Definitions
- TNIK Traf2-and Nck-interacting protein kinase
- TNIK A biologically active enzyme known as Traf2-and Nck-interacting protein kinase is an enzyme commonly known as the TNIK in humans, and which is encoded by the TNIK gene.
- TNIK as a serine/threonine kinase is involved in various biological processes. There is a need for new drug candidates that can target TNIK.
- TNIK kinase inhibitors
- intermediates used in the methods.
- TNIK is a serine/threonine kinase that is involved in various biological processes including acting as an essential regulatory component of the Wnt signaling pathway.
- TNIK can directly bind TCF4 and b-catenin and phosphorylates TCF4.
- TNIK can play an activator of Wnt target gene expression and modulates the actin cytoskeleton and activates the c-Jun N-terminal kinase pathway, which is responsive to stress.
- TNIK neuronal dendrite extension and arbonization during development. More generally, TNIK may play a role in cytoskeletal rearrangement and regulate cell spreading. TNIK also causes weak Smad1 T322 phosphorylation, involved in TGF-b1 signaling transduction.
- TNIK is considered to be a germinal center kinase (GCK) , which can be characterized by an N-terminal kinase domain and a C-terminal GCK domain that serves a regulatory function.
- GCK germinal center kinase
- TNIK activation of Wnt signaling can play important roles in carcinogenesis and embryonic development. Mutations in this gene are associated with an autosomal recessive form of cognitive disability.
- TNIK is linked to cancer, including for example, colorectal cancer. As such, TNIK has been identified as an attractive candidate for drugs targeting certain cancers.
- TNIK is a potential target for the generation of small molecule inhibitors to specifically block the Wnt pathway in disease states such as colorectal cancer or the autosomal recessive form of cognitive disability.
- therapeutic targets associated with EMT such as TNIK being target for inhibition, can be used for therapies for treating and/or preventing EMT-based disorders, such as cancer metastasis and fibrosis.
- TNIK inhibitor that can inhibit the kinase activity of TNIK, as a member of the Ste20 family of MAP kinase kinase kinase (MAP4K) .

Description
CROSS REFERENCE TO RELATED APPLICATIONS
This international patent application claims the benefit of International Application No. PCT/CN2022/114447, filed August 24, 2022, which is incorporated herein by reference in its entirety.
A biologically active enzyme known as Traf2-and Nck-interacting protein kinase is an enzyme commonly known as the TNIK in humans, and which is encoded by the TNIK gene. TNIK as a serine/threonine kinase is involved in various biological processes. There is a need for new drug candidates that can target TNIK.
In one aspect, described herein are methods of making kinase inhibitors (e.g., TNIK inhibitors) and intermediates used in the methods. TNIK is a serine/threonine kinase that is involved in various biological processes including acting as an essential regulatory component of the Wnt signaling pathway. TNIK can directly bind TCF4 and b-catenin and phosphorylates TCF4. Additionally, TNIK can play an activator of Wnt target gene expression and modulates the actin cytoskeleton and activates the c-Jun N-terminal kinase pathway, which is responsive to stress. It is also part of a signaling complex composed of NEDD4, RAP2A, and TNIK, which regulates neuronal dendrite extension and arbonization during development. More generally, TNIK may play a role in cytoskeletal rearrangement and regulate cell spreading. TNIK also causes weak Smad1 T322 phosphorylation, involved in TGF-b1 signaling transduction.
TNIK is considered to be a germinal center kinase (GCK) , which can be characterized by an N-terminal kinase domain and a C-terminal GCK domain that serves a regulatory function.
TNIK activation of Wnt signaling can play important roles in carcinogenesis and embryonic development. Mutations in this gene are associated with an autosomal recessive form of cognitive disability.
Additionally, TNIK is linked to cancer, including for example, colorectal cancer. As such, TNIK has been identified as an attractive candidate for drugs targeting certain cancers.
The current data may imply TNIK is a potential target for the generation of small molecule inhibitors to specifically block the Wnt pathway in disease states such as colorectal cancer or the autosomal recessive form of cognitive disability.
Also, therapeutic targets associated with EMT, such as TNIK being target for inhibition, can be used for therapies for treating and/or preventing EMT-based disorders, such as cancer metastasis and fibrosis.
Accordingly, it would be advantageous to have a TNIK inhibitor that can inhibit the kinase activity of TNIK, as a member of the Ste20 family of MAP kinase kinase kinase (MAP4K) .

Table 1 Exemplary Compounds
Included in the present disclosure are salts, particularly pharmaceutically acceptable salts, of the compounds described herein. The compounds of the present disclosure that possess a sufficiently acidic, a sufficiently basic, or both functional groups, can react with any of a number of inorganic bases, and inorganic and organic acids, to form a salt. Alternatively, compounds that are inherently charged, such as those with a quaternary nitrogen, can form a salt with an appropriate counterion, e.g., a halide such as bromide, chloride, or fluoride, particularly bromide.
Chemical entities having carbon-carbon double bonds or carbon-nitrogen double bonds may exist in Z-or E-form (or cis-or trans-form) . Furthermore, some chemical entities may exist in various tautomeric forms. Unless otherwise specified, compounds described herein are intended to include all Z-, E-and tautomeric forms as well.
A “tautomer” refers to a molecule wherein a proton shift from one atom of a molecule to another atom of the same molecule is possible. The compounds presented herein, in certain embodiments, exist as tautomers. In circumstances where tautomerization is possible, a chemical equilibrium of the tautomers will exist.

In certain embodiments, compounds or salts of the compounds may be prodrugs, e.g., wherein a hydroxyl in the parent compound is presented as an ester or a carbonate, or carboxylic acid present in the parent compound is presented as an ester. The term “prodrug” is intended to encompass compounds which, under physiologic conditions, are converted into pharmaceutical agents of the present disclosure. One method for making a prodrug is to include one or more selected moieties which are hydrolyzed under physiologic conditions to reveal the desired molecule. In other embodiments, the prodrug is converted by an enzymatic activity of the host animal such as specific target cells in the host animal. For example, esters or carbonates (e.g., esters or carbonates of alcohols or carboxylic acids and esters of phosphonic acids) are preferred prodrugs of the present disclosure.
Prodrug forms of the herein described compounds, wherein the prodrug is metabolized in vivo to produce a compound as set forth herein are included within the scope of the claims. In some cases, some of the herein-described compounds may be a prodrug for another derivative or active compound.
Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. Prodrugs may help enhance the cell permeability of a compound relative to the parent drug. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. Prodrugs may be designed as reversible drug derivatives, for use as modifiers to enhance drug transport to site-specific tissues or to increase drug residence inside of a cell.
In some embodiments, the design of a prodrug increases the lipophilicity of the pharmaceutical agent. In some embodiments, the design of a prodrug increases the effective water solubility. See, e.g., Fedorak et al., Am. J. Physiol., 269: G210-218 (1995) ; McLoed et al., Gastroenterol, 106: 405-413
