Derivatives of 2-phenyl-3-hydroxyquinoline-4(1H)-one of the general formula (II), where X represents a nitro group, amino group, and Y represents an atom of halogen, oxygen or sulphur substituted by Cto Calkyl or phenyl group, whereby both the alkyl and phenyl group may be further substituted and the substituents may be identical or different, or by nitrogen substituted independently by hydrogen, Cto Calkyl, Cto Calkyl, which may be substituted among others by halogen, hydroxy, Cto Calkoxy or Cto Calkylamino group, or may form a saturated or unsaturated heterocyclic ring with 5 to 7 atoms, where the individual ring atoms comprise atoms of carbon, and any of the carbon atoms may be substituted by an atom of nitrogen, sulphur or oxygen, X and Y together form an imidazo group, or imidazo group substituted by Cto Calkyl, which may be substituted among others by halogen, hydroxy, Cto Calkoxy or Cto Calkylamino group, CHO or acetylgroup, or a heterocyclic ring with 5 to 6 atoms, where the ring atoms may be further substituted. Methods of preparation of these compounds are described. In addition, their cytostatic, cytotoxic, antiproliferation and immunosuppressive activity is described including examples of their potential pharmacological and pharmaceutical utilization.
