Abstract
Description
[Technical Field]
[0001] This invention relates to compounds useful for visualizing cellular senescence in vitro and in vivo, the preparation of such compounds, and the use thereof. Specifically, this invention relates to novel glycosides for use as senescence tracers in vitro and in vivo. [Background technology]
[0002] Cellular senescence is a biological process in which cells deviate from their proliferation cycle. Cellular senescence was first characterized in fibroblasts, which were observed to be able to passage only a limited number of times before their proliferation permanently ceased. This phenomenon, known as the Hayflick limit, can explain the physiological process of aging. Cellular senescence involves clear changes in metabolic pathways (Roninson, EB, Tumor Cell Senescence in Cancer Treatment, Cancer Res., 2003, 63:2705-2715).
[0003] Senescent cells exhibit aging-related secretory phenotypes, including pro-inflammatory cytokines and growth factors. Under certain circumstances, removing senescent tissue from patients can provide significant benefits. Furthermore, aging is recognized to play a crucial role in cancer treatment and treatment resistance. Inducing aging through treatment can establish stable clinical endpoints and thus may serve as a criterion for the success of chemotherapy. In addition, detecting senescent cells in diagnostic tests may enable the detection of preneoplastic lesions (Roninson, EB, Tumor Cell Senescence in Cancer Treatment, Cancer Res., 2003, 63:2705-2715; and Campisi, J. and d'Adda di Fagagna, F., Cellular Senescence: when bad things happen to good cells, Nature Reviews Molecular Cell Biology, 2007, 8:729-740).
[0004] The most widely used surrogate marker for senescent cells is senescence-related β-galactosidase (Roninson, EB, Tumor Cell Senescence in Cancer Treatment, Cancer Res., 2003, 63:2705-2715). However, substrates for such β-galactosidases have the drawback that they can only be used to track β-galactosidase expression ex vivo and in vitro.
[0005] In recent years, β-galactosidase-specific PET (positron emission tomography) tracers for in vivo imaging of tumor aging have been reported. For example, the PET tracer [ 18 [F]FPyGal enables non-invasive imaging of β-galactosidase as a surrogate marker for aging. However, this compound has the disadvantage of having a short retention time. [Overview of the project] [Problems that the invention aims to solve]
[0006] This invention aims to solve the above-mentioned problems related to compounds in the prior art.
[0007] There is a need for novel compounds that can act as tracers for cellular senescence, which may be used simultaneously in vitro and in vivo. There is also a need for radiotracers for cellular senescence with extended intracellular retention times. Furthermore, there is a need for radiotracers for senescent cells that accumulate in localized areas within senescent cells. In addition, there is a need for improved methods to obtain high-resolution / improved imaging at low and / or the same radiation dose in the treatment of disorders associated with cellular senescence (e.g., cancer). Furthermore, the present invention aims to provide an alternative method for selectively eliminating senescent cells in vivo. Furthermore, the present invention aims to provide an alternative means for measuring the efficiency of cancer treatment. [Means for solving the problem]
[0008] This invention is based on the finding that several types of radioactive tracers can be retained within cells by utilizing various mechanisms, specifically by self-destructive mechanisms that may involve chemical binding or sorption processes to cellular components. This allows for the proactive extension of the retention time of radiolabeled hexose derivatives within senescent cells, thereby enabling and facilitating the labeling and detection of senescent cells both in vitro and in vivo.
[0009] Therefore, the present invention is Formula: GSL (In the formula, G is a glycoside, a substituted or unsubstituted C1-C5 alkyl derivative thereof, and / or a substituted or unsubstituted N-acetyl derivative thereof, having a glycosidic bond to S; * indicates the binding site between G and S; S is

[0010] Surprisingly, the compounds of the present invention were found to be selectively and highly concentrated in senescent cells. While we do not wish to be bound by any particular theory, it is hypothesized that, based on their binding mechanism, the compounds of the present invention accumulate in localized areas within senescent cells, such as organelles. Such localized concentration within cells facilitates in vivo targeting and elimination of cells (especially tumors). Furthermore, generally speaking, using the radiolabeling of the present invention offers the advantage of significantly improved sensitivity compared to conventional labeling methods. This is partly due to the high tissue penetration of gamma photons emitted from the radiolabeling and the very high sensitivity of the radiation detector used. Thus, the compounds of the present invention enable quantitative, selective, and sensitive in vivo detection of senescent cells (especially tumors). It is believed that the highly selective concentration of the compounds of the present invention, using detectable radiolabeling or therapeutic radioresidues, in senescent cells can be utilized to diagnose or treat age-related diseases.
[0011] Another advantage is that tumors can be treated using non-invasive methods. For example, when a compound of the present invention having a therapeutic radioactive residue is administered, the tumor can be treated because almost all of the compound is taken up by the tumor tissue. A further advantage of using the compounds of the present invention is their flexibility. For example, the compounds of the present invention can be easily provided with detectable radiolabels or therapeutic radioactive residues, so they can be easily adapted to various changing needs in the clinical field.
[0012] A further advantage is that radiolabeling can be performed in the final synthesis step, and this radiolabeling can be carried out using a relatively simple method. This makes it possible to perform the final synthesis step at or near the site where the compound of the present invention is administered, such as in a hospital. As a result, 18 F 64 This allows for the administration of compounds with relatively short half-lives, such as Cu. Furthermore, a fully equipped laboratory for the initial synthesis of the compounds of the present invention is not required in the facility where the compounds of the present invention are administered.
[0013] The compounds of the present invention may exist in the form of stereoisomers (enantiomers, diastereomers), depending on their structure. Therefore, the present invention also encompasses enantiomers or diastereomers, and mixtures thereof. Stereoisomerically homogeneous components can be isolated from mixtures of enantiomers and / or diastereomers by known methods. If the compounds of the present invention are produced in the form of tautomers, the present invention encompasses all tautomers. Tautomers are structural isomers of the compounds of the present invention that can be readily converted to each other. Furthermore, the compounds of the present invention may exist in the form of prodrugs. Prodrugs are pharmacologically inactive compounds of the present invention that are metabolized into pharmacologically active drugs after ingestion.
[0014] A salt suitable for the purposes of the present invention is a pharmaceutically acceptable salt of the compound of the present invention. However, the present invention also includes salts that are not suitable for pharmaceutical use but can be used, for example, for the isolation or purification of the compound of the present invention.
[0015] Generally, salts are electrically neutral because they consist of a specific number of cations and a corresponding number of anions. In the preparation of a particular salt, a counterion corresponding to that salt is used, and it is not considered necessary to explicitly state such counterions here.
[0016] The pharmaceutically acceptable salts and their preparations are well known in the art. For types and preparations of such pharmaceutically acceptable salts, see Stahl, PH and Wermuth, CG, Handbook of Pharmaceutical Salts Properties, Selection and Use, Weinheim / Zurich: Wiley-VCH, 2011, and Gupta D., et al., Salts of Therapeutic Agents: Chemical, Physicochemical, and Biological Considerations, Molecules. 2018 Jul; 23(7): 1719, the contents of which are incorporated herein by reference in their entirety.
[0017] Examples of pharmaceutically acceptable salts of the compound of the present invention include inorganic salts such as ammonium salts, alkali metal salts, and alkaline earth metal salts; organic salts; or salts with basic amino acids. Furthermore, salts with inorganic acids or acidic amino acids are also examples.
[0018] The compounds of the present invention and their salts may exist in the form of solvates. In such cases, the compounds of the present invention or their salts (particularly pharmaceutically acceptable salts) exist in a solid or liquid state in which solvent molecules coordinate to form complexes. A hydrate is a specific form of solvate in which water is coordinated.
[0019] A "glycoside" generally refers to a molecule in which a sugar is attached to another residue or group via a glycosidic bond or glycosidic linkage. Glycosides include hexoses, and examples of hexoses include aldohexoses such as allose, altrose, glucose, mannose, growth, idose, galactose, and talose, and ketohexoses such as psicose, fructose, sorbose, and tagatose. The glycoside of the present invention is preferably a D isomer. A particularly preferred example of a glycoside is β-D-galactosidase.
[0020] The glycosides of the present invention can exist as substituted or unsubstituted C1-C5 alkyl derivatives and / or substituted or unsubstituted N-acetyl derivatives. Therefore, one or more hydroxyl groups may be unmodified, modified with substituted or unsubstituted C1-C5 alkyl residues as described later, or substituted with substituted or unsubstituted N-acetyl residues. Thus, it can be easily understood that a variety of glycoside derivatives exist, including, for example, substituted or unsubstituted C1-C5 alkyl derivatives having one substituted or unsubstituted C1-C5 alkyl residue at the terminal hydroxyl group, and substituted or unsubstituted N-acetyl derivatives having one substituted or unsubstituted N-acetyl substitution near the glycosidic bond. Furthermore, glycoside derivatives having one or more substituted or unsubstituted C1-C5 alkyl residues and / or substituted or unsubstituted N-acetyl residues are also included.
[0021] When the glycoside of the present invention is a substituted or unsubstituted C1-C5 alkyl derivative and / or a substituted or unsubstituted N-acetyl derivative, the compound of the present invention is expected to have a longer retention time compared to the unmodified glycoside because it inhibits enzymatic cleavage. Therefore, the compound of the present invention may be present in high concentrations in senescent cells.
[0022] The term "alkyl" generally refers to branched or linear alkyl groups, C1-C 18 Alkyl, for example, C1-C 16 Alkyl, C1-C14 Alkyl, C1-C 12 Alkyl, C1-C 10 The alkyl, C1-C8 alkyl, or C1-C6 alkyl is preferred, and C1-C5 alkyl is more preferred. Examples of C1-C5 alkyl include methyl, ethyl, propyl, butyl, isopropyl, isobutyl, tert-butyl, n-pentyl, 2-pentyl, 3-pentyl, 2-methylbutyl, 3-methylbutyl, 3-methylbuta-2-yl, 2-methylbuta-2-yl, and 2,2-dimethylpropyl.
[0023] The term "alkenyl" generally refers to a partially saturated or fully saturated branched or linear alkyl residue. Therefore, an alkenyl residue has at least one CC double or CC triple bond.
[0024] The term "aryl" refers to a substantially aromatic monocyclic or polycyclic ring containing carbon and hydrogen atoms. The aromatic ring may preferably satisfy Hückel's rule. The aryl group is preferably a monocyclic or bicyclic ring, more preferably a monocyclic ring, which contains 4 to 8 carbon atoms. The molecular weight of the aryl residue is more preferably 500 g / mol or less, for example, 400 g / mol or less, 300 g / mol or less, or 200 g / mol or less.
[0025] The term "heteroaryl" refers to a substantially aromatic monocyclic or polycyclic ring containing a carbon atom, a hydrogen atom, and at least one heteroatom, preferably containing 1 to 4 heteroatoms independently selected from nitrogen, oxygen, and sulfur, for example, 3 heteroatoms, 2 heteroatoms, or 1 heteroatom. Therefore, it is preferable that the heteroaryl satisfies Hückel's rule. The heteroaryl group is preferably a monocyclic or bicyclic ring, more preferably a monocyclic ring, which contains 2 to 6 carbon atoms and 1 to 3 heteroatoms. The molecular weight of the heteroaryl residue is preferably 500 g / mol or less, for example, preferably 400 g / mol or less, 300 g / mol or less, or 200 g / mol or less.
[0026] In this specification, the term “substitution” means modification of a carbon chain by the attachment of one or more residues to an alkyl group such as a C1-C5 alkyl, cycloalkyl, or heterocycloalkyl group, and / or the introduction of one or more heteroatoms (e.g., N, S, or O). Furthermore, the residues may be selected from the group consisting of fluorine, chlorine, bromine, and iodine; methyl groups; ethyl groups; and functional groups such as hydroxyl groups, amino groups, O-alkyl groups (especially C1-C5O-alkyl), nitro groups, and carboxyl groups. The total molecular weight of the residues attached to a specific alkyl group such as a C1-C5 alkyl moiety, cycloalkyl moiety, or heterocycloalkyl moiety is preferably 250 g / mol or less, and more preferably 150 g / mol or less or 100 g / mol or less. Preferred substituents for the C1-C5 alkyl residues include compounds such as CH2-O-CH2, C2H4-O-CH2, CH2-O-CH2-O-CH2, CH2-O-CH2-O-CH2, C2H4-O-CH2-O-CH2, CH2-O-C2H4-O-CH2, C2H4-O-C2H4-O-CH2-O-C2H4, CH2-O-CH2-O-CH2-O-CH2, C2H4-O-CH2-O-CH2-O-CH2, and CH2-O-C2H4-O-CH2-O-CH2.
[0027] The term "halogen" or "halo" refers to fluorine, chlorine, bromine, or iodine, and is preferably fluorine, chlorine, or bromine. In some embodiments, the term "halogen" or "halo" is: 76 Br, 75 Br, 19 F and 18 It is preferable to refer to F.
[0028] The term "methylhalogen" refers to a methyl group having one fluorine, chlorine, bromine, or iodine atom, or a methyl group having two or three halogens independently selected from fluorine, chlorine, bromine, and iodine. In some embodiments, the methylhalogen is 76 Br, 75 Br, 19 F or 18 It is preferable that it has F.
[0029] The term "detectable radioactive label" is, for example, 11 C, 40 K, 13 N, 15 O, 18 F, 75 Br, 76 Br, 82 Rb, 68 Ga, 64 Cu, 62 Cu, 89 Zr, 123 I, 124 I, 125 I, 131 I, 210 At, 211 At and 111 It contains In. Detectable radioactive labels include: 11 C, 18 F, 68 Ga, 64 Cu and 124 I is preferred. Detectable radiolabeling enables quantitative and / or qualitative evaluation of senescent cells, as well as identification of their localization, particularly in vivo. Senescent tissue may be appropriately identified and, for example, surgically removed with high selectivity. 18F is particularly preferred because, when it decays, it does not generate non-radioactive elements, and the compound of the present invention can be decomposed in vivo, allowing the compound to be removed from the cell without causing further damage to the cell itself or the organism to which the cell belongs.
[0030] Alternatively, complexes coordinated to such atoms are included. In this case, the complex may be called a chelating agent coordinated to a detectable radioactive label. A (coordination) complex has an atom or ion (usually a metal atom or metal ion) at its center, with ligands or complexing agents arranged around it. The central atom or ion is usually a detectable radioactive label. Therefore, the Z residue includes the central atom or ion and the ligands or complexing agents arranged around it. Specific examples of such chelating agents coordinated to detectable radioactive labels are well known to those skilled in the art. Such chelating agents are preferably amino acids, and preferably amino acids that make up proteins / natural amino acids (e.g., histidine). Other examples of suitable chelating agents include DOTA, NOTA, NODAGA, and desferrioxamine (e.g., desferrioxamine B).
[0031] In this specification, the term "therapeutic radioactive residue" is defined as follows: 32 P, 60 Co, 89 Sr, 186 Re, 153 This refers to atoms such as Sm. Other examples of therapeutic radioactive residues include the previously mentioned examples of detectable radiolabels. 125 I and 131 I was mentioned, and also, 86 Y, 111 In, 177 Lu and 67Cu is an example. Alternatively, complexes coordinated to such atoms are included. In this case, the complex may be called a chelating agent coordinated to a therapeutic radioactive residue. In the treatment of cellular aging disorders (especially cancer), the use of the compounds of the present invention having therapeutic residues allows for the combination of the target selectivity of the compounds of the present invention with systemic effects such as chemotherapy, and can be used as part of a therapeutic strategy aimed at cure or control and mitigation of disease.
[0032] In particular, it has already been demonstrated that β-galactosidases derived from humans or animals can tolerate glycosides to which large residues are bound without affecting their enzymatic activity, even if such large residues are bound to the glycoside. Therefore, it can be reasonably predicted that the compounds of the present invention having bulky therapeutic radioactive residues can be converted by β-galactosidases derived from humans or animals.
[0033] It is understood that therapeutic radioactive residues may be prepared and bound to the compound of the present invention in the same manner as detectable radiolabels. Preferably, the therapeutic residues and the detectable labels are the same, thereby enabling the diagnosis and treatment of cellular aging-related disorders (especially cancer).
[0034] In the above formula, the ends of the bonded parts of the group represented by G, marked with an asterisk (*), are not carbon atoms or CH2 groups, but rather the parts that constitute the bond to the atom to which G is bonded.
[0035] In the above formula, the ends of the bonds of the group represented by S, marked with * or #, are not carbon atoms or CH2 groups, but rather the parts that constitute the bond to the atom to which S is bonded.
[0036] In the above formula, the end of the bond of the group represented by L, marked with a #, is not a carbon atom or a CH2 group, but rather the part that constitutes a bond to the atom to which L is bonded.
[0037] In this invention, the terms “having / including” or “having / including” are open-ended terms and do not exclude any other elements other than those explicitly stated.
[0038] In this invention, the terms "consisting of" or "making up" are closed-end terms that exclude any elements other than those explicitly stated.
[0039] In the present invention, the terms "substantially consisting of" or "substantially consisting of" are partially closed-end terms and refer to preparations having additional components other than those described, to the extent that they do not significantly alter the properties of the preparation according to the present invention.
[0040] In the present invention, when a preparation is described using the terms "having" or "having," it clearly includes a preparation comprising the said components, or a preparation substantially comprising the said components.
[0041] As used herein, radiation medicine refers to any type of equipment or device that can detect the Z residues of the present invention, namely, detectable radioactive labels, therapeutic radioactive residues, chelating agents coordinated with detectable radioactive labels, or chelating agents coordinated with therapeutic radioactive residues, and generate visual signals or images. Preferably, the device can identify the location of Z residues in the body of a mammal. Specific examples of radiation medicine include, but are not limited to, positron emission tomography (PET) that can create three-dimensional images or maps of the functional processes in the body. This system detects gamma-ray pairs indirectly emitted from a radioactive isotope that emits positrons and is bound to a metabolic active molecule (i.e., a substrate of β-galactosidase) and introduced into the body. Next, through computer analysis, the spatial location of metabolic activity is reconstructed as an image, and this image is supplemented with a CT X-ray scan performed on the patient with the same device, preferably simultaneously, in the same examination, to obtain a three-dimensional image capable of identifying the location of tissues enriched with the prodrug. In positron emission, a proton is converted into a neutron, a positron, and a neutrino by the weak force. Isotopes that have undergone so-called β+ decay emit positrons. Suitable positron-emitting radionuclides for this purpose include 11 C, 40 K, 13 N, 15 O, 18 F, 75 Br, 76 Br, 89 Zr, 82 Rb, 68 Ga, 62 Cu and 64 Cu, among which 11 C and 18 F are preferred. Other useful radionuclides include 123 I, 124 I, 125 I, 131 I, 210 At, 211 At and 111In is one example. Furthermore, the compounds of the present invention may be labeled with technetium and rhenium isotopes using known chelate complexes. Methods for preparing radionuclides and radiolabeling compounds are well known to those skilled in the art. US2007 / 0273308 and WO2007 / 122488 (the contents of these documents are incorporated herein by reference in their entirety) relate, for example, to the preparation of radionuclides. Radiolabeling is outlined, for example, in WO2007 / 148089 and WO2007 / 148083 (the contents of these documents are incorporated herein by reference in their entirety).
[0042] PET is preferably connected to a computed tomography (CT) scanner. Such a PET / CT system enables quantitative detection of signals and allows the detected signals to be attributed to specific tissues, that is, the localization of the radionuclide used, i.e., the prodrug bound to it, to be identified. The functions, procedures, and equipment of PET / CT are well known to those skilled in the art. Other suitable methods include single-photon emission computed tomography (SPECT) and methods based on nuclear magnetic resonance (NMR) that detect the quantum mechanical magnetic properties of atomic nuclei.
[0043] The radiomedical equipment used is preferably a PET scanner, and more preferably a PET / CT scanner or a PET / MR scanner. [Brief explanation of the drawing]

Furthermore, intracellular accumulation may be based on a self-destructive mechanism involving chemical bonding or sorption processes to cellular components. Moreover, intracellular accumulation is more preferably accompanied by bonding of the compounds of the present invention, for example, covalent and / or ionic bonding. For example, bonding to intracellular components such as proteins, for example, covalent and / or ionic bonding, may occur.
[0066] The basic principles of the present invention are schematically shown in the following schemes 1 and 2.
[0067] According to Scheme 1, for example, a radioactive tracer that is PIPGal is R 1 It contains a basic functional group in its vicinity, specifically a tertiary amine. In this respect, in particular, [ka] The compound showed good results, and this compound, [ka] It is preferable that this be the case. When the glucosidase moiety is cleaved by aging-related β-galactosidase (SABG) or β-galactosidase, R 1 Nitrogen adjacent to the residue can be readily protonated within the acidic lysosomes of the target cell and captured within these acidic lysosomes. This so-called pH capture is presumed to be due to the sorption (particularly adsorption) of ammonium groups to negatively charged cellular components, such as negatively charged amino acids of proteins. The radiolabeled alcohol accumulated and captured in the acidic lysosomes may be detected by radiomedical equipment such as PET / CT scanners.
[0068] [ka]
[0069] Scheme 2 illustrates a second method. In this method, the glucosidase portion is cleaved by aging-related β-galactosidase (SABG), and a structure that degrades into a quinone methide appears in the alcohol. This quinone methide reacts with amino acid residues (particularly cysteine and lysine residues) of proteins present in the target cell (indicated by arrows) to form a secondary amine, creating a bond with these amino residues. In the secondary amine formed by this so-called quinone methide bond, one residue remains (still) bound to the protein, while the other residue is bound to the original radiolabeled tracer residue. This radiolabeled alcohol bound to the intracellular protein may be detected by radiomedical equipment such as a PET / CT scanner.
[0070] [ka]
[0071] The compounds of the present invention may be prepared as shown in the following schematic diagram.
[0072] [ka]
[0073] In the first step, a hexose precursor having bromine at the glycosidic bond position and having multiple acetylated hydroxyl groups is reacted with hydroxybenzaldehyde, preferably 2-hydroxybenzaldehyde, and a nitro group (e.g., 2-hydroxy-5-nitrobenzaldehyde) to form glycoside 1. The aldehyde group is converted to alcohol 3, in which the nitro group is protected with, for example, a tert-butyloxycarbonyl (Boc) protecting group, and in which 4, for example, a methylsulfonyl (MS) group is introduced to the alcohol. This converts the alcohol to a suitable leaving group, generating an alkylating agent. This method allows for the introduction of aryl leaving groups necessary for the self-destructive reaction and the generation of quinone methides.
[0074] [ka]
[0075] The methylsulfonyl-activated hydroxyl group of the Boc-protected methylsulfonyl-substituted precursor 4 is converted to ether 5 or ether 10. In the next step, the Boc protecting group is converted to a secondary amine 6 or secondary amine 11 having a hydroxyl moiety, and this amine is further converted to a mesyl group 7 or mesyl group 12 and activated, enabling radiofluorination in a later step.
[0076] [ka]
[0077] The Boc protecting group of ether 5 or ether 10 in scheme 4 is converted to a secondary amine having a fluorine moiety. Next, the acyl group of the hexose moiety is removed to obtain non-radioactive standard 9 or non-radioactive standard 14.
[0078] [ka]
[0079] In the first step, a brominated and acetylated hexose derivative (e.g., acetobromogalactose) is converted using the protected 4-(piperazin-1-yl)phenol derivative 15, and then deprotected to obtain a Boc-protected glycoside 16, which is further converted to a mesylate ester 18. A non-radioactive standard may also be synthesized by reacting an acetylated hexose derivative (e.g., acetobromogalactose) with the protected 4-(piperazin-1-yl)phenol derivative 15, followed by alkylation 19 and deprotection 20.
[0080] [ka]
[0081] As shown in Scheme 7, the hexose derivative is converted using a substituted (iodine-substituted or bromine-substituted) orthosalicylaldehyde to obtain compound 21, and then this compound is converted with NaBH4 to obtain alcohol 22. In 23, the alcohol is mesylated and then converted to tetrafluorophenyl ether 24. Next, the iodine substituent or bromine substituent is reacted to obtain compound 25.
[0082] [ka]
[0083] The hexose derivative is reacted with fluorine-substituted orthosalicylaldehyde to obtain compound 26, which is then converted with NaBH4 to obtain alcohol 27. Next, this alcohol is converted to tetrafluorophenyl ether 28 and deacetylated.
[0084] The compounds of the present invention exhibit unexpected and beneficial pharmacological effects. These compounds can label senescent cells in vitro and in vivo. Specifically, labeling senescent cells with the compounds of the present invention in vivo allows for clear identification of senescent cells during surgical procedures, making it possible to target and eliminate senescent cells (especially cancer cells).
[0085] The foregoing description is illustrative only and not limiting. Those skilled in the art will readily be able to implement numerous embodiments by examining the foregoing description. For example, the present invention primarily describes the synthesis of tracer 9 and diagnostic use thereof. It goes without saying that any suitable detection labels and therapeutic residues of any kind may be synthesized and conjugated to the compounds of the present invention. Therefore, the scope of the present invention is not defined by the foregoing description, but should be defined by the entire scope equivalent to the appended claims and assertions.
[0086] Unless otherwise stated, in the following tests and examples, percentages are expressed in weight percentages, and parts are expressed in parts by weight. Solvent ratios, dilution ratios, and liquid / solution concentrations are all based on volume. The notation "w / v" means "weight / volume." Therefore, for example, "10 w / v%" means that 10 g of the substance is contained in 100 ml of solution or suspension. [Examples]

[0094] The performance of the radiochemical reaction was monitored by radio-TLC using a 0.20 mm Polygram SIL G / UV254 (silica gel 60) TLC plate. The radio-TLC plate was developed with an appropriate running buffer / solvent mixture. Radio-TLC data were acquired using the Cyclone Plus storage phosphor imaging system (PerkinElmer, Waltham, Massachusetts, USA).
[0095] [ 18 F]PIPGal's automatic compositing (FX N Pro) Precursor 18 (10 mg) dissolved in DMSO (500 μL) was added to a reactor containing azeotropically dried fluoride and heated at 150°C for 15 minutes. Next, the reactor was cooled to 40°C, and 0.1 M NaOH (1.0 mL) was added. The reaction mixture was stirred at 40°C for 2 minutes, and then 0.1 M NaH2PO4 (2.0 mL) was added. The mixture was purified using semi-preparative HPLC (Luna 5 μm C18(2) 100 Å 250 × 4.6 mm, Phenomenex) at a flow rate of 6 ml / min with phosphate-buffered saline (PBS) containing 10% EtOH. Based on the radioactive signal (13-14 minutes), the product was collected and transferred to a product vial.

[0096] [ 18 F] Automatic compositing of TFBB Gal (FX N Pro) To the dried fluoride, a DMA (700 μL) solution containing 25 mg of precursor, 3.26 μL of pyridine, and 3.7 mg of Cu(OTf)2 was added. The reaction mixture was heated at 120°C for 20 minutes and then cooled to 40°C. Deprotection was performed by adding 1 mL of 2 M NaOH and reacting at 40°C for 10 minutes. Next, 500 μL of 0.3 M HCl was added to the reaction mixture. This mixture was passed through an alumina N cartridge and diluted with a solution containing 500 μL of 4 M HCl and HPLC eluent (2 mL). The mixture was then purified by semi-preparative HPLC (Luna 5 μm C18(2) 100 Å 250 × 4.6 mm, Phenomenex) using an eluent containing a 0.1% TFA aqueous solution of 35% MeCN at a flow rate of 6 mL / min.

Purity was evaluated by radio-TLC using ethyl acetate.
[0097] Biological experimental methods Cells were cultured at 37°C under 5% CO2 in a wet incubator (Binder, Tuttlingen, Germany). Fetal bovine serum (FBS, Sigma, a subsidiary of Merck) was inactivated by heating at 57°C for 30 minutes and used as a cell culture additive. For in vitro uptake experiments, cells were rinsed with DPBS, collected with a cell scraper, and then centrifuged. Next, the cell pellet was washed with DPBS, resuspended in DPBS, and the cell count was measured. 1 × 10⁻⁶ 6 0.74 MBq of tracer was added to a 1 mL DPBS suspension containing 2480 cells and incubated at 37°C for 40 minutes under 5% CO2. After the prescribed incubation time, the suspension was centrifuged. The cell pellet was transferred to a new gamma counter tube (Sarstedt), washed twice with 1 mL of DPBS, and then resuspended in 1 mL of DPBS. The uptake rate was 2480 Wizard 2 The measurement was performed using an automated gamma counter (PerkinElmer).
[0098] X-gal staining was performed to confirm senescence in vitro. For X-gal staining, cells were fixed at room temperature for 15 minutes in a DPBS solution of 0.25% glutaraldehyde (Sigma-Merck, a subsidiary of Merck) and 2% formaldehyde (Sigma-Merck, a subsidiary of Merck). Next, the cells were washed twice with a DPBS solution of 1 mM magnesium chloride (MgCl2, Sigma-Merck, a subsidiary of Merck) (pH 6.0) and incubated at 37°C. A freshly prepared staining solution, which had been warmed and filtered beforehand, was added. The staining solution contained 1 mg / mL of 5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside (X-gal, PEQLAB / VWR from Avantor), 5 mM potassium hexacyanoferrate(III) [K3Fe(CN)6, Sigma-Merck], and 5 mM potassium hexacyanoferrate(II) [K4Fe(CN)6, Merck] in a 1 mM MgCl2 / DPBS solution (pH 6.0). Each sample was wrapped in aluminum foil to protect it from light and prevent evaporation. Next, each sample was washed twice with a 1 mM MgCl2 / DPBS solution (pH 6.0) and then observed under an optical microscope (Axiovert 200 equipped with AxioCam and AxioVision, Carl Zeiss, Oberkochen, Germany).
[0099] The animal manipulation was approved by the local government (Regierungspraesidium Tübingen, Germany) and carried out in accordance with the German Animal Welfare Act. The mice used were 6-7 weeks old. The tumors measured 0.5 × 10⁻⁶. 6 The cells were subcutaneously administered and transplanted into the right flank of SCID beige mice. The majority of the tumor was 100 mm. 3 At the point when the mice reached a certain stage (approximately 3 weeks after vaccination), they were randomly divided into two groups. Each group received intraperitoneal administration of 25 mg / kg / day of CX-5461 (AdooQ BioScience, Irvine, California, USA) or a solvent [50 mM monosodium phosphate (Sigma-Merck, a subsidiary of Merck, Darmstadt, Germany), pH 4.5] for 5 consecutive days.
[0100] Anatomical imaging was performed using a 7 Tesla small animal MRI scanner equipped with a rat-specific whole-body coil and Paravision® software (Bruker, Billerica, Massachusetts, USA). To ensure accurate positioning, the rats were fixed and transferred to the PET scanner. After administering 12±1 MBq of tracer (measured with a CRC 15-R dosimeter) to the rats via a tail vein catheter, the catheter was flushed with 50 μL of heparinized saline. 57 Transmission scans were performed using an external point source of Co, and attenuation correction was applied. Static radiation scans were acquired 50-60 minutes after tracer administration.
[0101] The raw data in list format was histogrammed and reconstructed using the OSEM3D / SP-MAP algorithm implemented in Inveon Acquisition Workplace. The reconstructed PET images and their corresponding MRI images were imported into Inveon Research Workplace software (Siemens) and manually aligned. The target region was manually drawn based on anatomical references, and numerical values (Bq / ml) were extracted from the corresponding PET images. Tracer uptake was calculated as the percentage of the injection volume per cubic centimeter (%ID / cc).
[0102] To perform autoradiography, tumors were embedded in an optimal cutting temperature compound (Tissue-Tech® OCT, Sakura FineTech, Netherlands, Alfen Ahn den Reing) and frozen at -20°C using a cryotome (Leica, Germany, Wetzlar). Next, 20 μm frozen sections were mounted on microscope slides (SuperFrost® Plus, R. Langenbrinck, Germany, Emendingen). The slides were exposed overnight to a fluorescence screen (Molecular Dynamics, a subsidiary of GE Healthcare). The fluorescence screen was then scanned with a fluorescence imager (Storm 840, Amersham, a subsidiary of GE Healthcare). The signal intensity of the sections was normalized based on the attenuated dose administered to rats using ImageJ, open-source software (National Institutes of Health, Bethesda, Maryland, USA).
[0103] Hematoxylin and eosin (H&E) staining was performed on autoradiographic sections using an automated staining system by staff from the dermatology department (University Hospital Tübingen, Germany).
[0104] Immunohistochemical analysis (IHC) was performed by staff from the Department of Pathology (University Hospital Tübingen, Germany) using an automated immunohistochemical staining system (Ventana Medical Systems, Roche) in accordance with the manufacturer's protocol.

[0169] Example 6 In Example 6, with reference to Figure 1, a model experiment using a non-radioactive tracer is disclosed to verify the self-destructive mechanism.
[0170] The model substrate shown on the left side of Figure 1A was incubated with β-galactosidase. The substrate was hydrolyzed by the enzyme to produce a primary metabolite, which then spontaneously decomposed to produce a quinone methide and a readily detectable colored metabolite (4-nitrophenol). More specifically, Figure 1A shows a schematic diagram of the enzymatic reaction. Figure 1B shows the HPLC of the unreacted substrate. Figure 1C shows the HPLC after incubation of the enzyme and substrate for 30 minutes, indicating that readily detectable p-nitrophenol (4NP) was obtained as a metabolite. Figure 1D shows the reference HPLC of 4NP. 4NP can be detected by measuring absorption at a wavelength of 320 nm.
[0171] Example 7 Figure 2 shows the uptake experiment in cells overexpressing β-galactosidase (BG).
[0172] In vitro experiments were performed by quantifying uptake using a gamma counter. In all experiments, 1 million cells of each cell line were treated with 20 μCi of the tracer. After incubation for 40 minutes, the cells were centrifuged, the supernatant was removed, and the cell pellet was resuspended in fresh PBS. Next, each sample was placed in a biodistribution tube and measured with a gamma counter. Each tracer was first tested using a β-galactosidase (LacZ) overexpression model of colorectal cancer cell lines (CT26-CL25) and wild-type cells (CT26) as a control (Figure 2A). Next, each tracer was tested in a senescent cell model, i.e., a hepatoma cell line (Amp19) treated with a ribosome checkpoint inhibitor (RCI) (Figures 2B and 2C).
[0173] Example 8 Example 8 shows an uptake experiment in a senescent cell model.
[0174] Referring to Figures 3A and 3B, the results of the in vitro evaluation of the novel tracer in the aging model are summarized in Table 1 below.
[0175] [Table 1]
[0176] In the in vivo experiment, aging was induced in in vivo Amp19 mouse xenografts by treatment with a ribosome checkpoint inhibitor. In the control group, mice were treated with a solvent (PBS). After induction of aging, a tracer (13 MBq) was intravenously injected, and dynamic PET and dynamic MRI scans were performed. Ex vivo tumor sections were subjected to autoradiography, X-Gal staining, and immunohistochemical analysis (H&E, p53, p21, and ki-67).
[0177] Example 9 In Example 9, [ 18Dynamic PET scans were performed on Amp19 tumor-bearing mice using F]TFPBGal (Figure 4). In CX-treated (senescent) tumors, [ 18 Dynamic uptake of [F]TFPBGal was higher at all time points compared to the untreated control. Uptake was stable in both treated and untreated tumors, reaching a maximum value and then plateauing, with no washout effect observed.
[0178] Referring to Figure 5, [ 18 Autoradiography of CX-treated (aging) Amp19 tumors and control Amp19 tumors after administration of F]PIPGal is shown. Amp19 tumor-carrying mice [ 18 Autoradiography was performed after administration of [F]PIPGal. Higher signal accumulation was observed in CX-treated (aging) tumors compared to non-aging controls.
[0179] Autoradiography of tumors (Figure 5) shows increased uptake in CX-treated (aging) tumors after PET scan compared to untreated controls.
[0180] Furthermore, the tumors were analyzed using conventional H&E staining. In addition, immunohistochemical analysis (IHC) for Ki67, activated caspase 3, p53, p21, and CD31 was performed on all samples.
[0181] According to the pathology report, the control tumors showed more necrosis, higher growth rate and apoptosis rate, fewer p21-positive and p53-positive cells, and more blood vessels compared to the aging tumors.
[0182] Ex vivo immunohistochemical analyses of CX-treated (aging) Amp19 tumors and solvent-treated (control) Amp19 tumors are shown in Figure 6 and Table 2.
