Study of acute oral toxicity of the thiazole derivative N-(1-methyl-2-methyl-pyridine)-N-(p-bromophenylthiazol-2-yl)-hydrazine in a Syrian hamster
The thiazole derivative N-1-methyl-2-methyl-pyridine)-N-(p-bromophenylthiazol-2-yl)-hydrazine was used to evaluate the acute oral toxicity in Syrian hamsters. The concentration of the doses (300 mg/kg and 2000 mg/kg) were based on the Class Acute Toxicity Method displayed in the OECD-423 guide. In addition, renal and liver biochemical tests were performed, as well as histopathological analysis. Our results showed that the compound’s lethal dose (LD50) was 1000 mg/kg and classified as category 4 according to the criteria adopted in the experiment’s protocol. Biochemical analysis of the liver function’s parameters showed that the LD50 values in all animals were higher than the reference values. However, the analyze of the kidney injury parameters showed an increase in the urea’s dosage but a decrease in the albumin’s dosage in all animals when compared to the reference values. Kidney biochemical analysis also showed that creatinine’s level was only higher than the reference values in one animal. Massive damages in the liver were observed, such as hypertrophy and hyperplasia of the hepatocyte, coagulation necrosis, the presence of mononuclear cells in the sinusoidal capillaries, steatosis, cholestasis, and congestion of sinusoidal capillaries and central-lobular veins. The animals presented renal injuries related to congestion of glomerular and interstitial capillaries, nephrosis of contorted proximal and distal tubules and congestion in the medullary region. In conclusion, the thiazole derivative was well tolerated although it caused acute liver and kidney damages. Therefore, these results showed the need of further investigation of this compound in vivo to evaluate the potential therapeutic effects with chronic models.
Electric Literature of 143468-13-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 143468-13-7 is helpful to your research.
