Ginseng has an anti-cancer effect in several cancer models. This study was to characterize active constituents of ginseng and their effects on proliferation of prostate cancer cell lines, LNCaP and PC3. Cell proliferation was measured by $[^3H]$thymidine incorporation, the intracellular calcium concentration by a dual-wavelength spectrophotometer system, effects on mite-gen-activated protein (MAP) kinases by Western blotting, and cell attachment and morphologic changes were observed under a microscope. Among 11 ginsenosides tested, ginsenosides $Rg_3\;and\;Rh_2$ inhibited the proliferation of prostate cancer cells. $EC_{50}s\;of\;Rg_3\;and\;Rh_2$ on PC3 cells were $8.4{\mu}M\;and\;5.5{\mu}M$, respectively, and $14.1{\mu}M\;and\;4.4{\mu}M$ on LNCaP cells, respectively. Both ginsenosides induced cell detachment and modulated three modules of MAP kinases activities differently in LNCaP and PC3 cells. These results suggest that ginsenosides $Rg_3\;and\;Rh_2$-induced cell detachment and inhibition of the proliferation of prostate cancer cells may be associated with modulation of three modules of MAP kinases.

A new series of highly water soluble platinum(II) complexes {Pt(II)[1,3-bis(phenylthio) propane](trans- -1,2-diaminocyclohexane) (PC-1) and Pt(II)[1,3-bis-(phenythio)propane] cis-1,2-diaminocyclohexane(PC-2)} were synthesized, and characterized by their elemental analysis and by various spectroscopic techniques[infrared(IR), 13C-nuclear magnetic resonance (NMR)]. In vitro antitumor activity of new Pt(II) complexes was tested against P-388 and L-1210 mouse lymphocytic leukemia cell lines, PC-14 / P, PC-14/ADM and PC-14 / CDDP human pulmonary adenocarcinima, DU-145 human prostate carcinoma, HT-1376 human bladder carcinoma, ZR-75-1 human breast carcinoma, MKN-45/P and MKN-45/CDDP human gastric adenocarcinoma cell lines using colorimetric MTT[3-(4,5-dimethyl thiazol-2-yl)-2.5-diphenyltetrazoliumbromide] assay for cell survival and proliferation. PC-1 showed active against L-1210, P-388 leukemia, human lung, stomach, prostate, bladder and breast cancer cell lines, and the antitumor activity of these compounds were comparable or superior to those of PC-2 and displatin. The nephrotoxicities of PC-1 and PC-2 were found quite less than that of cisplatin using MTT and [3H] thymidine uptake in rabbit proximal tubule cells and human kidney cortical cells. Based on these results, this novel platinum (II) complex compound (PC-1) represents a valuable lead in the development of a new anticancer chemotherapeutic agent capable of improving antitumor activity and low nephrotoxicity.

유자는 성숙할수록 과피와 과육의 총페놀 함량은 많아지고 자유기 소거능이 높아지는 경향을 보였다. 유자로부터 추출한 18가지 용매 추출물의 항산화 활성과 전립선 암세포 DU 145, LN-CaP에 대한 세포독성 실험을 실시한 결과 과피와 과육 모두 미성숙한 유자 보다 성숙한 후 수확한 유자가 그 활성이 높게 나타냈다. 용매별로 살펴보면 과성숙 유자 과피, 과육의 클로로포름, 메탄올 추출물은 전립선 암세포 DU 145에 대하여 60% 이상의 세포사멸 효과를 나타났으며 메탄올 추출물의 효과도 농도에 따라 상당히 높은 것으로 나타났다. 또한 세포 조직을 현미경으로 살펴본 결과 추출물의 처리 농도가 증가할수록 세포 사멸이 쉽게 이루어지는 것을 확인 할 수 있었다. 이런 세포 사멸의 경향은 추출물의 자유기 소거 환성이 높을수록 높게 나타났다.

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.

Inositol hexaphosphate ($IP_6$) is a major constituent of most cereals, legumes, nuts, oil seeds and soybean. Previous studies reported the anticancer effect of $IP_6$ and suggested that co-treatment of $IP_6$ with inositol may enhance anticancer effect of $IP_6$. Although the anticancer effect of $IP_6$ has been intensively studied, the combinational effect of $IP_6$ and inositol and involved mechanisms are not well understood so far. In the present study, we investigated the effect of $IP_6$ and myo-inositol (MI) on cell cycle regulation and apoptosis using PC3 prostate cancer cell lines. When cell, were co-treated with $IP_6$ and MI, the extent of cell growth inhibition was significantly increased than that by $IP_6$ alone. To identify the effect of $IP_6$ and MI on apoptosis, the activity of caspase-3 was measured. The caspase-3 activity was significantly increased when cells were treated with either $IP_6$ alone or both $IP_6$ and MI, with no significant enhancement by co-treatment. To investigate the effect of $IP_6$ and MI of cell cycle arrest, we measured p21 mRNA expression in PC3 cells and observed significant increase in p21 mRNA by $IP_6$. But synergistic regulation by co-treatment with $IP_6$ and MI was not observed. In addition, there was no significant effect by co-treatment compared to $IP_6$ treatment on the regulation of cell cycle progression although $IP_6$ significantly changed cell cycle distribution in the presence of MI or not. Therefore, these findings support that $IP_6$ has anticancer function by induction of apoptosis and regulation of cell cycle. However, synergistic effect by MI on cell cycle regulation and apoptosis was not observed in PC3 prostate cancer cells.
