Abstract
Description
Cancer treatment composition comprising cannabigerol and / or cannabidiol and rivoceranib and the use thereof
[0001] The present invention relates to a pharmaceutical composition for the prevention or treatment of cancer comprising cannabizerol and rivoceranib as active ingredients, and to the use thereof.
[0002] Cannabis sativa L. is an annual plant of the genus Cannabis of the family Cannabaceae that has been widely cultivated in tropical and temperate regions, centered in Central Asia, for 12,000 years. It includes wild hemp and refers collectively to Cannabis chemovars and their variants, including varieties var. indica and var. kafiristanica, as well as Cannabis sativa subspecies sativa, Cannabis sativa subspecies indica, Cannabis sativa subspecies ruderalis, and their genetically crossbred, self-crossbred, or hybrid plants containing various types of cannabinoid compounds known as medicinal and pharmaceutical components.
[0003] In traditional medical texts from China and Korea, hemp seeds with the hulls removed, known as *Majain* or *Hwamain*, have been used for constipation, diabetes, pain disorders, menstrual irregularities, skin diseases, and dysentery. Additionally, hemp leaves (*Macha*, *Mayeop*) have been used as an anthelmintic, hair protectant, for asthma, for pain relief, anesthesia, and as a diuretic. Furthermore, records indicate that hemp roots were used for treating difficult childbirth and resolving blood stasis, hemp bark for bruises and open wounds, hemp flowers for paralysis and itching, and hemp powder was used for difficult childbirth, constipation, gout, phlegm, and insomnia, with each part of the hemp plant being used according to the specific condition.
[0004] Meanwhile, according to an analysis by Statistics Korea, cancer is the leading cause of death in South Korea, accounting for 31.7% of deaths among men and 22.5% among women, with 31.7% of the total population dying from cancer. Treatment methods include surgery, radiation therapy, and chemotherapy; however, these methods are often accompanied by side effects or are applied restrictively depending on the stage of cancer progression. In particular, most anticancer drugs operate by halting the cell cycle of rapidly dividing cells and causing their death. Consequently, they attack normally dividing cells in addition to active ones, leading to side effects such as hair loss, loss of appetite, and weakened immunity due to a decrease in white blood cells. Therefore, there is a need for technology that can maximize therapeutic efficacy while using low concentrations of anticancer drugs.
[0005] Against this background, the present invention was completed by confirming significantly enhanced anticancer efficacy resulting from the combined treatment of cannabizerol and rivoceranib.

[0104] The following examples will be explained in more detail. However, these examples are for illustrative purposes only and the scope of the present invention is not limited to these examples.
[0105]
[0106] Example 1: Evaluation of anticancer efficacy under in vitro conditions following combination treatment of cannabigerol (CBG) and rivoceranib
[0107] To evaluate the anticancer activity of combination therapy with cannabigerol (CBG) and rivoceranib, the following experiment was performed.
[0108] First, as an example of cancer cells, HepG2 cells, a liver cancer cell line, were placed in a 96-well plate at a ratio of 1 x 10 4Cells were inoculated at a cells / well concentration and cultured for 24 hours in a 37°C, 10% CO2 incubator. Subsequently, riboceranib was added at various concentrations and cultured for an additional 48 hours under the same conditions. After the culture was completed, WST-8 solution (Quanti-Max™, BIOMAX, Korea) was added to the medium at a 1 / 10 volume ratio and incubated at 37°C for 1 hour. Cell viability was calculated by measuring absorbance at 450 nm. Cell viability was expressed as a ratio relative to the untreated control group, and this experiment was performed independently in triplicate. As a result of the above experiment, the IC50 for riboceranib in HepG2 cells 50 The value was confirmed to be 28.1 μM (Fig. 1), and it can be seen that at concentrations below this level, it does not exhibit significant cytotoxicity to HepG2 cells.
[0109] Next, to screen for compounds among various cannabis-derived compounds that exhibit excellent synergistic effects with riboceranib, the treatment concentration of riboceranib was set to 20 μM, a concentration that does not exhibit cytotoxicity to cancer cells on its own, and anticancer activity against HepG2 cells, a liver cancer cell line, was confirmed by co-treatment with various cannabis-derived compounds. As a result of the above experiment, it was confirmed that among the cannabis-derived compounds, cannabigerol (CBG) significantly increased cytotoxicity to HepG2 cells in the co-treatment group compared to the riboceranib monotherapy group compared to other cannabis-derived compounds (Fig. 2).
[0110] Next, as a result of confirming the anticancer activity following combination treatment with cannabigerol and riboceranib in various liver cancer cell lines, the IC50 of riboceranib upon combination treatment with cannabigerol in various liver cancer cell lines 50 As it was confirmed that the value decreased by more than 50% (Fig. 3), it can be seen that the anticancer activity of riboceranib was significantly increased by cannabigerol.
[0111] In addition, to evaluate the synergistic effect of the combination treatment of cannabigerol and riboceranib, the ZIP Synergy score was calculated, and a high value of 11.48 was confirmed (Fig. 4).
[0112]
[0113] Example 2: Evaluation of anti-inflammatory efficacy under in vivo conditions following combination treatment of cannabigerol (CBG) and rivoceranib
[0114] To evaluate the in vivo anticancer activity of cannabigerol (CBG) and rivoceranib combination therapy, the following experiment was performed.
[0115] Specifically, as an example of cancer cells, to construct a xenograft mouse model using the HepG2 cell line, HepG2 cells were suspended in RPMI in BALB / c nude mice (male, 4 weeks old) at a rate of 1 x 10 7 Tumors were induced by subcutaneous injection at a concentration of cells / mouse. From the time the tumor size reached approximately 50 to 100 mm³, mice were randomly divided into groups of 5: (1) control group, (2) sorafenib monotherapy group (50 mg / kg), (3) rivoceranib monotherapy group (50 mg / kg), (4) cannabizerol monotherapy group (50 mg / kg), and (5) cannabizerol (100 mg / kg) and high-concentration rivoceranib combination therapy group (50 mg / kg). Each drug was administered orally at a scheduled dose and frequency, and the antitumor effect was evaluated by periodically measuring changes in tumor size and body weight over a certain period.
[0116] As a result of the above experiment, it was confirmed that the tumor growth inhibitory effect was significantly improved in the group treated with cannabigerol (CBG) and riboceranib in combination compared to the group treated with riboceranib alone (Fig. 5).
[0117] Based on the above results, it can be seen that the combined treatment of CBG and Rivoceranib exhibits a significantly superior synergistic effect of enhanced anticancer activity against cancer.
[0118]
[0119] Example 3: Analysis of the anticancer mechanism of action of combination therapy with cannabigerol (CBG) and rivoceranib
[0120] To analyze the mechanism of action of anticancer activity following the combination treatment of cannabigerol (CBG) and rivoceranib, the following experiments were performed.
[0121] Specifically, as an example of cancer cells, HepG2 liver cancer cell lines were placed in a 6-well plate at a rate of 3×10 5 After inoculating at a cell / well concentration and culturing for 48 hours in a 37°C, 10% CO2 incubator, the cells were treated with (1) a control group, (2) a group treated with riboceranib alone (10 μM), (3) a group treated with cannabigerol alone (20 μM), and (4) a group treated with cannabigerol (20 μM) and riboceranib in combination (10 μM), and then further cultured for 48 hours under the same conditions.
[0122] Next, to confirm the expression levels of apoptosis and cell cycle-related factors in the cultured cells, Western blotting was performed to determine the expression levels of CHOP (C / EBP-homologous protein), Cleaved PARP (Poly (ADP-ribose) polymerase), Cleaved caspase9, Cleaved caspase8, Cleaved caspase3, and FOXM1 (Forkhead box protein M1) proteins.
[0123] As a result of the above experiment, it was confirmed that in the group treated with the combination of cannabigerol and riboceranib, the levels of cell death-related factors Cleaved PARP, Cleaved caspase9, Cleaved caspase8, Cleaved caspase3, and CHOP proteins increased (Fig. 6), and the expression level of FOXM1, a cell cycle and cell proliferation-related factor, decreased (Fig. 7).
[0124] Based on the above results, it can be seen that the combination treatment of cannabigerol and rivoceranib can exhibit an anticancer effect by promoting apoptosis in cancer cells through the induction or inhibition of the expression of apoptosis and cell cycle-related factors.
[0125]
[0126] Example 4: Evaluation of anticancer efficacy against various cancer types following combination treatment of cannabigerol (CBG) and rivoceranib
[0127] To evaluate the anticancer activity of cannabigerol (CBG) and rivoceranib combination therapy in various cancer types, the following experiments were performed.
[0128]
[0129] 4.1: Evaluation of Anticancer Activity Against Colorectal Cancer
[0130] To evaluate anticancer activity against colorectal cancer, a xenograft mouse model using the colorectal cancer cell line RKO was constructed and evaluated.
[0131] Specifically, RKO cells were suspended in RPMI in BALB / c nude mice (male, 4 weeks old) at a rate of 1 x 10 7Tumors were induced by subcutaneous injection at a concentration of cells / mouse. When the tumor size reached approximately 50 to 100 mm³, mice were randomly divided into groups of 5: (1) control group, (2) 5-Fluorouracil monotherapy group (40 mg / kg), (3) cannabigerol monotherapy group (100 mg / kg), (4) riboceranib monotherapy group (100 mg / kg), and (5) cannabigerol (100 mg / kg) and riboceranib combination therapy group (100 mg / kg). 5-Fluorouracil was administered intraperitoneally (once a week), and the remaining drugs were administered orally daily. Subsequently, changes in tumor size and body weight were periodically measured over a certain period to evaluate the antitumor effect.
[0132] As a result of the above experiment, there was no difference in body weight among the experimental groups (Fig. 8), and it was confirmed that the tumor growth inhibitory effect was significantly improved in the combination treatment group compared to the rivoceranib monotherapy group (Fig. 9).
[0133] Next, analysis of the protein expression levels of apoptosis-related factors revealed that in the group treated with cannabigerol and riboceranib, the levels of Cleaved PARP, Cleaved caspase9, Cleaved caspase8, and Cleaved caspase3 proteins increased, while the expression of Bcl-2, an apoptosis inhibitor, decreased (Fig. 10).
[0134] Based on the above results, it can be seen that the combined treatment of cannabigerol and rivoceranib demonstrates a significantly superior synergistic effect of anticancer activity against colorectal cancer.
[0135]
[0136] 4.2: Evaluation of anticancer activity against additional cancer types
[0137] To evaluate the anticancer activity of combination therapy with cannabigerol (CBG) and rivoceranib against lung cancer, gastric cancer, prostate cancer, breast cancer, and biliary tract cancer, the following experiments were performed.
[0138] Specifically, 1 x 10 cancer cells per 96-well plate 4 Cells were inoculated at a cell / well concentration and cultured for 24 hours in a 37°C, 10% CO2 incubator. Subsequently, the cells were treated with riboceranib at various concentrations, or treated with cannabigerol at non-cytotoxic concentrations (10 μM and 5 μM) or left untreated, and cultured for an additional 48 hours under the same conditions. After the culture was completed, WST-8 solution was added to the medium at a 1 / 10 volume ratio and incubated at 37°C for 1 hour; cell viability was calculated by measuring absorbance at 450 nm. Cell viability was expressed as a ratio relative to the untreated control group, and this experiment was performed independently in triplicate.
[0139] As a result of the above experiment, it was confirmed that the survival rate of cancer cells in lung cancer, gastric cancer, prostate cancer, breast cancer, and bile duct cancer cell lines was significantly reduced in the group treated with the combination of cannabigerol and riboceranib compared to the group treated with riboceranib alone (Fig. 11).
[0140] Based on the above results, it can be seen that the combination treatment of cannabigerol and rivoceranib exhibits significantly superior anticancer activity compared to monotherapy in various cancer types, including lung cancer, gastric cancer, prostate cancer, breast cancer, and biliary tract cancer.
[0141]
[0142] Example 5: Evaluation of anticancer efficacy against various cancer types following triple combination treatment of cannabigerol (CBG), cannabidiol (CBD), and rivoceranib
[0143] The anticancer activity of triple combination therapy with cannabizerol (CBG), cannabidiol (CBD), and rivoceranib was evaluated as follows.
[0144] Specifically, as an example of various cancer types, liver cancer, colorectal cancer, and pancreatic cancer cells were placed in a 96-well plate at a ratio of 1 x 10 4 Cells were inoculated at a cell / well concentration and cultured for 24 hours in a 37°C, 10% CO2 incubator. Subsequently, riboceranib was treated at various concentrations, and additionally cultured for 24 hours under the same conditions with cannabigerol and / or cannabidiol at non-cytotoxic concentrations (20 μM) or without treatment. After the culture was completed, WST-8 solution was added to the medium at a 1 / 10 volume ratio and incubated at 37°C for 1 hour; cell viability was calculated by measuring absorbance at 450 nm. Cell viability was expressed as a ratio relative to the untreated control group, and this experiment was performed independently three times.
[0145] As a result of the above experiment, it was confirmed that the toxicity to liver, colorectal, and pancreatic cancer cells was significantly increased when cannabigenol, cannabidiol, and riboceranib were triple-combined compared to treatment with riboceranib alone or treatment with riboceranib and cannabigenol (Figs. 12 to 14).
[0146] Based on the above results, it can be seen that the triple combination treatment of cannabigerol, cannabidiol, and riboceranib exhibits significantly superior cancer cell toxicity compared to the combination treatment of cannabigerol and riboceranib.
[0147]
[0148] Example 6: Further analysis of anticancer efficacy following triple combination treatment of cannabigerol (CBG), cannabidiol (CBD), and rivoceranib
[0149] To further analyze the anticancer activity resulting from triple combination therapy with cannabigenol (CBG), cannabidiol (CBD), and rivoceranib, the following experiment was performed.
[0150] Specifically, as an example of a carcinoma, the colorectal cancer cell line CT-26 is placed in a 96-well plate at a ratio of 1 x 10 4Cells were inoculated at a cell / well concentration and cultured for 24 hours in a 37°C, 10% CO2 incubator. Subsequently, riboceranib was treated at various concentrations, and additionally cultured for 48 hours under the same conditions with cannabigerol and cannabidiol at non-cytotoxic concentrations (10 μM) or without treatment. After the culture was completed, WST-8 solution was added to the medium at a 1 / 10 volume ratio and reacted at 37°C for 1 hour; cell viability was calculated by measuring absorbance at 450 nm. Cell viability was expressed as a ratio relative to the untreated control group, and this experiment was performed independently in triplicate.
[0151] As a result of the above experiment, it was confirmed that the toxicity to mouse colon cancer cells was significantly increased when cannabigenol, cannabidiol, and riboceranib were triple-combined compared to treatment with riboceranib alone or treatment with riboceranib and cannabigenol (Figs. 15 and 16).
[0152] Next, analysis of the protein expression levels of apoptosis-related factors revealed that the expression levels of Cleaved PARP and Cleaved caspase8 proteins increased in the triple combination treatment group of cannabigerol, cannabidiol, and rivoceranib (Fig. 17).
[0153] Next, to construct an allograft mouse model using the CT-26 cell line, CT-26 cells were suspended in RPMI and 1 x 10⁻¹⁰ cells were fed to BALB / c mice (male, 4 weeks old). 7Tumors were induced by subcutaneous injection at a concentration of cells / mouse. When the tumor size reached approximately 50 to 100 mm³, mice were randomly divided into groups of three: (1) a control group, and (2) a triple combination treatment group consisting of cannabizerol (50 mg / kg), cannabidiol (50 mg / kg), and rivoceranib (50 mg / kg). Each drug was administered orally at a scheduled dose and frequency. Subsequently, changes in tumor size and body weight were periodically measured over a certain period to evaluate the anti-tumor effect, and it was confirmed that the tumor growth inhibition effect was significantly enhanced in the triple combination treatment group compared to the control group (Fig. 18).
[0154]
[0155] Example 9: Evaluation of Immune Checkpoint Inhibitory Effects of Triple Combination Treatment with Cannabigerol (CBG), Cannabidiol (CBD), and Rivoceranib
[0156] To confirm the immune checkpoint inhibitory effect of triple combination therapy with cannabigerol (CBG), cannabidiol (CBD), and rivoceranib, the following experiment was performed.
[0157] Specifically, as an example of a carcinoma, the colorectal cancer cell line RKO or the liver cancer cell line HepG2 is placed in a 6-well plate at a ratio of 3 x 10 5 Cells were inoculated at a concentration of cells / well and cultured for 24 hours in an incubator at 37°C under 10% CO2 conditions. Subsequently, riboceranib (5 μM) and cannabigerol and cannabidiol (at non-cytotoxic concentrations of 20 μM) were treated individually or in combination and cultured under the same conditions for 24 hours. After the completion of culture, total RNA was extracted from each cell and cDNA was synthesized via reverse transcription. The expression level of the PD-L1 (CD247) gene was analyzed using quantitative real-time qRT-PCR. Relative expression levels were calculated using GAPDH as an endogenous control.
[0158] As a result of the above experiment, it was confirmed that in the colorectal cancer cell line RKO and liver cancer cell line HepG2, the expression of the PD-L1 gene was significantly reduced in the triple combination treatment group of cannabigerol, cannabidiol, and riboceranib compared to other experimental groups (Fig. 19).
[0159] Based on the above results, it can be seen that the combined treatment of cannabigerol and cannabidiol can inhibit the expression of PD-L1, an immune checkpoint factor in cancer cells, and that triple combination treatment with the addition of rivoceranib further inhibits PD-L1 expression, suggesting the possibility of involvement in the regulation of anticancer responses mediated by immunological mechanisms.
