  4. Annonacin

Annonacin is an acetylgenin that is toxic by inhibiting the pathway of the mitochondrial complex. Annonacin increases tau phosphorylation in R406W+/+ mice. Annonacin acts as an inhibitor of the sodium/potassium and sarcoplasmic reticulum (SERCA) ATPase pumps. Annonacin has significant killing effect on ovarian cancer cell, cervical cancer cell, breast cancer cell, bladder cancer cell and skin cancer cell. Annonacin induces apoptosis through Bax and Caspase-3-related pathways.

Description

Annonacin is an acetylgenin that is toxic by inhibiting the pathway of the mitochondrial complex. Annonacin increases tau phosphorylation in R406W+/+ mice. Annonacin acts as an inhibitor of the sodium/potassium and sarcoplasmic reticulum (SERCA) ATPase pumps. Annonacin has significant killing effect on ovarian cancer cell, cervical cancer cell, breast cancer cell, bladder cancer cell and skin cancer cell. Annonacin induces apoptosis through Bax and Caspase-3-related pathways[1][2][3][4].

In Vitro

Annonacin (1-10 μg/mL; 0-72 h) induces the death of a variety of cancer cell lines, and blocks cancer cells in G1 phase [2].
Annonacin 10 μg/mL; 0-24 h) induces apoptosis of T24 cells and enhance the expression of pro-apoptosis-related genes [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 (4.19 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.
