Description

Meisoindigo (Dian III), a derivative of Indirubin (HY-N0117), halts the cell cycle at the G0/G1 phase and induces apoptosis in primary acute myeloid leukemia (AML) cells. Meisoindigo exhibits high antitumor activity[1][2].

In Vitro

Meisoindigo (Dian III; 5-20 μM; for 24 hours) inhibits growth of the AML cell lines[1].
Meisoindigo (10 μM; for 24 hours) induces apoptosis of acute myeloid leukemia[1].
Meisoindigo (5-10 μM; for 24 hours) causes cell-cycle arrest[1].
Meisoindigo (5-10 μM; for 24 hours) increases the cleaved caspase-3 and pro-apoptotic Bak, and decreases Bcl-2 and Bcl-xL levels in HL-60 cells[1].
Meisoindigo (10, 30, 50, 100, 150 μM; 24 hours) interdicts LPS-induced (1 μg/mL) NLRP3 inflammasome activation and M1/M2 polarization through down-regulation of TLR4 pathways after OGD/R in HT-22 and BV2 cells[2].

Western Blot Analysis[1]

Cell Line: HL-60 cells
Concentration: 5, 10 μM
Incubation Time: For 24 hours

In Vivo

Meisoindigo (Dian III; 50-150 mg/kg; IP; daily; for 14 days) has anti-leukemic activity in vivo[1].
Meisoindigo (2, 4, 8, 12 mg/kg; IP; before MCAO and 2 h after reperfusion) significantly reduces infarct volume, ameliorates neurological deficits 3 days after middle cerebral artery occlusion (MCAO) in Wild-type C57BL/6J mice (25-30 g). Meisoindigo reduces edema and lowers AQP4 expression in the brain[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: ≥ 2.5 mg/mL (9.05 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.
