AR420626 is a selective agonist of free fatty acid receptor 3 (FFAR3) (IC₅₀=117 nM). AR420626 has anti-inflammatory, anticancer and antidiabetic activities. AR420626 improves neurogenic diarrhea by inhibiting nAChR mediated neural pathways. AR420626 inhibits the growth of HepG2 xenografts and inhibits the proliferation of hepatoma cells by inducing apoptosis. AR420626 also suppresses allergic asthma and eczema and has the ability to activate GPR41 to increase Ca²⁺ signal-mediated glucose uptake and improve diabetes.

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 90% (20% SBE-β-CD in Saline)

Solubility: 2 mg/mL (4.79 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 2

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

Solubility: ≥ 2 mg/mL (4.79 mM); Clear solution

This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

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.
