Biological Activity

Description Voreloxin hydrochloride (SNS-595, Vosaroxin) is a potent Topoisomerase II inhibitor with broad-spectrum anti-tumor activity. Phase 2.
Targets
Topo II [1]
In vitro
In vitro Voreloxin exhibits potent inhibitory effect in topoisomerase II relaxation with IC50 of 3.2 μg /mL without effect on topoisomerase II cleavage. Voreloxin has a cytotoxic activity against human tumor cell lines more potent than that of etoposide. [1] Voreloxin has broad anti-proliferative activity in 15 cell lines, including 4 drug-resistant lines, with IC50 ranging from 0.04 to 1.155 μM. [2]
Cell Research Cell lines P388 leukemia cells
Concentrations ~10 μg/mL
Incubation Time 72 hours
Method Cells are put into wells of a 96-well microtiter plate in the amount of 0.1 mL/well, preincubated for 24 h except for P388 cells, and incubated with various concentrations of a test compound in the 5% CO2 incubator at 37 ° for 72 h. After the culturing, 0.02 mL of a MTT solution (5 mg/mL) is put in each well, and the cells are cultured for a further 4 h. The medium is removed by suction, and 0.2 mL of DMSO is put in each well to dissolve the formed formazan. The absorbance is measured by Multiskan Bichromatic. The IC50 is defined as the drug concentration needed to produce a 50% reduction of absorbance relative to the control.
In Vivo
In vivo Voreloxin (50 mg/kg i.p.) shows potent in vivo antitumor activity mice implanted with P388 leukemia cells. [1] Voreloxin (25 mg/kg i.v.) demonstrates strong tumor growth inhibition in 10 of 11 solid tumor (breast, ovarian, colon, lung, gastric, and melanoma) xenograft models, 2 hematologic tumor xenograft models, 3 multidrug resistant tumor models and 3 murine syngeneic tumor models (Colon 26, Lewis Lung carcinoma, M5076 Ovarian Sarcoma).

Animal Research Animal Models Mice implanted with P388 leukemia cells.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
