METHODS: Benzhydroxamic acid derivative E was artificially synthesized. The gastric cancer line 7901 was selected to serve as the target cell. The effect of medicine E on tumor cell activity was examined by cell culture technology in vitro. The change of morphology and the ultrastructure after treatment with medicine E was observed with the optic microscope and the electron microscope.
