Description

[Technical Field]

[0001] The present invention relates to the art of pharmaceuticals, and more particularly to tetracyclic compounds and their use. [Background technology]

[0002] Tumors are a common disease that seriously endangers human health, and malignant tumor mortality rates have been steadily increasing. Due to the heterogeneity of tumors, simply using the same treatment method or the same drug depending on its origin and pathological characteristics can easily lead to problems caused by inappropriate treatment, delaying the patient's crucial treatment time and timing. Therefore, there seems to be a great need to adopt precise treatment for various tumor situations. With the advancement of biological technology, tumors have a continuous genotype distribution at the molecular level, such as genes and proteins, and changes in the expression and activity of tumor-related genes and proteins are being discovered one after another. Changes in the expression and activity of tumor-related genes and proteins play an important role in the development of malignant tumors. The discovery and application of biomarkers provide precise guidance for the application of related drugs, enabling precise treatment of tumors, thereby achieving targeted drug delivery, significantly improving treatment efficacy, and reducing drug dosage and toxic side effects.

[0003] Therefore, developing drugs that can precisely treat tumors is an urgent task in this field of technology. [Overview of the Initiative] [Problems that the invention aims to solve]

[0560] DNA methylation DNA methylation is a form of chemical modification of DNA that alters gene expression without changing the DNA sequence. Numerous studies suggest that DNA methylation can regulate gene expression by altering chromatin structure, DNA morphology, DNA stability, and the way DNA interacts with proteins.

[0561] DNA methylation is one of the first and most deeply studied regulatory mechanisms of epigenetic inheritance. Broadly speaking, DNA methylation refers to a chemical modification process in which a specific base on a DNA sequence acquires a methyl group via covalent bonding with S-adenosylmethionine as the methyl donor, catalyzed by DNA methyltransferase 1. This DNA methylation modification can occur at sites such as the C-5 position of cytosine, the N-6 position of adenine, and the N-7 position of guanine. In general research, DNA methylation primarily refers to the process of methylation of the carbon atom at position 5 of cytosine in CpG dinucleotides. The product is called 5-methylcytosine (5-mC) and is the main form of DNA methylation in eukaryotes such as plants and animals. DNA methylation, as a relatively stable modification state, can be inherited by the DNA replication process under the action of DNA methyltransferases, thus playing an important role in regulating epigenetic inheritance.

[0562] DNA methylation reactions can be divided into two types. Type 1 involves the methylation of DNA that has two unmethylated strands and is called de novo methylation. Type 2 involves the methylation of one unmethylated strand of a double-stranded DNA that has one methylated strand and is called maintenance methylation.

[0563] Typically, DNA methylation is the methylation of DNA CpG sites. CpG dinucleotides are distributed very unevenly throughout the human genome, and some segments of the genome retain CpGs at a higher-than-normal rate. These are mainly CpG-enriched regions (also called CpG islands) located in gene promoters and exon regions, and some regions that enrich CpG dinucleotides, with more than 60% of gene promoters containing CpG islands. Here, CpG is an abbreviation for cytosine (C)-phosphate (p)-guanine (G).

[0564] Intracellular gene expression is regulated in various ways by signaling pathways, transcription factors, and epigenetic modifications. DNA methylation is an important method by which epigenetic modifications regulate gene expression. The level of DNA methylation in a specific gene region always affects the expression level of that gene. Compared to regulation of gene expression by signaling pathways and transcription factors, DNA methylation by epigenetic modifications has a more stable effect on gene expression and is less susceptible to the extracellular environment. Because DNA methylation can be easily detected with existing technologies, it is an ideal biomarker.

[0663] Example 14 We will investigate the activity of membrane-permeable transition pores in the related cells of the glomeruli. Experimental background: The mitochondrial permeability transition pore (abbreviated as mPTP) is a non-specific pathway on the inner mitochondrial membrane that allows small molecules with a molecular weight of less than 1.5 KD to pass freely. Its activity is affected by peroxides (such as H2O2), pH, and calcium ions inside the mitochondria. Some mitochondrial permeability transition pores are activated, while some are inactivated. For cells in which the mitochondrial permeability transition pore is activated, when peroxides (such as H2O2) are added, the activity of the mitochondrial permeability transition pore increases and the mitochondrial membrane potential decreases. In contrast, for cells in which the mitochondrial permeability transition pore is inactivated, when peroxides (such as H2O2) are added, it has no obvious effect on the activity of the mitochondrial permeability transition pore and does not cause an obvious change in the mitochondrial membrane potential. Based on this principle, we can determine whether mPTP is activated in specific cells by measuring the change in the mitochondrial membrane potential difference under the stimulation of peroxides.

[0664] Experimental methods and results: Daoy cells (human medulloblastoma, ATCC number HTB-186) were cultured in DMEM medium + P / S with 10% fetal bovine serum. The medium was supplemented with 1.5 μM of Cyclosporin A (abbreviated as CsA. CsA effectively suppresses the activity of the mPTP mitochondrial permeability transition pore), and at the same time, cells cultured without CsA were selected as the control group. When detecting the mitochondrial membrane potential difference with Tetramethylrhodamine (TMRM), the higher the TMRM fluorescence intensity, the greater the membrane potential difference. The results are shown in Table 3. S A (abbreviated as CsA. CsA S effectively suppresses the activity of the mPTP mitochondrial permeability transition pore) was added, and at the same time, cells cultured without CsA were selected as the control group. When detecting the mitochondrial membrane potential difference with Tetramethylrhodamine (TMRM), the higher the TMRM fluorescence intensity, the greater the membrane potential difference. The results are shown in Table 3. S effectively suppresses the activity of the mPTP mitochondrial permeability transition pore) was added, and at the same time, cells cultured without CsA were selected as the control group. When detecting the mitochondrial membrane potential difference with Tetramethylrhodamine (TMRM), the higher the TMRM fluorescence intensity, the greater the membrane potential difference. The results are shown in Table 3.

Table 3

[0665] As seen from Table 3, CsA SFor normal Daoy cells without A added to the culture medium, the membrane potential drops significantly under the action of H2O2, indicating that mPTPs in Daoy cells are activated. However, when activated C was added to the culture medium, the membrane permeable transition pores of the mPTP granules were also activated. S For Daoy cells A, adding H2O2 prevents their membrane potential from decreasing, and this is because activated mPTPs are C S This indicates that it is suppressed and inactive by A. In this case, the membrane potential does not decrease due to H2O2.

[0666] Therefore, as can be seen from Table 3, the membrane-permeable transition pores of the glomeruli in Daoy cells are activated.

[0667] Example 15 This study investigates the inhibitory effect of the compound of the present invention on the vitality of Daoy cells in which mPTP is normally activated, and on the vitality of Daoy cells in which mPTP formed by introducing PPIF mRNA shRNA is inactivated.

[0668] The English name for the term "peptidyl-prolyl isomerase F" is Peptidyl-prolyl cis-trans isomerase F, abbreviated as PPIF. Its protein number is UniProtKB / Swiss-Prot: P30405, and its gene number is NCBI Entrez Gene: 10105.

[0669] 1. Forms Daoy cells with reduced activation of the membrane permeable transition pore (mPTP) of the glomeruli. 1.1 Experimental Background: The activity of the membrane permeable transition pore (mPTP) of the glomeruli is regulated by the PPIF protein; therefore, suppressing the PPIF protein significantly reduces mPTP activity. Since the activity of the PPIF protein is controlled by the amount of PPIF protein expressed within the cell, introducing shRNA of specific induced degradation PPIF mRNA into Daoy cells specifically reduces the expression level of PPIF protein in Daoy cells, thereby forming Daoy cells in which the membrane permeable transition pore (mPTP) of the glomeruli is inactivated (abbreviated as Daoy cells with inactivated mPTP).

[0670] 1.2 Experimental Method and Results: A viral vector containing the shRNA of specifically induced degradation PPIF mRNA was obtained using cloning technology. The shRNA sequence (nucleotide sequence GTTCTTCATCTGCACCATAAA (SEQ ID NO: 2)) contained in this viral vector was subjected to specific induced degradation of PPIF mRNA. Daoy cells into which the gene was introduced into the viral vector containing the shRNA of specifically induced degradation PPIF mRNA were designated as the experimental group, and Daoy cells into which the gene was introduced into an empty viral vector without the shRNA of specifically induced degradation PPIF mRNA were designated as the control group. The expression level of PPIF protein in Daoy cells was detected by Western blotting, and the results are shown in Figure 1. As can be seen from Figure 1, Daoy cells into which the shRNA of specifically induced degradation PPIF mRNA was introduced hardly expressed PPIF (PPIF shRNA in Figure 1), while Daoy cells into which the shRNA of specifically induced degradation PPIF mRNA was not introduced expressed PPIF (Con shRNA in Figure 1, control group) normally. When the glomerular membrane potential difference was detected in Daoy cells into which a gene was introduced using an empty viral vector lacking the shRNA of specifically induced degradation PPIF mRNA, and in Daoy cells into which a gene was introduced using a viral vector containing the shRNA of specifically induced degradation PPIF mRNA, according to the method of Example 14, the TMRM fluorescence intensity increased and the membrane potential difference became larger. The results are shown in Table 4-5. [Table 4] [Table 5]

[0671] Table 4-5 shows that in Daoy cells into which the gene is introduced into an empty viral vector lacking the shRNA of specifically induced degradation PPIF mRNA, the membrane permeable transition pore (mPTP) of the glomeruli is activated. In Daoy cells into which the gene is introduced into a viral vector containing the shRNA of specifically induced degradation PPIF mRNA, the membrane permeable transition pore (mPTP) of the glomeruli is inactivated. By introducing the shRNA of specifically induced degradation PPIF mRNA into Daoy cells, we successfully create Daoy cells in which the membrane permeable transition pore (mPTP) of the glomeruli is inactivated.

[0672] Using the Promega CellTiter-Glo kit (which reflects cell vitality by examining intracellular ATP content), we detected the vitality of Daoy cells inactivated by mPTPs that had been introduced with shRNA for specific induced degradation of PPIF mRNA, and the vitality of Daoy cells activated by mPTPs that had not been introduced with shRNA for isomorphosis-induced degradation of PPIF mRNA. The results are shown in Figure 2. As can be seen from Figure 2, the vitality of Daoy cells inactivated by mPTPs that had been introduced with shRNA for specific induced degradation of PPIF mRNA and the vitality of Daoy cells activated by mPTPs that had not been introduced with shRNA for isomorphosis-induced degradation of PPIF mRNA are almost the same. There is no statistical significance in the difference in cell vitality.

[0673] 2. Investigate the relationship between the inhibitory effect of the compound of the present invention on cancer cells and mPTP activity. 2.1 Experimental Background: The Promega CellTiter-Glo kit reflects cell activity by directly measuring intracellular ATP content to detect cell vitality. This experiment investigated the inhibition of Daoy cell vitality by inactivating mPTPs that had been introduced with shRNA for specific induced degradation of PPIF mRNA, and by activating Daoy cell vitality by mPTPs that had not been introduced with shRNA for isomorphically induced degradation of PPIF mRNA. 50 Detect the value.

[0674] 2.2 Experimental Methods and Results: Daoy cells that inactivate mPTPs by introducing shRNA of specificity-induced degradation PPIF mRNA and Daoy cells that activate mPTPs by not introducing shRNA of isomorph-induced degradation PPIF mRNA were cultured in EMEM medium + P / S containing 10% fetal bovine serum. The semi-inhibitory concentration IC of the compound of the present invention for both types of cells was measured. 50 The following was measured. The results are shown in Table 6. [Table 6] Note: IC 50 This is the 50% inhibiting concentration, i.e., the concentration of the inhibitor that achieves a 50% inhibitory effect. Daoy cells that activate mPTP are Daoy cells into which the gene is introduced into an empty viral vector that does not have the shRNA of specifically induced degradation PPIF mRNA, and Daoy cells that inactivate mPTP are Daoy cells into which the gene is introduced into a viral vector that has the shRNA of specifically induced degradation PPIF mRNA.

[0675] As can be seen from Table 6, the compounds of the present invention achieve a significant inhibitory effect on Daoy cells that inactivate mPTP, but an insufficient inhibitory effect on Daoy cells that activate mPTP. In order to significantly enhance the inhibitory effect of the compounds of the present invention by lowering the mPTP activity of Daoy cells, the compounds of the present invention have a more significant inhibitory effect on Daoy cells that inactivate mPTP, and Daoy cells that inactivate mPTP are highly sensitive to the compounds of the present invention. As a result, the compounds of the present invention have an excellent refining therapeutic effect on Daoy cells that inactivate mPTP. As described above, when PPIF protein is suppressed, mPTP activity is significantly reduced. Suppressing the expression level of PPIF protein reduces the mPTP activity of Daoy cells. Therefore, the compounds of the present invention achieve a significant inhibitory effect on Daoy cells that lowly express PPIF protein, but an insufficient inhibitory effect on Daoy cells that normally express PPIF protein. As a result, lowering the expression level of PPIF protein may significantly enhance the inhibitory effect of the compounds of the present invention. Therefore, the compounds of the present invention exhibit a more significant inhibitory effect on Daoy cells that lowly express PPIF protein. In other words, Daoy cells that lowly express PPIF protein are more sensitive to the compounds of the present invention than Daoy cells that normally express PPIF protein. As a result, the compounds of the present invention exhibit an excellent refining therapeutic effect on Daoy cells that lowly express PPIF protein.

[0676] Example 16 In this example, we investigate the sensitivity of various compounds prepared in the example to the expression levels of NNMT and DNMT1 in NCI-H82 cells.

[0677] Experimental Methods and Results: NCI-H82 cells with high NNMT protein expression (ov-NNMT NCI-H82 cells) were obtained by introducing the NMT gene into NCI-H82 cells via a viral vector to overexpress the NNMT protein. NCI-H82 cells with low NMT protein expression (sh-DNMT1 NCI-H82 cells) were obtained by knocking down the expression of DNMT1 in NCI-H82 cells by introducing the gene into shRNA (the nucleotide sequence of the shRNA is GATCCGGGATGAGTCCATCAAGGAAGATTCAAGAGATCTTCCTTGATGGACTCATCCTTTTTTG) (SEQ ID No: 3)) via a viral vector. NCI-H82 cells with low NMT protein expression (sh-DNMT1 NCI-H82 cells) were obtained by introducing the gene into an empty viral vector that does not contain the NNMT gene or shRNA (Con-NCI-H82 cells). The results regarding the DNMT1 protein content in Con-NCI-H82 cells and ov-NNMT NCI-H82 cells detected by Western Blot experiments, and the DNMT1 protein content in Con-NCI-H82 cells and sh-DNMT1 NCI-H82 cells detected by Western Blot experiments, are shown in Figures 3 and 4. As can be seen from Figures 3 and 4, NNMT protein is highly expressed in ov-NNMT NCI-H82 cells and knocked down, i.e., low-expressed, DNMT1 protein in sh-DNMT1 NCI-H82 cells compared to Con-NCI-H82 cells.

[0678] The cell vitality of Con-NCI-H82 cells, ov-NNMT NCI-H82 cells, and sh-DNMT1 NCI-H82 cells was detected using the Promega CellTiter-Glo kit (which reflects cell vitality by examining the intracellular ATP content). The results are shown in Figures 5 and 6. As can be seen from Figures 5 and 6, the cell vitality of on-NCI-H82 cells, ov-NNMT NCI-H82 cells, and sh-DNMT1 NCI-H82 cells is almost the same. There is no statistical significance in the differences in cell vitality.

[0679] By using the Promega CellTiter-Glo kit, that is, by examining the ATP content within cells via the kit, cell vitality was detected, and the inhibitory effects of the various compounds prepared in this example on Con-NCI-H82 cells, ov-NNMT NCI-H82 cells, and sh-DNMT1 NCI-H82 cells (IC) were determined. 50 The system detects the following, and the results are shown in Table 7. [Table 7] JPEG0007843542000053.jpg42161Note:IC 50 The '-' represents the 50% inhibiting concentration, i.e., the concentration of the inhibitor at which a 50% inhibitory effect is achieved. Con-NCI-H82 represents the control group of NCI-H82 cells into which the NNMT gene and shRNA are introduced into an empty viral vector. ov-NNMT NCI-H82 represents the experimental group of NCI-H82 cells into which the NNMT gene is introduced into a viral vector containing the NNMT gene, resulting in high expression of the NNMT protein in ov-NNMT NCI-H82 cells. sh-DNMT1 NCI-H82 represents the experimental group of NCI-H82 cells into which the shRNA is introduced into a viral vector containing the NNMT protein, resulting in knockdown (i.e., low expression) of the NNMT protein in ov-NNMT NCI-H82 cells.

[0680] As can be seen from Table 7, in this embodiment, by overexpressing the NNMT protein in NCI-H82 cells and knocking down the expression of DNMT1 in NCI-H82 cells, the compound of the present invention has a remarkable inhibitory effect on tumor cells that have low or no NNMT gene expression and high DNMT1 expression, but has an inferior inhibitory effect on tumor cells that have high NNMT gene expression and low DNMT1 expression. Furthermore, the inhibitory effect of the compound of the present invention is enhanced by lowering the expression of the NNMT gene in tumors or increasing the expression of DNMT1 in tumors, and the amount of NNMT expression in tumor cells is significantly inversely correlated with the sensitivity to the compound of the present invention, while the amount of DNMT1 expression in tumor cells is significantly positively correlated with the sensitivity to the compound of the present invention.Therefore, the compound of the present invention has a remarkable inhibitory effect on tumor cells that have low or no NNMT gene expression and high DNMT1 expression, and tumor cells that have low or no NNMT gene expression and high DNMT1 expression are highly sensitive to the compound of the present invention, thus providing a remarkably superior therapeutic effect on tumor cells that have low or no NNMT gene expression and high DNMT1 expression.

[0681] Example 17 The methylation level of cellular DNA is maintained by DNA methyltransferases DNMT3a, DNMT3b, and DNMT1. DNMT3a and DNMT3b perform de novomethylation of DNA, while DNMT1 replicates and maintains methylated DNA with the help of the protein UHRF1 (a ubiquitin-like tau protein 1 containing PHD and ring finger domains). This example detects the correlation between NNMT expression in tumors and the expression of DNMT1, UHRF1, DNMT3a, and DNMT3b.

[0682] Experimental Methods and Results: Expression data for NNMT genes, DNMT1, UHRF1, DNMT3a, and DNMT3b were obtained from a publicly available database (Cancer Cell Line Encyclopedia, CCLE, total of 1019 cell lines) in various cells. Next, the correlation between NNMT expression and DNMT1, UHRF1, DNMT3a, and DNMT3b expression in these cells, as well as the correlation between the expression levels of NNMT genes in each cell and the expression levels of DNMT1, UHRF1, DNMT3a, and DNMT3b, were analyzed using bioinformatics methods. The experimental results are shown in Figure 7.

[0683] As can be seen from Figure 7, the expression of NNMT in each cell is inversely correlated with the expression of DNA methyltransferase and UHRF1. Therefore, tumor cells that highly express DNA methyltransferase and UHRF1 are highly sensitive to the compounds of the present invention, and the compounds of the present invention have remarkably excellent therapeutic effects against tumors that highly express DNA methyltransferase and UHRF1.

[0684] It should be noted that the above description, as an embodiment designed to address a certain aspect, has been improved by those skilled in the art without departing from the principles of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
