After stirring at room temperature for 12 h, the reaction was stopped. The solid product in the reaction flask was extracted with water and ethyl acetate. The organic phases were combined, concentrated, and then separated by column chromatography (developing solvent: petroleum ether: ethyl acetate = 3:1) to obtain the product purpurogenol (3), a yellow solid compound. The yields of sodium hydroxide, potassium hydroxide, and lithium hydroxide as bases were 78%, 62%, and 60%, respectively. Therefore, sodium hydroxide was selected as the base in other embodiments.
[0076] S2. Toluene (5 mL, CAS: 108-88-3), ethanol (5 mL, CAS: 64-17-5), dimethylformamide (5 mL, CAS: 68-12-2), acetonitrile (5 mL, CAS: 75-05-8), 1,4-dioxane (5 mL, CAS: 123-91-1) or tetrahydrofuran (5 mL, CAS: 109-99-9) were added to purpurone (178 mg, 1 mmol), and the mixture was heated to reflux and stirred to dissolve. Subsequently, morpholine (113 mg, 1.3 mmol, CAS: 110-91-8) and benzaldehyde (127 mg, 1 .2mmol, CAS: 110-52-7) was stirred, and after 0.5 h, an aqueous solution of sodium bicarbonate (10 mL, CAS: 144-55-8) was added to quench the reaction, followed by extraction with ethyl acetate. The organic phases were combined, concentrated, and then separated by column chromatography (developing solvent: dichloromethane:methanol = 50:1) to obtain the product, porphyrone Mannich base compound A1, as a yellow solid compound. The yields using toluene / ethanol / dimethylformamide / acetonitrile / 1,4-dioxane / tetrahydrofuran as solvent were 42%, 35%, 38%, 15%, 12%, 8% and 1%, respectively. Therefore, toluene was selected as the solvent in other examples.

[0362] Application Example 1
[0363] In this application example, cytotoxicity tests were conducted on seven tumor cell lines using the porphyrin ketone Mannich base compounds obtained in Examples 1 to 32 and the substrate porphyrin ketone.
[0364] First, seven tumor cell lines (mouse triple-negative breast cancer cells 4T1, human colon cancer cells HCT116, mouse colon cancer cells MC38, human ovarian cancer cells A2780, human non-small cell lung cancer cells A549, human triple-negative breast cancer cells MDA-MB-231 and human breast cancer cells T47D) were revived. Afterwards, when the cells were in the logarithmic growth phase, the growth inhibitory activity of the compound on tumor cells was determined using MTT (methylthiazolium tetrazolium method). The culture medium in the culture dish was aspirated, the cells were rinsed twice with 3 mL PBS, 1 mL of trypsin was added to digest the cells, and then 3 mL of DMEM complete medium was added to terminate the digestion. The cells were centrifuged at 1000 rpm for 5 minutes and then the cells were counted and the cell concentration was adjusted to 2*10 4 / mL, then seeded in a 96-well plate at 100μL / well and placed in an incubator. After 12 hours, when the cells are completely attached, the culture medium is discarded and the drug-containing culture medium is added. Set up a drug-dosing group (the Mannich base derivatives of porphyrin ketone and porphyrin ketone are prepared into a 50mM stock solution with DMSO, diluted 1000 times in the culture medium to make the final concentration of 50μM, and then diluted half and half to 25, 12.5, 6.25, 3.125, 1.5625μM), a blank group (culture medium containing 1‰ DMSO), a positive control group (cisplatin, prepared in the same way as the drug-dosing group) and a zero-adjustment group (culture medium without cells), with 3 replicates per group. After 72 hours of drug treatment, 10 μL of MTT solution (5 mg / mL) was added to each well and the cells were placed in an incubator for 4 hours. The culture medium was discarded and 100 μL of DMSO was added to each well. The cells were shaken on a shaker for 10 minutes to fully dissolve the crystals. The OD value was measured at 490 nm using a microplate reader. The cell viability was calculated according to the following formula: Viability (%) = (OD 药物组 -OD 调零组 ) / (OD 空白组 -OD 调零组 ) × 100%. After calculating the cell viability at different concentrations of each compound, GraphPad Prism 8.00 was used to fit the cell growth curve and calculate the half-maximal inhibitory concentration (IC) of the drug.50 The experiment was repeated 3 times. The experimental results are shown in Table 1.
[0365] The results in Table 1 show that the chloranthone Mannich base compounds have a broad spectrum of toxicity against tumor cells, with strong inhibitory effects on all seven tumor cell types. Compared with the substrate chloranthone, the modified derivatives showed a stronger effect in inhibiting tumor cell proliferation. Among them, compound B14 became the most promising compound in the series, with superior tumor cell toxicity to the parent compound chloranthone against all seven tumor cell lines, especially against five tumor cell lines: 4T1, MDA-MB-231, HCT116, MC38, and A2780. 50 The value is less than or equal to 10 μM, which is significantly better than the parent compound purpurogenol. As a preferred example, one of the compounds B14 is used as an example for explanation, and the embodiments of the remaining compounds can be designed by analogy.
[0366] In Table 1, >50 means that the survival rate of tumor cells is still greater than 50% when the drug concentration is 50 μM, that is, the cytotoxicity is very weak.
[0367] Table 1: Inhibitory effects of porphyrin ketone Mannich base derivatives obtained in Examples 1-32 and porphyrin ketone on seven tumor cell lines
[0368]
[0369] Application Example 2 In this application example, the anti-breast cancer cell colony-forming ability of the porphyrin ketone Mannich base compound B14 obtained in Example 28 was tested in vitro.
[0370] The experimental procedure is as follows: First, prepare a cell suspension of well-growing cells. Then, evenly plate 4T1 cells at a density of 500 / well, MDA-MB-231 cells at 2000 / well, and T47D cells at 3000 / well onto a six-well cell culture plate. After the cells have fully adhered, each well is stimulated with drugs at concentrations of 10, 5, 2.5, and 0 μM for 72 hours. The cells are then replaced with normal culture medium and cultured for 5-15 days, with the medium being changed every three days until microscopic cell colonies are formed. Cultivation is then stopped. The culture medium is discarded, the cells are washed once with PBS, and 1 mL of tissue fixative is added to each well. Fix for 50 minutes, wash once more with PBS, and then add 1 mL of 0.1% crystal violet stain. Stain for 20 minutes, then rinse twice with PBS. After the PBS in the wells has dried, the wells are photographed.
[0371] The number of cell clones formed after treatment with different concentrations of drugs is as follows Figure 1As shown, the number of colonies in the three breast cancer cell lines decreased in a dose-dependent manner with increasing drug concentration. A concentration of 2.5 μM blocked over 50% of colony formation, and at a concentration of 10 μM, virtually no colonies formed in the culture plate. The effect was particularly pronounced on 4T1 cells. Therefore, compound B14 can dose-dependently inhibit the formation of colonies in the three breast cancer cell lines, demonstrating its anti-proliferative activity.
[0372] Application Example 3
[0373] In this application example, the anti-breast cancer cell migration ability of the porphyrin ketone Mannich base compound B14 obtained in Example 28 was tested in vitro.
[0374] MDA-MB-231 cells were prepared as a cell suspension and seeded at 800,000 cells / dish in 35 mm culture dishes. After complete attachment of the cells, a scratch was made on the dish using a pipette tip. The culture medium was then prepared with serum-free medium containing the drug at concentrations of 10, 5, 2.5, and 0 μM. Microscopic photographs were taken after 0, 12, 24, and 36 hours to observe the healing of the scratch. The healing area was calculated using Image J, and the differences between the groups were statistically analyzed using GraphPad Prism 8.00.
[0375] like Figure 2 As shown, the cells in the Control group healed faster with time, while the cells in the drug group healed slower and in a dose-dependent manner. Comparing the healing areas of the cells in each group after 36 hours, it can be seen that the healing area of the cells in the Control group reached more than 75%, while the healing area was 43% when the drug concentration was 5 μM, and the healing area was 22% when the drug concentration was 10 μM, which was significantly different from the Control group and was dose-dependent. Therefore, compound B14 can significantly reduce the migration ability of triple-negative breast cancer cells MDA-MB-231 ( Figure 2 **p<0.01, ***p<0.001) compared with the control group.
[0376] Application Example 4
[0377] This application example tests the ability of the porphyrin ketone Mannich base compound B14 obtained in Example 28 to promote apoptosis of breast cancer cells in vitro.
[0378] This experiment was conducted using the Annexin V-APC / PI apoptosis kit from Linktech Biopharm. Three breast cancer cells (4T1, MDA-MB-231, and T47D) were seeded at appropriate densities in 6-well cell culture plates. Twenty-four hours after administration, the cells were harvested and washed once with PBS. The supernatant was discarded, and the cells were resuspended in 500 μL of 1× Binding Buffer. Subsequently, 5 μL of Annexin V-APC and 10 μL of PI were added to each tube. After incubation in the dark for 5 minutes, the cells were analyzed using a flow cytometer. GraphPad Prism 8.00 was used to analyze the differences between the groups.
[0379] like Figure 3 As shown, the number of apoptotic cells in the three breast cancer cells increased significantly after drug treatment, and was dose-dependent. In cells 4T1 and MDA-MB-231, the number of apoptotic cells at the three doses was significantly different from that in the Control group, and there were significant differences between the high-dose group and the low-dose group, and between the high-dose group and the medium-dose group. The apoptosis rate of the high-dose group exceeded 50%. In T47D cells, the number of apoptotic cells in the medium-dose group and the high-dose group was significantly increased compared with the Control group, and there were significant differences between the low-dose group and the medium-dose group, the low-dose group and the high-dose group, and the medium-dose group and the high-dose group. Therefore, compound B14 can induce breast cancer cells, especially triple-negative breast cancer cells, to apoptosis, further inhibiting the proliferation of tumor cells ( Figure 3 *p<0.05, **p<0.01, ****p<0.0001 compared with the control group, and the medium-dose group and low-dose group & p<0.05, comparison between high-dose group and low-dose group # p<0.05, #### p<0.0001, comparison between high-dose group and medium-dose group $ p<0.05, $$ p<0.01, $$$ p<0.001).
[0380] Application Example 5
[0381] This application example tests the in vivo anti-tumor activity of the porphyrin ketone Mannich base compound B14 obtained in Example 28.
[0382] The experimental method used was to select healthy female Balb / C mice and adaptively feed them for one week while culturing 4T1 cells. After digestion and centrifugation of the 4T1 cells in the logarithmic growth phase, the cell concentration was adjusted to 1*10 7The tumor size was 90 mm / mL and the tumor volume was 100 μL per mouse. 3 Mice were randomly divided into five groups based on tumor volume. Cisplatin and tamoxifen served as positive controls: a high-dose B14 group (40 mg / kg), a low-dose B14 group (10 mg / kg), a cisplatin group (2 mg / kg), a tamoxifen group (10 mg / kg), and a control group, with nine mice in each group. Immediately after grouping, drugs were administered via intraperitoneal injection (5% DMSO + 5% Tween + 90% saline; the control group received the same volume of solvent). This marked the first day of treatment. Dosing was performed once daily, and tumor length and width, as well as mouse body weight, were measured. After 14 consecutive days of dosing, tumor length and width, as well as mouse body weight, were measured the following day. Mice were then sacrificed by cervical dislocation, and tumors and organs were removed and weighed. Tumors in each group were arranged in order of size and photographed. Tumors from three mice per group were fixed with tissue fixative for H&E staining and analysis. All organs were then stored at -80°C until further use. GraphPad Prism 8.00 was used to statistically analyze the differences between the corresponding groups and the in vivo anti-tumor effect of the target compound B14.
[0383] The formula for calculating mouse tumor volume is: volume (V / mm 3 ) = length * width * width / 2
[0384] Tumor Growth Inhibtion (TGI) formula: TGI (%) = (W c -W t ) / W c ×100%(W c is the average weight of tumors in the control group of mice, W t is the average weight of tumors in the mice in the drug-treated group)
[0385] The statistical trend of the change of mouse tumor volume during the 14-day drug administration is as follows Figure 4 , 5, 6 (Day 15 is the data of the day of sampling, no drug was given). Compared with the Control group, both the high-dose group and the low-dose group showed significant anti-tumor effects. From the second day on, the tumor volume was significantly different from that of the Control group, and there was a significant difference between the high-dose group and the low-dose group ( Figure 4 *p<0.05, ***p<0.001, ****p<0.0001 compared with the control group; *p<0.05, ***p<0.001, ****p<0.0001 compared with the control group; ## p<0.01, #### p<0.0001; comparison between high-dose group and low-dose group $ p<0.05,$$ p<0.01), there was a significant difference between the low-dose group and the tamoxifen group on day 15 ( Figure 5 Tamoxifen group compared with control group *p<0.05, ***p<0.001, ****p<0.0001; low-dose group compared with tamoxifen group $ p<0.05), there was no significant difference between the high-dose group and the cisplatin group ( Figure 6 *p<0.05, ****p<0.0001) compared with the control group.
[0386] After the last administration, the tumor and organs were weighed after sampling the next day. Figure 7 As shown, compared with the Control group, both the high-dose group and the low-dose group showed significant anti-tumor effects, among which the TGI of the high-dose group was 46%, which was equivalent to the positive control cisplatin (43%), and the TGI of the low-dose group was 33%, which was equivalent to the positive control tamoxifen (27%). In addition, there was a significant difference in TGI between the high-dose group and the low-dose group, indicating that compound B14 has a dose-dependent anti-tumor effect ( Figure 7 ***p<0.001, ****p<0.0001 compared with the control group, high-dose group compared with the low-dose group ## p<0.01). The tumor morphology of each group was as follows Figure 8 As shown. H&E staining of tumor tissue ( Figure 9 , n=3), it can be seen that the tumor tissue of the Control group showed active proliferation of breast cancer cells; the tumor tissue of the low-dose B14 group had blurred boundaries, missing cell nuclei, and necrosis; while the high-dose B14 group underwent large-area necrosis of cells, further confirming the anti-tumor effect.
[0387] The weight changes of mice in each group during the administration process were analyzed. Figure 10 As shown, the high-dose and low-dose B14 groups and the tamoxifen group showed the same trend as the control group. The weight of mice in the cisplatin group gradually decreased, and there was a significant difference compared with the control group from the 6th day. On the 15th day, the average weight of mice in the cisplatin group decreased by 16.7%, indicating that cisplatin is more toxic to Balb / C mice and has poor in vivo safety. Compound B14 had no significant effect on the weight of mice, which preliminarily illustrates the in vivo safety of purpurogenol Mannich base compounds ( Figure 10 **p<0.01, ****p<0.0001) compared with the control group.
[0388] Application Example 6
[0389] This application example further conducted an in vivo safety evaluation on the porphyrin ketone Mannich base compounds B8 and B14 obtained in Examples 22 and 28.
[0390] Healthy female Balb / C mice were acclimated for one week and randomly divided into three groups of eight: the B8 (60 mg / kg) group, the B14 (60 mg / kg) group, and the control group. The mice were then administered intraperitoneally for 14 consecutive days. On the 15th day, the mice were weighed, blood was collected from the eyeballs, and organs including the heart, liver, spleen, lungs, and kidneys were harvested and weighed. Whole blood was divided into two halves: one half was heparinized and centrifuged (3000 rpm, 4°C, 15 minutes) to obtain the plasma sample, while the other half was directly centrifuged (3000 rpm, 4°C, 15 minutes) to obtain the serum sample. The samples were aliquoted and stored at -80°C. Serum was used to measure alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (CRE), and lactate dehydrogenase (LDH), and plasma was used to measure blood urea nitrogen (BUN) according to the kit instructions. Organs of three mice in each group were fixed in tissue fixative for H&E staining analysis. ALT, AST, CRE, and LDH were determined using the same kits from Nanjing Jiancheng.
[0391] The changes in body weight from administration on day 1 to sampling on day 15 were as follows: Figure 11 As shown in the table, the body weights of mice in the B8 (60 mg / kg) group, the B14 (60 mg / kg) group, and the Control group all showed an overall upward trend, indicating that compounds B8 and B14 had no significant effect on the body weight of mice. Figure 12 As shown, except for the significantly higher ALT in the serum of mice treated with compound B8 than in the control group, the other indicators showed no significant differences compared with the control group. The ALT, AST, CRE and LDH in the serum and BUN in the plasma of mice treated with compound B14 were normal compared with the control group, indicating that compound B8 has a slight toxicity to liver function, while compound B14 has no effect on the liver function, kidney function and normal cell growth of mice ( Figure 12 *p<0.05 in the comparison between group B8 and control). From the results of H&E staining of the organs of mice in each group ( Figure 13 ), no abnormalities were observed in the organs of the mice in the drug-treated group. Therefore, the porphyrin ketone Mannich base compounds provided by the present invention have good in vivo safety.
[0392] In summary, the present invention provides 32 porphyrin ketone Mannich base compounds, which have strong tumor cell toxicity against 7 tumor cell lines. Among them, the most active compound B14 can inhibit the cloning and migration of breast cancer cells in vitro and promote breast cancer cell apoptosis. It also shows a dose-dependent anti-tumor effect in the 4T1 in vivo tumor model of mice. In addition, the compound is safe in vivo at an effective dose and is expected to be further developed and studied, providing a new active organic small molecule for the research and development of new anti-breast cancer and other tumor drugs.
