The limonoid compound (28-deacetyl sendanin0 isolated from the fruit of Melia toosendan SIEB. et ZUCC. was evaluated on anticancer activity. According to a standard in vitro cytotoxicity assy, eight human cancer cell lines and SRB assay were introduced for present evaluation. As a positive standard, adriamycin was tested in parallel. The cell lines were originated from six different organs. In view of dose-response profiles to 28-deacetyl sendanin, the most sensitive cells were SF-539 and PC-3 which were derived from CNS and prostate, respecitively. In contrast, all the cell lines responded similarly to adriamycin to give rise to nearly indentical six cell lines were more sensitive to 28-deacetyl sendanin and two were more resistant. As a result, 28-deacetyl sendanin had more senstive and selective inhibitory effects on in vitro growth of human cancer cell lines in a comparison with adriamycin.

A triterpenoid(melianone) and a limonoid(28-deacetyl sendanin) were isolated from the chloroform fraction of Meliae toosendan Fructus, the rippen fruits of Melia toosendan SIEB. et ZUCC.(Meliaceae) and were applied to serial experiments to clarify the liver protective activities. We found that the compounds promoted slightly the drug metabolizing enzyme activities and decreased serum transaminase activities which was elevated by carbon tetrachloride intoxication. And also they slightly increased the secretion of bile juice in rat.

The MeOH extract of the fruits of Melia toosendan was selected for futher study by its cytotoxicity and effect on the human breast cancer cell line, MCF-7. The active principle obtained by activity guided fractionation followed by purification gave rise to a needle crystal. The structure was deduced by employing NMR and was determined to be identical with 28-deacetyl sendanin by comparison with published data. This compound induced morphological change of MCF-7 to be rounded with tubule at concentrations between $50\;{\mu}g/ml$ and $0.025\;{\mu}g/ml$. This compound, however, showed strong cytotoxic effect on Hepalclc7 and HepG2, and their $GI_{50}$ on the hepatoma cell lines were $0.238\;{\mu}g/ml$ and $0.805\;{\mu}g/ml$, respectively. Its effect on lymphocyte of mouse was stronger than hepatoma cell lines, and their $ED_{50}$ of polyclonal antibody response was $0.011\;{\mu}g/ml$, and $ED_{50}$ of cell viability was $0.039\;{\mu}g/ml$.
