Customer Review

Based on 1 Customer Validation

Epaminurad (UR-1102) is an orally active, potent and selective URAT1 (urate transporter 1) inhibitor, with a K_i 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.

Showed good uricosuric and urate-lowering effects at 3 mg/kg, the lowest dose, which were comparable to those of benzbromarone at 100 mg/kg, the highest dose, with maximum efficacy.

Animal Model:

Tufted capuchin monkeys^[1]
Dosage:

0, 3, 10, and 30 mg/kg
Administration:

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: 2.5 mg/mL (6.04 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 2.5 mg/mL.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: 2.5 mg/mL (6.04 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 2.5 mg/mL.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: 2.5 mg/mL (6.04 mM); Clear solution; Need ultrasonic

This protocol yields a clear solution of 2.5 mg/mL. If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
