OBJECTIVE:To prepare sulfadiazine silver film and establish a way for its quality control.METHODS:Polyvinyl alcohol was used as the main excipients for the preparation of film;the dead-stop titration was used to determine the content of sulfadiazine silver;the stability of the film sample was observed.RESULTS:The content of sulfadiazine silver was 98.9%～100.7%,the average recovery rate was 100.6%,RSD=0.69%(n=6).CONCLUSION:The prepared sulfadiazine silver film is stable in quality,accurate in content,simple in preparation and the testing method is fast.

Kinesin spindle protein ( KSP) inhibitors is an important direction for the discovery of anticancer agents. Several KSP in-hibitors have been studied in clinic trials. The discovery of ATP-competitive KSP inhibitors may be a new approach for searching novel a-gents to overcome the mutation-mediated resistance to the allosteric inhibitors. The progress in the discovery of ATP-competitive KSP in-hibitors was reviewed in the paper to provide reference for the further development of KSP inhibitors.
