VGD020
VGD020 is a highly potent and selective Sec61 translocon inhibitor. VGD020 suppresses the expression of cell surface CD4 by inhibiting signal peptide-dependent co-translational ER translocation, interferes with the initiation of ER translocation of dengue virus polyprotein, and reduces the expression of Sortilin in breast cancer cells. VGD020 exhibits broad anti-flavivirus and anti-HIV activities. VGD020 can be used in research related to dengue virus infection, Zika virus infection, yellow fever virus infection, human immunodeficiency virus infection, and breast cancer.

VGD020 (0.01-10 μM; 4-5 days) potently inhibits DENV2 replication in Vero cells, and achieves complete antiviral activity at micromolar concentrations[1].
VGD020 (0.01-100 μM; 4-5 days) exhibits low cytotoxicity in Vero cells, with minimal effects on cell viability even at concentrations as high as 100 μM[1].
VGD020 (0.01-10 μM; 4-5 days) potently inhibits DENV2 replication in Huh7 cells, and achieves complete antiviral activity at micromolar concentrations[1].
VGD020 (0.02-2 μM; 48 h) inhibits the expression of viral E protein in Huh7 cells infected with dengue virus type 2 (DENV2), and complete inhibition is achieved at a concentration of 0.4 μM after 48 h[1].
VGD020 (2 μM; 72 h) potently inhibits the expression of viral E protein in Huh7 cells infected with dengue virus type 2 (DENV2)[1].
VGD020 (1 μM; 0-24 h) exerts antiviral effects against DENV2 in Vero cells at the post-entry stage, and retains full activity even when added 8 h post-infection[1].
VGD020 (0.4-10 μM; 18 h) inhibits the expression of DENV2 prM and E proteins in transiently transfected HEK293T cells in a concentration-dependent manner, and its potency is consistent with its antiviral activity[1].
VGD020 (0.4-10 μM; 18 h) does not inhibit the expression of DENV2 NS1 protein in transiently transfected HEK293T cells even at concentrations as high as 10 μM[1].
VGD020 (0.4-10 μM; 18 h) selectively inhibits the expression of DENV2 prM protein, but does not inhibit the expression of E protein, in transiently transfected HEK293T cells[1].
VGD020 (0.15-15 μM) selectively inhibits Sec61-mediated co-translational translocation of DENV2 prM protein into the ER lumen in cell-free assays, with no effect on protein translation[1].
VGD020 (0.15-15 μM) does not inhibit Sec61-mediated co-translational translocation of truncated DENV2 E protein into the ER lumen in cell-free assays[1].
VGD020 (0.4-10 μM; 18 h) induces inhibition of DENV2 polyprotein trafficking, which in turn leads to proteasomal degradation of the precursor; co-treatment with MG132 partially reverses this effect in CHO-K1 cells[1].
VGD020 (0.01-10 μM; 18 h) potently inhibits the expression of 14C-prM62-VSV-G chimeric protein in HEK293T cells, with an IC50 of 308 nM[1].
VGD020 (0.01-10 μM; 18 h) does not inhibit the expression of M21-E62-VSV-G or E23-NS162-VSV-G chimeric proteins in HEK293T cells even at concentrations as high as 10 μM[1].
VGD020 (0.01-10 μM; 18 h) potently inhibits the expression of chimeric proteins containing the DENV2 C14 signal peptide sequence (the major determinant of sensitivity to VGD020), with an IC50 of 41 nM in HEK293T cells[1].
VGD020 (0.01-10 μM; 18 h) potently inhibits the expression of chimeric proteins containing C14 signal peptide sequences from multiple flaviviruses (DENV1, DENV3, DENV4, ZIKV) in HEK293T cells, with its IC50 value stably maintained at approximately 100 nM[1].
VGD020 (18 h) downregulates the expression of sortilin in HEK293T cells in a dose-dependent manner, with an IC50 of 0.5 μM[2].
VGD020 (24 h) potently downregulates CD4 expression in CHO CD4-YFP cells, with an IC50 of 46 nM[3].
