Cannabidiol derivatives (1, 2 and 3), and 5-fluorouracil (4, 5-FU) were tested for their growth inhibitory effects against human oral epitheloid carcinoma cell lines (KB) using two different 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and sulforhodamine B protein (SRB) assay. These compounds showed a potent inhibitory activity in vitro in the micromolar range against KB cell lines. In general, the antitumor activity of these compounds (1, 2, 3 and 4) was in a dose-dependent over the micromolar concentration ranges from $1\;{\mu}M\;to\;100\;{\mu}M$. The comparison of $IC_{50}$ values of these compounds in tumor cell lines shows that their susceptibility to these compounds decreases in the following order: CBD > 5-FU > CBDME > CBDDE by the MTT assay and SRB assay. Cannabidiol derivatives (1, 2 and 3), and 5-FU were tested for their cytotoxic effects on NIH 3T3 fibroblasts using two different MTT assay and SRB assay. These compounds exhibited potent cytotoxic activities in vitro in the micromolar range against NIH 3T3 fibroblasts. In general, the cytotoxic activities of these compounds (1, 2, 3 and 4) were in a dose-dependent over the micromolar concentration range $1\;{\mu}M\;to\;100\;{\mu}M$. The comparison of $CD_{50}$ values of these compounds on NIH 3T3 fibroblasts shows that their susceptibility to these compounds decreases in the following order; CBD > 5-FU > CBDDE > CBDME by MTT assay, CBD > 5-FU > CBDME > CBDDE by SRB assay. These results suggest that cannabidiol (1, CBD) retains the most growth-inhibitory activity against KB cell lines.

The anticancer effect of methanol extracts from common Chinese cabbage kimchi(CC kimchi ) and organically cultivated Chinese cabbage kimchi (OC kimchi) was studied on the cell growth, MTT assay and SRB assay using AGS human gastric cancer cells. Methanol extracts from CC kimchi and OC kimchi exhibited the anticancer activites in vitro and in vivo. Methanol extract from 6 day-fermented CC kimchi and OC kimchi inhibited the growth of AGS cells by 55.2 and 60.7% , respectively. At MTT assay an dSRB assay, 6 day-fermented OC kimchi showed higher inhibition rate (MTT : 42%, SRB : 61%) than 6 day-fermented CC kimchi(MTT : 33%, SRB : 52%). Methanol extracts from 6-day fermented CC kimchi and OC reduced the tumor formation and prolonged the life span of sarcoma-180 cell injected Balb.c mouse. OC kimchi treated group resulted in the smaller tumor weight of 4.58$\pm$0.32g compared th the CC kimchi group of 5.40$\pm$0.78g and the control group of 7.50$\pm$0.54g and OC kimchi treted group (25.3 days) lived longest among control (20.2days ) and CC kimchi(23.5days) treted groups.

Cannabigerol (1, CBG), methyl 4-[(2E)-3,7-dimethyl-2,6-octad ienyl)oxy]-3-methoxybenzoate (2, DTM), 5-fluorouracil (3, FU) as a reference, and cannabidiol (4, CBD) were tested for their growth inhibitory effects against KB(ATCC NO, OCL 17) cell lines using two different assays, the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) assay and the sulforhod-amine B protein (SRB) assay. These compounds showed inhibitory activity in vitro in the micromolar range against KB cell lines. In general, the antitumor activities of these compounds (1, 2, 3 and 4) were dose-dependent over the micromolar concentration range of 1 to 100 M. The comparison of $IC_{50}$ values of these compounds in tumor cell lines showed that their susceptibility to these compounds decreases in the following order: DTM > CBD > 5-FU > CBG by MTT assay and DTM = CBD > 5-FU > CBG by SRB assay. CBG 1, DTM 2, 5-FU 3, and CBD 4 were tested for their cytotoxic effects on NIH 3T3 fibroblasts using two different assays, the MTT assay and SRB assay. These compounds exhibited potent cytotoxic activities in vitro in the micromolar range against NIH 3T3 fibroblasts. In general, the cytotoxic acivities of these compounds (1, 2, 3 and 4) were dose-dependent over the micromolar concentraion range of 1 to 100 M. The comparison of $CD_{50}$ values of these compounds in NIH 3T3 fibroblasts shows that their susceptibility to these compounds in decreases the following order(:) CBD > 5-FU > DTM > CBG by MTT assay, CBD > 5-FU > CBG > DTM by SRB assay.

본 연구에서는 전통적으로 담석증, 신장치료 등의 한약제로 많이 사용하는 대왕을 여러 용매를 사용하여 얻은 대왕추출물 분액에 대한 세포독성을 여부를 MTT 정량법, NR 정량법, SRB 정량법을 이용하여 조사하였다. 1. 추출 용매 methylene chloride, ethyl acetate, butanol, water로부터 얻은 대왕추출물 모두 처리농도에 따라 세포에 미치는 영향이 증가하였다. 2. Butanol을 용매로 사용하여 얻은 대왕추출물 분액이 다른 3가지 용매로부터 얻은 대왕추출물보다 세포에 미치는 영향이 크게 나타났고 water를 용매로 사용하여 얻은 추출물이 A498 세포주에 미치는 영향이 가장 낮게 나타났다. 3. Butanol을 추출 용매로 하여 얻은 대왕추출물이 A498 세포주에 미치는 영향이 가장 컸는데 그 추출물에 대한 MTT$_{50}$, NR$_{50}$, SRB$_{50}$값은 각각 0.63mg/ml, 0.65mg/ml, 0.68mg/ml이었고, 가장 영향이 적은 water의 경우 MTT$_{50}$, NR$_{50}$, SRB$_{50}$값은 각각 0.84mg/ml, 0.82mg/ml, 0.80mg/ml이었다. 4. 정량방법 간의 대왕추출물에 대한 반응은 MTT 정량법이 가장 민감하게 나타났다.

This study was carried out to develop antitumor agents based on effects of the ethyl acetate soluble fraction of the methanolic extract of Lonicerae flos on human oral epitheloid carcinoma cells. Human oral epitheloid carcinoma cells were cultured in RPMI-1640 media containing 10% fetal bovine serum, antibiotic, and fungizone. After incubation for 24 hrs, the cells were treated with A, B, C, D, and E fractions for 48hrs under the same condition. MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide), NR (Neutral red) and SRB (Sulforhodamine B protein) assay were performed. The light microscopic findings were observed by inverted microscope. In MTT assay, fraction B was shown significant antitumor activity (P<0.001), fraction E was shown significant antitumor activities (P<0.05), but the other fractions were not shown. In NR assay, fraction B was shown significant antitumor activity (P<0.001). In SRB assay, fractions B was shown significant antitumor activities (P<0.01). fractions A and D were shown significant antitumor activities (P<0.05). but the other fractions were not shown. In light microscopy. the fraction B of the ethyl acetate soluble fraction of the methanolic extract of Lonicerae flos showed the highest antitumor activity. These finding suggested that fraction B possessed the most antitumorous agent.
