Description

AMG7703 is a selective and allosteric agonists of FFA2 (GPR43), the receptor for short-chain fatty acids (SCFAs), acetate, and propionate. AMG7703 can be used to research for in inflammatory and metabolic[1].

In Vitro

AMG7703 (phenylacetamide 1) (30 μM) shows selectivity on FFA2 (GPR43) over FFA1 (GPR40) and FFA3 (GPR41) with in Chinese hamster ovary cells[1].
AMG7703 (0.041, 0.123, 0.37, 1.11 μM) acts as an FFA2 allosteric agonist, activates Gαi coupled signaling pathway[1].
AMG7703 (1, 3, 10, 30 μM) results in Gαi-dependent inhibition of lipolysis in adipocytes (3T3L1)[1].
AMG7703 (0.041, 0.123, 0.37, 1.11 μM) exhibits allosteric activity and inhibits Gαi-coupled cAMP with IC50 values of 0.7 μM (hFFA2) and 0.96 μM (mFFA2), respectively; as for Gαq-coupled aequorin inhibition, with EC50s of 0.45 μM (hFFA2) and 1.27 μM (mFFA2), respectively[1].
AMG7703 (0-1 μM) shows the positive cooperating effect of acetate and stimulates calcium mobilization in a concentration-dependent manner in CHO cell stably expressing hFFA2 and aequorin[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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: ≥ 2.5 mg/mL (8.48 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    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.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (8.48 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). 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
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
