Description

Pyrazolopyridine compounds and their uses Technical Field

[0001] This invention belongs to the field of medicine, specifically relating to a class of novel pyrazolopyridine compounds that inhibit CLK and / or DYRK, and methods and uses thereof for the prevention and / or treatment of diseases or symptoms related to or mediated by abnormal CLK and / or DYRK activity. Technical Background

[0002] CDC-like kinases (CLKs) and dual-specificity tyrosine-regulated kinases (DYRKs) belong to the CMGC (containing CDK, MAPK, GSK3, and CLK) kinase group.

[0003] The CLK family comprises four members: CLK1, CLK2, CLK3, and CLK4. CLKs can catalyze the serine and arginine-rich splicing factor 1-12 (SRSF1-12) (Aubol, BE et al. Mol. Cell, 2016, 63, 218-228), thereby regulating RNA splicing kinases. Since mRNA splicing is a key mechanism for proteomic diversity and plays an essential role in various biological processes (such as differentiation, growth, and apoptosis), CLK kinases regulate pre-mRNA splicing through this mechanism, thereby affecting protein translation (Muraki, M. et al. J. Biol. Chem. 2004, 279, 24246-24254).

[0004] Human DYRKs comprise five members, classified into two groups based on their phylogenetic relationships: class I DYRKs, including DYRK1A and DYRK1B; and class II DYRKs, including DYRK2, DYRK3, and DYRK4. DYRK kinases are “dual-specific” kinases because they can phosphorylate both tyrosine (Y) and serine / threonine (S / T) residues, although Y-phosphorylation is limited to their autophosphorylation activity. DYRK kinases phosphorylate a wide range of substrates involved in a broad spectrum of biological processes. Therefore, aberrant regulation or expression of DYRK kinases is associated with a variety of human pathologies, including cancer, ranging from genomic instability to increased proliferation and drug resistance, programmed cell death, or signaling pathways related to tumorigenesis and progression. For example, DYRK1A is a negative regulator of the calcineurin / NFAT signaling pathway. Recent studies have shown that inhibition of DYRK1A can induce β-cell proliferation both in vitro and in vivo. Inhibiting DYRK1A protein expression can promote the activation of the calcineurin / NFAT signaling pathway, thereby promoting β-cell proliferation. DYRK1A also plays an important role in cardiac repair, regulating cardiomyocyte proliferation and promoting cardiac repair after myocardial infarction (Lan, C. et al, eBioMedicine. 2022, 82:104139). DYRK1B is widely involved in tumorigenesis, cell growth and development, and energy metabolism. Activating mutations at DYRK1B site 102 are associated with central obesity, diabetes, and early-onset coronary heart disease.

[0005] Given their crucial roles in the development and progression of disease, the development of CLK and / or DYRK inhibitors is of great significance. Currently, CTX-712 is one reported CLK and DYRK inhibitor, which has shown strong inhibitory effects on splicing-vulnerable cancer cells in preclinical studies. Summary of the Invention

[0006] For the purposes of this invention, this application provides a CLK and / or DYRK inhibitor, which is a compound of formula (Ia), or a pharmaceutically acceptable salt, deuterated derivative, solvate, polymorph, metabolite, or prodrug thereof.

For example, cytochrome P450 catalyzes various oxidation and reduction reactions, while glucuronyl diphosphate transferases catalyze the conversion of activated glucuronic acid molecules to aromatic alcohols, aliphatic alcohols, carboxylic acids, amines, and free sulfhydryl groups. Further information on metabolism can be obtained from *The Pharmacological Basis of Therapeutics*, 9th edition, McGraw-Hill (1996). Metabolites of the compounds disclosed herein can be identified by administering the compound to a host and analyzing tissue samples from that host, or by incubating the compound with hepatocytes in vitro and analyzing the resulting compound. Both methods are known in the art. In some embodiments, the metabolites of the compound are formed through an oxidation process and correspond to the corresponding hydroxyl-containing compounds. In some implementations, the compound is metabolized into a drug-active metabolite.

[0155] The term “modulation” as used in this article refers to direct or indirect interaction with a target to alter its activity, including, for example, enhancing, inhibiting, limiting, or prolonging the activity of a target.

[0156] The term "prodrug" or "prodrug precursor" refers to derivatives that may not be pharmacologically active, but in some cases can be administered orally or parenterally and subsequently metabolized in vivo to form the pharmacologically active compounds of the present invention. Non-limiting examples of prodrugs include esters, carbonates, hemiesters, phosphate esters, nitro esters, sulfate esters, sulfoxides, amides, carbamates, nitrogen-containing compounds, phosphoramides, glycosides, ethers, acetals, and ketoacetates, etc.

[0157] "Effective amount" refers to the amount of a drug or pharmaceutical preparation that will elicit a biological or medical response in an investigational tissue, system, animal, or human, such as that of an investigator or physician. Furthermore, the term "therapeutic effective amount" refers to any amount that, compared to a corresponding subject who has not received that amount, results in a treatment, cure, prevention, or relief of disease, disorder, or side effects, or a reduction in the rate of disease or disorder progression. The term also includes amounts that effectively improve normal physiological function.

[0158] As used herein, the term "treatment" refers to the relief of at least one symptom of a disease, disorder, or condition. This term includes administering medication to a subject and / or applying one or more of the compounds described herein to provide management or treatment of the condition. For the purposes of this disclosure, "treatment" may, but does not necessarily, provide a cure; rather, it means that "treatment" can be a form of management of the condition. When the compounds described herein are used to treat harmful proliferating cells (including cancer), "treatment" includes the partial or complete destruction of said harmful proliferating cells, but with minimal impact on normal cells. The desired treatment mechanism for harmful, rapidly proliferating cells (including cancer cells) is apoptosis at the cellular level.

[0159] As used in this article, “prevention” includes the initiation of joint prevention or mitigation of the development of a clinically significant disease or the initiation of a preclinically significant disease stage in an individual at risk. This includes preventative treatment of individuals at risk of disease development.

[0160] The terms "subject" or "patient" include organisms that may suffer from a condition or a condition associated with reduced or insufficient programmed cell death (apoptosis) or that may otherwise benefit from administration of the compounds of the present invention, such as humans and non-human animals. Preferred humans include human patients who suffer from or are predisposed to suffer from the condition or related condition as described herein. The term "non-human animal" includes vertebrates, such as mammals, such as non-human primates, sheep, cattle, dogs, cats, and rodents such as mice, as well as non-mammals such as chickens, amphibians, reptiles, etc.

[0161] The GI used in this article 50 This refers to the drug concentration required to inhibit the growth of 50% of cells, that is, the drug concentration at which the growth of 50% of cells (such as cancer cells) is inhibited or controlled.

[0162] IC used in this article 50 This refers to the amount, concentration, or dose of a specific test compound that achieves 50% inhibition of the maximum effect in the analysis of the measured effect.

[0163] EC used in this article 50 A dose-dependent response refers to a dose, concentration, or amount of a measured compound that elicits a specific response induced, stimulated, or enhanced by that compound at a maximum expression of 50%.
