    This study presents the first analysis of relationship between chemical structure of cytokinins and their cytotoxic effects against a panel of human cancer cell lines with diverse histopatothological origin. The results confirm the cytotoxic activity of N6-isopentenyladenosine, kinetin riboside, and N6-benzyladenosine and show that the spectrum of cell lines that are sensitive to these compounds is wider than previously reported. The first evidence that the hydroxylated aromatic cytokinins and cis-zeatin riboside have cytotoxic activities is presented. Most cell lines showed greatest sensitivity to ortho-topolin riboside. Cytokinin nucleotides were usually active in a similar concentration range to the corresponding ribosides. However, cytokinin free bases, 2-methylthio derivatives and glucosides showed little or no toxicity. The study shows that structural requirements for cytotoxic activity of cytokinins against human cancer cell lines differ from their activity in plant bioassays.
