The method for the chiral analysis of (−)-yatein was developed and the distribution of this component in the plants of three genera likeJuniperus, Thuja andChamaecyparis belonging to Cupressaceae family was examined. The chiral analysis of (−)-yatein from the plants was carried out by high performance liquid chromatography on (R,R)-Whelk-O1 column using 81 v/v% methanol as mobile phase. The yatein...... hiện toàn bộ

Low level impurities often reside in cosmetic products. The aim of the present study was to estimate the human exposure to chromium from cosmetic products purchased at a local market in South Korea, and to assess the risk on public health. Hexavalent chromium is an impurity substance that contaminates cosmetic products during manufacture. The potential for chromium to induce and elicit allergic co...... hiện toàn bộ
Facile synthesis and biological evaluation of heterocyclic compounds containing DiazepamArchives of Pharmacal Research - Tập 24 - Trang 263-269 - 2001
M. A. Berghot
Diazepamoxadiazoles4,5,6,12,14 and22 were prepared with the binary form system. Diazepamthiadiazoles15,20 and Diazepamtriazoles7,8,9,17,18,19 and21 were also shapely synthesized. Some of these compounds were screened to test their antibacterial activity againstE. coli andB. subtilis compounds 15 and 20 show potent activity against these bacteria.

Bromination of 2,3-diphenyl-5-methylindole (I) (using 3 mol) with bromine gave the 4,6-dibromo derivative (II) which upon oxidation gave the corresponding 2-benzamido benzophenone derivative (III). Bromination (using 6 mol) with bromine afforded the tetrabromo derivative (IVa) which reated with amines to form the corresponding 5-substituted aminomethyl derivatives (IVb-d). Further bromination ofII...... hiện toàn bộ

Three naphthopyrone glucosides, cassiaside (1), rubrofusarin-6-O-β-D-gentiobioside (2), and toralactone-9-O-β-D-gentiobioside (3), were isolated from the BuOH-soluble extract of the seeds ofCassia tora as active constituents, using an,in vitro bioassay based on the inhibition of advanced glycation end products (AGEs) to monitor chromatographic fractionation. The structures of1–3 were determined by...... hiện toàn bộ
Chemopreventive effect of protein extract ofAsterina pectinifera in HT-29 human colon adenocarcinoma cellsArchives of Pharmacal Research - Tập 29 - Trang 209-212 - 2006
Yun-Hee Shon, Kyung-Soo Nam
We investigated the effect of protein extract ofAsterina pectinifera on the activity of 4 enzymes that may play a role in adenocarcinoma of the colon: quinone reductase (QR), glutathioneS-transferase (GST), ornithine decarboxylase (ODC), and cyclooxygenase (COX)-2. QR and GST activity increased in HT-29 human colon adenocarcinoma cells increased that had been exposed to 4 concentrations of the pro...... hiện toàn bộ
