Abstract
Description
Tyrosine Kinase Inhibitors and Uses Thereof
[0001] Declaration of Priority
[0002] The present disclosure claims priority to Chinese patent application NO. 2024114953641, filed Oct. 24, 2024, the entire contents of which are incorporated by reference herein in its entirety.Technical Field
[0003] The present disclosure relates to the field of biomedicine, and specifically to tyrosine kinase inhibitors and uses thereof.Background
[0004] Clinical and preclinical evidence demonstrates that TAMs, as key regulatory immune cells, can promote tumor development. Macrophages primarily exist in two polarized states. Alternatively activated M2 subtype TAMs promote tumor progression by secreting anti-inflammatory cytokines (e.g., interleukin (IL) -10, transforming growth factor-β) , whereas activated M1 subtype TAMs enhance immune-mediated tumor killing by producing pro-inflammatory cytokines. To overcome the immunosuppressive and tumor-promoting functions of TAMs, current therapeutic strategies focus on the depletion of TAMs in the tumor microenvironment and the reprogramming of TAMs to promote anti-tumor functions (shifting M2 polarization to M1) . The CSF-1R kinase is a product encoded by the proto-oncogene c-fms and belongs to the class III receptor tyrosine kinase family, which also includes FMS-like tyrosine kinase 3 (FLT3) , stem cell factor receptor (c-Kit) and PDGFR. CSF-1R binds to its ligands, CSF-1 and IL-34, to activate CSF-1R, thereby playing a crucial role in the proliferation, differentiation, and growth of mononuclear phagocytes. In the tumor microenvironment, a large number of macrophages (TAMs) are present, expressing the CSF-1R on their cell surface. When CSF-1 binds to this receptor, macrophages are converted to a pro-tumor state, driving immune suppression and promoting tumor cell growth. Furthermore, high expression of CSF-1R on tumor cells is associated with lower survival rates in certain cancer patients, indicating tumor dependency, making it a potential therapeutic target. By targeting CSF-1R, the development of CSF-1R / CSF-1 inhibitors can effectively reduce the number of TAMs in tumor tissues, promote the generation of anti-tumor macrophages, and help relieve immune suppression. Additionally, it facilitates the infiltration of various immune cells, including T cells and lymphocytes, into the tumor tissue.
[0005] Cancer cell growth and metastasis depend on the formation of neovascularization. Vascular endothelial growth factor (VEGF) is the most potent pro-angiogenic factor because solid tumors depend on angiogenesis to provide oxygen and nutrients to aid in their growth and, in turn, as a pathway for invasion and metastasis. In addition, the VEGFa-VEGFR2 signaling pathway plays an important role in the tumor microenvironment and significantly promotes the proliferation and infiltration of Treg (regulatory T cells) in tumor tissues in animal models. Inhibition of the VEGFa-VEGFR2 signaling pathway can inhibit tumor growth by regulating Tregs, MDSCs, and M2 macrophages. Inhibition of VEGFR2 significantly reduced Treg levels in tumor tissues, further helping to deregulate immunosuppression.
[0006] PDGFR is a transmembrane glycoprotein with tyrosine kinase activity, primarily expressed on mesenchymal-derived cells such as fibroblasts, pericytes, vascular smooth muscle cells, and stromal stem / progenitor cells. PDGFR consists of α and β subunits. Typically, PDGFRα and PDGFRβ exist as monomers in an autoinhibited state. Upon binding with platelet-derived growth factor (PDGF) , PDGFR monomers dimerize, forming isomers PDGFR-αα, PDGFR-αβ, and PDGFR-ββ, which mediate a series of downstream signaling responses. The PDGF / PDGFR primarily promotes angiogenesis and vascular maturation, playing a role in growth and development, and is also closely related to the occurrence and progression of various diseases. Due to the characteristics of tumor microvasculature, such as rapid but immature growth, irregularity, and high permeability, the transport and distribution of chemotherapeutic drugs and oxygen to tumor tissues are hindered, making it easy for tumor cells to metastasize and invade other areas through the leaky vessels. The abnormal vascular system creates a malignant tumor microenvironment characterized by hypoxia, low pH, and elevated interstitial fluid pressure, which interferes with the function of immune cells within the tumor and reduces the efficacy of radiation therapy and chemotherapy. Therefore, the focus of current anti-angiogenic therapy has shifted from simply destroying blood vessels to “normalizing” tumor microvasculature, in order to increase oxygen supply and alter the direction of drug delivery. The root cause of abnormal vascular growth in tumor tissues lies in the disruption of various growth factors within the microenvironment. The PDGF / PDGFR pathway, as a key factor in regulating vascular growth and recruiting pericytes to promote vascular maturation, plays an indispensable role in this process.
[0007] Discoidin domain receptor 1 (DDR1) is a novel receptor tyrosine kinase (RTK) that, upon activation, regulates matrix metalloproteinase (MMP) , epithelial mesenchymal transition (EMT) , and plays an important role in tumor cell migration. Some studies have shown that inhibition of DDR1 expression can induce autophagy and improve the sensitivity of tumor cells to radiation therapy and chemotherapy.
[0008] As is well known, multi-target drugs have obvious advantages over combination drugs and multi-component drugs: due to single component, they are better than combination drugs and multi-component drugs in drug metabolism; they overcome the adverse reactions caused by interactions between components; they are convenient to administer, and there is no problem of dosage or ratio in combination drugs; they have predictable pharmacodynamics (PD) and pharmacokinetic (PK) properties; under the premise of the same therapeutic effect, due to synergistic effect can make the drug dose lower, thus improving the adverse effects of highly selective single-target drugs; slow down the occurrence of drug resistance.
[0009] It is an object of the present disclosure to provide a compound having tyrosine kinase inhibitory activity, which achieves enhanced tumor suppression efficacy through synergistic effects of multi-target inhibition and reduces the occurrence of drug resistance.Summary of the Invention

[0256] The term "prodrug" refers to a compound that is converted in vivo into the parent drug substance. Prodrugs are often used because, under certain circumstances, they may be easier to administer than the parent drug. For example, a prodrug may be bioavailable by oral administration whereas the parent drug is not. A prodrug may also have higher solubility than the parent drug in pharmaceutical compositions. Examples of prodrugs include, but are not limited to, esters of compounds of Formula I (acting as prodrugs) administered to facilitate transport across cell membranes where water solubility is detrimental to mobility, but where, inside the cell, the ester is subsequently metabolically hydrolyzed to the carboxylic acid active substance.
