NOVEL COMPOUNDS AS MYT1 INHIBITORS AND USES THEREOFCROSS REFERENCE
[0001] This patent application claims the benefit of International Application No. PCT / CN2024 / 132278, filed November 15, 2024, and International Application No. PCT / CN2025 / 094024, filed on May 9, 2025; which are incorporated herein by reference in their entirety. FIELD OF THE DISCLOSURE
[0002] The present disclosure relates to novel compounds or pharmaceutically acceptable salts thereof, which are useful as a membrane-associated tyrosine and threonine-specific cdc2-inhibitory kinase (MYT1) (Gene name PKMYT1) inhibitor. The present disclosure further relates to pharmaceutical compositions comprising one or more of such compounds or pharmaceutically acceptable salts thereof as an active ingredient, and use of such compounds or pharmaceutically acceptable salts thereof in the treatment of diseases or disorders.BACKGROUND
[0003] Cdc2 is the cyclin-dependent kinase that controls entry of cells into mitosis. Phosphorylation of Cdc2 on threonine-14 and tyrosine-15 inhibits the activity of the enzyme and prevents premature initiation of mitosis. MYT1, a member of the Wee1 family, is a membrane-associated inhibitory kinase that phosphorylates Cdc2 on both threonine-14 and tyrosine-15. MYT1 activity is highly regulated during the cell cycle, suggesting that this relative of Wee1 plays a role in mitotic control.

[0014] The novel features of the present disclosure are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present disclosure will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the present disclosure are utilized, and the accompanying drawings of which:
[0015] Figure 1 shows immunoblotting analysis for effect of Compounds 20-P1 and 6-A on TGF-β-induced EMT assay in A549 cells.
[0016] Figure 2 shows immunoblotting analysis for effect of Compounds 6-A and 20-P1 on TGF-β-induced FMT assay in LX-2 cells.DETAILED DESCRIPTIONDefinitions
[0017] In the following description, certain specific details are set forth 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.
[0018] 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.
[0019] The terms below, as used herein, have the following meanings, unless indicated otherwise.
[0020] 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, 2nd Edition, University Science Books, Sausalito, 2006; Smith and March March’s Advanced Organic Chemistry, 6th Edition, John Wiley &Sons, Inc., New York, 2007; Larock, Comprehensive Organic Transformations, 3rd Edition, VCH Publishers, Inc., New York, 2018; Carruthers, Some Modern Methods of Organic Synthesis, 4th Edition, Cambridge University Press, Cambridge, 2004; the entire contents of each of which are incorporated herein by reference.
[0021] 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 which may connect to two or more other 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. For example, the term “alkyl” may connect to one, two or three other group (s) , as required by Markush structures.
[0022] 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.
[0023] 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.
[0024] As used herein, the term “Ci-Cj” indicates a range of the carbon atoms numbers, wherein i and j are integers and the range of the carbon atoms numbers includes the endpoints (i.e. i and j) and each integer point in between, and wherein j is greater than i. For examples, C1-C6 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.

HCC1569 cells were plated in a 384-well plate (Corning, #354663) at 4000 cells in 40 μL of medium per well and incubated in a humidified incubator at 37 ℃ and 5%CO2 for 44 hours. The next day, 40 nL of diluted compounds or DMSO were added using the Echo 655 liquid handler, and the plate was placed in the incubator for 6 hours. Next, 40 μL of 8%fixative solution (Solarbio, #P1112) was added per well and incubated at room temperature for 20 mins to fix cells. Cells were then washed twice with PBS (Solarbio, #P1020) and permeabilized with 40 μL of methanol (Innochem, #M6600) per well. Cells were washed twice more with PBS and blocked with 20 μL of Blocking Buffer (LI-COR, #927-70001) at room temperature for 1 hour. Blocking Buffer was then removed, and cells were probed with 1: 1000 diluted anti-CDK1 (phospho T14) antibody (Abcam, #ab58509) in Blocking Buffer at 4℃ overnight. The next day, cells were washed three times with PBST (Solarbio, #P1033) for 5 minutes each, and then incubated with 20 μL of mixtures of 1: 1000 diluted IRDye 800CW Goat anti-Rabbit IgG (H+L) (LI-COR, #926-32211) and 1: 1000 diluted CellTagTM 700 Stain (LI-COR, #926-41090) in Blocking Buffer (LI-COR, #927-70001) at room temperature for 1 hour in the dark. Cells were washed again three times with PBST for 5 minutes each. The plate was then centrifuged upside-down at 1000 rpm for 1 minute and scanned using an Odyssey CLx.

[0206] All cell lines were cultured at 37 ℃ in a humidified atmosphere of 95%air and 5%CO2. A549 (ATCC) cells were cultured in RPMI-1640 medium with 10%FBS and 1%penicillin-streptomycin. LX-2 (ATCC) cells were cultured in DMEM medium with 10%FBS and 1%penicillin-streptomycin. MRC-5 (ATCC) cells were cultured in MEM medium with 10%FBS, 1%non-essential amino acids and 1 mM sodium pyruvate and 1%penicillin-streptomycin. All cell lines were tested and confirmed to be free of mycoplasma contamination.
[0207] TGF-β-induced EMT assay in A549 cells
[0208] A549 cells were seeded in six-well plates at 3 × 105 cells per well. After overnight culture, cells were treated with test compounds at three concentrations for 30 min, followed by stimulation with 10 ng / mL TGF-β for 72 h. TGF-β stimulation served as the maximal induction positive control. After induction, the culture medium was discarded, and cells were washed once with PBS. RIPA lysis buffer (Beyotime, #P0013B) supplemented with 1%protease inhibitor cocktail (Beyotime, #P1005) was then added to lyse the cells on ice or at 4℃ for 20 min, with gentle tapping of the plate every 10 minutes to ensure thorough lysis. The lysate was collected using a cell scraper and centrifuged at 14, 000 rpm and 4℃ for 15 min. The supernatant was collected and stored at -80℃ for subsequent immunoblotting analysis.
[0209] TGF-β-induced FMT assay in LX-2 cells
[0210] LX-2 cells were seeded in six-well plates at 4 × 105 cells per well. After overnight culture, the medium was replaced with 0.5%FBS medium, and cells were starved for 24 h. Afterwards, cells were treated with test compounds at three concentrations for 30 min, followed by stimulation with 10 ng / mL TGF-β for 48 h. After induction, the culture medium was discarded, and cells were washed once with PBS. RIPA lysis buffer (Beyotime, #P0013B) supplemented with 1%protease inhibitor cocktail (Beyotime, #P1005) was then added to lyse the cells on ice or at 4℃ for 20 min, with gentle tapping of the plate every 10 minutes to ensure thorough lysis. The lysate was collected using a cell scraper and centrifuged at 14, 000 rpm and 4℃for 15 min. The supernatant was collected and stored at -80℃ for subsequent immunoblotting analysis.
[0211] Immunoblotting
[0212] The protein concentrations of the cell lysates were determined using the PIERCE BCA Protein Assay Kit (Invitrogen, #23225) . Following denaturation, samples were loaded onto 4–20%gradient Bis-Tris gels (GenScript, #M42012C) for protein separation by SDS-PAGE. After electrophoresis, proteins were transferred onto nitrocellulose membranes (Invitrogen, #IB23001) . The membranes were blocked with 3%BSA (Beyotime, #ST023-200G) in TBST buffer at room temperature for 1 h and then incubated with primary antibodies at 4℃ overnight.
[0213] After primary antibody incubation, the membranes were washed three times with TBST buffer and subsequently incubated with HRP-conjugated secondary antibodies at room temperature for 1 h. Blot images were captured using the Azure Biosystems C300 imaging system. Quantitative analysis was performed using AzureSpot Pro software.
