The inhibitory effect of omega-3 such as linolenic acid (LNA), docosahexaenoic acid (DNA) and eicosapentaenoic acid(EPA) on the growth of normal cell lines and cancer cell lines was evaluated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyItetrazolium bromide (MTT) and 2,3-bis-2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-caboxanilide (XTT) methods. LNA was found to decrease the cell viability of human oral epithelioid carcinoma cells (KB) in the MTT assay, whereas EPA appeared to inhibit the cell adhesion activity of human skin melanoma cells (SK-MEL-3) in the XTT assay analysis. DPPH radical scavenging activity was examined on LNA, DHA and EPA at the concentration of 100 ${\mu}M$, where they showed about 53% scavenging activity. These results suggest that omega-3 unsaturated fatty acid has a potential anticancer activity.

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.

The methanol extract of the seed of Myristica fragrans (myristicaceae) demonstrated a potent inhibition on the proliferation of cultured human tumor cells such as A549 (non small cell lung), SK-OV-3 (ovary), SK-MEL-2(melanoma), XF498 (central nerve system) and HCT-15(colon). The MeOH extract was fractionated into three portions by serial solvent partition i,e., EtOAc soluble part, BuOH soluble part and remaining water layer. Among them, the EtOAc soluble part of the extract demonstrated a potent inhibition on the proliferation of cultured human tumor cells, Bioassay-guided fractionation of the EtOAc soluble part led to the isolation of six lignan constituents, i.e., safrole(1), machilin A (2), licarin B (3), macelignan (4), mesodihydroguaiaretic acid (5) and myristargenol A (6) as well as a large amount of myristic acid as active ingredients. Structures of the isolated active components (1-6) were established by chemical and spectroscopic means.
