ABSTRACT
Objective To study the antitumor activity of Xerophilusin G on S180 cells,and Its mechanism.Methods Modified MTT assay was used to test the effect of Xerophilusin G on the proliferation of S180 tumor cell strain.The influences on tumor growth and immune organs of mice with transplanted sarcoma (S180) were observed.The cell cycle of S180 cell lines and mouse sarcoma (S180) was analyzed by flow cytometry.The lymphocyte proliferation activity of spleen stimulating was tested.The level of IL-2 in serum of mice with transplanted sarcoma (S180) was measured by ELISA.Results The IC50 of Xerophilusin G in S180 cell lines was 19.80 μg·mL-1,the LD50 in mouse for Xerophilusin G was 121.11 mg·kg-1 through intraperitoneal injection.The tumor inhibition rate of Xerophilusin G was 32.11% and 41.60%,respectively at the doses of 3 and 6 mg · kg-1 (P < 0.05).Compared with the control,the thymus,kidney and cardiac index were decreased.The cell proportion at G0/G1 phase of mouse sarcoma (S180) was increased.T and B cell proliferation activities in tumor-bearing mice were enhanced (P < 0.05).As compared with control group,the serum level of IL-2 was decreased 90.9% and 77.1% in low-and medium-dose groups,respectively (P < 0.05).Conclusion Xerophilusin G has remarkable effects in sarcoma (S180) bearing mice.The antitumor mechanism of Xerophilusin G might be related with G0/G1 phase arrest of mouse sarcoma (S180) cells and enhancing the activity of T and B cell but not related with increasing the secreting of IL-2.
