This study was carried out to find new antitumor agents from plant resource. Three cytotoxic agents were isolated from the root of Dictamnus albus by hexane extraction, silica gel column chromatography and HPLC. They were identified to be dictamnine $(C_{12}H_9NO_2)$, preskimmianine $(C_{17}H_{21}NO_4)$ and fraxinellone $(C_{14}H_{16}O_3)$ on the basis of spectroscopic evidences. In this study, it was newly found that these compounds possess a cytotoxic activity against lung lymphoma L1210 cell line. Among them. Preskimmianine was the most potent against the lymphoma L1210 with a $IC_{50}$ of $3.125\;{\mu}g/ml\;(10.3\;{\mu}M)$. Toxicity of preskimmianine against normal Iymphocyte was observed at the concentration of $50\;{\mu}g/ml\;(165\;{mu}M)$. These results support the pharmacological role of D. albus, a herb known as Paeksun in Korea and used as an anticancer agent in folk medicine.

A5E is complex of several medicinal herb ethanol extracts. The aim of this study is investigating the anticancer effect for non-small cell lung cancer. The antitumor effects of A5E on NCI-H460 were examined by regulation of cell proliferation, apoptosis, cell cycle arrest, mitochondrial membrane potential (${\Delta}{\Psi}_m$), and apoptosis-related protein. Cell proliferation was measured by MTS assay. Apoptosis induced by A5E was confirmed by Annexin V-fluorescein isothiocyanate (FITC)/Propidium Iodide (PI) staining, and cell cycle arrest was measured by PI staining. NF-${\kappa}B$ translocation was detected by immunofluorescence and MMP (${\Delta}{\Psi}_m$) was measured by JC-1 staining. The expression of extrinsic pathway molecules such as FasL and FADD were elevated, and procaspase-8 was processed by A5E. In addition, intrinsic pathway related molecules were altered. The Bcl-2 and Bcl-xl levels decreased, Bax increased, and cytochrome C was released. In addition, the mitochondrial membrane potential collapsed, and caspase-3 and poly-(ADP-ribose) polymerase were processed by A5E. Moreover, A5E affected the cellular survival pathway involving phosphatidylinositol 3-kinase (PI3K)/Akt and NF-${\kappa}B$. PI3K and Akt were downregulated, also NF-${\kappa}B$ expression was decreased, and nuclear translocalization was inhibited by A5E. These results suggested that A5E delays proliferation, inhibit cell cycle progression and induce apoptosis in human lung cancer cell. We conclude that A5E is a potential anticancer agent for human lung carcinoma.

Background: The transcription factor signal transducer and activator of transcription 3 (Stat3)is constitutively activated in many human cancers. It promotes tumor cell proliferation,inhibits apoptosis, induces angiogenesis and metastasis, and suppresses antitumor hostimmune responses. Therefore, Stat3 has emerged as a promising molecular target for cancertherapies. In this study, we evaluated the Stat3-suppressive activity of 38 herbal medicinestraditionally used in Korea.Methods: Medicinal herb extracts in 70% ethanol were screened for their ability to suppressStat3 in the A549 human lung cancer cell line. A Stat3-responsive reporter assay system wasused to detect intracellular Stat3 activity in extract-treated cells, and Western blot analyseswere performed to measure the expression profiles of Stat3-regulated proteins.Results: Fifty percent of the 38 extracts possessed at least mild Stat3-suppressive activities(i.e., activity less than 75% of the vehicle control). Ethanol extracts of Bupleurum falcatumL., Taraxacum officinale Weber, Solanum nigrum L., Ulmus macrocarpa Hance, Euonymus alatusSieb., Artemisia capillaris Thunb., and Saururus chinensis (Lour.) Baill inhibited up to 75% of thevehicle control Stat3 activity level. A549 cells treated with these extracts also had reducedBcl-xL, Survivin, c-Myc, and Mcl-1 expression.Conclusion: Many medicinal herbs traditionally used in Korea contain Stat3 activity-suppressing substances. Because of the therapeutic impact of Stat3 inhibition, these resultscould be useful when developing novel cancer therapeutics from medicinal herbs.

Ginsenosides are metabolized (deglycosylated) by intestinal bacteria to active forms after oral administration. 20(S)-Protopanaxadiol $20-O-{\beta}-D-glucopyranoside$ (M1) and 20(S)-protopanaxatriol (M4) are the main intestinal bacterial metabolites (IBMs) of protopanaxadiol- and protopanaxatriol-type glycosides. M1 was selectively accumulated into the liver soon after its intravenous (i.v.) administration to mice, and mostly excreted as bile; however, some M1 was transformed to fatty acid ester (EMl) in the liver. EM1 was isolated from rats in a recovery dose of approximately $24mol\%.$ Structural analysis indicated that EM1 comprised a family of fatty acid mono-esters of M1. Because EM1 was not excreted as bile as Ml was, it was accumulated in the liver longer than M1. The in vitro cytotoxicity of M1 was attenuated by fatty acid esterification, implying that esterification is a detoxification reaction. However, esterified M1 (EM1) inhibited the growth of B16 melanoma more than Ml in vivo. The in vivo antitumor activity paralleled with the pharmacokinetic behavior. In the case of M4, orally administered M4 was absorbed from the small intestine into the mesenteric lymphatics followed by the rapid esterification of M4 with fatty acids and its spreading to other organs in the body and excretion as bile. The administration of M4 prior to tumor injection abrogated the enhanced lung metastasis in the mice pretreated with 2-chloroadenosine more effectively than in those pretreated with anti-asialo GMl. Both EM1 and EM4 did not directly affect tumor growth in vitro, whereas EM1 promoted tumor cell lysis by lymphocytes, particularly non-adherent splenocytes, and EM4 stimulated splenic NK cells to become cytotoxic to tumor cells. Thus, the esterification of IBM with fatty acids potentiated the antitumor activity of parental IBM through delay of the clearance and through immunostimulation. These results suggest that the fatty acid conjugates of IBMs may be the real active principles of ginsenosides in the body.

In an attempt to deduce which plants might have been used for their anticancer activities in traditional oriental herb medicine, 127 prescriptions were selected from 'Dong-Eui-Bo-Gam', the Classic Handbook of Korean Traditional Medicine, written by $H_{UH}$ Jun and published in 1613. These are the prescriptions indicated for the systemic treatment of various tumors and some conditions resembling tumors, e.g. inflammatory masses and indurations, and they include 150 natural products of plant origin. The frequency of appearance of each medicinal plant in these selected prescriptions was compared with the frequency of its appearance in all prescriptions listed in 'Bang-Yak-Hap-Pyon', another popular Oriental Medicine Formulary in Korea, written by $H_{WANG}\;Pil-Su$ in 1885. From the latter book, $H_{ONG}$ has recently enumerated frequencies of 235 medicinal plants included in a total of 467 prescriptions. Chi-square tests revealed that 11 plant remedies appear with significantly higher frequency in the prescriptions for "tumors", and 10 for "inflammations". The plants with potential antitumor activities, in decreasing order of statistical significance, are Scirpus maritimus, Curcuma zedoaria, Prunus persica, Rheum coreanum, Foeniculum vulgare, Rhus vernifera, Daphne pseudogenkwa, Galarhaeus sieboldiana, Croton tiglium, Raphanus sativus and Galarhaeus pekinensis. The drugs for potential antibacterial or anti-inflammatory activities are Olibanum(Frankincense), Forsythia coreana, Lonicera japonica, Gleditchia officinalis, $M_{YRRH}$, Trichosanhes kirilowii, Astragalus membranaceus, Rheum coreanum, Platycodon grandiflorum and Fritillaria verticillata. Despite the uncertainties involved in the terminology of various diseases used in pre-modern medicine, and the reservations about the efficacy of remedies used for those diseases, it would be worthwhile to investigate these few selected plants for anticancer, antibacterial, anti-inflammatory or antifungal effects, employing modern scientific methodology.
