Atraric acid (Methyl atrarate) is a specific androgen receptor (AR) antagonist with anti-inflammatory and anticancer effects. Atraric acid represses the expression of the endogenous prostate specific antigen gene in both LNCaP and C4-2 cells. Atraric acid can also inhibit the synthesis of NO and cytokine, and suppress the MAPK-NFκB signaling pathway. Atraric acid can be used to research prostate diseases and inflammatory diseases.

Description

Atraric acid (Methyl atrarate) is a specific androgen receptor (AR) antagonist with anti-inflammatory and anticancer effects. Atraric acid represses the expression of the endogenous prostate specific antigen gene in both LNCaP and C4-2 cells. Atraric acid can also inhibit the synthesis of NO and cytokine, and suppress the MAPK-NFκB signaling pathway. Atraric acid can be used to research prostate diseases and inflammatory diseases[1][2].

IC50 & Target

Androgen receptor, NO synthesis, MAPK-NFκB pathway[1][2]
In Vitro

Atraric acid (10 μM; CV1 cells) represses the transactivation function mediated by Dihydrotestosterone-induced human AR[1].
Atraric acid (10 μM; PCa cells) inhibits the expression of the PSA gene in both androgen-dependent and androgen-independent PCa cells[1].
Atraric acid (1-300 μM; 24 h) dose-dependently inhibits pro-inflammatory cytokine, nitric oxide, prostaglandin E2 in LPS-stimulated RAW264.7 cells, but does not influence the cell viability[2].
Atraric acid (100 and 300 μM; 18 h or 4 h) downregulates the expression of phosphorylated IκB, extracellular signal-regulated kinases (ERK) and nuclear factor kappa B (NFκB) signaling pathway to exhibit anti-inflammatory effects in LPS-stimulated RAW264.7 cells[2].

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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (12.74 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.
