Description

Pachymic acid is a lanostrane-type triterpenoid from P. cocos. Pachymic acid inhibits Akt and ERK signaling pathways.

IC50 & Target[1]

ERK

 

In Vitro

Pachymic acid (PA) is able to inhibit gallbladder cancer tumorigenesis involving affection of Akt and ERK signaling pathways. Pachymic acid (PA) treatment significantly inhibits Rho A, Akt and ERK pathway in gallbladder carcinoma cells. Pachymic acid (PA) treatment can dose-dependently downregulate PCNA, ICAM-1, RhoA, p-Akt and pERK. Cell growth is inhibited by 10 µg/mL Pachymic acid (PA) 12 h after treatment, and a concentration of 30 µg/mL further reduced cell growth. The growth of cells is suppressed in a time- and dose-dependent manner. After 48 h treatment, about 25%, 40% and 70% of the cell growth are inhibited by Pachymic acid (PA) at concentration of 10 µg/mL, 20 µg/mL and 30 µg/mL, respectively. Pachymic acid (PA) also inhibits the growth of gallbladder carcinoma cells in a time-dependent and dose-dependent manner[1].

In Vivo

To evaluate the anti-tumor activity of Pachymic acid (PA) in vivo, human lung cancer NCI-H23 tumor xenograft models are used. Pachymic acid (PA) significantly suppresses tumor growth at doses of 30 and 60 mg/kg for 21 days compared with the control group[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: 1 mg/mL (1.89 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 1 mg/mL (1.89 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 1 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 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.

Cell Assay
[1]

The antiproliferative effect of Pachymic acid (PA) on GBC-SD cells is evaluated using a cell counting kit-8 (CCK-8). Briefly, after indicated treatment, 10 µL of CCK-8 solution is added into each well, and following one hincubation, absorbance is measured at 450 nm using a microplate reader[1].

Animal Administration
[2]

Mice[2]
Female athymic nude mice of 4-5 weeks of age are used. Exponentially growing NCI-H23 cells (5×106 in 100 µL PBS) are injected subcutaneously in the right flank of each mouse. Tumor xenografts are allowed to grow to an average size of 100-200 mm3 and are randomly assigned to four different treatment groups (six mice per group): (a) vehicle control (0.1% DMSO in physiological saline); (b) Pachymic acid (PA) 10 mg/kg; (c) PA 30 mg/kg; (Dd) PA 60 mg/kg. The mice are administered PA via intraperitoneal (ip) injections for 3 weeks (5 days/week). Tumor size is measured on two axes with the aid of Vernier calipers and tumor volume (mm3) is calculated.

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.
