Compounds represented by general formula (I), (wherein Ar represents a nitrogenous heterocyclic aromatic group; X and Z each represents carbon, etc.; Y represents CO, etc.; R1 represents hydrogen, etc.; R2 and R3 each represents hydrogen, etc.; R4 and R5 each represents hydrogen, etc.; and symbol <u>--- </u> represents a single bond or double bond); a process for producing the same; and a use thereof. The compounds have a remarkable proliferation- inhibitory effect on tumor cells. A Cdk4 and/or Cdk6 inhibitor for use in the therapy of malignant tumor can hence be provided.

L'invention concerne des composés représentés par la formule générale (I), (dans laquelle Ar représente un groupe aromatique hétérocyclique azoté; X et Y représentent chacun carbone, etc.; Y représente CO, etc.; R¿1? représente hydrogène, etc.; R¿2? et R¿3? représentent chacun hydrogène, etc.; R¿4? et R¿5? représentent chacun hydrogène, etc.; et le symbole <u>---</u> représente une liaison simple ou double). L'invention porte également sur un procédé de production desdits composés et une utilisation de ceux-ci. Lesdits composés ont un effet inhibiteur de prolifération remarquable sur les cellules tumorales. Un inhibiteur de Cdk4 et/ou Cdk6, à utiliser dans le traitement des tumeurs malignes, peut ainsi être produit.
