Three new isoflavone glucosides, kudonol A-C (-), two new ester derivatives of phenylpropanoid, kudolignan A and B (-) and five known compounds, (-)-maackiain (), neoliquiritin (), methyl 4-coumarate (), methyl ferulate () and (+)-wikstromol (), were isolated from an extract of dried seeds of the traditional Chinese medicinal plant L. Their structures were established by NMR and HRESIMS data analyses. The monosaccharide part's configuration of isoflavone glucosides was confirmed by acid hydrolysis and analyzed by a JAsco OR-4090 chiral detector, comparing it to standard substance D-glucose. The cytotoxicity effects against HeLa, Hep3B, MCF-7 and H1299 cells were tested by CCK-8 assay.

Total Synthesis and Anti-Inflammatory Activity of Tectoridin and Related Isoflavone Glucosides.

J Nat Prod

December 2024

Anti-infective Agent Creation Engineering Research Centre of Sichuan Province, School of Pharmacy, Chengdu University, Chengdu 610106, China.

The first total syntheses of four isoflavone glucosides, tectoridin (), tectoridin A (), tectorigenin 7--β-d-glucopyranosyl-12--β-d-glucopyranoside (), and isotectroigenin 7--β-d-glucopyranoside (), have been accomplished. Key steps in our synthetic approach include a regioselective halogenation reaction, followed by methanolysis to introduce the -OCH group into isoflavone frameworks and a PTC-promoted stereoselective glycosidation to establish glycosidic bonds. The synthesized isoflavone glucosides (-) and their corresponding aglycones ( and ) were evaluated for anti-inflammatory activity against nitric oxide (NO), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1 β (IL-1β) in lipopolysaccharide (LPS)-induced RAW264.

Comparison of the Antioxidant Capacity of Cell Wall-Broken Decoction Pieces and Traditional Decoction Pieces of Astragli Radix Based on HPLC-ABTS Analytical Method.

Research Center of Chinese Herbal Resource Science and Engineering, School of Pharmaceutical Sciences, Guangzhou University of Chinese Medicine, Guangzhou, Guangdong, China.

Article Synopsis
  • - An online antioxidant assay using HPLC-ABTS was developed to evaluate flavonoids' antioxidant properties in Astragali Radix (AR) while comparing traditional decoction pieces (TDP) to cell wall-broken decoction pieces (CDP).
  • - The study found that CDP had about double the overall antioxidant capacity of TDP, with antioxidant levels from CDP being 1.9-5.1 times higher than those from TDP.
  • - Three specific antioxidants (calycosin-7-O-β-D-glucoside, calycosin, and formononetin) were identified, and the method created offers a reliable way to assess AR quality based on antioxidant activity. *

Article Synopsis
  • Mitochondrial phenotypes play a key role in understanding diseases and therapies, but their complex behavior requires detailed study at the single-cell level.
  • A new fluorescence analysis method using two-color and STED super-resolution imaging allows researchers to examine mitochondrial heterogeneity in glioma models from both humans and mice.
  • By simulating antitumor drug effects with rotenone and etoposide, this method provides insights into how mitochondrial changes correlate with apoptosis and helps visualize the impact of drugs on mitochondrial structure and function.

The traditional Chinese medicine (TCM) formula, gegen-huangqi (GH) decoction, has been employed for over 200 years, notably for its therapeutic effects in treating conditions such as atherosclerosis and diabetes mellitus. Despite its long-standing use, comprehensive studies on the chemical constituents of GH and their in vivo pharmacokinetics (PK) remain limited. This study aimed to profile the bioactive compounds present in GH decoction and to explore their PK characteristics using HPLC-Q-TOF-MS/MS.
