Description

Technical Field

[0001] The present disclosure relates to prostate-specific membrane antigen (PSMA) ligands. In particular, the present disclosure relates to PSMA ligands having a glycine-urea-lysine (GUL) component, a radioisotope, and a chelating agent that can include a radioactive metal.

[0002] The present disclosure also relates to the use of these compounds in the imaging diagnosis and treatment of prostate cancer.

Background Art

[0003] Theragnostics is a patient management strategy that encompasses the integration of diagnostic and therapeutic methods.

[0004] In the context of nuclear medicine, theragnostics refers to the use of molecular target molecules labeled with diagnostic radioactive metals (e.g., positron or gamma emitters) or therapeutic radioactive metals (e.g., beta emitters) for the diagnosis and therapy of specific diseases. The most developed approach is based on radiolabeling target molecules with high affinity for receptors expressed on tumor cells with gallium Ga-68 for diagnostic purposes or lutetium Lu-177 for therapeutic purposes. Thus, following molecular imaging diagnosis and disease diagnosis, individualized treatment using the same molecular target compound can be effectively performed.

[0005] This is because it allows for the selection of therapies or different treatment approaches, as well as follow-up surveys after treatment. ru.

[0006] For patients, theragnostics ultimately result in more effective medical care and eliminate unnecessary treatments. Reduce or eliminate treatment, and tailor therapeutic interventions to the patients who will benefit the most. It is possible that the patient may not respond to unnecessary treatment, or otherwise experience side effects. By predicting which patients will experience this condition, the theragnostic approach is efficient. It's not just about being patient-centered, but also about being patient-centered.

[0007] For physicians, theragnostics is the optimal therapy for diagnosing and staging diseases. To select, as well as to monitor treatment effectiveness and disease progression, to improve one's own abilities and health To improve the above outcomes, we can safely and effectively improve predictive capabilities. ru.

[0008] For payers, the theragnostic approach is not the optimal diagnostic and therapeutic method. To reduce associated costs and shorten the time required for diagnosis, and to provide effective individualized treatment plans. It can treat patients.

[0009] Prostate cancer is one of the most widespread cancers in the United States and Europe. In particular, metastatic pre-prostate cancer is common. Prostate carcinoma (mCRPC) is associated with a poor prognosis and a reduced quality of life.

[0010] Recently, PSMA ligand-based internal radiotherapy (endo-radiotherapy) has been gaining popularity. rapy) is an example of a new development trend in the treatment of prostate cancer, PSM A is overexpressed in primary cancer lesions and in soft tissue / bone metastatic diseases, therefore It is considered a suitable target for imaging diagnosis and therapy. Furthermore, PSMA expression is associated with disease. This appears to be even more pronounced in the castration-resistant variant, which is the most malignant of the variants. This is a typical example of a patient population with high medical needs that has not yet been addressed (March al et al.,Histol Histopathol,2004,Jul;19 (3):715-8;Mease et al.,Curr Top Med Chem ,2013,13(8):951-62).

[0011] Among the many small molecule ligands that target PSMA, urea-based low-molecular-weight active agents are These were the most extensively investigated. These active ingredients were used in the clinical evaluation and PR of prostate cancer. It has been shown to be suitable for RT therapy. Some of these active ingredients are used as target scaffolds. It contains glutamate-urea-lysine (GUL).

[0012] Some radiolabeled small molecule inhibitors of PSMA were designed using this as a starting point (K iess AP,Banerjee SR,Mease RC,et al.Prost ate-specific membrane antigen as a target t for cancer imaging and therapy.QJ Nuc l Med Mol Imaging.2015;59:241-268)

[0013] However, in certain circumstances, the use of radioactive metals for diagnostic purposes may be limited (6 (Problems arising from the availability of 8Ga and the fragmentation of its production.)

[0014] On the other hand, 68Ga has a physical half-life of only 68 minutes. Therefore, 68Ga- PSMA-PET scans are preferably performed in-house and with sufficient tracer radioactivity. Delivery to remote centers is difficult. As a result, large-scale facilities with many patients The center requires production several times a day, or the simultaneous operation of multiple production machines. It requires movement, which increases costs. Meeting the quantitative demand for such centers... To overcome these limitations, the use of 18F-labeled PSMA tracers is also possible. Good. A PET radiopharmaceutical pharmacy with a cyclotron on site (radiophar Macy can produce highly radioactive 18F at an affordable cost. 18F labeling The physical half-life of PSMA tracers (110 minutes) is also a factor in the centralization of production and remote satellites. This could enable delivery to the light center. 18F also has a lower positron energy than 68Ga. It has energy (0.65 vs. 1.90 MeV) and theoretically leads to an improvement in spatial resolution.

[0015] However, the development of alternative PSMA ligands is always desirable. The reason is that diagnostic methods... The development of a diverse range of alternative PSMA ligands suitable for use as both a therapeutic agent and / or treatment would be beneficial. Because it could become that.
