生物活性

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[1][2][3].

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.
