Abstract A novel series of chalcone derivatives containing diaryl ether moiety (5a-5p) were designed, synthesized and evaluated their anti-tubulin polymerization activities and anticancer activities. Among them, compound 5b with 4-methoxy substitution on right aromatic ring was found to be most active on MCF-7, HepG2 and HCT116 cancer cell lines, with IC50 values of 3.44±0.19, 4.64±0.23, and 6.31±0.27 μM, respectively. In vitro tubulin polymerization assay showed that 5b could effectively inhibi...

: This study is to study the absorption properties of different particle size of Gastrodiae Rhizoma powder in rats. In vivo circulation pass perfusion model combined with ultra high performance liquid chromatography-mass spectrometry(UPLC-MS/MS) method was used to determine the cumulative absorption of each component in different particle size of Gastrodiae Rhizoma powder, and the effect of different particle size, different concentrations, different intestine segments and bile on the intestine ...

: This work aimed to investigate the intestinal absorption characteristics of Laportea bulbifera extract in normal and rheumatoid arthritis model rats. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, kaempferol-3-O-rutinoside, galuteolin, quercetin and isoquercetin in intestinal absorption solution samples were detected by UPLC-MS/MS with 5.0 g·L~(-1) as the absorption concentration. The cumulative absorption(Q) and absorption rate constant(K_a) were calcula...

Bletilla striata has been widely used as a valuable hemostatic agent for thousands of years due to the high levels of bioactive constituents it contains. Here, we used a sensitive ultrahigh-performance liquid chromatography-tandem mass spectroscopy (UPLC-MS/MS) method for the simultaneous determination of three major active ingredients of the B. striata extract, namely, α-isobutylmalic acid, gymnoside I, and militarine in rat plasma. The three major active ingredients were determined using the m...
