|Description||Cabotegravir (GSK744, GSK1265744, S/GSK1265744) is a long-acting HIV integrase inhibitor against a broad range of HIV subtypes, and inhibits the HIV-1 integrase catalyzed strand transfer reaction with IC50 of 3.0 nM. Phase 2.|
GSK1265744 inhibits HIV replication with EC50 of 0.22 nM and 0.34-1.3 nM against HIV-1 Ba-L and NL432, respectively. GSK1265744 produces cytotoxicity with CC50 of 6.4, 5.0, 9.2, and 13 μM in proliferating IM-9, U-937, MT-4, and Molt-4 cell lines, respectively. 
|In vivo||GSK1265744 (50 mg/kg) treatment protects rhesus macaques against three high-dose SHIV challenges. |
In vitro strand transfer assay:The inhibitory concentrations of GSK1265744 is measured in a strand transfer assay using recombinant HIV IN. A complex of integrase and biotinylated donor DNA–streptavidin-coated SPA beads is formed by incubating 2 μM purified recombinant integrase with 0.66 μM biotinylated donor DNA–4 mg/mL streptavidin-coated SPA beads in 25 mM sodium MOPS pH 7.2, 23 mM NaCl, and 10 mM MgCl2 for 5 minutes at 37°C. These beads are spun down and preincubated with diluted INSTIs for 60 minutes at 37°C. Next, [3H]-labeled target DNA substrate is added to give a final concentration of 7 nM substrate, and the strand transfer reaction is incubated at 37°C for 25 to 45 minutes, which allowed for a linear increase in strand transfer of donor DNA to radiolabeled target DNA. The signal is read using a Wallac MicroBeta scintillation plate reader.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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.
