Summary:The present invention discloses a pyrimido- or pyridopyridone compound as shown in formula (I) and an application thereof relating to the technical field of medicament preparation. The compound can selectively suppress cyclin-dependent kinases (Cdks) CDK4 and CDK6 with almost no suppression of the activity of the kinase CDK2. Thus, the compound can be used for various diseases caused by cell cycle control disorders involving CDK4 and CDK6, and particularly in the treatment of malignant tumors. ( see formula I) La présente invention concerne un composé de pyrimidine ou de pyridopyridone tel que représenté dans la formule (I) et une application correspondante, concernant le domaine technique de préparation de médicaments. Le composé peut supprimer de manière sélective les kinases cycline-dépendantes (CDK) CDK4 et CDK6 quasiment sans suppression de l'activité de la kinase CDK2. Ainsi, le composé peut être utilisé pour diverses maladies provoquées par des troubles de régulation du cycle cellulaire impliquant CDK4 et CDK6 et particulièrement dans le traitement de tumeurs malignes.
