Cat. No.: HY-15745
COA Handling Instructions

PSI-7409 is the active 5'-triphosphate metabolite of Sofosbuvir (PSI-7977). Sofosbuvir (PSI-7977) is a selective and highly active nucleotide analog inhibitor of HCV.

The free form of the compound is prone to instability, it is advisable to consider the stable salt form (PSI-7409 tetrasodium) that retains the same biological activity.

Description

PSI-7409 is the active 5'-triphosphate metabolite of Sofosbuvir (PSI-7977). Sofosbuvir (PSI-7977) is a selective and highly active nucleotide analog inhibitor of HCV.

In Vitro

PSI-7409 inhibits the enzymatic activities of these NS5BΔ21 polymerases in a dose-dependent manner. The IC50s for PSI-7409 against GT 1b, 2a, 3a, and 4a NS5B polymerases are 1.6 μM, 2.8 μM, 0.7 μM, and 2.6 μM, respectively. PSI-7409 is a weak inhibitor of DNA Pol α (IC50=550 μM). DNA Pol β and γ are not inhibited by 1 mM PSI-7409. A significant amount of RNA product is made in the presence of 500 μM PSI-7409, about 85%[1]. In clone A cells, the levels of PSI-7409 gradually increases to a maximum concentration of about 25 μm over a period of 48 h. PSI-7409 forms at a much faster rate in primary human hepatocytes, achieving a maximum intracellular concentration of ∼100 μM at 4 h and remains at that concentration for 48 h[2].

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.
