Fungal perylenequinones have photodynamic activity and are promising photosensitizers for photodynamic therapy (PDT). Here, we investigated the bactericidal and antitumor activities of phleichrome from the fungal perylenequinone family in vitro. Photodynamic bactericidal activity of phleichrome was analyzed by agar-well diffusion method under dark and illuminated conditions. The photodynamic antitumor activity of phleichrome was analyzed in MCF-7, HeLa, SW480, and HepG2 human cancer cell lines using in vitro cytotoxicity assays. Photodynamic bactericidal activities against Gram-negative and Gram-positive bacteria were species-specific. Antitumor activity against all tumor cell lines increased under the illuminated condition. Depending on the results of the analyses, Phleichrome has potential for further drug development related to its antibacterial and antitumor activities.

Polysaccharide fraction isolated from Coriolus versicolor (Copolang) was studied on the antitumor activity and immunostimulation activities with reference to PS-K. Copolang showed nearly equal antitumor activities to the PS-K and exhibited marked augmentation effects on the antibody mediated hypersensitivity reaction, delayed type hypersensitivity reaction and NK-cell activity in tumor bearing mice. But it did not show any noticeable effect on the antibody secreting cell and macrophage function in normal mice. These results indicate that the antitumor activity and immunostimulating effect of Copolang are comparable to those of PS-K.

Chitin, a linked polysaccharide composed of 2-acetamido-2-deoxy-$\beta$-D-glucopytanose residues, is distributed widely in nature. It has been utilized on various application field due to the development of chitin derivatives such as chitosan, partial deacetylated chitin, carboxylmethyl chitin, sulfated chitin, and so on. Chitin and chitosan have been recently interested in antitumor and antimicrobial activities, because of a powerful tumor inhibitory effect against experimental mouse tumors. Especially, the oligosaccharides obtained by partial degradation of them exhibited a remarkable antitumor effect against sarcoma 180, MM 48 and Meth Asolid tumors and antimetastatic effect against Lewis lung carcinoma in mice. This review describes on antitumor effects of chitin, chitosan and their oligosaccharides by their mechanism of action involving enhancement of immunological system.

Thirty species of Korean medicinal plants which have been frequently used in Oriental herb prescriptions were evaluated on their acute toxicity and potential antitumor activities against P-388 lymphocytic leukemia. The criteria for toxicity evaluation of measuring weight loss, toxicity day survivors and computing log cell kill indicated that 11 species possessed acute toxicity according to the doses administered. No significant antitumor activities were observed while the root of Angelica gigas Nakai (Umbelliferae) exhibited only 24% increased life span.

The polysaccharide fraction from Taraxii Herba showed potent immunopotentiating activities with antitumor activities. The fraction having small amount of protein inhibited the growth of solid tumor and increased peritoneal exudate cells and immunoorgan weights in normal mice, and also increased hypersensitivities in tumor bearing mice.

하이아미의 정조와 현미상태에 대해 일품벼를 대조구로 하여 항산화성분의 함량과 에탄올 추출물에 대한 in vitro 항산화활성 및 항암활성을 측정하였다. 하이아미의 정조 및 현미 추출물의 총 폴리페놀 함량은 각각 6.31 및 3.75 mg/g으로 나타났으며, 일품은 각각 5.66 및 3.47 mg/g으로 나타나 하이아미가 약간 높은 것을 알 수 있었다. 하이아미의 정조와 현미 추출물의 $\gamma$-oryzanol 함량은 각각 33.53 및 39.47 mg/100 g으로 나타났으며, 일품의 경우 각각 24.33 및 28.68 mg/100 g으로 나타나 일품에 비해 하이아미에서 높은 함량을 보이는 것으로 나타났다. 하이아미와 일품벼 정조 및 현미의 70% 에탄올 추출물에 대한 DPPH radical, hydrogen peroxide, superoxide radical 및 hydroxyl radical 소거활성을 5 mg/mL의 농도에서 측정한 결과 하이아미가 일품에 비해 높은 것으로 나타났으며, 정조 추출물이 현미 추출물보다 높은 radical 소거활성을 보이는 것으로 나타났다. 70% 에탄올 추출물에 대한 in vitro 항암활성을 측정한 결과 정조 및 현미 추출물의 억제 활성은 용량 의존적으로 증가하는 것으로 나타났으며, 특히 하이아미는 위암 및 유방암세포에 높은 활성을 보였으며, 일품은 대장암 및 간암세포에 대해 높은 활성을 보였다.

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.

The aim of this study is to evaluate the antioxidant, antimicrobial, and antitumor activities of various concentrations of partially purified substance(s) from green tea seed (Camellia sinensis L.). The total polyphenol contents of each fraction (non-adsorption fraction: F-1, fraction eluted with 40% methanol: F-2, and fraction eluted with 100% methanol: F-3) purified by Diaion HP-20 column chromatography were, in the increasing order: F-1 (3.7 mg tannic acid equivalents, TAB/g) < F-3 (23.2 mg TAB/g) < seed extracts (26.2 mg TAB/g) < F-2 (42.7 mg TAB/g). The scavenging activities toward the 1,1-diphenyl-2-picyrylhydrazyl (DPPH) radical were, in decreasing order: F-2 (93.3%) > butylated hydroxytoluene (BHT; 89.8%) > ascorbic acid (89.3%) > leaf extracts (70.3%) > F-3 (15.9%) > seed extracts (15.8%) > F-1 (14.8%) at a 0.1% concentration. In studies on antimicrobial activities, the results indicate that the growth of yeast (Candida albicans KCCM 11282 and Cryptococcus neoformans KCCM 50544) was inhibited more so than that of other fungi (Alternaria alternate KCTC 6005 and Rhizoctonia solani). In addition, it appears that the antitumor activities of the F-1, F-2, and F-3 fractions at a concentration of $50\;{\mu}g/mL$ showed 6, 7, and 23% growth inhibition of the HEC-1B cell line, 14, 11, 82% inhibition of the HEP-2 cell line, and 8, 16, and 81% inhibition of the SK-OV-3 cell line, respectively. Overall these results indicate that the antioxidant activity is greatest in the F-2 fraction, and the antimicrobial and antitumor activities are greatest in the F-3 fraction.
