Abstract

The invention belongs to the technical field of medicines and particularly relates to a CDK kinase inhibitor represented as the general formula (I), pharmaceutically-accepatable salt, ester and solvate thereof, and stereisomers thereof. The R1, R2, R3, R4, A1, A2, A3 and n are defined as the specification. The invention also relates to a preparation method of the compounds, a medicine preparation and a medicine composition comprising the compounds, and an application of the compounds, the pharmaceutically accepatable salt, ester and solvate thereof, and the stereisomers thereof in preparation of a medicine for treating and / or preventing cancer-related diseases induced by the CDK kinase.

Description

technical field [0001] The present invention belongs to the technical field of medicine, and specifically relates to CDK kinase inhibitors, their pharmaceutically acceptable salts, their esters, their solvates and their stereoisomers, pharmaceutical preparations and pharmaceutical compositions containing these compounds, and the compound , its pharmaceutically acceptable salts, its esters, its solvates and their stereoisomers, in the preparation of medicines for treating and / or preventing cancer-related diseases mediated by CDK kinases. Background technique [0002] Tumor occurrence is related to the imbalance of various oncogenes and tumor suppressor genes. The functional effects of almost all oncogenes and tumor suppressor genes will eventually converge on the cell cycle. Therefore, it can be said that tumors are a type of cell cycle disease (Cell Cycle Disease, CCD), and regulating or blocking the cell cycle is one of the ways to treat tumors. At present, many molecules...
