The salinomycin inhibited the growth of CNE-2 in time- and dose-dependent manner. SAL salinomycin
Tumour Biol, 2016, 305-11. Salinomycin (from Streptomyces albus) purchased from Selleck.
Drug sensitivity of KPC tumor cell subpopulations. CD133, Aldefluor, and Sca-1-positive or -negative cells or unsorted KPC cells were cultured in the presence of increasing concentrations of salinomycin. After 72 hours, cell viability was assessed using CellTiter Glo reagent, and percent viability was normalized to vehicle-treated controls. Pair-wise multiple comparisons were performed with one-way ANOVA with Bonferroni adjustment. P values < 0.05 were considered statistically significant.

|Description||Salinomycin, traditionally used as an anti-coccidial drug, has recently been shown to possess anti-cancer and anti-cancer stem cell (CSC) effects.|
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.
|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.|

* 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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
