Description

Iodine isotope labeled benzyl phenyl ether derivative, preparation method, pharmaceutical composition and application thereof
Technical Field
The invention discloses iodine radioisotope labeled benzyl phenyl ether derivatives, a preparation method thereof, a pharmaceutical composition and application. In particular to benzyl phenyl ether derivatives shown in a general formula I, medicinal salts thereof, stereoisomers thereof, a preparation method thereof, a composition containing one or more radioactive compounds and application of the radioactive compounds in human or animal bodies as PD-L1 tracers in diagnosis and treatment of diseases related to PD-1/PD-L1 signal pathways, such as cancers, infectious diseases and autoimmune diseases.
Background
With the deep research on tumor immunity, people find that the tumor microenvironment can protect tumor cells from being recognized and killed by the immune system of the body, and the immune escape of the tumor cells plays a very important role in the occurrence and development of tumors. The Science journal of 2013 lists tumor immunotherapy as the first major breakthrough, and once again, immunotherapy becomes the focus of the tumor therapy field. The activation or inhibition of immune cells in the body is regulated by positive signals and negative signals, wherein programmed death molecule 1 (PD-1) ligand (PD-1 ligand, PD-L1) is a negative immune regulation signal, inhibits the immune activity of tumor-specific CD8+ T cells, and mediates immune escape.
The tumor cells have the ability to evade the immune system by binding the PD-L1 protein produced on their surface to the PD-1 protein of T cells. The tumor microenvironment in the body can induce infiltrated T cells to highly express PD-1 molecules, and the tumor cells can highly express ligands PD-L1 and PD-L2 of PD-1, so that PD-1 channels in the tumor microenvironment are continuously activated, and the function of the T cells is inhibited, so that the tumor cannot be found, and the treatment which needs to attack the tumor and kill the tumor cells cannot be sent to the immune system. The PD-1 antibody is an antibody protein directed against PD-1 or PD-L1, such that the first two proteins cannot bind, blocking this pathway, partially restoring T cell function, allowing these cells to continue killing tumor cells.
Immunotherapy based on PD-1/PD-L1 is a new generation immunotherapy which is currently spotlighted, aims to resist tumors by utilizing the human body's own immune system, induces apoptosis by blocking the PD-1/PD-L1 signal pathway, and has the potential of treating various types of tumors. Recently, a series of surprising research results prove that the PD-l/PD-Ll inhibitory antibody has strong antitumor activity on various tumors and is particularly attractive. Currently, 2 PD-1 mab drugs (Nivolumab and Pembrolizumab), 3 PD-L1 mab drugs (Atezolizumab, Durvalumab and Avelumab) are successively approved on the market [3], show excellent and relatively long-lasting efficacy in various malignancies such as lymphoma, melanoma, non-small cell lung cancer, kidney cancer, bladder cancer, etc., prolong the overall survival of patients, improve quality of life, and even enable individual patients to achieve cure [4], although immunotherapy is considered as a breakthrough therapy against cancer, and immune checkpoint inhibitors represented by PD-1/PD-L1 antibodies have become "star drugs" for cancer immunotherapy. However, the PD-1/PD-L1 antibody also has a number of disadvantages, mainly low response rates, such as: the overall response rate of PD-1/PD-L1 inhibitors is currently only 20-30% [5 ]. Still 70-80% of patients do not benefit, resulting in a waste of money, manpower and time. How to accurately screen effective tumor patients, how to accurately and effectively realize early diagnosis of tumors, effectively perform personalized treatment on the tumors, and simultaneously can minimize side effects of diagnosis and treatment, is a medical diagnosis and treatment method expected by people, namely accurate diagnosis and treatment, and the achievement of accurate medical treatment is an important subject of clinical research at present. The novel molecular diagnosis and treatment agent integrating diagnosis and treatment functions is one of the most effective solutions for realizing the aim of accurate diagnosis and treatment.
The precise diagnosis and treatment needs to adopt a high-sensitivity molecular imaging probe and an imaging technology to realize the rapid and precise diagnosis of a certain specific disease, and the targeted transportation and the controllable release of the medicine are adopted to ensure that the medicine can directly reach the focus without influencing normal organs. Around the important requirements of accurate imaging diagnosis, accurate treatment and prognosis evaluation of tumors, the key technologies of molecular imaging probes, targeted drugs and the like with high sensitivity, high specificity and high resolution are developed, and the key problems of accurate molecular image identification of tumor cells, accurate targeted tumor administration and molecular image evaluation are researched and solved. Single-Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) are two CT techniques of nuclear medicine, and are collectively called Emission Computed Tomography (ECT) because they image gamma rays emitted from a patient. At present, single SPECT imaging is gradually replaced by SPECT/CT, and the SPECT/CT becomes one of the most advanced medical imaging devices of human beings at present, and is an ideal tool for diagnosing living diseases and researching and developing new drugs. Advanced medical devices can measure biological activities of cells and molecules by using a SPECT principle, such as a SPECT system of GE company, and a composite imaging device SPECT & CT and PET & CT system combining diagnosis-level multi-layer CT, and can accurately locate the position, the nature and the degree of a lesion. SPECT imaging plays an important role clinically, and a three-dimensional image is obtained through tomography. The PET detection system has the advantages of high sensitivity, high resolution, tissue accumulation which can be properly quantified and the like, and can be combined with the anatomical image of CT or MR to display the biomolecular metabolism, the receptor ligand specific binding, the nerve medium activity and the like in vitro in a noninvasive, quantitative and dynamic manner.
The development of a molecular imaging probe with high sensitivity, high specificity and high resolution is a prerequisite for accurate diagnosis and treatment. The immunotherapy based on PD1/PD-L1 has low response rate, how to accurately screen effective tumor patients, and the acquisition of PD-L1 radioligand with high sensitivity, high specificity and high resolution is very important as a molecular imaging probe for monitoring the expression state of PD-L1 in tumor tissues. Currently, the evaluation of PD-L1 expression is usually performed by immunohistochemical method on tumor tissue biopsy specimens, which is very likely to result in inaccurate results and long time due to tumor tissue heterogeneity, and may cause local tissue damage and even tumor spread. The detection by the PD-L1 radioactive ligand through SPECT-CT is a non-invasive systemic detection means, can carry out tandem imaging on in-situ tumors, metastatic tumors and other PD-L1 expression tissues, and can timely monitor the dynamic change of PD-L1 expression in the tumor environment before, during and after the administration of the immune checkpoint regulator. In addition, several classes of molecular imaging agents based on antibody targeting to PD-L1 have been reported that provide sufficient affinity and specificity to PD-L1 to maximize the background ratio of signal, visualizing molecular targets within the tumor microenvironment. However, a drawback of antibody-based targeted PD-L1 imaging agents is slow clearance in vivo, particularly where elimination of the antibody imaging agent through the hepatobiliary system takes days to weeks, affecting imaging of adjacent organs such as the lung. As a result, it may take days to adequately clear the target tissue or adjacent tissue for imaging. An ideal PD-L1 radioligand for imaging requires high uptake in PD-L1 expressing tumors, but low background signal in non-PD-L1 expressing tissues, and should enable imaging of patients on the same day for clinical study design flexibility. Therefore, the PD-L1 radioligand based on small molecule targeting is probably an ideal imaging agent and has not been reported at present.

Said R1、R2、R3Y, X, as defined in any one of claims 1 to 35.
In addition, the starting materials and intermediates in the above reactions are readily available, and the reactions in each step can be readily synthesized according to reported literature or by conventional methods in organic synthesis to those skilled in the art. The compounds of formula I may exist in the form of solvates or non-solvates, and crystallization using different solvents may give different solvates. Pharmaceutically acceptable salts according to formula I include the different acid addition salts, such as the acid addition salts of the following inorganic or organic acids: hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, methanesulfonic acid, p-toluenesulfonic acid, trifluoroacetic acid, lycinic acid, maleic acid, tartaric acid, fumaric acid, citric acid, lactic acid. The pharmaceutically acceptable salts of formula I also include salts of various alkali metal (lithium, sodium, potassium), alkaline earth metal (calcium, magnesium) and ammonium salts, and salts of organic bases which provide physiologically acceptable cations, such as methylamine, dimethylamine, trimethylamine, piperidine, morpholine and tris (2-hydroxyethyl) amine. All such salts within the scope of the present invention may be prepared by conventional methods. During the preparation of the compounds of formula I and solvates and salts thereof, different crystallization conditions may occur as polycrystals or co-crystals.
In a third aspect of the present invention, a pharmaceutical composition is provided
The pharmaceutical composition comprises the iodine radioisotope labeled benzyl phenyl ether derivative as an effective component, and stereoisomers, pharmaceutically acceptable salts, pharmaceutically acceptable carriers or excipients, auxiliaries and diluents thereof.
The invention also relates to a pharmaceutical composition using the compound as an active ingredient. The pharmaceutical composition may be prepared according to art-recognized methods. The compounds of the invention may be formulated into any dosage form suitable for human or animal use by combining them with one or more pharmaceutically acceptable solid or liquid excipients and/or adjuvants.
The pharmaceutical compositions of the present invention may optionally further comprise additional components, such as antimicrobial preservatives, pH adjusting agents or fillers. Antimicrobial preservatives refer to agents that inhibit the growth of potentially harmful microorganisms such as bacteria, yeast or mold. Antimicrobial preservatives may also exhibit some bactericidal properties, depending on the dosage. The primary effect of the antimicrobial preservative of the present invention is to inhibit the growth of any such microorganisms in the radiopharmaceutical composition. Suitable antimicrobial preservatives include parabens, i.e. methyl, ethyl, propyl or butyl parabens or mixtures thereof; benzyl alcohol; phenol; cresol; cetrimide and thimerosal. A preferred antimicrobial preservative is paraben. A pH modifier refers to a compound or mixture of compounds that can be used to ensure that the pH of the radiopharmaceutical composition is within acceptable limits (about pH 40 to 8.5) for administration to humans or lactating animals. Suitable such pH adjusting agents include pharmaceutically acceptable buffers such as tricine, phosphate buffer or TRIS [ i.e. TRIS (hydroxymethyl) aminomethane ], and pharmaceutically acceptable bases. Bulking agents refer to pharmaceutically acceptable bulking agents that can facilitate handling of the starting material during product preparation, suitable bulking agents include inorganic salts such as sodium chloride, and water soluble sugars or sugar alcohols such as sucrose, maltose, mannitol, or trehalose.
Where the iodine radioisotope bonded phenyl group has one or more activating groups, to prevent deiodination, the pharmaceutical composition of the present invention may therefore require a stabilizing agent. A stabilizer refers to a compound that inhibits decomposition reactions such as redox reactions by trapping highly reactive free radicals such as oxygen-containing radicals generated by the radiolysis of water. The stabiliser of the invention is suitably selected from classical radical scavengers such as ascorbic acid or gentisic acid.
In addition, the biocompatible carrier medium is a fluid, especially a liquid, in which the labeled synthetic compound is suspended or dissolved so that the composition is physiologically tolerable, i.e., can be administered to a mammalian body without toxicity or undue discomfort. Biocompatible carrier media are injectable carrier liquids, such as sterile, pyrogen-free water for injection;aqueous solutions such as physiological saline (which may preferably be a balanced solution so that the final injectable product is isotonic or non-hypotonic); an aqueous solution of one or more tonicity-adjusting substances (e.g., salts of plasma cations with biocompatible counterions), sugars (e.g., prodrug sugars or sucrose), sugar alcohols (e.g., sorbitol or mannitol), glycols (e.g., glycerol), or other non-ionic polyol substances (e.g., polyethylene glycol, propylene glycol, etc.). The biocompatible carrier medium may also comprise a biocompatible organic solvent such as ethanol. Such solvents can be used to solubilize more lipophilic compounds or formulations. Preferably, the biocompatible carrier medium is pyrogen-free water for injection, isotonic saline or aqueous ethanol. Such an aqueous ethanol solution may have a range of compositions, but preferably 5-10% ethanol for the dry final composition, as described above, the pH of the biocompatible carrier medium for intravenous injection is suitably 4.0 to 10.5 for the present invention123The ph of the I-labelled radiopharmaceutical, the biocompatible carrier medium, is suitably from 4.5 to 8.5, preferably from 4.6 to 8.0, most preferably from 5.0 to 7.5.
The radiopharmaceutical compositions of the present invention are provided in a clinical grade syringe or container equipped with a seal (e.g., a screw-on septum cap) suitable for single or multiple punctures with a hypodermic needle while maintaining sterile integrity, such containers may include single or multiple doses. Suitable containers include sealed containers that allow for maintaining sterility integrity and/or radiological safety while allowing for entry and withdrawal of solutions through a syringe, with preferred containers being septum-sealed vials in which an air-tight cap is screwed on with a overseal (typically aluminum). An additional advantage of such a container is that the closure can withstand a vacuum if desired, for example to change headspace gas or degassed solution. When the radiopharmaceutical is provided in a multi-dose container, it is preferred that such container comprises a single volume vial (e.g. a 10 to 30cm3 volume vial). The vial contains sufficient radiopharmaceutical for multiple patient doses. Unit patient doses can therefore be drawn into clinical grade syringes at various time intervals during the life of the bulk vial formulation to accommodate the clinical condition.
Thus, a radiopharmaceutical syringe designed to contain a single human dose or "unit dose" is preferably a disposable syringe or other syringe suitable for clinical use. Such syringes may optionally be equipped with a syringe shield to protect the operator from the radioactive dose. Such radiopharmaceutical syringe shields are known in the art and are commercially available in a variety of designs, preferably comprising lead or tungsten.
The fourth aspect of the technical scheme of the invention provides an application of iodine radioisotope labeled benzyl phenyl ether derivatives, stereoisomers and pharmaceutically acceptable salts thereof in preparation of medicines for diagnosing and treating diseases related to PD-1/PD-L1 signal pathways.
The diagnosis and treatment comprises diagnosis and treatment, wherein the diagnosis refers to that the iodine radioisotope-labeled benzyl phenyl ether derivative is used as a PD-L1 protein probe, and the SEPCT, PET or SEPCT-CT and PET-CT instruments are used for detecting or monitoring the expression states of lesion tissues and normal tissues PD-L1 in a patient body, so that the diagnosis and treatment system is applied to disease diagnosis, patient screening, treatment prognosis evaluation and disease progress, the metabolism condition in the drug body is observed, and reliable information is provided for the effective treatment of diseases by the drug; the treatment refers to that the iodine radioisotope labeled benzyl phenyl ether derivative is a PD-L1 inhibitor and is also a tumor immunotherapy agent, the radioactivity of the iodine radioisotope labeled benzyl phenyl ether derivative can kill tumor cells while being combined with PD-L1 in tumor tissues, and the tumor immunotherapy effect can be improved if the iodine radioisotope labeled benzyl phenyl ether derivative and the PD-L1 can be cooperated with immunotherapy.
The diseases related to the PD-1/PD-L1 signal channel are selected from cancers, infectious diseases and autoimmune diseases. The cancer is selected from skin cancer, lung cancer, urinary system tumor, blood tumor, breast cancer, glioma, digestive system tumor, reproductive system tumor, lymphoma, nervous system tumor, brain tumor, and head and neck cancer. The infectious diseases are selected from bacterial infection and virus infection. The autoimmune disease is selected from organ-specific autoimmune diseases and systemic autoimmune diseases, wherein the organ-specific autoimmune diseases comprise chronic lymphocytic thyroiditis, hyperthyroidism, insulin-dependent diabetes mellitus, myasthenia gravis, ulcerative colitis, pernicious anemia with chronic atrophic gastritis, goodpasture's syndrome, primary biliary cirrhosis, multiple sclerosis and acute idiopathic polyneuritis, and the systemic autoimmune diseases comprise rheumatoid arthritis, systemic lupus erythematosus, systemic vasculitis, scleroderma, pemphigus, dermatomyositis, mixed connective tissue disease and autoimmune hemolytic anemia.
The beneficial technical effects are as follows:
the iodine radioisotope labeled benzyl phenyl ether derivative has high inhibitory activity on the interaction of PD-1/PD-L1 and strong binding capacity with PD-L1 protein; and has a longer physiological half-life in vivo and higher stability in plasma; the preparation method has short synthesis time and high radiochemical yield; in the application aspect, the PD-L1 protein micromolecule probe has high sensitivity and specificity, and can be used for detecting or monitoring the expression states of lesion tissues and normal tissues PD-L1 in a patient body by utilizing SEPCT, PET or SEPCT-CT and PET-CT instruments and equipment, is applied to disease diagnosis, patient screening, treatment prognosis evaluation and disease progress, observes the metabolism condition in the body of a medicament, and provides reliable information for the medicament to effectively treat diseases; the iodine radioisotope labeled benzyl phenyl ether derivative is a PD-L1 inhibitor and is also a tumor immunotherapy agent, the radioactivity of the derivative has a killing effect on tumor cells, and radiotherapy and immunotherapy are synergistic, so that the tumor immunotherapy effect can be improved. Therefore, the iodine radioisotope labeled benzyl phenyl ether derivative can be used as a small molecule imaging agent of PD-L1 protein with integrated diagnosis and treatment.
