Abstract

The invention belongs to the technical field of medicines, and particularly relates to a pharmaceutical composition for preventing and / or treating cancers. The invention relates to a medicine composition, in particular to a medicine composition containing a CDK4 / 6 inhibitor compound shown in a formula (I) or pharmaceutically acceptable salt thereof and a second treatment reagent or pharmaceutically acceptable salt thereof, application of the medicine composition in preparation of medicines for preventing and / or treating cancers and a medicine box containing the medicine composition.

Description

technical field [0001] The present invention belongs to the technical field of medicine, and specifically relates to a pharmaceutical composition for preventing and / or treating cancer, especially a compound containing the compound of formula (I) or a pharmaceutically acceptable salt thereof and a second therapeutic agent or a pharmaceutically acceptable salt thereof. Pharmaceutical compositions of salts, and use of said pharmaceutical compositions for preventing and / or treating cancer. Background technique [0002] The functional effects of almost all oncogenes and tumor suppressor genes will eventually converge on the cell cycle, and regulating or blocking the cell cycle is one of the ways to treat tumors. 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. Among the CDK isoforms involved in the cell cycle, CDK4 / 6 ...
