Protective effect of 4-(3,7,11,15-tetramethyl-6,10,14-hexadecatrienoyl)morpholine on liver injury induced by hepatotoxins in rats.
The effect of 4-(3,7,11,15-tetramethyl-6,10,14-hexadecatrienoyl)morpholine (E-0712), a new synthetic compound, on liver injury induced by two hepatotoxins in rats was studied. Oral doses of E-0712 four times at 0, 6, 12 and 18 hr significantly attenuated elevated SGPT values and prolonged prothrombin time (PT) at 24, 36, 48, 60 and 72 hr in rats with a single s.c. dose of D-galactosamine in which SGPT values and PT reached the peak within 48 hr. In cases in which a dose of carbon tetrachloride (i.p.) produced peak SGPT values and PT within 36 hr attenuation occurred likewise at 24, 36 and 60 hr. In the control and E-0712-treated rats dosed with D-galactosamine or carbon tetrachloride, SGPT values were positively correlated with PT at 24 hr. In addition, morphological degrees of acidophilic body formation or centrizonal necrosis were significantly reduced by E-0712. These results suggest that E-0712 protects against liver injury, particularly hepatocellular necrosis, induced by D-galactosamine and carbon tetrachloride in rats.
