Abstract
We studied whether pretreatment of U-251 MG human brain tumor cells wi th the polyamine analog 1,19-bis-(ethylamino)-5,10-15-triazanonadecane (BE-4-4-4-4) affected the cytotoxicity of the toposionmerase II inhib itor etoposide. We found that BE-4-4-4-4 protected cells from the cyto toxic effects of etoposide. Possible mechanisms for this protection ma y be related to enhanced DNA-nuclear matrix association in analog-trea ted cells.
