Abstract
The application relates to a novel Bruton's tyrosine kinase inhibitor, which is a compound containing a polyaromatic heterocyclic structure, comprising a compound shown in a formula (I) or an isomer, a stable isotope derivative, a hydrate, a solvate, a polymorph and a pharmaceutically acceptable salt thereof, and also discloses a preparation method of the compound and a method for using the novel compound to treat or prevent Bruton's tyrosine kinase related diseases such as Acute Lymphoblastic Leukemia (ALL), chronic granulocytic leukemia (CML), mantle Cell Lymphoma (MCL), colorectal cancer, rheumatoid arthritis, organ transplantation rejection resistance, psoriasis resistance, lupus erythematosus and the like.
Description
Technical Field
The application belongs to the field of drug synthesis, and particularly relates to a novel Bruton's tyrosine kinase inhibitor, and a preparation method and application thereof.
Background
Bruton's tyrosine kinase is a member of the Tec family of non-receptor protein tyrosine kinases. The Tec family is the 2 nd largest family of human non-receptor kinases next to the Src family, the major members of which include Bruton's tyrosine kinase, BMX (etk), ITK, tec, and TXK (PLK). Bruton's tyrosine kinase was identified in 1993 as a defective protein in human X-linked agaropectinemia (X-linked agammaglobulinemia, XLA). This protein is expressed at various stages of B cell development (except for terminally differentiated plasma cells), and Bruton's tyrosine kinase is an essential gene for cell differentiation and proliferation during the transition from pre-B lymphocytes to post-B cells, and is expressed in B cell lymphomas, acute Lymphoblastic Leukemia (ALL) and plasmacytomas. In addition, there is also a small expression in bone marrow cells and erythroid progenitors.
Currently, small molecule inhibitors of Bruton's tyrosine kinase such as ibrutinib (ibrutinib), acartinib (acalabrutinib), and zebutinib (zaubrutinib) are approved by the FDA in the united states for the treatment of Mantle Cell Lymphoma (MCL) and CLL.
Although ibrutinib, acartinib and zebutinib are therapeutically effective, a significant proportion of clinical B-cell lymphoma patients are not susceptible to their treatment, except for a proportion of patients who develop resistance later, such as approximately 1/3 of the patients in MCL do not respond to their treatment, nor do the response rates in DLBCL. In view of the above, there remains a need in the art to develop highly active, specific inhibitors of Bruton's tyrosine kinase.
Disclosure of Invention
In order to solve the problems, the application provides a novel compound of Bruton's tyrosine kinase inhibitor shown in a formula (I) or a stereoisomer, a stable isotope derivative, a hydrate, a solvate and a pharmaceutically acceptable salt thereof:

The results of the assay are shown in the following table, showing the activity data of compounds 1-28 for wild-type BTK, mutant BTK (R28H). Active utilization IC 50 Characterization, wherein "A" represents IC 50 Less than or equal to 10nM; "B" means 10<IC 50 Less than or equal to 100nM; "C" means 100<IC 50 Less than or equal to 500nM; "D" means 500<IC 50 ≤2000nM。
