Lesinurad OAT inhibitor

Cat.No.S4640

Lesinurad (RDEA-594) is a selective uric acid reabsorption inhibitor (SURI) under investigation for treatment of gout in combination with xanthine oxidase inhibitors. This compound is a URAT1 and OAT inhibitor, and is determined to be a substrate for the kidney transporters OAT1 and OAT3 with Km values of 0.85 and 2 µM, respectively.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC50/Ki
URAT1 [1]
In vitro

Lesinurad inhibits the uric acid transport activity of human URAT1 (hURAT1) at a 20-fold higher potency compared to rat URAT1 (rURAT1), with IC50's of 3.36 and 74.84 μM, respectively. This compound inhibits hURAT1 through an interaction that involves a critical residue, Phe365[1].
