Abstract

Aim and objective

Two structurally related flavonoids found in Cyclopia subternata, namely vicenin-2 and scolymoside, were examined for its effects on inflammatory responses by monitoring the effects of vicenin-2 and scolymoside on lipopolysaccharide (LPS)-mediated vascular inflammatory responses.

Methods

The anti-inflammatory activities of vicenin-2 and scolymoside were determined by measuring permeability, monocytes adhesion and migration, and activation of pro-inflammatory proteins in LPS-activated HUVECs and mice.

Results

We found that post-treatment of each compound inhibited LPS-induced barrier disruption, expression of cell adhesion molecules (CAMs), and adhesion/transendothelial migration of human neutrophils to human endothelial cells. Each compound induced potent inhibition of phorbol-12-myristate 13-acetate (PMA) and LPS-induced endothelial cell protein C receptor (EPCR) shedding. It also suppressed LPS-induced hyperpermeability and leukocytes migration in vivo. Furthermore, each compound suppressed the production of tumor necrosis factor-α (TNF-α) or Interleukin (IL)-6 and the activation of nuclear factor-κB (NF-κB) or extracellular regulated kinases (ERK) 1/2 by LPS. Moreover, post-treatment with each compound resulted in reduced LPS-induced lethal endotoxemia.

Conclusion

Vicenin-2 and scolymoside possess anti-inflammatory functions by inhibiting hyperpermeability, expression of CAMs, and adhesion and migration of leukocytes, thereby endorsing its usefulness as a therapy for vascular inflammatory diseases.

Herzinfarkt mit 85 – trotzdem noch intensive Lipidsenkung?

16.05.2024 Hypercholesterinämie Nachrichten

Profitieren nach einem akuten Myokardinfarkt auch Betroffene über 80 Jahre noch von einer intensiven Lipidsenkung zur Sekundärprävention? Um diese Frage zu beantworten, wurden jetzt Registerdaten aus Frankreich ausgewertet.

CKD bei Diabetes: Neuheiten und Zukunftsaussichten

16.05.2024 DDG-Jahrestagung 2024 Kongressbericht

Jeder Mensch mit Diabetes muss auf eine chronische Nierenerkrankung gescreent werden – diese neue Empfehlung spricht die KDIGO aus. Die Therapie erfolgt individuell und je nach Szenario mit verschiedenen Substanzklassen. Künftig kommt wahrscheinlich, neben RAS-Hemmung, SGLT2-Inhibition und nsMRA, eine vierte Therapiesäule hinzu.
