Cat. No.: HY-B0987 Purity: 99.61%
COA Handling Instructions

Ascorbyl palmitate is an orally active ester formed from ascorbic acid and palmitic acid, used as an antioxidant and food additive. Ascorbyl palmitate in preventing fat and oil oxidation is more efficient than Butylated hydroxyanisole (HY-B1066) and Butylated hydroxytoluene (HY-Y0172). Ascorbyl palmitate mitigates inhibition of collagen synthesis by select calcium and sodium channel blockers. Ascorbyl palmitate induces Apoptosis in human umbilical vein endothelial cells (HUVECs). Ascorbyl palmitate ameliorates inflammatory diseases by inhibition of NLRP3 inflammasome.

Description

Ascorbyl palmitate is an orally active ester formed from ascorbic acid and palmitic acid, used as an antioxidant and food additive. Ascorbyl palmitate in preventing fat and oil oxidation is more efficient than Butylated hydroxyanisole (HY-B1066) and Butylated hydroxytoluene (HY-Y0172). Ascorbyl palmitate mitigates inhibition of collagen synthesis by select calcium and sodium channel blockers. Ascorbyl palmitate induces Apoptosis in human umbilical vein endothelial cells (HUVECs). Ascorbyl palmitate ameliorates inflammatory diseases by inhibition of NLRP3 inflammasome[1][2][3][4].

In Vitro

Ascorbyl palmitate (25-400 μM, 24 h and 48 h) induces cell cytotoxicity and inhibits cell growth in HUVECs in a dose- and time-dependent manner[1].
Ascorbyl palmitate (125 μM, 24 h and 48 h) inhibits proliferation of HUVECs and induces cell death by inducing apoptosis, which decreases Bcl-2 gene expression ratio and increases Caspase-3, 9 activities in HUVECs[1].
Ascorbyl palmitate (1.25-20 μM, 72 h) dependent extracellular matrix (ECM) deposition of collagen type l is significantly reduced in aortic smooth muscle cells, which is inhibited by Nifedipine (HY-B0284) (50 µM, 72 h)[2].
Ascorbyl palmitate (0-20 μM, 1 h) has stronger inhibitory activity against NLRP3 inflammasome through its antioxidant ability than ascorbic acid in LPS (HY-D1056)-primed bone marrow-derived macrophages (BMDMs)[3].

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 (6.03 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.
