Abstract
Description
[Technical field]
[0001] The present invention relates to 1,4,5,6-tetrahydropyrimidin-2-amine derivatives and pharmaceutical compositions containing the same, in particular to 1,4,5,6-tetrahydropyrimidin-2-amine derivatives and pharmaceutical compositions containing the same for the prevention, alleviation and / or treatment of diseases associated with integrin αv. [Background technology]
[0002] In recent years, integrins have been attracting attention for their cell adhesion and intracellular signal transduction functions in response to information from the extracellular matrix. Integrins are proteins expressed on the cell surface and are composed of a heterodimer of two subunits, an α chain and a β chain. 24 types of integrins are formed into several subfamilies by combining 18 types of α chains and 8 types of β chains. RGD integrins, one of the major subfamilies, recognize ligands that contain an RGD (arginine-glycine-aspartic acid) motif in the protein sequence. There are eight subtypes of RGD integrins: αvβ1, αvβ3, αvβ5, αvβ6, αvβ8, αIIbβ3, α5β1, and α8β1 (Non-Patent Document 1).
[0003] Integrin αv is known to be involved in various diseases, and its inhibition is expected to be effective in treating, for example, cardiovascular diseases, diabetic diseases, neurodegenerative diseases, cancer diseases, tumor metastasis, eye diseases, autoimmune diseases, bone diseases, and various fibroses (Non-Patent Documents 2 to 6).
[0004] Transforming growth factor β (TGF-β) is known to control cell proliferation and differentiation, and is involved in diseases such as fibrosis, autoimmune diseases, and cancer, and is secreted in an inactive form in a complex with latency-associated protein (LAP) (Non-Patent Document 7). In cell studies, it has been reported that RGD integrins such as integrins αvβ1, αvβ3, αvβ5, αvβ6, and αvβ8 activate latent TGF-β (Non-Patent Documents 8 and 9).
[0005] Fibrosis, a pathological feature of many diseases, is caused by a malfunction of the body's natural ability to repair damaged tissue. Fibrosis can result in excessive scarring that exceeds the wound healing response of vital organs, potentially causing irreparable damage and eventual organ failure (Non-Patent Document 10). In fibrosis, extracellular matrix is primarily produced by activated fibroblasts (myofibroblasts), and it is known that TGF-β is involved in the activation of these fibroblasts (Non-Patent Document 11).
[0006] Integrin expression is also involved in fibrosis; for example, the expression levels of integrin β5 and β6 are significantly increased after tissue injury and play an important role in tissue fibrosis in vivo (Non-Patent Documents 12 and 13). Increased expression levels of integrin β6 are also associated with increased mortality in fibrosis patients (Non-Patent Document 14).
[0007] Inhibition of integrins is known to confer resistance to various fibrotic diseases. For example, integrin β6 knockout mice inhibit TGF-β activation and are resistant to various fibrotic diseases (Non-Patent Documents 15 and 16). It has also been reported that fibroblast-specific deletion of integrin αv similarly confer resistance to various fibrotic diseases (Non-Patent Documents 17 and 18).
[0008] For example, pirfenidone and nintedanib are used as therapeutic agents for fibrosis in idiopathic pulmonary fibrosis (IPF), but no safe and established therapeutic agent has yet been found for fibrosis in various organs. Therefore, there is a need for a therapeutic agent for fibrosis that has minimal side effects and is effective for various organs.
[0009] Research has been conducted on integrins involved in the control of various cell functions and their inhibitors (Patent Documents 1 to 8, Non-Patent Document 19). [Prior art documents] [Patent documents]

[0100] The compounds of the present invention represented by the general formula (I) or (II) or pharma- ceutical acceptable salts thereof can inhibit the binding of integrin αv to its ligand. In another embodiment, the compound represented by the general formula (I) or (II) of the present invention or a pharma- ceutical acceptable salt thereof can inhibit the activation of TGF-β. TGF-β is involved in cell differentiation, survival, proliferation, etc., and plays an important role in development, immunity, wound healing, etc., and is therefore deeply involved in diseases such as inflammation, fibrosis, and cancer. Three types of isoforms of TGF-β are known in mammals, and TGF-β1 is known as a master regulator of tissue repair, inflammation, and fibrosis (Seminars in Cell and Developmental Biology, 2020,101,123-139.). TGF-β is secreted as an inactive (latent) form and is activated in various ways to exhibit physiological activity. It is known that RGD integrins including αvβ1 and αvβ6 play an important role in the activation of TGF-β1, and for example, αvβ1 integrin inhibitors (Non-Patent Document 8: Science Translational Medicine, 2015,7(288),288ra79.) and αvβ6 integrin inhibitors (Cancer Research,2008,68(2),561-570.) inhibit the activation of TGF-β1. Therefore, the compound represented by the general formula (I) or (II) of the present invention or a pharmacologic acceptable salt thereof may be useful for the prevention, alleviation and / or treatment of diseases such as inflammatory diseases, fibrosis, cancer, neurodegenerative diseases, eye diseases, osteoporosis and osteogenesis imperfecta. In another embodiment, the compound represented by the general formula (I) or (II) of the present invention or a pharma- ceutical acceptable salt thereof can induce dedifferentiation of activated human hepatic stellate cells. Stellate cells and fibroblasts are differentiated into activated stellate cells and myofibroblasts expressing α-smooth muscle actin (α-SMA, ACTA2) by TGF-β1 and the like, and enhance collagen production and the like. For example, it has been reported that in stellate cells in which integrin αv is knocked out, TGF-β1 is not activated, so that the expression of α-SMA is suppressed, and further the production of collagen and the like is also suppressed (Non-Patent Document 16: Nature Medicine, 2013, 19(12), 1617-1624.). Such enhanced collagen production is seen in diseases such as inflammation, fibrosis, and cancer. Therefore, the compound represented by general formula (I) or (II) of the present invention or a pharma- ceutical acceptable salt thereof may be useful for the prevention, alleviation and / or treatment of diseases such as inflammatory diseases, fibrosis, cancer, neurodegenerative diseases, eye diseases, osteoporosis and osteogenesis imperfecta.
