Biologically active derivatives of N6-benzyladenosine-5´-monophosphate
Cytokinin ribosides are phytohormones with anticancer activities against a range of cancer cell lines including leukemia stem cells. Their activity was confirmed in several xenograft models.
The present invention relates to the use of a compound of formula (I) for treatment of patients suffering from cancers or other proliferative disorders. Cytokinin ribosides, N6-substituted derivatives of adenosin, have only a limited water solubility which complicates preparation of pharmaceutically acceptable formulations. Introduction of 5´-phosphate moiety increases polarity and allows much higher solubility. Parent compound is released by the activity of serum/tissues esterases.
Laboratory scale, data on cell lines, limited ADME/Tox data.
The invention provides a novel class of cytokinin prodrugs with improved solubility profile.
