Description

Crystal polymorphs of aminopyrimidine derivatives and methods for preparing the same

[0001] The present application relates to a crystal polymorph of an aminopyrimidine derivative and a method for producing the same.

[0002] The aryl hydrocarbon receptor (AhR) is widely known as a crucial intracellular chemical sensor that responds to various natural and artificial environmental compounds. This receptor plays a key role in various diseases, including autoimmunity, infection, and cancer, and is particularly important in cancer cell proliferation, tissue invasion, metastasis, and angiogenesis. Furthermore, AhR is closely associated with autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and multiple sclerosis (MS). Therefore, the development of AhR-targeted therapies could offer a potential opportunity to overcome immune-related diseases. These findings suggest that the development of therapeutics targeting AhR could offer a new potential opportunity to overcome immune-related diseases.

[0003] The present application provides a novel polymorph of an aminopyrimidine derivative capable of modulating the AhR pathway, and a method for preparing the same. The novel polymorph according to one example of the present application exhibits improved stability compared to existing forms, and is expected to provide a more effective treatment option.

Treatment of cancer includes inhibiting cancer growth (including causing partial or complete regression of the cancer), inhibiting cancer progression or metastasis, preventing cancer recurrence or residual disease, and / or prolonging the survival of a patient. A "therapeutically effective amount" is an amount of a drug that can achieve the desired therapeutic, palliative, or preventative effect for the condition being treated.

[0108]

[0109] Effective amount

[0110] In some embodiments, the effective dose range of a compound may be determined by measuring the patient's blood compound concentration under a specific dosing regimen to establish a concentration-time profile, consulting the established correlation between the concentration-time profile obtained during the trial and the tumor inhibition or elimination, and further considering the patient's health status or physical endurance, thereby balancing the achievable therapeutic effect with the potential for toxicity to the patient. The frequency of compound administration may be determined similarly. The administration may continue until the patient is cancer-free.

[0111] In some embodiments, the effective dose for tumor treatment may be determined by the patient's ability to stabilize disease progression and / or improve symptoms, and preferably reverse disease progression (e.g., by reducing tumor size). In some embodiments, a maintenance dose may be administered to ensure complete removal or eradication of the cancer, or prevention of residual disease, once the patient is cancer-free. The duration of maintenance administration may be determined based on clinical trial data.

[0112] In some embodiments, the compound may be administered in combination with one or more other cancer therapeutics that target AhR or molecules other than AhR. The compound may be formulated separately or together with the other cancer therapeutics. The compound may be administered on the same or a different schedule as the other cancer therapeutics. The ratio of the compound to the other cancer therapeutics may be determined through clinical trials. Combining the compound with the other cancer therapeutics may further enhance the efficacy of each other. For example, the compound of the present application may be administered with an immune checkpoint inhibitor, such as an inhibitor of PD-1, PD-L1, or PD-L2 (e.g., pembrolizumab, nivolumab, or atezolizumab), or with CAR-T therapy (e.g., axicabtagene ciloleucel), to achieve additive or synergistic anticancer effects.

[0113] Dosage regimens may be adjusted to provide the optimal desired response. The dosage unit form used herein refers to physically discrete units suited as single dosages for the patients / subjects to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier.

[0114] It should be noted that dosage values ​​may vary depending on the type and severity of the condition to be alleviated and may include single or multiple doses. For any particular subject, a specific dosage regimen should be adjusted over time according to the individual's needs and the professional judgment of the person administering or supervising the administration of the composition. It should be further understood that the dosage ranges described herein are exemplary and are not intended to limit the scope or practice of the compositions embodied. Furthermore, dosage regimens using the compositions of the present application may be based on various variables, including the type of disease, age, weight, sex, the patient's medical condition, the severity of the condition, the route of administration, and the specific antibody used. Therefore, dosage regimens may vary widely but can be routinely determined using standard methods. For example, dosages may be adjusted based on pharmacokinetic or pharmacodynamic parameters, which may include clinical effects such as toxicity and / or experimental values.

[0115] Suitable dosages of the compounds of the present invention are considered to be 0.001-200 mg / kg per day, preferably about 0.01 mg / kg to about 20 mg / kg per day, such as about 0.5-50 mg / kg, for example about 1-20 mg / kg. The compounds may be administered, for example, at least 0.25 mg / kg, such as at least 0.5 mg / kg, such as at least 1 mg / kg, such as at least 1.5 mg / kg, such as at least 2 mg / kg, such as at least 3 mg / kg, such as at least 4 mg / kg, such as at least 5 mg / kg; and, for example, at most 50 mg / kg, such as at most 30 mg / kg, such as at most 20 mg / kg, such as at most 15 mg / kg. Dosages are usually repeated at appropriate intervals, for example, twice daily, three times daily, once daily, once weekly, once every two weeks, or once every three weeks, for as long as the attending physician deems appropriate, and the attending physician may optionally increase or decrease the dosage as necessary.

[0116] The compounds of the present invention can be used in particular for the treatment and prevention, i.e. prophylaxis, of tumor growth and metastasis, and in particular for solid tumors of all indications and stages, regardless of prior treatment of tumor growth.

[0117] Some embodiments of these methods may further comprise administering or treating with one or more additional anticancer therapies. In some of these embodiments, the additional anticancer therapies include surgery, radiation therapy, biotherapy, immunotherapy, chemotherapy, or any combination thereof.

[0118] Some embodiments of these methods may further comprise administration or treatment with one or more anticancer agents. In some of these embodiments, the anticancer agents are chemotherapeutic agents, growth inhibitors, antiangiogenic agents, cytotoxic agents, antihormonal agents, prodrugs, or cytokines.

[0119] In a further embodiment of the present application, the crystalline form according to an example of the present application can be used to sensitize cells to radiation, i.e., treating cells with a compound of the present application prior to radiation treatment of the cells renders them more sensitive to DNA damage and cell death than cells not treated with any of the crystalline forms according to an example of the present application. In one aspect, the cells are treated with one or more compounds of the crystalline form according to an example of the present application.

[0120] Accordingly, the present application also provides a method of killing cells, wherein one or more crystal forms of the present application are administered to the cells in combination with conventional radiation therapy.

[0121] The present application also provides a method for making a cell more susceptible to apoptosis, wherein the cell is treated with one or more crystal forms of the present application prior to treatment to cause or induce apoptosis. In one aspect, after the cell is treated with one or more crystal forms of the present application, the cell is treated with at least one compound, at least one method, or a combination thereof to induce DNA damage with the aim of inhibiting normal cell function or causing cell death.

[0122] In another embodiment of the present application, the cell is treated with at least one DNA damaging agent to cause apoptosis, i.e., the cell is treated with one or more crystal forms of the present application to sensitize the cell to apoptosis, and then the cell is treated with at least one DNA damaging agent to cause the cell to die. DNA damaging agents useful in the present application include, but are not limited to, chemotherapeutic agents (e.g., cisplatin), ionizing radiation (e.g., X-rays, ultraviolet radiation), carcinogens, and mutagens.

[0123] In another embodiment, the cell is killed by treating the cell with at least one method that causes or induces DNA damage. Such methods include, but are not limited to, activating a cellular signaling pathway that causes DNA damage when activated, inhibiting a cellular signaling pathway that causes DNA damage when inhibited, and inducing biochemical changes in the cell that cause DNA damage. As a non-limiting example, inhibition of a cellular DNA repair pathway may inhibit the repair of DNA damage and lead to an abnormal accumulation of DNA damage in the cell.

[0124] In one aspect of the present application, the crystalline form of the present application is administered to a cell prior to radiation or other induction of DNA damage in the cell. In another aspect of the present application, the crystalline form of the present application is administered to a cell concomitantly with radiation or other induction of DNA damage in the cell. In another aspect of the present application, the crystalline form of the present application is administered to a cell immediately after radiation or other induction of DNA damage in the cell begins.

[0125] In another aspect, the cells are in vitro. In another embodiment, the cells are in vivo. The crystalline form of the present application can be administered as a single agent or in combination with one or more other pharmaceutically active ingredients, provided that the combination does not cause unacceptable side effects.

[0127] The crystalline form of the present invention may be further combined with other drugs that target the immune system, such as immune checkpoint inhibitors, for example, aPD-1 / -L1 axis antagonists.

[0128] PD-1, along with its ligands PD-L1 and PD-L2, functions as a negative regulator of T cell activation. AHR suppresses immune cell function while increasing cancer cell proliferation and motility. PD-L1 is overexpressed in many cancers, and PD-1 overexpression often occurs concurrently in tumor-infiltrating T cells. Consequently, T cell activation is weakened, immune surveillance is evaded, and anti-tumor immune responses are impaired.

[0129] Simultaneous targeting of the PD-1 / -L1 axis and AHR enhances anti-tumor immune responses beyond additive, leading to unexpected tumor growth reduction.

[0130] Therefore, a composition comprising a PD-1 / -L1 axis antagonist and an AHR antagonist is surprisingly effective in enhancing immune responses and treating cancer.

[0131] Additionally, the crystalline form of the present invention can also be used as a therapeutic agent for various other disorders involving AHR.

[0132] Examples of other disorders associated with abnormal AhR signaling inflammation may be one or more selected from the group consisting of infections and cancer vaccinations, viral infections, obesity and diet-induced obesity, adiposity, metabolic disorders, hepatic steatosis and uterine fibroids (uterine leiomyomas or uterine fibroids) in women, chronic kidney disease, acute and chronic renal failure, diabetes, inflammatory or hypertensive kidney disease, heart failure, angina pectoris, hypertension, pulmonary hypertension, ischemia, vascular disease, thromboembolism, arteriosclerosis, sickle cell anemia, erectile dysfunction, benign prostatic hyperplasia, urinary retention disorders associated with benign prostatic hyperplasia, Huntington's, dementia, Alzheimer's and Creutzfeldt-Jakob.

[0133] Also, in another aspect, a pharmaceutical composition is provided, comprising an AhR modulator, such as a crystalline form according to one example of the present application, and a pharmaceutically acceptable excipient.

[0134] In some aspects, pharmaceutical compositions comprising an AhR modulator, such as an AhR antagonist in crystalline form according to one example of the present application, are provided for use in modulating constitutive AhR activity in a subject in need thereof.

[0135] In some aspects, pharmaceutical compositions comprising an AhR modulator, such as an AhR antagonist in crystalline form according to one example of the present application, are provided for use in treating cancer or a cancer condition by modulating AhR activity.

[0136] In some aspects, pharmaceutical compositions comprising an AhR modulator, such as an AhR antagonist in crystalline form according to one example of the present application, are provided for use in inhibiting cancer cell proliferation, tissue invasion, metastasis, and angiogenesis in a subject having cancer, a cancer condition, or a tumor.

[0137]

[0138] aryl hydrocarbon receptor

[0139] The aryl hydrocarbon receptor ("AhR") is a ligand-dependent member of the family of basic-helix-loop-helix transcription factors that has been shown to be activated by a variety of structurally diverse synthetic and naturally occurring compounds, such as polycyclic aromatic hydrocarbons, indoles, and flavonoids. In the absence of bound ligand, AhR resides in a latent state in the cytoplasmic compartment of cells, where it associates with two molecular chaperones, heat shock protein 90 ("hsp90"), an immunophilin-like protein, XAP2, and the hsp90-interacting protein, p23.

[0140] The term "aryl hydrocarbon receptor" or "AhR," as used herein, refers to an 848 amino acid polypeptide, as described, for example, in NP_001612, together with any naturally occurring alleles, splice variants, and engineered forms thereof. Generally, AhR refers to human AhR. The term AhR is also used to refer to truncated forms or fragments of an AhR polypeptide, for example, comprising a specific AhR domain. References to such forms of AhR may be identified herein as "AhR (122-224)".

[0141]

[0142] AhR modulators

[0143] AhR mediates a variety of functional responses, including but not limited to, de novo transcription of AhR battery genes or target genes bearing the DRE or XRE responsive element 5'-TNGCGTG-3'. Alternative pathways of AhR signaling have also been described, such as binding to the retinoblastoma protein, estrogen receptor (ER), transcription factor E2F1, and NFκB pathway subunits RelA and RelB. AhR can also act as a ubiquitin ligase. Thus, signaling through AhR encompasses multiple pathways, including constitutive and non-constitutive AhR signaling pathways or signaling activities, as such terms are defined herein.

[0144] As used herein, “constitutive AhR signaling” refers to one or more signaling pathways that are mediated or regulated by AhR, activated or driven by one or more endogenous AhR ligands, or one or more environmental ligands such as toxins or pollutants, and that result in constitutive or long-term translocation of AhR to the nucleus, and activation or regulation of one or more AhR battery genes involved in unregulated cell growth and proliferation, tumor cell invasiveness, or a combination thereof.

[0145] As used herein, "non-constitutive AhR signaling" refers to one or more signaling pathways mediated or induced by AhR that do not result in constitutive or long-term translocation of AhR to the nucleus, and do not result in activation or regulation of one or more AhR battery genes involved in unregulated cell growth, tumor cell invasiveness, or a combination thereof. In some embodiments, non-constitutive AhR signaling does not result in upregulation of CYP1A1, CYP1B1, or a combination thereof gene expression.

[0146] Accordingly, the term "AhR modulator" as used herein refers to an agent, such as a crystalline form of a compound of Formula 1, a solvate, or a hydrate thereof, that modulates, induces, or promotes a qualitative or quantitative change, alteration, or modification in one or more processes, mechanisms, effects, responses, functions, activities, or pathways mediated by the AhR receptor. Such changes mediated by AhR modulators, such as the AhR antagonists described herein, may mean a reduction, inhibition, or conversion of the constitutive activity of the AhR. The term "expression" refers to the cellular processes involved in producing RNA and proteins, including, but not limited to, secreting proteins, and, where appropriate, transcription, translation, folding, modification, and processing, as applicable. "Expression products" include RNA transcribed from a gene and polypeptides obtained by translation of mRNA transcribed from a gene.

[0147] The term "modulate" in relation to AhR modulators is used consistently with its usage in the art to mean, for example, causing or enabling a qualitative or quantitative change, alteration, or modification in one or more biological processes, mechanisms, effects, responses, functions, activities, pathways, or other phenomena of interest. Thus, as used herein, modulation refers to a qualitative or quantitative change, alteration, or modification in one or more processes, mechanisms, effects, responses, functions, activities, or pathways mediated by the AhR receptor.

[0148] The term "agent" as used herein in connection with an AhR modulator means any compound or substance, such as, but not limited to, a small molecule compound, a nucleic acid, a polypeptide, a peptide, a drug, an ion, and the like. An "agent" can be any chemical, entity, or moiety, and includes, without limitation, synthetic and naturally occurring proteinaceous and non-proteinaceous materials. In some embodiments, the agent is a nucleic acid, a nucleic acid analog, a protein, an antibody, a peptide, an aptamer, an oligomer of a nucleic acid, an amino acid, or a carbohydrate, and includes, without limitation, proteins, oligonucleotides, ribozymes, DNAzymes, glycoproteins, siRNAs, lipoproteins, aptamers, and modifications and combinations thereof. In certain embodiments, as described herein, the agent is a small molecule having a chemical moiety. For example, the chemical moiety comprises an unsubstituted or substituted alkyl, aromatic, or heterocyclyl moiety. Compounds may be known to have the desired activity and / or property (e.g., modulating AhR activity) or may be selected from a library of diverse compounds, for example, using the screening methods described herein.

[0149] In some embodiments, an AhR modulator selectively binds to AhR. As used herein, "selectively binds" or "specifically binds" refers to the ability of an AhR antagonist to bind to a target, such as AhR. D  10 -5  M (10000 nM) or less, for example, 10 -6  M and below, 10 -7  M and below, 10 -8  M and below, 10 -9  M and below, 10 -10  M and below, 10 -11  M or less, or 10 -12  It binds to less than M. For example, the antagonist described herein is 10 -5K below M D An agent binds specifically to AhR if it binds to AhR but not to other molecules or related homologues. Specific binding can be influenced by, for example, the affinity and avidity of the antagonist, and the concentration of the antagonist used. One skilled in the art can determine appropriate conditions under which an antagonist described herein selectively binds using any suitable method, such as those described herein (e.g., titration of an AhR antagonist in an appropriate cell binding assay).

[0150] In some aspects of the compositions and methods described herein, the AhR modulator is an AhR antagonist having a crystalline form described herein.

[0151] As used herein, an AhR modulator is an "AhR antagonist." An AhR antagonist refers to an AhR inhibitor that, when specifically bound to the AhR, does not induce a biological response itself, but blocks or attenuates an agonist- or ligand-mediated response. That is, an AhR antagonist can bind to the AhR but does not activate the AhR; the binding interferes with the interaction, displaces the AhR agonist, and / or inhibits the function of the AhR agonist. Therefore, as used herein, an AhR antagonist does not function as an inducer of AhR activity when bound to the AhR; that is, they function as pure AhR inhibitors. In some embodiments, an AhR antagonist selectively binds to the AhR.

[0152] In some embodiments of these aspects, the AhR antagonists described herein, such as the crystalline forms according to one embodiment of the present application, block constitutive AhR effector function that mediates the growth and progression of established tumors. In other embodiments, the small molecule AhR antagonists described herein, in crystalline form, act as chemopreventive agents by blocking AhR-mediated CYP1A1 induction and mutagenesis upon exposure to environmental ligands.

[0153] In some embodiments of these aspects, the crystalline form of the AhR antagonist described herein inhibits the initial contribution of constitutively active AhR in inducing malignant transformation. In some embodiments, the crystalline form of the compound described herein inhibits constitutive AhR signaling-mediated cancer or tumor cell growth. In some embodiments, the crystalline form of the compound described herein inhibits constitutive AhR signaling-mediated tumor invasion in inducing malignant transformation.

[0154] The novel crystalline form according to an example of the present application has excellent storage stability and can be usefully used as an AhR modulator compound.

[0214] Test Example 1. Evaluation of AhR inhibition efficacy

[0215] AhR activation induces target gene expression, such as CYP1A1 and CYP1B1, by binding to AhR-responsive DNA elements, also known as XREs (xenobiotics responsive elements). The assay used to measure AhR activity here is a luciferase assay using cell lines transfected with a luciferase reporter plasmid containing an XRE upstream of a reporter gene. Cells transfected with the XRE-luciferase reporter (XRE-Luc) plasmid drive luciferase activity, which reflects activation and inhibition of AhR in the cells. In addition to transfection with the XRE-reporter vector, cells were co-transfected with a nano-luciferase reporter gene construct (Nano-Luc) containing a constitutively active promoter as an internal control. Kynurenine and kynurenic acid (endogenous AhR agonists) were used to stimulate cells to test the antagonistic properties of the compounds. The half-maximal inhibitory concentration (IC50) and half-maximal effective concentration (EC50) values ​​were calculated using nonlinear regression (four parameters) with Prism8.0 software (GraphPad).

[0217] (1) In vitro assay 1: Antagonism in human cell lines

[0218] HepG2 (human hepatoma cell line) cells (Invivogen) stably harboring XRE-luciferase reporter were plated in complete medium and cultured at 37°C in a CO2 incubator. After 24 h, cells were treated with kynurenine (200 μM) alone (negative control) or together with test compounds for 6 h. Luciferase activity was measured using commercial kits such as Promega Luciferase kit or Invivogen Luciferase kit. IC50 values ​​were calculated using luciferase activities. Luciferase activities were further normalized to the kynurenine alone group as the maximum control group and the vehicle group as the minimum control group. The AhR antagonistic potency of compounds in Preparation Example 1 is shown in Table 9. (IC 50 The values ​​are grouped into A, B, C and D, where A: IC 50 < 0.01 μM; B: 0.01 < IC 50 < 0.1 μM; C: 0.1 < IC 50 < 1.0 μM; D: IC 50 >1.0μM)

[0221] Hepa1c1c7 (murine hepatoma cell line) cells co-transfected with XRE-Luc and Nano-Luc plasmids were plated in complete medium and cultured overnight at 37°C in a CO2 incubator. After incubation, cells were treated with AhR-activating ligands such as kynurenic acid and kynurenine (#) with or without test compounds for 6 h. Firefly luciferase and Nano-luciferase activities were measured using Nano-glo Luciferase kit (Promega) and relative luciferase activities (Firefly / Nano-Luc) were expressed as IC 50The values ​​were calculated. The relative luciferase activities were further normalized to the agent-only group as the maximum control and the vehicle group as the minimum control. The AhR antagonistic potency of compounds of Preparation Example 1 is shown in Table 9. (IC50 values ​​are grouped into A, B, C and D, where A: IC 50 < 0.01 μM; B: 0.01 < IC 50 < 0.1 μM; C: 0.1 < IC 50 < 1.0 μM; D: IC 50 > 1.0μM)

Then, 1% of 0.1 mM DMSO stock of compound of Example 1 was added and incubated at a concentration of 1 uM. After 60 minutes of addition of the compound, the reaction was terminated by adding an organic solvent, and the mixture was centrifuged and quantitatively analyzed using LC-MS / MS.
