Abstract
Description
technical field
[0001] Certain agents that inhibit Bruton's tyrosine kinase (Btk), and methods of making and using such agents are provided. prior art
[0002] Protein kinases are a large multigene family of more than 500 proteins that play key roles in the development and treatment of many human diseases in oncology, neurology and immunology. Tec kinase is a non-receptor tyrosine kinase composed of five members (Tec (tyrosine kinase expressed in hepatocellular carcinoma), Btk (Bruton's tyrosine kinase), Itk (interleukin 2 (IL-2) inducible T-cell kinase; also known as Emt or Tsk), Rlk (resting lymphocyte kinase; also known as Txk), and Bmx (myeloid tyrosine kinase gene on chromosome X; also known as Etk )) and is mainly expressed in hematopoietic cells, although expression of Bmx and Tec has been detected in endothelial cells and hepatocytes. Tec kinases (Itk, Rlk and Tec) are expressed in T cells and all are activated downstream of the T cell receptor (TCR). Btk is the downstream mediator of B cell receptor (BCR) signal transduction, which is involved in the regulation of B cell activation, proliferation and differentiation. More specifically, Btk contains a PH domain that binds phosphatidylinositol (3,4,5)-triphosphate (PIP3). PIP3 binding induces Btk to phosphorylate phospholipase C (PLCy), which in turn hydrolyzes PIP2 to generate two secondary messengers, inositol triphosphate (IP3) and diacylglycerol (DAG), both of which activate the protein kinase PKC, followed by Induces additional B cell signaling. Mutations that disable Btk's enzymatic activity lead to XLA syndrome (X-linked agammaglobulinemia), a primary immunodeficiency. Given their critical roles in both B-cell and T-cell signaling, Tec kinases are targets of interest in autoimmune disorders.
[0003] Therefore, there is a great need in the art for effective Btk inhibitors. Contents of the invention

To this mixture was added a batch of 4-chloro-6-(1-methylpyrazol-4-yl)pyrazolo[1,5-a]pyrazine (240 mg, 1.03 mmol), and the mixture immediately became Orange brown. Stirring was continued overnight at room temperature. The mixture was diluted with EtOAc, followed by careful addition of water. The mixture was transferred to a separatory funnel and the phases were separated. The aqueous phase was extracted again with EtOAc, and the combined organic phases were washed with brine, dried over Na 2 SO 4 , filtered and evaporated in vacuo.

After 5 min, acryloyl chloride (0.05 mL, 615 μmol) was carefully added dropwise to the cold homogeneous solution. After the acryloyl chloride addition was complete, the reaction was allowed to warm to 23 °C and monitored by LCMS and TLC. After 3 min, the reaction was carefully quenched by the slow addition of saturated aqueous sodium bicarbonate. The mixture was stirred at 23 °C for 1 h, then the biphasic mixture was extracted three times with ethyl acetate. The organics were pooled and washed once with saturated aqueous sodium bicarbonate.
