Description

9-Hydroxyoctadecanoic acid (9-HSA) is an HDAC1 inhibitor that inhibits ∼66.4% HDAC1 enzymatic activity at 5 μM. 9-Hydroxyoctadecanoic acid shows anticancer activity[1].

IC50 & Target[1]

HDAC1

 

In Vitro

9-Hydroxyoctadecanoic acid (9-HSA) can bind to the active site of the three-dimensional model of the human HDAC1 protein[1].
9-Hydroxyoctadecanoic acid (9-HSA) (100 μM; 24 h) inhibits HT29 cell proliferation, induces arrest in G0/G1, and increases p21WAF1 expression both at the transcriptional and the translational levels[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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 (8.32 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.
