Abstract
Description
[Technical Field]
[0001] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 680,739, filed June 5, 2018, the entire contents of which are incorporated herein by reference.
[0002] The present disclosure relates to methods of using GSK-3β inhibitors, including 3-(5-fluorobenzofuran-3-yl)-4-(5-methyl-5H-[1,3]dioxolo[4,5-f]indol-7-yl)pyrrole-2,5-dione, for the treatment of malignant lymphoproliferative disorders. [Background technology]
[0003] Malignant lymphoproliferative disorders are a group of diseases characterized by abnormal proliferation of lymphocytes. There are two general types of malignant lymphoproliferative disorders: malignant B-cell lymphoproliferative disorders and malignant T-cell lymphoproliferative disorders.
[0004] Malignant B-cell lymphoproliferative disorders include diffuse large B-cell lymphoma, acute lymphocytic leukemia, lymphoblastic-phase chronic myeloid leukemia, chronic lymphocytic leukemia / small lymphocytic lymphoma, extraductal marginal zone B-cell lymphoma, mucosa-associated lymphoid tissue lymphoma, follicular lymphoma, mantle cell lymphoma, nodal marginal zone B-cell lymphoma, Burkitt lymphoma, capillary leukemia, primary central nervous system lymphoma, splenic marginal zone B-cell lymphoma, Waldenstrom's macroglobulinemia / lymphodysplastic lymphoma, multiple myeloma, plasma cell dysplasias, plasma cell neoplasms, primary mediastinal B-cell lymphoma, Hodgkin's disease, and Castelman's disease.
[0005] Malignant T-cell lymphoproliferative disorders include T-cell leukemia / lymphoma, extravascular natural killer / T-cell lymphoma, cutaneous T-cell lymphoma, enteropathic T-cell lymphoma, angioimmunoblastic T-cell lymphoma, anaplastic large T / null cell lymphoma, subcutaneous panniculitis-like T-cell lymphoma, T-cell acute lymphoblastic leukemia, T-cell large-grain lymphocytic leukemia, lymphoblastic-phase chronic myeloid leukemia, post-transplant lymphoproliferative syndrome, and human T-cell leukemia virus type 1 (HTLV-1) positive. + ) Adult T-cell leukemia-lymphoma (ATL), T-cell prolymphocytic leukemia (T-PLL), and T-cell lymphoma not otherwise specified.
[0006] Glycogen synthase kinase-3 (GSK-3) is a serine (S) / threonine (T) kinase originally described as a key regulator of metabolism, particularly glycogen biosynthesis. Embi et al. Glycogen synthase kinase-3 isolated from rabbit skeletal muscle. Furthermore, this kinase has been shown to regulate carbohydrate metabolism through its function. Eur J Biochem. 1980;107:519-27. Since then, it has been shown to play a role in several disease processes, including cancer, aging, immune disorders, metabolic disorders, and neurological disorders, through modulation of many diverse substrates. Sutherland C. What are bona fide GSK3 substrates? Int J Alzheimers Dis. 2011;2011:505-607; Gao C, et al. GSK3: an important target for the development of novel therapies for type 2 diabetes and Alzheimer's disease. Rev Neurosci. 2011;23:1-11; Wang H, et al., Convergence of mammalian target of rapamycin complex 1- and glycogen synthase kinase 3-beta signaling pathways regulates the innate inflammatory response. J Immunol. 2011;186:5217-26; Klamer G, et al. Use of small molecule GSK3beta inhibitors to treat inflammation. Curr Med Chem. 2010;17:2873-81; Henriksen EJ. Dysregulation of glycogen synthase kinase-3 in skeletal muscle and the pathogenesis of insulin resistance and type 2 diabetes. Curr Diabetes Rev. 2010;6:285-93. GSK-3 has two ubiquitously expressed, highly conserved isoforms, GSK-3α and GSK-3β, that share and differ in both substrate and functional effects. Aberrant overexpression of GSK-3β promotes tumor growth and chemotherapy resistance in various solid tumors. However, little is known about the impact of GSK-3β on the development, treatment resistance, and survival of B-cell lymphomas, despite its known function as a metabolic checkpoint regulator in B cells. Jellusova J, et al.GSK3 is a metabolic checkpoint regulator in B cells.Nat Immunol.2017;18:303-12.
[0007] GSK-3β inhibitors are of interest due to their ability to potentially alter the clinical course of GSK-3β-mediated diseases. Some GSK-3β inhibitors include tideglusib, LY2090314, 9-ING-41, CHIR-99021 and CHIR-98014, SB216763 and SB415286, AR-A011418, CG701338, and CG202796. See Amy Walz, Andrey Ugolkov, Sunandana Chandra, et al., Molecular Pathways: Revisiting Glycogen Synthase Kinase-3b as a Target for the Treatment of Cancer, Clin Cancer Res; 23(8) April 15, 2017, OF1-OF7.
[0008] 3-(5-Fluorobenzofuran-3-yl)-4-(5-methyl-5H-[1,3]dioxolo[4,5-f]indol-7-yl)pyrrole-2,5-dione (“9-ING-41”) is a GSK-3β inhibitor having the following chemical structure: [ka]
[0009] The synthesis, properties, and / or biological activity of 9-ING-41 are described in U.S. Pat. No. 8,207,216; Gaisina, et al., From a Natural Product Lead to the Identification of Potent and Selective Benzofuran-3-yl-(indol-3-yl)maleimides as Glycogen Synthase Kinase 3β Inhibitors That Suppress Proliferation and Survival of Pancreatic Cancer Cells, J. Med. Chem. 2009, 52, 1853-1863; and Hilliard, et al., Glycogen synthase kinase 3β inhibitors induce apoptosis in ovarian cancer cells and inhibit in vivo tumor growth, Anti-Cancer Drugs 2011, 22:978-985. 9-ING-41 is reported to be useful in treating certain cancers, including brain, lung, breast, ovarian, bladder, neuroblastoma, kidney, and pancreatic cancers, as well as traumatic brain injury.
[0010] The clinical course of diffuse large B-cell lymphoma (DLBCL) remains variable, despite improved response and survival rates following the addition of the anti-CD20 monoclonal antibody rituximab to standard chemotherapy in the late 1990s. Coiffier B, et al. Long-term outcome of patients in the LNH-98.5 trial, the first randomized study comparing rituximab-CHOP to standard CHOP chemotherapy in DLBCL patients: a study by the Groupe d'Etudes des Lymphomes de l'Adulte. Blood. 2010;116:2040-5; Feugier P, et al. Long-term results of the R-CHOP study in the treatment of elderly patients with diffuse large B-cell lymphoma: a study by the Groupe d'Etude des Lymphomes de l'Adulte. J Clin Oncol. 2005;23:4117-26. Although 60% of patients enjoy long-term disease-free survival, a biologically unfavorable subset of patients has chemotherapy-refractory disease and a less favorable prognosis. Sehn LH, et al. Introduction of combined CHOP plus rituximab therapy dramatically improved outcome of diffuse large B-cell lymphoma in British Columbia. J Clin Oncol. 2005;23:5027-33. In particular, double translocations of c-MYC and BCL-2 in DLBCL, known as "double-hit lymphoma" ("DHL"), have been associated with poor outcomes after standard R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) therapy, with few patients achieving long-term survival.Petrich AM, et al.Impact of induction regimen and stem cell transplantation on outcomes in double-hit lymphoma: a multicenter retrospective analysis.Blood.2014;124:2354-61.

[0041] [Figure 1] Figures 1A–1E show the viability and proliferation of lymphoma cells with 9-ING-41 treatment. 10,000 cells (SUDHL-4 (Figure 1B), KPUM-UH1 (Figure 1C), Karpas 422 (Figure 1D), and TMD8 (Figure 1E)) per 96-well plate well were either untreated or treated with 1 μM 9-ING-41 in triplicate. Cell numbers were calculated using the MTS assay on days 1, 3, 5, and 7. Briefly, 20 μL of MTS reagent was added to the cells, and after 2 h of incubation, the absorbance at 490 nm (A490) was read using a Biotek plate reader. The absorbance at OD = 490 nm increases proportionally to the cell density. Error bars represent the standard deviation between replicates. The viability on day 3 is shown in Figure 1A.

[0106] The following examples further illustrate certain aspects of the present disclosure and are not intended to limit the scope of the disclosure in any way. Materials - Examples 1 to 5
[0107] Daudi (Burkit) and SUDHL-4 (germinal center (GC) diffuse large B-cell lymphoma (DLBCL)) cell lines were purchased from American Type Culture Collection (ATCC). KPUM-UH1 (double-hit DLBCL) cells were obtained from Junya Kuroda of Kyoto Prefectural University of Medicine. All cell lines were cultured aseptically and maintained at 37°C and 5% CO2 in a water-jacketed incubator (Thermo-Forma). They were supplemented with RPMI-1640 (Corning) containing 0.3 g / mL glutamine, 10% FBS (Sigma), and antibiotic and antimycotic reagent (Gemini Bioproducts; final concentrations: 100 units / mL penicillin G, 100 μg / mL streptomycin sulfate, and 250 ng / mL amphotericin B). Karpas 422 (GC-DLBCL) cells were purchased from Sigma. TMD8 (activated B cell (ABC) DLBCL) cells were obtained from the laboratory of Dr. Louis Stoudt at the National Cancer Institute and maintained as described above, but with 20% FBS. All cell numbers for the assay were quantified using a TC20 automated cell counter (BioRad). All lymphoma cell lines tested express active GSK-3β.
[0108] Venetoclax and Idelalisib were purchased from Selleck Chemicals. BAY-1143572 was purchased from Active Biochem. All drugs were resuspended in DMSO. Drug-free DMSO was used as an untreated control. [Example]
[0109] Example 1 - Viability and proliferation assays (MTS assay) Cell viability at day 3 and proliferation over 7 days were measured after treating cells with varying concentrations of 9-ING-41 using Promega CellTiter 96™ AQueous One Solution Cell Proliferation Assay reagent (MTS) according to the manufacturer's instructions. At the end of treatment, 20 μL of reagent was added per well to a 96-well plate and incubated at 37°C for 2-4 hours. Absorbance at 490 nm (A490) was measured using a Powerwave XS plate reader (Biotek).
[0110] All lymphoma cell lines used in this study express active GSK-3β. SUDHL-4, KPUM-UH1, Karpas 422, or TMD8 lymphoma cells were plated and cell numbers were measured on days 1, 3, 5, and 7 using the MTS assay (see Figure 1). Cell viability on day 3 (Figure 1A) was reduced by 40–70% (p<0.05) upon 1 μM 9-ING-41 treatment, with SUDHL-4 and KPUM-UH1 showing the greatest reduction in cell viability. Upon exposure to 1 μM 9-ING-41, all lymphoma cell lines underwent growth arrest (Figure 1B–1E) and showed less than 30% proliferation compared to controls on day 7 (p<0.05). Cell viability of lymphoma cells was also examined with varying concentrations of 9-ING-41 (0.1 μM, 0.5 μM, 1 μM, 5 μM, and 10 μM), and a decrease in viability was observed at concentrations of 9-ING-41 above 0.5 μM. [Example]
[0111] Example 2 - EnzChek® Caspase 3 Assay The EnzChek Caspase 3 Assay (Thermo Fisher Scientific) was performed according to the manufacturer's instructions. 100,000 cells were plated in 12-well plates and treated in duplicate with various concentrations of 9-ING-41 for 24 hours. At the end of treatment, cells were centrifuged at 200 rcf for 5 minutes, washed once with 1X PBS, and lysed in 50 μL of the 1X lysis buffer provided with the kit. For efficient lysis, cells were subjected to one freeze-thaw cycle. Lysed cells were centrifuged again to remove cellular debris, and the supernatant was used for the assay. 50 μL of a 2X substrate working solution containing Z-DEVD-R110 substrate was added to the cell lysate, followed by incubation at room temperature for 45 minutes. The Rhodamin 110-derived substrate (Z-DEVD-R110) used in this assay is a non-fluorescent bisamide compound that, upon enzymatic cleavage via active caspase 3 and possibly caspase 7 in cell lysates, is converted in a two-step process to a fluorescent monoamide, which is then further converted to the fluorescent R110 product. Both of these products were then measured using a Biotek Synergy 2 fluorescent plate reader at the corresponding wavelengths (excitation 496 nm / emission 520 nm). Fluorescence readings were normalized to the protein amount in the cell lysates, as determined via a standard BCA assay (Pierce Thermo Fisher Scientific). Relative fluorescence was calculated after setting the untreated control at 1.
[0112] The ENZCHEK caspase 3 assay revealed increased caspase 3 / 7 activity observed when lymphoma cells were treated with 9-ING-41 at concentrations of 0.5 μM or higher. Pharmacokinetic studies in xenograft mice suggested that intravenous administration of 20 mg / kg resulted in plasma concentrations of approximately 8 μM and brain concentrations of approximately 40 μM within 30 minutes.

[0113] Data from MTS and ENZCHEK caspase-3 assays indicate that 9-ING-41 as a single agent inhibits lymphoma cell line proliferation and reduces lymphoma cell viability. Without intending to be bound by theory, these results suggest that targeting GSK-3β reduces the proliferation and viability of aggressive B-cell lymphoma cell lines and induces divergent effects on survival signaling and DNA damage response, ultimately leading to apoptosis. These effects were independent of the cell origin of the DLBCL cell lines.
[0114] Of particular interest is the activity of 9-ING-41 in the DHL cell line KPUM-UH1, a typical chemotherapy-resistant cell line. Without intending to be bound by theory, Luminex analysis (described below) suggests that 9-ING-41 exerts its effects in KPUM-UH1 cells through downregulation of c-MYC signaling and induction of apoptosis via reduction of survivin. This downregulation of survivin does not appear to be associated with or driven by changes in NF-κB in this cell line. This is in contrast to what has been described in acute lymphoblastic leukemia (ALL), where GSK-3β inhibition sensitizes ALL cells to NF-κB-mediated apoptosis via the effect of survivin. See Hu Y, Gu X, Li R, Luo Q, Xu Y. Glycogen synthase kinase-3β inhibition induces nuclear factor-κB-mediated apoptosis in pediatric acute lymphoblastic leukemia cells. J Exp Clin Cancer Res.2010;29:154.https: / / doi.org / 10.1186 / 1756-9966-29-154. [Example]
[0115] Example 3 - Western Blot Analysis c-MYC levels were analyzed in KPUM-UH1 cells via Western blot after 9-ING-41 alone and in combination with either Venetoclax or BAY-1143572. Approximately 100 million cells were spun down at 200 rcf for 5 min and washed once with PBS before lysing in 50 μl of Millipore Milliplex MAP lysis buffer supplemented with protease and phosphatase inhibitors (Roche). Protein denatured in 4X sample buffer supplemented with β-mercaptoethanol (Bio-Rad) was loaded per well. Bio-Rad stain-free Criterion 4-20% precast gels were used. Gels were run for 90 min at 140 volts, after which the stain-free technology was activated using a Bio-Rad gel imager to visualize the total protein levels loaded in the gel. Proteins were then transferred to membranes using a nitrocellulose turbo transfer pack and system (Bio-Rad). The membranes were blocked for 1 hour with 5% w / v dry milk in Tris-buffered saline 0.1% Tween 20 (TBS-T). The membranes were then incubated overnight with primary antibodies diluted in 5% BSA in 5% TBS-T. The membranes were then washed three times with TBS-T (one 15-minute wash and two 5-minute washes), followed by incubation with the corresponding HRP-conjugated secondary antibodies for 1 hour and subsequent washing with TBS-T as before. After the final wash, the membranes were developed using the Pierce SuperSignal West Pico Chemiluminescence Kit and visualized using a Bio-Rad imaging system. The antibodies used were rabbit anti-GSK-3β (Cell Signaling, Cat. No. 12456), rabbit anti-phospho-GSK-3β (Y216) (Abcam, Cat. No. ab75745), rabbit anti-c-MYC (Cell Signaling, Cat. No. 5605), rabbit anti-c-MYC (Ser 62) (Cell Signaling, Cat. No. 13748), rabbit anti-c-MYC (Thr 58) (Abcam, Cat. No. ab185655), and mouse anti-β-actin (Sigma, Cat. No. A5441) diluted 1:1000.Anti-rabbit HRP and anti-mouse HRP secondary antibodies were purchased from Cell Signaling and used at a 1:5000 dilution. Where necessary, membranes were stripped with RESTORE PLUS Western Blot Stripping Buffer (Pierce) for 10 minutes, washed several times with TBS-T, and then reblocked and reprobed as before. Quantification of band intensity was performed using Image J software (NIH). These experiments in the double-hit lymphoma cell line KPUM-UH1 suggest that 9-ING-41 treatment modifies phospho-c-MYC. [Example]
[0116] Example 4 - Luminex analysis Alterations in NF-κB signaling [MILLIPLEXMAP NF-κB Signaling Magnetic Bead Kit 6-plex Kit, EMD Millipore, analytes: c-MYC, FADD (Ser194), IκBα (Ser32), IKKα / β (Ser177 / Ser181), NF-κB (Ser536), TNFR1], DNA damage [MILLIPLEXMAP DNA Damage / Genotoxicity Magnetic Bead Panel, EMD Millipore, analytes: ATR (total), Chk1 (Ser345), Chk2 (Thr68), H2A.X (Ser139), MDM2 (total), p21 (total), p53 (Ser15)], and apoptotic pathways [Bio-plex pro RBM apoptosis panel 2 and The levels of [Bad, Bax / Bcl-2 dimer, Bcl-xL, Bim, Mcl-1, active caspase 3, Bcl-xL / Bak dimer, Mcl-1 / Bak dimer, and survivin] in cells treated with 1 μM 9-ING-41 for 48 h compared with untreated controls were determined using Luminex multiplex technology on a FLEXMAP 3D instrument according to the manufacturer's instructions. Cells were lysed in MILLIPLEX MAP Lysis buffer supplemented with protease inhibitor cocktail (Sigma) and phosphatase inhibitor cocktails 2 and 3 (Sigma). After BCA protein quantification, 15 μg of protein was added to each well. All samples were run in duplicate. Changes in MFI or absolute amounts between 9-ING-41-treated cells and untreated controls were analyzed, and non-logarithmic t-tests were used to determine statistical significance.
[0117] Analysis of NF-κB signaling revealed a significant decrease in total c-MYC levels in Karpas 422 and TMD8 cell lines, while the remaining cell lines showed only a trend toward a decrease in this protein. DNA damage signaling via assessment of p-H2A.X (Ser139) was found to be increased in SUDHL-4 and Karpas 422 cell lines (both p<0.05). Furthermore, a significant increase in phospho-p53 (Ser15) upon 9-ING-41 treatment was observed in SUDHL-4 and TMD8 cells. Analysis of apoptotic signaling pathways revealed a significant decrease in survivin (~2-fold, p<0.05) and an increase in active caspase-3 in all lymphoma cell lines except TMD8. All lymphoma cell lines, except KPUM-UH1, showed a significant decrease (~2-fold, p<0.05) in Mcl-1 / Bak dimers, whereas Bcl-xl / Bak dimer expression showed a significant decrease (~1.5-fold, p<0.05) in all cell lines except TMD8. [Example]
[0118] Example 5 - Combination Dose Response Daudi, SUDHL-4, KPUM-UH1, Karpas 422, or TMD8 cells were simultaneously treated with a series of concentrations of 9-ING-41 (0 μM, 0.05 μM, 0.5 μM) and either Venetoclax (0 nM, 0.05 μM, 0.5 μM, 5 nM, 5 nM, 50 nM, 500 nM, 5000 nM), BAY-1143572 (0 μM, 0.005 μM, 0.05 μM, 0.5 μM, 5 μM, 50 μM), or Idelalisib (0 μM, 0.005 μM, 0.05 μM, 0.5 μM, 5 μM, 50 μM). See Figure 2. Viability at day 3 using the MTS assay was determined as described above. Background absorbance was subtracted from the A490 of the samples, and the relative A490 of the remaining samples was calculated, with the A490 of the vehicle / untreated control set at 1. IC50 was calculated as the fold change in IC50 of the novel drug when combined with 0.5 μM of 9-ING-41.
[0119] As shown in Figure 3, combination therapy with 9-ING-41 and a second therapeutic agent can reduce the amount of the second therapeutic agent required to produce a given therapeutic effect. As shown, combination treatment of the SUDHL-4 cell line with 0.5 μM 9-ING-41 demonstrated an 8-fold decrease in the IC50 value of Venetoclax. Similarly, when the KPUMUH1 cell line was combined with 0.5 μM 9-ING-41, the IC50 value of Venetoclax was reduced 2-fold. Combination treatment of the SUDHL-4 cell line with 0.5 μM 9-ING-41 resulted in an 8-fold decrease in the IC50 value of BAY-1143572. Combination treatment with 9-ING-41 did not significantly alter the IC50 value of idelalisib in the cell lines examined.
[0120] Materials and Methods—Examples 6-11 Such research is not intended to involve patient input. This lymphoma spore biospecimen protocol is in accordance with the Declaration of Helsinki and was approved by the Mayo Clinic Institutional Review Board. All primary patient samples were biopsied tissue from the spleen or lymph nodes. Fresh tissue samples were gently dissociated into cell suspensions and subjected to Ficoll-Paquet density gradient centrifugation. Primary lymphoma cells were then used directly in proliferation assays or stored at -80°C for later Western analysis after lymphoma diagnosis was confirmed.
[0121] All lymphoma cell lines used in this study were purchased from ATCC (Manassas, VA) or DSMZ (Braunschweig, Germany). DLBCL (diffuse large B-cell lymphoma) lines were cultured in IMDM medium supplemented with 10% human serum (Sigma-Aldrich); TCL (T-cell non-Hodgkin's lymphoma) and MCL (mantle cell lymphoma) lines were maintained in RPMI-1640 medium supplemented with 10% fetal calf serum. The Jeko cell line used for mouse xenograft modeling was stably transduced with Firefly luciferase (Fluc) by lentiviral transduction. Cell lines were routinely checked for mycoplasma infection and authenticated by in-house SNP-based PCR or short tandem repeat profiling by ATCC.
[0122] Antibodies and other reagents Common reagents were from Sigma-Aldrich. Antibodies for immunoblotting, including anti-human GSK3α (Cat#4337), GSK3β (Cat#12456), and phospho-GSK3α-S21 / GSK3β-S9 (Cat#9327), were purchased from Cell Signaling. Mouse anti-GSK3β monoclonal antibody (clone 7 / GSK3β, Cat#610201, BD Biosciences), anti-α-tubulin antibody (clone MD1A, Cat#T9026), and rabbit anti-pericentrin antibody (Cat#ab4448) used for immunofluorescence were purchased from Sigma and Abcam, respectively. Alexa 488- or Alexa 565-conjugated secondary antibodies were from Life Technologies.
[0123] Apoptosis assay Cells were plated in 24-well plates at 5x10 5 Cells were seeded at 1000 x g / well and incubated with the indicated concentrations of 9-ING-41 for 48 h. Cells were then stained with FITC-conjugated Annexin V (Life Technologies) and propidium iodide, followed by analysis on a BD FACS Calibur flow cytometer.
[0124] dna cell cycle Cells were fixed and permeabilized with cold ethanol, treated with RNase, and stained with propidium iodide (Sigma). Stained cells were run on a BD FACS Calibur using CELLQuest PRO software (Becton Dickinson). Data were analyzed using FlowJo vX software (Tree Star Inc.).
[0125] Proliferation assay Cells were plated in a 96-well plate at 1x10 4 Cells / well were seeded and incubated with the indicated concentrations of 9-ING-41 for 48 hours, then pulsed overnight with tritiated thymidine before being analyzed for thymidine incorporation.
[0126] Western immunoblotting Western analysis was performed on a LI-COR Odyssey CLX imager using the LI-COR reagent system as previously described and developed.
[0127] quantitative PCR Total mRNA from lymphoma cell lines was isolated using the RNAeasy kit (Qiagen), and cDNA was synthesized using the Superscript III cDNA Synthesis Kit (Life Technologies). RT-PCR was then performed on an ABI 7500 Real-Time PCR System (Applied Biosystems). 2 qPCR was performed using SYBR Green ROX qPCR Mastermix (Qiagen).
[0128] Drug IC 50 Calculation of The IC50 of 9-ING-41 on cell survival and proliferation was calculated using an online IC50 calculation tool (https: / / www.aatbio.com / tools / ic50-calculator / ).
[0129] Immunohistochemical staining Immunohistochemistry (IHC) on 5-µm-thick paraffin sections was performed according to standard protocols. Tissue sections on slides were deparaffinized with xylene and rehydrated through a series of alcohols. Antigen retrieval was performed with citrate buffer (pH 6.0). Endogenous peroxidase was quenched with 30% hydrogen peroxide. Slides were incubated with anti-GSK3b antibody (BD, 1:150) for 2 hours at room temperature, washed three times with Tris-buffered saline (5 minutes each), and then incubated with biotinylated anti-mouse secondary antibody (1:200) for 1 hour at room temperature. Slides were treated with HRP-conjugated ABC complex (Vectastain, Vector Laboratories) for 1 h at room temperature, then developed with 3,39-diaminobenzidine (DAB, Vector Laboratories), counterstained with methylene blue, mounted with DPX, and examined and imaged under a Nikon Eclipse Ti microscope.
[0130] Immunofluorescence staining for centrosome and spindle localization of GSK3β For co-immunostaining of GSK3β and pericentrin in the centrosome (Figures 8C-8J), we used a partial fixation method by fixing cells on cytospin slides in 3% paraformaldehyde in PBS for 5 minutes at room temperature. Cells were then permeabilized with 0.2% Triton X-100 in PBS for 10 minutes, blocked with 5% BSA in PBS for 1 hour, and immunostained with mouse anti-GSK3β mAb and rabbit anti-pericentrin overnight at 4°C. Cells were then washed and further stained with fluorochrome-conjugated secondary antibodies.
[0131] All other immunostaining of GSK3β and α-tubulin on cytospin preparations of lymphoma cells was performed using 4% paraformaldehyde in PBS for 15 min at room temperature, followed by permeabilization and the same staining steps as above. Cells were analyzed and imaged using a conventional Zeiss microscope or a Zeiss LSR 780 confocal microscope. [Example]
[0132] Example 6. GSK3α and GSK3β are overexpressed in lymphoma cells. We examined the expression of GSK3α and GSK3β in purified human normal B and T cells and DLBCL, MCL, and TCL lymphoma cell lines. RT-qPCR revealed that GSK3α and GSK3β mRNA expression levels were high but variable in most lymphoma cell lines, compared with low expression in normal lymphocytes (Figure 4A). Western blot analysis of GSK3 protein expression revealed that GSK3α protein was strongly expressed in most lymphoma cell lines (except Ly-19), whereas its expression was weak in B and T lymphocytes (Figure 4B, green). Similarly, GSK3β protein was also strongly expressed in all lymphoma cell lines, but very weakly expressed in normal lymphocytes (visible after prolonged exposure; not shown) (Figure 4B, red). These data indicate that GSK3 protein is overexpressed in most B- and T-lymphoma cell lines.
[0133] Western blots showed that both GSK3α and GSK3β proteins were variably phosphorylated across our panel of lymphoma cell lines, as well as in normal lymphocytes. [Example]
[0134] Example 7. GSK3α and GSK3β are functionally important in lymphoma cells. Given that both GSK3α and GSK3β are overexpressed in lymphoma cells and that both enzymes participate in multiple signaling pathways important for cellular function, we investigated whether GSK3α and GSK3β functionally support lymphoma cell survival and proliferation. Treatment of TCL and MCL lines with low doses of 9-ING-41 for 48 h induced apoptosis (Figure 5A); DLBCL lines required higher concentrations (Figure 5B). In contrast, even at a concentration of 10.0 μM, no significant apoptosis was detected in purified normal unstimulated T lymphocytes or peripheral blood mononuclear cells. The inhibitory concentrations of 9-ING-41 at half the maximal effect (IC50) on cell viability of various lymphoma cell lines were calculated (Table 1). [Table 1]
[0135] 9-ING-41 can specifically induce apoptosis in lymphoma cells without affecting normal lymphocytes. To investigate the role of GSK3 in lymphoma cell proliferation, thymidine incorporation assays were performed in the presence or absence of 9-ING-41. The proliferation rates of all TCL and MCL lines were significantly suppressed at concentrations as low as 1.0 μM with 9-ING-41. DLBCL lines required slightly higher concentrations. The IC values of 9-ING-41 on cell proliferation of various lymphoma cell lines were 50 was calculated (Table 1). These data indicate that GSK3 activity is important for lymphoma cell proliferation and survival.
[0136] The GSK3A and GSK3B genes were genetically deleted using CRISPR / CAS9 knockout technology.
[0137] Additionally, guide RNAs (gRNAs) targeting the first coding exons of both GSK3α and GSK3β genes were designed using a web tool (http: / / crispr.mit.edu / ). The gRNA sequences (GSK3α: GACAGATGCCTTTCCGCCGC; GSK3β: CGGCTTGCAGCTCTCCGCAA) were cloned into the px458 vector (Addgene) co-expressing GFP. The constructs were nucleofected into lymphoma cells using a nucleofection kit (Lonza, Basel, Switzerland). 36 hours post-nucleofection, GFP-expressing single cells were sorted into 96-well plates at 1 cell / well on an Aria II FACS sorter. After 2 weeks of culture, each subclone was genotyped by PCR and Sanger DNA sequencing.
[0138] After transient expression of constructs carrying CAS9-T2A-GFP and gRNA-specific GSK3A or GSK3B gene exon 1 sequences, single cells expressing GFP were selected by flow sorting into 96-well plates. After 2–3 weeks of culture, single-cell subclones harboring specific modifications of GSK3A, GSK3B, or both genes were genotyped for gene deletion and verified by Western blot for protein deficiency. As summarized in Table 2, several GSK3A null knockout subclones were readily obtained from all five cell lines tested, and GSK3B null subclones were also obtained from the Ly-1 cell line. However, no knockout subclones were detected when 24–36 single-cell subclones were analyzed from the Ly-19, Jeko, Mino, and Karpas 299 cell lines. CRISPR / CAS9 was a highly efficient approach for Baytril deletion of the GSK3B gene in Ly-1 cells (19 / 24, 79%), but given that there were no GSK3B-null clones in the other lymphoma cell lines tested (0 / 24, 0 / 24, 0 / 36, 0 / 26, 0%), these data support the conclusion that GSK3B is required for lymphoma cell survival in these cell lines. Similar results were observed using shRNA knockdown, showing that GSK3B knockdown was lethal in several lymphoma cell lines except for Ly-1. [Table 2]
[0139] Example 7. GSK3 inhibition blocks G2 / M progression in lymphoma cells. We investigated the effect of 9-ING-41 on lymphoma cell cycle dynamics. Following 9-ING-41 treatment, a cell cycle block at G2 / M was observed in all lines tested after just 24 hours of treatment (Figure 6A), indicating that GSK3 activity is required for successful progression through mitosis. To further determine whether this G2 / M arrest was specifically due to GSK3β inhibition, we examined the cell cycle profiles of parental (wild-type), GSK3A, GSK3B, and GSK3A / B knockout Ly-1 subclones. Without treatment, parental wild-type and GSK3A null Ly-1 subclones displayed normal cell cycle profiles, whereas GSK3B and GSK3A / B knockout subclones showed an increase in cells in G2 / M (Figure 6B). Furthermore, the GSK3A / B double knockout subclones also showed an increase in polymorphic (>4N) cells, likely due to mitotic failure. These cell cycle defects in GSK3B-null and GSK3A / B-null Ly-1 cells are likely mediated by compensatory mechanisms inherent to the Ly-1 cell line and have little impact on the survival of Ly-1 progeny. 9-ING-41 treatment phenocopied the effects of GSK3B single or GSK3A / B double deletion on cell cycle progression, indicating that GSK3B is important for lymphoma cell cycle G2 / M progression and that 9-ING-41 is a potent cell cycle blocker for lymphoma cells. [Example]
[0140] Example 8. GSK3 inhibition arrests lymphoma cells at a pre-mitotic stage. Although cells arrested in G2 / M appear as a single DNA content (4N) peak on flow cytometry histograms (Figure 6A), there are actually at least five consecutive steps (M1-M5) in G2 / M that are critical for successful cell division. These include prophase (M1, chromosome condensation, initiation of mitotic spindle formation), prometaphase (M2, nuclear envelope breakdown, centrosome polarization), metaphase (M3, chromosome pairs align at the midplane), anaphase (M4, separation of daughter chromosomes), telophase (M5, reformation of daughter nuclei), and finally cytokinesis (separation of the two daughter cells). Each of these discrete steps has a unique, distinguishable nuclear morphology on Wright-stained cells (depicted in Figure 7A). To determine at which stage cells become arrested, we examined the morphology of untreated and 9-ING-41-treated JeCHO cells. As shown in Figure 7B (left panel), all M1-M5 mitotic stages were easily identified in untreated Jeco cells, whereas in 9-ING-41-treated cells (right panel), the majority of cells displayed condensed chromosome morphology and reduced cytoplasmic staining resembling protophase (M1) cells, with no identifiable cells with M2-M5 morphology. By differential counting of 100 mitotic cells, all stages of mitotic cells (M1-M5) were found to be easily identifiable in untreated cells; in 9-ING-41-treated mitotic cells, only protophase (M1) cells were identified (Figure 7C). Similar results were observed in other lymphoma lines, including DHL-6, Ly-3, Mino, and Karpas299. These observations support the conclusion that GSK3 activity is required for mitotic progression.

[0141] Example 9. GSK3β localizes to the centrosome and mitotic spindle in lymphoma cells. We investigated the involvement of GSK3β in two key prophase events, centrosome polarization and mitotic spindle formation. We examined the subcellular localization of GSK3β protein in interphase Jeko or Ly-1 cells by immunofluorescence staining. During interphase, GSK3β was prominently localized in the nucleus in Jeko cells and in centrosome-like paired dots in the cytoplasm (Figure 8A-B). To further demonstrate that these cytoplasmic paired dots are indeed centrosomes, we first stained wt Ly-1 cells for GSK3β protein and pericentrin, a centrosome marker, using an incomplete fixation protocol. We found that the cytoplasmic GSK3β dots perfectly colocalized with pericentrin (Figure 8D-8F). Furthermore, anti-GSK3β antibody staining was shown to be specific for GSK3β protein in GSK3B-null Ly1 cells (Figure 8G-J). From this, we concluded that GSK3β is localized to the centrosome and nucleus in interphase cells.
[0142] To determine the subcellular localization of GSK3β in mitotic cells, we analyzed the localization of GSK3β in normal mitotic JECO cells. GSK3β staining (green, Figure 8K-L) revealed a "fireworks-like" pattern with a centrally polarized centrosome and the mitotic spindle and microtubules extending outward. α-Tubulin showed a similar staining pattern to GSK3β (red, Figure 8M-N), suggesting that GSK3β localizes to microtubules during mitosis. These results suggest that GSK3β specifically localizes to the centrosome and mitotic spindle during mitosis. We also determined the localization of GSK3β in JECO cells treated with 9-ING-41 (Figure 8Q-R). A similar fireworks-like GSK3β staining pattern was observed in all protophase cells without any changes in GSK3β localization. Collectively, these data indicate that GSK3β localizes to centrosomes and the nucleus during interphase (Fig. 8A-B) and to centrosomes and mitotic microtubules during mitosis (Fig. 8K-L). Treatment with 9-ING-41 did not alter the localization of GSK3β, nor did it affect centrosome polarization or microtubule formation. [Example]
[0143] Example 10. Expression and targeting of GSK3 in primary cells from lymphoma patients We examined the expression of GSK3α and GSK3β proteins in freshly isolated primary lymphoma cells from patients with MCL, high-grade B-cell lymphoma, follicular lymphoma grade 3B, DLBCL, or angioimmunoblastic TCL. All five samples showed enhanced expression of GSK3α and GSK3β proteins compared with normal blood B-cell controls (Figure 9A). These patient cells also responded similarly to the antiproliferative effects of 9-ING-41 (Figure 9B). Paraffin samples from another cohort of patients with various types of lymphoma were probed by IHC for GSK3β protein expression. As shown in Figure 9C, overexpression of GSK3β was observed in all samples, with varying intensities. RNA-Seq analysis of primary DLBCL patient samples obtained from the public database of Gene Expression Profile Interactive Analysis (http: / / gepia.cancerpku.cn) also demonstrated increased expression of GSK3α and GSK3β in lymphomas compared with normal lymphocytes.
[0144] We analyzed a cohort of 234 DLBCL patients with clinical survival data (median follow-up 10.5 years (95% CI: 7.9-not reached)) from recently published RNA-Seq data (Schmitz R, Wright GW, Huang DW, et al. Genetics and Pathogenesis of Diffuse Large B-Cell Lymphoma. N Engl J Med. 2018;378(15):1396-1407). Receiver operating characteristic (ROC) curve analysis was performed to dichotomize GSK3α and GSK3β expression and establish optimal cutoff values for high and low expression (10.5 for GSK3α and 8.6 for GSK3β). The OS was significantly higher (p=0.03) in patients with high GSK-3α expression (≥10.5, n=172) than in those with low GSK-3α expression (<10.5, n=62), at 7.8 years (95% OS: 7.2-8.4). Similarly, the OS was significantly higher (p=0.03) in patients with high GSK-3β expression (≥8.6, n=170) than in those with low GSK-3β expression (<8.6, n=62), at 7.8 years (95% OS: 7.2-8.2) and 9.7 years (95% OS: 8.6-11.5). These results suggest that overexpression of either GSK-3α or GSK-3β correlates with poorer clinical outcomes. Furthermore, the grouping data also showed that the majority of DLBCL patients segregated into either GSK3α or GSK3β high expression groups, further validating the conclusion that GSK3α and GSK3β are commonly overexpressed in lymphomas.

[0145] Example 11. Targeting GSK3 in mouse xenografts of human lymphoma An MCL xenograft mouse model was established by subcutaneously injecting NGS mice with Jeco cells expressing the firefly luciferase reporter gene Fluc.
[0146] NSG (NOD.Cg-PrkdcscidIl2rgtm1Wjl / SzJ) mice used in these experiments were purchased from The Jackson Laboratory (Bar Harbor, ME). Eight to ten 8-week-old mice of the same sex were subcutaneously injected with 5 x 10 Fluc-expressing Jeko cells in the right flank. Tumor implantation was confirmed by imaging 4 days after Jeko cell inoculation. Tumor-implanted mice were randomly grouped into control and treatment groups and subsequently untreated or treated with 9-ING-41 via IP injection as indicated. Tumor volume was measured with an IVIS imager (Xenogen, Alameda, CA) 20 minutes after IP injection of 200 μl of 15 mg / ml D-leuciferin (GoldBio, St. Louis, MO) while anesthetized with 2.5% isoflurane. All imaging parameters were maintained consistent for comparability. The experiment was terminated when the largest tumor met the size limit of the IACUC protocol.
[0147] In two independent experiments, 8 and 10 mice bearing implanted tumors confirmed by imaging (usually 4 days after tumor inoculation) were randomly assigned to either control or 9-ING-41 treatment 40 mg / kg IP every other day (Figure 10A). As shown in Figure 10B, mice in the control (untreated) group had large tumors with significant luciferase activity by day 17; however, 9-ING-41-treated mice had small tumors with much lower luciferase activity. These data demonstrated that 9-ING-41 has single-agent antitumor activity in a mouse model of MCL. [Example]
[0148] Example 12 Treatment of Diffuse Large B-Cell Lymphoma (DLBCL) with 9-ING-41 A human with diffuse large B-cell lymphoma was given 9-ING-41 at 1 mg / kg daily in six 21-day cycles. After treatment, the patient's DLBCL went into remission. [Example]
[0149] Example 13 Treatment of Mantle Cell Lymphoma (MCL) with 9-ING-41
[0150] Humans suffering from mantle cell lymphoma were given 9-ING-41 at 3 mg / kg daily for six 21-day cycles. After treatment, the human's MCL went into remission. [Example]
[0151] Example 14 Treatment of T-cell lymphoma (TCL) with 9-ING-41 A human suffering from T-cell lymphoma (non-Hodgkin's) is given 9-ING-41 at 2 mg / kg per day for six 21-day cycles. After treatment, the human's T-cell lymphoma goes into remission.
