[0001] This application claims priority to International Patent Application Nos. PCT / CN2024 / 074116, filed on January 25, 2024, and PCT / CN2024 / 118474, filed on September 12, 2024, the entirety of each of which is incorporated herein by reference.2. FIELD
[0002] In some embodiments, provided herein are certain aminoheteroaryl compounds with tricyclic structure moiety, compositions comprising the same, methods of preparing and methods of using the same, e.g., for inhibiting cyclin-dependent kinases and / or for treating or preventing various diseases or disorders provided herein.3. BACKGROUND
[0003] Unrestrained cell growth is the hall mark of cancer and disrupted cell-cycle regulation is a common feature in malignant cells. Cyclin-dependent kinases (CDKs) are a family of serine / threonine protein kinases that regulate mammalian cell division and proliferation. At least 20 CDKs and 29 cyclins have been identified in human cells (Cao et. al., BMC Evol. Biol, 2014; 14: 10) . In addition to regulate cell cycle progression, these CDKs and cyclins also play important roles in regulating transcription, DNA repair, differentiation and apoptosis (Palmer and Kaldis, Semin Cell Dev Biol, 2020; 107: 54-62) .
[0004] CDK4 and CDK6 are key regulators for G1-Stransition. D type cyclins form complexes with CDK4 / 6 and phosphorylates the retinoblastoma (Rb) protein. This relieves the Rb-mediated inhibition of the transcription factor E2F and leads to S phase entrance. CDK4 / 6-CyclinD-Rb pathway is frequently perturbed in human cancers. Amplification of CDK4 / 6 and Cyclin D1, over-expression of D type cyclins, mutation, genetic deletion, or transcriptional silencing of endogenous CDK4 / 6 inhibitor p16 (CDKN2A) have all been reported as mechanisms which leads to pathway activation (Dickson, Mol Cancer Res. 2014; 20: 3379-3383) . In breast cancer, dysregulation of CDK4 / 6 pathway is associated with resistance to endocrine therapy (Ding et. al., Int J Mol Sci. 2020; 21: 1960) .
[0005] In recent years, targeted inhibition of CDKs has shown considerable therapeutic benefit in a variety of tumor types. The use of CDK4 / 6 inhibitors together with endocrine therapies were shown to be effective in treating human epidermal growth factor 2 (HER2) negative, estrogen receptor (ER) positive breast cancer. As a result, there different CDK4 / 6 inhibitors, palbociclib, ribociclib and abemaciclib were approved in combination with endocrine therapies in both first or second line setting (Cogliati, et. al., Life, 2022; 12: 378) . Most recently abemaciclib is also approved for adjuvant treatment of early breast cancer.
[0006] Despite the success of CDK4 / 6 inhibitors in clinic, treatment related adverse effects, especially hematologic toxicity such as neutropenia, prevented continued dosing of CDK4 / 6 inhibitors. Currently, both Palbociclib and Ribociclib are administrated on a three week on / one week off schedule. Mouse genetic and other emerging data suggest that the observed hematologic toxicity is likely linked to CDK6-cyclin D3 inhibition (Sicinska et. al., Mol Cell Biol, 2006; 26: 8052-8060; Cooper et. al., Nat Immunol, 2006; 5: 489-497) . On the other hand, CDK6-cyclin D3 is expressed at very low level in HR+ / HER2-breast cancer and CDK4 was identified as the oncogenic driver in this tumor type (Zhang et. al., Cancer Res, 2022; epub) .4. SUMMARY
[0007] Inhibitors specific to a particular CDK such as CDK4 may have the advantage of improved safety profile and may enable improved dosing schedule and higher dosing, and may lead to deeper target inhibition, better efficacy and potentially overcome drug resistance. There remains a need for CDK inhibitors, such as selective CDK4 inhibitors, such as those with improved efficacy and reduced side effects in clinic.

When a -N (R#) (R#) group has two R#other than hydrogen, they can be combined with the nitrogen atom to form a ring. In some embodiments, the ring is a 3-, 4-, 5-, 6-, 7-, or 8-membered ring. In some embodiments, one or more ring atoms are heteroatoms independently selected from nitrogen, oxygen, sulfur, boron, phosphorus, and silicon. The term “amino” also includes N-oxide (–N+ (R#) (R#) O-) . In certain embodiments, each R#or the ring formed by -N (R#) (R#) independently may be unsubstituted or substituted with one or more substituents.

In general, the term “substituted” , whether preceded by the term “optionally” or not, means that at least one hydrogen present on a group (e.g., a carbon or nitrogen atom) is replaced with a permissible substituent, e.g., a substituent which upon substitution results in a stable compound, e.g., a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction. Unless otherwise indicated, a “substituted” group has a substituent at one or more substitutable positions of the group, and when more than one position in any given structure is substituted, the substituent can be the same or different at each position. In some embodiments, when substituted, the optionally substituted groups provided herein can be substituted with 1-5 substituents. Substituents can be a carbon atom substituent, a nitrogen atom substituent, an oxygen atom substituent or a sulfur atom substituent, as applicable, each of which can be optionally isotopically labeled, such as deuterated. Two of the optional substituents can join to form a ring structure, such as an optionally substituted cycloalkyl, heterocylyl, aryl, or heteroaryl ring. Substitution can occur on any available carbon, oxygen, or nitrogen atom, and can form a spirocycle.
[0045] As used herein, and unless otherwise specified, the permissible substituents provided herein include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and non-aromatic substituents of organic compounds.

[0054] As used herein, and unless otherwise specified, the term “isomer” refers to different compounds that have the same molecular formula. “Stereoisomers” are isomers that differ only in the way the atoms are arranged in space. “Atropisomers” are stereoisomers from hindered rotation about single bonds. “Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A mixture of a pair of enantiomers in any proportion can be known as a “racemic” mixture. “Diastereoisomers” are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other. The absolute stereochemistry can be specified according to the Cahn-Ingold-Prelog R-Ssystem. When a compound is an enantiomer, the stereochemistry at each chiral carbon can be specified by either R or S. Resolved compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextro-or levorotatory) which they rotate plane polarized light at the wavelength of the sodium D line. However, the sign of optical rotation, (+) and (-) , is not related to the absolute configuration of the molecule, R and S. Certain compounds provided herein contain one or more asymmetric centers and can thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that can be defined, in terms of absolute stereochemistry at each asymmetric atom, as (R) -or (S) -. The present chemical entities, pharmaceutical compositions and methods are meant to include all such possible isomers, including racemic mixtures, optically substantially pure forms and intermediate mixtures. Optically active (R) -and (S) -isomers can be prepared, for example, using chiral synthons or chiral reagents, or resolved using conventional techniques.
[0055] As used herein, and unless otherwise specified, the term “enantiomeric purity” or “enantiomer purity” refers to a qualitative or quantitative measure of a purified enantiomer. The enantiomeric purity of compounds provided herein may be described in terms of enantiomeric excess (ee) , which indicates the degree to which a sample contains one enantiomer in greater amounts than the other. A racemic mixture has an ee of 0%, while a single completely pure enantiomer has an ee of 100%. Examples of the enantiomeric purity include an ee of at least about 10%, at least about 12%, at least about 14%, at least about 16%, at least about 18%, at least about 20%, at least about 22%, at least about 24%, at least about 26%, at least about 28%, at least about 30%, at least about 32%, at least about 34%, at least about 36%, at least about 38%, at least about 40%, at least about 42%, at least about 44%, at least about 46%, at least about 48%, at least about 50%, at least about 52%, at least about 54%, at least about 56%, at least about 58%, at least about 60%, at least about 62%, at least about 64%, at least about 66%, at least about 68%, at least about 70%, at least about 72%, at least about 74%, at least about 76%, at least about 78%, at least about 80%, at least about 81%, at least about 82%, at least about 83%, at least about 84%, at least about 85%, at least about 86%, at least about 87%, at least about 88%, at least about 89%, at least about 90%, at least about 91%, at least about 92%, at least about 93%, at least about 94%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about or at least about 99%.

[0416] LC-MS and 1H NMR, and de and / or ee values as applicable, for additional exemplary compounds which were prepared using similar synthetic methodology and routes are provided in the table below. Example S1.9- (5-chloro-2- ( ( (3S, 4R) -3-hydroxytetrahydro-2H-pyran-4-yl) amino) pyrimidin-4- yl) -7-fluoro-3, 3-dimethyl-1, 2, 3, 4-tetrahydro-6H-pyrimido [1, 6-a] quinolin-6-one (S1)
[0417] Starting from reagents S1.1 and S1.2, pyridone derivative S1.4 is obtained via cyclization of S1.3. The pyridone moiety is converted into S1.6 of methoxy substitution via S1.5 of chloro substitution. S1.6 is converted into boronic acid ester S1.7, which is coupled with the trichlorosusbtituted pyrimidine to give S1.8. S1.8 is brominated via the m-CPBA / POBr3 procedure. S1.9 is coupled to give S1.10, which is converted into tertiary alcohol S1.11. After demethylation of S1.11 to give S1.12, the tertiary alcohol is converted into corrsponding tertiary amine S1.14 via intermediate S1.13. Condensation with formaldehyde gives S1.15, which is converted into S1 by substitution with the cyclic amine. Example S2.9- (5-chloro-2- ( ( (3S, 4R) -3-hydroxytetrahydro-2H-pyran-4-yl) amino) pyrimidin-4- yl) -7-fluoro-1, 1, 3, 3-tetramethyl-2, 3-dihydrobenzo [c] [2, 6] naphthyridin-4 (1H) -one (S2)
[0418] Intermediate S2.2 is made by ring-opening esterification of S2.1. Oxidation of the hydroxy group in S2.2 gives the aldehyde S2.3, which is converted into the alkyne S2.4 by reacting with (1-diazo-2-oxopropyl) phosphonate. The primary alcohol S2.5 is synthesized by reacting S2.4 with formaldehyde under basic conditions. Subsequent functional transformation leads to corresponding brominated intermediate S2.6, which is linked with the disubstituted aniline to give S2.7. Intermediate S2.7 serves as the cyclization precursor to the substituted quinoline S2.8, in turn serves as the precursor for cyclization to give the tricyclic S2.9. Coupling with trichlorinated pyrimidine is carried out via the boronic ester intermediate S2.10 to give intermediate S2.11, which is substituted to give the terminal product S2. Example S3. (3S, 4R) -4- ( (5-chloro-4- (4, 4, 7-trifluoro-1, 1, 3, 3-tetramethyl-1, 2, 3, 4- tetrahydrobenzo [c] [2, 6] naphthyridin-9-yl) pyrimidin-2-yl) amino) tetrahydro-2H-pyran-3-ol (S3)
[0419] Intermediate S2.11 is florinated with diethylaminosulfur trifluoride (DAST) to give intermediate S3.1, which upon substitution leads to S3. Example S4. (3S, 4R) -4- ( (5-chloro-4- (7-fluoro-1, 1, 3, 3-tetramethyl-1, 2, 3, 4- tetrahydrobenzo [c] [2, 6] naphthyridin-9-yl) pyrimidin-2-yl) amino) tetrahydro-2H-pyran-3-ol (S4)
[0420] Reduction of the carbonyl of S2.11 gives intermediate S4.2 by two steps. S4.2 is substituted to give the terminal product S4. Example S5. (3S, 4R) -4- ( (5-chloro-4- (6-fluoro-1, 1, 3, 3-tetramethyl-1, 2, 3, 4- tetrahydroimidazo [1, 2-a: 5, 4-c'] dipyridin-8-yl) pyrimidin-2-yl) amino) tetrahydro-2H-pyran-3-ol (S5)
