Abstract

Geraniol (1), olivetol (2), cannabinoids (3 and 4) and 5-fluorou.a.il (5). were tested for their growth inhibitory effects against SK-MEL-3 cell lines using two different 3-(4,5-dimethylthiazol- 2yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and sulforhodamine B protein (SRB) assay. These compounds showed inhibitory activity in vitro in the micromolar range against SK-MEL-3 cell lines. In general, the antitumor activity of these compounds (1, 2, 3, 4 and 5) was in a dose-dependent over the micromolar concentration range $1\;to\;100{\mu}M$. The comparison of $IC_{50}$ values of these compounds in tumor cell lines shows that their susceptibility to these compounds decrease in the following order : OLVTL > CBG > CBD > 5-FU > CRNL in MTT assay, CBG > OLVTL > CBD > GRNL > 5-FU in SRB assay. Cannabinoids (3 and 4) and 5-fluorouracil (5) were tested for their cytotoxic effects on NIH 373 fibroblasts using two different MTT assay and SRB assay. These compounds exhibited potent cytotoxic activities in vitro in the micromolar range against NIH 373 fibroblasts. In general, the cytotoxic activities of these compounds (3, 4 and 5) were in a dose-dependent over the micromolar concentration range $1\;to\;100{\mu}M$. The comparison of $CD_{50}$ values of these compounds on NIH 373 fibroblasts shows that their susceptibility to these compounds decrease on the following order ; CBD > 5-FU > CBG in MTT assay and SRB assay. Cannabigerol (3) was shown the least cytotoxic activity on NIH 373 fibroblasts. Cannabigerol (3) exhibited the most growth-inhibitory activity against SK-MEL-3 cell lines.

제라니올 (1), 올리비톨 (2), 카나비노이드 (3 과 4)와 5-플로르우라실 (5)을 MTT 정량분석법과 SRB 정량분석법으로 인체 피부흑색종세포에 대하여 성장 억제효과를 평가 하였다. 이들 화합물(1, 2, 3, 4와 5)은 마이크로 몰 농도의 범위에 대하여 억제 활성을 나타내었다. 일반적으로 이들 화합물은 $1{\mu}M\;-\;100{\mu}M$ 농도범위에서는 투여량에 따라 항암활성을 나타내었다. 인체 피부흑색종세포에 대한 이들 화합물의 50 %억제 농도 효과에 대한 비교는 다음과 같은 순서로 항암활성이 감소하였다. MTT 정량분석법 ; OLVTL >CBG > CBD > 5-FU >GRNL, SRB 정량 분석법 ; CBG > OLVTL > CBD > CRNL > 5-FU, 카나비노이드 (3 과 4)와 5-플로르우라실 (5)을 MTT정량분석법과 SRB정량분석법으로 인체정상세포에 대하여 독성효과를 측정하였다. 이들 화합물은 마이크로몰농도의 농도범위에서는 투여량에 따라 세포독성을 보였다. 인체정상세포에 대한 이들 화합물의 50 % 독성효과에 대한 비교는 다음과 같은 순서로 세포독성이 감소하였다. MTT정량분석법과 SRB정량분석법 ; CBD > 5-FU > CBG. 따라서 카나비지놀 (3)은 인체정상세포에 대하여 가장 낮은 세포독성을 나타내었다. 따라서 카나비지놀 (3)은 인체 피부흑색종세포에 대하여 가장 강한 성장억제활성을 보였다.
