In Vitro

Peimine (0-200 μM, 24 h) disrupts intracellular calcium homeostasis through the Ca2+/CaMKII/JNK pathway, inhibits the growth and movement of prostate cancer cells (DU-145, LNCap, and PC-3) and induces apoptosis, while having no significant effect on normal cells (RWPE-1) [3].
Peimine (0-25 mg/L, 1 h) has anti-inflammatory activity through regulating TNF-a, IL-6, IL-1b and IL-10 by suppressing the phosphorylation of MAPK and the activation of NF-kB in LPS-stimulated RAW 264.7 macrophages[6].
Peimine (10-300 μM, 0-10 ms) can block the Nav1.7 ion channel with an IC50 value of 47.2 μM, and can also inhibit the Kv1.3 ion channel with an IC50 value of 354.4 μM[7].

Western Blot Analysis[3]

Cell Line: PC-3 cells
Concentration: 0-10 μM
Incubation Time: 24 h
Result: Decreased the protein expression levels of Ki-67 and PCNA in PC-3 cells in a dose-dependent manner.
In Vivo

Peimine (32.5 μM/kg/day for 7days,i.g.) can effectively alleviate LPS-induced acute lung injury in mice, inhibit the expression levels of inflammatory factors TNF-α, IL-6, and IL-1 in mouse models, and has a synergistic effect when combined with Peiminine (HY-N0213) and Forsythoside. It can effectively improve its anti-inflammatory activity[4].
The drug level of Peimine (single oral 4.25 g/kg) in the blood and tissue of male rats is significantly higher than that of female rats (Reference 3)[5].

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: ≥ 2.5 mg/mL (5.79 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.

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.
