GS-9160 is a HIV-1 integrase strand transfer inhibitor with an IC50 of 28 nM. GS-9160 elevates the level of HIV-1 double long terminal repeat circles and reduces integration junctions. GS-9160 exhibits selective antiviral activity against HIV-1 in cells. GS-9160 can select for integrase mutants E92V and L74M, and shows synergistic activity with other HIV-1 inhibitors. GS-9160 can be used in studies related to HIV-1 infection.

Description

GS-9160 is a HIV-1 integrase strand transfer inhibitor with an IC50 of 28 nM. GS-9160 elevates the level of HIV-1 double long terminal repeat circles and reduces integration junctions. GS-9160 exhibits selective antiviral activity against HIV-1 in cells. GS-9160 can select for integrase mutants E92V and L74M, and shows synergistic activity with other HIV-1 inhibitors. GS-9160 can be used in studies related to HIV-1 infection[1][2][3].

In Vitro

GS-9160 (range; 30 min) potently inhibits purified HIV-1 integrase strand transfer activity with an IC50 of 28 nM[1].
GS-9160 (serially diluted; 5 days) potently inhibits HIV-1 IIIb replication in MT-2 cells with an EC50 of 2.1 nM and a selectivity index of 1,905[1].
GS-9160 (serially diluted; 5 days) potently inhibits HIV-1 IIIb replication in MT-4 cells with an EC50 of 0.7 nM and a selectivity index of 457[1].
GS-9160 (serially diluted; 5 days) potently inhibits HIV-1 BaL replication in primary human CD4-positive T lymphocytes with an EC50 of 1.5 nM and a selectivity index of 2,667[1].
GS-9160 (tested doses; period sufficient for viral replication and circle formation) blocks HIV-1 integration in SupT1 cells, as evidenced by a 1.9-fold increase in 2-LTR circle levels, with a cytotoxicity CC50 of 600 nM[1].
GS-9160 (tested doses; 48 h) specifically inhibits HIV-1 integration in SupT1 cells, reducing integration junctions with an EC50 of 0.9 nM without affecting late reverse transcription product accumulation[1].
GS-9160 (nanomolar range) potently inhibits HIV replication in vitro, though its activity is reduced in human serum, and it selects for HIV-1 integrase mutations integraseE92V and integraseL74M that are shared with other integrase strand transfer inhibitors[2].

Cell Viability Assay[1]

Cell Line: MT-4 T-lymphoblastoid cells
Concentration: serially diluted (nine concentrations)
Incubation Time: 5 days
Result: Potently inhibited HIV-1 IIIb replication with a mean EC50 of 0.7 nM and a selectivity index of 457, with a mean CC50 of 320 nM.

ELISA Assay[1]

Cell Line: MT-2 cells, primary human CD4-positive T lymphocytes
Concentration: serially diluted; serum conditions included 10%, 20%, 35%, 50% human serum, or HSA + α1-AGP
Incubation Time: 5 days
Result: Increased the EC50 7.1-fold to 15 nM in MT-2 cells treated with HSA and α1-AGP, while 100% extrapolated human serum increased the EC50 6-fold to 12 nM.
Increased the EC50 10-fold to 15 nM in primary human T cells treated with HSA + α1-AGP.

Real Time qPCR[1]

Cell Line: SupT1 cells
Concentration: tested doses
Incubation Time: period sufficient for viral replication and circle formation
Result: Resulted in an approximate 1.9-fold increase in 2-LTR circle levels, indicating blocked HIV-1 integration, with a mean CC50 of 600 nM.

Cell Viability Assay[1]

Cell Line: MT-2 cells
Concentration: serially diluted combination concentrations
Incubation Time: 5 days
Result: Showed highly synergistic activity with all tested antiretrovirals, with MacSynergy II volumes ranging from 153.7 to 410.5 nM2·% and CI values ranging from 0.373 to 0.751, consistent with synergism or moderate synergism.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
