Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Salinomycin, traditionally used as an anti-coccidial drug, has recently been shown to possess anti-cancer and anti-cancer stem cell (CSC) effects.
Targets
Wnt/β-catenin [1]
In vitro Salinomycin, a polyether ionophore antibiotic isolated from Streptomyces albus, has been shown to kill CSCs in different types of human cancers, most likely by interfering with ABC(ATP-binding cassette) drug transporters, the Wnt/β-catenin signaling pathway, and other CSC pathways. Salinomycin exhibits antimicrobial activity against Gram-positive bacteria including Bacillus subtilis, Staphylococcus aureus, Micrococcus flavus, Sarcina lutea, Mycobacterium spp., some filamentous fungi, Plasmodium falciparum, and Eimeria spp., protozoan parasites responsible for the poultry disease coccidiosis. In addition, salinomycin has early been shown to act in different biological membranes, including cytoplasmic and mitochondrial membranes, as a monovalent cation ionophore with strict selectivity for alkali ions and a strong preference for K+, thereby promoting mitochondrial and cytoplasmic K+ efflux and inhibiting oxidative phosphorylation. Salinomycin can induce massive apoptosis in human cancer cells of different origin that display multiple mechanisms of drug and apoptosis resistance[1].
In vivo Salinomycin is able to effectively eliminate CSCs and to induce partial clinical regression of heavily pretreated and therapy-resistant cancers. It has also been demonstrated as a positive ionotropic and chronotropic agent that increased cardiac output, left ventricular systolic pressure, heart rate, mean arterial pressure, coronary artery vasodilatation and blood flow, and plasma catecholamine concentration. These results have been obtained in experiments with mongrel dogs that has received a single intravenous injection of 150 μg/kg salinomycin. However, It has been reported with a considerable toxicity of salinomycin in mammals, such as horses, pigs, cats, and alpacas after accidental oral or inhalative intake. Risk assessment data recently published by the European Food Safety Authority declare an acceptable daily intake (ADI) of 5 μg/kg salinomycin for humans, because daily intake of more than 500 μg/kg salinomycin by dogs leads to neurotoxic effects, such as myelin loss and axonal degeneration. Intravenous administration of 200-250 μg/kg salinomycin every second day for three weeks results in partial regression of tumor metastasis and shows only minor acute and long-term side effects, but no severe acute and long-term side effects observed with conventional chemotherapeutic drugs[1].

Protocol (from reference)

Cell Assay:

[2]
  • Cell lines

    colon cancer (SW480, SW620, RKO) and breast cancer cell lines (MCF-7, T47D, MDA-MB-453).

  • Concentrations

    1, 2.5, 5, 10 μM

  • Incubation Time

    26 h

  • Method

    Cells are plated at 1500 (SW480 or SW620) or 4000 (all other cell lines) per well in flat-bottom 96-well plates. They are treated with salinomycin at the indicated concentration 16 hours later. Seventy-two hours after this, 5 mg/ml MTT in PBS is added per well; cells are lysed after 4 hours by addition of 50 µl triplex solution (10% SDS; 5% isobutanol, 0.012 M HCl). Absorbance is measured at 562 nm. Alternatively, viability is determined with the ViaCount reagent on a Guava easyCyte8HT flow cytometer, following the instructions of the manufacturer.
Animal Study:

  • Animal Models

    NOD/SCID mice

  • Dosages

    5 mg/kg

  • Administration
