Abstract

The invention belongs to the field of medical chemistry and particularly relates to a tricyclic compound, a preparation method thereof and application thereof as a reference substance in qualitative and / or quantitative analysis of related impurities in the research of the quality of a raw material drug of N-(2-((2-(dimethylamino)ethyl)(methyl)amino)-4-methoxy-5-((4-(6,7,8,9-tetrahydropyrido [1,2-a] indol-10-yl) pyrimidine-2-yl) amino) phenyl)allylamide methanesulfonate.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and in particular relates to tricyclic compounds, their preparation methods and their use as reference substances for N-(2-((2-(dimethylamino)ethyl)(methyl)amino) -4-methoxy-5-((4-(6,7,8,9-tetrahydropyrido[1,2-a]indol-10-yl)pyrimidin-2-yl)amino)phenyl ) The use of qualitative and / or quantitative analysis of relevant impurities in the quality research of acrylamide methanesulfonate raw materials. Background technique [0002] Epidermal growth factor receptor (EGFR) is a transmembrane protein tyrosine kinase member of the erbB receptor family. Homodimerization and / or heterodimerization of the erbB receptor leads to phosphorylation of key tyrosine residues in the intracellular domain, stimulating many intracellular signaling pathways involved in cell proliferation and survival. Dysregulation of erbB family signaling promotes proliferation, invasion, metastasis, angiogenesis, and tumor cell survi...
