed by Reaction Biology Corp, and it is based on radiometric ATP quantification. Compounds were received as 10 mM stock. Compounds were tested in 10-dose IC50 mode with a 3-fold serial dilution starting at 10 pM. Control compound, Staurosporine, was tested in 10-dose IC50 mode with 4-fold serial dilution starting at 20 pM. Reactions were carried out at 10 pM ATP.

[0209] Figure 7: shows (A) Metabolic stability of selected compounds in Mouse Liver Microsomes (MLM). Metabolic stability assays were performed in the presence of an NADPH-regenerating system consisting of 5 mM glucose-6- phosphate, 5 U / mL glucose-6 -phosphate dehydrogenase, and 1 mM NADP+. Liver microsomes (20 mg / mL), NADPH-regenerating system, and 4 mM MgCh'6 H2O in 0.1 M TRIS-HCl-buffer (pH 7.4) were preincubated for 5 min at 37 °C and 750 rpm on a shaker. The reaction was started by adding the preheated compound at 10 mM resulting in a final concentration of 0.1 mM. The reaction was quenched at selected time points (0, 10, 20, 30, 60, and 120 min) by pipetting 100 pL of internal standard (ketoprofen) in acetonitrile. The samples were vortexed for 30 s and centrifuged. The supernatant was used directly for LC-MS analysis. All compound incubations were conducted at least in triplicates. Additionally, a negative control containing BSA (20 mg / mL) instead of liver microsomes and a positive control using Verapamil instead of compound were performed. Shown is the remaining unmetabolized percentage of compound in relation to the original loading quantity (equal to 100%). A value of 80% therefore means that 80% of the compound quantity could still be detected unmetabolized after timepoint x. If the m / z ratios of possible metabolites could be detected, their percentages were indicated as Ml for metabolite 1; M2 for metabolite 2 etc.; (B) shows metabolic stability of selected compounds in Human Liver Microsomes (HLM) and a comparative experiment with anilide-based compounds of WO 2022 / 096679.

[0115] The examples show: Example 1: Due to the growth inhibition values it is clear that the compounds of the invention inhibit p53-altered carcinoma with high selectivity over other liver cell lines. Besides this the selectivity of the AURKA-Ligands of the invention compared with the AURKA-Inhibitor Alisertib (MLN8237) in p53 altered HCC is also remarkably higher without inhibition the enzymatic function of AURKA (Figure 1).

[0213] Based on the western blot data it is clearly visible that there is a ligand-dependent stabilization of AURKA and TPX2 (Figure 2).

[0214] Based on the data from Figure 3, it is clear that the ligands of the invention have a strong effect on the spindle assembly even at low concentrations and modify it sustainably over 24 h in p53-deficient cells in favor of abnormal spindles. The return to physiological states is achieved more quickly in p53-functional cells (Figure 3).

[0215] The data from Figure 4 show both the high metabolic stability of the molecules of this invention in murine liver microsomes and the very good pharmacokinetic properties of the novel molecules of this invention, which have plasma concentrations after i.v., i.p. and peroral application that correspond to a multiple of the EC50 concentration over a period of 24 h.
