[Pharmacology and Toxicology] Glutathione is a tripeptide containing sulfhydryl (SH) that is widely found in nature. It is mainly found in the cytoplasm and plays a role in various cellular life functions. Glutathione is a cofactor of glyceraldehyde phosphate dehydrogenase, and a coenzyme of glyoxalase and triose phosphate dehydrogenase. It participates in the tricarboxylic acid cycle and sugar metabolism in the body. It can activate SH enzymes in the body and promote the metabolism of carbohydrates, fats and proteins. Glutathione can also combine with free radicals in the body through sulfhydryl groups to promote the formation of easily metabolized low-toxic compounds, so it has a detoxifying effect on some exogenous poisons.
[Pharmacokinetics] Mice reach the peak blood concentration in about 5 hours after intramuscular injection, and the t1/2 is about 24 hours. Data show that after intravenous injection of 35S-GSH in animals, GSH is well distributed in various organs in a very short time, especially in the liver, kidney, skin and spleen. Although the distribution of radioactivity per unit body weight in the heart, skeletal muscle and brain is not high, its elimination from these organs is also slow. Within seven days after injection, 24±4.2% of the radioactivity is excreted in the urine.
