c-MYC mRNA TRANSLATION MODULATORS AND USES THEREOF

IN THE TREATMENT OF CANCER

FIELD OF THE INVENTION

[001] The present invention relates to novel c-MYC mRNA translation modulators, composition and methods of preparation thereof, and uses thereof in the treatment of cancer.

BACKGROUND OF THE INVENTION

[002] Cancer is the second most co on cause of death in the United States, exceeded only by heart disease. In the United States, cancer accounts for 1 of every 4 deaths. The 5-year relative survival rate for all cancer patients diagnosed in 1996-2003 is 66%, up from 50% in 1975-1977 ( Cancer Facts & Figures American Cancer Society: Atlanta, GA (2008)). The rate of new cancer cases decreased by an average 0.6% per year among men between 2000 and 2009 and stayed the same for women. From 2000 through 2009, death rates from all cancers combined decreased on average 1.8% per year among men and 1.4% per year among women. This improvement in survival reflects progress in diagnosing at an earlier stage and improvements in treatment. Discovering highly effective anticancer agents with low toxicity is a primary goal of cancer research.

[003] The Myc family includes three major members, the proto-oncogene c-Myc (cellular Myelocytomatosis, short Myc), as well as L-myc and N-myc. These three Myc homologs are involved in the early stages of carcinogenesis and metastatic spread in most human cancers. In most types of tumors Myc gene is not mutated or duplicated, but its mRNA and/or protein levels are increased, indicating that in cancer Myc overexpression is induced at the level of transcription, mRNA steady state levels and translation. Indeed, myc gene expression normally depends on growth factor signaling and both myc mRNA and Myc protein have very short half-lives (of 30 and 20 min respectively) [Dang, C. V. (2012). MYC on the path to cancer. Cell 149, 22-35]. In tumor cells however, the cellular levels of Myc become independent from such signaling and regulation, and the resulting exacerbated Myc function drives intracellular and extracellular transcription programs that allow tumors to grow and thrive. However, Myc does not necessarily need to be overexpressed in order for a cancer to be highly dependent upon its activity. A study from Soucek et al. (Nature (2008) 455(7213):679-83) shows that tumors that express c-Myc at endogenous levels exhibit tumor regression upon Myc inhibition via a genetically engineered system. Therefore, treatment with a Myc inhibitor is not necessarily limited to cancers that overexpress Myc. Compounds according to this invention may also be used to regulate the translation of Myc mRNA, wherein the direct target for the compounds is a protein or RNA which regulate Myc mRNA translation, and as such any tumor which is Myc dependent will benefit from the therapeutic utility of these compounds. [004] Due to its extensive pathogenic significance, MYC is an important anticancer target. Deregulated Myc gene is found in a wide range of human hematological malignancies and solid tumors, especially in breast cancer, ovarian carcinoma, acute myeloid leukemia, chronic myelogenous leukemia, Hodgkin’s and Burkitt’s lymphoma, diffuse large Bcell lymphoma, prostate cancer, colon cancer, gastric cancer, primary central nervous system lymphoma, glioblastoma, medulloblastoma, melanoma, non small cell lung carcinoma, germinal center-derived lymphomas, esophageal squamous cell carcinoma, osteosarcoma, bladder cancer, pancreatic cancer and lung adenocarcinoma. Recent studies also indicate that deregulation of c-MYC is related to the occurrence of BRAF V600E thyroid cancers, choroid plexus carcinoma, and colitis-associated cancer. In addition, amplification of the MYC gene was found in a significant number of epithelial ovarian cancer cases. In TCGA datasets, the amplification of Myc occurs in several cancer types, including breast, colorectal, pancreatic, gastric, and uterine cancers. [005] Although Myc gene is a very important oncogene and considered as a driver in carcinogenesis and MYC protein is a key transcription factor broadly targeting various genes, rational designing a direct Myc inhibitor is still challenging. This is mainly because MYC protein lacks structural regions amenable to therapeutic inhibition by small molecules and is considered an undruggable target [BioDrugs (2019) 33:539-553]

[006] Designing and developing MYC modulators is challenging, primarily because the MYC protein has a disordered structure which lacks a pocket or groove that can act as a binding site for modulators. Interfering with the MYC transcription, blocking the protein-protein interaction (PPI) of MYC and its cofactors, and influencing on signaling pathways related to MYC were used in the past as potential modulatory targets, but failed to be developed as drug candidates. Myc PPI inhibitors failed to show sufficinet efficacy in cell-based assays and animal models due to the requirement of high target occupancy to drive efficacy. Modulators of signaling pathways upstream to myc, for example mTOR modulators, failed due lack of target specificity.

[007] Nevertheless, a therapeutic approach to target c-Myc has remained elusive. The absence of a clear ligand-binding domain establishes a formidable obstacle toward direct inhibition, which is a challenging feature shared among many compelling transcriptional targets in cancer. Thus, alternative modalities that target Myc are required, as outlined herein, namely compounds which regulate Myc mRNA translation.

[0015] Figure 1 demonstrates how Protein Synthesis Monitoring (PSM) specifically monitors c-Myc synthesis. The assay system comprises human non-small cell lung carcinoma cell line A549, which is expressing high level of c-Myc. Two tRNAs (di-tRNA) which decode one specific glutamine codon and one specific serine codon were transfected with control RNAi or an RNAi directed to c-Myc. The FRET signal specifically monitors c-Myc translation, as the FRET signal in c-Myc siRNA treated cells was inhibited. In blue, cell nuclei stained with DAPI; in yellow, FRET signals from tRNA pair which decodes glutamine-serine di-codons. [0016] Figure 2 depicts selective regulation of c-Myc translation. The panel demonstrates metabolic labeling in A549 cells, treated with vehicle, general translation inhibitor cycloheximide or anti-c-Myc compound. Treatment with cycloheximide resulted in total inhibition of global protein synthesis, while treatment with tested compound showed no significant effect. In gray, cell nuclei stained with DAPI; in yellow, L-Azidohomoalanine (AHA) metabolic labeling.

In some embodiments the cancer is invasive. In some embodiments the cancer is metastatic cancer. In some embodiments the cancer is advanced cancer. In some embodiments the cancer is drug resistant cancer.

[00189] In various embodiments “metastatic cancer” refers to a cancer that spread (metastasized) from its original site to another area of the body. Virtually all cancers have the potential to spread. Whether metastases develop depends on the complex interaction of many tumor cell factors, including the type of cancer, the degree of maturity (differentiation) of the tumor cells, the location and how long the cancer has been present, as well as other incompletely understood factors. Metastases spread in three ways - by local extension from the tumor to the surrounding tissues, through the bloodstream to distant sites or through the lymphatic system to neighboring or distant lymph nodes. Each kind of cancer may have a typical route of spread. The tumor is called by the primary site (ex. breast cancer that has spread to the brain is called metastatic breast cancer to the brain).

[00190] In various embodiments “drug-resistant cancer” refers to cancer cells that acquire resistance to chemotherapy. Cancer cells can acquire resistance to chemotherapy by a range of mechanisms, including the mutation or overexpression of the drug target, inactivation of the drug, or elimination of the drug from the cell. Tumors that recur after an initial response to chemotherapy may be resistant to multiple drugs (they are multidrug resistant). In the conventional view of drug resistance, one or several cells in the tumor population acquire genetic changes that confer drug resistance. Accordingly, the reasons for drug resistance, inter alia, are: a) some of the cells that are not killed by the chemotherapy mutate (change) and become resistant to the drug. Once they multiply, there may be more resistant cells than cells that are sensitive to the chemotherapy; b) Gene amplification. A cancer cell may produce hundreds of copies of a particular gene. This gene triggers an overproduction of protein that renders the anticancer drug ineffective; c) cancer cells may pump the drug out of the cell as fast as it is going in using a molecule called p-gly coprotein; d) cancer cells may stop taking in the drugs because the protein that transports the drug across the cell wall stops working; e) the cancer cells may learn how to repair the DNA breaks caused by some anti-cancer drugs; f) cancer cells may develop a mechanism that inactivates the drug. One major contributor to multidrug resistance is overexpression of P-gly coprotein (P-gp). This protein is a clinically important transporter protein belonging to the ATP-binding cassette family of cell membrane transporters. It can pump substrates including anticancer drugs out of tumor cells through an ATP-dependent mechanism; g) Cells and tumors with activating RAS mutations are relatively resistant to most anti-cancer agents. Thus, the resistance to anticancer agents used in chemotherapy is the main cause of treatment failure in malignant disorders, provoking tumors to become resistant. Drug resistance is the major cause of cancer chemotherapy failure.

[00191] In various embodiments “resistant cancer” refers to drug-resistant cancer as described herein above. In some embodiments “resistant cancer” refers to cancer cells that acquire resistance to any treatment such as chemotherapy, radiotherapy or biological therapy.

[00192] In various embodiments, this invention is directed to treating, suppressing, reducing the severity, reducing the risk, or inhibiting cancer in a subject, wherein the subject has been previously treated with chemotherapy, radiotherapy or biological therapy.

[00193] In various embodiments “Chemotherapy” refers to chemical treatment for cancer such as drugs that kill cancer cells directly. Such drugs are referred as "anti-cancer" drugs or "antineoplastics." Today's therapy uses more than 100 drugs to treat cancer. To cure a specific cancer. Chemotherapy is used to control tumor growth when cure is not possible; to shrink tumors before surgery or radiation therapy; to relieve symptoms (such as pain); and to destroy microscopic cancer cells that may be present after the known tumor is removed by surgery (called adjuvant therapy). Adjuvant therapy is given to prevent a possible cancer reoccurrence.

[00194] In various embodiments, “Radiotherapy” (also referred herein as “Radiation therapy”) refers to high energy x-rays and similar rays (such as electrons) to treat disease. Many people with cancer will have radiotherapy as part of their treatment. This can be given either as external radiotherapy from outside the body using x-rays or from within the body as internal radiotherapy. Radiotherapy works by destroying the cancer cells in the treated area. Although normal cells can also be damaged by the radiotherapy, they can usually repair themselves. Radiotherapy treatment can cure some cancers and can also reduce the chance of a cancer coming back after surgery. It may be used to reduce cancer symptoms. [00195] In various embodiments “Biological therapy” refers to substances that occur naturally in the body to destroy cancer cells. There are several types of treatment including: monoclonal antibodies, cancer growth inhibitors, vaccines and gene therapy. Biological therapy is also known as immunotherapy.

[00196] When the compounds or pharmaceutical compositions of the present invention are administered to treat, suppress, reduce the severity, reduce the risk, or inhibit a cancerous condition, the pharmaceutical composition can also contain, or can be administered in conjunction with, other therapeutic agents or treatment regimen presently known or hereafter developed for the treatment of various types of cancer. Examples of other therapeutic agents or treatment regimen include, without limitation, radiation therapy, immunotherapy, chemotherapy, surgical intervention, and combinations thereof.

[00197] In various embodiments, the compound according to this invention, is administered in combination with an anti-cancer therapy. Examples of such therapies include but are not limited to: chemotherapy, immunotherapy, radiotherapy, biological therapy, surgical intervention, and combinations thereof.

[00198] In various embodiments, the compound is administered in combination with an anti-cancer agent by administering the compounds as herein described, alone or in combination with other agents. [00199] In various embodiments, the composition for cancer treatment of the present invention can be used together with existing chemotherapy drugs or be made as a mixture with them. Such a chemotherapy drug includes, for example, alkylating agents, nitrosourea agents, antimetabolites, antitumor antibiotics, alkaloids derived from plant, topoisomerase inhibitors, hormone therapy medicines, hormone antagonists, aromatase inhibitors, P-glycoprotein inhibitors, platinum complex derivatives, other immunotherapeutic drugs, and other anticancer agents. Further, they can be used together with hypoleukocytosis (neutrophil) medicines that are cancer treatment adjuvant, thrombopenia medicines, antiemetic drugs, and cancer pain medicines for patient's QOL recovery or be made as a mixture with them.

[001017] Compounds activity was tested in tumor cell lines expressing c-Myc by using high content image analysis. c-Myc mRNA rate of translation was assays using PSM assay, c-Myc protein levels and intracellular localization were assayed by immunofluorescence using a c-Myc specific antibody and c-Myc mRNA levels and intracellular localization was tested using specific fluorescent probes, as detailed in the Experimental Methods below (Example 6). The di-tRNA translation rate measurement specificity to c-Myc was shown by co-transfecting c-Myc specific siRNA. Transfection of labelled di-tRNA with c-Myc specific siRNA reduced the FRET signal originating from ribosome translating c-Myc, relative to cells transfected with nonrelevant siRNA (Figure 1).

[001018] Compounds did not affect global translation. A549 cells were incubated with active compounds and metabolically labelled with fluorescent methionine for a 4 hour pulse (click-chemistry modified methionine). Cells were fixed and newly synthesized proteins detected by using click-chemistry with a fluorescent detector (Figure 2). Global ribosome inhibitor, cycloheximide (CHX) completely reduced incorporation of modified methionine (Figure 2, compare middle and left panels). However, a reperentative compound did not inhibit incorporation of modified methionine, indicating that global translation is not affected by the compounds (Figure 2, compare right and left panels, respectively).

[001019] Compounds reduced c-Myc protein accumulation in A549 cells without affecting c-Myc transcription. A549 cells were incubated with compounds for 24 hours (Figure 3, upper panel) and c-Myc protein detected by immunofluorescence. In parallel, A549 cells were incubated with compounds for 4 hours and c-Myc mRNA was visualized by micrscopy using c-Myc mRNA specific fluorescent-tagged probes (Figure 3, lower panel). Both a general transcription inhibitor, Actinomycin D, and compounds of the invention, reduced c-Myc protein (Figure 3, upper panel). Actinomycin D inhibited transcription site (Figure 3, middle lower panel, spots inside the nucleus) and mRNA accumulation in the cytoplasm (Figure 3, middle lower panel, spots in the cytoplasm). However, compound treated cells did not affect transcription site intensity or number (Figure 3, right lower panel, spots inside the nucleus are evident), but did affect steady state levels of mRNA in the cytoplasm (Figure 3, right lower panel, reduction of spots in the cytoplasm relative to DMSO control). This indicates that compounds of the invention affect c-Myc steady state mRNA levels, either by affecting turn over rate of c-Myc mRNA, or by inhibiting its recruitment by ribosomes.

[001020] A549 human non-small cell lung carcinoma cells were treated for 24 hours with increasing compound concentration, cells were fixed and stained with a nuclei stain (DAPI) and anti-c-Myc fluorescent antibody. The c-Myc signal was quantified by image analysis, and data was exported and analyzed using TIBCO Spotfire® (TIBCO Corporation). Dose response curves were generated and fitted with logaristic regression to calculate potency (ECso values). Potency values are presented in Table 2 for all compounds and are shown for selected compounds (Figure 4).

[001021] NMRI nude female mice of 6-8 weeks of age were acclimated after shipping for > 4 days. A549 cells, 5 x 10 ⁶ in 100 ul MatrigekPBS (50:50), were subcutaneously injected into flanks of mice. When the tumor size reached 80 to 200 mm ³ , mice were grouped with similar average tumor size in each group, 10 animals per group. Compounds were dissolved in 10% DMSO, 10% Solutol, 80% water. Compounds were given i.p. for 49 days at 3 mg/kg twice a week. Caliper measurement of tumor size was done twice a week.

[001022] Compound 332 inhibited c-Myc-dependent tumor growth in-vivo. Figure 5 shows the relative tumor volumes of A549 xenografts in NMRI female nude mice after they were treated with compound 332, 3 mg/kg, twice a week, for 49 days. Error bars represent median ± SEM, n = 10 mice at each time point and analyzed by one-tailed T-TEST in Prism for *p < 0.05.

False positive and toxic compounds were eliminated. A total of 3,307 compounds were identified as hits, compounds which increased or decreased the FRET signal generated by ribosomes during c-Myc translation.

[001024] Positive hits were re-screened in the specific PSM assay, using tRNAgln and tRNAser. Hits were scored using Anima’s proprietary algorithms, and 348 compounds, which selectively inhibited c-Myc synthesis in specific PSM assay, were selected as confirmed hits. These compounds were purchased as powder to confirm activity. Re-purchased hits were tested in the specific PSM assay (tRNAgln-tRNAser) and anti-c-Myc immunofluorescence, and in counter assays to eliminate global translation modulators: (1) bulk tRNA and (2) metabolic labeling using Click-IT™ AHA (L-Azidohomoalanine).

Cell culture

[001025] A549 cells (ATCC ^® CCL-185 ^™ ) were maintained in DMEM low glucose medium (Biological Industries, Cat. 01 -050-1 A), containing 10% fetal bovine serum, 1% L-glutamine and 1% penicillin- streptomycin solution.

[001026] SK-N-F1 cells (ATCC ^® CRL-2142 ^™ ) were maintained in DMEM high glucose medium (Biological Industries, Cat. 01-055-1A), containing 10% fetal bovine serum, 2% L-glutamine, 1% penicillin-streptomycin solution, 1% sodium pyruvate and 1% non-essential amino acids.

Specific tRNA ( tRNA isoacceptor ) isolation and labeling

[001027] The specific tRNAgln (TTG) and tRNAser (CGA) were isolated for from baker’s yeast (Roche) using biotinylated oligos complimentary to sequences encompassing the D-loop and anti-codon. The biotinylated oligos were mixed with total yeast tRNA and heated up to 82 °C for 10 min, followed by addition of TMA buffer (20mM Tris, pH 7.6,1.8M tetramethylammonium chloride, 0.2mM EDTA). The mixture was incubated at 68°C for 10 min, and annealed by slow cooling to 37°C. tRNA:DNA oligo mixture then was incubated with streptavidin linked agarose beads at room temperature for 30 min while shaking. Unbound tRNA and tRNA:DNA complexes were removed by centrifugation and beads washed with lOmM Tris-HCl (pH 7.6). The target tRNA was eluted from the resin by incubation at 45°C or 55°C for 7 min followed by centrifugation and collection of the supernatant to clean tubes.

[001028] The purity of the isolated tRNA isoacceptors was confirmed using fluorescent polarization assay. Purified tRNA was annealed to a complementary oligo tagged at the 3 ’-end with Cy3. The annealed purified tRNA isoacceptor FP signal was compared to the signal derived from annealing of a tRNA isoacceptor oligo annealed to the same Cy3-oligo. Samples with more than 80% purity were selected for labeling.

[001029] The dihydrouridines of the target tRNAs or total yeast tRNA were labeled as described in U.S. Pat. No. 8,785,119. Labeled tRNAs were purified by reverse phase HPLC and eluted with an ethanol gradient. Protein synthesis monitoring (PSM) Assays

[001030] Cy3 and Cy5 Labeled tRNA, bulk or specific, were transfected with 0.4 mΐ HiPerFect (Qiagen) per 384 well. First, HiPerFect was mixed with DMEM and incubated for 5 min; next, 6 nanograms Cy3- labeled tRNAgln and 6 ng Cy5-labled tRNAser (or 9 ng each Cy3 and Cy5-labelled bulk tRNA) were diluted in lxPBS and then added to the HiPerFecfDMEM cocktail and incubated at room temperature for 10 min. The transfection mixture was dispersed automatically into 384-well black plates. Cells were then seeded at 3,500 cells per well in complete culture medium and incubated at 37°C, 5% CO2. Forty-eight hours after transfection compounds were added at a final concentration of 30 mM. Four hours post treatment, cells were fixed with 4% paraformaldehyde and images were captured with Operetta microscope (Perkin Elmer) using x20 high NA objective lens.

Metabolic labeling assay

[001031] A549 cells were seeded at 3,200 cells per well in complete culture medium. Plates were incubated at 37°C, 5% CO2 overnight. After 48 hours of incubation, the growth medium was aspirated, and cells were washed three times with HBSS. Metabolic labeling medium DMEM (-Cys -Met), containing 10% dialyzed FBS, 1 % pencillin-streptomycin and 1 % L-glutamine was added to the cells for 30 min. Then medium was replaced by metabolic labeling medium containing 25 mM L-Azidohomoalanine (AHA, ThermoFisher) and tested compounds at a final concentration of 30 pM, and cells were incubated for 4 hours at 37°C, 5% CO2. Cells were washed by HBSS at 37°C for 15 min before fixing with 4% paraformaldehyde. Cells were washed twice with 3% BSA in PBS before permeabilization with 0.5% Triton X-100 in PBS for 20 min. The AHA staining with Alexa Fluor™ 555 alkyne was performed according to the manufacturer protocol. Images were captured with Operetta microscope (Perkin Elmer) using x20 high NA objective lens. c-Myc immunofluorescence assay

[001032] A549 cells were grown in 384-wells plates (Perkin Elmer, Cat. 6057300) for 48 hours, treated with compounds and then fixed for 20 min in 4% paraformaldehyde. After that permeabilization was done using 0.1% Triton X-100 in PBS for 20 min. Primary anti-c-Myc antibody (Abeam, ab32072) staining was performed for 90 min at room temperature. Cells then were washed twice with PBS and incubated with secondary antibody (Abeam, ab 150075) for 90 min at room temperature. Nuclei were stained with DAPI for 10 min and washed twice with PBS.

[001033] Cell images were taken with Operetta (Perkin Elmer, USA), a wide-field fluorescence microscope at 20x magnification. After acquisition, the images were transferred to Columbus software (Perkin-Elmer) for image analysis. In Columbus, cells were identified by their nucleus, using the “Find Nuceli” module and cytoplasm was detected based on the secondary antibody channel. Subsequently, the fluorescent signal was enumerated in the identified cell region. Then data was exported to a data analysis and visualization software, Tibco Spotfire, USA. Fluorescent In Situ Hybridization (FISH) assay

[001034] A549 cells were grown in 384-wells plates (Perkin Elmer, Cat. 6057300) for 48 hours, treated with compounds for 4 hours and then fixed for 20 min in 4% paraformaldehyde. Next day, permeabilization was done for 90 min at 4°C, using 70% ethanol. Then, the cells were incubated for 10 min with 10% formamide in 10% saline-sodium citrate. Fluorescently labeled custome DNA probes that target c-Myc (Cy3, BioSearch Technologies, Cat. SMF-1063-5) and GAPDH (Cy5, BioSearch Technologies, Cat. SMF- 2019-1) mRNAs were hybridized overnight at 37°C in a dark chamber in 10% formamide. The next day, cells were washed twice with 10% formamide for 30 min. Next, nuclei were counterstained with DAPI (SIGMA, Cat. 5MG-D9542) and then cells were washed twice with PBS. FISH experiments were performed according to the probes manufacturer’s protocol for adherent cells.

[001035] Following RNA FISH experiments, images of cells were taken with Operetta (Perkin Elmer, USA), a wide-held fluorescence microscope at x63 magnification. After acquisition, the images were transferred to Columbus software for image analysis. In Columbus, cells were identified by their nucleus, using the “Find Nuceli” module, cytoplasm was detected based on the FISH-channel, and single mRNAs in the cytoplasm and transcription sites in the nucleus were detected using “Find Spots” module. Subsequently, fluorescent signals were collected for each channel in the identified regions: nucleus, cytoplasm and spots. Data was exported to a data analysis and visualization software, Tibco Spotfire, USA. A549 xenograft model in nude mice.

[001036] NMRI nude female mice of 6-8 weeks of age were acclimated after shipping for > 4 days. A549 cells, 5 x 10 ⁶ in 100 ul MatrigekPBS (50:50), were subcutaneously injected into flanks of mice. When the tumor size reached 80 to 200 mm ³ , mice were grouped with similar average tumor size in each group, 10 animals per group. Compounds were dissolved in 10% DMSO, 10% Solutol, 80% water. Compounds were given i.p. for 49 days at 3 mg/kg twice a week. Caliper measurement of tumor size was done twice a week.
