Description

[Technical Field]

[0001] This invention relates to novel triazine compounds containing chemically reactive groups (warheads) that serve as therapeutic agents and chemical probes useful for regulating cellular activities such as signal transduction, proliferation, differentiation, and cell death. The compounds of this invention regulate kinase activity, particularly the activity of phosphoinositide 3-kinase (PI3K). [Background technology]

[0002] Protein kinases are involved in signaling events and regulate cell activation, growth, differentiation, survival, and migration in response to extracellular mediators or stimuli (including growth factors, cytokines, or chemokines).

[0003] Increased protein kinase activity is associated with many diseases, including cancer, inflammatory disorders, and metabolic and immune disorders. These can be caused directly or indirectly by dysfunction of regulatory mechanisms due to mutations, overexpression, or improper control of enzyme activity.

[0004] The phosphoinositide 3-kinase (PI3K) signaling pathway plays a crucial role in many cellular processes, including cell growth, proliferation, and survival. The PI3K family is divided into three classes according to their amino acid sequence, homology, and substrate specificity. Class I PI3Ks are activated downstream of cell surface receptors, including receptor protein tyrosine kinases (RTKs), G protein-coupled receptors (GPCRs), and immunoglobulin receptors. Class IA PI3Ks are obligate heterodimers consisting of a catalytic subunit (p110α, p110β, or p110δ) and associated regulatory subunits (p85α, p85β, p50α, p55α, or p55γ). Class IB PI3Kγ acts downstream of GPCRs and consists of a catalytic subunit (p110γ) and an adapter subunit (p84 or p101). The cell surface receptor activates PI3K, producing PtdIn(3,4,5)P3, which acts as a docking site for protein kinase B (PKB / Akt) and 3-phosphoinositide-dependent protein kinase 1 (PDK1). This leads to phosphorylation of the kinase domain at two regulatory sites: Thr308 by PDK1 and Ser473 by mTOR complex 2 (mTORC2). Overactivation of the PI3K / mTOR pathway can occur at multiple levels of this signaling cascade, ultimately promoting cancer growth and progression. Loss or inactivation of tumor suppressor phosphatases and tensin homologs (PTENs), mutations or amplification of cell surface receptors, and the presence of activating hotspot mutations in PIK3CA play important roles in human carcinogenesis. Furthermore, overactivation of the PI3K / mTOR axis is associated with resistance to multiple cancer treatments. Therefore, PI3K inhibitors are considered to have high value in cancer treatment.

[0005] Considerable efforts have been devoted to the development of drugs targeting PI3K signaling, and many of them are currently being evaluated in clinical trials. Selective PI3Kα inhibitors may be beneficial for PIK3CA mutant tumors and PIK3CA-related overgrowth syndrome (PROS), and can minimize the on-target metabolic side effects of pan-PI3K inhibitors. BYL719 / Alpelisib / PIKRAY from Novartis and GDC-0032 / Taselisib from Genentech act as reversible modifiers and are claimed as PI3Kα-selective inhibitors. However, at the concentrations required for in vivo experiments, they cannot distinguish PI3K isoforms. Only one PI3Kα covalent inhibitor called CNX-1351 is currently available, but it exhibits limited in vitro and cellular potency, low water solubility, and metabolic instability.

[0006] This patent application describes certain triazine derivatives having PI3K inhibitory activity and acting as irreversible and reversible covalent modifiers, as well as their use as pharmaceuticals. The compounds covered herein have significant advantages with respect to potency, metabolic stability, and drug-like properties compared to CNX-1351. Furthermore, this patent application describes linkers for the development of covalent kinase inhibitors.

[0012] Detailed description of the invention Herein, certain embodiments of the present invention are described in detail, and examples thereof are illustrated in the attached structures and formulas. The present invention is described in conjunction with the listed embodiments, but it will be understood that they are not intended to limit the present invention to those embodiments. Rather, the present invention is intended to cover all substitutes, modifications, and equivalents that may fall within the scope of the present invention as defined by the claims. Those skilled in the art will recognize many methods and materials similar or equivalent to those described herein that can be used in the practice of the present invention. The present invention is by no means limited to the methods and materials described herein.

[0013] definition As used herein, the term "alkyl" refers to a saturated linear monovalent hydrocarbon group having 1 to 5 carbon atoms (C1 to C5). Examples of alkyl groups include, but are not limited to, methyl, ethyl, 1-propyl (n-propyl), and 1-butyl (n-butyl).

[0014] The terms “heterocyclic,” “heterocyclyl,” and “heterocyclic ring” are used interchangeably herein and refer to a saturated or unsaturated carbocyclic radical of 4 to 6 ring atoms, in which at least one ring atom is a heteroatom, in particular nitrogen, the remaining ring atoms are carbon atoms, and one or more ring atoms are optionally independently substituted with one or more substituents selected in particular from -CH3 and -F.

[0015] The term "chiral" refers to a molecule that cannot be superimposed on its mirror image partner, while the term "achiral" refers to a molecule that can be superimposed on its mirror image partner.

[0016] The term "stereoisomer" refers to compounds that have the same chemical structure but differ in the arrangement of atoms or groups in space.

[0017] A "diastereomer" refers to a stereoisomer of a compound that has two or more chirality centers that are not mirror images of each other. Diastereomers have different physical properties, such as melting point, boiling point, spectral properties, and chemical and biological reactivity. Mixtures of diastereomers can be separated under high-resolution analytical procedures such as electrophoresis and chromatography.

[0018] An "enantiomer" refers to two stereoisomers of a compound that are mirror images of each other and cannot be superimposed.

[0019] The definitions and conventions of stereochemistry used herein generally follow the McRaw-Hiff Dictionary of Chemical Terms (1984) edited by SP. Parker, McGraw-Hill Book Company, New York; and "Stereochemistry of Organic Compounds" by Eliel, E. and Wilen, S., John Wiley & Sons, Inc., New York, 1994. The compounds of the present invention may contain a chiral or asymmetric center and therefore may exist in various stereoisomeric forms. All stereoisomeric forms of the compounds of the present invention, including but not limited to diastereomers, enantiomers, and atropisomers, and mixtures thereof, such as racemic mixtures, are intended to form part of the present invention. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of polarization. When describing optically active compounds, the prefixes R and S are used to indicate the absolute configuration of the molecule around its chiral center. For a given chemical structure, these stereoisomers are identical except that they are mirror images of each other. Certain stereoisomers are sometimes called enantiomers, and mixtures of such isomers are often called enantiomer mixtures. A 50:50 mixture of enantiomers is called a racemic mixture or racemate. The term "tautomer" or "tautomeristic form" refers to structural isomers of different energies that can be interconverted across a low-energy barrier. For example, proton tautomers include interconversions by proton transfer, such as keto-enol isomerization and imine-enamine isomerization.

[0020] The term "enone" refers to an α,β-unsaturated carbonyl, a type of organic compound consisting of an alkene conjugated to a ketone. The simplest enones are methyl vinyl ketone (butenone) or CH2=CHCOCH3. These are electrophilic at both the carbonyl and β-carbons. Depending on the conditions, either site is attacked by a nucleophile. Addition to an alkene is called Michael addition and is used in this invention to covalently modify cysteine ​​862 in PI3Kα.

[0021] The term "acrylamide" is derived from acrylic acid and refers to an amide having the general chemical formula CH2=CHC(O)NH2. Acrylamide is used in the compounds of the present invention and undergoes Michael addition with cysteine ​​862 in PI3Kα.

[0022] The term "PI3K" refers to phosphoinositide 3-kinase.

[0023] The terms "PI3K alpha," "PI3Kα," or "p110a protein" refer to the subunit of PI3K encoded by the PI3KCA gene.

[0024] The terms “irreversible” or “irreversible inhibitor” refer to inhibitors that can covalently bind to PI3 kinase substantially irreversibly, whereas reversible inhibitors can bind to the kinase (but generally cannot form a covalent bond) and are therefore able to dissociate from PI3 kinase. Once covalent bond formation occurs, an irreversible inhibitor remains substantially bound to the kinase. Methods for determining whether a compound is acting as an irreversible inhibitor are known to those skilled in the art. Such methods include, but are not limited to, enzymatic kinetic analysis of the inhibitory profile of a compound by the kinase, the use of mass spectrometry of a protein-drug target modified in the presence of an inhibitor compound, the use of X-ray crystallography to analyze the complex between the protein-drug target and the inhibitor compound, intermittent exposure also known as a “washout” experiment, and other methods known to those skilled in the art.

[0025] The term "reversible covalent bonding" refers to inhibitors that covalently modify target cysteine, but the free energy difference separating non-covalent reactants from the bonded product is close to equilibrium, the activation barrier is relatively low, and as a result, the reverse reaction that cleaves the chemical bond occurs easily (examples include nitrile-based reversible covalent inhibitors).

[0026] The terms "warhead" or "warhead group" refer to a functional group present in the compound of the present invention that covalently binds to an amino acid residue (e.g., cysteine, lysine, histidine, or other residues that can be covalently modified) present in the binding pocket of a target protein, thereby irreversibly inhibiting the protein. The warhead group is essential for covalent and irreversible inhibition of the protein.

[0027] The term "inhibitor" is defined as a compound that binds to and inhibits PI3 kinase with measurable affinity. In certain embodiments, the inhibitor is IC 50 and / or rate constant (k) for irreversible deactivation inact Characterized by:

[0028] The term "CNX-1351" refers to 1-[4-[[2-(1H-indazole-4-yl)-4-(4-morpholinyl)thieno[3,2-d]pyrimidine-6-yl]methyl]-1-piperazinyl]-6-methyl-5-hepten-1,4-dione (CAS 1276105-89-5).

[0029] When used herein, the expression "pharmaceutically acceptable salt" refers to a pharmaceutically acceptable organic or inorganic salt of the compound of the present invention. If the compound of the present invention is a base, a desired pharmaceutically acceptable salt can be prepared by any suitable method available in the art, for example, by treating a free base with an inorganic acid such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, methanesulfonic acid, or phosphoric acid, or with an organic acid such as pyranosidylic acid such as acetic acid, trifluoroacetic acid, maleic acid, succinic acid, mandelic acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, glucuronic acid, or galacturonic acid, alpha hydroxy acids such as citric acid or tartaric acid, amino acids such as aspartic acid or glutamic acid, aromatic acids such as benzoic acid or cinnamic acid, or sulfonic acids such as p-toluenesulfonic acid or ethanesulfonic acid.

[0030] The term "protecting group" refers to a substituent commonly used to block or protect a specific functional group during the reaction of other functional groups on a compound. For example, an "amino protecting group" is a substituent attached to an amino group that blocks or protects an amino functional group in a compound. Suitable amino protecting groups include acetyl, trifluoroacetyl, tert-butoxycarbonyl (BOC), benzyloxycarbonyl, and 9-fluorenylmethyleneoxycarbonyl (Fmoc). For a general explanation of protecting groups and their uses, see Protective Groups in Organic Synthesis by TW Greene, John Wiley & Sons, New York, 1991.

[0031] The terms “compounds of the present invention” and “compounds of formula (I, II, III)” include their stereoisomers, geometric isomers, tautomers, solvates, pharmaceutically acceptable salts, and solvates of those salts.

[0032] Detailed explanation The present invention relates to novel triazine-based compounds that act as reversible or irreversible modifiers of PI3 kinase, particularly PI3Kα, and their use as therapeutic agents and chemical probes.

[0033] The compounds of the present invention have higher water solubility (>30-fold), higher potency in vitro and intracellularly (>7-fold), and higher metabolic stability compared to the known inhibitor CNX-1351.

[0034] An important aspect of the present invention relates to the favorable reaction parameters in preferred molecules (particularly inhibitors characterized by a warhead that forms an acrylamide moiety) that result in highly selective target binding and reduced or negligible off-target reactivity, i) The on-target reaction of a covalent inhibitor is described by the inhibitor dissociation constant K that accounts for the reversible equilibrium of complex formation between the enzyme (E) and the inhibitor (I) i E + I ←→ E~I and the reaction rate k that defines the formation of a covalent inhibitor-enzyme complex (EI) between the inhibitor and the enzyme inact as defined by E~I → EI ii) The off-target reaction with ubiquitous sulfhydryls (S) and other nucleophiles present in physiological environments such as cells and body fluids is driven by the intrinsic reactivity of the warhead defined by k chem and results in the formation of sulfhydryl adducts (SI) by driving the conversion of S and I S + I → SI

[0035] A high intrinsic warhead reactivity (high k chem value) leads to the formation of undesirable sulfhydryl adducts that result in compound loss, covalent modification of cellular components, toxicity, and anti-compound immune responses:
