In the present study, we have evaluated cytotoxic effects of the chloroform soluble fraction of the methanolic extract of Perilla frutescens in human oral epitheloid carcinoma cells. The light microscopic study showed morphological changes of the treated cells. Cell membrane damaging activity was measured by the lactate dehydrogenase (LDH) assay and disruptions in cell organelles were determined by 3-(4,5-dime-thylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT), neutral red (NR) and sulforhodamine protein B (SRB) of colorimetric assay. These results suggest that Perilla frutescens retains a potential antitumor activity.

The extract and fractions of Rumex acetosa (Polygonaceae), a Korean medicinal plant, were examined for their cytotoxicities against five cultured human tumor cell lines, i.e. A549 (non-small cell lung), SK-OV-3 (ovary), SK-MEL-2 (melanoma), XF498 (central nerve system) and HCY15 (colon), using the SRB (sulforhodamine-B) method in vitro and antimutagenic activities by Ames test with Salmonella typhimurium TA98 and TA100 and SOS chromotest with E. coli PQ37. Among the tested samples, the methylene chloride fraction strongly inhibited the proliferation of each examined tumor cell line with $IC_{50}$ values ranged from 13.2 to $18.7\;{\mu}g/ml$ and showed potent antimutagenic activities with 96.1% and 96.7% at the concentration of 1 mg/plate against the mutagens, NPD and sodium azide, respectively. Its antigenotoxic activity was also very effective at the final concentration of $10\;{\mu}g/reaction$ tube against the mutagens, MNNG and NQO by SOS chromotest.

The cytotoxic activities of Pinellia ternate, Aconitum carmichaeli, Arisaema amurense, Aconitum kusnezoffii and Scutellaria baicalensis on monkey kidney cell (Vero) and human liver cell (WRL68) were evaluated by Sulforhodamine B Protein (SRB) and Tetrazolium-based (MTT) colorimetric assay methods The results were as fellows : 1 The Pinellia ternate and Arisaema amurense did not show the cytotoxic activities at any concentration without processing or natural drugs. 2 The extracts of Aconitum carmichaeli, Aconitum kusnezoffii and Scutellaria baicalensis showed cytotoxic activities. However, the cytotoxic activities of processing drugs were less effective than the natural drugs. 3. The cytotoxic activities on monkey kidney cell (Vero) and human liver cell (WRL68) of Aconitum carmichaeli was determined by MTT assay. The Kyungpo(京?) of Aconitum carmichaeli showed less concentrate than that of the Dangpo(唐?). The $IC_{50}$ value on monkey kidney cell (Vero) and human liver cell (WRL68) of Kyungpo was $937{\pm}29\;and\;731{\pm}31{\mu}g/ml$, respectively 4. The cytotoxicity on monkey kidney cell (Vero) and human liver cell (WRL68) of Scutellaria baicalensis showed strong activities without processing or natural drugs.

The cytotoxic activities of Cinnamomum cassia (Blume) bark-derived materials toward six human HeLa epithelioid cervix, A549 lung, SK-OV-3 ovarian, SK-MEL-2 melanoma, XF-498 central nerve system, and HCT-15 colon tumor cell lines were evaluated by using sulforhodamine B assay and compared to those of the anticancer agents, cisplatin and mitomycin C. The biologically active constituent of the Cinnamomum bark was characterized as trans­cinnamaldehyde by spectroscopic analysis. The cytotoxic activity of cinnamaldehyde against HeLa, SK-MEL-2, and HCT -15 cell lines was comparable to that of cisplatin and mitomycin C. The compound showed lower activity against A549, SK-OV-3, and XF-498 cell lines than the anticancer agents. Eugenol exhibited moderate activity against SK-OV­3, XF-498, and HCT-15 tumor cells, and trans-cinnamic acid, cinnamyl alcohol, $\alpha-pinene,\;and\;\beta-pinene$ showed little or no activity against model tumor cells. Cinnamaldehyde was not mutagenic against four strains (TA 98, TA 100, TA 1535, and TA 1537) of Salmonella typhimurium (Castel and Chalm). These results indicate at least one pharmacological action of C. cassia.

The cytotoxic activity of methanol extracts of 25 leguminous seeds in vitro was evaluated by sulforhodamine B assay, using the five human solid A549 lung, SK-OV-2 ovarian, SK-MEL-2 melanoma, XF-498 CNS and HCT-15 colon tumor cell lines. The responses varied with both cell line arid leguminous seed used. Extracts of Canavalia lineata and Glycine soja revealed potent cytotoxic activity against A549 arid SK-MEL-2 cell lines. Moderate activity was observed in the extracts of Cassia obtusifolia and Glyeine max var. chungtae, and C. lineata and Vigna angulasis against SK-MEL-2 and HCT-15 cell lines, respectively. The other seed extracts were ineffective against model tumor cell lines. Because of their potent cytotoxic activities, the activity of each solvent fraction from C. lineata and G. soja was determined and the potent activity was produced from their chloroform fractions. As a naturally occurring therapeutic agent, leguminous seeds described could be useful for developing new types of anti-tumor agents.

2-Chlorobenzoyl hydrazine refluxed with benzoyl isothiocyanate and phenyl isothiocyanate in ethanol for 3 hours to give benzamide derivative (1) and anilinederivative (2) on yield of 71%and 95%, respectively. Benzamide derivative (1) reacted with ethanolic sodium hydroxide on reflux to afford cyclization product (3), followed by general substitution reaction of two steps to give acetamide (5), and derivatived acetamides 7a-7k, while aniline derivative (2) reacted with ethanolic sodium hydroxide on reflux to afford another cyclization product (4). Thiol (4) reacted with N-phenyl chloroacetamide in the presence of potassim carbonate to give acetamide derivative (6). Compounds 1-7kwere evaluated for their growth inhibition against five cancer cell lines, including human lung carcinoma (A-549), human prostate cancer (DU145), human colon adenocarcinoma (HT-29), human malignant melanoma (SK-MEL-2) and human ovary malignant ascites (SK-OV-3) with sulforhodamine B (SRB) assay. All compounds (1-7k) showed low inhibition activities under 50% on 100M concentration.

Geranyl phenyl ethers 1, 2, 3, 4 and 5, 5-fluorouracil 6 and adriamycin 7 as references were tested for their growth inhibitory effects against tumor cell lines and NIH 3T3 fibroblasts using two different assays, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) and sulforhodamine B protein (SRB) assays. These results suggest that methyl-4-[{(2E)-3,7-dimethyl-2,6-octadienyl}oxy]-3-methoxy benzoate 1 showed growth inhibition activity against tumor cell lines. The maximum activity exhibited by methyl-4-[{(2E)-3,7-dimethyl-2,6-octadienyl}oxy]-3-hydroxybenzoate 3 against Staphylococcus epidermidis (MIC, $1,000{\mu}g/ml$).

Compounds 1 - 12 were tested for their growth inhibitory effects against tumor cell lines using two different 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) and sulforhodamine B protein (SRB) assays and antimicrobial activity. The cytotoxic activity of methyl-4-[{(2E)-3,7-dimethyl-2,6-octadienyl}oxy]-3-methoxy benzoate (1) exhibit more active than that of 5-fluorouracil (11) on human oral epithelioid carcinoma (KB, ATCC No. OCL 17) cell lines. But this compound (1) on human skin melanoma (SK-MEL-3, HBT 69) cell lines shows less active than that of adriamycin (12). However, compound 9 showed the antimicrobial activity against S. epidermidis (MIC, 15.625 ㎍/㎖), S. aureus, C. albicans (MIC, 31.25 ㎍/㎖), S. mutans, S. typhimurium, P. putida (MIC. 125 ㎍/㎖) and P. aeruginosa (MIC, 500 ㎍/㎖).

Objectives : The study was intended to investigate whether Iljoong-eum (IJE) significantly affects proliferation and growth of prostate cancer cells. Materials and Methods : In vitro, after the treatment of DU-145 and PC-3 cells with IJE, we performed Sulforhodamine B (SRB) method. In vivo, a total of 8 male nude mice subcutaneously transplanted with the PC-3 cell line were divided in 2 groups. An experimental group was given IJE orally at a dose of 4.29ml/kg per day from the 8th to 31st day following tumor injection. All mice were observed for 31 days, and sacrificed by CO2 gas asphyxiation at the end of the experiment. The mean tumor volume and body weight of both groups were compared using Student's t-tests. Results : In vitro, IJE inhibited significantly proliferation and growth of DU-145 cells and PC-3 cells. In vivo, IJE inhibited significantly proliferation and growth of PC-3 cells xenografted into athymic nude mice. Conclusions : Our data has shown that IJE is effective in suppressing the growth rate of prostate cancer cells.
