Pokeweed antiviral protein belongs to Ribosome-inactive Proteins. PAP has potent antiviral activity against many plant virus. pT1 was used as the template to amplify the deleted mutant PAP gene (N-deleted and N-,C-deIeted) by PCR and then the two genes were cloned into expression vector. Different IPTG-inducible expression vector containing different deleted mutant PAP gene was constructed and transferred into E.coli strain BL21 (DE3)-plysS.

Results The HSV infected cell culture system we established stable for utilization: Cellular damage and abnormal growth were not found in Hep-2 cells cultured with SDS at 10%×2-3×10-1(1.25mg/ml).The Hep-2 cells mainly became swelling and falling off and few of them formed syncytium after infected by HSV. The CPE occurred time and scale of CPE depended on multiplicity of infectionof HSV.SDS inhibited HSV yield with the manner of dosage dependent.

Adverse events were similar in both groups, and the incidence of symptomatic heart failure was lower than expected among those in the trastuzumab group (less than 2%), which supports "the accumulating evidence that trastuzumab can be given concurrently with anthracyclines with a low frequency of symptomatic cardiac dysfunction, provided that low cumulative doses or less cardiotoxic anthracyclines are used, and careful cardiac monitoring is done," the authors said.

In this paper, the stable Au complexes are classified according to the coordination atoms and their characteristic structure. The recent development of the researches on the antitumor activity of Au complexes including the structure-activity relationship, biological targets and the mechanisms of action are reviewed. The structure of the coordination ligand and the leaving group have great impact on the in vitro cytotoxicity of the Au complex. Many physical and biological methods are introduced to study the interaction between the Au complexes and the suspected bio-target, such as DNA, protein, mitochondrion, thio-containing biomolecules, etc. The interaction modes (intercalating, electrostatic interaction, covalent bonding, etc.) are focused to illustrate the reason for the antitumor activity of Au complexes.
