Description

Technical Field

[0001] The present disclosure relates to a CHK1 inhibitor, a liposome encapsulating a CHK1 inhibitor, or a combined use of these and an immune checkpoint inhibitor as a therapeutic agent for cancers showing resistance to treatment with an immune checkpoint inhibitor. Background Art

[0002] CHK1 is a serine / threonine protein kinase located downstream of ATR in the checkpoint signal transduction pathway of DNA damage in the cell cycle. In mammalian cells, CHK1 is phosphorylated in an ATR-dependent manner in response to DNA damage caused by ionizing radiation, etc., or DNA replication stress caused by excessive cell proliferation and genomic instability in cancer cells, etc. (Non-patent Documents 1 to 5). CHK1 phosphorylates CDC25A by activating this phosphorylation of CHK1, inhibiting the dephosphorylation of cyclin E / CDK2 caused by CDC25A, and stopping the progression from the S phase. In addition, CHK1 phosphorylates CDC25C, inhibiting the dephosphorylation of cyclin B / CDK1 caused by CDC25C, and stopping the progression from the G2M phase. In any case, the control of CDK activity will induce the arrest of the cell cycle, preventing cell division in the presence of DNA damage, thereby promoting the repair of DNA damage. CHK1 inhibits the checkpoint function that suppresses DNA damage during the cell cycle in cancer cells, thereby causing incomplete DNA repair and uncontrolled DNA synthesis in the presence of DNA damage, ultimately inducing DNA fragmentation, replication catastrophe, and cell death (Patent Documents 1-2).

[0003] Since its launch, immune checkpoint inhibitors have established themselves as the fourth therapy for cancer treatment, following surgery, radiotherapy, and chemotherapy. These immune checkpoint inhibitors are currently approved for use in a wide range of cancer types, including melanoma. As a characteristic of their effectiveness, a long-term survival effect (Durable Clinical Response) has been reported, but this effect has only been found in some patients, such as the 13.3% total efficacy of nivolumab in head and neck squamous cell carcinoma, and improvements in efficacy are being sought (Non-Patent Document 7).

[0004] Various inhibitors of CHK1 have been reported (Patent Documents 1 to 3).

[0739] Effects of the Invention

[0740] According to the present disclosure, a therapeutic agent and / or preventive agent for cancer patients who show resistance to treatment with immune checkpoint inhibitors can be provided, containing a CHK1 inhibitor or a liposome encapsulating a CHK1 inhibitor as an active ingredient. Furthermore, when the aforementioned inhibitor or liposome is used in combination with an immune checkpoint inhibitor, a superior anti-tumor effect is shown compared to a single agent. In addition, the aforementioned inhibitor, the aforementioned liposome, or their combination with an immune checkpoint inhibitor also shows an effect of preventing the recurrence of cancer that has been alleviated.

[0741] According to the present disclosure, a CHK1 inhibitor comprising a 5-heteroaryl-1H-pyrazole-3-amine derivative or a pharmaceutically acceptable salt thereof can be provided. The compounds disclosed herein have both excellent CHK1 inhibitory activity and high safety. By being encapsulated in liposomes and slowly released from the liposomes, they can act continuously on cancer, demonstrating a potent anti-tumor effect. The compounds disclosed herein are useful as therapeutic agents for diseases in which CHK1 is involved, and specifically, can be applied to patients with pancreatic cancer, ovarian cancer, osteosarcoma, Ewing sarcoma, chondrosarcoma, or soft tissue sarcoma.

[0742] In the present disclosure, compared with 5-phenyl-1H-pyrazole-3-amine derivatives, namely Prexasertib, although Prexasertib showed a pharmacological effect in a Phase 2 trial on patients with ovarian cancer, it did not achieve the maximum efficacy of 72 hours of continuous exposure as inferred from non-clinical trials. In contrast, the compounds disclosed herein or their salts can further improve it. Moreover, when administered once, compared with Prexasertib, which has side effects due to high maximum blood concentrations, the compounds or salts disclosed herein do not have such side effects. When administered continuously for three days, compared with side effects caused by long-term drug exposure, the compounds or salts disclosed herein did not find such side effects (non-patent literature 3, non-patent literature 6). In addition, the inventors of the present application and others newly discovered that Prexasertib has the risk of hepatotoxicity, and the compounds of the present invention can reduce the risk of hepatotoxicity. In summary, the compounds disclosed herein have both excellent CHK1 inhibitory activity and high safety.

[0743] In particular, compounds represented by formula (3) having a pyridine ring with a nitrogen atom at a specific position have the characteristics of having both high antitumor activity and safety and excellent pharmacokinetics.

[0744] In particular, the compound of Example 1 encompassed by formula (3) exhibits the following characteristics compared to prisertib: it exhibits high CHK1 inhibitory activity, has a potent cell proliferation inhibitory effect, and is highly safe. Furthermore, the compound of Example 1 exhibits favorable pharmacokinetics and can be effectively encapsulated in liposomes. The liposome formulation of the compound of Example 1 exhibits excellent antitumor effects and is highly safe, and can further exert a more specific antitumor effect by combining it with known anticancer agents.

[1292] In the production methods described above, starting materials or intermediates for which the production methods are not described are commercially available, or can be synthesized from commercially available compounds by methods known to those skilled in the art or by methods in accordance therewith.

[1293] In each reaction of the production method described above, unless the use of a protecting group is specifically indicated, a protecting group may be used as needed. For example, if any functional group other than the reaction site is altered under the described reaction conditions, or if the described method is not suitable without a protecting group, the target compound can be obtained by protecting the site other than the reaction site and then deprotecting it after the reaction is completed or after a series of reactions.

[1294] As the protecting group, for example, the protecting group described in Protective Groups in Organic Synthesis (written by Theodora W. Greene, Peter G.M. Wuts, published by John Wiley & Sons, Inc. in 1999) can be used. As a specific example of the protecting group of amino, for example, benzyloxycarbonyl, tert-butyloxycarbonyl, acetyl, benzyl, etc. can be enumerated. In addition, as a specific example of the protecting group of hydroxyl, for example, trialkylsilyl groups such as trimethylsilyl and tert-butyldimethylsilyl, acetyl, benzyl, etc. can be enumerated.

[1295] The introduction and removal of the protecting group can be carried out by methods commonly used in organic synthetic chemistry (see, for example, the aforementioned Protective Groups in Organic Synthesis) or methods in accordance therewith.

[1296] In this specification, protecting groups, condensing agents, etc. may be represented by IUPAC-IUB (Commission on Biochemical Nomenclature) abbreviations commonly used in this technical field. It should be noted that the compound names used in this specification do not necessarily follow the IUPAC nomenclature.

[1297] The intermediates or target compounds in the above-described production methods can also be derived into other compounds included in the present disclosure by appropriately modifying their functional groups (e.g., protecting and deprotecting the functional groups as needed, and performing various transformations starting with amino, hydroxyl, carbonyl, halogen, etc.). Functional group transformations can be performed by commonly used general methods (e.g., see Comprehensive Organic Transformations, R.C. Larock, John Wiley & Sons Inc. (1999)).

[1298] The intermediates and target compounds in the above-described production methods can be isolated and purified by purification methods commonly used in organic synthetic chemistry (e.g., neutralization, filtration, extraction, washing, drying, concentration, recrystallization, various chromatography methods, etc.). In addition, the intermediates can be used in subsequent reactions without special purification.

[1299] Examples of "pharmaceutically acceptable salts" include acid addition salts and base addition salts. For example, acid addition salts include inorganic acid salts such as hydrochlorides, hydrobromides, sulfates, hydroiodides, nitrates, and phosphates, or organic acid salts such as citrates, oxalates, phthalates, fumarates, maleates, succinates, malates, acetates, formates, propionates, benzoates, trifluoroacetates, methanesulfonates, benzenesulfonates, p-toluenesulfonates, and camphorsulfonates. Base addition salts include inorganic base salts such as sodium salts, potassium salts, calcium salts, magnesium salts, barium salts, and aluminum salts, or organic base salts such as trimethylamine, triethylamine, pyridine, picoline, 2,6-lutidine, ethanolamine, diethanolamine, triethanolamine, tromethamine [tris(hydroxymethyl)methylamine], tert-butylamine, cyclohexylamine, dicyclohexylamine, and N,N-dibenzylethylamine. Furthermore, "pharmaceutically acceptable salts" include amino acid salts with basic amino acids or acidic amino acids such as arginine, lysine, ornithine, aspartic acid, or glutamic acid.

[1300] Suitable salts of starting materials and intermediates and acceptable salts as pharmaceutical raw materials are conventional non-toxic salts. As these salts, for example, except organic acid salts (such as acetate, trifluoroacetate, maleate, fumarate, citrate, tartrate, methanesulfonate, benzenesulfonate, formates, toluenesulfonate etc.) and inorganic acid salts (such as hydrochloride, hydrobromide, hydroiodide, sulfate, nitrate, phosphate etc.), with amino acid (such as arginine, aspartic acid, glutamic acid etc.) salts, alkali metal salts (such as sodium salt, potassium salt etc.), alkaline earth metal salts (such as calcium salt, magnesium salt etc.) metal salts, ammonium salts, organic base salts (such as trimethylamine salt, triethylamine salt, pyridinium salt, picoline salt, dicyclohexylamine salt, N,N'-dibenzylethylenediamine salt etc.), etc., those skilled in the art can suitably select.

[1301] In the present disclosure, any one or two or more of the compounds represented by formula (1) to (5) 1 H is transformed into 2 Deuterated forms obtained by reacting H(D) are also included in the compounds represented by formulae (1) to (5).

[1302] The present disclosure includes compounds represented by formulas (1) to (5) or pharmaceutically acceptable salts thereof. Furthermore, the compounds of the present disclosure may exist in the form of hydrates and / or solvates with various solvents (e.g., ethanolates), and such hydrates and / or solvates are also encompassed by the compounds of the present disclosure.

[1303] Furthermore, the compounds of the present disclosure also include all possible isomers such as optical isomers based on optically active centers, atropisomers based on axial or planar chirality resulting from restraint of intramolecular rotation, other stereoisomers, tautomers, geometric isomers, and all forms of crystal forms, and mixtures thereof.

[1304] Particularly optical isomers and atropisomers can be obtained as racemates, or when using optically active starting materials or intermediates, can be obtained as optically active forms. In addition, as required, at the appropriate stage of the aforementioned manufacturing method, the racemate of the corresponding raw material, intermediate or final product can be physically or chemically split into their optical enantiomers by using known separation methods such as the method using an optically active column, fractional crystallization, etc. As their separation methods, for example, a racemate is reacted with an optically active resolving agent to synthesize two diastereomers, and the difference in physical properties is utilized to separate the diastereomers by methods such as fractional crystallization, etc.

[1305] When a pharmaceutically acceptable salt of the compound of the present disclosure is desired, when the compound represented by formula (1) to (5) is obtained as a pharmaceutically acceptable salt, it is sufficient to purify it directly. Alternatively, when it is obtained in a free form, it is sufficient to dissolve or suspend it in a suitable organic solvent, add an acid or a base, and form a salt by a conventional method.

[1306] Liposomes encapsulating the compounds of the present disclosure can be produced, for example, by the following method.

[1307] [Process 1]

[1308] The membrane components such as phospholipids and cholesterol are dissolved in organic solvents such as chloroform, and the organic solvent is removed by distillation in a flask, thereby forming a film of lipid mixture on the inner wall of the flask. As above-mentioned substitution, it is also possible to be dissolved in tert-butyl alcohol etc., then freeze-dried, thereby obtaining lipid mixture as a freeze-dried product. In addition, after the membrane components such as phospholipids and cholesterol are dissolved in an organic solvent, using instant vacuum drying device CRUX (Hosokawa Micron Co., Ltd. system), it is also possible to obtain powdered lipid mixture, which can be obtained by Japan Seika Co., Ltd. under the name of Presome (registered trademark).

[1309] [Process 2]

[1310] An internal aqueous phase solution such as an aqueous ammonium sulfate solution is added to the lipid mixture obtained in step 1 and dispersed to obtain a crude liposome dispersion.

[1311] [Process 3]

[1312] The crude liposome dispersion obtained in step 2 is passed through a filter using an extruder to obtain the desired particle size. Alternatively, the crude liposome dispersion obtained in step 2 is discharged from a nozzle under high pressure using a high-pressure homogenizer to obtain the desired particle size. The particle size of the liposome is not particularly limited, and is, for example, 10 nm to 200 nm, preferably 30 nm to 150 nm, more preferably 40 nm to 140 nm, further preferably 50 to 120 nm, and most preferably 60 to 100 nm. The particle size of the liposome is an average value measured by dynamic light scattering, for example, using a Zetasizer Nano ZS (Malvern Instruments).

[1313] [Process 4]

[1314] The liposome solution obtained in step 3 is subjected to gel filtration, dialysis, tangential flow filtration, ultracentrifugation or the like to replace the external aqueous phase.

[1315] [Process 5]

[1316] The liposome solution obtained in step 4, in which the external aqueous phase has been replaced, is incubated with the compound to be encapsulated, thereby encapsulating the compound in the liposome.

[1317] [Process 6]

[1318] The obtained compound-encapsulated liposomes are subjected to gel filtration, dialysis, tangential flow filtration, or ultracentrifugation to remove unencapsulated compounds. If the desired encapsulation efficiency is obtained in step 5, step 6 can be omitted.

[1331] The cell growth factor in the drug that inhibits the action of the cell growth factor and its receptor may be any substance as long as it promotes cell proliferation. It is usually a peptide with a molecular weight of 20,000 or less, and includes factors that act at low concentrations by binding to receptors. Specific examples include: EGF (epidermal growth factor) or a substance having substantially the same activity therewith (for example, TGFalpha, etc.), insulin or a substance having substantially the same activity therewith (for example, insulin, IGF (insulin-like growth factor)-1, IGF-2, etc.), FGF (fibroblast growth factor) or a substance having substantially the same analysis therewith (for example, acidic FGF, basic FGF, KGK (keratinocyte growth factor), FGF-10, etc.), and other cell growth factors (for example, CSF (colony stimulating factor), EPO (erythropoietin), IL-2 (interleukin-2), NGF (nerve growth factor), PDGF (platelet-derived growth factor), TGF-β (transforming growth factor β), HGF (hepatocyte growth factor), VEGF (vascular endothelial growth factor), heregulin, angiogenin, etc.).

[1333] "Showing resistance to treatment with immune checkpoint inhibitors" means a state in which, in solid tumors, tumor growth cannot be suppressed even with the administration of immune checkpoint inhibitors. Showing resistance to anti-PD-1 antibodies means a state in which, even with the administration of the aforementioned anti-PD-1 antibodies, tumor growth cannot be suppressed. Showing resistance to anti-PD-L1 antibodies means a state in which, even with the administration of the aforementioned anti-PD-L1 antibodies, tumor growth cannot be suppressed. In blood cancers, it means a state in which, even with the administration of immune checkpoint inhibitors, the increase in the number of cancer cells in the blood cannot be suppressed. Showing resistance to anti-PD-1 antibodies means a state in which, even with the administration of the aforementioned anti-PD-1 antibodies, the increase in the number of cancer cells in the blood cannot be suppressed. Showing resistance to anti-PD-L1 antibodies means a state in which, even with the administration of the aforementioned anti-PD-L1 antibodies, the increase in the number of cancer cells in the blood cannot be suppressed.

[1334] Anti-PD-1 antibodies are proteins that recognize PD-1 molecules. They have a Y-shaped four-chain structure (two light and two heavy polypeptide chains) and selectively recognize a single PD-1 molecule through their Fab site. Anti-PD-1 antibodies can be produced by preparing hybridomas by fusing antibody-producing B cells with myeloma cells and purifying the antibodies secreted from the culture supernatant.

A higher value indicates a more inflammatory environment within the tumor, meaning that anti-PD-1 / PD-L1 antibodies are more likely to be effective.

[1336] Solid cancers with a high tumor mutation burden (TMB-High) refer to cancers in which the TMB score measured in the FoundationOne CDx Cancer Genomic Profile shows 10 mut / Mb or higher.

[1337] Patients who are responsive to anti-PD-1 antibodies are considered to have tumor growth suppressed by anti-PD-1 antibody administration.

Among them, the compounds of Examples 1 and 8 had a particularly potent and specific effect of inhibiting CHK1 activity.

[1653] Experimental Example 2: Cell proliferation inhibition experiment

[1654] ES-2 cells were obtained from the American Culture Collection Center (ATCC) and cultured at 37°C in the presence of 5% CO2 using McCoy's 5a medium containing 10% fetal bovine serum and 1% penicillin / streptomycin.

[1655] 500 cells were seeded per well in a 384-well plate, and the compound to be evaluated was added to a final DMSO concentration of 0.1%, and cultured for 2 days. After the culture was completed, the cell viability was calculated using CellTiter-Glo (registered trademark) 3D reagent (Promega, G968B). Based on the survival curve, the IC value of the concentration of the compound to inhibit cell proliferation by 50% was calculated. 50 Note that ES-2 cells are known to show cisplatin resistance.

[1662] The compounds obtained in the examples and prisertib were subjected to the test shown in Test Example 3. In addition, the hERG IC values ​​obtained in Test Example 3 were used to determine the compounds of the examples. 50 Divide by the IC50 of CHK1 inhibition obtained in Experiment 1 50 The obtained value was calculated as hERG / CHK1.

[1668] These six compounds showed a deviation of more than 18 times compared to prisertib, and possessed specific effects with high safety.

[1669] Experimental Example 4: Evaluation of CYP3A4 MBI and Enzyme Inactivation Clearance

[1670] Cytochrome P450 (CYP) is the most important enzyme group involved in drug metabolism, and many pharmacokinetic interactions are based on the inhibition of these CYP activities. CYPs exist in a variety of molecular species, with CYP3A4 in particular being the most involved in drug metabolism among CYP oxidation reactions and accounting for the majority of CYPs present in the liver.

[1671] There are two main types of CYP inhibition: reversible inhibition and irreversible inhibition (mechanism-based inhibition: MBI). In particular, MBI-based CYP inhibition is known to cause not only drug interactions but also serious side effects (hepatotoxicity, etc.) (Curr Opin Drug Discov Devel. 2010 January, 13(1), 66-77, Therapeutics and Clinical Risk Management, 2005, 1(1), 3-13).

[1672] The MBI and enzyme inactivation clearance of CYP3A4 were evaluated using the compound of this example and prisertib.

[1673] The inhibitory effect and inhibition pattern of the test compound on CYP3A4 were evaluated using human liver microsomes as the enzyme source and midazolam or testosterone as the substrate. After 30 minutes of metabolic reaction at 37°C, the substrate-derived metabolites in the test compound-added group (4 concentrations) and the substrate-derived metabolites in the non-added group were measured by LC-MS / MS, and the inhibition rate was calculated from the ratio. In addition, the IC value was calculated from the concentration graph. 50 When a test compound is known to have an MBI effect, the IC50 is reduced by adding the substrate after pre-incubation in the presence of NADPH (cofactor) (Xenobiotica, 2009, 39(2), 99-112). 50 When the value changed by 2 times or more, it was determined that there was an MBI effect.

[1674] When the MBI effect is determined, k is calculated by nonlinear least squares method. inact (maximum enzyme inactivation rate constant) and K I (The concentration of the inhibitor that causes 50% of the maximum enzyme inactivation rate) In addition, the enzyme inactivation clearance rate (CL) was calculated according to the method described in Drug Metabolism and Disposition, 2011, 39(7), 1247-1254. int= k inact / K I (ml / min / mmol) × CYP content (pmol / mg protein)).

[1675] The IC values ​​obtained by pre-incubation were used as an indicator of the MBI effect of each example compound and prisertib on CYP3A4. 50 The fold change of the values ​​and the enzyme inactivation clearance rates are shown in the table below.

[1680] The inventors of the present application have newly discovered that prasertib inhibits CYP3A4 by MBI, and therefore carries the risk of causing serious side effects such as hepatotoxicity.

[1681] As shown in the table above, while Prestige demonstrated MBI-based CYP3A4 inhibition, the compounds of Examples 1, 2, 4, 6-8, 14, 29-31, 34, 37, and 38 did not. These results demonstrate that the compounds of Examples 1, 2, 4, 6-8, 14, 29-31, 34, 37, and 38 possess specific effects with high safety profiles, reducing not only drug interactions but also the risk of serious side effects such as hepatotoxicity. Among these, the compound represented by formula (3) exhibited particularly high safety and specific effects.

[1682] Test Example 5. Human bone marrow cell colony formation test (blood toxicity evaluation test)

[1683] Human bone marrow CD34-positive hematopoietic stem cells were obtained from LONZA Co., Ltd. The frozen cells were thawed using a medium obtained by mixing MethocultExpress medium and RPMI1640 medium containing 10% fetal bovine serum and 1% penicillin / streptomycin in a ratio of 9:1, and 5,000 cells were seeded per well in a 6-well plate and cultured overnight at 37°C and 5% CO2. The evaluation compound was added at a final concentration of 0.1% DMSO and 100 nM, and cultured for 48 hours. The cells were recovered and washed with PBS. 1 / 6 of the cells were seeded in a 12-well plate and cultured at 37°C and 5% CO2 for about 2 weeks. After the culture was completed, the number of colonies formed was calculated using thiazolyl blue tetrazolium bromide (MTT).

[1684] The representative compounds obtained in the Examples and puraseti were subjected to the test shown in Test Example 5. The results are shown in the table below.

[1685] [Table 8]

[1686]

[1687] As shown in the table above, while 100 nM of Prestige showed an inhibitory effect on human bone marrow cell colony formation, 100 nM of Example 1 did not. This result indicates that the compound of Example 1 has a specific effect on hematotoxicity and is highly safe.

[1688] Test Example 6. Liposome encapsulation test

[1689] Liposome encapsulation experiments were performed on representative example compounds and pristine.

[1690] 6.48 g of hydrogenated soybean phosphatidylcholine (COATSOME NC-21E, manufactured by NOF Corporation), 2.32 g of cholesterol (manufactured by Sigma), and 2.06 g of distearoylphosphatidylethanolamine-methoxypolyethylene glycol 2000 (SUNBRIGHT DSPE-020CN, manufactured by NOF Corporation) were dissolved in 560 mL of tert-butanol heated to 65° C. The solution was frozen in a dry ice / acetone bath, and then the tert-butanol was removed by distillation under reduced pressure to obtain a lipid mixture.

[1691] 200mL of 250mM ammonium sulfate solution was added to the above lipid mixture, heated to 65°C, and dispersed with a homogenizer (ULTRA-TURRAX, IKA company) to obtain a crude liposome dispersion. Further, the crude liposome dispersion was dispersed under a pressure of 100MPa with a high-pressure homogenizer (Nano-Mizer NM2, Yoshida Machinery Industry Co., Ltd.) to obtain liposomes with an average particle size (Z-average) of about 80nm. Using a dialysis cassette (Slide-A-Lyzer G2 Dialysis Cassettes 20KMWCO, ThermoScientific company), the extraliposome aqueous phase was replaced with a 10mM L-histidine buffer / 10% sucrose solution (pH 6.5) to obtain an empty liposome solution. The solution was filtered through a 0.22 μm membrane filter and a 10 mM L-histidine buffer / 10% sucrose solution (pH 6.5) was added to adjust the total lipid concentration to 75 mM (75 μmol / mL) or 50 mM (50 μmol / mL).

[1692] Weigh 2-3 mg of the test compound and add it to 1 mL of empty liposome solution with a total lipid concentration of 50 mM. Adjust the pH to 5.5-7 by adding 1 mol / L hydrochloric acid or 1 mol / L sodium hydroxide solution. Warm the solution in a 65°C water bath for 10-30 minutes, then cool on ice. Remove any insoluble matter by centrifugation at 15,000 × g for 5 minutes.

[1693] The liposome encapsulation rate was calculated as follows.

[1694] 100 μL of the liposome solution was passed through an ultrafiltration filter (Amicon Ultra, 100K, 0.5 mL, manufactured by Merck) and centrifuged at 15,000×g for 10 minutes at 4° C. The compound concentration in the filtrate after ultrafiltration was measured by HPLC and defined as the unencapsulated compound concentration.

[1695] The liposome solution was diluted with a trifluoroacetic acid / water / methanol mixture (0.1 / 25 / 75) and allowed to stand at 5°C for at least 10 minutes. Insoluble matter was removed by centrifugation at 15,000×g for 5 minutes, and the compound concentration in the supernatant was measured by HPLC and used as the compound concentration in the liposome solution.

[1696] The encapsulation rate and encapsulation efficiency were calculated using the following formula.

[1697] Encapsulation efficiency (%) = (compound concentration in liposome fluid - unencapsulated compound concentration) × 100 / compound concentration in liposome fluid

[1698] Encapsulation efficiency (%) = (compound concentration in liposome fluid - unencapsulated compound concentration) × 100 / compound concentration at the time of introduction

[1699] The measurement conditions of HPLC are as follows.

[1710]

[1711] It can be confirmed that Presetin, Examples 1, 3, 4, 5, and 6 can achieve a high encapsulation efficiency of 80% or more. It should be noted that in the liposome encapsulation operation of Example 4, when 1 mol / L hydrochloric acid was added to adjust the pH, a significant increase in liquid viscosity was observed. This increase in viscosity may become a problem when liposomes are produced in large quantities. On the other hand, in Examples 1, 3, 5, and 6, no increase in viscosity was found during the liposome encapsulation operation. Therefore, the compounds represented by formula (3) and (4) show particularly good liposome encapsulation operability.

[1712] Test Example 6A. Liposome encapsulation test of Example 1

[1713] For the compound of Example 1, a liposome encapsulation test was performed.

The crude liposome dispersion was further dispersed using a high-pressure homogenizer (Nano-Mizer NM2, manufactured by Yoshida Machinery Kogyo) at a pressure of 100 MPa to obtain liposomes with an average particle size (Z-average) of 80 nm. The extraliposome aqueous phase was replaced with a 10 mM L-histidine buffer / 10% sucrose solution (pH 6.5) using a dialysis cassette (Slide-A-Lyzer G2 Dialysis Cassettes 20K MWCO, manufactured by Thermo Scientific). The liposomes were then filtered through a 0.22 μm filter to obtain an empty liposome solution having a total lipid concentration of 75 mM (75 μmol / mL).

[1715] The compound of Example 1 was weighed, and approximately 0.4 mL of a 10 mM L-histidine buffer / 10% sucrose solution (pH 6.5), approximately 0.1 mL of 0.1 mol / L hydrochloric acid, and 1 mL of the above empty liposome solution were added. 1 mol / L hydrochloric acid was added to adjust the pH to 6-6.5. The mixture was heated in a 65°C water bath for 30 minutes, then ice-cooled. The mixture was then filtered through a 0.22 μm filter membrane.

[1716] The liposome encapsulation efficiency was calculated as follows.

[1744] Test Example 6B. Liposome encapsulation test of Example 1

[1745] For the compound of Example 1, a liposome encapsulation test was performed.

[1746] 11.08 g of Presome ACD-1 (a pre-mixed mixture containing hydrogenated soybean phosphatidylcholine, cholesterol, and distearoylphosphatidylethanolamine-methoxypolyethylene glycol 2000 in a mass ratio of 3:1:1, manufactured by Nippon Seika Co., Ltd.) was weighed, 200 mL of a 250 mM ammonium sulfate solution was added, and the mixture was heated to 65°C and dispersed using a homogenizer (ULTRA-TURRAX, manufactured by IKA) to obtain a crude liposome dispersion. The crude liposome dispersion was further dispersed using a high-pressure homogenizer (Nano-Mizer NM2, manufactured by Yoshida Machinery Kogyo) at a pressure of 100 MPa to obtain liposomes with an average particle size (Z-average) of 81 nm. The extraliposome aqueous phase was replaced with a 10 mM L-histidine buffer / 9.4% sucrose solution (pH 6.5) using a dialysis cassette (Slide-A-Lyzer G2 Dialysis Cassettes 20K MWCO, manufactured by Thermo Scientific) and filtered through a 0.22 μm filter to obtain an empty liposome solution having a total lipid concentration of 53.1 mg / mL.

The pH was adjusted to 6.5 with 1 mol / L hydrochloric acid or 1 mol / L sodium hydroxide. The solution was heated in a 50°C water bath for 30 minutes, then ice-cooled and filtered through a 0.22 μm filter. The concentration of the compound in the liposome solution from Example 1 was 2.00 mg / mL, the encapsulation efficiency was 98.0%, and the average particle size (Z-average) was 84 nm.

[1748] The liposome encapsulation efficiency was calculated as follows.

[1770] <Administration test>

[1771] The solution or liposome formulation was transiently administered intravenously to 7-week-old female BALB / c mice. Blood was collected from the jugular vein without anesthesia for 72 hours after administration. A 4-fold volume of methanol was added to the blood immediately after collection, and the resulting material was centrifuged. The test compound concentration in the resulting supernatant was quantified by LC-MS / MS.

[1794] [Table 17]

[1795]

[1796] According to the above results, when the encapsulated liposomes of Example 1 and Example 3 were administered intravenously, high blood retention was confirmed. This result shows that a sustained exposure of 72 hours, which is crucial for maximizing the efficacy reported in non-clinical trials of prasentia, was achieved. Therefore, Example 1 and Example 3 have excellent pharmacokinetic profiles and are extremely useful as anticancer agents. It is important that the nitrogen atom on the pyridine ring, which is a characteristic of the compound represented by formula (3), is present in a specific position.

[1797] Test Example 8. Drug efficacy evaluation test using ES-2 cell-transplanted cancer-bearing mice

[1798] Using prasertib, a liposome preparation encapsulating prasertib, and a liposome preparation encapsulating Example 1, the antitumor effect was evaluated.

[1799] The solution preparation of Presertib was prepared by dissolving Presertib in a 10 mM glycine / 5% mannitol solution (pH 2) containing 20% ​​sulfobutyl ether-β-cyclodextrin and filtering the solution through a 0.22 μm filter membrane.

[1800] The liposome preparation was prepared using the same method as in Test Example 6. The test compound was weighed, and an empty liposome solution with a total lipid concentration of 50 mM was added to make the compound concentration reach 2 mg / mL, and 1 mol / L hydrochloric acid was added to adjust the pH to 6-7. Alternatively, 10 mM L-histidine buffer / 10% sucrose solution (pH 6.5) and hydrochloric acid were added to the test compound to dissolve or disperse the compound, and an empty liposome solution with a total lipid concentration of 75 mM was added to make the compound concentration reach 2 mg / mL, and the pH was adjusted to 6-7. The liquid was heated in a 65°C water bath for 10-30 minutes and then ice-cooled. After standing in a refrigerator at 5°C for more than one night, it was filtered with a 0.22 μm filter membrane. The liposome encapsulation efficiency calculated using the method described in Test Example 6 was 99% or more.

[1801] ES-2 cells (ATCC) were intradermally transplanted into the ventral periphery of 4-7 week-old BALB / c-nu / nu mice (CAnN.Cg-Foxn1nu / CrlCrlj, female, Charles River, Japan) at a density of 1×10 6 Cells / mouse. After confirming the implantation of ES-2 cells 5 to 14 days after transplantation, the solution preparation was intravenously administered once a week at a dose of 30 mg / kg or the liposome preparation was administered at a dose of 3 mg / kg, 7.5 mg / kg, or 20 mg / kg, or subcutaneously twice a day for 3 consecutive days (a total of 6 times a week). The tumor volume was measured over time from the start of administration to evaluate the tumor volume reduction effect caused by the administration of the compound. The tumor volume was calculated by the following formula using the short diameter and long diameter of the tumor measured using an electronic vernier caliper (Mitutoyo).

[1802] Tumor volume [mm 3 ]=0.5×(minor diameter [mm]) 2 × long diameter [mm]

[1803] A control group administered with only the solvent was compared with a group administered with the compound of the present disclosure, and the anti-tumor effect was evaluated by calculating T / C using the following formula. Furthermore, the individual rates of complete tumor regression (CR) at the end of administration, resulting from administration of the solution or liposome formulation, were reported. The control group used an empty liposome solution prepared using the same method as in Test Example 6.

[1804] T / C (%) = (tumor volume of the compound of the present disclosure administration group at the end of administration - tumor volume of the compound of the present disclosure administration group at the start of administration) / (tumor volume of the control administration group at the end of administration - tumor volume of the control administration group at the start of administration) × 100

[1805] Table 18 shows each administration dose of the test compound, T / C (%) and CR individual rate in ES-2 cell-transplanted tumor-bearing mice during the administration period.

[1806] [Table 18]

[1807]

[1808] In efficacy evaluation tests using cancer-bearing mice, the liposome-formulated Example 1 demonstrated similarly superior antitumor efficacy to the liposome-formulated prasentin at all doses. In evaluation tests using a 20 mg / kg dose, these liposome formulations achieved tumor regression, which was not achieved with the solution-formulated prasentin. These test results demonstrate that Example 1 is a promising compound exhibiting superior antitumor efficacy and possesses exceptional efficacy.

[1809] Test Example 9. Measurement of Neutrophil Count in ES-2 Cell-Transplanted Cancer-Bearing Mice

[1810] ES-2 cells (ATCC) were intradermally transplanted into the ventral periphery of 4-7 week-old BALB / c-nu / nu mice (CAnN.Cg-Foxn1nu / CrlCrlj, female, Charles River, Japan) at a density of 1×10 6 cells / mouse. After confirming ES-2 cell engraftment 5-14 days after transplantation, a single intravenous administration of the liposome formulation encapsulating pristine and the liposome formulation encapsulating Example 1 was performed. Blood was collected 72 hours after administration, and the neutrophil count was measured. For comparison in this experiment, an empty liposome solution prepared using the same method as in Experimental Example 6 was used.

[1811] A control group administered with an empty liposome solution was compared with groups administered with liposome-formulated Example 1 and liposome-formulated Presertib, respectively. The neutrophil survival rate was calculated using the following formula to evaluate the safety of each preparation.

[1812] Neutrophil survival rate (%) = (neutrophil count in the administration group 72 hours after administration) / (neutrophil count in the control administration group 72 hours after administration) × 100

[1813] Table 19 shows the survival rate of neutrophils in tumor-bearing mice transplanted with ES-2 cells.

[1814] [Table 19]

[1815]

[1816] Liposomal formulation Example 1 showed the same anti-tumor effect at the same dosage as liposomal formulation of prasutamide. At 3 mg / kg, the minimum effective dose of liposomal formulation of prasutamide, the neutrophil survival rate was 15%, and anti-tumor effect and blood toxicity were observed at the same time. On the other hand, at 3 mg / kg, the minimum effective dose of liposomal formulation Example 1, the neutrophil survival rate was 61%, and the side effects of blood toxicity were reduced. In addition, as shown in Test Example 8, the liposomal formulation Example 1 also showed a higher neutrophil survival rate at the dosage of 20 mg / kg, at which tumor regression was observed, than when 7.5 mg / kg of liposomal formulation of prasutamide was administered. In summary, Example 1 is an excellent compound with both higher safety and efficacy than prasutamide, and has a special effect. In addition, the liposomal formulation of Example 1 is also an excellent compound with both high safety and efficacy, and has a special effect.

[1817] Test Example 10. Human bone marrow cell myeloid differentiation induction test (hematotoxicity evaluation test)

[1818] Human bone marrow CD34-positive hematopoietic stem cells were obtained from LONZA Co., Ltd. The frozen cells were thawed using 1% fetal bovine serum-containing IMDM culture medium, suspended using Complete hemaTox (registered trademark) myeloid culture medium, and 1,000 cells were seeded per well in a 96-well plate. The evaluation compound was added to a final concentration of DMSO of 0.1% and 3 nM, and cultured at 37°C in the presence of 5% CO2 for 7 days. After the culture was completed, half of the cell suspension in each well was recovered, and the luminescence value was measured using CellTiter-Glo (registered trademark) 3D Reagent (Promega, G968B). The cell survival rate was calculated using the following formula.

[1819] Cell survival rate (%) = (luminescence measurement value of the evaluation compound after 7 days) / (luminescence measurement value of the control group after 7 days) × 100

[1820] The representative compounds obtained in the Examples and prasetib were subjected to the test shown in Test Example 10. The results are shown in the table below.

[1821] [Table 20]

[1822]

[1823] As shown in the table above, while 3 nM of prasertib showed an inhibitory effect on myeloid cells induced by differentiation of human bone marrow cells, 3 nM of Example 1 clearly showed no inhibitory effect on myeloid cells induced by differentiation of human bone marrow cells. Based on this result, Example 1 is a compound with a high safety profile against hematotoxicity compared to prasertib, and exhibits a unique and specific effect.

[1824] Test Example 11. Tumor PD test using ES-2 cell-transplanted cancer-bearing mice

[1825] Using prasertib, a liposome formulation encapsulating prasertib, and a liposome formulation encapsulating Example 1, the pharmacodynamic (Pharmaco Dynamics: PD) response in tumors was evaluated.

[1826] The solution preparation of Presertib was prepared by dissolving Presertib in a 10 mM glycine / 5% mannitol solution (pH 2) containing 20% ​​sulfobutyl ether-β-cyclodextrin and filtering the solution through a 0.22 μm filter membrane.

[1827] The liposome preparation was prepared using the same method as in Test Example 6. The test compound was weighed, and an empty liposome solution with a total lipid concentration of 50 mM was added to make the compound concentration reach 2 mg / mL, and 1 mol / L hydrochloric acid was added to adjust the pH to 6-7. Alternatively, 10 mM L-histidine buffer / 10% sucrose solution (pH 6.5) and hydrochloric acid were added to the test compound to dissolve or disperse the compound, and an empty liposome solution with a total lipid concentration of 75 mM was added to make the compound concentration reach 2 mg / mL, and the pH was adjusted to 6-7. The liquid was heated in a 65°C water bath for 10-30 minutes and then ice-cooled. After standing in a refrigerator at 5°C for more than one night, it was filtered with a 0.22 μm filter membrane. The liposome encapsulation efficiency calculated using the method described in Test Example 6 was 99% or more.

[1828] Ovarian cancer ES-2 cells (ATCC) were transplanted intradermally around the ventral part of 4-7 week-old BALB / c-nu / nu mice (CAnN.Cg-Foxn1nu / CrlCrlj, female, Charles River, Japan) at a density of 1×10 6Cells / mouse. After confirming the engraftment of ES-2 cells 5 to 14 days after transplantation, each experiment was administered under the following conditions:

[1829] Test A: A single intravenous dose of 30 mg / kg of a solution formulation or 7.5 mg / kg, 3 mg / kg, 1 mg / kg, or 0.3 mg / kg of a liposome formulation was administered. Test B: A single intravenous dose of 30 mg / kg of a solution formulation or 7.5 mg / kg, 3 mg / kg, 1 mg / kg, or 0.3 mg / kg of a liposome formulation was administered. Test C: A single intravenous dose of 20 mg / kg, 7.5 mg / kg, 3 mg / kg, 1 mg / kg, or 0.3 mg / kg of a liposome formulation was administered. Tumors were recovered 1, 3, or 6 days after administration, and the PD response of the tumors based on compound administration was evaluated.

[1830] The PD response in tumors was evaluated by Western blotting. The intensity of each band detected by anti-γH2AX antibody (05-636, Merck) and anti-tubulin antibody (3873, Cell Signaling Technology) was calculated using ImageJ software.

[1831] The control group administered with the solvent alone was compared with the compound-administered group, and the relative value of each band intensity was calculated using the following formula to evaluate the PD response in the tumor.

[1832] Intensity of γH2AX={(band intensity of γH2AX in the tumor of the compound-administered group of the present invention) / (band intensity of tubulin in the tumor of the compound-administered group of the present invention)} / {(band intensity of γH2AX in the tumor of the control-administered group / band intensity of tubulin in the tumor of the control-administered group)}×100

[1833] Figure 7-9 The intensity of γH2AX in ES-2 cancer-bearing mice transplanted with cells is shown at each administration dose of the test compound and during the administration period.

[1834] According to the above results, as shown in Test Example 11 Test A, when liposome-formulated prasutamide was administered, a strong PD response effect at a dose of 7.5 mg / kg was confirmed 3 days after administration, achieving a PD response effect that could not be achieved with solution-formulated prasutamide. As shown in Test Example 11 Test B, when liposome-formulated Example 1 was administered, a strong PD response effect at a dose of 7.5 mg / kg was confirmed 1 day after administration, achieving a PD response effect that could not be achieved with solution-formulated prasutamide. As shown in Test Example 11 Test C, when liposome-formulated Example 1 was administered, a strong PD response effect at doses of 7.5 mg / kg and 20 mg / kg was confirmed 3 days after administration and 6 days after administration. These liposome formulations, as shown in Test Example 7, achieved the 72-hour sustained exposure that was reported in non-clinical trials of prasutamide, which is crucial for maximizing drug efficacy. Therefore, Example 1 has excellent pharmacokinetic and pharmacodynamic profiles and is extremely useful as an anticancer agent.
