The present invention is related to: a compound that has inhibitory activity of phosphatidylinositol-3-kinase (hereinafter also referred to as “PI3K”) and is useful for the treatment/prevention of a variety of phosphatidylinositol-3-kinase dependent diseases including cancers, inflammatory diseases, circulatory diseases, and the like; a salt thereof; or the like.
Phosphatidylinositol-3-kinase is an enzyme that catalyzes not only the production of a specific phospholipase, but also an intracellular mediator from phosphatidylinositol (hereinafter also referred to as “PI”) of a membrane lipid. The 3′-OH group of phosphatidylinositol is phosphorylated, and thus, when phosphatidylinositol, phosphatidylinositol 4-phosphate, and phosphatidylinositol 4,5-bisphosphate are used as substrates, phosphatidylinositol 3-phosphate, phosphatidylinositol 3,4-bisphosphate, and phosphatidylinositol 3,4,5-triphosphate (PIP3) are produced respectively.
A phospholipid (PIP3) in which the hydroxyl group at 3-position of the inositol ring is phosphorylated by this PI3K works as a second messenger that activates a serine/threonine kinase such as PDK1, Akt/PKB, and the like in a signal transduction route mediated by receptor stimulation. This second messenger is said to regulate many biological processes including growth, differentiation, survival, proliferation, migration and metabolism, and the like of cells.
PI3Ks are classified into three groups, i.e., Classes I to III, by a primary structure, a regulatory mechanism of activity, and specificity to a substrate. Among them, Class I is important in signaling.
Class I is, depending on the differences in the heterodimer, classified into IA (α, β, and δ) containing a subunit of 85 kDa, and IB (γ) containing a subunit of 101 kDa.
Class IA is associated with a variety of cell surface receptors such as hormones/growth factors and the like. For a signal transduction route, it is said to be a protein/kinase receptor type. Class IB is associated with a G protein receptor (GCPR), which is a receptor of a chemokine and the like. Furthermore, it is said that when a specific tyrosine residue of a receptor is phosphorylated by stimulation of an activator such as a chemokine and the like, a regulatory subunit is bound to a catalytic subunit via the SH2 domain, and thereby the inhibition activity of the regulatory subunit is reduced to exhibit enzyme activity.
PIP3 works as a messenger for intracellular signaling. In the immediate downstream of PIP3, AKT (also known as protein kinase B (PKB)) and the like are known. In these downstream routes, a signal is said to be transmitted by activating a functional protein having the PH domain.
PI3Kα and PI3Kβ are widely distributed in a variety of cells, and related to cell growth/glycometabolism. Based on these actions, inhibitors of PI3Kα and PI3Kβ are utilized as anticancer agents and the like. PI3Kδ and PI3Kγ exist mainly in blood and cells of the immune (lymphatic) system. PI3Kγ is also known to be widely distributed in inflammatory cells.
Regarding PI3Kγ, on the basis of studies of knock-out mice thereof and the like, it was found that respiratory burst of a neutrophil by a chemotactic factor and the migration of a macrophage/neutrophil to an infection focus were blocked, functions of T cells/dendritic cells were thereby decreased, the degranulation of mast cells was thereby blocked, and anaphylaxis was thereby decreased. Accordingly, an inhibitor of PI3Kγ is considered useful as a therapeutic agent for these diseases. Furthermore, on the basis of studies of arthritis, it is considered useful as an inhibitor of the inflammatory-cell infiltration in a part of a joint (Non-Patent Literature 1 and Non-Patent Literature 2). Furthermore, studies using a PI3Kγ inhibitor report the inhibition of the activation of a mast cell (Non-Patent Literature 3), the inhibition of the activation/migration of a leukocyte (Non-Patent Literature 4 and Non-Patent Literature 5), the inhibition of lymphocyte activation (Non-Patent Literature 6), and the like.
On the basis of these studies, a PI3Kγ inhibitor is believed to be useful for the treatment of the following diseases/disorders: thrombus; allergy/anaphylaxis (allergic diseases include, for example, asthma, atopic dermatitis, allergic rhinitis, and the like); inflammation such as pancreatitis (Non-Patent Literature 7), pneumonia, airway inflammation, chronic obstructive pulmonary disease (COPD) (Non-Patent Literature 8 and Non-Patent Literature 9), arthritis (e.g., articular rheumatism (Non-Patent Literature 8 and Non-Patent Literature 9), glomerulonephritis, and the like; systemic lupus erythematosus (SLE) (Non-Patent Literature 8 and Non-Patent Literature 9); autoimmune diseases; pulmonary disorder; circulatory diseases such as heart failure (systolic), cardiac ischemia (systolic), high blood pressure, and the like (Non-Patent Literature 10); wound healing; infectious diseases (Non-Patent Literature 11); cancer/tumors such as neoplasm (Patent Literature 1); suppression of the immune reaction in organ transplantation and autoimmune diseases (Patent Literature 2); and the like.
Regarding PI3Kδ, on the basis of studies of knock-out mice thereof and the like, the B cell differentiation disorder of bone marrow is induced, and in immunomodulation, the role thereof is expected.
PI3K is reported to be deeply involved with various stages of diseases in articular rheumatism, such as: the T cell/B cell activation by presenting an antigen; and the inflammatory cell infiltration such as neutrophil, macrophage, or the like, the synovial cell proliferation, the mast cell activation, and the like (Non-Patent Literature 12).
As examples of compounds having PI3 kinase inhibition activity, classically, wortmannin (Non-Patent Literature 13), 2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one (Patent Literature 2), 17β-hydroxywortmannin and a derivative thereof (Patent Literature 1), and the like are known.
As substituted 2-amino-5,6-nitrogenated fused ring compounds being useful as a medicament, compounds disclosed in Patent Literature 3, Patent Literature 4, Patent Literature 5, Non-Patent Literature 14, Non-Patent Literature 15, Non-Patent Literature 16, Patent Literature 6, Patent Literature 7, Patent Literature 8, Patent Literature 9, Patent Literature 10, Non-Patent Literature 17, Patent Literature 11, Non-Patent Literature 18, Non-Patent Literature 19, Patent Literature 12, Patent Literature 13, Patent Literature 14, or the like are known.
The purpose of the present invention is to provide a substituted 2-amino-5,6-nitrogenated fused ring compound or a pharmaceutically acceptable salt thereof, wherein the compound inhibits the activity of PI3K to regulate many biological processes including growth, differentiation, survival, proliferation, migration, and metabolism, and the like of cells, and is therefore useful for the prevention/treatment of diseases including inflammatory diseases (allergic diseases (allergic dermatitis/allergic rhinitis, and the like), articular rheumatism, anaphylaxis, and the like), arteriosclerosis, vascular/circulatory diseases, cancer/tumors, immune system diseases, cell-proliferative diseases, infectious diseases, and the like.

After a subject compound was reacted for a certain time using a pooled human liver microsome commercially available, a reacted sample and an unreacted sample are compared to calculate a survival ratio, and then the degree of metabolism in the liver was evaluated.
0.2 mL of a buffer solution (50 mmol/L of Tris-HCl in pH 7.4, 150 mmol/L of potassium chloride, and 10 mmol/L of magnesium chloride) containing a human liver microsome of 0.5 mg protein/mL was reacted in the presence of 1 mmol/L NADPH at 37 degrees Celsius for 0 or 30 minutes (oxidative reaction). After reacting, 50 μL of the reaction solution was added to 100 μL of a solution of methanol/acetonitrile (1/1(v/v)), mixed, and then centrifuged at 3000 rpm for 15 minutes. A test compound in the supernatant was quantitated with LC/MS/MS. An amount of the compound remained at a reaction time of 0 minute was defined as 100%, and, based on that, an amount of the test compound remained after the reaction was calculated.

For the purpose of a risk evaluation of QT interval extension of electrocardiogram, using the HEK293 cell that was made express human ether-a-go-go related gene (hERG) channel, the activity on delayed rectification K+ current (IKr) playing an important role in a cardiac ventricle repolarization process was examined.
Using an automatic patch-clamp system (PatchXpress 7000A, Axon Instruments Inc.), by a whole-cell patch-clamp method, after the cell was maintained at a membrane potential of −80 mV, IKr induced on giving depolarizing stimulation of +50 mV for 2 seconds and further repolarizing stimulation of −50 mV for 2 seconds was recorded. After generated current became stable, extracellular fluid (NaCl: 137 mmol/L, KCl: 4 mmol/L, CaCl2.2H2O: 1.8 mmol/L, MgCl2.6H2O: 1 mmol/L, glucose: 10 mmol/L, HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid): 10 mmol/L, pH=7.4) dissolving a test substance at an intended concentration was applied to the cell for 10 minutes under room temperature condition. From the IKr obtained, using an analysis soft (DataXpress ver. 1, Molecular Devices Corporation), a current value in a membrane potential maintained was used as a standard, and the absolute value of the maximum tail current was measured. Moreover, an inhibition ratio for the maximum tail current prior to the application of the test substance was calculated, and then compared with a group of media-application (0.1% dimethylsulfoxide solution) to evaluate influence of the test substance on IKr.
