Here we report the cytotoxic activity of three known compounds isolated for the first time from Corydalis pallida (Papaveraceae). An isoquinoline alkaloid, berberine, exhibited cytototoxic activity against two human cancer cell lines, HT-1080 (human fibrosarcoma) and SNU-638 (human stomach adenocarcinoma), with $IC_{50}$ values of 3.2 and 3.4 $\mu$g/mL, respectively. N­trans-feruloyltyramine and N-trans-feruloylmethoxytyramine were also isolated from this plant but were inactive.

5-Fluorouracil (5-FU), an anticancer agent was covalently attached to the recently developed sorbitol-based G8 transporter, and the conjugate (7) with FITC was found to have an affinity toward mitochondria and to readily cross BBB to gain an entry into mouse brain. Measured by $IC_{50}$, the conjugate (9) without the fluorophore showed enhanced cytotoxic activity toward two types of multidrug-resistant cell lines. These results strongly suggest that the sorbitol-based G8 transporter can be utilized as a good CNS delivery vector.

The purpose of this study was to investigate the effect of Gleditsiae Spina on the pro life-ration of human cancer cell-lines. The effects of Gleditsiae Spina on the proliferation of A431, HeLa. MOLT-4, K562 cells, Balb/c 3T3 cells, mouse thymocytes, splenocytes and human lymphocytes were estimated by MTT colorimetric assay. The results were as follows; 1. Gleditsiae Spina increased the proliferation of HeLa, MOLT-4 and K562 cells. 2. The cytotoxicity of mitomycin C on K562 cells was increased by the combination of Gleditsiae Spina. 3. Gleditsiae Spina did not effect the proliferation of Balb/c 3T3 cells. 4. Gleditsiae Spina stimulated the proliferation of thymocytes. 5. Gleditsiae Spina stimulated the proliferation of splenocytes. 6. Gleditsiae Spina stimulated the proliferation of human lymphocytes.

In order to study the structure-activity relationship of 7, 8-dimethoxy-2-methyl-3-(4, 5-methylenedioxy-2-vinylphenyl)isoquinoline-1(2H) -one (2), which has exhibited significant antitumor activity, chemical modifications of 2 were performed to yield the corresponding products (3-7). Further systematic uses of an efficient procedure for the synthesis of 3-arylisoquinoline derivatives produced the substituted compounds (9a-9g), which were tested for in vitro antitumor activity against five different human cancer cell lines.

Substituted isoquinolin-1-ones (1) were synthesized to test their in vitro anticancer activity. 3-Biphenyl-H-methylisoquinolin-1-one (7) showed the most potent anticancer activity against five different human cancer cell lines.

Total phenol, total flavonoid, reducing powder, electron donating activity, ascorbic acid equivalent antioxidant capacity, antimicrobial and antiproliferative activities of olive leaf extracts were investigated. The contents of total phenol and flavonoid were 257.48 and 92.33 mg in 100 g of olive leaf extract, respectively. The reducing power of the olive leaf extract increased with concentration increasing. Electron donating activity was high in 100 ${\mu}g/mL$ treated olive leaf extract as 95.20%. The ascorbic acid equivalent antioxidant capacity of the olive leaf extract was 68.93 mg/g olive leaf extract. The olive leaf extracts showed relatively high antimicrobial activity against Escherichia coli, Salmonella typhimurium, Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes, and Pseudomonas aeruginosa. All of the cancer cell lines including MKN45, HCT116, NCI-H460, and MCF7 have 70-81% as effective growth inhibition.

The estrogenic activity of 47 plant extracts was assessed by reporter gene assay using MCF-7 breast cancer cell lines stably transfected with luciferase reporter gene. The estrogenic activity of food extracts was expressed as 17${\beta}$-estradiol(E2) equivalent concentration(EEQ), the concentration of E2 that resulted in the same relative luciferase unit(RLU) of the food extract of 0.2mg/$m\ell$.(omitted)

Four prostate-type triterpenes were isolated from a methanol extract of Alismatis Rhizoma by bioassay-guided isolation using in vitro cytotoxic assay. The compounds were identified as alisol B 23-acetate (1), alisol C 23-acetate (2), alisol B (3), alisol A 24-acetate (4) by spectroscopic methods. Amongst the compounds, alisol B (3) showed significant cytotoxicity against SK-OV3, B16-F10, and HT1080 cancer cell lines with $ED_50$ values of 7.5, 7.5, $4.9\mu\textrm{g}/ml$, respectively.

A series of 8-alkyl-and 8-aryl-8,9-dihydro-7H-isoindolo[5,6-g]quinoxaline-7,9-diones were synthesized using sultine chemistry as a key step in good yield. These compounds were evaluated for their in vitro cytotoxicity against six human cancer cell lines (HCT15, SK-OV-3, A549, SNB19, MCF7 and MCF7/ADR).

5,8-Epidioxycholest-6-en-3-ol (1), cholesterol (2), glycerol 1-palmitate (3) and glycerol 1,3-dioleate-2-stearate (4) were isolated from the methanol extract of the sea urchin Diadema setosum, which was collected from the Halong sea, Vietnam. Chemical structures were established based on extensive 1D, 2D-NMR, FAB-MS, EI-MS spectroscopic data and GC-MS analysis. The NMR spectral data of compound 1 were reassigned by using HMQC and HMBC. Compound 1 was found to have strong cytotoxic effect against various cancer cell lines, such as KB ($IC_{50}$, 2.0 $\mu\textrm{g}$/mL), FL($IC_{50}$, 3.93 $\mu\textrm{g}$/mL), and Hep-2 ($IC_{50}$, 2.4 $\mu\textrm{g}$/mL) by in vitro assay.
