Epaminurad (UR-1102) is an orally active, potent and selective URAT1 (urate transporter 1) inhibitor, with a Ki of 0.057 μM. Epaminurad quite modestly inhibits OAT1 and OAT3 (organic anion transporter). Epaminurad is a uricosuric agent. Epaminurad can be used for gout and hyperuricemia research.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
