MACROCYCLIC COMPOUNDS AS RAS INHIBITORSFIELD OF THE INVENTION
[0001] The present invention provides macrocyclic compounds, the use thereof for selectively inhibiting the activity of RAS mutants, and pharmaceutical compositions comprising the compounds as treatment of various diseases including cancer.BACKGROUND OF THE INVENTION
[0002] Rat sarcoma (RAS) gene mutations are driving factors in several fatal cancers. The three canonical RAS genes, kirsten-RAS (KRAS) , neuroblastoma-RAS (NRAS) , and harvey-RAS (HRAS) altogether are mutated in approximately 19%of cancer patients [Prior, I. A., Cancer Research, 2020, 80 (14) : pp. 2969-74] . RAS and its downstream pathways govern assorted biological activities, such as cell proliferation, survival, migration, etc. Consequently, RAS mutations genetically drive numerous types of cancers, encompassing non-small-cell lung cancer (NSCLC) , pancreatic ductal adenocarcinoma (PDAC) , colorectal cancer (CRC) , melanoma and some haematological cancers [Moore, A. R., Nature Reviews Drug Discovery, 2020, 19: pp. 533-52] .
[0003] In essence, RAS GTPases cycle between two switchable states, guanosine diphosphate (GDP) -bound inactive form (RAS OFF) and guanosine triphosphate (GTP) -bound active form (RAS ON) [Fey, D., et al. Semin Cell Dev Biol., 2016, 58, 96-107] . In the RAS ON status, RAS has a high affinity for many effectors which allow it to carry out its functions. Common mutations of RAS gene disrupt the intrinsic cycle and lock RAS in a permanently GTP-bound conformation, which in turn constitutively activate downstream pathways.
[0004] The daunting challenges of RAS-targeted therapy stem from the smooth globular protein structures and the picomolar binding strength between RAS and GTP, which conspire to make RAS hardly druggable [Yang, H., Cancer Communication, 2023, 43 (1) : pp. 42-74] . Aiming at this ‘undruggable’ target, pioneering work majorly employed the allele-specific strategy. For example, exploiting the nucleophilicity of cysteine in KRASG12C mutant, covalent small-molecule inhibitors have been extensively studied, which culminated in the approval of sotorasib and adagrasib by FDA.
[0005] Despite the great progress of these subtype-specific inhibitors, rapid acquired drug resistance might limit their further therapeutic potential. RAS pathway reactivation via different mechanisms (especially through compensation from NRAS and HRAS) could result in primary resistance to KRASG12C inhibition [Noritaka, T., Cancer Discovery, 2021, 11: pp. 1913-22] . Moreover, non-G12C mutations constitute a great portion of RAS alterations in different cancers. The unmet medical needs urge development of pan-RAS therapeutics.SUMMARY OF THE INVENTION

[0107] Compounds disclosed herein may contain an asymmetric center, axis, or plane 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.
[0108] The term “axial chirality” is used to refer to stereoisomerism resulting from the non-planar arrangement of four groups in pairs about a chirality axis.

For example, the di-substituted cyclic ring system may be cyclohexyl or cyclobutyl ring.
[0114] It may be advantageous to separate reaction products from one another and / or from starting materials. The desired product (s) 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.
[0115] “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.
[0116] 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.

Both keto and enol forms, individually as well as mixtures thereof, are also intended to be included where applicable.
[0118] “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.
[0119] "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.
[0120] 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.

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.
[0122] 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 effect such treatment for the disease, disorder, or symptom. The term “therapeutically effective amount” can vary with the compound, the disease, disorder, and / or symptoms of the disease or disorder, severity of the disease, disorder, and / or symptoms of the disease or disorder, the age of the subject to be treated, and / or the weight of the subject to be treated. An appropriate amount in any given instance can be apparent to those skilled in the art or can be determined by routine experiments. In some embodiments, “therapeutically effective amount” is an amount of at least one compound and / or at least one stereoisomer, tautomer or prodrug thereof, and / or at least one pharmaceutically acceptable salt thereof disclosed herein effective to “treat” as defined herein, a disease or disorder in a subject. In the case of combination therapy, the term “therapeutically effective amount” refers to the total amount of the combination objects for the effective treatment of a disease, a disorder or a condition.
[0123] The term “disease” refers to any disease, discomfort, illness, symptoms or indications, and can be interchangeable with the term “disorder” or “condition” .
[0124] Throughout this specification and the claims which follow, unless the context requires otherwise, the term "comprise" , and variations such as "comprises" and "comprising" are intended to specify the presence of the features thereafter, but do not exclude the presence or addition of one or more other features. When used herein the term "comprising" can be substituted with the term "containing" , "including" or sometimes "having" .
[0125] Throughout this specification and the claims which follow, the term “Cn-m” indicates a range which includes the endpoints, wherein n and m are integers and indicate the number of carbons. Examples include C1-8, C1-6, and the like.
[0126] Illustrations herein showing a substituent (s) bonded to a cyclic group (e.g., aryl, heteroaryl, cycloalkyl, fused cyclic group, spiro cyclic group) through a bond between ring atoms are meant to indicate, unless specified otherwise, that the substituent (s) may be bonded to the cyclic group at any ring position of the ring through which the substituent bond passes, so long as such substitution results in a stable compound. Thus, for example, substituent R2 in Formula (I) herein is the substituent of moiety, and not the aromatic rings to which such moiety is fused in Formula (I) . Thus, for example, substituent R2 in Formula (I) may be bonded to the carbon (s) of moiety enclosed in brackets, or the carbon of X when X is CH2.
[0127] Unless specifically defined elsewhere in this document, all other technical and scientific terms used herein have the meaning commonly understood by one of ordinary skill in the art to which this invention belongs. EXAMPLES General Synthesis

[0353] Method 1: pERK inhibition in AsPC-1 (KRAS G12D) cells. AsPC-1 cell line (pancreatic cancer cell line harboring KRAS G12D mutation) was used in this study. Cells were maintained in RPMI 1640 supplemented with 10%fetal bovine serum (Thermo Fisher) , 50 units / mL penicillin and streptomycin (Thermo Fisher) and kept at 37 ℃ in a humidified atmosphere of 5%CO2 in the air. Cells were reinstated from frozen stocks that were laid down within 30 passages from the original cells purchased. 30,000 cells per well were seeded into a 96-well plate and incubated overnight. Cells were treated with a 10-point dilution series of test compounds, with final compound concentration of from 0 to 10 μM. After 2 h compound treatment, cells were lysed, and the pERK1 / 2 (THR202 / TYR204) level in the cell lysates was detected by HTRF kit (Cisbio) with protocol vide infra. In brief, a total of 16 μL of cell lysate from each well of a 96-well plate was transferred to a 384-well white assay plate. Lysate from each well was incubated with 2 μL of Eu3+ -cryptate (donor) labeled anti-pERK1 / 2 and 2 μL of D2 (acceptor) labeled anti-pERK1 / 2 antibodies (Cisbio) overnight in dark at room temperature. When donor and acceptor are in proximity, excitation of the donor with laser triggers fluorescence resonance energy transfer towards the acceptor, which in turn fluoresces at 655 nm wavelength. FRET signals were measured using a PHERAstar FSX reader (BMG Labtech) . IC50 determination was performed by fitting the curve of percent inhibition versus the log of the compounds disclosed herein concentration using Dotmatics. The results are reported in Table 2.
