ABSTRACT
Objective The growth inhibitory effects of GlcNH_2?HCl,GlcNH_2 and NAG on human hepatoma SMMC-7721 cells in vitro was investigated.The antitumor activity of GlcNH_2?HCl against Sarcoma_(180) in KM mice was also investigated.Methods The cell viability in vitro was examined with MTT assay.DNA isolation and cell-cycle analyses were also performed.GlcNH_2?HCl was ig administered to Sarcoma_(180) KM mice.The inhibition rates,spleen and thymus index were calculated.Results GlcNH_2?HCl and GlcNH_2 resulted in a concentration-dependent reduction in hepatoma cell growth.The inhibition rates against SMMC-7721 cell of GlcNH_2?HCl and GlcNH_2 at concentration of 500?g?mL~(-1) were(50.24)% and 52.19%.As to the concentration of 1000?g?mL~(1), the rates were(82.21%) and 83.20%.This effect was accompanied by a marked increase in the proportion of S phase cells.Compared with the control,there was no significant difference among various concentrations of NAG,GlcNH_(2)?HCl exhibited inhibitiory effect against Sarcoma_(180) in mice at the dosage of 125~500 mg?kg~(-1),and the inhibition rate was about 27.84%~34.02%.The optimal inhibitory effect was 250 mg?kg~(-1).GlcNH_2?HCl could enhance the weights of thymus and spleen.In addition,it could promote lymphocyte transformation.Conclusion It is therefore postulated that the antitumor effect of GlcNH_2?HCl is probably host-mediated and cytocidal.
