Strand transfer was carried out with RSV IN(1-269) (4 uM) and GU320R(2 uM)in the presence of 50mM NDSB201. Increasing concentrations of STIs were added as indicated at the top; DTG(Dolutegravir) in lanes 3-5, MK-2048 in lanes 6-8, and RAL in lanes 9-11. No STI was present in lane 2, and lane 1 contains the molecular weight markers. Strand transfer products and ODN substrate are identified on the right. CHS, circular half-site; OC target and SC target, open circular and supercoiled target DNA, respectively.

qPCR kinetics of 2-LTRc and integrated DNA forms during a single round of HIV replication in the presence of inhibitors. MT4cells were infected with HIV-1 in the absence (DMSO) or in the presence of 100 nM EFV, 500 nM RAL, 500 nM DTG, 10 μM RDS1611, 10 μM RDS1644, 10 μM RDS1823 added at the time of infection (black bar) or 16 h p.i. (grey bar). Samples were analyzed for (A) total viral DNA at 24 h and (B) 2-LTRc and (C) integrated viral DNA at 48 h. The graph represents the average and standard deviation of three independent experiments. Significant at: p value < 0.05 (*); p value < 0.01 (**); p value < 0.001 (***); p value < 0.0001 (****).

|Description||Dolutegravir (GSK1349572) is a two-metal-binding HIV integrase inhibitor with IC50 of 2.7 nM in a cell-free assay, modest activity against raltegravir-resistant signature mutants Y143R, Q148K, N155H, and G140S/Q148H.|
|Features||A next-generation and two-metal-binding HIV integrase strand transfer inhibitor.|
S/GSK1349572 shows the potent inhibitory effect on nine clinical isolates from integrase inhibitor-naive HIV-2-infected patients with EC50 ranging from 0.2 nM -1.4 nM.  In vitro, S/GSK1349572 inhibits recombinant HIV-1 integrase-catalyzed strand transfer with IC50 of 2.7 nM. Furthermore, S/GSK1349572 potently inhibits HIV replication in cells such as peripheral blood mononuclear cells (PBMCs), MT-4 cells and CIP4 cells infected with a self-inactivating PHIV lentiviral vector with EC50 of 0,51 nM, 0.71 nM and 2.2 nM, respectively.  In vitro, S/GSK1349572 exhibits potent activity against five different nonnucleoside reverse transcription inhibitor--resistant or nucleoside reverse transcription inhibitor--resistant viruses with EC50 ranging from 1.3 nM -2.1 nM. Similarly to that against wild-type virus, S/GSK1349572 shows equivalent activity against two protease inhibitor-resistant viruses with EC50 of 0.36 nM and 0.37 nM, respectively. 
In vitro strand transfer assay:The inhibitory potencies of S/GSK1349572 and other INIs are measured in a strand transfer assay using recombinant HIV integrase. A complex of integrase and biotinylated preprocessed donor DNA-streptavidin-coated Acintillation proximity assay (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 morpholinepropanesulfonic acid (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 INIs for 60 minutes at 37 °C. Then a 3H-labeled target DNA substrate is added to give a final concentration of 7 nM substrate, and the strand transfer reaction mixture is incubated at 37 °C for 25 to 45 minutes, which allows for a linear increase in the strand transfer of donor DNA to radiolabeled target DNA. The signal is read using a Wallac MicroBeta scintillation plate reader.

* 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.
