Abstract
Description
[Technical field]
[0001] Disclosed herein are novel bifunctional compounds formed by the conjugation of a BTK inhibitor moiety and an E3 ligase ligand moiety, which function to recruit targeted proteins to an E3 ubiquitin ligase for degradation, and methods for their preparation and use. [Background technology]
[0002] Proteolysis-inducing chimeric molecules (PROTACs) are a novel strategy for selectively knocking down target proteins with small molecules (Sakamoto KM et al., Proc Natl Acad Sci 2001, 98:8554-9.; Sakamoto KMet al., Methods Enzymol. 2005; 399:833-847.). PROTACs utilize the ubiquitin-protease system to target specific proteins in cells and induce their degradation (Zhou P. et al., Mol Cell. 2000; 6(3):751-756; Neklesa TKet al., Pharmacol Ther. 2017; 174:138-144; Lu M. et al., Eur J Med Chem. 2018; 146:251-259;). The normal physiological function of the ubiquitin-protease system is responsible for the clearance of denatured, mutated or harmful proteins in cells. The ubiquitin-proteasome system (UPS), also known as the ubiquitin-proteasome pathway (UPP), is a common post-translational regulatory mechanism responsible for protein degradation in normal and pathological conditions (Ardley H. et al., Essays Biochem. 2005, 41, 15-30; Komander D. et al., Biochem. 2012, 81, 203-229; Grice GL et al., Cell Rep. 2015, 12, 545-553; Swatek KNet al., Cell Res. 2016, 26, 399-422). Ubiquitin, which is highly conserved in eukaryotic cells, is a modified molecule consisting of 76 amino acids that covalently attaches to and labels target substrates through a cascade of enzymatic reactions involving E1, E2, and E3 enzymes. The modified substrates are then recognized by the 26S proteasome complex for ubiquitination-mediated degradation. To date, two E1 enzymes have been discovered, designated UBA1 and UBA6. On the other hand, there are about 40 E2 enzymes and more than 600 E3 enzymes that provide functional diversity and govern the activity of many downstream protein substrates.However, only a limited number of E3 ubiquitin ligases have been successfully hijacked for use by small molecule PROTAC technology: von Hippel-Lindau tumor suppressor protein (VHL), mouse double minute 2 homolog (MDM2), cellular inhibitor of apoptosis (cIAP), and cereblon (Philipp O. et al., Chem. Biol. 2017, 12, 2570-2578).
[0003] Bifunctional compounds consisting of a target protein binding moiety and an E3 ubiquitin ligase binding moiety have been shown to induce proteasome-mediated degradation of selected proteins. These drug-like molecules offer the possibility of temporally controlling protein expression and could be useful as biochemical reagents for treating diseases.In recent years, this newly developed method has been widely used in antitumor research (Lu J.et al.,Chem Biol.2015;22(6):755-763;Ottis P.et al.,Chem Biol.2017;12(4):892-898.;Crews CMet al.,J Med Chem.2018;61(2):403-404;Neklesa TKet al.,Pharmacol Ther.2017,174:138-144.;Cermakova K.et al.,Molecules,2018.23(8).;An S.et al.,EBioMedicine,2018.;Lebraud H.et al.,Essays Biochem.2017;61(5):517-527.;Sun YHet al.,Cell Res.2018;28:779-81;Toure M.et al.,Angew Chem Int Ed Engl.2016;55(6):1966-1973;Yonghui Sun et al.,Leukemia,volume 33,pages2105-2110(2019);Shaodong Liu et al.,Medicinal Chemistry Research,volume 29, pages 802-808 (2020); patent publications such as US20160045607, US20170008904, US20180050021, US20180072711, WO2002020740, WO2014108452, WO2016146985, WO2016149668, WO2016149989, WO2016197032, WO20 16197114, WO2017011590, WO2017030814, WO2017079267, WO2017182418, WO2017197036, WO2017197046, WO2017197051, WO2017197056, WO2017201449, WO2017211924, WO2018033556, and WO2018071606.
[0004] Bruton's tyrosine kinase (Btk) belongs to the Tec tyrosine kinase family (Vetrie et al., Nature 361:226-233, 1993; Bradshaw, Cell Signal. 22:1175-84, 2010). Btk is mainly expressed in many hematopoietic cells, such as B cells, mast cells, and macrophages (Smith et al., J. Immunol. 152:557-565, 1994), and is localized in bone marrow, spleen, and lymph node tissues. Btk plays an important role in the B cell receptor (BCR) and FcR signaling pathways involved in B cell development and differentiation (Khan, Immunol. Res. 23:147, 2001). Btk is activated by upstream Src family kinases. Once activated, Btk then phosphorylates PLC gamma, resulting in effects on B cell function and survival (Humphries et al., J. Biol. Chem. 279:37651, 2004). These signaling pathways must be tightly regulated. Mutations in the gene encoding Btk cause an inherited B cell-specific immunodeficiency disease known as X-linked agammaglobulinemia (XLA) in humans (Conley et al., Annu. Rev. Immunol. 27:199-227, 2009). Aberrant BCR-mediated signaling can result in dysregulation of B cell activation, leading to several autoimmune and inflammatory diseases. Preclinical studies have shown that Btk-deficient mice are resistant to the development of collagen-induced arthritis. Furthermore, clinical studies of Rituxan, a CD20 antibody that depletes mature B cells, have revealed a critical role for B cells in several inflammatory diseases, such as rheumatoid arthritis, systemic lupus erythematosus, and multiple sclerosis (Gurcan et al., Int. Immunopharmacol. 9:10-25, 2009). Thus, Btk inhibitors can be used to treat autoimmune and / or inflammatory diseases.
[0005] Inhibition of BTK has been shown to affect cancer development (B cell malignancies) and cell survival, and to ameliorate autoimmune diseases (e.g., rheumatoid arthritis and lupus). Inhibition of BTK via alternative strategies, such as by degradation of BTK, has also been reported (Alexandru D.et al.,Biochemistry 2018,57,26,3564-3575;Adelajda Z.et al.,PNAS 2018 115 (31);Dennis D.,et al.,Blood,2019,133:952-961;Yonghui S.et al.,Cell Research,2018,28,779-781;Yonghui S.et al.,Leukemia,2019,Degradation of Bruton's tyrosine kinase mutants by PROTACs for the potential treatment of ibrutinib-resistant non-Hodgkin lymphomas), and are disclosed or discussed in patent publications, such as US20190276459, WO2019186343, WO2019186358, WO2019148150, WO2019177902, and WO2019127008.

Chromatography may involve any number of methods, including, for example: reversed and normal phase; size exclusion; ion exchange; high-pressure, medium-pressure and low-pressure liquid chromatography methods and equipment; small-scale analytical; simulated moving bed ("SMB") and preparative thin or thick layer chromatography, as well as small-scale thin layer and flash chromatography techniques. The skilled artisan will apply the technique most likely to achieve the desired separation.
[0095] "Diastereomer" refers to stereoisomers of a compound that have two or more chiral centers, but are not mirror images of one another. Diastereomeric mixtures can be separated into their individual diastereomers based on their physical or chemical differences, by methods well known to those skilled in the art, such as chromatography and / or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with a suitable optically active compound (e.g., a chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers, and converting the individual diastereomers into the corresponding pure enantiomers (e.g., by hydrolysis). Enantiomers and diastereomers can also be separated by using chiral HPLC columns.
[0096] Single stereoisomers, e.g., substantially pure enantiomers, can be obtained by resolving the racemic mixture using methods such as forming diastereomers using optically active resolving agents (Eliel, E. and Wilen, S. Stereochemistry of Organic Compounds. New York: John Wiley & Sons, Inc., 1994; Lochmuller, C.H., et al. "Chromatographic resolution of enantiomers: Selective review." J. Chromatogr., 113(3) (1975): pp. 283-302). Racemic mixtures of chiral compounds of the present invention can be separated and isolated by any suitable method, including (1) forming ionic diastereomeric salts with chiral compounds and separating them by fractional crystallization or other methods, (2) forming diastereomeric compounds with chiral derivatizing agents, separating the diastereomers, and converting them to pure stereoisomers, and (3) directly separating substantially pure or enriched stereoisomers under chiral conditions.

[0098] In addition, if the compounds disclosed herein are obtained as acid addition salts, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, such as a pharma- ceutically acceptable addition salt, can be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid according to conventional procedures for preparing acid addition salts from base compounds.
