Description

[0001] Methods and Compositions for Targeted Protein Degradation RELATED APPLICATIONS This application claims priority to PCT Application No. PCT / CN2024 / 083433, filed on March 23, 2024. The entire contents of the foregoing application are expressly incorporated herein by reference. BACKGROUND Despite advances, treatment of cancer with chemotherapeutic agents remains disappointing. Cancer patients treated with chemotherapeutic agents endure debilitating regimens and often a poor prognosis. This is because the effectiveness and / or application of chemotherapeutic agents containing toxic moieties is reduced by unwanted side effects due to off target or systemic toxicity. The ability to concentrate chemotherapeutics agents in tumor tissue while reducing normal tissue exposure may greatly reduce off target toxicity and improve overall clinical outcomes. Cancer is characterized by aberrant protein expression and activity. HSP90 (heat shock protein 90 kDa) is a molecular chaperone that facilitates the 3-dimensional folding and maintenance of a significant portion of the proteins that signal for cellular growth including many oncogenes (Trepel J. et al, Nat Rev Cancer. 2010, 10:537-49; Birbo B. et al, Int J Mol Sci., 2021, 22:10317). Cancer cells exist in tumor microenvironments characterized by reduced blood flow, high interstitial pressure, hypoxia and acidosis. To mitigate these conditions that negatively affect overall protein stability, cancer cells overexpress HSP90 and even secrete it extracellularly (Lang BJ et al, Int J Mol Sci. 2019, 20:4507; Taha EA et al, Int J Mol Sci. 2019, 20:4588). Moreover, HSP90 chaperone activity is greatly enhanced in cancer cells due to the abundance of mutated or misfolded proteins (Lacey T, Lacey H, Cancer Treat Res Commun. 2021, 28:100400). Cancer specific post-translational modification and protein-protein interaction states also affect HSP90 chaperone activity (Backe SJ et al, J Biol Chem. 2020, 295:11099-11117). In cancer cells this elevated expression and enhanced chaperone activity results in increased binding of HSP90 to small molecule drugs that target its N-terminal ATP-binding. This is in contrast to normal, non-proliferating cells that do not possess elevated levels of HSP90 expression or activity (Kamal A et al., Nature. 2003425:407-10; Moulick K et al, Nat Chem Biol. 2011, 7:818-26). Due to these differences, HSP90 drugs exhibit a chaperone retention effect by concentrating in tumor tissue, while cleared from normal tissue. Camptothecin analogs such as irinotecan, exatecan and SN-38 are antineoplastic agents that inhibit DNA topoisomerase I (Topo I) activity and prevent the relaxation of supercoiled DNA during DNA replication and RNA transcription (Pommier Y, Nat Rev Cancer. 2006, 6:789–802). These agents are commonly used in chemotherapeutic regimen to treat colorectal, pancreatic, small lung and gastric cancers along with pediatric sarcomas (Fujita K et al, World J Gastroenterol. 2015, 21:12234–12248; Rubinson DA et al, Hematol Oncol Clin North Am. 2015, 29:761–776; Levy B et al, JNCCN. 2013, 11:780–787; Mahipal A et al, JNCCN. 2015, 13:1281–1291; Yohe ME et al, Cancer Treat Res Commun. 2021, 28:100400). However, these agents present problems with bioavailability and off target toxicity (Venditto VJ, Simanek ES, Mol Pharm. 2010, 7:307-49). Accordingly, the need exists for chaperone retention effect drug conjugates (CREDCs) that effectively target and concentrate antineoplastic agents such as camptothecin analogs into tumor tissue.

Uses, Formulation and Administration Compounds and compositions described herein are generally useful as anticancer therapies. The terms "cancer" or "tumor" are well known in the art and refer to the presence, e.g., in a subject, of cells possessing characteristics typical of cancer-causing cells, such as uncontrolled proliferation, immortality, metastatic potential, rapid growth and proliferation rate, decreased cell death / apoptosis, and certain characteristic morphological features. Cancer cells are often in the form of a solid tumor. However, cancer also includes non-solid tumors, e.g., blood tumors, e.g., leukemia, wherein the cancer cells are derived from bone marrow. As used herein, the term "cancer" includes pre-malignant as well as malignant cancers. Cancers include, but are not limited to, acoustic neuroma, acute leukemia, acute lymphocytic leukemia, acute myelocytic leukemia (monocytic, myeloblastic, adenocarcinoma, angiosarcoma, astrocytoma, myelomonocytic and promyelocytic), acute T-cell leukemia, basal cell carcinoma, bile duct carcinoma, bladder cancer, brain cancer, breast cancer, bronchogenic carcinoma, cervical cancer, chondrosarcoma, chordoma, choriocarcinoma, chronic leukemia, chronic lymphocytic leukemia, chronic myelocytic (granulocytic) leukemia, chronic myelogenous leukemia, colon cancer, colorectal cancer, craniopharyngioma, cystadenocarcinoma, diffuse large B-cell lymphoma, Burkitt's lymphoma, dysproliferative changes (dysplasias and metaplasias), embryonal carcinoma, endometrial cancer, endotheliosarcoma, ependymoma, epithelial carcinoma, erythroleukemia, esophageal cancer, estrogen-receptor positive breast cancer, essential thrombocythemia, Ewing's tumor, fibrosarcoma, follicular lymphoma, germ cell testicular cancer, glioma, heavy chain disease, hemangioblastoma, hepatoma, hepatocellular cancer, hormone insensitive prostate cancer, leiomyosarcoma, liposarcoma, lung cancer, lymphagioendotheliosarcoma, lymphangiosarcoma, lymphoblastic leukemia, lymphoma (Hodgkin and non-Hodgkin), malignancies and hyperproliferative disorders of the bladder, breast, colon, lung, ovaries, pancreas, prostate, skin, and uterus, lymphoid malignancies of T-cell or B-cell origin, leukemia, lymphoma, medullary carcinoma, medulloblastoma, melanoma, meningioma, mesothelioma, multiple myeloma, myelogenous leukemia, myeloma, myxosarcoma, neuroblastoma, non-small cell lung cancer, oligodendroglioma, oral cancer, osteogenic sarcoma, ovarian cancer, pancreatic cancer, papillary adenocarcinomas, papillary carcinoma, pinealoma, polycythemia vera, prostate cancer, rectal cancer, renal cell carcinoma, retinoblastoma, rhabdomyosarcoma, sarcoma, sebaceous gland carcinoma, seminoma, skin cancer, small cell lung carcinoma, solid tumors (carcinomas and sarcomas), small cell lung cancer, stomach cancer, squamous cell carcinoma, synovioma, sweat gland carcinoma, thyroid cancer, Waldenstrom's macroglobulinemia, testicular tumors, uterine cancer, and Wilms' tumor.

"Solid tumor," as used herein, is understood as any pathogenic tumor that can be palpated or detected using imaging methods as an abnormal growth having three dimensions. A solid tumor is differentiated from a blood tumor such as leukemia. However, cells of a blood tumor are derived from bone marrow; therefore, the tissue producing the cancer cells is a solid tissue that can be hypoxic. "Tumor tissue” or “tumorous tissue" are understood as cells, extracellular matrix, and other naturally occurring components associated with the solid tumor. A specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of a compound described herein in the composition will also depend upon the particular compound in the composition.

LCMS (ESI): RT=1.380 min, m / z found 939.2[M+H]+. Biological Assays Cell lines The following cancer cell lines were employed: MIA PaCa-2 human pancreatic carcinoma (ATCC, #CRL-1420); MV4-11 human biphenotypic B myelomonocytic leukemia (ATCC, #CRL-9591); HCT-116 human colon carcinoma (ATCC, #CRL-247). Cell lines were cultured essentially according to ATCC recommendations. HSP90α-binding fluorescent polarization (FP) assay Binding of test compounds to HSP90α (HSP90AA1) protein was measured by fluorescent polarization (FP) using the HSP90α (N-terminal) Assay Kit (BPS Bioscience, #50298), following the manufacturer’s instructions, except as noted. Fluorescently labeled HSP90-binding compound FITC-geldanamycin (5 nM final concentration) was provided and employed. A 2.5-fold serial dilution of each test compound ranging from 20 μM to 5.2 nM was assayed for binding to HSP90α. After the final step of adding HSP90a protein to each assay well, plates were mixed by brief shaking, incubated at 25°C for 120 min, and fluorescence was measured using a PerkinElmer EnVision Plate Reader. Background- subtracted mP values were calculated from raw data and a four-parameter “log[inhibitor] vs. response” curve was fitted and IC50 values (the concentration at which 50% of the maximal inhibition occurs) calculated using GraphPad Prism 7 software. Results are shown in Table 1. Table 1 CellTiter-Glo® Reagent cancer cell line proliferation assays Cells were plated in 96-well tissue culture plates at 4,000 cells / well and incubated at 37°C / 5% CO2for 72 hr in 100 μl of media. 3-fold serial dilutions of each test compound were prepared ranging from 20 μM to 1.02 nM. MIA Paca-2 cells (human pancreatic cancer cell line), MV4-11 cells (biphenotypic B-myelomonocytic leukemia), and HCT116 (human colorectal carcinoma cell line) were then treated with test compounds at various concentrations with a final concentration of 0.5% DMSO / well, and then incubated at 37°C / 5% CO2 for 24 hr. 100 μl of CellTiter-Glo® Reagent (Promega Corporation, Madison, WI) was added to each well and processed according manufacturer’s protocol. Results were analyzed and IC50-values were calculated in GraphPad 7 software. Results are shown in Table 2. A. IC50<100 nM; B. IC50=100-1000 nM; C. IC50>1000 nM. Table 2

[0009] Plasma Stability Test compounds were prepared in DMSO at 1 mM and 1 mM propantheline or mevinolin working solutions were prepared in acetonitrile. Propantheline served as a positive control for human, dog, rat, and mouse plasma, while mevinolin was used a positive control for rat plasma. Assay plates were prewarmed at 37°C for 15 minutes before adding 398 µL of plasma. Then 2 µL of 1mM test compound and 2 µL of 1mM control compound were added to 398 µL of plasma to reach a final concentration of 5 µM for the test compound and 5 µM for the control compound. The final concentration of organic solvents was 0.5 %. Each assay was performed in duplicate. Plasma samples were incubated at 37°C. Aliquots of 50 µL of each plasma sample were then taken at 0, 1, 2, 4, 8 and 24 hours. The reaction was halted by the addition of 450 µL cold methanol with 5% formic acid containing internal standards. All samples were vortexed for 10 minutes, followed by centrifugation at 3,220 g for 30 minutes to precipitate proteins. From each sample 100 μL of supernatant was transferred to a new plate. Sample supernatants were diluted with ultrapure water and loaded on to a liquid chromatography mass spectrometer. Samples were analyzed by LC-MS / MS. All calculations were carried out using Microsoft Excel. Peak area ratios were determined from extracted ion chromatograms. Percent compounds remaining at each time point were calculated by the following equation: Remaining Percentage t min (%) = (Peak Area Ratio t min / Peak Area Ratio 0 min) *100. Where Peak Area Ratio t min is peak area ratio of control and test compounds at t min; Peak Area Ratio 0 min is peak area ratio of control and test compounds at zero time point. The slope value, k, was determined by linear regression of the natural logarithm of the remaining percentage of the parent drug vs. incubation time curve. Results are shown in Table 3. Table 3
