Biochem/physiol Actions

Anti-ulcer drug that stimulates gastric mucin secretion
Gefarnate is an anti-ulcer drug that stimulates gastric mucin secretion. Also gefarnate increase secretion of mucin-like glycoprotein in rabbit conjunctival tissue. It appears to be effective in animal dry-eye models. It is approved in Japan, where it is used to treat gastritis and gastric ulcer. Gefarnate is structurally similar to anti-ulcer drug teprenone (geranyl farnesylacetate), which induces expression of HSP70, HSPB8, and HSPB1.

We have reported that teprenone (geranylgeranylacetone), an anti-ulcer drug, prevents acute gastric mucosal lesion progression in rats treated once with compound 48/80 (C48/80), a mast cell degranulator, possibly by suppressing mucus depletion, neutrophil infiltration, and oxidative stress in the gastric
