The cyclic voltammetric response of glucose oxidase modification on the surface of a functionalized graphene oxide electrode showed a surface-confined reaction and an effective redox potential near zero volts, with a wide linearity of 0.1-20 mM and a sensitivity of 7.

Rapid identification and preparative isolation of antioxidant components in licorice.

This study employed the online HPLC-2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonate radical cation (ABTS(+*)) bioassay to rapidly determine antioxidant compounds occurring in the licorice extract of Glycyrrhiza uralensis. The negative peaks of the ABTS(+*) radical scavenging detection system, which indicated the presence of antioxidant activity, were monitored by measuring the decrease in absorbance at 734 nm. The ABTS(+)-based antioxidant activity profile showed that three peaks exhibited antioxidant activity, and then the high-speed counter-current chromatography technique of preparative scale was successfully applied to separate the three peaks I-III in one step from the licorice extract.

Apoptosis of DU145 human prostate cancer cells induced by dehydrocostus lactone isolated from the root of Saussurea lappa.

Saussurea lappa (SL) is a plant regularly utilized in traditional herbal medicine, and in vitro cell culture studies have demonstrated that SL has anti-ulcer, anti-inflammatory, and anti-tumor properties. In order to explore the possibility that SL exerts chemopreventive effects in androgen-independent prostate cancer, we attempted to determine whether the hexane extract of SL (HESL) induces apoptosis of DU145 cells, as well as the mechanisms underlying this effect. HESL substantially reduced the number of viable cells and induced apoptosis in DU145 cells in a dose-dependent manner.

Protein glycation inhibitors from the fruiting body of Phellinus linteus.

To characterize active principles for prevention and treatment of diabetic complications, the isolation of protein glycation inhibitors from the fruiting body of Phellinus linteus was conducted in vitro using the model systems of hemoglobin-delta-gluconolactone (early stage), bovine serum albumin-methylglyoxal (middle stage), and N(alpha)-acetyl-glycyl-lysine methyl ester-D-ribose (last stage) assays. Nine compounds were isolated from the active ethylacetate fraction of the fruiting body and identified as protocatechuic acid (1), protocatechualdehyde (2), caffeic acid (3), ellagic acid (4), hispidin (5), davallialactone (6), hypholomine B (7), interfungins A (8), and inoscavin A (9) by spectroscopic analyses. At the early stage of protein glycation, compounds 6, 8, and 9 exhibited inhibitory activity on hemoglobin A(1C) formation.

Licochalcone A isolated from licorice suppresses lipopolysaccharide-stimulated inflammatory reactions in RAW264.7 cells and endotoxin shock in mice.

Licochalcone A (LicA), a major phenolic constituent of the licorice species Glycyrrhiza inflata, exhibits various biological properties, including chemopreventive, anti-bacterial, and anti-spasmodic activity. We report that LicA inhibits inflammatory reactions in macrophages and protects mice from endotoxin shock. Our in vitro experiments showed that LicA suppressed not only the generation of nitric oxide (NO) and prostaglandin (PG)E(2), but also the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 induced by lipopolysaccharide (LPS) in RAW264.

Induction of apoptosis in HT-29 colon cancer cells by phloretin.

Phloretin, which is present in apples and pears, has been found to inhibit the growth of several cancer cells and induce apoptosis of B16 melanoma and HL60 human leukemia cells. The present study examined whether and how phloretin induces apoptosis of HT-29 human colon cancer cells. Phloretin (0-100 micromol/L) substantially decreased viable cell number and induced apoptosis of HT-29 cells in a dose-dependent manner.

Antiinflammatory activities of Rubus coreanus depend on the degree of fruit ripening.

The dried unripe fruit of Rubus coreanus, which is well-known in Korea and referred to as 'Bok-bun-ja', has been employed as a traditional medicine for centuries. This crude drug is utilized in Korea for the management of impotence, spermatorrhea, enuresis, asthma and allergic diseases. The principal objective of the present study was to conduct a comparison of the antiinflammatory effects of ethanol extracts of the unripe (URCE), half-ripened (HRCE) and ripe fruits (RCE) of Rubus coreanus.

Isoliquiritigenin (ISL) inhibits ErbB3 signaling in prostate cancer cells.

Isoliquiritigenin (ISL), a flavonoid found in licorice, shallot, and bean sprouts, has been identified as a potent anti-tumor promoting agent. We previously demonstrated that ISL reduces cell proliferation and induces apoptosis in DU145 human prostate cancer cells and MAT-LyLu (MLL) rat prostate cancer cells. Overexpression of members of the ErbB receptor family is a frequently observed event in several human cancers, and ErbB receptors currently constitute the primary targets of anticancer strategies.

Activation of caspase-8 contributes to 3,3'-Diindolylmethane-induced apoptosis in colon cancer cells.

3,3'-Diindolylmethane (DIM) is the major in vivo product of acid-catalyzed oligomerization of indole-3-carbinol, which is a promising anticancer agent present in cruciferous vegetables and has itself been reported to have anticarcinogenic properties. This study examined DIM-mediated regulation of apoptosis in the HCT116 (wild-type p53) and HT-29 (mutant p53) human colon cancer cell lines. DIM (0-30 micromol/L) substantially decreased the number of viable cells and induced apoptosis of HCT116 and HT-29 cells in a concentration-dependent manner.
