Disclosed herein are novel bifunctional compounds formed by conjugating EGFR inhibitor moieties with E3 ligase Ligand moieties, which function to recruit targeted proteins to E3 ubiquitin ligase for degradation, and methods of preparation and uses thereof.
Proteolysis targeting chimera (PROTAC) consists of two covalently linked protein-binding molecules: one capable of engaging an E3 ubiquitin ligase, and another that binds to the protein of interest (POI) a target meant for degradation (Sakamoto K M et al., Proc. Natl. Acad. Sci. 2001, 98: 8554-9; Sakamoto K. M. et al., Methods Enzymol. 2005; 399:833-847). Rather than inhibiting the target protein's enzymatic activity, recruitment of the E3 ligase to the specific unwanted proteins results in ubiquitination and subsequent degradation of the target protein by the proteasome. The whole process of ubiquitination and proteasomal degradation is known as the ubiquitin-proteasome pathway (UPP) (Ardley H. et al., Essays Biochem. 2005, 41, 15-30; Komander D. et al., Biochem. 2012, 81, 203-229; Grice G. L. et al., Cell Rep. 2015, 12, 545-553; Swatek K. N. et al., Cell Res. 2016, 26, 399-422). Proteasomes are protein complexes which degrade unneeded, misfolded or abnormal proteins into small peptides to maintain health and productivity of the cells. Ubiquitin ligases, also called an E3 ubiquitin ligase, directly catalyze the transfer of ubiquitin from the E2 to the target protein for degradation. Although the human genome encodes over 600 putative E3 ligases, only a limited number of E3 ubiquitin ligases have been widely applied by small molecule PROTAC technology: cereblon (CRBN), Von Hippel-Lindau (VHL), mouse double minute 2 homologue (MDM2) and cellular inhibitor of apoptosis protein (cIAP) (Philipp O. et al., Chem. Biol. 2017, 12, 2570-2578), recombinant Human Ring Finger Protein 114 (RNF114) (Spradlin, J. N. et al. Nat. Chem. Biol. 2019, 15, 747-755) and DDB1 And CUL4 Associated Factor 16 (DCAF16) (Zhang, X. et al. Nat. Chem. Biol. 2019, 15, 737-746). For example, cereblon (CRBN) forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1) and Cullin-4A (CUL4A) to ubiquitinate a number of other proteins followed by the degradation via proteasomes. (Yi-An Chen, et al., Scientific Reports 2015, 5, 1-13). Immunomodulatory drugs (IMiDs), including thalidomide, lenalidomide, and pomalidomide, function as monovalent promoters of PPIs by binding to the cereblon (CRBN) subunit of the CRL4ACRBN E3 ligase complex and recruiting neosubstrate proteins. (Matyskiela, M. E. et al., Nat Chem Biol 2018, 14, 981-987.) As a consequence, the ability of thalidomide, and its derivatives, to recruit CRBN has been widely applied in proteolysis-targeting chimeras (PROTACs) related studies (Christopher T. et al. ACS Chem. Biol. 2019, 14, 342-347; Honorine L. et al, ACS Cent. Sci. 2016, 2, 927-934). PROTACs have great potential to eliminate protein targets that are “undruggable” by traditional inhibitors or are non-enzymatic proteins. (Chu T T. et al., Cell Chem Biol. 2016; 23:453-461. Qin C. et al., J Med Chem 2018; 61: 6685-6704. Winter G E. et al., Science 2015; 348:1376-1381.) In the recent years, PROTACs as useful modulators promote the selective degradation of a wide range of target proteins have been reported in antitumor studies. (Lu J. et al., Chem Biol. 2015; 22(6):755-763; Ottis P. et al., Chem Biol. 2017; 12(4):892-898; Crews C. M. et al., J Med Chem. 2018; 61(2):403-404; Neklesa T.

Epidermal growth factor receptor (EGFR) that belongs to the ErbB family is a transmembrane receptor tyrosine kinase (RTK), which plays a fundamentally key role in cell proliferation, differentiation, and motility (Y. Yarden, et al., Nat. Rev. Mol. Cell Biol. 2001; 2:127-137). Homo- or heterodimerization of EGFR and other ErbB family members activates cytoplasmic tyrosine kinase domains to initiate intracellular signaling. Overexpression or activating mutations of EGFR are associated the development of many types of cancers, such as pancreatic cancer, breast cancer, glioblastoma multiforme, head and neck cancer, and non-small cell lung cancer (Yewale C., et al. Biomaterials. 2013, 34 (34): 8690-8707). The activating mutations in the EGFR tyrosine kinase domain (L858R mutation and exon-19 deletion) have been identified as oncogenic drivers for NSCLC (Konduri, K., et al. Cancer Discovery 2016, 6 (6), 601-611). The first-generation EGFR tyrosine kinase inhibitors (EGFR-TKIs) gefitinib and erlotinib have approved for NSCLC patients with EGFR activation mutations (M. Maemondo, N. Engl. J. Med. 362 (2010) 2380-2388). Although most patients with EGFR mutant NSCLC respond to these therapies, patients typically develop resistance after an average of one year on treatment. There are several mechanisms of acquired resistance to gefitinib and erlotinib, including a secondary threonine 790 to methionine 790 mutation (T790M), is also called “gatekeeper” T790M mutation (Xu Y., et al. Cancer Biol Ther. 2010, 9 (8): 572-582). Therefore, the second-generation EGFR-TKIs afatinib and the third-generation EGFR-TKIs osimertinib (AZD9291) were developed as irreversible EGFR inhibitors that bind to Cys797 for the treatment of patients with T790M mutation. In particular, osimertinib that largely spares WT EGFR has achieved greater clinical response rate in NSCLC patients with EGFR T790M. However, several recent studies have reported a tertiary Cys797 to Ser797 (C797S) point mutation with osimertinib clinical therapy (Thress K S, et al. Nat. Med. 2015, 21 (6): 560-562). There is a need for drugs which can overcome EGFR (C797S) resistance obstacle in non-small cell lung cancer (NSCLC). EGFR-Targeting PROTACs serve as a potential strategy to overcome drug resistance mediated by these mutants, which has been disclosed or discussed in patent publications, e.g. WO2018119441, WO2019149922, WO2019183523, WO2019121562 and US20190106417.
Although, a number of EGFR-targeting PROTACs which were designed to degrade EGFR mutant proteins have been published (Zhang X., et al. Eur. J. Med. Chem. 2020, 192, 112199; Zhang H, et al. Eur. J. Med. Chem. 2020, 189, 112061; Lu X, Med. Res. Rev. 2018, 38(5):1550-1581. He K., et al. Bioorg. Med. Chem. Lett. 2020, 15, 127167). Most of the published molecules are based on first, second, and third generation of EGFR inhibitors. However, there were no data which showed those EGFR-Targeting PROTACs degrading all the main EGFR mutations, Such as Del19, L858R, Del19/T790M, L858R/T790M, Del19/T790M/C797S, L858R/T790M/C797S.
The present application provides novel bifunctional compounds and compositions for the treatment of serious diseases.
One objective of the present invention is to provide compounds and derivatives formed by conjugating EGFR inhibitor moieties with E3 ligase Ligand moieties, which function to recruit targeted proteins to E3 ubiquitin ligase for degradation, and methods of preparation and uses thereof.

Compounds disclosed herein may contain an asymmetric center and may thus exist as enantiomers. “Enantiomers” refer to two stereoisomers of a compound which are non-superimposable mirror images of one another. Where the compounds disclosed herein possess two or more asymmetric centers, they may additionally exist as diastereomers. Enantiomers and diastereomers fall within the broader class of stereoisomers. All such possible stereoisomers as substantially pure resolved enantiomers, racemic mixtures thereof, as well as mixtures of diastereomers are intended to be included. All stereoisomers of the compounds disclosed herein and/or pharmaceutically acceptable salts thereof are intended to be included. Unless specifically mentioned otherwise, reference to one isomer applies to any of the possible isomers. Whenever the isomeric composition is unspecified, all possible isomers are included.
When compounds disclosed herein contain olefinic double bonds, unless specified otherwise, such double bonds are meant to include both E and Z geometric isomers.
When compounds disclosed herein contain a di-substituted cyclic ring system, substituents found on such ring system may adopt cis and trans formations. Cis formation means that both substituents are found on the upper side of the 2 substituent placements on the carbon, while trans would mean that they were on opposing sides. For example, the di-substituted cyclic ring system may be cyclohexyl or cyclobutyl ring.
It may be advantageous to separate reaction products from one another and/or from starting materials. The desired products of each step or series of steps is separated and/or purified (hereinafter separated) to the desired degree of homogeneity by the techniques common in the art. Typically such separations involve multiphase extraction, crystallization from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods including, for example: reverse-phase and normal phase; size exclusion; ion exchange; high, medium and low pressure liquid chromatography methods and apparatus; small scale analytical; simulated moving bed (“SMB”) and preparative thin or thick layer chromatography, as well as techniques of small scale thin layer and flash chromatography. One skilled in the art could select and apply the techniques most likely to achieve the desired separation.
“Diastereomers” refer to stereoisomers of a compound with two or more chiral centers but which are not mirror images of one another. Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereoisomers to the corresponding pure enantiomers. Enantiomers can also be separated by use of a chiral HPLC column.
A single stereoisomer, e.g., a substantially pure enantiomer, may be obtained by resolution of the racemic mixture using a method such as formation of 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 invention can be separated and isolated by any suitable method, including: (1) formation of ionic, diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure stereoisomers, and (3) separation of the substantially pure or enriched stereoisomers directly under chiral conditions. See: Wainer, Irving W., Ed. Drug Stereochemistry: Analytical Methods and Pharmacology. New York: Marcel Dekker, Inc., 1993.
Some of the compounds disclosed herein may exist with different points of attachment of hydrogen, referred to as tautomers. For example, compounds including carbonyl —CH2C(O)— groups (keto forms) may undergo tautomerism to form hydroxyl —CH═C(OH)— groups (enol forms). Both keto and enol forms, individually as well as mixtures thereof, are also intended to be included where applicable.
“Prodrug” refers to a derivative of an active agent that requires a transformation within the body to release the active agent. In some embodiments, the transformation is an enzymatic transformation. Prodrugs are frequently, although not necessarily, pharmacologically inactive until converted to the active agent.
“deuterated analog” refers to a derivative of an active agent that an arbitrary hydrogen is substituted with deuterium. In some embodiments, the deuterated site is on the Warhead moiety. In some embodiments, the deuterated site is on the Linker moiety. In some embodiments, the deuterated site is on the Degron moiety.
“Pharmaceutically acceptable salts” refer to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. A pharmaceutically acceptable salt may be prepared in situ during the final isolation and purification of the compounds disclosed herein, or separately by reacting the free base function with a suitable organic acid or by reacting the acidic group with a suitable base. The term also includes salts of the stereoisomers (such as enantiomers and/or diastereomers), tautomers and prodrugs of the compound of the invention.
In addition, if a compound disclosed herein is obtained as an acid addition salt, 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 pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methodologies that may be used without undue experimentation to prepare non-toxic pharmaceutically acceptable addition salts.
The terms “administration”, “administering”, “treating” and “treatment” herein, when applied to an animal, human, experimental subject, cell, tissue, organ, or biological fluid, mean contact of an exogenous pharmaceutical, therapeutic, diagnostic agent, or composition to the animal, human, subject, cell, tissue, organ, or biological fluid. Treatment of a cell encompasses contact of a reagent to the cell, as well as contact of a reagent to a fluid, where the fluid is in contact with the cell. The term “administration” and “treatment” also means in vitro and ex vivo treatments, e.g., of a cell, by a reagent, diagnostic, binding compound, or by another cell. The term “subject” herein includes any organism, preferably an animal, more preferably a mammal (e.g., rat, mouse, dog, cat, and rabbit) and most preferably a human.
The term “effective amount” or “therapeutically effective amount” refers to an amount of the active ingredient, such as compound that, when administered to a subject for treating a disease, or at least one of the clinical symptoms of a disease or disorder, is sufficient to affect such treatment for the disease, disorder, or symptom.
