  • 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.

  • Phellinus linteus was examined on its immunostimulating activities using an in vitro imunization and plaque forming cell assay. When lymphocytes were exposed to the extract of Phellinus linteus, the number of antibody forming cell was increased. In in vitro plaque forming cell assay, the immunostimulating effect was about 4.8 and 5.0 times of unimmunized control in polyconal and T-independent antibody response, respectively. Especially, Phellinus linteus significantly increased the antigenicity of TNP-LPS used as T-independent antigen. But Phellinus linteus did now show a mitogenic effect on B-lymphcytes. These results suggest that immunostimulating activity of Phillinus lintues might be associated with a functional stimulation of B-lympohocyte involved in humoral immune response.
