Description:
FIELD OF INVENTION 
       [0001]    The present invention relates to a fused pyrimidine compound, and preparation method, intermediate, composition, and uses thereof. 
       PRIOR ART 
       [0002]    Phosphoinositide 3-kinase (PI3K) is a type of intracellular phosphatidylinositol kinase that can catalyze the phosphorylation of the 3-hydroxy of phosphatidylinositol. The PI3K family can be divided into three classes (I, II, and III), and the most extensively investigated one is the class I PI3Ks that can be activated by cell surface receptors. Class I PI3Ks in mammalian cells are further divided into two groups based on their structures and receptors, class Ia and class Ib, which transmits signals from tyrosine kinase-coupled receptors and G protein-coupled receptors, respectively. Class Ia PI3Ks are further divided into PI3Kα, PI3Kβ and PI3Kδ ( Trends Biochem. Sci.,  1997, 22, 267-272). Class Ia PI3Ks are dimers of a catalytic subunit, p110, and a regulatory subunit, p85, having dual activity of lipid kinases and protein kinases ( Nat. Rev. Cancer  2002, 2, 489-501). PI3K can be activated in two ways, one is through the interaction with growth factor receptors or coupled proteins having phosphorylated tyrosine residues, inducing a conformational change of the dimer; the other is through the direct binding of Ras to p110, thereby inducing the activity of PI3K ( Curr. Opin. Pharmacol.,  2003, 3, 426-434). The activation of PI3K generates a second messenger PIP3 at the plasma membrane. The binding of PIP3 to intracellular signaling proteins containing a PH domain, Akt and PDK1 (phosphoinositide-dependent kinase-1), causes the phosphorylation of Ser308 of Akt protein by PDK1, which is responsible for activating Akt. Akt can also be activated by phosphorylating its Thr473 by PDK2 (such as integrin-linked kinase, ILK) ( Cancer. Res.,  2003, 63, 2139-2144). Activated Akt activates or inhibits its downstream target proteins such as mTor, Bad, Caspase9, NF-kB, GSK-3, FKHR and MDM2, etc. by phosphorylation, thereby regulates cell proliferation, differentiation, apoptosis and migration ( Annu. Rev. Cell Dev. Biol.,  2011, 17, 615-675). Studies have shown that over-activation of PI3K is closely related to human malignancies such as breast cancer, lung cancer, melanoma and lymphoma, etc. ( Leukemia,  2003, 17, 590-603). 
         [0003]    Further, since the mammalian target of rapamycin (mTOR) is the main effector of PI3K signal pathway, it can partially mediate and phosphorylate proto-oncogene Akt/PKB. Recent studies show that the inhibition of PI3Kα is essential to the inhibition of the growth of malignant cells ( Science,  1997, 276, 1848-1850). PI3K is an upstream molecular of Akt/mTOR pathway, its abnormal activation may cause a series of reactions including the growth, proliferation and motility of cells, the change from epithelial cells to mesenchymal cells, and angiogenesis. Thus, PI3K inhibitors can inhibit tumor cell proliferation, induce tumor cell apoptosis and reverse drug resistance of tumor cells. There is evidence that inhibiting both PI3K and mTOR may have synergistic inhibition for tumor growth ( Cancer Res.,  67, 7960-7965). Thus, PI3K/mTOR dual inhibitors may be the future direction of development of tumor targeted therapy. 
         [0004]    Existing technologies have disclosed a number of compounds as PI3K inhibitors, such as: WO2008064093, WO2007044729, WO2008127594, WO2007127183, WO2007129161, US20040266780, WO2007072163, WO2009147187, WO2009147190, WO2010120987, WO2010120994, WO2010091808, etc. 
         [0005]    So far there is no small molecular PI3K inhibitor in market. The object of the present invention is to provide an efficient, low toxicity medicine of PI3K inhibitor for the treatment of cell proliferation diseases such as cancer, infections, inflammation and autoimmune diseases.

         [0080]    The term “alkylthio” refers to a cyclic or non-cyclic alkyl group containing the indicated number of carbon atoms and having a connection through a sulfur atom. Thus, “alkylthio” includes the definition of “alkyl” and “cycloalkyl”. 
         [0081]    The term “halogen” refers to fluorine, chlorine, bromine, iodine, or astatine. 
         [0082]    The term “haloalkyl” refers to an alkyl group substituted by halogen at optionally position. Thus, “haloalkyl” includes the definition of“halogen” and “alkyl”. 
         [0083]    The term “haloalkoxy” refers to an alkoxy group substituted by halogen at optionally position. Thus, the “haloalkoxy” includes the definition of “halogen” and “alkoxy”. 
         [0084]    The term “aryloxy” refers to an aryl group containing the indicated number of carbon atoms and having a connection through an oxygen bridge. Thus, “aryloxy” includes the definition of“aryl”. 
         [0085]    As used herein, the term “arylhetero” or “heteroaryl” refers to any stable monocyclic or bicyclic ring containing up to 7 atoms in each ring, wherein at least one ring is an aromatic ring containing 1 to 4 heteroatoms selected from the group consisting of O, N, and S. Heteroaryl groups within the scope of this definition include, but are not limited to, acridinyl, carbazolyl, cinnolinyl, quinoxalinyl, pyrazolyl, indolyl, benzotriazolyl, furyl, thienyl, benzothienyl, benzofuranyl, quinolinyl, isoquinolinyl, oxazolyl, isoxazolyl, indolyl, pyrazinyl, pyridazinyl, pyridinyl, pyrimidinyl, pyrrolyl, tetrahydroquinolinyl. As the heterocycle defined below, “heteroaryl” should also be understood to include the N-oxide derivative of any nitrogen-containing heteroaromatic group. It can be understood that if a heteroaryl substituent is a bicyclic ring having one non-aromatic ring or one ring without heteroatom, then the connection is through the aromatic ring or the heteroatom containing in the ring. Heteroaryl groups are optionally substituted by 1 to 4 substituents selected from the group consisting of deuterium, halogen, alkyl, alkoxy, hydroxyl, aryl, aryloxy, arylalkyl, cycloalkyl, alkylamino, acylamino, acyl, arylcarbonylamino, amino, nitro, cyano, thiol and/or alkylthio and/or any alkyl substituents. 
         [0086]    As used herein, the term “heterocycle” or “heterocyclyl” refers to 5 to 10 membered aromatic or non-aromatic heterocyclic ring having 1 to 4 heteroatoms selected from the group consisting of O, N, and S, bicyclic groups are also included.

         [0087]    The term “heteroalicyclyl” or “heterocycloalkyl” used herein alone or as a part of other groups refers to a 4 to 12 membered saturated or partially unsaturated ring containing 1 to 4 heteroatoms (such as nitrogen, oxygen and/or sulphur). The heterocycloalkyl groups may include 1 to 4 substituents, such as alkyl, halogen, oxo and/or any alkyl substituents set out above. In addition, any heterocycloalkyl rings can be fused to a cycloalkyl, aryl, heteroaryl or heterocycloalkyl ring, and to form a fused ring or a spiro ring. A heterocycloalkyl substituent can be linked with other groups through a carbon atom or a heteroatom.

For example: R 5  may be hydrogen, a C 1-12  alkyl, a C 2-8  alkenyl, a C 2-8  alkynyl, a C 3-12  carbocyclyl, a C 2-20  heterocyclyl, a C 6-20  aryl or a C 1-20  heteroaryl. When R 2  is —(CR 8 R 9 ) m NR 5 R 6 , R 4  is —NR 5 R 6  and the R 5  in R 2  is —CF 3  or halogen (within the scope of the definition of R 5 ), the R 5  in R 4  can be —CF 3  or halogen, and can also be a C 1-12  alkyl (all within the scope of the definition of R 5 ).

         [0324]    Biological Effect Example 2 Cell Proliferation Inhibition Assay 
         [0325]    Cancer cell lines (A549, PC3, or U97-MG) in the logarithmic growth phase were plated at a density of about 3,000 per well in 96-well plates, 90 μL/well, using double wells for each concentration. Control wells containing corresponding concentration of vehicle and without cells were also prepared. After 24 hrs, positive control compound and example compounds were added to make 10 μL/well and final DMSO concentration of 0.5%. The cells were incubated with compounds for 72 hrs in the presence of 10% Invitrogen fetal bovine serum, 37° C., 5% CO 2 . 5 mg/mL MTT solution was added to make 10 μL/well, and incubated for 4 hours at 37° C. A ddH 2 O solution (10% SDS, 5% isobutanol, 10 mmol/L HCl) was added to make 100 μL/well and incubated overnight at 37° C. OD values were measured using microplate reader under 580 nm and 680 nm, and the IC 50  values of the example compounds for cancer cells were calculated. Experimental data are shown in Table 2:

         [0327]    Biological Effect Example 3 Growth Inhibition Effects of Compounds to Malignant Glioma Cell U87MG Xenograft in Nude Mice 
         [0328]    Groups of nude mice were implanted subcutaneously in the right hind back with 4×10 6  U87MG cells. Start dosing when mean tumor volume reached approximately 150 (100-200) mm 3 . Grouping method: before dosing, animals were weighted, tumor sizes were measured, and randomized according to the tumor size (randomized block design), 8 mice per group. A solvent (0.5% CMC-Na+0.2% Tween-80) was dosed once daily by oral gavage for solvent control group, and pre-determined dose of test compound was dosed once daily by oral gavage for a dosing group, for 20 consecutive days. 
         [0329]    Tumor diameters were measured twice a week with a vernier caliper. Tumor volume was calculated with formula: V=0.5a×b 2 , a and b represent longer and shorter diameter of tumor. Antitumor efficacy of the test compound was evaluated with TGI (%) reflecting tumor growth inhibition rates, which is calculated as follows: TGI (%)=[1−(tumor volume of treating group at the end of dosing period—tumor volume of treating group in the beginin of dosing)/(tumor volume of vehicle group at the end of dosing period−tumor volume of vehicle group in the beginin of dosing)]×100%. Meanwhile, the weight of nude mice in each group was weighed twice weekly for a preliminary evaluation of compound toxicity. Experimental data are shown in Table 3.
