BIFUNCTIONAL COMPOUNDS FOR TARGETING PKMYT1 AND METHODS OF USE
[0001] CROSS REFERENCE TO RELATED APPLICATION
[0002] This patent application claims the benefit of International Application No. PCT / CN2023 / 114462, filed August 23, 2023; and International Application No. PCT / CN2024 / 090754, filed April 30, 2024; which are incorporated herein by reference in their entirety.TECHNICAL FIELD
[0003] The present disclosure generally relates to a bifunctional compound comprising a targeting moiety for binding protein kinase, membrane associated tyrosine / threonine 1 (PKMYT1) , a pharmaceutical composition thereof and a method for the treatment of disorders or diseases associated with PKMYT1.BACKGROUND OF THE INVENTION
[0004] PKMYT1 (or Myt1) is a member of the Wee family and was first reported as a kinase capable of phosphorylating Cdc2 efficiently on both threonine-14 and tyrosine-15 in a Xenopus frog. PKMYT1 inhibits cell cycle progression by inhibiting the activities of cell cycle-associated proteins, such as Cyclin A, CDK1, and CDK2. PKMYT1 also drives the progression of a variety of tumors. Studies have shown that premature activation of cdc2 leads to mitotic catastrophe and cell death. Inhibition of Myt1 is predicted to cause premature activation of cdc2, and thus would kill rapidly proliferating cells. In addition, Myt1 inhibition is predicted to reduce resistance to conventional DNA-damaging chemotherapeutics, because the mechanisms by which cells avoid death involve arrest in the G2 phase of the cell cycle, and repair or DNA damage prior to division. That arrest should be prevented by blocking Myt1 inhibitory phosphorylation of cdc2. Thus, forcing the cell to enter mitosis prematurely. Myt1 kinase is an important cell cycle regulator, particularly at the G2 / M phase. Inhibition of Myt1 could in and of itself have therapeutic benefit in reducing tumor proliferation, and in addition, could be used in conjunction with conventional chemotherapies to overcome drug resistance.
[0005] In recent years, an alternative potential therapeutic approach, i.e., induced protein degradation, has emerged. This therapeutic approach is best exemplified by Proteolysis Targeting Chimeras (PROTACs) , which are heterobifunctional molecules that work by creating a trimeric complex between a target protein and an E3 ubiquitin ligase, thus facilitating target ubiquitination and subsequent degradation.
[0006] There is still ongoing need in the art for effective treatments for diseases and conditions that are related to PKMYT1 regulation or activity, such as cancer.SUMMARY OF THE INVENTION

[0019] DEFINITIONS
[0020] In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments. Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is, as “including, but not limited to. ” Further, headings provided herein are for convenience only and do not interpret the scope or meaning of the claimed invention.
[0021] Reference throughout this specification to “some embodiments” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Also, as used in this specification and the appended claims, the singular forms “a, ” “an, ” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its sense including “and / or” unless the content clearly dictates otherwise.
[0022] It must be noted that, as used in the specification and the appended claims, the singular forms “a, ” “an, ” and “the” include plural forms of the same unless the context clearly dictates otherwise. Thus, for example, reference to “a compound” includes a plurality of compounds. In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings unless a contrary intention is apparent.
[0023] Definitions of specific functional groups and chemical terms are described in more detail below. For purposes of this disclosure, the chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75th Ed., inside cover, and specific functional groups are generally defined as described therein. Additionally, general principles of organic chemistry, as well as specific functional moieties and reactivity, are described in Organic Chemistry, Thomas Sorrell, University Science Books, Sausalito, 1999; Smith and March March’s Advanced Organic Chemistry, 5th Edition, John Wiley &Sons, Inc., New York, 2001; Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York, 1989; Carruthers, Some Modern Methods of Organic Synthesis, 3rd Edition, Cambridge University Press, Cambridge, 1987; the entire contents of each of which are incorporated herein by reference.
[0024] At various places in the present disclosure, linking substituents are described. Where the structure clearly requires a linking group, the Markush variables listed for that group are understood to be linking groups. For example, if the structure requires a linking group and the Markush group definition for that variable lists “alkyl” , then it is understood that the “alkyl” represents a linking alkylene group.
[0025] When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom in the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such formula. Combinations of substituents and / or variables are permissible, but only if such combinations result in stable compounds.
[0026] When any variable (e.g., Ri) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 Ri moieties, then the group may optionally be substituted with up to two Ri moieties and Ri at each occurrence is selected independently from the definition of Ri. Also, combinations of substituents and / or variables are permissible, but only if such combinations result in stable compounds.
[0027] As used herein, a dash “-” at the front or end of a chemical group is used, a matter of convenience, to indicate a point of attachment for a substituent. For example, -OH is attached through the oxygen atom; chemical groups may be depicted with or without one or more dashes without losing their ordinary meaning. A wavy line drawn through a line in a structure indicates a point of attachment of a group. Unless chemically or structurally required, no directionality is indicated or implied by the order in which a chemical group is written or named. As used herein, a solid line coming out of the center of a ring indicates that the point of attachment for a substituent on the ring can be at any ring atom. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such formula. Combinations of substituents and / or variables are permissible, but only if such combinations result in stable compounds.
[0028] Recitation of ranges of values are merely intended to serve as a shorthand method of referring individually to each separate value falling within the range, unless otherwise indicated herein, and each separate value is incorporated into the specification as if it were individually recited herein. A range used herein, unless otherwise specified, includes the two limits of the range. For example, the expressions “n is an integer between 1 and 6” and “n being an integer of 1 to 6” both mean “n being 1, 2, 3, 4, 5, or 6” .
[0029] As used herein, the term “compounds provided herein” , or “compounds disclosed herein” or “compounds of the present disclosure” refers to the compounds of Formula (I) , Formula (II) , Formula (III) , Formula (IV) , Formula (V) as well as the specific compounds disclosed herein.

For examples, C1-6 indicates a range of one to six carbon atoms, including one carbon atom, two carbon atoms, three carbon atoms, four carbon atoms, five carbon atoms and six carbon atoms. In some embodiments, the term “C1-12” indicates 1 to 12, particularly 1 to 10, particularly 1 to 8, particularly 1 to 6, particularly 1 to 5, particularly 1 to 4, particularly 1 to 3 or particularly 1 to 2 carbon atoms.

[0047] The term “partially saturated” refers to a radical that includes at least one double or triple bond, and is intended to encompass rings having multiple sites of unsaturation, but is not intended to include aromatic (i.e., fully unsaturated) moieties.
[0048] As used herein, the term “heteroatom” refers to nitrogen, oxygen, sulfur or phosphorus, and includes any oxidized form of nitrogen, sulfur or phosphorus, and any quaternized form of a basic nitrogen.
[0049] “Hydroxy” or “hydroxyl” , whether as part of another term or used independently, refers to -OH.
[0050] The term “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted alkyl” means either “alkyl” or “substituted alkyl” as defined above. Further, an optionally substituted group may be un-substituted (e.g., -CH2CH3) , fully substituted (e.g., -CF2CF3) , mono-substituted (e.g., -CH2CH2F) or substituted at a level anywhere in-between fully substituted and mono-substituted (e.g., -CH2CHF2, -CH2CF3, -CF2CH3, -CFHCHF2, etc. ) . 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 and / or synthetically non-feasible. Thus, any substituents described should generally be understood as having a maximum molecular weight of about 1,000 daltons, and more typically, up to about 500 daltons.
[0051] The term “one or more” when referring to an optional substituent means that the subject group is optionally substituted with one, two, three, four substituents, or more substituents. In some embodiments, the subject group is optionally substituted with one, two, three, or four substituents. In some embodiments, the subject group is optionally substituted with one, two, or three substituents. In some embodiments, the subject group is optionally substituted with one or two substituents. In some embodiments, the subject group is optionally substituted with one substituent. In some embodiments, the subject group is optionally substituted with two substituents.
[0052] As used herein, the term “oxo” refers to the group (=O) or (O) .
[0053] As used herein, the term “substituted” , whether preceded by the term "optionally" or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent. It will be understood that “substitution” or “substituted with” includes the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and that the substitution results in a stable or chemically feasible compound, e.g., which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, etc. Unless otherwise indicated, an “optionally substituted” group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. The substituents may include, but not limited to, alkyl, alkenyl, alkynyl, alkoxy, acyl, amino, amido, amidino, aryl, azido, carbamoyl, carboxyl, carboxyl ester, cyano, guanidino, halo, haloalkyl, heteroalkyl, heteroaryl, heterocyclyl, hydroxy, hydrazino, imino, oxo, nitro, alkylsulfinyl, sulfonic acid, alkylsulfonyl, thiocyanate, thiol, thione, or combinations thereof. It will be understood by those skilled in the art that substituents can themselves be substituted, if appropriate. Unless specifically stated as “unsubstituted” , references to chemical moieties herein are understood to include substituted variants. For example, reference to an “aryl” group or moiety implicitly includes both substituted and unsubstituted variants.
[0054] As used herein, the term “ubiquitin ligase” refers to a family of proteins that facilitate the transfer of ubiquitin to a specific substrate protein, targeting the substrate protein for degradation. By way of example, Von Hippel-Lindau E3 Ubiquitin Ligase is a protein that alone or in combination with an E2 ubiquitin-conjugating enzyme causes the attachment of ubiquitin to a lysine on a target protein, and subsequently targets the specific protein substrates for degradation by the proteasome. Thus, E3 ubiquitin ligase alone or in complex with an E2 ubiquitin conjugating enzyme is responsible for the transfer of ubiquitin to targeted proteins. In general, the ubiquitin ligase is involved in polyubiquitination such that a second ubiquitin is attached to the first; a third is attached to the second, and so forth. Polyubiquitination marks proteins for degradation by the proteasome. However, there are some ubiquitination events that are limited to mono-ubiquitination, in which only a single ubiquitin is added by the ubiquitin ligase to a substrate molecule. Mono-ubiquitinated proteins are not targeted to the proteasome for degradation, but may instead be altered in their cellular location or function, for example, via binding other proteins that have domains capable of binding ubiquitin. Further complicating matters, different lysines on ubiquitin can be targeted by an E3 to make chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin, which is recognized by the proteasome.
