Description

Application

Sulfobromophthalein disodium salt hydrate has been used as a positive control to study the interaction of 11-keto-β-boswellic acid (KBA) and 3-acetyl-11-keto-β-boswellic acid (AKBA) with organic anion transporter OATP1B3.

Biochem/physiol Actions

Sulfobromophthalein (BSP) is a high affinity organic ion substrate 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. It was found to inhibit the aldo-keto reductase ARK1C20.
