Problems solved by technology

However, during the course of administration, ibrutinib is easily metabolized (oxidatively metabolized into dihydroxylated products by metabolic enzymes or attacked and inactivated by other sulfhydryl-containing enzymes, cysteine, glutathione, etc. ) and affect the drug efficacy (see the following formula), its clinical dosage has reached 560mg / day, which increases the burden on patients, so it is still necessary to develop a class of more efficient BTK inhibitors for the treatment of related diseases

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a double-site irreversible Bruton's tyrosine kinase inhibitor, a pharmaceutical composition containing it and its application in antitumor. Background technique [0002] Small molecule covalent inhibitors, also known as irreversible inhibitors, are a class of inhibitors that irreversibly bind to target protein residues through covalent bonds to exert their biological functions. Covalent inhibitor drugs have made important contributions to human health over the past few decades. Compared with non-covalent inhibitors, covalent inhibitors enhance the affinity with the target by covalently binding with the target protein, which is the fundamental reason for the high biological activity of covalent inhibitors. In recent years, more attention has been paid to covalent inhibitors due to the emergence of resistance to non-covalent targeting antineoplastic drugs, especially a large number of tini...
