生物活性:
URAT1 inhibitor 2 is an orally active and potent URAT1 and CYP isozyme inhibitor, with IC50 values of 1.36 μM, 16.97 μM, 5.22 μM for URAT1-mediated 14C-UA uptake, CYP1A2 and CYP2C9, respectively. URAT1 inhibitor 2 is a promising agent candidate in the study of hyperuricemia and gout.

体内研究:
URAT1 inhibitor 2 (Intravenous at 2 mg/kg or orally at 10 mg/kg) has excellent pharmacokinetic properties with the oral bioavailability of 59.3%.URAT1 inhibitor 2 (4, 2, 1, 0.5, and 0.25 mg/kg; Orally) shows orally active and outstanding SUA-lowering activity with a dose-dependent manner in acute hyperuricemia mice.URAT1 inhibitor 2 (1000 mg/kg, intragastric administration, once) shows favorable safety profiles and no obvious acute toxicity.Pharmacokinetic Parameters of URAT1 inhibitor 2 in male Sprague-Dawley rats.parameterunit p.o. i.v.
