生物活性

Rebamipide (OPC12759) is an orally active gastroprotective agent that enhances the production of endogenous PGs (especially intragastric PGE2) by inducing COX-2 expression, thereby protecting the gastric mucosa from injury. Rebamipide exerts anti-proliferative activity against gastric cancer cells. Rebamipide can be used in studies of mucosal protection, gastroduodenal ulcer, gastritis and gastric cancer.

体外研究(In Vitro)

Rebamipide (1.4, 2.7, 5.4 mM; 24 h) inhibits proliferation of gastric cancer cell.
Rebamipide (5.4 mM; 30 min) activates Smad signaling pathway in AGS cells.
Rebamipide (5.4 mM; 3 h) induces the expression of Cdk inhibitor p21 in AGS cells.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay

Cell Line: AGS cells
Concentration: 1.4, 2.7, 5.4 mM
Incubation Time: 24 h
Result: Significant decreased in cell proliferation in a concentration-dependent manner.

Western Blot Analysis

Cell Line: AGS cells
Concentration: 5.4 mM
Incubation Time: 30 min or 3 h
Result: Significantly increased phosphorylation of Smad2/3 by 1.2-fold when at 30 min and formation of Smad2/3-Smad4 complex by 1.4-fold.
Upregulated expression of p21 protein by 2.5-fold when at 3 h.
体内研究(In Vivo)

Rebamipide (5, 15, 50 mg/kg; p.o.; once daily for 14 days) enhances the expression of COX-2 and PGE2, and protects gastric mucosa from acid-induced injury in rat gastric mucosa.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Specific pathogen-free male Sprague-Dawley rats (200-230 g; 7-week-old).
Dosage: 5, 15, 50 mg/kg
Administration: Oral administration; once daily for 14 days.
Result: Increased the level of COX-2 immunoreactivity and PGE2 in a dose-dependent manner. (PGE2 is implicated in protection of gastric mucosa from various insults and acceleration of gastric wound healing).
Inhibited intragastric HCl administration-induced gastric mucosal bleeding and erosion.
