Description

A type of PIKfyve protein kinase degrader and its use Technical Field

[0001] The present invention relates to the field of medicinal chemistry, and in particular to a class of compounds targeting ubiquitination degradation of PIKfyve protein, as well as pharmaceutical compositions and applications thereof. Background Art

[0002] PIKfyve is a lipid kinase that catalyzes the phosphorylation of phosphatidylinositol-3-phosphate (PI(3)P) to generate phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2). PI(4,5)P2 plays a key role in the formation of endosomes and lysosomes. PIKfyve is one of the key enzymes in cell membrane homeostasis, intracellular trafficking, and the autophagy pathway. Studies have shown that inhibiting or silencing PIKfyve in a variety of tumor cells can effectively inhibit their autophagy pathway, leading to significant accumulation of the key autophagy protein LC3, causing cells to produce obvious vacuolar morphology, and thus inhibiting their proliferation. Currently, multiple PIKfyve inhibitors are widely used in the research of tumor treatment for leukemia, prostate cancer, lymphoma, and other tumors.

[0003] In addition, PIKfyve plays an important role in the Toll-like receptor signaling pathway and is involved in the regulation of cellular innate immunity. Studies have shown that inhibiting PIKfyve can effectively suppress the production of IL-12 and IL-23 by immune cells such as B cells and macrophages. The PIKfyve inhibitor Apilimod has demonstrated specific inhibition of IL-12 and IL-23 both in vitro and in vivo, and is therefore being used in research related to autoimmune and infectious diseases.

[0004] Targeted protein degradation technology is currently widely used in drug development and is considered a major breakthrough in the field of small molecule drugs. Among them, protein-targeted chimeric degradation (PROTAC) research is the most mature. The PROTAC molecular structure consists of three parts: a target protein recognition ligand, a linker, and a ubiquitination E3 ligase that recognizes the ligand. PROTAC can effectively induce ubiquitination of target proteins and effectively degrade them through the proteasome pathway. Compared with traditional small molecule inhibitors, PROTAC molecules have the advantages of small dosage, low resistance to drug resistance, and high safety. Currently, multiple PROTAC molecules have entered clinical research.

[0040] Figure 1 shows the results of PIKfyve protein level detection in VCaP cells. DETAILED DESCRIPTION

[0041] After extensive and in-depth research, the inventors have developed a class of compounds capable of targeted ubiquitination and degradation of the PIKfyve protein, and pharmaceutical compositions thereof. These compounds can efficiently and selectively degrade PIKfyve protein in cells, and therefore have potential uses in treating conditions associated with abnormal PIKfyve protein expression. Based on these findings, the inventors completed the present invention.

[0042] the term

[0043] In the compounds described herein, when any variable (e.g., R1, R2, etc.) occurs more than once in any component, its definition at each occurrence is independent of its definition at every other occurrence. Likewise, combinations of substituents and variables are permitted so long as such combinations result in a stable compound. A line drawn from a substituent into the ring system indicates that the indicated bond may be attached to any substitutable ring atom. If the ring system is polycyclic, this means that such bonds are attached only to any suitable carbon atom of the adjacent ring. It will be understood that one of ordinary skill in the art can select the substituents and substitution patterns of the compounds of the present invention to provide chemically stable compounds that can be readily synthesized from readily available raw materials using techniques in the art and the methods set forth below. If a substituent is itself substituted with more than one group, it will be understood that these groups may be on the same carbon atom or on different carbon atoms so long as the structure is stable.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention belongs. The terms used in the description are for the purpose of describing particular embodiments only and are not intended to limit the invention.

[0045] The following terms are used to describe the present invention. Where a term is not specifically defined herein, it is given the art-recognized meaning by those of ordinary skill in the art in applying the term in the context of its use to describe the present invention.

[0046] As used herein, the term "ubiquitin ligase" refers to a family of proteins that promote the transfer of ubiquitin to a specific substrate protein, thereby targeting the substrate protein for degradation. For example, Von Hippel-Lindau E3 ubiquitin ligase or CRBN E3 ubiquitin ligase is a protein that, alone or in combination with an E2 ubiquitin conjugating enzyme, results in the attachment of ubiquitin to a lysine on a target protein, and subsequently targets a specific protein substrate for degradation by the proteasome. Thus, an E3 ubiquitin ligase, alone or in combination with an E2 ubiquitin conjugating enzyme, is responsible for the transfer of ubiquitin to a target protein. In general, the ubiquitin ligase participates in polyubiquitination, whereby a second ubiquitin is attached to a first ubiquitin; a third ubiquitin is attached to a second ubiquitin, and so on. Polyubiquitination marks a protein for degradation by the proteasome. However, there are some ubiquitination events that are limited to monoubiquitination, in which only a single ubiquitin is added to a substrate molecule by a ubiquitin ligase. Monoubiquitinated proteins are not targeted to the proteasome for degradation, but instead can be altered in their cellular location or function, for example, by binding to other proteins with domains capable of binding ubiquitin. Further complicating the situation is that different lysines on ubiquitin can be targeted by E3 to form chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin that is recognized by the proteasome.

[0047] As used herein, the term "alkyl" is intended to include both branched and straight-chain saturated aliphatic hydrocarbon groups having a specified number of carbon atoms. For example, the definition of "C1-C6 alkyl" includes groups having 1, 2, 3, 4, 5, or 6 carbon atoms in a straight or branched chain. For example, "C1-C6 alkyl" specifically includes methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, isobutyl, pentyl, and hexyl.

[0048] The term "cycloalkyl" as used herein refers to a saturated or partially unsaturated monocyclic, bicyclic or polycyclic hydrocarbon group whose ring atoms are composed of carbon atoms, and the bicyclic or polycyclic rings include spirocyclic, fused rings and bridged rings. For example, "cycloalkyl" includes but is not limited to the following groups: cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, wait.

[0049] The term "alkoxy" used herein refers to a group having an -O-alkyl structure, such as -OCH3, -OCH2CH3, -OCH2CH2CH3, -O-CH2CH(CH3)2, -OCH2CH2CH2CH3, -O-CH(CH3)2, etc.

[0050] As used herein, the term "heterocycloalkyl" refers to a saturated or partially unsaturated monocyclic, bicyclic or polycyclic cyclic substituent, wherein one or more ring atoms are selected from N, O or S(O)m (wherein m is an integer from 0 to 2) and the remaining ring atoms are carbon, and the bicyclic or polycyclic rings include spirocyclic, fused and bridged rings. For example: morpholinyl, piperidinyl, tetrahydropyrrolyl, pyrrolidinyl, dihydroimidazolyl, dihydroisoxazolyl, dihydroisothiazolyl, dihydrooxadiazolyl, dihydrooxazolyl, dihydropyrazinyl, dihydropyrazolyl, dihydropyridinyl, dihydropyrimidinyl, dihydropyrrolyl, dihydrotetrazolyl, dihydrothiadiazolyl, dihydrothiazolyl, dihydrothiophenyl, dihydrotriazolyl, dihydroazetidinyl, tetrahydrofuranyl, tetrahydrothiophenyl, etc., and N-oxides thereof. Attachment of the heterocyclic substituents can be achieved via a carbon atom or via a heteroatom.

[0051] In this application, unless otherwise specified, the term "ring" or "cyclic structure" is intended to include various forms of cyclic groups, including but not limited to: a saturated ring, a partially unsaturated but non-aromatic ring, or an aromatic ring (such as an aryl or heteroaryl group); in particular, the ring may be a monocyclic ring, or a polycyclic ring formed by multiple monocyclic rings, such as an aromatic or non-aromatic fused bicyclic ring, or a bridged or spirocyclic structure. Unless otherwise specified, the "ring" is intended to include (but not limited to) a cyclic structure selected from the following group: an aromatic ring (including a monocyclic or polycyclic ring such as a bicyclic ring), a heteroaromatic ring (including a monocyclic or polycyclic ring such as a bicyclic ring), a saturated or partially unsaturated carbocyclic ring (including a monocyclic or polycyclic ring such as a paracyclic, bridged or spirocyclic structure), and a saturated or partially unsaturated heterocyclic ring (including a monocyclic or polycyclic ring such as a paracyclic, bridged or spirocyclic structure).

[0052] As used herein, the term "aryl" refers to an aromatic ring group having a specific number of carbon atoms, such as C6-C 10 The aryl group represents an aromatic ring group having 6 to 10 carbon atoms, for example, a phenyl group, a naphthyl group or the like.

[0053] As used herein, the term "heteroaryl" refers to a cyclic aromatic group having a specific number of atoms, wherein 1-3 atoms are heteroatoms selected from N, S and O. For example, a 5-12 membered heteroaryl group represents an aromatic ring group having 5-12 carbon atoms. It can be a monocyclic ring or a condensed ring. Specific examples include pyridyl, pyridazinyl, pyrimidinyl, pyrazinyl, triazinyl, pyrrolyl, pyrazolyl, imidazolyl, (1,2,3)-triazolyl and (1,2,4)-triazolyl, tetrazolyl, furyl, thienyl, isoxazolyl, thiazolyl, oxazolyl, and the like.

[0054] Unless otherwise specified as "substituted or unsubstituted", the groups of the present invention may be substituted by substituents selected from the following groups: halogen, nitrile, nitro, hydroxyl, amino, C1-C6 alkyl-amino, C1-C6 alkyl, C2-C6 alkenyl, C2-C6 alkynyl, C1-C6 alkoxy, halogenated C1-C6 alkyl, halogenated C2-C6 alkenyl, halogenated C2-C6 alkynyl, halogenated C1-C6 alkoxy, allyl, benzyl, C6-C 12 Aryl, C1-C6 alkoxy-C1-C6 alkyl, C1-C6 alkoxy-carbonyl, phenoxycarbonyl, C2-C6 alkynyl-carbonyl, C2-C6 alkenyl-carbonyl, C3-C6 carbocyclyl-carbonyl, C1-C6 alkyl-sulfonyl, etc.

[0055] As will be understood by those skilled in the art, "halogen" or "halo" as used herein refers to chlorine, fluorine, bromine and iodine.

[0056] As used herein, the term "subject" refers to a mammal. For example, mammals encompassed by the present invention include humans, primates, and domesticated animals, such as cattle, sheep, pigs, horses, mice, rats, and humans.

[0057] The present disclosure also includes isotopically labeled compounds, which are identical to the compounds described in formula (I), except that one or more atoms are replaced by atoms having an atomic mass or mass number different from the atomic mass or mass number normally found in nature. Suitable isotopes for inclusion in the compounds of the present disclosure include hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine, such as, but not limited to, 2 H, 3 H, 13 C, 14 C, 15 N, 18 O, 31 P, 35 S, 18 F and 36 Cl. Using heavier isotopes such as deuterium (i.e. 2 H) substitution may offer certain therapeutic advantages due to greater metabolic stability, such as increased in vivo half-life or reduced dosage requirements, and therefore may be preferred in some cases. Positron-emitting isotopes may be added to the compounds for use in medical imaging and positron emission tomography (PET) studies to determine receptor distribution. Suitable positron-emitting isotopes that may be added to the compounds of formula (I) include 11 C, 13 N, 15 O, and 18 F. 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 herein, using an appropriate isotopically labeled reagent in place of a non-isotopically labeled reagent.

[0058] The compounds disclosed herein may be present in a pharmaceutically acceptable solvent, such as water, ethanol, or the like, in dissolved or undissolved form. In one embodiment, the compound is amorphous. In one embodiment, the compound is a single polymorph. In another embodiment, the compound is a mixture of polymorphs. In another embodiment, the compound is a crystalline form.

[0060] The present invention encompasses the free forms of the compounds of Formula I, as well as their pharmaceutically acceptable salts and stereoisomers. Certain specific exemplary compounds described herein are protonated salts of amine compounds. The term "free form" refers to the amine compounds in their non-salt form. Pharmaceutically acceptable salts encompassed include not only the exemplary salts of the specific compounds described herein, but also all typical pharmaceutically acceptable salts of the free forms of the compounds of Formula I. The free forms of specific salts of the compounds described can be isolated using techniques known in the art. For example, the free forms can be regenerated by treating the salts with a dilute aqueous base solution, such as dilute aqueous NaOH, dilute aqueous potassium carbonate, dilute aqueous ammonia, and dilute aqueous sodium bicarbonate. The free forms differ somewhat from their respective salt forms in certain physical properties, such as solubility in polar solvents, but for the purposes of the present invention, such acid and base salts are otherwise pharmaceutically equivalent to their respective free forms.

[0061] Pharmaceutically acceptable salts of the present invention can be synthesized from compounds of the present invention containing a basic or acidic moiety by conventional chemical methods. Typically, salts of basic compounds are prepared by ion exchange chromatography or by reacting a free base with a stoichiometric amount or an excess of an inorganic or organic acid in the desired salt form in a suitable solvent or combination of solvents. Similarly, salts of acidic compounds are formed by reaction with a suitable inorganic or organic base.

[0062] Therefore, pharmaceutically acceptable salts of the compounds of this invention include conventional non-toxic salts of the compounds of this invention formed by reacting an alkaline compound of this invention with an inorganic or organic acid.
