|Description||Tiopronin is an antioxidant agent, used for the treatment of cystinuria by controlling the rate of cystine precipitation and excretion.|
Tiopronin is an antioxidant with a free thiol (sulfidryl) group that has been shown to protect against cisplatin nephrotoxicity both in vitro and in vivo. Tiopronin improves the defence of the cochlea and scavenge the reactive oxygen species, whereas vitamin E (a-tocopherol) and vitamin C act by inhibiting lipid peroxidation and preventing free radical formation.  Tiopronin (2 mM) completely prevents the Cisplatin-induced increase in enzyme leakage and substantially blocks the decrease of MTT reduction caused by Cisplatin. Tiopronin also significantly protects the renal slices from cisplatin-induced toxic effects. Tiopronin protects against cisplatin-induced nephrotoxicity by acting as an alternative target for Cisplatin both intra- and extracellularly and thus protects against cisplatin-induced depletion of glutathione in the kidney cell.  Tiopronin protects rat kidney slices in vitro from the nephrotoxic effects of Cisplatin and does not reduce the antitumour activity of Cisplatin. Tiopronin provides marked protection againstcisplatin-induced increases in urea and creatinine.  Tiopronin protects against Cisplatin-induced changes in the adenine nucleotides in rat renal cortical slices. 
|In vivo||Tiopronin significantly lowers both the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, while only the serum ALT level is lowered by ursodeoxycholic acid (UDCA) in rats. Tiopronin significantly decreases the serum and liver levels of triglyceride (TG), total cholesterol (TC) and free fatty acids (FFA) as well as the serum LDL-C level, and increases the serum HDL-C level. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
