Description
Technical Field
The invention relates to the field of organic compound synthesis and medical application, in particular to a1, 3, 4-trisubstituted pyrazolopyrimidine compound and a preparation method and pharmaceutical application thereof.
Background
BTK belongs to the Tec family of non-receptor tyrosine kinases, consisting of 659 amino acids, comprising 5 domains, from the amino terminus a PH domain (pleckstrin homology domain), a TH domain (Tec homology domain), a SH 3domain (Src homology 3domain), a SH 2domain (Src homology 2domain) and a catalytic domain (tyrosine kinase domain, also known as SH1 domain), respectively. (see Kawakami Y, Kitaura J, Hata D, Yao L, Kawakami T: Functions of Bruton's tyrosinase in mass and B cells. J Leukoc Biol 1999,65(3): 286) -290.) wherein the PH domain is the key domain for BTK to participate in extracellular stimulation, recognize and bind PIP 3; the TH domain comprises the BTK motif and a proline-rich conserved region; the SH3 structural domain comprises an autophosphorylation site Tyr223, can specifically recognize proline-rich fragments in the TH structural domain, and induces intramolecular folding; the SH 2domain recognizes phosphorylated tyrosine residues with a specific peptide sequence; the catalytic domain is a hinge-linked double-leaf structure, in which the N-leaf end (amino acid residue 394-474) consists of 5 beta sheets and an alpha helix; the C-lobe terminal (amino acid residue 481-659) consists of 8 alpha helices and 1 beta sheet, and contains an activation loop; the hinge domain (amino acid residue 475-480) is the ATP-binding domain. The catalytic domain and the SH 3domain respectively have a tyrosine phosphorylation site, and activated Src family kinase can phosphorylate Tyr551 of the catalytic domain, induce Tyr223 of the SH 3domain to autophosphorylate, and enable BTK to be in an activated state. (see Satterhwaite AB, Li Z, Witte ON: Btk function in B cell resolution and response. Semin Immunol 1998,10(4): 309-316). BTK is over-expressed in B cell malignant tumor cells, and the research on BTK inhibitors has important significance for treating B cell malignant tumors.
