title: Effects of 8-(2-dimethylaminoethyl)-3-oxo-4-phenyl-1-thia-4,8-diazaspiro [4,5] decane dihydrochloride monohydrate (Y-8845) on carbon tetrachloride-induced liver injury.
abstract: The effects of 8-(2-dimethylaminoethyl)-3-oxo-4-phenyl-1-thia-4,8-diazaspiro [4, 5] decane dihydrochloride monohydrate (Y-8845) on carbon tetrachloride (CCl4)-induced liver injury were investigated in rats. CCl4-induced attenuation of the plasma cyclic AMP (cAMP) response to glucagon stimulation was significantly prevented by pretreatment with Y-8845. Y-8845 also effectively suppressed the increases in the activities of serum transaminases as well as the decreases in microsomal glucose-6-phosphatase activity and microsomal cytochrome P-450 concentrations induced by CCl4. In rats at 72 hr after CCl4 administration, the plasma cAMP response to glucagon, microsomal glucose-6-phosphatase activity and P-450 concentration were all below the control level. Y-8845 treatment after CCl4 administration rectified these reductions to nearly normal levels. Furthermore, Y-8845 stimulated DNA synthesis during liver regeneration after CCl4 intoxication. These results demonstrate that Y-8845 has a protective effect against CCl4-induced injury in the liver and a stimulating effect on the recovery of the damaged liver.
