Tinoridine hydrochloride (Y-3642 hydrochloride)

Kinase experiment:

CCl4 aministration produces a marked decrease in the concentrations of liver microsomal cytochrome P-450 and G6Pase, indicating that hepatic endoplasmic reticulum function is disrupted. Prior treatment of the animals with tinoridine (100 mg/kg) significantly reduces the CCl4-induced alterations in the enzyme activities, and a rapid recovery toward the normal values is observed[2].

Animal experiment:

Rat: Male Wistar rats (180-220 g) are used in the experiments. Drugs (Tinoridine) are given orally as a suspension in 0.5% methylcellulose solution 1 hr before CCl4, administration. Control animals receive an equivalent amount of the vehicle. CCl4 is administered ip at a dose of 0.25 ml/kg as a 5% (v/v) solution in olive oil. The animals are killed by carotid excision at different times after CCl4 administration; the livers are rapidly removed, weighed and processed for biochemical or histologic analysis[2].
