TRICYCLIC COMPOUNDS AND USES THEREOFTechnical Field
[0001] The present invention relates to tricyclic compounds, pharmaceutical compositions comprising same, preparation methods therefor and uses thereof.Background Art
[0002] RAS (rat sarcoma virus) proteins are a type of membrane-bound guanosine triphosphate hydrolase (aGTP hydrolase) , and currently, there are three known genes in the RAS family: KRAS, NRAS and HRAS. The RAS protein functions as a molecular switch, which is activated and in an “ON” state when binding to GTP and is inactivated and in an “OFF” state when GTP is hydrolyzed. This process is regulated by a guanine nucleotide exchange factor (GEF) or a GTPase-activating protein (GAP) : the GEF stimulates the exchange of guanosine diphosphate (GDP) with guanosine triphosphate (GTP) , whereas the GAP promotes the hydrolysis of the GTP. Research has shown that the RAS genes have a high frequency of missense mutations in tumors, with three mutational hotspots at G12, G13, and Q61, respectively. These mutations can enable the binding of the RAS protein to GTP for a long time, resulting the continuous activation of the downstream effector signals, and driving the formation and development of tumors. KRAS is one of the important members of the RAS family, with the main downstream signaling pathways including PI3K / AKT, RAF / MEK / ERK, etc., which regulate various biological functions such as cell proliferation, apoptosis, and differentiation.
[0003] The abnormal activation of RAS proteins is closely related to tumorigenesis, among which KRAS mutations are the most common, accounting for about 85%, NRAS and HRAS accounting for 12%and 3%, respectively. The KRAS mutations are predominant in pancreatic cancer, colorectal cancer and lung cancer, the NRAS mutations are more common in melanoma and acute myeloid leukemia, and the HRAS mutations are more common in bladder cancer and head and neck cancer. The KRAS mutations are most common with G12 mutation at codon 12, G12C is the most common KRAS mutation in NSCLC patients, and KRAS G12D and KRAS G12V are the most common mutations in colorectal cancer and pancreatic cancer. Amplification of the KRAS gene has also been found in a variety of tumors, with an incidence of approximately 15%in esophageal adenocarcinoma and chromosomal instability gastric cancer.
[0004] Although the close relationship between KRAS and tumors has attracted much attention to this target, it took scientists more than thirty years of study to turn it into a targetable protein. In May 2021, the KRAS G12C inhibitor of Lumakras from the Amgen received accelerated approval from the US FDA, marking a significant breakthrough in breaking the “undruggability” of KRAS. However, the KRAS G12C patient population only accounts for a small portion of the KRAS mutation patients, and a large number of patients require medicaments targeting other KRAS mutations. Currently, no medicament against mutations other than the KRAS G12C mutation has been approved globally. Therefore, the development of KRAS targeted medicaments, in particular pan-KRAS targeted drugs, has broad application prospects.Summary of the Invention

[0061] The term “-OH” as used herein refers to hydroxyl radical.
[0062] The term “-CN” as used herein refers to cyano radical.
[0063] The term “oxo” as used herein refers to=O.
[0064] The term “optional” or “optionally” as used herein means that the subsequently described event or circumstance may or may not occur, and the description includes instances wherein the event or circumstance occur and instances in which it does not occur. For example, “optionally substituted with one or more” includes unsubstituted and substituted with one or more substituents as described. It will be understood by those skilled in the art, with respect to any group containing one or more substituents, that such groups are not intended to introduce any substitution or substitution patterns that are sterically impractical, chemically incorrect, synthetically non-feasible and / or inherently unstable.
[0065] The term “substituted” or “substituted with... ” , as used herein, means that one or more (such as, 1, 2, 3 or 4) hydrogens on the designated atom or group are replaced with one or more (such as 1, 2, 3 or 4) substituents, preferably the substituents selected from the indicated group of substituents or radicals, provided that the designated atom’s normal valence is not exceeded. The said substituents may be the same or different from each other. The term “substituted with one or more groups selected from... ” or “substituted with one or more... ” as used herein means that one or more hydrogens on the designated atom or group are independently replaced with one or more radicals from the indicated group of substituents or radicals, wherein the said radicals may be the same or different from each other. Preferably, “substituted with one or more groups selected from... ” or “substituted with one or more... ” means that the designated atom or group is substituted with 1, 2, 3, or 4 radicals independently selected from the indicated group of substituents or radicals, wherein the said radicals may be the same or different from each other. In some embodiments, when a substituent is oxo (i.e., =O) , then 2 hydrogens on a single atom are replaced by the oxo. An optional substituent can be any radicals, provided that combinations of substituents and / or variables result in a chemically correct and stable compound. A chemically correct and stable compound is meant to imply a compound that is sufficiently robust to survive sufficient isolation from a reaction mixture to be able to identify the chemical structure of the compound. Preferably, substituents are those exemplified in the compounds of the examples of the present application.
[0066] Unless otherwise specified, substituents are named into the core structure. For example, it is to be understood that when (cycloalkyl) alkyl is listed as a possible substituent, the point of attachment of this substituent to the core structure is in the alkyl portion.
[0067] When a structural formula herein contains an asterisk “*” , it means that the chiral center at the “*” mark in the compound is a single configuration of (R) configuration or (S) configuration; wherein the content of the single-configuration compound marked with **” is at least 90% (e.g., 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 100%, or any value between these listed values) . For example, some compounds of the present invention, such as the following compound of formula (a) , and its structural formula contains an asterisk “*” , which means that the compound is a compound of formula (b) or compound of formula (c) in a single configuration.
[0068] It will be appreciated by the person of ordinary skill in the art ( “POSITA” ) that some of the compounds of formula (I) may contain one or more chiral centers and therefore exist in two or more stereoisomeric forms. The racemates of these isomers, the individual isomers and mixtures enriched in one enantiomer, as well as diastereomers when there are two chiral centers, and mixtures partially enriched with specific diastereomers are within the scope of the present invention. It will be further appreciated by the POSITA that the present invention includes all the individual stereoisomers (e.g. enantiomers, diastereomers) , racemic mixtures or partially resolved mixtures of the compounds of formula (I) and, where appropriate, the individual tautomeric forms thereof.
[0069] The term “stereoisomers” as used herein refers to compounds that have the same chemical constitution but differ in the arrangement of atoms or groups in space. Stereoisomers include enantiomers, diastereomers and the like.
[0070] The terms “enantiomers” and “enantiomeric forms” as used herein can be used interchangeably and refer to two stereoisomers of a compound that are non-superimposable mirror images of each other.
[0071] The terms “diastereomers” and “diastereomeric forms” as used herein can be used interchangeably and refer to stereoisomers that have two or more chiral centers and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting points, boiling points, spectral properties, or biological activities. A mixture of diastereomers can be separated by high-resolution analytical methods such as electrophoresis and chromatography such as HPLC.
[0072] In some embodiments, the present invention provides compounds of various stereoisomeric purities, that is, enantiomeric or diastereomeric purity expressed in different “ee” or “de” values. In some embodiments, the compound of formula (I) described herein has an enantiomeric purity of at least 60%ee (e.g., 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 100%ee, or any value between these listed values) . In some embodiments, the compound of formula (I) described herein has an enantiomeric purity of greater than 99.9%ee. In some embodiments, the compound of formula (I) described herein has a diastereomeric purity of at least 60%de (e.g., 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 100%de, or any value between these listed values) . In some embodiments, the compound of formula (I) described herein has a diastereomeric purity of greater than 99.9%de.
[0073] The term “enantiomeric excess” or “ee” refers to the amount of one enantiomer relative to the other. For a mixture of R and S enantiomers, the percentage of enantiomeric excess is defined as |R-S|*100, where R and S are the mole or weight fractions of the respective enantiomers in the mixture, R + S = 1. If the optical rotation of a chiral substance is known, the percentage of enantiomeric excess is defined as ( [a] obs / [a] max) *100, wherein [a] obs is the optical rotation of the enantiomeric mixture, and [a] max is the optical rotation of the pure enantiomer.
[0074] The term “diastereomeric excess” or “de” refers to the amount of one diastereomer relative to the other, and is defined by analogy based on the enantiomeric excess. Therefore, for a mixture of diastereomers D1 and D2, the percentage of diastereomeric excess is defined as |D1-D2|*100, wherein D1 and D2 are the mole or weight fractions of the respective diastereomers in the mixture, D1 + D2 = 1.
[0075] The diastereomeric excess and enantiomeric excess can be measured by a number of analytical techniques (including nuclear magnetic resonance spectroscopy, chiral column chromatography and / or optical polarimetry) according to conventional protocols well known to a person skilled in the art.
[0076] The racemates can be used as such or can be resolved into their individual isomers. The resolution can afford stereochemically pure compounds or mixtures enriched in one or more isomers. Methods for separation of isomers are well known (cf. Allinger N.L. and Eliel E.L. in “Topics in Stereochemistry” , Vol. 6, Wiley Interscience, 1971) and include physical methods such as chromatography using a chiral adsorbent. Individual isomers can be prepared in chiral form from chiral precursors. Alternatively, individual isomers can be separated chemically from a mixture by: forming diastereomeric salts with a chiral acid (such as the individual enantiomers of 10-camphorsulfonic acid, camphoric acid, alpha-bromocamphoric acid, tartaric acid, diacetyltartaric acid, malic acid, pyrrolidone-5-carboxylic acid, and the like) , fractionally crystallizing the salts, and then freeing one or both of the resolved bases, optionally repeating the process, so as obtain either or both substantially free of the other; i.e., in a form having an optical purity of > 95%. Alternatively, the racemates can be covalently linked to a chiral compound (auxiliary) to produce diastereomers which can be separated by chromatography or by fractional crystallization after which time the chiral auxiliary is chemically removed to afford the pure enantiomers.
[0077] The term “tautomer” as used herein refers to constitutional isomers of compounds generated by rapid movement of an atom in two positions in a molecule. Tautomers readily interconvert into each other, e.g., enol form and ketone form are tipical tautomers.
[0078] A “pharmaceutically acceptable salt” is intended to mean a salt of a free acid or base of a compound of Formula (I) that is non-toxic, biologically tolerable, or otherwise biologically suitable for administration to the subject to be treated or prevented. For example, an acid addition salt includes such as a salt derived from an inorganic acid and an organic acid. For examples, see, generally, S.M. Berge, et al., “Pharmaceutical Salts” , J. Pharm. Sci., 1977, 66: 1-19, and Handbook of Pharmaceutical Salts, Properties, Selection, and Use, Stahl and Wermuth, Eds., Wiley-VCH and VHCA, Zurich, 2002.
[0079] In addition, if a compound described herein is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid addition salt. Conversely, if the product is a free base, an acid addition salt, particularly a pharmaceutically acceptable acid addition salt, may be produced by dissolving the free base in a suitable solvent and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds. The POSITA will recognize various synthetic methodologies that may be used without undue experimentation to prepare non-toxic pharmaceutically acceptable acid addition salts or base addition salts.
[0080] The term “solvate” means solvent addition forms that contain either stoichiometric or non-stoichiometric amounts of solvent. Some compounds have a tendency to trap a fixed molar ratio of solvent molecules in the solid state, thus forming a solvate. If the solvent is water, the solvate formed is a hydrate, when the solvent is alcohol, the solvate formed is an alcoholate. Hydrates are formed by the combination of one or more molecules of water, or less than one molecule of water, with one molecule of the substances in which the water retains its molecular state as H2O, such combination being able to form one or more hydrates, for example, hemihydrate, monohydrate, and dihydrate.
[0081] The compounds of the present invention also embrace isotopically-labeled compounds that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. All isotopes of any particular atom or element as specified are contemplated herein, and their uses. Exemplary isotopes that can be incorporated into compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine and iodine, such as 2H, 3H, 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 32P, 33P, 35S, 18F, 36Cl, 123I, and 125I. Certain isotopicaliy-labeled compounds of the present invention (e.g., those labeled with 3H and 14C) are useful in compound and / or substrate tissue distribution assays. Tritium (i.e., 3H) and carbon-14 (i.e., 14C) isotopes are particularly useful for this purpose in view of their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., 2H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. It will be appreciated that the hydrogen (1H) atom present in the compound of formula (I) described herein can be replaced with a deuterium (2H) atom to give the deuterated compound. In any given compound of formula (I) , any number of hydrogen atoms may be replaced by the same number of deuterium atoms. Isotopically labeled compounds of formula (I) can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the examples as set out below using an appropriate isotopicaily-labeled reagent in place of the non-labeled reagent.
[0082] As used herein, the terms “group (s) ” and “radical (s) ” are synonymous and are intended to indicate functional groups or fragments of molecules attachable to other fragments of molecules.
[0083] The term “active ingredient” is used to indicate a chemical substance which has biological activity. In some embodiments, an “active ingredient” is a chemical substance having pharmaceutical utility.
[0084] The term “pharmaceutical combination” as used herein means a product obtained by mixing or combining two or more active ingredients, including fixed and non-fixed combinations of active ingredients, such as a kit, and a pharmaceutical composition. The term “fixed combination” means that two or more active ingredients (such as compounds of the present invention and additional therapeutic agents) are administered simultaneously to a patient in the form of a single entity or dose. The term “non-fixed combination” means that two or more active ingredients (such as compounds of the present invention and additional therapeutic agents) are administered simultaneously, in parallel or successively to a patient in separate entities, wherein the administration provides the patient with a therapeutically effective level of the compound.
[0085] The terms “treating” or “treatment” or “prevention” of a disease or disorder, in the context of achieving therapeutic benefit, refer to administering one or more pharmaceutical substances, especially compounds of the present invention to a subject that has the disease or disorder, or has a symptom of a disease or disorder, or has a predisposition toward a disease or disorder, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affect the disease or disorder, the symptoms of the disease or disorder, or the predisposition toward the disease or disorder. In some embodiments, the disease or disorder is cancer, such as solid tumors or hematologic malignancies.
[0086] The terms “treating” , “contacting” and “reacting, ” in the context of a chemical reaction, mean adding or mixing two or more reagents under appropriate conditions to produce the indicated and / or the desired product. It should be appreciated that the reaction which produces the indicated and / or the desired product may not necessarily result directly from the combination of two reagents which were initially added, i.e., there may be one or more intermediates which are produced in the mixture which ultimately lead to the formation of the indicated and / or the desired product.
[0087] The term “effective amount” as used herein refers to an amount or dose of a KRAS inhibitor sufficient to generally bring about a therapeutic benefit in patients in need of treatment or prevention for a disease or disorder containing KRAS mutations or KRAS gene amplification. Effective amounts or doses of the active ingredient of the present disclosure may be ascertained by methods such as modeling, dose escalation studies or clinical trials, and by taking into consideration factors, e.g., the mode or route of administration or drug delivery, the pharmacokinetics of the agent, the severity and course of the disease or disorder, the subject’s previous or ongoing therapy, the subject’s health status and response to drugs, and the judgment of the attending physician.
[0088] An exemplary dose is in the range of from about 0.0001 to about 200 mg of active agent per kg of subject’s body weight per day, such as from about 0.001 to 100 mg / kg / day, or about 0.01 to 35 mg / kg / day, or about 0.1 to 10 mg / kg daily in single or divided dosage units (e.g., BID, TID, QID) . For a 70-kg human, an illustrative range for a suitable dosage amount is from about 0.05 to about 7 g / day, or about 0.2 to about 5 g / day. Once improvement of the patient’s disease or disorder has occurred, the dose may be adjusted for maintenance treatment. For example, the dosage or the frequency of administration, or both, may be reduced as a function of the symptoms, to a level at which the desired therapeutic effect is maintained. Of course, if symptoms have been alleviated to an appropriate level, treatment may cease. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.
[0089] The term “inhibition” or “inhibiting” indicates a decrease in the baseline activity of a biological activity or process. The term “inhibition of the activity of mutant KRAS proteins” is a practical pharmaceutical activity for purposes of this disclosure and refers to a decrease in the activity of mutant KRAS proteins as a direct or indirect response to the presence of the compound of the present invention, relative to the activity of mutant KRAS proteins in the absence of the compound of the present invention. The decrease in activity may be due to the direct interaction of the compound of the present invention with mutant KRAS proteins, or due to the interaction of the compound of the present invention, with one or more other factors that in turn affect the activity of mutant KRAS proteins. For example, the presence of the compound of the present invention may decrease the activity of mutant KRAS proteins by directly binding to the mutant KRAS proteins, by causing (directly or indirectly) another factor to decrease the activity of mutant KRAS proteins, or by (directly or indirectly) decreasing the amount of mutant KRAS proteins present in the cell or organism.
[0090] The term “subject” or “patient” as used herein means mammals and non-mammals. Mammals means any member of the mammalia class including, but not limited to, humans; non-human primates such as chimpanzees and other apes and monkey species; farm animals such as cattle, horses, sheep, goats, and swine; domestic animals such as rabbits, dogs, and cats; laboratory animals including rodents, such as rats, mice, and guinea pigs; and the like. Examples of non-mammals include, but are not limited to, birds, and the like. The term “subject” or “patient” does not denote a particular age or sex. In some embodiments, the subject or patient is a human.
[0091] In general, the term “about” is used herein to modify a numerical value above or below the stated value by a variance of 20%.
[0092] Technical and scientific terms used herein and not specifically defined have the meaning commonly understood by the POSITA to which the present disclosure pertains.
[0093] All numerical ranges herein shall be interpreted as disclosing each numerical value and subset of numerical values within the range, regardless of whether they are specifically otherwise disclosed. For example, when referring to any range of values, it should be regarded as referring to every value within the range of values, for example, every integer within the range of values. For example, C1-6 as used herein represents the inclusion of 1, 2, 3, 4, 5 or 6 C. The invention relates to all values falling within the ranges, all smaller ranges and the upper or lower limits of the numerical range.

[0211] Beneficial effects of the invention
[0212] As mentioned above, it is known that the abnormal activation of RAS proteins is closely related to tumorigenesis, among which KRAS mutations are the most common, and KRAS gene amplification has also been found in a variety of tumors. Inhibiting KRAS mutations or KRAS gene amplification can significantly inhibit cell proliferation in KRAS related diseases, such as cancer. We have surprisingly found that the compounds of the present invention can significantly inhibit KRAS mutations or KRAS gene amplification.
[0213] In some embodiments, the compounds of the present invention can inhibit the activity of KRAS in cells, especially the activity of mutant KRAS, for example the activity of one or more mutant KRAS, including but not limited to the activity of KRAS G12C, KRAS G12D, KRAS G12V, KRAS G13D, and / or KRAS Q61H.
[0214] In some embodiments, the compounds of the present invention can inhibit cell proliferation in cell lines containing KRAS mutations. For example, the compounds have a cell proliferation inhibitory activity in one or more cell lines containing KRAS mutations, including but not limited to KRAS G12C, KRAS G12D, KRAS G12V, KRAS G13D and / or KRAS Q61H mutations.
[0215] In some embodiments, the compounds of the present invention can inhibit cell proliferation in cell lines containing KRAS gene amplification. For example, the compounds have a cell proliferation inhibitory activity in cell lines containing wild-type KRAS gene amplification.
[0216] The compounds of the present invention have the aforementioned KRAS inhibitory activity and cell proliferation inhibitory activity, thereby having a potential value as anti-proliferative and / or pro-apoptotic medicaments in the prevention and / or treatment of diseases containing KRAS mutations or KRAS gene amplification, such as cancer or tumor as defined herein.
