Abstract: To observe the inhibitory effect of peptide compound GHGKHKNK on invasion and metastasis of mouse melanoma cell line B16-F10,in order to exploit a drug with higher pertinency and independent intellectual property rights of our country. Methods Cytotoxic effect of GHGKHKNK on mouse melanoma B16-F10 malignant melanoma cells was evaluated by MTT assay; C57BL/6J mice the were used to establish experimental lung metastasis models by injecting,B16-F10 malignant melanoma cells into the lateral tail vein the effect of GHGKHKNK on experimental lung metastasis in mice was detected with immunohisto chemical analysis. Results The inhibitory of cell 17.4% after treated with 10-1mol•L-1 GHGKHKNK for 48 h. High dose of GHGKHKNK (500μg•kg-1•d-1)clearly suppressed lung metastasis in mice. Conclusion GHGKHKNK has a stronger inhibitory effect on invasion and metastasis of B16-F10 malignant melanoma cells.

Key words: B16-F10 malignant melanoma cells, metastasis, C57BL, 6J mice.
