  • Raw meat of mackerel (Scomber japonicus) was salted by refined, sun-dried, bamboo, and KC1-added bamboo salts. Antimutagenic activity on N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Ames test and growth inhibitory effects of AGS human gastric and HT-29 human colon adenocarcinoma cells were investigated using methanol extracts of the salted mackerels. Mackerel salted sun-dried, bamboo, and KC1-added bamboo salts used increased the antimutagenic activities against MNNG, however, the sample treated with refined salt reduced the antimutagenic activity. Inhibitory effects of the salted-mackerels on the growth of human cancer cells were increased as dose dependent pattern. Mackerel salted with refined salt activated the growth of AGS human gastric adenocarcinoma cells, but mackerel salted with sun-dried, bamboo, and KC1-added bamboo salts kept or increased anticancer effect compared to the raw mackerel. Mackerel salted with KC1-added bamboo salt led to the highest antimutagenic and anticancer activities. These results suggest that antimutagenic and anticancer effects of mackerel during manufacturing of the salted-mackerel could be enhanced by using different kind of salts such as bamboo, or KC1-added bamboo salts.

  • Treatment of oral cancers with chemotherapeutic agents are evaluated as an effective method for remission to reduce cancer proliferation nowadays. But, minimization of side-effects such as bone marrow suppression, gastrointestinal toxicity and renal damage is another problem to be solved. Thus, a possible approach to develop a clinically applicable chemotherapeutic agents is to screen anticancer activity among traditional medicinal plants which have been used for thousands of years with very low side-effects in orient. In this study we focused on anti-oral cancer activities of momordin, which was medicinal plant extracts that was revealed anticancer activities, on KB cell(oral cancer cell). The results were as follow : 1. Momordin showed the excellent anti-oral cancer activity against KB cells. Obtained IC50 value of Momordin was $10.4{\mu}g/ml$. 2. When KB cells were treated with Momordin, dose and time dependent DNA fragmentation of KB cells were observed. DNA fragmentation was initiated on three days at the concentration of $20{\mu}g/ml$ Momordin. 3. Flow cytometry showed dose-dependent apoptotic cell increase of KB cells on Momordin. 18.55% apoptotic cell were observed up to 72 hours at the concentration of $20{\mu}g/ml$ of Momordin. 4. Momordin induced nonspecific apoptosis without specific cell cycle arrest. 5. Through MTT assay, DNA fragmentation assay and flow cytometric analysis. anticancer effect of Momordin against KB cell was induce of apoptotic cell death.

  • Background: Joboksansam, Korean bird wild ginseng, is an artificially cultivated wild ginseng germinated from bird feces. Although numerous pharmacologic activities of wild ginsengs have been reported, the beneficial effect of joboksansam in cancer has not been elucidated. In this study, we investigated the in vivo and in vitro anticancer activities of joboksansam powder. Methods: To evaluate the in vivo anticancer activity of joboksansam, we established a xenograft mouse model bearing RMA cell-derived cancer. Direct cytotoxicity induced by joboksansam powder was also investigated in vitro using (3-4-5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide (MTT) assay. The inhibitory activity of this powder on the activation of cell survival signaling involving Akt and Src was examined with immunoblot analysis. Results: Joboksansam powder displayed strong inhibitory activity against the increased tumor size, increased weight of total body and cancer tissues, and mortality of tumor-bearing mice. Joboksansam powder also suppressed the activation of survival regulatory enzymes Akt and Src, as assessed by phosphorylation levels in the immunoblot analysis of tumor tissues. Interestingly, the viability of RMA cells in vitro was directly decreased by joboksansam treatment. Conclusion: Overall, our results strongly suggest that joboksansam powder has the potential to protect against cancer generation by direct cytotoxic effects on cancer cells resulting from suppression of cell survival signaling.

  • The antioxidant and anticancer activities of Phellinus linteus, Inonotus obliquus, and Pleurotus ostreatus according to extraction methods were measured. The contents of polyphenolic compounds were higher in fermented extracts than those in water extracts. The contents were 192.4mg/100 $m{\ell}$ for Inonotus obliquus vinegar, 186.9 mg/100 $m{\ell}$ for Phellinus linteus vinegar, and 156.5 mg/100 $m{\ell}$ for Pleurotus ostreatus vinegar, respectively. EDA(electron donating ability) in Phellinus linteus that was highest among mushrooms was 83.9% in the water extract and 96.8% in the fermented extract. The growth of stomach cancer cells, SNU-719 was inhibited 62.4%, 65.5%, and 53.0% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, respectively and also the growth of liver cancer cells, Hep3B was inhibited 67.1%, 68.3%, and 57.6% by Phellinus linteus vinegar, Inonotus obliquus vinegar, and Pleurotus ostreatus vinegar, while the growth of normal cell, DC2.4 was not affected. Even though Phellinus linteus and Inonotus obliquus showed higher inhibition in cancer cell growth, Pleurotus ostreatus can be efficiently used for antioxidant and anticancer activities due to their cheap price in the market.

  • For the evaluation of the role of substituents of ar-turmerone for its anticancer activity, ar-turmerone (1a) and its analogs like 2-methyl-6-(4'-methyphenyl)-2-octen-4-one (1b), 2-methyl-6-phenyl-2-hepten-4-one (1c), 2-methyl-6-phenyl-2-octen-4-one (1d) and 2 methyl-6-(trans-4'-methylcyclohexyl)-2-hepten-4-one (1e) were preparedd and their cytotoxic activities against $L_{1210}$ cell were determined. Omission of methyl group at para-position dose not variate the cytotoxicity of ar-turmerone. Elongation of alkyl group at 6-position decreases $ED_{50}$ value. Saturation of aromatic ring of ar-turmerone markedly decreases the cytotoxicity. Therefore the smaller size of alkyl group at 6-position and aromatic ring of ar-turmerone should be essential for exhibiting its anticancer activity.

  • The anticancer and anti-inflammatory activities of probiotic Lactococcus lactis NK34 were demonstrated. Treatment of cancer cells such as SK-MES-1, DLD-1, HT-29, LoVo, AGS, and MCF-7 cells with 106 CFU/well of L. lactis NK34 resulted in strong inhibition of proliferation (>77% cytotoxicity, p < 0.05). The anti-inflammatory activity of L. lactis NK34 was also demonstrated in lipopolysaccharide-induced RAW 264.7 cells, where the production of nitric oxide and proinflammatory cytokines (tumor necrosis factor-α, interleukin-18, and cyclooxygenase-2) was reduced. These results suggest that L. lactis NK34 could be used as a probiotic microorganism to inhibit the proliferation of cancer cells and production of proinflammatory cytokines.

  • Cordyceps militaris, a caterpillar-grown traditional medicinal mushroom, produces important bioactive compounds, cordycepin (3'-deoxyadenosine) and militarin. Militarin is reported to possess anticancer activities against several tumor cells. An efficient synthetic method of militarin was developed to prepare muti-gram scale sample for bioassay. Militarin was successfully synthesized from commercial starting materials in 5 steps and 29.3% overall yields.

  • 4-(tert-Octyl)phenol derivatives bearing the D-mannitol substructure (6a, 6b, 7) were prepared from $\small{D}$-mannitol and evaluated their anticancer activity against human lung (A549) and prostate (Lncap, Du145, PC3) cancer cell lines. Among derivatives tested, the bis(tert-octyl)phenoxy compound 7 exhibited strongest proliferation inhibitory activities against human cancer cell lines tested, especially high sensitivity to human Du145 prostate cancer cells ($IC_{50}=7.3{\mu}M$).
