Avenanthramide A
Based on 1 Customer Validation
Avenanthramide A is an orally active phytoalexin that targets the RNA helicase DDX3 with a KD of 8.8 μM. Avenanthramide A induces mitochondrial swelling and increased ROS production, and triggers apoptosis in CRC cells. Avenanthramide A inhibits smooth muscle cell proliferation and enhances nitric oxide production. Avenanthramide A can be used in research on colorectal cancer and atherosclerosis.

Actividad biológica

Helicase |
Avenanthramide A binds most tightly to the ATP-binding domain-containing truncated DDX31-306 mutant (Kd = 7.11 μM), with weaker binding to the N-terminal DDX31-215 (Kd = 13.85 μM) and C-terminal DDX3307-662 (Kd = 36.25 μM) mutants[1].
Avenanthramide A (30 μM) potently inhibits the ATPase activity of purified recombinant human DDX3 protein[1].
Avenanthramide A selectively reduces the viability of human DLD1 colorectal cancer cells while having minimal effect on normal human FHC colonic epithelial cells[1].
Avenanthramide A (30 μM; 24 h) has reduced ability to suppress viability of human DLD1 colorectal cancer cells expressing DDX3R287A or DDX3R294A mutants, indicating these residues are critical for its anti-tumor activity[1].
Avenanthramide A (30 μM) downregulates NDUFS2 and UQCRC1 expression in human DLD1 colorectal cancer cells expressing wild-type DDX3, DDX3K255A, or DDX3S290A, but not in cells expressing DDX3R287A or DDX3R294A[1].
Avenanthramide A (30 μM) induces ROS production in human DLD1 colorectal cancer cells expressing wild-type DDX3, DDX3K255A, or DDX3S290A, but not in cells expressing DDX3R287A or DDX3R294A[1].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (8.35 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 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.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (8.35 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.
