Abstract
Description
[Technical Field]
[0001] This disclosure relates to novel substituted 2-phenylpiperidine compounds, methods for preparing them, and their use in the diagnosis, treatment, and / or prevention of cancer. In particular, this disclosure relates to novel substituted 2-phenylpiperidine compounds, methods for preparing them, and their use in the diagnosis, treatment, and / or prevention of neuroblastoma. [Background technology]
[0002] Cancer is a general term for a large group of diseases that can affect any part of the body. One defining characteristic of cancer is the rapid formation of abnormal cells that grow beyond normal boundaries, which can invade adjacent parts of the body and spread to other organs; the latter process is called metastasis. Extensive metastasis is the leading cause of death from cancer.
[0003] Approximately one in six deaths worldwide is caused by cancer. Currently, it is the second leading cause of death globally, as well as in countries with high and very high Human Development Indices (HPDs), after cardiovascular disease. By 2040, the global burden is estimated to increase to 27.5 million new cancer cases and 16.3 million cancer deaths annually due to population growth and aging.
[0004] G protein-coupled receptors (GPCRs) belong to the largest superfamily of endogenous cell membrane proteins and play diverse roles in cellular signaling. The neurokinin 1 receptor (commonly abbreviated as NK1R, also known as the tachykinin 1 receptor) belongs to the tachykinin receptor subfamily of GPCRs. Two isoforms of NK1R have been reported: a truncated form containing a very short C-terminal sequence (311 amino acids) and a full-length sequence (407 amino acids).
[0005] Peptide substance P (SP), which is widely distributed in both the central and peripheral nervous systems, triggers various functions after binding to NK1R. Antagonists of NK1R are known to have anti-inflammatory, analgesic, anxiolytic, antidepressant, and antiemetic effects.
[0006] The SP / NK1R system has been found to strongly influence the tumor microenvironment and may be involved in carcinogenesis-related processes such as mitosis induction, angiogenesis, cell migration, and metastasis. NK1R levels typically show limited peripheral expression in normal tissues but have been shown to be upregulated in several cancer types. Subsequently, SP has been demonstrated to act as a mitogenic factor through NK1R in several human cancer cell lines, including astrocytoma, melanoma, prostate, glioma, retinoblastoma, leukemia, and pancreatic, laryngeal, colon, gastric, and breast cancer.
[0007] NK1R inhibitors have demonstrated cancer growth inhibition in numerous in vitro and in vivo models. As a result, the NK1R / SP system is considered a promising target for cancer diagnosis and therapy, including the concept of selectively imaging and targeting tumor cells that overexpress NK1R.
[0008] NK1R is highly expressed in neuroblastoma (NBL), the most common extracranial solid tumor in children. NBL tumors are characterized by remarkable biological heterogeneity. Some tumors exhibit highly invasive and therapy-resistant behavior, while others spontaneously regress. To account for this diversity, current treatment strategies are uniquely guided by pretreatment risk stratification based on a wide range of clinical, histological, molecular, and biological markers. Thus, the prognosis and treatment of NBL are highly dependent on molecular, genetic, and pathological examinations.
[0009] Following risk stratification, NBL treatment approaches range from observation or resection of tumors considered low-risk to intensive multimodal therapy for high-risk tumors, including induction chemotherapy (administered at the start of cancer treatment), surgery, radiation, consolidation therapy (administered after initial treatment targeting residual cancer cells), and immunotherapy.
[0010] Current treatments are not entirely effective, and NBL remains a major therapeutic challenge in pediatric oncology. While multimodal therapy can often dramatically reduce tumor burden and lead to apparent complete remission of the disease (referred to as minimal residual disease), patients diagnosed with high-risk tumors have a survival rate of only 40–50%, suffer from frequent and long-lasting side effects, and approximately 50% of patients who complete treatment experience disease recurrence.
[0011] Radiopharmaceuticals are medicines containing radioisotopes that are designed to target specific cells, organs, or tissues and are increasingly being used for both the diagnosis and treatment of numerous cancers.
[0012] Radiopharmaceuticals are administered systemically and, unlike conventional therapies (e.g., radiation therapy, chemotherapy, surgery), bind to specific transmembrane proteins of cancer cells to precisely achieve the desired imaging or therapeutic effect.
[0013] Radiopharmaceuticals are often developed in "theranostic" pairs, consisting of diagnostic and therapeutic compounds. Diagnostic compounds are designed with radioisotopes that enable imaging, such as positron emission tomography (PET) imaging, while therapeutic compounds are designed with radioisotopes that enable radiotherapy. Using these complementary theranostic pairs, clinicians can assess patient response before treatment and tailor subsequent radiotherapy doses to individual patients.
[0014] Aprepitant (commercially known as EMEND, also known as L-754,030) is an NK1R antagonist primarily used to treat chemotherapy-induced nausea and vomiting and has been shown to exhibit antitumor effects. However, aprepitant's poor pharmacokinetic profile, including low solubility and poor metabolic stability, impairs its antitumor potential. Furthermore, aprepitant crosses the blood-brain barrier (BBB) and thus carries an increased risk of central nervous system (CNS) related side effects. Radiohalogenation of aprepitant has not been demonstrated. Instead, it is conjugated with the chelate DOTA (dodecanetetraacetic acid) for radiometallic labeling. The residual properties of the DOTA-chelated radiolabeled molecule mediate high renal dose and dose-limiting toxicity. [ka]
[0015] Halik P. et al., Pharmaceutics 2022, 14, 607, is functionalized with a DOTA chelating agent. 68 Ga and 177 We disclose that three novel Lu-labeled aprepitant homologs showed higher affinity and better binding ability to the human NK1 receptor in receptor binding studies than SP derivatives currently used in glioblastoma therapy. This confirmed assumption regarding the usefulness of aprepitant as an NK1R-targeting vector is stated. Furthermore, several reports state that they offer new perspectives on the use of aprepitant and other NK1R antagonists as vectors for selective radiopharmaceuticals for NK1R-positive tumors.
[0016] L-733,060 is an antagonist for NK1R that has shown anticancer effects in many in vitro models. Kowaluk,EA; Arneric,SP, Annual Reports in Medicinal Chemistry 1998,33,11-20 reported that it overcomes the bioavailability problems often associated with neurokinin antagonists and can cross the blood-brain barrier. [ka]
[0017] Tattersall FD et al., Neuropharmacology 1996, 35, 1121-1129, disclose the pharmacological profile of L-741,671, a non-peptide human neurokinin 1 (hNK1) receptor selective antagonist, which has been shown to be cerebral permeable. Cerebral permeability has been described as essential for the antiemetic effect of systemically administered NK1 receptor antagonists. [ka]
[0018] WO 93 / 04040 A1, WO 94 / 19323 A1, and WO 95 / 20575 A1 disclose a class of azacyclic compounds useful as tachykinin (NK1-receptor) antagonists. The compounds disclosed in WO 93 / 04040 A1 and WO 94 / 19323 A1 comprise azacyclic ring systems substituted with arylmethyloxy or arylmethylthio moieties, while the compounds disclosed in WO 95 / 20575 A1 comprise azacyclic ring systems substituted with aralkylamino moieties. Furthermore, the compounds disclosed in WO 94 / 19323 A1 and WO 95 / 20575 A1 are stated to be used for the treatment of pain, inflammation, migraines, and vomiting.
[0019] WO 95 / 23798A1 discloses a substituted heterocycle, a tachykinin receptor antagonist useful in the treatment of inflammatory diseases, pain or migraines, asthma, and vomiting.
[0020] Munoz M. et al., Neuropeptides 2005, 29, 245-254, disclose an in vitro study to investigate the ability of the NK1 receptor antagonist L-733,060 to inhibit cell growth in the SKN-BE(2) neuroblastoma cell line. The study shows that micromolar concentrations of L-733,060 are effective in inhibiting cell line growth. The presence of the NK1 receptor is demonstrated in the tested cell line, thus demonstrating that the antitumor effect of L-733,060 is mediated through the NK1 receptor. The NK1 receptor is suggested to be a novel and promising target in the treatment of human neuroblastoma.
[0021] Rosso M. et al., Tumor Biology 2008, 29, 245-254, disclose an in vitro study of the growth inhibitory ability of L-733,060 against human gastric and colonic adenocarcinoma. The study shows that micromolar concentrations of L-733,060 are effective in inhibiting the growth of such cell lines. The presence of several NK-1 receptor isoforms has been observed in human gastric and colonic adenocarcinoma, thus demonstrating that the antitumor effect of L-733,060 against both human cell lines is mediated through the NK-1 receptor. The NK-1 receptor is suggested to be a novel and promising target in the treatment of human gastric and colonic adenocarcinoma.
[0022] Any listing or discussion of documents that are clearly previously published in this specification should not necessarily be considered an acknowledgment that such documents are part of the latest technology or common knowledge.
[0023] A drawback of current cancer therapies is the management of a limited number of cells that evade induction and consolidation therapy. These cells are capable of proliferation and / or migration, leading to metastatic recurrence. Targeted theranostic radiopharmaceuticals, when administered during induction and consolidation therapy, particularly during the minimal residual disease (RAM) phase, can have a significant impact on survival rates.
[0024] Therefore, there is a need for compounds for use in the diagnosis, treatment, and / or prevention of cancer. Furthermore, there is a need for compounds for use in the diagnosis, treatment, and / or prevention of neuroblastoma. [Overview of the Initiative]

[0080] Unexpectedly, the compounds of the present disclosure have been found to bind to NK1R, i.e., neurokinin 1 receptor, which is associated with and overexpressed in many cancers such as neuroblastoma. Thus, the presence of the large iodine atom in the compounds does not prevent interaction with NK1R. This is an important advantage as iodine can be provided as different isotopes in the compounds, thereby enabling different therapeutic uses. For example, some isotopes can be used for diagnosis, including diagnosis such as diagnostic imaging, and other isotopes can be used in combination with therapy. Thus, the same compound can be labeled with different isotopes depending on the desired use to provide a theranostic pair consisting of a diagnostic and a therapeutic compound.
[0081] Furthermore, the compounds of the present disclosure have been found to specifically bind to NK1R. This is important to ensure specific accumulation of the compound at the intended therapeutic site(s) and to avoid non-specific uptake in healthy tissues / organs (i.e., tissues and / or organs not intended to be targeted by the therapy) so that associated side effects are minimized.

[0083] A pharmaceutical composition may be a pharmaceutical composition for intravenous administration. For example, a pharmaceutical composition for intravenous administration may be a solution, such as an aqueous solution, containing a compound of formula I or a pharmaceutically acceptable salt thereof.
[0084] In a further example, the pharmaceutical composition may be an oral pharmaceutical composition. In particular, the oral pharmaceutical composition may contain a compound of formula I, where Y is 127 I or 125 It contains or consists of I. For example, an oral pharmaceutical composition may be provided as a liquid, such as a syrup, suspension, or solution. Alternatively, an oral pharmaceutical composition may be provided as a solid, such as a tablet, capsule, or lozenge.
[0085] Furthermore, compounds of formula I described herein, or pharmaceutically acceptable salts thereof, or pharmaceutical compositions are provided for use as pharmaceuticals in therapy.

[0181] biology Binding affinity measurement NB cell line The binding characteristics of the compound from Example 4 in different human NB cell lines, SK-N-AS, and IMR-32 were evaluated using LigandTracer Grey (Ridgeview Instruments, Uppsala, Sweden).
[0182] Total 3 x 10 5Individual cells (IMR-32) or 2.5 × 10⁶ 5 Cells (SK-N-AS) were seeded on polydopamine-coated petri dishes according to the manufacturer's instructions (Ridgeview Instruments, Uppsala, Sweden) to allow cell adhesion, and incubated at 37°C for 24 hours. A baseline curve was then obtained by adding CO2-bound medium (3 mL, ibco / Thermo Fisher, Waltham, MA, USA) to the petri dish and running LigandTracer for 10 minutes. The compound from Example 4 (300 nM in fresh supplemental cell medium, ≥95% radiolabeling yield) was then added, and LigandTracer was run for 3-4 hours. A further 700 nM of the compound from Example 4 was added to the cell solution to obtain a final concentration of 1 μM. After running LigandTracer for 3-4 hours, the cell medium was removed and replaced with 3 mL of fresh medium, and the assay was run overnight to establish the dissociation curve. The resulting coupling curves were evaluated for different dynamic interaction models (1:1 and 1:2) using TraceDrawer 1.9 software (Ridgeview Instruments, Uppsala, Sweden).

The solid lines represent the calculated fit. The recorded curves can be seen as being close to a 1:2 fit, indicating a 1:2 kinetic fit. Figure 4 shows the real-time binding curves of the compounds from Example 4 in human NB cell lines SK-N-AS and IMR-32. The highest signals were observed for IMR-32, followed by SK-N-AS.

Low nanomolar K of the compound in Example 4 1:2 kinetic model analysis D1 The values and combined real-time binding curves show that the binding affinity of the compound in Example 4 is large. 125 This demonstrates that the material is not altered by the attachment of an I atom.
[0187] Colorectal cell line HT-55 The binding characteristics of the compound in Example 4 in a human HT-55 colorectal cancer cell line expressing the NK1 receptor were evaluated according to the same procedure outlined above.
[0188] 1.5 × 10 6HT-55 cells were seeded on a gradient cell culture Nunc dish (catalog number 150350, Thermo Fisher Scientific) and incubated at 37°C in an atmosphere containing 5% CO2. After 48 hours of incubation, real-time binding measurements were performed. The cell medium was switched to 3 ml of fresh medium before the start of the binding measurements. Binding of the compound of Example 4 to HT-55 cells was measured at room temperature using a LigandTracer Grey (Ridgeview Instruments AB, Uppsala, Sweden). After collecting the baseline signal for approximately 10 minutes, the compound of Example 4 was added stepwise to final concentrations of 300 nM and 1 uM. Dissociation was initiated by replacing the medium with 3 ml of fresh medium when the binding curve obtained sufficient curvature at at least one concentration. Off-target binding of the radiolabeled molecule was investigated by using a plastic surface in a cell-free area on the same dish as a reference background region. The reference background signal was automatically subtracted from the attenuated target region signal, which yielded a specific real-time binding curve of the compound of Example 4 to target cells. Dynamic interaction evaluation was performed using TraceDrawer 1.9.2 (Ridgeview Instruments AB, Uppsala, Sweden).
[0189] Figures 5A–5D show the 1:1 and 1:2 kinetic analyses of the real-time binding curves of the compound in Example 4 in the human colorectal cancer cell line HT-55. The solid line represents the calculated fit. The recorded curve can be seen to be close to the 1:2 fit, indicating a 1:2 kinetic fit. [Table 3]
[0190] Table 3 shows the equilibrium dissociation constants (K) determined for the compounds of Example 4 in the human colorectal cancer cell line HT-55. D This indicates that the compounds of formula I can be used in the diagnosis, treatment, and / or prevention of colorectal cancer that express elevated levels of NK1 receptors.
[0191] chromosome assay The cellular uptake of the compound from Example 4 in the human NB cell line IMR-32 was investigated using a specificity assay.
[0192] Total 2 x 10 5 Cells / well were seeded in 24-well plates and incubated at 37°C for 48 hours. The old medium was removed and replaced with either the compound from Example 4 (10 nM) or a combination of the compound from Example 4 (10 nM) and aprepitant (1 μM). The treated cells were then incubated for 1 hour. The medium was removed, the cells were trypsinized, i.e., dissociated using trypsin, and the fractions were collected in fraction tubes. Radioactive uptake in each fraction tube was measured using a gamma counter (1480 Wizard 3”, Wallace). Differences in the amount of bound radioactivity between treatment groups were calculated using an unpaired t-test.
[0193] Figure 6 shows the cellular uptake concentration of the compound from Example 4 (10 nM) per 100,000 cells, both for the compound from Example 4 alone and in combination with aprepitant (1 μM).
[0194] The specificity assay showed NK1R-targeted uptake of the compound from Example 4 at a concentration of 10 nM, blocked by aprepitant at a concentration of 1 μM, which was 100 times stronger than that of the compound from Example 4.
[0195] This demonstrates the specific binding of the compound in Example 4 to NK1R, which is important to ensure the specific accumulation of the compound at the intended therapeutic site and to avoid nonspecific uptake in healthy tissues / organs, thus minimizing associated side effects.
[0196] Further Specific Assays NK1R-transfected U2OS cells (TACR1(NK1) / U2OS, "U2OS-NK1R") were seeded in 10 wells of a 48-well plate containing 500 μL of DMEM medium supplemented with 10% FBS and 1% penicillin-streptomycin per well. Wild-type, untransfected U2OS cells were seeded in an additional 10 wells of a 48-well plate containing 500 μL of DMEM medium supplemented with 10% FBS and 1% penicillin-streptomycin per well. The cells were then incubated at 37°C for 48 hours in a 5% CO2 atmosphere. After the incubation period, the medium was aspirated and the wells were washed twice with PBS.
[0197] To prepare the "blocked" wells, five of the wells containing U2OS-NK1R cells and five of the wells containing wild-type U2OS cells were pretreated with 500 nM aprepitant in 100 μL of DMEM medium containing 1% penicillin-streptomycin per well. The remaining five U2OS wells and five U2OS-NK1R wells were then treated with 100 μL of DMEM medium containing 1% penicillin-streptomycin per well. After incubation of 100 μL of 10 nM of the compound from Example 49 at 37°C for 10 minutes, the cells were treated in DMEM medium containing 1% penicillin-streptomycin. 125 The compound containing I was added to each well and incubated at 37°C for an additional 30 minutes.
[0198] After incubation with the compound of Example 49, the radioactive medium was aspirated and the cells were washed with PBS. The cells were then trypsinized, i.e., dissociated using trypsin, counted using a TC20® automated cell counter (BioRad, Sweden), and cell-associated radioactivity was measured using a gamma counter (1480 Wizard 3', Wallace, Finland). Statistical significance was assessed using Student's t-test, and the data were analyzed to determine the pmol of the compound of Example 49 per 100,000 cells. The results are shown in Figures 8A and 8B. Error bars in the figures indicate 95% confidence intervals.
[0199] Figure 8A shows the amount of the compound from Example 49, measured as bound pmol (i.e., picomoles) per 100,000 NK1R-transfected U2OS cells. It is evident from Figure 8A that there was NK1R-targeted uptake of the compound from Example 49 at a concentration of 5 nM, which was blocked by aprepitant at a concentration of 250 nM. Figure 8B shows the amount of the compound from Example 49, measured as bound pmol (i.e., picomoles) per 100,000 untransfected wild-type U2OS cells. Figure 8B does not show NK1R-targeted uptake of the compound from Example 49. It was concluded that the compounds of this disclosure, such as the compound of Formula I, specifically bind to NKR1. This specific binding is important to ensure specific accumulation of the compound at the intended therapeutic site and to avoid nonspecific uptake in normal tissues / organs, minimizing associated side effects.
[0200] Competitive assay For real-time competitive binding experiments on NK1R-expressing U2OS osteosarcoma cells (TACR1(NK1) / U2OS), 1.5–2.0 × 10⁶ 6 The cells were seeded in an inclined dish (Nunc® cell culture / Petri dish, catalog no. 150350, ThermoFisherScientific) and incubated overnight at 37°C and 5% CO2. The following day, the culture medium (Dulbecc's Modified Eagle Medium Supplement, as described in the summary section) was replaced with 10 mL of fresh medium, and the dish was incubated horizontally overnight.
[0201] Dynamic measurements were performed using a LigandTracer Green (Ridgeview Instruments AB, Uppsala, Sweden) with a blue (488nm) to green (535nm) detector at ambient temperature.
[0202] Before binding measurement, the cell medium was switched to 3 ml of CO2-independent medium (Gibco, catalog no. 18045-054), supplemented with 10% (v / v) fetal bovine serum (FBS), and the dish was placed on the instrument's inclined rotating support. After recording the baseline signal for 30 minutes, 90 nM FAM-labeled substance P, FAM-SP, was added to the cells, and signals from the cell target and background reference region were recorded over time. After sufficient curvature of the binding curve was obtained (usually about 60 minutes), 90 nM competing compounds (Examples 7, 8, 9, 10, 11, 13, 14, and 15) were consequently added. The fluorescence signal was recorded for at least 60 minutes.
[0203] Dynamic evaluation was performed using TraceDrawer 1.9.2 software (Ridgeview Instruments AB, Uppsala, Sweden) with a one-to-one competition model.
[0204] Figures 7A and 7B show the background-corrected binding signal of FAM-SP, followed by the competition phase in which the evaluated compounds (compounds from Examples 7–10 in Figure 7A, and compounds from Examples 11 and 13–15 in Figure 7B) compete with FAM-SP for binding, resulting in a FAM-SP signal with reduced compound-dependent levels. Positive control aprepitant and SP are shown for comparison. It was concluded that the compounds of this disclosure demonstrate NK1R-specific binding to epitopes overlapping with FAM-SP. The percentage of FAM-SP substitution 60 minutes after the addition of competing compounds is reported in Table 4 below.
[0205] Further competitive assays Further competitive testing was conducted using the compounds of the examples described herein, (i) FAM-SP and (ii) 125 I-SP, that is, 125 This was carried out by testing the substitution of SP labeled with I.
[0206] FAM-SP substitution was performed using the competitive assay described above. The results are shown in Table 4.
[0207] The compounds from Examples 5, 14, 15, 18, 27, and 32 were sent to Eurofins Cerep SA in Celle-Levescault, France, and tested using the LeadHunter assay for NK1 human tachykinin GPCR-binding agonist radioligands. The assay was performed on membrane preparations derived from U373MG cells and 125 I-substance P LYS3 was used as the ligand at 0.05 nM. The compound was tested in two ways at eight concentrations ranging from 30 pM to 100 nM. IC 50 The calculations were provided by Eurofins Cerep. For comparison, the reference compound [Sar9,Met(O2)11]-SP was measured at 167 pM IC2. 50 He gave it.
[0208] The results are shown in Table 5. [Table 4-1] [Table 4-2]
[0209] Therefore, the compounds of this disclosure enable substitution of FAM-SP. [Table 5]
[0210] Table 5 shows that the compounds of this disclosure enable binding to NK1R. In particular, the compounds of this disclosure in which Q is nitrogen, for example, the compounds of Examples 14 and 32, have high affinity for NK1R.
