Abstract

The invention belongs to the technical field of medicine, particularly relates to a heterocyclic nitrogen compound which acts as a tyrosine kinase inhibitor and is represented by a general formula (I) as well as a deuterated material, pharmaceutically acceptable salt or stereisomer thereof. In the general formula (I), X, W, R1, R2, R3, L1, L2, a, b, c, d, e, p, q, a ring A and a ring B are defined in specification. The invention further relates to a preparation method of the compounds, a pharmaceutic preparation containing the compounds, and important actions of the compounds in treatment of leukemia (such as B cell chronic lymphocytic carcinoma and non-hodgkin lymphoma) related to B cell, and autoimmune diseases (such as rheumatoid arthritis and systemic lupus erythematosus).

Description

1. Technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a nitrogen-containing acyclic compound as a tyrosine kinase inhibitor, its deuterated substance, its pharmaceutically acceptable salt or its stereoisomer, and the preparation method of the compound comprises The pharmaceutical preparation of the compound, and the compound is used in the preparation and treatment of blood cancers related to B cells (such as B cell chronic lymphocytic carcinoma, non-Hodgkin's lymphoma), and autoimmune diseases (such as rheumatoid arthritis, systemic Lupus erythematosus, etc.) plays an important role. 2. Background technology [0002] Protein kinases constitute one of the largest families of human enzymes and regulate many different signaling processes by adding phosphate groups to proteins (T. Hunter, Cell 198 750:823-829). In particular, tyrosine kinases phosphorylate the phenolic moieties of proteins at tyrosine residues. The tyr...
