Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical technology, and in particular to a carbonic anhydrase-targeted radiopharmaceutical. Background Art
[0002] There are many types of α-carbonic anhydrases (α-CAs) distributed in most organs and tissues of the human body, and one type of CA is dominant in some organs and tissues. CAIX / XII is dominant in most hypoxic solid tumors, and CAI / II is one of the main protein components of red blood cells in the blood. Tumor-specifically expressed CAIX / XII is a type of transmembrane protein. CAIX is stably expressed in tumors such as RCC (renal cell carcinoma). CAIX is not expressed in normal kidney tissue, and is only partially weakly expressed in organs and tissues other than kidney tissue. Therefore, CAIX is a potential excellent target for the diagnosis and treatment of ccRCC (renal clear cell carcinoma). CAIX is also overexpressed in many other types of tumors, such as lung cancer, colorectal cancer, gastric cancer, pancreatic cancer, melanoma, breast cancer, cervical cancer, bladder cancer, ovarian cancer, brain cancer, head and neck cancer, astrocytoma, oral cancer, etc.
[0003] Tumor-overexpressed CAIX can catalyze the hydration reaction of carbon dioxide, converting carbon dioxide into bicarbonate ions and protons, and regulating the pH of the cell environment. The increased acidity of the local microenvironment of the cell can activate the VEGF signaling pathway, promote new angiogenesis, and play an important role in the occurrence and development of tumors. In addition, most CA-targeted inhibitors bind to the metal active center of the CAIX extracellular enzyme catalytic domain to block its catalytic activity. The structure of CAIX-specific inhibitors is mostly based on the sulfonamide structure, with ionization, hypoxia-activated structuring, glycosylation, and nanoparticle inclusion. The labeling of small molecules of CAIX inhibitors with nuclides can be used for the treatment and diagnosis of tumors.
[0004] Currently, the effective treatment for RCC is surgical resection, but the limitation of surgery is that the recurrence rate is 30% (or about 50%) 5 years after surgery, and surgery is not possible for advanced or metastatic RCC. The classic effective drug for metastatic RCC is high-dose interleukin 2, but it can only produce a sustained complete response in 7-10% of patients. Therefore, for patients with a high risk of recurrence, the development of more sensitive and accurate early diagnosis strategies, as well as effective systemic therapeutic drugs for advanced and metastatic RCC, is a challenge that needs to be continued and resolved. The development of better CAIX targeted drugs and CAIX inhibitors with high affinity and specificity for the treatment of tumors has important scientific research value and broad application prospects.

[0456] CAIX (purchased from ACROBiosystems Inc, 0.5 mg / mL) was coupled to the surface of the CM5 chip, and the sample molecules were diluted with running buffer (HBS-EP buffer) (10 mM HEPES, 150 mM NaCl, 3 mM EDTA, 0.05% (v / v) Surfactant P20 (Tween20)), 5% DMSO, pH 7.4). The sample was diluted with a series of different concentrations of the sample solution in equal proportion by DMSO solvent (dilution ratio: 2), and the sample was injected and the affinity of the sample to CAIX was measured. The affinity of the sample NYM045 / 046 / 047 / 048 / 049 / 050 / 070 / 071 / 073 / 074 to CAIX is represented by the equilibrium dissociation constant KD (Kd / Ka) value, where Kd is the dissociation constant and Ka is the binding constant. The smaller the KD value, the higher the affinity of the compound to the protein. The test results are shown in Table 1 below. It was found that among the tested compounds, NYM046, NYM048, NYM049, NYM050, NYM070, NYM071, NYM073, and NYM074 showed low nanomolar affinity for CA9 and had a strong affinity for CA9.

Static scans were performed at 1, 2, and 3 hours after administration. Scan images were obtained after reconstruction by the device software. The scan images are shown in the attached figure. Figures 33-38 As shown, the scanned image is analyzed.
[0467] As attached Fig.33 As shown, 68 One hour after administration, Ga-NYM045 showed high radioactivity uptake in the tumor, but not in other normal tissues. 68 Ga-NYM045 drug is rapidly excreted through the kidneys; Fig.34 As shown, 68 One hour after administration of Ga-NYM046, it was found that the radioactive uptake of the drug was obvious in the tumor and maintained at a high level for 3 hours without a significant downward trend. 68 Ga-NYM046 drug can be absorbed for a long time in tumors or metastases; Fig.36 As shown, 68 One hour after administration of Ga-NYM048, it was found that its uptake in the tumor was obvious. Until 3 hours, the uptake value did not change significantly, with no obvious increase or decrease trend. In other organs, the uptake gradually decreased, and in normal tissues, the uptake 68 Ga-NYM048 drug can be rapidly excreted through the kidneys; Fig.37 As shown, 68 One hour after administration of Ga-NYM049, it was found that its uptake in the tumor was obvious, and the uptake value did not change significantly until 3 hours, with no obvious increase or decrease trend, while the uptake in other normal tissues gradually decreased; as shown in the attached Fig.38 As shown, 68 One hour after administration of Ga-NYM050, it was found that its uptake value in the tumor was obvious. Until 3 hours, the uptake value did not change much, with no obvious increase or decrease trend. However, the uptake in other organs gradually decreased, and the uptake in normal tissues was 68Ga-NYM050 is rapidly excreted by the kidneys.
[0468] Changes in tumor radioactivity uptake are shown in the attached Fig.39 As shown, 68 Ga-NYM046, 68 Ga-NYM048, 68 Ga-NYM049, 68 One hour after administration, Ga-NYM050 drug can be rapidly enriched in the tumor and has high uptake at the tumor location; the high uptake can be maintained for 3 hours, while the uptake in other non-target organs gradually decreases.
[0469] 3. Mouse model: The experimental mice were purchased from Shanghai Runnuo Biotechnology Co., Ltd. The mouse model was an OS-RC-2 tumor subcutaneous heterotopic transplant model established based on BALB / c nude mice, which is a mouse model constructed with human renal cancer cells.
[0470] The experimental steps are as follows:
[0471] Two mice were selected and each mouse was given 68 Ga-NYM07480μCi, the animals were subjected to dynamic scanning with MicroPET / CT (SNPC-303 SuperNova, Pingsheng Medical Technology (Kunshan) Co., Ltd.) 1h after administration, and static scanning was performed 2h after administration. The scanned images were reconstructed by the equipment software and analyzed.
[0472] The experimental results of tumor drug uptake are shown in the attached Fig.40 As shown (the arrow indicates the tumor uptake), 68 Ga-NYM074 can quickly accumulate at the tumor site, and 1 hour after drug injection, the tumor-background uptake ratio is high, and significant drug uptake can be seen at the tumor. 2 hours after administration, the tumor still maintains high uptake.
[0473] The experimental results of drug uptake by various tissues are shown in the attached Fig.41 and 42 As shown, the data results of the ratio of tumor tissue uptake to non-target organ uptake show that 68 The ratio of Ga-NYM074 uptake in tumors to muscle in mice gradually increased over time, and it has potential value as an imaging agent in the diagnosis of tumor diseases.
[0474] Embodiment 5: 68 Ga-NYM050OS-RC-2 model competitive inhibition experiment
[0475] 1. Experimental mice were purchased from Shanghai Runnuo Biotechnology Co., Ltd. The mouse model was an OS-RC-2 tumor subcutaneous heterotopic transplant model established based on BALB / c nude mice, which is a mouse model constructed with human renal cancer cells.
[0476] The experimental steps are as follows:
[0477] The experiment was divided into two parts: one baseline experiment and one blocking experiment.
[0478] Four mice were selected for the baseline experiment, and each mouse was given 68 Ga-NYM050 drug 80Ci, mice were scanned by MicroPET / CT at 0.5h, 1h, and 2h after administration, and the scanned images were obtained after reconstruction by the equipment software. The scanned images were analyzed and the experimental results are shown in the attached Fig.43 , 45 shown.
[0479] On the second day of the baseline experiment, the blocking experiment used the same animals as the baseline experiment. Each mouse was first given NYM050 at an injection dose of 68 40 times the weight of Ga-NYM050 drug; injected 1 hour after NYM050 68 Ga-NYM050 80μCi, and MicroPET / CT scans were performed at 0.5h, 1h, 2h, and 3h after administration. Scanned images were obtained after reconstruction by the equipment software and analyzed. The experimental results are shown in the attached Fig.44 , 46 shown.
[0480] It can be seen that in the baseline experiment, the drug alone 68 After 1 hour of Ga-NYM050, it was found that it had clear imaging at the tumor site and there was no obvious downward trend within 2 hours; in the blocking experiment, the addition of NYM050 in advance could significantly block the tumor 68 The uptake of Ga-NYM050 confirmed 68 Ga-NYM050 is able to specifically recognize tumors.
[0481] Embodiment 6: 177 Lu-NYM073 / 177 Lu-NYM074 SPECT / CT scanning experiment in OS-RC-2 model
[0482] Mouse model: The experimental mice were purchased from Shanghai Runnuo Biotechnology Co., Ltd. The OS-RC-2 tumor subcutaneous heterotopic transplant model was established based on BALB / c nude mice. This model is a mouse model constructed with human renal cancer cells.
[0483] Experimental steps:
[0484] One animal model mouse was selected. Each animal was given 177 Lu-NYM073 / 177 The drug Lu-NYM074 was administered at 300 μCi, and SPECT / CT scans of small animals were performed at 4 h, 24 h, 48 h, 96 h, and 120 h after administration to obtain scanned images, which were then analyzed.
[0485] By the attached Fig.47 It can be seen that 177 Lu-NYM073 was enriched in the tumor (arrow in the figure) 4 hours after administration, and the uptake in normal tissues gradually decreased. 177 Lu-NYM074 was enriched in the tumor (arrow in the figure) 6 hours after administration, and the organ uptake in normal tissues gradually decreased; until 120 hours later, the target product was still taken up in the tumor, which shows that the retention time of this target product in the tumor is long, which is beneficial to the treatment of clinical tumor diseases, and the uptake of non-target organs is reduced and cleared quickly.
[0486] Example 7: Experimental study on the efficacy of the target product in model mice
[0487] Mouse model: The experimental mice were purchased from Shanghai Runnuo Biotechnology Co., Ltd. The OS-RC-2 tumor subcutaneous heterotopic transplant model was established based on BALB / c nude mice. This model is a mouse model constructed with human renal cancer cells.
[0488] Experimental steps:
[0489] Fifteen mice were randomly selected and divided into three groups, each with five mice, namely, saline group, single-dose group, and multiple-dose group. 177 Lu-NYM074 drug 2mCi, each mouse was given once, by tail vein injection; multiple groups were given to each animal 177 Lu-NYM074 was administered twice, 2 mCi each time, seven days apart, by tail vein injection; the weight and tumor volume of mice were measured before the experiment, and every three days after administration. The long and short diameters of the tumor were measured to calculate the tumor volume, and the calculation formula is as follows: tumor volume (TV) = a × b 2 / 2 (a is the long diameter, b is the short diameter), and the tumor growth inhibition rate TGI was calculated.
[0490] 33 days and 40 days after administration, the TGI values of the single-dose group were 33.4% and 24.8%, respectively, and the TGI values of the multiple-dose group were 76.2% and 72.9%, respectively. Fig.48It can be seen that compared with the saline group, the single and multiple groups showed significant anti-tumor activity and could significantly control tumor growth. The tumor growth in the multiple groups was slower, showing the dependence of tumor on drug dose. In the three groups of experiments, the weight change trend of mice was slightly different between groups, as shown in the attached Fig.49 As shown, it can be seen that this drug has good anti-tumor efficacy and good safety.
