Biological Activity

Description Oseltamivir Phosphate(Tamiflu) is a potent and selective inhibitor of the neuraminidase that is essential for replication of influenza A and B viruses, used to prevent influenza.
Targets
Neuraminidase [1]
In vitro
In vitro

Oseltamivir Phosphate, anti-Neu1 antibodies, and matrix metalloproteinase-9-specific inhibitor blocks Neu1 activity associated with EGF-stimulated TNBC MDA-MB-231 cells[2]. Oseltamivir slows the spread of influenza (flu) virus between cells in the body by stopping the virus from chemically cutting ties with its host cell.
Cell Research Cell lines MDA-MB-231 cells/MCF-7 cells
Concentrations 500, 600, 700, 800 μg/mL
Incubation Time 24, 48, and 72 h 
Method

Cells are incubated in 96-well plates (5,000 cells/well) and allowed to adhere for 24 hours in 1× DMEM media containing 10% FCS. The media are replaced with fresh DMEM media containing 5% FCS with or without various concentrations of tamoxifen or OP for indicated time periods. Cell viability is tested using WST-1 cell proliferation assay.
In Vivo
In vivo

Oseltamivir Phosphate monotherapy may be the effective treatment therapy for TNBC(Triple-negative breast cancers)[2]. It is efficacious in treating infections caused by H5N1 and H9N2 influenza viruses in mice[3]. After dosing, the prodrug (Oseltamivir phosphate) is readily absorbed from the gastrointestinal tract and rapidly converted into the active metabolite, OC. In all patient groups, OC has high bioavailability and is systemically distributed to infection sites at concentrations sufficient to inhibit a range of influenza virus neuraminidases[4].

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.
