HIDE SMILES / InChI
Sulfobromophthalein (BSP) is a dye with a high affinity for organic anion transporting polypeptides (OATPs) and has been used as a substrate for multidrug resistance associated protein 2 (Mrp2). BSP is transported into hepatocytes by OATPs and, after conjugation to glutathione, is excreted into bile by Mrp2.3 It was found to inhibit the aldo-keto reductase ARK1C20. Sulfobromophthalein (BSP) is used in diagnosis of hepatic disorders.It is also used for the quantitative determination of proteins.

Originator

Curator's Comment: Sulfobromophthalein sodium (BSP, Bromsulphalein) has been used extensively for testing hepatic function since its introduction by Rosenthal and White in 1925

Sample Use Guides

Rats: 350mg/day, i.v.
Route of Administration: Intravenous
In Vitro Use Guide
In competitive binding studies in vitro between Sulfobromophthalein (BSP) and a series of organic anions (sodium fluorescein, indocyanine green, bilirubin, sodium taurocholate, flavaspidic acid glucaminate, and iodipamide methylglucamine), the incubation mixture contained 500 ug of BSP and equimolar amounts of the aforementional organic anions. On the average, 160 +/- 2 ug BSP was bound per mg of membrane protein and 1.4 +/-0.1 ug BSP bound per unit of Co++-CMPase activity in 15 membrane isolates. BSP binding was maximal at 500 ug BSP/ml in the incubation mix with proportionately less binding observed at lower concentrations. BSP concentrations above 500 ug/ml reduced BSP binding and produced dissolution of cell membranes.
