Definitions
- the present invention relates to novel compounds, compositions and methods of preparation thereof, as well as uses thereof for treating cancer of various types, including: pancreatic, liver, breast, colon, brain and lung cancer.
- Cancer is a maj or public health problem worldwide and is the second leading cause of death in the United States.
- pancreatic adenocarcinoma is one of the most lethal due to its rapid growth and propensity to invade adjacent organs and metastasize.
- Ephedra is a genus of gymnosperm shrubs which belongs to the family of Ephedracea with over 30 registered species. As the majority of the gymnosperm plants, instead of fruits, it has bisexual strobilus which serves as food for birds. The leaves are degenerated and located in a sort of reddish membranous sheath on the stem which is green all year round. The various species of Ephedra are widespread throughout many lands. However, they are found in more abundance in southern Europe, Middle West, central Asia and northern China.
- Ephedra species especially E. sinica
- E. sinica have traditionally been used by the Chinese for a variety of medical purpose for at least 5000 years (Dewick, P.M.; 2009, Medicinal natural products, a biosynthetic approach, 3 rd edition, Wiley).
- Last studies have revealed to have anti-invasive, antiangiogenic and antitumor activities of Ephedra sinica extract (Nam, N.H. et al.; Phytother. Res. 2003 ,17, 70-76).
- Ephedra genus contains alkaloids as ephedrine (E) and pseudoephedrine (PE) which have been considered the primary pharmacologically active substances in Ephedra.
- E ephedrine
- PE pseudoephedrine
- Ephedra foeminea a particular species of the genus Ephedra, namely Ephedra foeminea, draw attention and interest as a potential agent for cancer treatment mainly due to two reasons: a) Surprisingly, no ephedrine alkaloids were identified in its chemical profile composition (Ibragic, S. et al.; Bosn. J. Basic. Med. Sci., 15), b) reports from patients diagnosed with different types of cancer that were apparently healed from their ailments by drinking an infusion prepared with Ephedra foeminea stalks, and a report on reducing various cancerous cells’ viability (Ben-Arye, E.; et al.; J. Cancer Res. Clin. Oncol. 2016, 142(7), 1499-1508; and Mendelovich, M. et al.; J. Med. Pla. Res. 2017, 11(43), 690-702, respectively).
- pancreatic adenocarcinoma Due to its rapid growth and prognostic to invade adjacent organs and metastasize pancreatic adenocarcinoma is considered one of the most lethal forms of cancer. The early stages of this cancer do not usually produce symptoms, so the disease is generally advanced when it is diagnosed (Lillemoe, K. D. et al.; Ca. Can. J. Clin. 2000, 50, 241-268). It is estimated that ninety-nine percent of patients with adenocarcinoma of the pancreas will die within 5 years of diagnosis (Jemal, A. et al.; Can. stat. 2003, 53, 5-26).
- Pancreatic cancer is the fourth leading cause of cancer-related death in the United States and is the seventh most common cause of death worldwide (Lillemoe, K. D. et al.; Ca. Can. J. Clin. 2000, 50, 241- 268). Treatment for pancreatic cancer is rarely effective because surgical excision offers the only possibility for a cure, and fewer than 15% of patients are candidates for tumor resection at the time of diagnosis. Chemotherapy provides only a slight survival advantage over surgical resection alone, and radiation therapy has not been demonstrated to be beneficial (Hazard, L.; Gast. Can. Res., 2009, 3, 20-28). More effective treatments are needed to improve the prognosis of patients with pancreatic cancer.

- in vitro results show that the compounds are able to significantly change the expression pattern of key proteins in cancer metabolism such as GLUT-4 receptor and E-cadherin.
- GLUT-4 is responsible for the glucose uptake which was showed to be impaired in treated cells generating a significant stress response.

- in vivo tests see e.g.
- Example 8 below performed on nude mice daily treated with compounds of this invention showed a significant increase of NK (natural killer) cells production which are very functional in the process of tumor regression.
- NK cells inhibit angiogenesis process. It is therefore contemplated, without being bound to any mechanism, that treated cells remain attached in situ lacking essential nutrients for normal growth and recede through necrosis. It is noteworthy that the involvement of NK cells and therefore the immune system to combat cancer is just one additional feature of this small molecule which behaves as a target therapy.
- the compounds of this invention could be classified as belonging to a class of chemotherapeutic compounds known as antimetabolites, which are defined as molecules able to interfere with mechanisms related to cell growth and replication and their efficacy as anticancer agents has been widely demonstrated (Shewach, D. S. et al.; Chem Rev. 2009, 109, 2859-2861; and Mihlon, F. et al.; Semin. Intervent. Radiol. 2010, 27, 384-390).
- Antimetabolite compounds can induce ligands for NK cell-activating receptors in mammalian tumor cells and promote NK cell-mediated tumor cytotoxicity (e.g.
- compound 10 may also be inducing the expression of NK receptors ligands, which can explain the significantly increased amount of NK cells in treated mice serum (e.g. Example 8, Figure 11). Nonetheless, the mechanisms involved in the induction of ligands for NK cell- activating receptors are only partially understood.
- Adherent Human carcinoma cell lines were cultured according to standard mammalian tissue culture protocols and sterile technique.
- Caco2, HepG2, MCF-7 cell lines were cultured in high glucose Dulbecco's Modified Eagle Medium
- HT29 cells were cultured in McCoy's 5 A medium
- Aspcl, A549, Mia Paca, U87MG and T98MG cells line were cultured in RPMI medium 1640 and HFF was culture in BIOAMF media. All media was supplemented with 10% fetal bovine semm, streptomycin (100 mg/ml), penicillin (100 U/ml) and Nystatin (12.5 U/ml).
- Cells were incubated in 5% C02 at 37 °C.
- tissue culture were maintained in 25cm ⁇ Nunc ⁇ cell culture treated EasYFlask ⁇ M (ThermoFisher scientific) and all the media and supplements were obtained from Biological Industries. Treatment were performed by plating cells in a Nunc ⁇ M 95 micro we ll delta surface plates (ThermoFisher scientific) in a starting confluence of 1 x 10 ⁇ cells/well. After 24h of incubation, the compound of interest was added in different concentrations as shown in the presented results.
- Viability of the cells following treatment was determined using a commercially available MTT assay kit (ABCAM, abl46345) and performed according to manufacturer's instmctions.
- the quantification was determined by measuring the optical density at 570 nm in an enzyme-linked immunosorbent assay (Spark, Tecan) reader. Data was presented as proportional viability (%) by comparing the group treated with the tested compound with the untreated cells, the viability of which is assumed to be 100%.
- HT29 human colon cancer cell line The spheroid formation potential of HT29 human colon cancer cell line was evaluated in 3D nonadherent culture condition. Initially the HT29 human cells were grown as a monolayer after which they were counted, re- suspended and plated with 1,500 cells per well in a 96-well plate pre-coated with a thin layer of 1.5% agarose (w/v) in McCoy's 5A medium containing 10% FBS and incubated at 37°C in a humidified atmosphere of 5% C02. Cell culture media was replaced every 2-3 days with fresh medium to remove cellular debris and the spheroids that were not well-formed.
- the tested compound was added at various concentrations (0.2, 0.4 and 0.6 mg/ml) and incubated for 24, 48 and 72 h. The number and diameter of colonies within each well were photographed and counted every day under the microscope (Olympus BX-51 ; Olympus, Hamburg, Germany), and the images of the representative fields were captured. Each sample was analyzed in triplicate, and all the experiments were performed three times. The viability of cells growing on the spheroids was measured by the APH (acid phosphatase) assay, which was performed according to manufacturer's instructions.
- APH acid phosphatase
- PCR Quantitative polymerase chain reaction
- Immunoblot analysis was performed using antibodies against GAPDH (1:6000 dilution; abl289l5, Abeam), E-cadherin (1: 10000 dilution; ab40772, Abeam), GLUT-4 (1:1000 dilution; G4048, SIGMA), and then species-specific HRP-labeled secondary antibodies were added.
- the blots were visualized using enhanced chemiluminescence (biological industries) and quantitated using ImageQaunt LAS 4000 mini, General Electric).
- Tested compounds were evaluated for their ability to influence on cell viability and proliferation.
- a broad screening was performed using ten different cell lines as described in table 1, and four different concentrations were used (37.5, 75, 150 and 300mM) to treat cells for 24 hours and determine the proliferation inhibitory profile of each novel chemical entity.
- This molecule showed a substantial effect in decreasing cell viability on pancreatic (Aspcl) and lung (A549) cancer cell lines.
- a concentration of 150mM reduced cell viability by around 50% in both cell lines.
- compound 10 was capable to significantly reduce cell viability of MiaPaca
- pancreatic cells pancreatic cells
- T98G cells T98G cells (51.5% with 150mM) which are derived from a relatively resistant brain tumor.
- Normal human skin/foreskin-derived fibroblasts (HFF) were barely influenced by compound 10 (around 80% with 150mM), indicating the specificity of this molecule in treating cancer cells.
- Compound 1 is structurally very similar to compound 2, the only difference between these compounds are two hydroxyl moieties (OH) as compound 1 has quercetin in the polyphenol position instead of Naringenin (see compounds’ stmcture described hereinabove).
- This small modification barely alters the decrease in viability of Aspcl cells when comparing the treatment with compound 2 (56%) to compound 1 (62.5%).
- this modification grants to this novel entity a high specificity to HepG2 cells, leading to a remarkable reduction in cell viability (21%) when these cells were treated with 150mM of compound 1 for 24 hours in comparison to healthy cells (HFF) where there was almost no effect (90% of viability).
- Compound 8 is composed of quercetin linked to p-coumaric acid by a long chain molecule namely aminocapryic acid (see structure defined hereinabove). This compound was effective in reducing viability in Aspcl cells (52% viability with 150mM) with similar strength as the other molecules mentioned above (1, 2 and 10). Nonetheless, this novel entity was able to significantly reduce cell viability (62%) in U87MG, another brain cancer cell line.
- Compound 11 is structurally similar to compound 10. Instead of quercetin in the polyphenol position, compound 11 has a molecule of Naringenin (see structure defined hereinabove). Despite the high similarity, it was only able of reducing cell viability in Aspcl cells in a very moderate fashion (80% viability with 150mM). Regarding the other entities shown in table 1 (compounds 3-6 and 9), no significant results in cell viability were observed.
- a real time cytotoxicity detection assay of Aspcl treated with compounds 2 or 10 was performed during the course of 72 hours on Aspcl cells after treatment with compounds 2 or 10.
- Aspcl cells treated with compounds 2 or 10 for 24 hours at various doses (18-300mM) results in a significant decrease on cell viability in a time and dose-dependent manner, nonetheless, apoptotic bodies were not identified by microscopy analysis ( Figure 1A), indicating that probably treated cells are inducing cell cycle arrest and stopping proliferation instead of inducing death by apoptosis.
- Aspcl cells were incubated with a non-toxic dye that binds to the DNA of died or damage cells. After 24 hours of incubation, cells were treated with compound 1 or 2. The effect observed in cells treated with compound 10 was immediately, after 30 minutes of treatment the measurement of the fluorescence of died cells achieved its maximum level and persists constant until the end of the assay (70 hours after cells seeding) ( Figure 2, grey). Compound 2 exhibits a similar pattern only that its effect was more delayed and moderate ( Figure 2, black).
- MTT viability assay was performed with the cells at the end point of the real-time cytotoxic detection assay in order to confirm the results ( Figure 1B). The level of the fluorescence signal was correlated with the viability level.
- the small GTPases of the RHO subfamily are signaling molecules that are primarily involved in several critical cellular processes, including cell proliferation, motility, and invasion (Bishop, L. A. et al.;Biochem. J. 2000. 348 part 2, 241-255). Recent reports revealed that the activity of RHO protein could be modulated by a functional interaction with catenin pl20, which is found in cytosolic pools. Moreover, it was demonstrated that cadherins could titrate out pl20 molecules from the cytosol, reducing their ability to affect RHO signaling (Anastasiadis, P. Z. et al. J. Cell Sci. 2000, 113 pt.
- ROS reactive oxygen species
- ROS in cancer are involved in cell cycle progression and proliferation, cell survival and apoptosis, energy metabolism, cell morphology, cell-cell adhesion, cell motility, angiogenesis and maintenance of tumor sternness.
- ROS levels are still higher than those observed in normal cells.
- cancer cells may be more sensitive than normal cells to the accumulation of ROS, which offers an interesting therapeutic window (Liu, J. et ak; Oxid. Med. Cell. Longev. 2015, 294303).
- Targeting the enhanced antioxidant mechanisms and directly increasing ROS to reach a threshold that is incompatible with cell viability can selectively kill cancer cells, without affecting normal cells (Sosa, V. et ak; Ageing Res. Rev. 2013, 12, 376-390; and Gorrini, C. et al; Nat. Rev. drug Discov. 2013, 12, 931-947).
- the cellular assays described above were performed in a monolayer system. Although monolayer systems partially reflect the microenvironment of cancer cells, there are currently more advanced culture methods that mimic in a better way the cellular interactions by the cells comprising the tumor (Freidrich, J. et. al.; Nat. Prot. 2009, 4, 309-324). Seeking to elucidate whether the compounds of this invention would also be able to hinder the growth of cancer cells, it was decided to proceed with assays in a 3D cell spheroid model. This assay can be applied to test whether the compounds treatment is able of impairing tumors formation or alternately to test the effect of the treatment in growing tumors.
- FIT-29 cell line was used for this model due to its capacity to form spheroids in vitro.
- Single dose (150mM) treatment of compound 10, 24 hours after cells seeding (before spheroid formation) did not significantly impair tumor formation
- compound 10 avoided secondary tumors formation (Figure 5).
- T98G subcutaneous tumors were less stable and spontaneously started to reduce after one week from cell injection, even without any treatment.
- evaluation of the effect of tumor reduction between control and treated groups was performed at week 1 of treatment ( Figure 14).
- no necrosis was observed, and the percentage of NK cells was similar in both groups.
