Description

Splitomicin (Splitomycin) is a selective Sir2p inhibitor. Splitomicin inhibits NAD+-dependent HDAC activity of Sir2 protein. Splitomicin induces dose-dependent inhibition of HDAC in the yeast extract with an IC50 of 60 μM[1].

IC50 & Target[1]

Sir2p

60 μM (IC50)

In Vitro

Splitomicin (10-333 μM; 24 hours) elicits antiproliferative effects in MCF-7 and H1299 cells in a dose-dependent manner in colony formation assay. Splitomicin (33 μM) fails to decrease the number of colonies, but Splitomicin (100 and 333 μM) effectively inhibits colony formation in MCF-7 and H1299 cells[2].

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

Cell Proliferation Assay[2]

Cell Line: Human breast cancer MCF-7 and lung cancer H1299 cells
Concentration: 10, 33, 100, and 333 μM
Incubation Time: 24 hours
Result: Inhibited colony formation in a dose-dependent manner.
In Vivo

Splitomicin (80 mg/kg with an intraperitoneal injection every 24 h for 5 days, in mice) enhances tissue factor (TF) activity in the arterial vessel wall and accelerates carotid artery thrombus formation in a photochemical injury model[3].

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

Animal Model: C57BL/6 mice aged 12-14 weeks weighing on average 27 g[3]
Dosage: 80 mg/kg
Administration: Intraperitoneal injection every 24 h for 5 days
Result: Increased TF activity in mouse carotid artery as compared with the controls.

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: ≥ 2.08 mg/mL (10.49 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (10.49 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

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.
