Abstract
Selected 7-alkylidene substituted cephems were synthesized and subjected to antitumor assay. The effect of substituents was examined to establish structure-activity relationships. It was found that the intensive intracellular generation of nitric oxide induced by tert-butyl 7-alkylidene cephalosporanate sulfones could be also regarded as an additional cytotoxic factor taking place both in vitro and in vivo experiments.
