Description

technical field [0001] The invention provides a nitrogen-containing heterocyclic compound, its preparation method and application. Background technique [0002] Tumor is a kind of cell cycle disease (Cell Cycle Disease, CCD), regulating or blocking cell cycle is one of the ways to treat tumor. At present, many molecules related to cell cycle regulation have been discovered, among which cyclin-dependent kinases (Cyclin-Dependent-Kinases, CDKs) are the core molecules of the cell cycle regulation network. CDKs are catalytic subunits, a class of serine (Ser) / threonine (Thr) kinases, as important signal transduction molecules in cells, and the CDK-cyclin complex formed by cyclin (cyclin), involved in cell growth , proliferation, dormancy and apoptosis. Cell cycle regulatory proteins play an important role in the regulation of cell proliferation. In tumor cells, the abnormality of cyclins and CDKs in G1 phase is the most frequent, and there may be multiple mechanisms involved in...
