概要
OBJECTIVE
The authors' previous studies have demonstrated that anuoning bullatacin and squamocin have anticancer activity in vitro. Squamocin could induce apoptosis of HL-60 cells. The purpose of this paper was to investigate cytotoxicity and antitumor effect of anuoning.
METHODS
MTT assay was used to examine the growth inhibition of anuoning on human colon carcinoma cell line (HT-29), human nasopharyngeal carcinoma cell line (SUNE1, CNE2), human liver carcinoma (bel-7402), human breast adenocarcinoma cell line (MCF-7) and human lung adenocarcinoma cell line (GLC-82). The models of mice S-180 sarcoma and HepS were used for in vivo antitumor test.
RESULTS
The IC50 of anuoning on CNE2, bel-7402, HT-29, SUNE1 cell were 0.044, 0.068, 0.446, and 1.617 micrograms/ml, respectively. The IC50 of anuoning on MCF-7 cell and GLC-82 cell were 1.857 and 3.481 micrograms/ml, respectively. Under the doses of 15, 30, and 60 micrograms/kg, i.p., qd x 10 d, the average tumor inhibitory rates of anuoning to mice tumor HepS were 36.9%, 51.8%, and 57.9%, respectively (P < 0.05). Under the same concentration, the average tumor inhibitory rates of anuoning on mice S-180 sarcoma were 43.0%, 52.1%, and 61.0%, respectively (P < 0.05).
CONCLUSIONS
The results indicate that the anuoning possess cell growth inhibition activity to various human tumor cells in vitro and antitumor effect in vivo.
