title: Cytolytic activities of benfluron metabolites and loss of transplantability.
abstract: The cytolytic activity of two benfluron metabolites, namely 7-dihydrobenfluron (DBF) and benfluron N-oxide (NOBF), has been studied using both Ehrlich ascites carcinoma (EAC) and P388 leukaemia cells. DBF showed a considerable cytolytic activity (activity of lactate and malate dehydrogenases, release of protein from the cells into the culture medium, morphological changes) particularly at higher concentrations. The highest concentrations caused a significant prolongation of the survival time of the experimental animals.
