2-(E-2-decenoylamino)ethyl 2-(cyclohexylethyl) sulfide (compd.III-1α, 100 mg/kg, p.o.) maintains the relative content of Fr.I hexose, lipid peroxide and phospholipase A2 (PLA2) in normal level in ulcerated rats induced by water immersed restrained stress via dosing twice a day for 3 day (b.i.d. for 3 d). 2-(E-2-decenoylamino)ethyl 2-(cyclohexylethyl) sulfide (100 mg/kg, p.o.) reduces the hexosamine content equally with the control group 4 h after the stress loading, and then markedly increases 7 h after stress loading. 2-(E-2-decenoylamino)ethyl 2-(cyclohexylethyl) sulfide (25 mg/kg, p.o.) blocks the reduction of prostaglandin E2 (PGE2) and PGI2 in early phase and accelerates the increase of PGE2 and PGI2 in the late phase of the stress. 2-(E-2-decenoylamino)ethyl 2-(cyclohexylethyl) sulfide (25 mg/kg, p.o.) also significantly accelerates the cell proliferation in fundic glands in gastric mucosa of mice[1].
